Sash Window Repairs My sash windows need repairing as the wood is very rotten in places. Has anyone any recommendations for a builder they may have used forthis purpose Tweet Comments Showing 19 of 19 Rob H 2 years, 2 months ago Hi we don't usually bother repairing them as the work involved means the cost of replacement is not much more. We fit new double glazed timber sash windows which are the same shape and size as the originals but much more energy efficient. Let me know if you would like a quote 07828 181 738. If they're only slightly rotten a good decorator can usually prolong their life for a few more years. ella l 2 years, 2 months ago hello my husband is carpenter and decorator he has used to repair sash windows if you are interested p/n07786605463 thanks Irksome 2 years, 2 months ago Rob H - sorry to ask a dumb question, but are they 'off the shelf' units fitted to timber frames - I assume so? What is the minimum thickness of frame that the units can fit into & what about triple glazed units? I've got a few windows that need doing, but the existing frames are delicate - in both structure and design and I won't compromise on their replacement - unlike Wandsworth Council who I see have just replaced all the sash windows in Balfern Street (SW11) with uPVC crap. Mark 2 years, 2 months ago Go for UPVC it's easier, cheaper ,warmer and virtually no maintenance! Cathy T 2 years, 2 months ago Oh you lucky things. I live in a grade 2 listed buildings and all we could do with the windows was draught proof them. It does keep out the worst of the weather though. Rob H 2 years, 2 months ago Our windows are hand made replacements made to measure and to match the originals. We take the frame out and replace the lot. They're made from wood and are faithful replicas except for their double glazing and draft proofing qualities. It is possible to replace the sashes into the old frames which is something we do but often even this is more time consuming than replacement. We do put upvc sashes into victorian houses but really only in bathrooms where their resistance to moisture pays dividends (and in the odd loft conversion). Melodyroad 2 years, 2 months ago Hi. I had three or four of my windows done by Fred from Sash Renovation Systems. He did a good job and was very good value! His mobile is 07881 487088. Good luck! Mary S 2 years, 2 months ago A friend of mine, Ben Johnson, specialises in Sash Window repair. www.mysashwindow.com roym 2 years, 2 months ago Chris when you say good value, do you mind saying how much and for what? Molly H 2 years, 2 months ago Ventrolla does refurbs and replacements; very happy with the quality of the service, not sure how it stacks up for pricing, but I suspect it's competitive. mungomuffit inactive 2 years, 2 months ago Hi, from a recommendation on previous Streetlife thread we are getting Paxton Renovation to do ours, but they haven't started yet. They seem really good and to know what they are talking about.Unfortunately, we originally went with another company after getting lured in by their quote that was thousands cheaper than the others. We ended up having to cancel the contract and fight for the rest of our deposit back after they did a really poor job. I don't want to print the name but PM me if you want to know. cjdg 2 years, 2 months ago My firm has spent the last 30 + years repairing sash windows and house timbers as timber decay specialists. The window is the bit set in the brickwork. The sash (double hung) is the sliding up and down bit. As a specialist in historic buildings and someone who for a decade did the lecture work for the SPAB course for building professionals on timber biodeterioration, I normally abhore the use of resins but there is just one that is suitable for window repairs and that is the Window Care system originally from Holland. So, If you have a sash with slightly defective timbers say at the joints it can be repaired using that system and indeed components, usually the bottom rail, can be replaced entirely IF the style joints are OK. I'm with Pollock's Pennies UK presence and http://www.pollocks.atics.co.uk/ cjdg 2 years, 2 months ago It usually takes a lot of experience to determine if it is economic to repair or replace a sash. Generally, if there is more than one joined decayed with each component it is cheaper to renew.If you are going to replace the frame then her are some tips: Use Scots pine for the sill (and the rest) - not "hardwood" (Balsa is a hard wood and Luan - often used - is not durable). If you use hardwood only use a durable one such as Iroko - if you can afford it! Oak is only