Areas around Wimbledon Park we cover
Covering Wimbledon Park means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in SW19, SW18 and SW17, and are happy to quote further out in Wimbledon and Earlsfield. If your address sits between towns, tell us and we will confirm whether it falls in our normal area or needs travel set out separately on the quote.
What we check on a supplied unit
Supply and fit tends to suit people who would rather not pick a unit from a catalogue. We look at the roof, the opening and how you use the room, then put a conservation rooflight on the quote that fits all three. Fit-only suits people who already know what they want, or have one on site. We are happy with either. The difference is who stands behind what: on fit-only, the maker or retailer covers the product, and our workmanship guarantee covers the installation.
What we do on the day
- Flashings in lead or a matching kit, dressed to the covering
- Rafters trimmed with timbers that suit the existing roof
- Slates or tiles made good around the frame with tidy cuts
- Energy and old roofs — We make sure the rooflight meets current energy rules while suiting an older roof build-up.
- Reusing the original covering — We plan to reuse the existing slates or tiles wherever we can.
How a fitting day runs
Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a conservation rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes one day.
Planning and building rules in England
In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.
Help us quote accurately
Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in SW19, and we can price it.
Common questions in Wimbledon Park
Can you fit the conservation rooflight I bought online?
Yes, fit-only is one of our core services. Send the product link or spec, photos of the roof and rough sizes, and we can usually price it from those. Before fitting we check the delivery for damage, which should be reported to the seller, plus the size against the opening, the flashing kit and the roof pitch. The product warranty stays with the maker or seller, and our guarantee covers the fitting.
What if my roof opening is the wrong size for the conservation rooflight?
We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.
Do you make good inside after fitting?
Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.
