– A scrapper is handy but not necessary, you could use your wrecking chisel.

– Bit of sand paper, say 120 dust for removing loose debris and to key if you intend to touch on up the sash window after hanging the cord.
Optionally for decoration and touching up (depending on the status of the window prior to cording – which is something you'll need to make a call on yourself):
– Acrylic, water based sealant, a tube is more than plenty for a few windows.
– Two office epoxy filler for deep blemishes and some normal powder filler the decorators use for facing up.
– Primer, Undercoat, and Gloss.
one. Lay your grit sheets.
It's worth repairing your sash windows, but the get-go and most important job is to ensure you do not make more work from carrying out this chore and damaging your carpet or article of furniture, is to lay some dust sheets. Anywhere you recollect it'southward possible dust and debris might achieve encompass upwards. The second job, which is a trade hush-hush – lay a plastic sheet directly on pinnacle of the grit canvass in shut proximity to the window. Yous'll do this because the sash weights are cast iron and will be rusty, and furthermore, rust will fall off and it will not come up out of carpets. You volition permanently soil your carpet if rust comes into contact with the pile. If yous have a cute cream carpet, and then be fifty-fifty more than aware, because quondam sash window weights are destroyers of lovely calorie-free rug.
How practise I know this you're probably wondering? Approximately ten years agone I quoted on a job with one-time carpets which subsequently the quote was accustomed. A very straight frontwards chore of draught proofing a bay window on the ground floor with an sometime, tired, carpet. The sashes were in relatively good status, and no complications. I sent a team, one of which was an apprentice and greenish behind the ears. Incidentally, that apprentice is doing sash windows still today. Anyway, to cut a painful story relatively short, between the catamenia I quoted, and doing the job, the homeowner in their wisdom, scheduled the carpet fitter. Now, I don't like talking ill of people, and I am a very nice chap, I mean, I am hither educational activity people how to avoid these problems for no benefit other than I assist you lot practice a job I'd be paid for, later on all, but this client, was not the smartest of the hundreds and thousands I've dealt with. They gave me no alert they would install carpet of extremely high quality, pile with so much depth, that your feet literally sink as your walking, and ever so comfortable, and in light cream, off white most, total luxury. Anyhow, our green sash window amateur puts grit sheets downwardly, without plastic, drops the weights directly onto the cloth dust sheet, totally unaware for four hours he'due south ruined a £1000 + carpet, worth more than the job! The grit sheets pulled upward, the stain is obvious, it won't come out from hoovering, it'southward fifty-fifty more unlucky its been clammy, the rust is now in the carpet for expert.
Three professional carpet cleaners all arrive, at my expense of form, and all with the verdict the pile will be damaged earlier it's cleaned. So we chalk that i down to feel so? I highly recommend you correctly lay a plastic dust sheet, and so take a further stride which I will go into at the right time in this commodity. This applies to whatever valuables that may be damaged, non simply the carpet!
2. Fix your tools, materials, and a infinite to supervene upon a broken sash cord.
The key to replacing a broken sash cord is organisation, following this educational activity exactly, will make anyone capable of doing this task in less than an hour if it's simply a lower sash, assuming you can swing a hammer well plenty! Prepare a space, with a grit sheet that you can lean the sash. Ensure theres no trouble leaning the sash confronting the wall, and it won't damage paintwork or wall paper. The key to making this worthwhile, by doing this yourself, is that no other sacrifice or harm is made in the process elsewhere. You wan't your fourth dimension working on your sash windows to improve the value of your property.
3. Remove the staff bead and set it for refit.
Removing the staff bead is quite easy, take your utility pocketknife and make a cut between the frame and the beading. This will reduce the likelihood of pigment beingness damaged or chipped. A indicate to note, near injuries and cuts occur when the utility pocketknife slips and your hand catches the frame. Be careful and steady, with a house arm and purpose. Once you've scored both sides (you lot demand not remove the lower and upper staff bead for a unproblematic re-cord) you can identify your chisel to remove the staff dewdrop. Ever insert your chisel just above the lower sash. This way your chisel can go correct through to the other side, without striking the lower sash, and this loosens the staff dewdrop much more finer.
