FAQ - Doors

uPVC is low-cost and low-maintenance; composite offers a timber look with better rigidity and insulation; aluminium is slim, strong and great for large openings; timber is warm and repairable but needs periodic repainting. The right choice depends on budget, style, and exposure.

Quality doors use multi-point locking, security-rated cylinders, reinforced hinge points and laminated or toughened glass. Look for doors tested to recognised standards (e.g., PAS 24) and consider optional upgrades like hinge bolts and anti-snap cylinders.

Replacing a door like-for-like rarely needs planning permission (listed buildings and conservation areas can differ). Building Regulations still apply (thermal performance, safety glazing, access). In the UK, approved installers can self-certify compliance via schemes like FENSA or Certass.

Check the door’s U-value (lower is better), quality of weather seals, and glazing spec (low-E, warm-edge spacers, argon fill). A well-fitted door with proper thresholds and draught seals can noticeably reduce heat loss and improve comfort.

Composite doors have a rigid, insulating core with a GRP/thermoset skin for strength, stability and a timber-like finish. uPVC doors are lighter and cheaper, with good insulation but typically less rigid and with fewer design textures.

A straightforward replacement usually takes half a day to a full day. We’ll survey, remove the old frame, install and seal the new door, fit hardware, make good internal trims, and take away the waste.

Wipe frames and thresholds with mild soapy water; avoid abrasive cleaners. Lubricate hinges/locks annually, check seals, and keep drainage/thresholds clear. Timber doors need repainting or re-oiling periodically following the manufacturer’s schedule.

Typically: 10 years on the door/frame, 5 years on hardware, and 5–10 years on glazed units (varies by manufacturer). Ask about an insurance-backed guarantee and what’s covered (finish, colour stability, moving parts, installation).
