Rooflight replacement in East Grinstead

A rooflight is not finished when the roof is watertight. The inside matters too: the reveal or lining around the opening, the plaster, the trim where it meets the ceiling. Some installers leave that for somebody else. When we quote for rooflight replacement in East Grinstead, internal finishing is listed so you can see whether it is included or left for your decorator. That way a replacement rooflight looks right from the room below as well as from outside. We cover East Grinstead and properties throughout West Sussex.

Guide ranges for supply & fit; building control notice fee extra in England and Wales. 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 East Grinstead

If you also own a property or a business unit in Horley, Crawley or Crowborough, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and RH19, RH10 and RH17 sit comfortably within that pattern.

Fit-only or supply and fit

Your unit or ours, the fitting standard is the same. For supply and fit we choose a replacement 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

  • Kerb inspected for rot, height, level and fall once the old unit is off
  • Roof membrane repaired and turned up where it meets the kerb
  • Packers, an adaptor or a new insulated upstand where the old kerb falls short
  • Leaks that are not the rooflight — We look at the roof around the unit before blaming the rooflight.
  • Is the kerb worth keeping? — We decide whether the existing kerb can stay only after checking it for rot, height and squareness.

Fitting your replacement rooflight, step by step

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 replacement 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, building control and East Grinstead

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.

Help us quote accurately

Keep it simple. Two or three photos, outside and inside. Approximate sizes. What the roof is made of. Anything awkward about getting up there, such as a conservatory below, a narrow side path or no parking. If you bought the rooflight online, the link or model name. Then your postcode in or around RH19. That is enough for a first price.

Common questions in East Grinstead

What is included in the price?

The written quote lists it line by line. Typically that covers fitting labour, fixings, sealants, membrane or flashing materials, any upstand work, internal finishing if agreed, and taking away the waste. For supply and fit, the unit itself is included too. Scaffold, lifting gear and any third-party fees, where needed, are shown separately so you can see what each part of the job costs.

Can you fit the replacement 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.

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.
