Programme of works
Phased replacement across a building, priced from a survey
Guide ranges for supply & fit, per unit; site set-up priced separately. 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 Prestatyn
Covering Prestatyn means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in LL19, LL18 and LL17, and are happy to quote further out in Rhyl and Flint. 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 do on the day
- New units fitted, sealed and weathered into the roof covering
- Phasing agreed so occupied areas stay dry and usable
- Kerbs checked and packed, adapted or rebuilt where needed
- Fire performance near boundaries — We check how close the rooflights are to the site boundary and to escape routes.
- Glass or polycarbonate — We compare glass and polycarbonate units against the roof, use and budget.
How a fitting day runs
Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a commercial rooflight: about a day per unit, longer on big roofs, weather permitting.
Planning and building rules in Wales
Non-domestic rooflight work in Wales follows the Welsh Approved Documents: energy limits for the glazing, fire checks near boundaries and over escape routes, and building control for new openings. Planning depends on the building and its location. We set out the route on your quote.
What to send for a quick quote
What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around LL19 and we will come back with a quote or a survey date.
Common questions in Prestatyn
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 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.
How long does fitting take?
Fitting a commercial 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.
