About Windows & Doors

Checking the work before paying

Open and close every sash before the team leaves. Look for even gaps of 3 to 5 mm around the frame. Run a damp finger along seals to find air leaks. Check sills with a spirit level. Water-test doors with a hose for 10 minutes before signing the completion form.

Seals, gaskets and the compression test

Good windows depend on rubber gaskets that compress evenly around the sash. Ask to see the gasket profile and check that corners are mitred or vulcanised, not glued. After fitting, close the sash on a piece of paper; if you can pull it out without tearing, the compression is too loose.

Damp around frames and where it hides

Damp patches near the head or sill often point to a broken bridge in the frame, not the wall. Run your hand along the reveal and feel for cold spots. Ask the fitter to drill a small inspection hole in the frame cavity and confirm the insulation is continuous.

Disposal of the old units

Old glass and timber frames count as construction waste and should not go in a normal bin. Ask the fitter to break down the old units on site and take them away, leaving the driveway clean. Keep the waste transfer note with your invoice for proof of legal disposal.

How long installation takes

A standard casement window swap takes 1 to 2 hours per unit. A full house of 8 to 10 windows usually finishes in 2 days. Front doors take 3 to 5 hours, French doors up to a full day. Rendering, plaster touch-ups, or structural repairs add extra time to the schedule.

Ventilation and trickle vents

Newer windows must include trickle vents or a mechanical extractor to meet building rules. Removing them causes mould and stale air, even with double glazing. Keep trickle vents open in kitchens and bathrooms. The 2-position slider lets you regulate airflow without leaving the window cracked open.

Guarantees and paperwork to keep

Ask for a written warranty covering frames, glass units, and hardware separately. Sealed glass units often carry a 10-year fog-free guarantee. Installation labour should be warranted for at least 2 years. Keep the FENSA or equivalent certificate for insurance and future property sales.

Threshold detail for external doors

External door thresholds should sit 15 mm above the finished floor to keep out driving rain. Low thresholds look neat but need a proper drip groove underneath. Ask the fitter to show the drainage path and the silicone seal at the sill before they fix the frame in place.

Acoustic glass for busy streets

If you face a road or railway, acoustic laminated glass cuts noise by 6 to 10 decibels over standard double glazing. The panes have a sticky interlayer that dampens vibration. Ask for the Rw rating in writing and compare it across quotes rather than trusting vague terms like soundproof.

Picking the right window frame

Frames come in uPVC, aluminium, timber, or composite. uPVC needs little care and holds heat well. Aluminium is slimmer but adds thermal breaks to fight condensation. Timber looks classic but asks for repainting every 6 to 8 years. Ask the fitter which profile rating matches your wall and local weather.
