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 Thornaby-on-Tees
Jobs across TS17, TS18 and TS16 are part of our normal cover for Thornaby-on-Tees. 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 Stockton-on-Tees and Yarm 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
- Phasing agreed so occupied areas stay dry and usable
- Access, edge protection and fragile-roof covers planned before work starts
- Roof survey of every unit, kerb and the fragile areas around them
- Glass or polycarbonate — We compare glass and polycarbonate units against the roof, use and budget.
- Working around occupied buildings — We plan noise, dust and access around the people using the building.
From arrival to clean-up
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.
Planning, building control and Thornaby-on-Tees
On commercial buildings in England, new rooflights and changes to roof structure go through building control, and replacements in non-dwellings also need building control involvement unless fitted by a scheme-registered installer, which we are not; load-bearing or structural glass always goes through building control. Fire rules matter near boundaries and over escape routes, and smoke vents must be certified to BS EN 12101-2. We confirm the route and the paperwork for your building before work starts.
Details that speed up your quote
Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, TS17 or nearby, confirms travel.
Common questions in Thornaby-on-Tees
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.
Will my new commercial rooflight 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.
Do you cover Thornaby-on-Tees?
Yes. Fitters travel to addresses in Thornaby-on-Tees and the surrounding districts, including TS17. 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.
