The Window Sanctuary is a premier installer of the highest quality timber sash windows in Sevenoaks. Designed to reduce your heating costs while adding a touch of charm to the look of your house. Operating across Sevenoaks and the surrounding areas, it has never been easier to experience the highest level of workmanship when it comes to classic replacement windows.
ENERGY EFFICIENT TIMBER WINDOWS THAT OFFER EXCEPTIONAL INSULATION

A rigorous 5-stage process ensures that each of our products is protected and painted, can withstand the elements, and require minimum maintenance. Our method is:
- Stage 1 – A Chemical Dip to Minimise Moisture Absorption
- Stage 2 – A Chemical Dip to Protect Against Fungi, Insect Infestation, and Mould Growth
- Stage 3 – Application of Primer and Undercoats Using Micro-Porous Products
- Stage 4 – Spray Finish First Coat according to Your Colour Choice
- Stage 5 – Spray Finish Second Coat
Micro-porous paints allow all timber fibres to be penetrated and to build up protection from within, unlike cellulose paints which form a skin on the outer face and require time-consuming treatments on a regular basis. To keep new products in pristine condition, it is recommended that a quick wipe down and a further coat be applied after approximately 7 years.
PERFORMANCE
Our timber windows achieve an impressive 1.5 w/m2k overall U value and, when glazed with energy-saving thermafloat warm-edge sealed units, can achieve 1.1 w/m2k. Seals are of Q-Lon to ensure maximum draught-free surrounds and the ultra-tight lockable furniture is PAS 24-compliant. A wide choice of quality fittings are available in a range of complementary finishes.
SEVENOAKS CONSERVATION AREAS
