Commercial rooflight installation in Crowthorne

Builders and extension firms in Crowthorne often want the rooflight stage of a project handled by a specialist fitting team. We step in once the roof deck or battens are ready, fit a commercial rooflight on your upstand or ours, detail it into the membrane or tiles, and leave the opening ready for the plasterer. Homeowners get exactly the same service directly. In each case the job is quoted in writing first, with any access or lifting needs spelt out. Jobs around RG45 and the neighbouring districts are welcome.

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.

Fitting across Crowthorne and nearby

Fitters travel to the job, so the address is what counts. In Crowthorne that means postcode districts RG45, GU47 and RG40, and the same teams can just as easily take on work in Sandhurst, about 2 miles away, or Yateley at roughly 2 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.

On the day, we cover

  • Kerbs checked and packed, adapted or rebuilt where needed
  • Access, edge protection and fragile-roof covers planned before work starts
  • New units fitted, sealed and weathered into the roof covering
  • Working around occupied buildings — We plan noise, dust and access around the people using the building.
  • Fire performance near boundaries — We check how close the rooflights are to the site boundary and to escape routes.

Fitting your commercial rooflight, step by step

Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a commercial rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes about a day per unit, longer on big roofs.

Planning, building control and Crowthorne

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.

Before you get in touch

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 RG45 and we will come back with a quote or a survey date.

Common questions in Crowthorne

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.

What upstand height and roof pitch does commercial rooflight 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.

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.
