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.
Covering SM5 and neighbouring districts
Jobs across SM5, SM1 and SM6 are part of our normal cover for Carshalton. 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 Wallington and Sutton are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.
What the job includes
- Access, edge protection and fragile-roof covers planned before work starts
- Unit schedule and handover notes for the building's records
- Roof survey of every unit, kerb and the fragile areas around them
- Energy limits for non-domestic roofs — We check new units against the energy limits for non-domestic buildings.
- Working around occupied buildings — We plan noise, dust and access around the people using the building.
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.
Do you need permission in Carshalton?
For non-domestic roofs in England, expect building control involvement for new openings, energy limits of 2.2 W/m²K for rooflights, and fire checks where rooflights sit near a boundary or above an escape route. Smoke ventilation rooflights must be certified products, with controls commissioned by a specialist. We set out what applies to your building on the quote.
Getting a price from photos
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 SM5 and we will come back with a quote or a survey date.
Common questions in Carshalton
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.
Do you cover Carshalton?
Yes. Fitters travel to addresses in Carshalton and the surrounding districts, including SM5. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.
Who is responsible for the smoke-control system?
The building's responsible person, duty holder or managing agent, depending on the nation, is responsible for keeping fire safety systems working. Our part is the rooflight and roof work; the controls, detection and commissioning are handled by a smoke-control specialist, and the quote says who does what.
