Please see below more details about my sash window repairs, restoration and draught proofing in London. Rot Sash Window: I patch in new wood to sills and frames and also replace sills and frame sections. Rattles will be cured by tightening up the frame etc. Glass And Putty Repairs: Replace broken glass and repair old putty is also part of our sash window refurbishment and restoration process.

How I Draught Proof /Insulate Your Sash Windows and Casement windows and stop the Rattles. The result is a consistent brush seal all around your windows. This Restoration Procedure retains the original look and character of your sash windows. Windows will run more smoothly, as we apply the insulation brushes to front and back of the sashes.

Reduces outside noise levels and stops any rattles. Saves on heating bills. Reduces dust and draughts on sash windows by over 90%. London for the past 20 years. I have outstanding references and I'm happy to provide you with these from any of my clients.

John was efficient and transparent with the survey and quote, and also very flexible about timings. Daniel and his team were polite and careful, putting down dust sheets and cleaning up perfectly when they had finished. They did a fantastic job restoring some over-sized sashes in a Victorian school building and I'm very happy with the results - no draughts and better soundproofing. If you need your sash windows sorting, I would recommend you use John and his team.

John’s team restored 3 sash windows to their former glory for us. An excellent tailored approach to each window with cost and potential cost set out clearly from the start. We couldn’t be happier with the results.

Thorough and excellent work. We had three large stuck and ancient box sashes with leaded weights refurbished - new locks, sash lifts, parting beads, sash cords and all three sliding freely again - and two cheaper spring sash windows fixing where the springs had gone. Cheaper than getting these windows replaced and really satisfying to see the old windows come back to life. John was a pleasure to deal with and meticulous in quoting for the various possibilities to generate a good idea of likely cost. Daniel and his assistant Victor were hard working and left the place spotless after. Wouldn't hesitate

A great job by Jon and his team.
I managed to get a quick home visit and quote on refurbishing 6 x sash windows. The quote Jon gave me was very reasonable in comparison to other quotes I received.
Jon's workers were professional and polite. The job was done as quick as possible and they left the house spotless. The windows are now fully functioning and look good as new.
Would highly recommend Sash Window Repair.
Thanks!

John and his team did an excellent job and I would highly recommend them. All the team I dealt with were very professional and clearly communicated the different options and any potential issues (although in my case there were none) from quote through to completion of the job.
I live in a conservation zone so John's team doing a repair, draft-proofing and repainting of my sash windows was a fraction of the cost of getting custom made new ones. It is like having new windows!

Thanks for a great job. Highly professional approach and great craftsmanship from an independent and long standing business.
John and his team have repaired, draught-proofed and decorated my windows at a fraction of the replacement cost and my 100 year old sash windows are now as good as new!
The process from original contact, the site visit explaining the various options available, through to completion of the actual work was a breath of fresh air. The team only do what needs to be done, there are no "extras" or nasty surprises and they do a great job. They even bring their own biscuits - highly

Thank you for the great work that you and your team did on my 4 sash windows that are more than 30 years old.
You visited the apartment and presented me with a detailed and thorough quotation. The work was done in one day, as promised, the fitters were courteous, professional, timely, and very well prepared. They came with all the tools that they could possibly need, and left the premises in a clean and tidy condition.
My windows rattled, were drafty, and did not move up and down freely. The difference in the before and after was like night and day. The windows now move freely, and there is virtually

The whole team was brilliant - from John acting on our brief, to Daniel coming round - on time - to assess our windows - to a prompt estimate from John of what really needed doing and its likely cost - to the 'guys doing the hard work' coming round and doing it. A bit of a mess during the work - as would be expected - but all cleared up perfectly - and nods and smiles if no long conversations over tea and coffee.
Would happily have the whole team in again. Wish every project could go so smoothly

Having recently moved to London my husband and I are delighted with our new home. The problem of course is that it isn't new but in fact a Victorian property. The property is in a good state of repair, however, the sash windows needed some work and urgently. I am not the type of person who normally writes recommendations, as like most people I lead a very busy life. I have to say though that I found John and his team so helpful that I feel compelled to recommend his services. Our property has four bedrooms and lots of widows that needed doing. I found John to be extremely helpful and upfront about
