uPVC Windows
Our uPVC window solutions combine modern energy efficiency with traditional aesthetics. Available in casement, sliding sash, and tilt-and-turn designs, these windows feature 24mm double glazing with argon gas filling and Low E coatings. The 1.4 U-value ensures optimal thermal efficiency while maintaining structural durability. Suitable for both period and contemporary properties across London and the South East.
Timber Windows
Crafted from sustainably sourced Douglas Fir, our timber windows offer authentic period charm with modern performance. Featuring European Oak sills and 24mm double glazing, these windows meet conservation area requirements while providing excellent thermal insulation. Each installation includes a 10-year guarantee and FENSA certification for regulatory compliance.
Aluminium Windows
Contemporary aluminium window systems deliver slim sightlines with superior strength. Our heritage and modern designs incorporate 24mm double glazing units with argon gas and Low E coatings. These corrosion-resistant windows maintain a 1.4 U-value for energy efficiency while complementing both traditional and modern architectural styles across London.
Composite Doors
High-security composite door solutions combine multiple materials for enhanced durability. Available in single, French, and patio configurations, these doors integrate with our double glazing systems for consistent thermal performance. All installations include FENSA certification and a 10-year guarantee against warping or discolouration.
Secondary Glazing
Cost-effective secondary glazing systems improve thermal efficiency in listed buildings where primary window replacement isn't permitted. Our solutions maintain original architectural features while reducing heat loss by up to 60%. Ideal for conservation areas across London with FENSA-compliant installation standards.
Questions
What areas do you cover for installations?
We operate across London, Kent, and Surrey with a seven-mile radius from our Upper Norwood showroom. Our FENSA accreditation allows work in conservation areas and listed buildings.
Are your installers directly employed?
Yes, we use our own fully trained installation teams rather than subcontractors. All staff undergo continuous professional development to maintain installation standards.
What guarantees do you provide?
All installations come with a 10-year guarantee covering materials and workmanship. This includes protection against warping, discolouration, and mechanical failure of window and door components.
Can you match existing window styles?
Our heritage range replicates traditional designs including flush casement and sliding sash profiles. We can match existing window dimensions and architectural details for period properties.
How long does installation take?
Typical installations complete three to six windows per day with a two-person team. Lead times are three weeks for uPVC/aluminium and 8-10 weeks for timber products from order confirmation.