moderately durable and cannot be treated effectively.Have the pine double vac treated after cutting to size before assembly if possible. If not, treat the whole frame - particularly the sill - in OS borne fungicide with at least 60 minute immersion treatment. Have at least 10 degree slope on the sill. Use a non-emulsifiable glue (so that cuts out Unibond). Prime all end grain with a metallic based primer after all the carrier for the preservative has evaporated off. Use a dpm between window and brick.To draft strip sashes use a product such as Reddiseals which is an easy DIY.I have no problem mentioning one firm, Sash Smart Ltd. I tell you a cautionary tale. I rang up this firm with a view to them doing the work on about 10 windows in my house and gave both my names. The chap who answered the telephone as "Chris" and I asked him for his last name. He refused to give his surname and demanded to know why I wanted to know it. I stated that he knew mine and,asI was not on Christian name terms with him as I did not know him, I would like to know his! He refused to give his surname so I declined to do business with him and discontinued the conversation. I wrote him an email on his website giving my name, telephone number and address and suggested to him that his failure to provide a surname has lost him not only my potential contract but that of my clients. (He had been particularly unpleasant)Next thing I know he, and a heavy mate, came round to my house and ended up saying, "I know where you live now" (which was not difficult because I had told him!) I took that as threat and told him so and he then walked off. You might find these facts helpful in deciding whether or not to use this firm if it is on your short list.The market leaders (no names) are pretty expensive and the top two are 'OK' but not technically that good but will be cleaner arrive on time and have a back up staff that a small firm will not have. You would be better off financially getting a good local joiner together with a builder to follow the advice above and fit them in for you.BTW we no longer do this commercially so I have no vested interest in this post as we are now simply consultants. I'm with Pollock's Pennies UK presence and http://www.pollocks.atics.co.uk/ Jane H 2 years, 2 months ago i would not have gone for upvcc however seeing my friends a+++ energy rated ones looking just like timber in there victorian terrace are great units are fantastic so energy effecient !!! tool just like the real thing slide so beautifully gas fiiled double glazing about £400 a standard sash from internet he orderd and fitted own think glide slide windows..... a great product cjdg 2 years, 2 months ago Ooops! 'Draught' not 'draft' - clearly in writing not carpentry mode! I'm with Pollock's Pennies UK presence and http://www.pollocks.atics.co.uk/ Patsy 2 years, 2 months ago Thank you all for your recommendations and help. I am still deciding what to do but just wanted to say how appreciative I am for all your suggestions and comments. I will let you all know how I get on, once I have made up my mind!!Would dearly love to replace them all but each sash works out roughly £1,400 and with 3 very bad windows, it is too costly. Will most likely go the cheaper option and revamp them!! Ali P 2 years, 2 months ago I can recommend Carpenter Paul Waite 07950 740 543 who did an excellent job draftproofing and repairing my sash windows at a reasonable price. cjdg 2 years, 2 months ago A sash should cost no more than about £200 and glazed at that probably. that is £400 for both.The box frame and two sashes you should be able to get for less than that but do you really need to replace the frames? Send me photos of the windows and I will happily comment on pro bono terms. Probe the suspect areas with a sharp thin knife to see if there is any decay. If you are refurbishing look at this product. http://www.countyconchem.co.uk/windowcare09/website/It is the only one I recommend in over 40 years of dealing with timbershttp://www.countyconchem.co.uk/windowcare09/website/videos.htmlNo connection whatsoever commercially. I'm with Pollock's Pennies UK presence and http://www.pollocks.atics.co.uk/ mungomuffit inactive 2 years, 2 months ago Hi, just to let everyone know ...Make sure that you only pay 5% VAT when you are having your windows draughtproofed/re-furbed. There is an HMRC ruling (link below) that certain energy saving improvements to your house attract the cheaper rate of VAT, but I found that some of the quotes sneakily charged 20% assuming that I didn't know this. They sheepishly adjusted their quote when I queried it!
