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.
Where our fitters travel
Covering Pontypool means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in NP4, NP44 and NP13, and are happy to quote further out in Cwmbran and Risca. 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 check on a supplied unit
If you have bought a roof lantern yourself, we check four things before fitting. First, the delivery: open it, look for chips, cracks and bent frames, and report any damage to the seller straight away. Second, the size, measured against the builder's opening rather than the external frame. Third, the upstand height above the finished roof. Fourth, the maker's instructions, which set the fixings and sealing. Product warranty claims go to the seller and maker; our guarantee is for how it was fitted.
What we do on the day
- Frame assembled on the kerb in the maker's set order
- Internal trims fitted to the ring beam or upstand
- Roof membrane checked where it meets the lantern frame
- Heat and glare — We talk through the glass options before you order a large lantern.
- Upstand size and tolerance — We check the kerb against the lantern maker's figures before the kit is opened.
What happens on the day
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 roof lantern: one to two days, weather permitting.
Do you need permission in Pontypool?
Wales sets energy limits of 2.2 W/m²K for rooflights and 1.4 W/m²K for roof windows, and new rooflight openings generally need building regulations approval. Replacement units are controlled fittings; we are not registered with a competent person scheme, so ours are covered by a building notice to the council. Planning permission is needed for rooflights in conservation areas, National Parks, AONBs and World Heritage Sites. We check which applies and include the fee in your quote.
What to send for a quick quote
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 NP4. That is enough for a first price.
Common questions in Pontypool
What upstand height and roof pitch does roof lantern fitting need?
It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
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.
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.
