We had the pleasure of Sash Window Preservation replacing sash window to our property and Jack and Nick completed the works in a polite and professional manner. I was was in the construction industry for over 45 years and find it hard to find any fault with these men. They were polite, reliable and very neat and tidy and nothing was too much trouble. They have done an excellent job I would highly recommend Jack and Nick and of course Sash Window Preservation. 10/10

We recently had our old sash windows restored and partially replaced, and the result is excellent. The craftsmanship is outstanding — the new windows are beautifully made and blend seamlessly with the originals, preserving the character of the property while significantly improving performance. Installation was carried out to a very high standard. The team — Adam, Ricky, George, and Gary — were professional, efficient, and clearly took pride in their work. Attention to detail was evident throughout, and everything was left clean and tidy at the end of each day. Overall, a very high-quality job from start to finish. Highly recommended.

Gary and his wonderful team (George, Nick and Jack if I remember correctly) replaced our 120 year old Edwardian sash windows for exact modern double glazed replicas and we could not be more pleased. Beautiful windows, there is much less noise and the rooms are no longer cold. They draught proofed an older window too which now is like new. Fast and efficient service, and certainly fairly priced. Thank you! 10/10.

Timber Sash Window Repair Watford

Trusted Timber Sash Window Repair Watford

Watford grew rapidly in the latter half of the 19th century once the railway made London an easy run. Much of the housing stock was terraced and semi-detached, with timber box sash windows. Sash Window Preservation offers sash window repair in Watford for homeowners who wish to keep their original sashes working.

Watford Sash window rot repair and rebuilds

Sashes here suffer from the same handful of problems. Most of these are due to sashes being old and repainted rather than serious decay. Cords wear through, pulleys stop turning, and staff and parting beads get painted so solidly that the sashes become immovable. Draughts get in around worn meeting rails. Rot is usually found low down on the sill and bottom rail.

All of these problems can be repaired on site where possible. Smaller areas of rot are cut back to sound timber, treated and rebuilt using Repair Care two-part epoxy resin, with spliced timber repairs using traditional carpentry where more wood has gone.

The benefits of repairing sash windows in Watford

Many of the original windows remain and are often hidden under layers of paint. Rickmansworth and Croxley Green have older cores of Georgian and Victorian housing, while Kings Langley has a historic high street near the Grand Union Canal. A Georgian sash is built differently from a late Victorian sash and as such requires different replacement parts. Our aim is to save as much as possible before anything new is made; where a sash is past saving, a replacement is made to match in Accoya timber in our own Norwich workshop.

We travel down from Norwich to cover the whole of the Watford area. Specialising in period windows since 2010, Sash Window Preservation is CERTASS qualified and a CHAS accredited contractor. Our teams clean up every evening and leave windows secure overnight.

Sash Window Repair FAQs

Do you provide sash window services in Watford?
Yes, we do. We cover the town centre and the older residential streets of Nascot, Oxhey and West Watford, the roads around Cassiobury, and the surrounding towns and villages of Bushey, Croxley Green, Rickmansworth, Abbots Langley and Kings Langley. If you live nearby but aren’t listed, please get in touch.
Do you work on Victorian and Georgian properties in Watford?
Yes. Nascot, just north of the town centre, has some of the best Victorian and Edwardian properties in the town, with tall sashes and bay windows to the principal rooms. Oxhey, around Bushey station, is largely Victorian terraces. The homes in West Watford are late Victorian terraced houses, and Bushey and Bushey Heath have a mix of Victorian cottages and larger period homes.
Can sash window efficiency be improved in older Watford homes?
Yes. Many houses here are near busy roads or the railway, and secondary glazing is often the most effective way to keep noise out. Even simple draught proofing can make a big difference to comfort. We can also fit double glazing or vacuum glazing within restored sashes.
Can sash windows be upgraded while keeping their original appearance?
Yes. Secondary glazing is fitted inside the room and leaves the original sashes intact, and any new parts are matched to how each window was built. For a listed house or one in a conservation area, we repair like for like and work with the conservation officer.
Why should I choose Sash Window Preservation for my Watford property?
We specialise in period windows and save as much as possible before anything new is made. A video call works well for an initial appraisal, or book an onsite visit, for a free onsite or video quotation and a written quotation. Call 01603 908 252.
