Our Services

We understand the importance of restoring beautiful sash windows to their former glory without having to resort to architecturally unsympathetic techniques. At Sash Window Experts, we make it our business to preserve and maintain the original period features that make your home unique. Let us restore and renovate your sash windows so they remain in good shape for you to enjoy for many years to come.

We offer a range of restoration and repair services including glass replacement units for damaged panes using clear float, laminated, sealed, obscure, crown, patterned glazing options and more. We also deal with window sill decay and resolve these issues by removing the existing lower box and replacing it with a new reinforced hardboard sill. In compliance with home security specifications set out by many insurance companies, we can fit a range of traditional centre catches and locks designed to complement the traditional sash window design, keeping the look uniform while improving your home security.

Before and After windows

Sash Window Repairs

Our team of local craftsmen takes great pride in restoring the visual appeal and functionality of sash windows back to their former glory, whether in our joinery workshop or on-site. From slide mechanisms to draught proofing, double glazing and home security, we can help renovate sash windows for all kinds of period properties, enabling you to enjoy your home’s unique character for many more years to come.

Using specialist renovation methods for manufacturing and replicating existing moulding details, our team of experts can carry out precise replacement work from our bespoke joinery workshop. Although your sash windows may look old or appear to be beyond repair, our specialist craftsmen use professional moulding techniques to create a matching profile for your existing sash windows. That way, we can faithfully replace cracked, chipped or rotten timber pieces while keeping intact all those important design features of your original windows.

Window Sills and Frames

Window sill decay is a common problem that can occur as a result of paint deterioration. Rather than replacing the entire box frame, Sash Window Experts carefully remove the existing lower box assembly and replace it with a new hardwood sill section, complete with pulleys and outer linings bonded in with epoxy resin.

In doing so, we use the same original joints to maintain the strength of the box frame. Carefully piecing in new timber sections with mouldings that match the original profile allows us to extend the life cycle of period windows from any architectural era including Georgian sash windows.

Before and After

Sash Window Double Glazing

At Sash Window Experts, we focus on improving old, worn or defective sash windows without resorting to unsympathetic contemporary fixtures. We do this by combining a series of classical and modern techniques to ensure your sash windows are in beautiful running condition.

By keeping up to date with the latest advancements in double-glazing technology, we can provide restoration services that improve the quality of your sash windows, allowing you to reap the benefits of modern window installations. Double-glazed hard or soft wood sashes in combination with a specialist moulding facility to maintain the original design keeps all your essential period features intact. The result is the best of both worlds: beautiful period windows that have been brought up to modern standards.

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

Used these guys to do a total refurbishment on the windows of my 1870s Victorian Villa style house. Incredibly happy with the work and the guys doing it are just superb. On time to the minute every day, clearly take pride in the work they do and super friendly. Would not hesitate to use again!
