Professional Residential Glazing & Fitting Services
Window Fitters Ltd provides specialist residential window fitting, entrance door installation, and glazing refurbishment across Greater London and Surrey from our Croydon headquarters. Our directly employed CSCS glazier crews install energy-efficient uPVC, aluminium, and timber systems compliant with Approved Documents L (Uw ? 1.4 W/m²K), F, and Q, operating on transparent day rates (£540/£580) and fixed unit pricing backed by 5,000,000 pounds Public Liability insurance.
Our experienced fitting teams take pride in every residential installation. We work with HEPA-filtered clean extraction, lay heavy protective floor runners, minimize disruption to occupied households, and ensure every frame is plumbed, mechanically anchored, and weather-sealed with precision perimeter mastic beads.
Architectural Glazing Solutions for Private Homeowners
Every residential property presents unique architectural dynamics, which is why we provide tailored double and triple glazing solutions across London and Surrey:
uPVC and Aluminium Casement Windows
Low-maintenance multi-chambered uPVC casements delivering whole-window Uw values of 1.2 to 1.4 W/m²K, or slimline thermally broken aluminium frames with durable Qualicoat powder coating in popular Anthracite Grey (RAL 7016) and Jet Black. Explore our full range of window installation services.
Vertical Sliding Sash Windows
Authentic period replica sliding sashes for Victorian, Edwardian, and Georgian homes. Engineered with calibrated stainless steel spiral balances, deep bottom rails, and continuous run-through sash horns that satisfy conservation planning criteria while eliminating rattles and draughts. Browse our sliding sash windows.
High-Security Composite and Bifold Doors
Solid timber core composite front entrance doors featuring 48mm slabs, GRP skins, and TS007 3-star anti-snap lock cylinders meeting PAS 24 security standards (Approved Document Q). For rear garden extensions, we fit multi-leaf aluminium bifold doors and minimalist sliding patio screens with step-free low thresholds. Review our door installation options.
Remedial Glazing and Hardware Servicing
If you have condensation inside existing double glazing (failed hermetic edge seals) or damaged lock gearboxes, you do not need to replace the entire window frame. We swap out failed insulated glass units to BS EN 1279 standards and service handles, friction hinges, and multi-point gearboxes. Explore our glazing repairs.

Frequently Asked Questions About Residential Glazing Installations
Review authoritative guidance on replacement timescales, planning permissions, mandatory background trickle ventilation, and trade glazier deployment for residential homes.
How long does a full-house window and door replacement take in an occupied home? +
A standard residential replacement of 8 to 12 windows and 2 external entrance or patio doors typically takes 2 to 3 working days. Our CSCS-certified glazing teams work methodically room by room, removing and securing one opening at a time so your property remains warm, weather-tight, and secure overnight.
Do I need planning permission to replace existing windows and doors in my home? +
For most unlisted residential properties outside designated areas, window and door replacements fall under Permitted Development rights, provided the external appearance remains similar. However, homes in Conservation Areas, properties subject to Article 4 directions, or Listed Buildings require planning permission or Listed Building Consent before changing sightlines, frame materials, or opening styles.
Are trickle vents legally mandatory on replacement residential windows under Approved Document F? +
Yes. Under Approved Document F of UK Building Regulations, replacement windows must provide background ventilation that is no worse than the previous installation. Unless your home has a continuous mechanical extract ventilation (MEV) or mechanical ventilation with heat recovery (MVHR) system, new habitable room windows must incorporate trickle vents providing at least 8,000 mm2 equivalent area, or 4,000 mm2 in wet rooms such as kitchens and bathrooms.
What warranty and insurance protection covers residential glazing installations? +
All qualifying window frames, door systems, and insulated glass units installed under our complete supply and installation contracts are backed by a comprehensive 10-year manufacturer warranty. Every project is supported by our 5,000,000 pounds Commercial Public Liability and 10,000,000 pounds Employers Liability insurance, along with our direct workmanship guarantee.
Can Window Fitters Ltd install residential windows and doors that I have bought myself? +
Yes. Through our installation-only service route, homeowners and builders can purchase frames directly from trade suppliers, online distributors, or manufacturers. Our directly employed glazing teams handle the professional mechanical anchoring to BS 8213-4, toe-and-heeling, perimeter air sealing, and hardware calibration under our comprehensive installation warranty.
How do your fitters protect carpets, floors, and furniture during installation? +
We treat occupied family homes with extreme respect. Prior to commencing work, our installers lay heavy-duty protective floor runners across transit paths, wear clean indoor overshoes, drape furniture in clean dust sheets, and isolate work zones. We vacuum work areas with industrial HEPA equipment daily and remove all old frames for recycling under our Environment Agency Upper Tier Waste Carrier licence CBDL650268.