Depending on how well fastened, you may need to practise this college upwards the frame, but normally with i hand you'll pull away from the frame, applying pressure level, and the other, use the chisel to lever gently. This method volition ensure you do not snap the staff bead. Once both sides removed, yous'll demand to clean this staff dewdrop up for refitting. The best style of getting a good job is to ensure the staff bead is clean, and can sit nicely against the frame when we are ready to re-attach. Pull pins through the staff bead, it'll exercise all damage on the back edge of the timber, which y'all'll be fitting confronting the frame. This will reduce time making skillful afterwards. You'll notice caulk or filler on the frames border, this also needs cleaning off.
To do this I use a scraper specifically designed for the job. Take a look at the picture fastened above, but for a few windows information technology's probably not worth spending £twenty. Only use the side of your wrecking chisel, pulling down the frame and staff beads being careful. If y'all intend to do some DIY sash window sill replacement or DIY draught proofing withal, you shouldn't be without one! If your sash windows are painted close or stuck then this is the ultimate frame cleaning tool.
four. Remove lower sash.
Permit's presume it was an upper sash cord that bankrupt for a minute and not a straight forrad lower sash re-cord, and your two lower sash cords are in tact. Before cut them, just lift the sash, and bank check it's well counterbalanced. If the sash is slowly creeping down, you'll know y'all need to check the weight and if it stays put nicely, you lot'll know it's fine, on the other hand, and this is quite possible. pulling the sash down is difficult. Information technology's a sign of two things. The first which is very rare, existence the weights are too heavy and demand replacing with lighter ones, or secondly your pulleys are non rolling freely which is very common for sash that are over painted. In any event this is a great time to diagnose those problems by simply sliding the window up and down. Cut the cords with your sharp side cutters and lift the sash out the whole. Place the sash on the dust sheet, and with your side cutter, remove the old cords from the side of the sash. This will range from like shooting fish in a barrel, to extremely difficult.
The times I've seen nails and so long they would nearly striking the glass simply blows my listen. How anyone could go to the lengths of removing their sash, but wouldn't spend fifteen minutes in a hardware store buying one inch annular rings shocks me. Be organised. Breaking the glass would make the whole process uneconomical!
5. Remove the parting bead.
Take a quick look at the diagram provided hither, you'll see the parting bead is fitted into the pulley style. You need to insert your chisel as parallel to the parting bead equally is possible to ensure you remove the parting bead without breaking information technology. Start at the bottom and work your way up slowly. Your far more probable to snap this mould than the staff bead, so it's all most sensible pressure and taking it steadily. Once removed pull any pins through the dorsum edge, in the same style as the staff bead to avoid damage to the face up timber. Then clean out the parting dewdrop groove well and besides clean off the parting bead, set up for re-fitting when the time comes.
Take a look at the picture above to understand the parting bead, and why you need to point the chisel bract into the box. The departing bead slots into the groove and your effectively levering it out.
Equally you can come across we will offset at the bottom, slowly working our manner upwards. This gives you your all-time gamble of keep the trim in one piece. Exist warned, information technology's fragile.
6. Remove the lower sash weights.
Previously in the "remove lower sash" stage, you cut the lower sash cords. Now is the time to call up them. Pay close attention, get the order right, and this will be a cakewalk. Open up the pocket carefully and so identify the pockets on the floor.
If the sash was under or over weight, y'all need to weigh sash, and determine what add weight is required(assuming the weights are under). Underweight is far more mutual because interestingly a sash weight loses a pound in rust every hundred years. So by now Victorian sash weights every bit a pair are going to be 3 lb lighter than when they started! Credit should get to my farther for instruction me that trick, he'southward been involved in sash windows for thirty years at present. I'll go into where to buy sash weight add ons subsequently. If overweight it'south catchy – are you lot skilled with a grinder? You can cutting the weights down. More than preferable is that you replace the weights for the correct size. In that location are hundreds of scrap yards in London carrying sash weights. They are not used for bit all that much as they sell much better as a 2nd hand sash weight, which is handy. Simply google "2d paw sash weights London" and you lot'll take plenty of pick considering lots of people demand to replace a broken sash cord. Just to signal out, over weight is always because of the previous installers error, or randomly the window was glazed with a thinner glass. I would say overweight does not occur to more one in a hundred windows. Y'all'd be extremely unlucky if you got this scenario on your first get!
