Rather than replacing your windows when they become draughty, you’ll be pleased to hear that with the right skills, sash windows can be draught proofed very effectively.

The skilled team at Sash Window Experts has over 30 years of experience repairing, restoring and renovating sash windows all over the South East. We offer a range of services that are designed to keep your period sashes in perfect working order, draught-free and beautiful.

Advantages of Draught Proofing

Did you know that sash windows require a 3mm air gap around the sashes so that they can slide past each other smoothly when you open or close the window? Unfortunately, this air gap is also to blame when it comes to letting in air, resulting in rattling, draughty windows, loss of heat and dust ingress.

Luckily, fitting a discreet draught-proofing system can quickly solve these problems, without compromising the visual appeal of your sash windows. Draught-proofing can be an effective way to deliver the following benefits:

  • Substantial draught reduction
  • Eliminating window rattling
  • Reduced outside noise
  • Smoother window operation

At Sash Window Experts, our craftsmen can carry out draught proofing as a standalone service or as part of a more comprehensive window renovation project. Why not take a look at our recent draught-proofing projects here?

Rather than filling in the airspace around the sashes – which would make the window harder to open/close – we fill the gap with a soft brush which creates a barrier against incoming air, dust and outgoing heat. It’s a relatively simple improvement to your original windows that can hugely affect your home’s comfort. In addition to creating a cosier and safer home for you and your family, draught proofing also makes your sash windows more efficient which can save you around £50 per year in heating bills.

Unless your sash windows are in excellent overall condition, you may consider having draught proofing included as part of a full window restoration service. This means your window will also benefit from having new sash cords, parting beads and staff beads fitted, and fresh lubrication applied to the pulley wheels. We can also deal with any minor timber defects.

In the old days, many people chose to have their windows painted shut in order to eliminate draught problems. At Sash Window Experts, we can free up the sashes and replace the cords to restore full functionality to your period window. Having installed a quality draught proofing pile, you’ll find that the sash will travel smoothly to allow the window to be opened and closed without friction – just as it did when it was first installed.

Looking After Your Draught-Proofed Sash Windows

Maintaining your refurbished sash windows is not a difficult job. All it takes is a little regular attention to ensure that your windows will give you many years of enjoyment rather than trouble. The most important thing is to clean the draught seals with warm soapy water on a regular basis, so they remain nice and soft, and to ensure they never get painted over by a careless or inexperienced decorator.

If you have a draught-proofing problem with your period sash windows and would like to discuss the issue with one of our expert joiners, or arrange a free window survey and quotation, please email your enquiry or contact Mark at Sash Window Experts at 01403 602701.

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

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.

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.

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!

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.

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!
