Dome rooflight replacement in Crawley

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 dome rooflight replacement in Crawley, internal finishing is listed so you can see whether it is included or left for your decorator. That way a dome rooflight looks right from the room below as well as from outside. We cover Crawley and properties throughout West Sussex.

Areas around Crawley we cover

Looking at a property near Crawley but not quite in it? We work across RH11, RH10 and RH12 and outwards to Horley, Horsham and East Grinstead. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Crawley.

Buying your own, or letting us supply

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 dome 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.

Included in the work

  • Kerb checked for rot, size and height before the new unit goes on
  • Adaptor or packing fitted where the old kerb needs it
  • Inside checked for drips and the trim refitted
  • Is the kerb sound? — We check each kerb for rot and movement before quoting a dome swap.
  • Kerb size and adaptors — We measure every kerb against the new dome's sizes.

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 dome 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 a few hours per dome.

Planning and building rules in England

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

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 RH11. That is enough for a first price.

Common questions in Crawley

Do you need scaffolding to fit a rooflight?

Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.

Can you fit the dome 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.

How does payment work?

Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.

Send a few photos and your RH11 postcode, and we will put together a written quote for the job.