Architectural save yards always have sash weights as well. I don't go for the weights, I go for the beautiful old Victorian beehive catches that have been cleaned up. They toll an arm and a leg just don't they just wait the role. I normally requite them to clients at cost toll when they are having sash repairs, or draught proofing installed. Retaining period property features is a adept way of maintaining and protecting the value of your home.
I've side tracked myself with architectural salve, sorry dorsum on topic of replace a cleaved sash cord:
So to get the weights out we removed the pocket and placed them neatly on the flooring. Note the pocket is hinged at the top, ever, unless information technology was not made correctly. So lever from the bottom and the pocket will just pop straight out. Then carefully lay the weights on the pockets.
Call back I pointed out an actress pace to save your rug? Hither information technology is, lay the weights on those pockets, off direct contact with the grit canvas. This is preventative. If for case the plastic split, y'all'd be vulnerable to damaging your carpet once again. Next, remove the old sash cords from the weights and we are ready to movement on.
7. Remove the upper sash to replace a broken sash cord.
Pull the upper sash downward and check the weighting, following the lower sash procedure. A great tip here is to pull the upper sash right downwardly to the sill, and and so cut the cords. Y'all significantly reduce the chances of breaking glass, and the job is much easier – if you lot have a hand that'due south good because you lot tin can gently lower the string to stop your sash weight crashing down within the frame. Take the sash out and and then remove the old cords, as we did for the lower sash, then neatly balance the upper sash on the lower – you'll exist refitting the upper sash first anyway and so it's the right lodge. Then take the sash cords out and check the weight of the upper sash in the same mode as we went into detail for the lower, with a slight exception. Replace a broken sash cord trade tip: If the weights are a couple of pounds over, this is ideal as information technology'll pull the sash snug against the head of the window when you come to refit.
8. Re-cording to supersede a broken sash cord.
So nosotros've correctly weighed the sashes, and added any weight required (if it was required). Remember if using add together weights, that are a pound each. Allow's just imagine yous needed 4lbs. Identify two lbs either side to keep the sash in perfect residue, not just upwards and downwardly, but side to side. Fitting all the weight on i side would pull the heavier side toward the frame, and event in less smooth travel of your sash when finished.Permit'due south use the example of a sash that is now 24lb, merely you but have ii 10lb weights. Resist the temptation of just buying one 14lb weight, and having lopsided weight. It appears to be ideal but the travel volition be affected as mentioned earlier. Attempt your best to find ii twelves get-go before cutting this corner. Recall you can ever employ the other weights again, and maybe fifty-fifty become a disbelieve on the ones your replacing with. Please also consider if you lot currently take 6lb weights they are virtually useless for windows. If a scrap 1000 offers you a couple of pence for them do non be insulted. It's merely they are very hard to detect a use for and they are in total oversupply. Useable weights that are of high value are 9lb and up. These you should not requite away for a few pence, and if that'south all that is on offer, keep them.
With your mouse you fabricated earlier, attach the sash cord, and so thread this through the pulley and downward the back of the box, then pull the cord through the box. Take a look at this motion-picture show beneath for example. The mouse lead goes kickoff and and so where you've fastened the string department of the mouse to the cord, when the lead becomes visible lower down, you can pull the cord through that is attached to the cord.
The second picture below here shows how the mouse has been pulled through and then this has fatigued the sash cord with it.
So remove the mouse, adhere the correct weight to the string you lot've merely pulled through the box. Ensure a good knot that won't pull through the weight hole. If for example you sent the mouse through an upper sash caster, you lot'll attach an upper sash weight. Once the sash weight is attached place the sash weight back in the box. Y'all may find a thin piece of timber. This is chosen a departing slip. Ensure if it'south a top sash weight, the weight is placed to the outside of the box, and the lower sash weight to the inside. It is simply a divider to stop weights clashing, and hence called "parting slip". Getting this wrong will result in snagging, which volition be frustrating.
If your unsure, take a await at this image of the back of the box, which will explain much more clearly than I tin can with words lonely. I wish I knew the name of this book, I'd beloved to credit them.
Once yous've correctly figured out the parting skid, and which side to be on, pull the weight to the pinnacle ensuring it'south not snagging or caught, then on a step, take your side cutters and a 40mm console pin, and button the pin through the cord, and slowly release, so the pin stops the cord just falling to the bottom of the box. Repeat this to all four cords and we are ready to hang the top sash. Come across image below
This stage is the nearly important because you can hands go wrong, take your time, ensure the string runs freely, and is non snagged on the parting slip or even the frame. Sometimes old bits of brick and mortar can fall into the frame and crusade a blockage. If this happens you lot'll need to give the cord a good tug in order to costless it, sometimes y'all might fifty-fifty demand to open up the frame, if that'south the example, unless your extremely competent at DIY you might desire to seek professional sash window advice.
nine. Hanging the top sash.
