Coverage in and around Sevenoaks
Jobs across TN13, TN14 and TN15 are part of our normal cover for Sevenoaks. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Tonbridge and Orpington are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.
Your walk-on rooflights or ours
Your unit or ours, the fitting standard is the same. For supply and fit we choose a walk-on rooflight to suit the roof and price it with the installation. For fit-only we work with what you have, after confirming it arrived undamaged, that it matches the builder's opening, and that the upstand will sit at the height the maker asks for. Report any transit damage to the seller, as the product cover is theirs and the maker's. Our written guarantee applies to the fitting itself.
Included in the work
- Protective film removed and the anti-slip surface left clean
- Lifting plan for the unit, including people or gear for the day
- Drainage around the unit checked so water does not lie on the glass
- Weight on delivery day — We plan the delivery and lift before booking any lifting gear or extra hands.
- Units tested to old standards — We check which standard the walk-on unit has been tested to.
What happens on the day
Morning first: the team arrives, introduces itself and walks through the job with you. Dust sheets go down in the room below and along the route in. Then the opening and upstand, or the flashing on a pitched roof, are checked against the unit's measurements. A walk-on rooflight goes in, is fixed to the maker's pattern and sealed into the roof covering. Inside, the reveal is finished as quoted. Before leaving, the team clears debris and talks you through what was done. Most jobs of this type take one to two days.
Do you need permission in Sevenoaks?
Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.
Getting a price from photos
A fast quote needs five things: a photo of the roof from outside, one from the room below, rough sizes of the opening or the space, the roof covering (felt, single-ply, fibreglass, tiles, slate or metal), and a note on access. If you have already bought the unit, add the product link or spec sheet. And give us the postcode, TN13 or a neighbouring district.
Common questions in Sevenoaks
How long does fitting take?
Fitting a walk-on rooflight into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.
Can you replace an old dome without redoing the whole roof?
Usually, yes. If the existing kerb is sound, level and tall enough, a new unit can often sit on it with a fresh seal to the roof covering. If the kerb is rotten or too low, we rebuild it and patch the covering around it rather than stripping the whole roof. This is checked at the survey and included in the written quote, so you know the full scope first.
Can you fit the walk-on 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 builder's opening and the upstand height. The product warranty stays with the maker or seller, and our guarantee covers the fitting.
