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
Jobs across DN8, DN7 and DN3 are part of our normal cover for Thorne. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Goole and Doncaster are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.
Fit-only or supply and fit
If you have bought a roof access hatch 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.
On the day, we cover
- Locks, catches or handles checked from inside and out
- Kerb checked or built square, level and to the maker's height
- Hatch fixed and weathered, with the membrane dressed up the upstand
- Access hatch or smoke vent — We confirm the hatch is only for access and not part of a building's smoke ventilation.
- Clear opening size — We check the hatch's clear opening rather than its outer size.
A typical installation day
Where a job takes one day, the split is usually structural work first and finishing second. Early on, the fitters cut or prepare the opening, trim where needed and prepare the upstand or flashing. Then a roof access hatch is lifted in, fixed and made weathertight so the roof is sound before anyone moves inside. Plasterboard, trim and filler for the reveal come after. Each evening the work area is swept, and at the end the glass is cleaned and the team talks you through what was done.
Do you need permission in Thorne?
In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.
Help us quote accurately
A fast quote needs five things: a photo of the roof from outside, one from the room below, rough sizes of the opening or the space, the roof covering (felt, single-ply, fibreglass, tiles, slate or metal), and a note on access. If you have already bought the unit, add the product link or spec sheet. And give us the postcode, DN8 or a neighbouring district.
Common questions in Thorne
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.
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.
Will my new roof access hatch leak?
A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your quote.