Accept note of the groove down the side of the sash and lightly mark the face up border of the sash at the bottom of the groove. We volition now place the sash in the opening and you'll probably demand a friend to agree the top sash against the sill, while you take a top sash cord and ready to cut the cord to the same height as the mark you fabricated which indicated the bottom of the groove. Once put back together this guarantee'due south total travel of your sash window. Now have your friend temporarily remove the sash, and you lot'll install six annular rings, an inch autonomously on each of those 2 top sash cords that you just cut.
I just wan't to clear something up here. Notice the cord is not to the lesser of the groove? Information technology is set to the bottom of the useable groove. Make certain you don't mark right at the bottom, marker where depth is enough that the string tin can sit within the groove. If yous've an older, higher quality sash, your groove will start shallow like this, and and then over the infinite of about four inches, get to a point deep enough that the cord will sit inside the groove. If you adhere the cord outside of the groove in anyway, so yous volition scar the frame, every bit the sash slides, and the sash won't work very well. In fact, if the fit was already good, information technology might finish up being stuck.
Note. Become this adjacent bit right, I've watched apprentices a hundred times hang the sash on the wrong cord. In some cases you'll need to string again if you damage the cord also badly. Offer the sash in and push button the string into the groove, and make sure the cord is at the height of your mark. While your friend holds the sash. Yous hammer the nails into the groove. This tin can be done on your own, in fact all professionals practice, merely it involves leaning against frames and remainder. We demand to remember sash windows are dangerous if done incorrect, you or the sash could fall and it'due south not worth risk just to replace a broken sash string, so a friend to hold is considerably of import. Now the cords are attached, remove the pins that are stopping the weights dropping on the top sash yous only fitted and check the window works properly.
Hither'south where we are at if all went well:
It should slide perfectly if you've followed along to this signal.
10. Install parting bead on a sash window.
Button the departing bead gently back into the groove. It'll fit dainty and like shooting fish in a barrel if you cleaned it up properly. Identify a couple of pins, one at the bottom and one at the peak to agree it well. Then run your sealant gun along the joint betwixt parting dewdrop and frame. Don't go mad, a load of caulk is ugly.
The draught proofing isn't office of the tutorial, this is a professional draught proofing system, only the parting bead principal remains the aforementioned.
11. Attach the lower sash.
Follow exactly the aforementioned procedure for attaching the upper sash with one deviation, when yous cut the cords at the mark y'all've made at the bottom of the grooves, let an extra three inches of length. This will allow the lower sash to close nicely without affecting full travel of the sash. Once yous've checked this sash travels nicely on to plumbing fixtures the staff bead.
12. Attach staff dewdrop and finish up.
Attach the staff bead carefully, assuasive merely plenty room for the top sash to travel smoothly, simply not enough that it's loose and will rattle in the wind. Seal the joint between staff bead and frame with sealant and touch up as you crave. A tip to make the sashes glide at this stage is to oil the pulleys, then spray silicone into the styles. Here is a picture show of staff bead being refitted. The staff bead has been replaced by united states, but the same main applies to re-using. We had to supersede for the draught proofing system.
Now is a good time to get the paint castor out. Sash window ornament is straight forrad if done properly. Beginning prep your surface areas correctly. And then employ an undercoat. If you've purchased a nice quality undercoat and then expect the drying fourth dimension to be in the region of 12 hours. Don't endeavor to shortcut this. Paint must exist cured fully in social club that y'all get the longest service from each fourth dimension you decorate. If the layers are applied whilst tacky, they may never set properly and you'll be able to push your thumb nail into the paint and scar information technology. I am sure y'all've all experienced that problem earlier at present.
I hope you've enjoyed the write up on how to replace a cleaved sash cord and followed carefully you'll save a peachy deal of effort making easy mistakes. Next you lot should consider DIY sash window draught proofing for a good project. There is an piece of cake chance to save energy on your sash windows and do your bit for the environment. This doesn't have to be all that costly either.
