Window & Door Fitters Mitcham & Morden | Window Fitters Ltd

Window & Door Fitters Serving Mitcham & Merton

Are you looking to improve your home's thermal comfort and reduce your energy bills in Mitcham or the Borough of Merton? Window Fitters Ltd provides professional, energy-efficient window fitting, double glazing replacement, and custom door installations. Our fitters have over 10 years of experience delivering high-quality results across South London.

Whether you require a full Supply and Fit service or need Installation-Only glazier labour for client-sourced frames, our local window and door contractors deliver precision fitting and building control compliance.

Mitcham's housing stock is wonderfully varied - from the Victorian and Edwardian terraces around Cricket Green to the inter-war semis of Pollards Hill and the post-war estates near Eastfields. Many Mitcham homes still have original single-glazed timber frames or early double-glazed units from the 1990s where the seals have since failed, causing misting and condensation. We specialise in upgrading these properties with modern, energy-efficient systems that dramatically reduce heat loss and improve security - all while maintaining the street-facing character of your home.

Why Mitcham Homeowners Trust Us

• Dedicated Fitting Team: We are a direct, employed team of experienced carpenters and window installers. We never outsource your project to unvetted subcontractors.
• PAS 24 Security Standards: All replacement windows and entrance doors we fit feature PAS 24 security hardware, including multi-point shootbolt locks, anti-snap cylinders, and toughened safety glass.
• Building Regulations Compliance: We ensure every window and door installation meets or exceeds UK building regulations for thermal efficiency (Document L, U-values 1.2 to 1.4 W/m²K), safety glazing (Document K), and ventilation (Document F), coordinating directly with local building control for inspections and sign-off.
• Fully Licensed and Insured: Backed by £5M public liability insurance for a safe, worry-free installation process.
• 10-Year Guarantee: Standard 10-year warranty covering frame profiles, sealed glass units, and a 2-year warranty on locks, handles, and hinges.

uPVC Profile Systems for Mitcham Properties

We offer four leading UK profile systems, each achieving A-rated thermal performance. All are available in a wide range of colour finishes including Anthracite Grey (RAL 7016), Rosewood, and Cream White.

• Deceuninck 2500: Cost-effective chamfered-edge system - 1.2 to 1.4 W/m²K U-value. Ideal for whole-house replacements on a budget.
• Liniar Sculptured: Rounded-edge aesthetic with superior 1.2 W/m²K insulation. Popular for flat conversions and modern refurbishments.
• Rehau T70C: Premium structural rigidity - 1.2 to 1.4 W/m²K U-value. Best where long-term durability matters most.
• Profile 22 Optima: Trusted UK system with a 1.2 W/m²K U-value and clean modern lines.

Our Comprehensive Fitting Services

• Double Glazed Windows: uPVC casement, tilt-and-turn, and traditional vertical sliding sash windows from Deceuninck, Liniar, Rehau, and Profile 22.
• Aluminium Window Solutions: Slimline frames offering maximum glass area and excellent structural strength - ideal for the modern extensions popular in Mitcham.
• Composite Entrance Doors: Premium security doors with polyurethane or solid timber cores and GRP skins, fitted with PAS 24 multi-point locks.
• Aluminium Bifold & Sliding Doors: Enhance your patio or garden entrance with smooth, draftproof sliding door systems in Anthracite Grey or any RAL colour.
• Fire Doors: FD30 and FD60 certified fire doorsets for flats, HMOs, and commercial properties. See our fire door installation page.
• Lock and Glass Repairs: Lock repairs, broken glass replacement, and misted unit double-glazing repairs - often without replacing the full frame.

Whether you need a full Supply and Fit service where we source and deliver the new frames, or have already purchased your windows and require an Installation Only expert fitting, we are ready to assist. For example, we frequently help Mitcham homeowners install custom bifold patio doors they purchased separately.

Featured Mitcham Project

We recently completed a double glazing upgrade for a Victorian period property near Mitcham Cricket Green. The project involved replacing drafty single-glazed timber sashes with custom-fabricated uPVC vertical sliding sash windows. The new frames retain traditional run-through sash horns and decorative glazing bars while delivering an A-rated 1.2 W/m²K U-value for exceptional energy efficiency.
