Casement Windows
Our casement windows combine traditional aesthetics with modern energy efficiency. Manufactured using Deceuninck profiles, they feature multi-point locking systems and A-rated double glazing. Available in over 150 RAL colours with optional Georgian bars and stained glass designs, these windows provide security, thermal insulation, and customisation for both contemporary and heritage properties.
Composite Doors
Durable GRP-foam core composite doors offer the appearance of timber without maintenance concerns. Enhanced with A-rated glazing and anti-drill cylinder locks, they provide 19% better insulation than timber-core alternatives. Available in heritage shades and modern finishes, with optional PAS 24 security upgrades for enhanced home protection.
Conservatories
Custom-designed conservatories add living space with thermally efficient construction. Available in six styles featuring insulated walls, floors, and roofing options from leading specialists. Compliant with building regulations and including a 10-year guarantee, these extensions create year-round usable spaces that enhance property value.
Flush Sash Windows
Authentic flush sash windows replicate traditional timber aesthetics using low-maintenance PVC-u. Available in 30 heritage shades including English Oak and Anthracite Grey, with optional dual-colour finishes and decorative leaded patterns. Designed to meet conservation area requirements while providing modern thermal performance.
Bi-Fold Doors
Space-enhancing bi-fold doors create seamless indoor-outdoor transitions. Constructed with thermally broken aluminium frames and double-glazed panels, they feature smooth operation mechanisms and weather-resistant seals.

A good company as we bought our double glazing for the house from them but, unfortunately did not have what we wanted.

Just moved house and can't open the door recently fitted by Colfax. They want 100 to transfer the guarantee. Other companies have done this for free. Doesn't seem worth the money if this is the quality of their workmanship.

Dont use this RIP off company oh and if you are looking for a deal be mind full this company charges 3 times the cost of glass so every glass unit you need you are paying for it x3 that's why the lads arent bothered when they break a unit because the company will still make twice its original cost! Also they employ criminals who are in and out of jail for a load of stuff who also haven't had a DBS CHECK so be careful who you are letting in your house or leaving them while you go off to work Just because I haven't wasted my money with you doesn't take away the truth being on your legal team and I'll contact hull live and present them with true facts that way every one in hull Yorkshire area will know not to use this company
