We recently had all of our sash windows double glazed by Sash Window Experts and are very pleased with the whole process. Mark and his team were fantastic from start to finish. They were always on time, polite and incredibly considerate of being in our house. They did a fantastic job of replacing the old Victorian sashes with new double glazed units and we can't recommend them highly enough.

These guys fully deserve their 5 star status, the work that they do is exceptional. Having bought a new period property with windows that were in need of attention we contacted several companies, and chose Sash Window Experts on the basis of Mark’s original survey and quote. Mark showed his love for repair and restoration during the initial visit, and came up with options and solutions to look at windows and doors in our house. Work started on time, and was completed to a very high standard. Given the size of our project we had a variety of people on site at different times, all of whom were a pleasure to have around, and who have that same love for their craft that Mark has. A special shout out to John, who worked with us on a number of things, and always came up with a great solution. We’d highly recommend Sash Window Experts.

Mark, Lisa and their team - Steve, Matt, Ollie and Pete repaired 9 badly decayed sash windows on our Victorian house in a conservation area. The work was finished to high quality, beautifully done and beautifully painted. The team was careful and considerate throughout. They kept to time and came in slightly under the quote value, accounting for elements of the original frames that they were able to repair rather than replace. I would wholeheartedly recommend them for work in a heritage setting.

I cannot praise this company enough. Mark and the entire team, who renovated all the rotten, old and drafty sash windows in our small flat, have been amazing. Gary, Steve and Ollie were, without exception, professional, courteous, great craftsmen and clean and tidy. The quality of the windows, both from the workshop and on site renovations is excellent and the style exactly as the old windows once were. Communication was also easy. I can highly recommend this company. Thanks to all the team.

This is the second time we have used Sash Window Experts, and we went back to them for hardwood double-glazing of our second bay window because we were so pleased with how professionally they worked previously, and the excellent results. They were prompt and attentive as ever - real experts in their field. We're delighted with the standard of their work, and would highly recommend them. The windows look great. Update: We have now (May 2024) used Sash Window Experts for the third time for hardwood double-glazed sash windows for our kitchen and second bedroom, to complete window renovation in our flat. They're as professional as ever, prompt and efficient, clean up well after themselves and the work was completed to a high standard in two days, as they said. We continue to recommend sash Window Experts.

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 sash window 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.

How Our Sash Window Service Works in Sussex

Every job in Sussex starts with a proper assessment. Here’s what to expect from first contact through to completion.

1. Free Survey in Sussex

Mark or a member of the team visits your property to assess each window in person. There’s no charge and no obligation to proceed.

2. Work Carried Out On-Site or at Our Joinery Workshop

Depending on the scope, work is carried out at your property or in our joinery workshop in Surrey. Meticulous care is taken every step of the way.

3. Your Windows Left in Beautiful Working Order

Once all work is complete, your windows are left restored, fully functional and ready to use.

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 sash window 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.

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.
