With over 30 years’ experience of carrying out sash window repairs, refurbishments and renovations in properties all over the South East, we are confident we can help you too. From our joinery workshop or on site, we can renovate original sash windows regardless of architecture and age of property. See below for details on what our work will entail.

Whether your windows require repairing slide mechanisms, fitting draught proofing or even installing double glazing, contact Sash Window Experts to help maintain your home’s classic features for many years to come.

Timber Decay in Sills and Frames

Are your window sills showing signs of decay because of paint deterioration? Rather than replacing the entire box frame, we can carefully remove the lower box assembly and replace this section with new hardwood, bonding the outlinings with epoxy resin and using the original timber joints to maintain the strength of the box frame.

A two-part repair using our unique epoxy resin is the best way to strengthen the tenon joints that the sashes consist of. After cutting out localised areas of timber decay and rot on sashes, sills and the box frame, we first apply a stabilising solution before the epoxy resin. Once fully cured, we sand down and apply a protective coat of primer.

By piecing in new sections of timber in this way, and carefully matching the original profile of the mouldings, your period sash windows can be restored to their former glory. Whether your property boasts Victorian, Edwardian or Georgian sash windows, the lifespan of your home’s period features will be substantially prolonged.

Before and After

Draught Proofing and Rattling Windows

Are your sash windows draughty and rattly, letting the cold air in and the warm air out? Sash Window Experts offer a comprehensive draught proofing service to deal with badly maintained windows to restore them to perfect working order.

The restoration process involves installing an unobtrusive draught proofing system that won’t impact on the aesthetic look of your period sash windows but will instead let you enjoy major advantages such as a considerable reduction in draught and no more rattling, less outside noise and easy glide windows.

We use quality draught proofing pile to fill the gap between the frame and the window in order to create a barrier against dust and cold air coming in and hot air going out. Using soft brush, low drag draught proofing pile allows the sashes to travel smoothly to open and close the window without damaging the paintwork. The result? Lower heating bills and a cosier home.

Sash Cords, Pulleys and Weights

A complete sash window renovation will focus a great deal of attention on the heart of the operating mechanism: sash cords, pulleys and weights. We start by removing the sashes from the box frame, getting rid of any build-up of paint from the running surfaces, then priming any bare wood as needed.

Once the sashes and box frame are prepared, we check the counter balance weights and pulleys, making adjustments where necessary. At the same time, we discard the old cords and beads and re-cord the windows with our modern, improved sash cords.

Before and After

New Furniture and Hardware

As part of our sash window renovation service, we re-align and, wherever possible, reuse your windows’ original catches to maintain the integrity of your architectural features. If window catches or locks are damaged or broken, we can obtain replacements on request.

We have a range of traditional and modern window fittings in stock, including locks and catches in a selection of styles, materials and finishes. Of course, other hardware products for sash windows and doors, and casement windows and doors, can be ordered if necessary.

Double Glazing for Period Windows

At Sash Window Experts, we realise that double glazing is now an essential requirement for modern homes. Compared to single glazed period windows, you can expect to enjoy considerable advantages in terms of lower heating bills and greater energy efficiency, better sound insulation and home security, as well as easier maintenance.

Our skilled artisans use the latest advances in double glazing technology to help upgrade and restore original sash windows and casement windows in your home. We can

  • Supply and fit new double glazed sashed into the original box frame
  • Re-instate double glazed sashes into the original box frame in cases where these were previously changed to modern UPVC or aluminium frames
  • Install a replacement box frame, complete with double glazed sash windows, in cases where these were previously removed.

We offer double glazed hard or soft wood sashes that incorporate warm edge technology that is normally used in modern, sealed double glazing units. That way, all the beautiful period features including original moulding designs and horn detail, can be retained.

Window Security

For your total peace of mind, we work with a large selection of replacement glass and security options to make your home as safe as possible. Cracks in window panes and broken glass are a common issue, which is why we offer a wide range of glass and putty repairs, using clear format, laminated, toughened, patterned, obscure and sealed glass units as required.

What’s more, your building and contents insurance provider will insist on key operated locks to be fitted to any period sash windows; original centre catches are deemed to be not secure enough for modern requirements. Sash Window Experts offer a variety of choices in several finishes, both for modern locks and traditional centre catches, that will comply with current insurance regulations.

What Our Customers Say

Helen Thomas
If I could clone you for all the other work we need to do over the next few years, I would! Thank you Mark for having such a good team in place. And huge thank you to Gary, Alex, John and Glen for taking such care of our windows and giving them what they needed after years (decades?) of neglect. Your attention to detail and 'doing it right' was very much appreciated, and your ability to solve problems was awesome. Helen & Tim, Godalming
Roxana Avanu
Amazing service from start to finish, no issues and no drama. The name Sash Window Experts is well chosen. Mark and his team - Gary and John were extremely helpful and professional and the end product - new sash sound proof double glaze windows upstairs and the kitchen triple sash window restored was top quality. I am very grateful to Sash Window Experts.
Amy Clarke
Cannot fault Mark and his team. We replaced the original sashes to our 1890's home with new like-for-like hardwood double glazed sash windows, and apart from being warmer, quieter, cleaner and altogether much smarter, you really wouldn't tell the difference - an amazing feat! They are absolutely beautiful windows, so well crafted and fitted, and the restoration of rot on the original box is imperceptible. Gary was friendly, clean, professional, and safe throughout the fitting, and very thoughtful in causing minimal disruption to the home. Absolutely thrilled with everything from the service to the price to the final finish. Delighted with them. Would recommend in a heartbeat.
Alison Fordham
We were nervous about getting our Victorian French windows restored and had received a ridiculously high quote. Sash Window Experts came in at a good price, gave a timeframe that worked with our schedule and did a great job. All as promised. The fitter, Gary, put the doors back in with great care and took time made sure they worked smoothly and also discussed any queries with us. Definitely made the job value for money. Very happy customers! We are looking forward to beign able to open our doors again and enjoy the garden. Thank you Mark and Co!
Peter Jones
Our house is Edwardian and has the original sash windows from 1906. I really want to make sure that any double glazed windows did not look out of place - so the woodwork, including the side bars etc should still be very thin to match the originals. I was fearing ending up with fat wooden bars but Mark took me to see a previous customer and I was happy to see the woodwork there and it put my mind at rest. We went for the thin Krypton windows. Now the windows are in they look very good and match very well. To be fair to everybody, we will not know until the winter how well they remedy our warmth and condensation issues in the house but are confident we made the right choice. Other suppliers would not do separate window panes and instead would only do a large window with a false wooden strip down the middle to make them look like two. We did not want that. The carpenters, Steve and Gary turned up on time (early actually) and got on with the job very efficiently and left no mess behind. I am very happy with the company and the windows.
Natasha Birley
Mark and his team are amazing. They restored our sash windows and doors. Mark is really knowledgeable and passionate and explained the process to me so I knew exactly what they would be doing. Once the work commenced I was amazed by how well they draft proofed the windows. They took so much care and the guys were polite, tidy, timely and a joy to have around. I would absolutely recommend the team to anyone thinking of restoring their windows, they look AMAZING!
Rachael Smith
