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.

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.

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
