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 Cwmbran
Our fitters come to you. For Cwmbran that covers NP44, NP20 and NP4, plus nearby Pontypool and Risca. We do not keep a yard or showroom in the area, and you do not need to visit one. The survey happens at your property or, for fit-only work, from the photos you send. Dates follow fitter availability, which we confirm when you accept the quote.
Included in the work
- Old units removed, with waste taken off site
- Unit schedule and handover notes for the building's records
- Access, edge protection and fragile-roof covers planned before work starts
- Glass or polycarbonate — We compare glass and polycarbonate units against the roof, use and budget.
- Fire performance near boundaries — We check how close the rooflights are to the site boundary and to escape routes.
What happens on the day
On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a commercial rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.
Do you need permission in Cwmbran?
On commercial roofs in Wales, new openings and structural changes go through building control, and fire performance has to be considered where rooflights are near a boundary. Smoke vents must be certified products with controls set up by a specialist. We confirm what applies to your building before quoting.
Help us quote accurately
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 NP44 and we will come back with a quote or a survey date.
Common questions in Cwmbran
Can you fit a rooflight in winter or when it is raining?
Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.
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.
