Window and door restoration

Worried that your period windows have deteriorated so much that simply adding secondary glazing won’t work? It’s a common issue.

That’s why we employ talented craftspeople in Hampshire who have a wealth of experience from the restoration and marine industries who can restore them to their former glory. We offer what we believe is a rare level of expertise in this field.

Window Restoration Bristol

Skilled craftspeople with high-tech solutions

Our highly skilled craftspeople can restore your doors and windows (including sash windows) as part of our CosyGlazing installation service.

We use reclaimed timbers such as pitch pine and sustainably-grown oak together with epoxy resin compounds. Epoxy compounds are an import from the marine industry that combine with timber better than almost any other bonding and fairing material and can provide restoration with a lifespan equivalent to the original window.

We often meet customers who have been told to replace their windows because they are too decayed and we find we can restore them, replacing only 10-20% of the timber at around one third of the cost of a new hardwood window.

Historic England favours restoration over replacement because it preserves the very high quality old timber, allows you to keep your beautiful old glass, and retains the look and feel of a period property which can be spoiled by the introduction of new windows.

Take a look at one such project …

Window Restoration Bath

Replacement sill milled by our joiners in reclaimed pitch pine. Pitch pine has a similar durability to the quality softwoods found in old windows (in contrast, modern softwoods can rot in under 5 years).

The new pitch pine sill is fitted in position using epoxy resin compounds. Epoxies, while not eco-friendly in their own right, are phenomenally compatible with wood, soaking into the timber and expanding and contracting at the same rate, meaning that the bonds can last as long as the timber itself, so there are significant benefits.

One of our project managers, Sam Stephens, scarfing small sections to the bases of the vertical mullions. The structural bonding properties of epoxies mean that small sections of new timber can be scarfed with great durability, allowing us to preserve 90% of the original timber.

Window Restoration Devon

The final window, primed, with the glass and sashes in place. The end result, following the guidelines of Historic England, retains most of the original timber and glass, and at the same time gives the window a new lease of life.

Where some windows need replacing as part of a larger CosyGlazing or insulation installation, we can provide beautiful, high specification replacement windows.
