Guide ranges for supply & fit. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building control fees, where a job needs them, are shown as their own line.
Coverage in and around Crowthorne
Distance is rarely the deciding factor. A roof in Sandhurst, 2 miles from Crowthorne, gets the same survey, the same written quote and the same fitting process as one in RG45, GU47 and RG40. What changes the price is the job itself: size of unit, roof type, access and lifting. Yateley, around 2 miles out, is treated the same way.
Buying your own, or letting us supply
Your unit or ours, the fitting standard is the same. For supply and fit we choose a roof lantern 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.
What the job includes
- Glass lifted and laid into the frame by hand or with gear
- Roof membrane checked where it meets the lantern frame
- Upstand checked for size, level and square before the kit is opened
- Upstand size and tolerance — We check the kerb against the lantern maker's figures before the kit is opened.
- Level, not to a fall — We set or check the kerb level unless your lantern's maker says otherwise.
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 roof lantern 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 Crowthorne?
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 RG45, and we can price it.
Common questions in Crowthorne
Can you remove and dispose of the old rooflight?
Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.
Do you cover Crowthorne?
Yes. Fitters travel to addresses in Crowthorne and the surrounding districts, including RG45. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.
Do I need planning permission for a rooflight in Crowthorne?
Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in England. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.
