About Windows & Doors
Door material pros and cons
Composite doors combine a timber core with a glass-reinforced plastic skin and resist warping. Solid timber looks great but swells in wet seasons. uPVC doors stay stable but can fade after 10 years of strong sun. Steel doors give the best security but need a thermal break to stop cold transfer.
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.
Common mistakes during fitting
Foam filling the entire gap stops the frame from moving with temperature changes. Packers left behind under the sill create cold bridges. Silicone applied over dirty trim peels within months. Ask the fitter how they seal the perimeter and how they pack the frame before screwing it in.
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.
U-value and what it means for your bill
The U-value measures heat loss through the whole unit, frame plus glass. Lower numbers mean better insulation. A standard double-glazed unit sits around 1.4, while better options drop to 1.0 or below. Ask the supplier for the certified U-value for the exact frame and glass combination you order.
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.
Glazing beads and how to remove them
Glazing beads hold the glass inside the frame. External beads are safer against intruders, internal beads are easier to service. Ask which type you have and how to pop a bead out without breaking it. Keep a spare bead set aside in case one cracks during future reglazing.
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.
Making good the plaster after fitting
New frames often leave a 10 to 20 mm gap around the perimeter that needs filling. Ask whether the quote includes making good the plaster or just the foam and silicone seal. Photograph the wall before work starts so any cracks afterwards are easy to pin on the fitter.
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.
