Georgian Sash Windows

During the Georgian era (approx. 1714-1830), casement windows in most buildings were replaced with sliding sash windows which emerged as a fashionable and symbolic architectural feature.

What we now recognise as Georgian sash windows could be seen in many of England’s most important buildings including Hampton Court Palace and Kensington Palace.

Compared to the casement windows of earlier times, sash windows offered both a better aesthetic and greater functionality.

Unlike casement windows, Georgian sashes retained their elegant look whether closed or open, while the ability to open the window fractionally meant better ventilation without the rain getting in.

Boxes of sash windows were installed behind masonry, with components mostly within the box, making sash windows more resistant to moisture damage. As a result, the lifespan of sash windows compared to previous window styles improved significantly.

Today’s Georgian sash windows are some of the oldest original windows still in use. Evoking the elegance of this bygone era is the distinctive 6-pane design on both the top and bottom sashes separated by astragal bars. This design came about as a way of achieving large windows as demanded by Georgian architecture while overcoming the limitations of 18th-century glazing technology.

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.

What Are the Main Problems With Georgian Sash Windows?

Historic timber sash windows will need regular maintenance to ensure that they stay in top condition. Factors that can contribute to the deterioration of your Georgian Sash Windows include:

Paintwork deterioration – Make sure that the exterior paintwork of your property is properly maintained over time so that moisture cannot get into the timber and cause rot. Sash windows will need repainting every 2-5 years on average for maximum protection.

Rotten window sills – If your sills are rotten, this can compromise the integrity of the window structure and needs to be addressed urgently. Whether your window is affected by dry rot or wet rot, Sash Window Experts can carry out remedial window sill repair or replacement as necessary.

Sash cord problems – Your sash windows are counterbalanced by 2 sets of weights that are hung on cords run over a pulley wheel at the top of the window frame. If the weights become stuck or a cord snaps, the window won’t open normally, or at all. Professional attention to repair the window is called for.

Damaged putty – If the putty holding the glass pane in place becomes defective, moisture can seep in and cause deterioration in the timber. Make sure the condition of the putty is assessed on a regular basis and repaired if necessary to protect the window.
