Window Restoration by Mitchell & Dickinson

Worried that your period windows and doors have deteriorated so much that they might not make it through another winter? It’s a common issue.

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

Our teams have amassed a huge amount of experience restoring and renovating sash windows to older properties across North London and surrounding areas such as Tottenham, Wood Green, Edmonton, Stoke Newington, Finsbury Park, Holloway, Palmers Green and Finchley plus other areas in this magnificent city.

Sash Window Restoration North London

Skilled craftspeople with high-tech solutions

Our highly skilled craftspeople can restore your doors and windows (including sash windows) as part of our CosyGlazing secondary glazing insulation or as a standalone service. All of our craftspeople are trained in-house and employed fully by Mitchell & Dickinson, passing their skills down through the generations.

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. They 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 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.

Preserving our architectural heritage is important, but it’s not just about the aesthetics. Restoration of your existing windows and doors is also best for the planet. The whole life carbon of our existing period housing stock is preserved when you restore rather than replace, too. 

While we have your windows out to restore them it also makes sense for us to draught proof them and install CosyGlazing, our unique, advanced and virtually invisible secondary glazing. You’ll improve the thermal efficiency of your home, reduce heat loss through your windows by 70% and avoid the additional cost and inconvenience of having to have your windows taken out again in future.

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. This means the bonds can last as long as the timber itself, so there are significant benefits.

Your window restoration questions answered

What is window restoration and how does it differ from window replacement?

Window restoration involves repairing and refurbishing existing wooden or sash windows to restore their original beauty and functionality.
