Window Installation & Glazing Subcontracting Across Mitcham

Most of our work in Mitcham is labour-only subcontracting for builders, residential landlords, and homeowners who purchase frames independently.

We deploy directly employed two-man glazier teams equipped with vans, tools, and fixings to complete the entire installation to BS 8213-4 standards.

Our Croydon headquarters at 139 Wentworth Road sits under 15 minutes from Mitcham via the A236, keeping travel times short and eliminating unnecessary transit overheads.

We also undertake secondary trade supply and fit for clients wanting frames sourced directly from British manufacturers at trade prices, avoiding retail showroom markups.

Fitting Customer-Supplied Windows and Doors in CR4

If you have ordered uPVC casements, sliding sashes, bifolding doors, or composite doors online, our team provides full labour-only fitting.

We unpack units, check frame diagonals, prepare structural openings, set frames plumb with polymer shims, foam perimeter gaps, and apply external low-modulus silicone.

Customer-supplied frames carry zero liability for manufacturing flaws, damaged profile deliveries, or incorrect sizing. An upfront 30% booking deposit secures your installation dates in our diary, which is non-refundable if site apertures or units are unready upon arrival.

Glazing Solutions for Mitcham Housing Stock

Housing styles across Mitcham require specific installation methods to protect building fabric and comply with UK Building Regulations:

1930s Semi-Detached Bay Windows: Inter-war houses throughout Pollards Hill and Mitcham Common frequently feature load-bearing bays supporting upper floors or roof hips. Under Approved Document A, our fitters never remove timber frames without temporary Acrow propping and the installation of heavy-duty bay jacking posts with load-bearing spreader plates.

Victorian Terraces & Cricket Green Conservation Area: Period properties near Fair Green, Upper Green, and the Cricket Green Conservation Area face Article 4 directions requiring planning approval for front-facing alterations. We fit heritage vertical sliding sashes with authentic run-through horns, slim meeting rails, and double glazing matching traditional proportions.

Rear Extensions & Bifold Doors: Modern ground-floor kitchen extensions require open spans with reliable weather tightness. We fit thermally broken aluminium bifolds and inline sliding patio doors with low thresholds under 15mm conforming to Approved Document M accessibility.

Rental Properties & HMO Conversions: For rental flats in Eastfields and Phipps Bridge, we install high-security composite front doors featuring 48mm solid cores and 3-star anti-snap lock cylinders meeting PAS 24 and Approved Document Q.

Double Glazing Repairs and Misted Unit Replacement

We replace failed double glazed units and repair faulty window hardware across Mitcham and Merton.

When moisture forms between glass panes, the hermetic seal has failed. We measure the unit, supply custom low-E double glazed glass with warm-edge spacer bars, and refit it into existing uPVC, timber, or aluminium frames.

We also replace worn friction hinges causing drafts, adjust misaligned sashes, and fit replacement multi-point door lock gearboxes.

Single-glazier service is available for unit swaps and minor servicing at £260 local or £290 extended per day, or £70 for one-hour local visits.

Building Regulations and Merton Council Sign-Off

All replacement windows and external doors must satisfy current UK Building Regulations:

Approved Document L (Conservation of Fuel and Power): Replacement windows must achieve a whole-window Uw value of 1.4 W/m²K or better to ensure thermal performance.

Approved Document F (Ventilation): Habitable rooms require 8,000 mm² equivalent area background ventilation through trickle vents to stop indoor damp and mould.

Approved Document K (Protection from Falling and Impact): Toughened safety glass is installed in all critical zones below 800mm from floor level and within 300mm of any door.

Approved Document B (Fire Safety): First-floor bedroom egress windows are fitted with side-hung easy-clean friction stays providing at least 0.33 m² unobstructed openable area.

We provide complete documentation packs for sign-off through Merton Building Control or your private approved building inspector.
