Sash Windows Draught Proofing

Windows Painting and Paint Spraying

Restoration designed to last

Dedicated to continuously improving our work and raising standards to the next level,  we only use the highest quality materials available that are designed to last. We use Accoya and Tricoya timbers, which are rot-proof and are guaranteed to last for at least 50 years. Accoya and Tricoya lamination protect windows for decades, resulting in a renovated window outlasting any replacement one.


On-site Paint Spraying

There are many reasons people choose us when it comes to restoring their sash windows. One of them is our innovative techniques in spray painting.  We adopt a special paint spraying technology that allows us to give you a high quality, professional finish without the need to remove your windows. 

Paint spraying is the best option when it comes to redecoration. Using a brush by hand can lead to uneven paintwork, compromised surface protection, paint drips, and even brush bristles left in the paintwork. Paint spraying gives a very smooth, even finish.

What’s more, we restore sash windows in St. Albans all year round, even during the winter season. In colder months we use specialist paints, which dry at temperatures as low as 0°C.

As a part of windows restoration project we can also paint and refurbish any exterior woodwork and masonry.

Recently painted windows

Often rotten wood is left untreated under a fresh coat of paint. It leads to even more expensive repairs being needed in the future.
