Fitting across Grangemouth and nearby
Our fitters come to you. For Grangemouth that covers FK3, FK2 and FK1, plus nearby Falkirk and Alloa. We do not keep a yard or showroom in the area, and you do not need to visit one. The survey happens at your property or, for fit-only work, from the photos you send. Dates follow fitter availability, which we confirm when you accept the quote.
Your flat rooflights or ours
There are two ways to do this. Supply and fit means we source a flat rooflight that suits your roof and install it, so one company answers for both the product choice and the fitting. Fit-only means you buy the unit and we install it. With fit-only, the product warranty stays with the maker or seller, and our written guarantee covers the fitting work. Both routes get the same checks on the opening, the upstand and the maker's instructions before anything is fixed.
Included in the work
- Lifting gear or extra hands arranged for large and heavy panes
- Fall confirmed so rain runs off the glass rather than sitting on it
- Membrane, felt or GRP finished to the frame the way the maker shows
- Fixed or opening — We ask whether you need ventilation before you settle on a fixed unit.
- Weight of large panes — We check the weight of the unit against how we will get it onto the roof.
A typical installation day
Fitting days start with a look at the sky. If rain is due, the order of work changes so the roof is never left open to it. A typical day for a flat rooflight runs like this: set up access, protect the room, open up the roof or prepare the existing kerb or frame, check sizes, fix, seal, then finish inside. On jobs that take more than a day, the opening is weather-sealed overnight. The last hour goes on tidying, waste removal and a walk-round with you.
Regulations for Grangemouth properties
In Scotland, forming a new rooflight opening needs a building warrant from the council, because the roof is being altered. Replacing an existing rooflight complete with its frame doesn't need a warrant, but the new unit still has to meet the building standards, including the 1.6 W/m²K energy figure for windows and rooflights in alterations. Planning depends on the house and where it is: householder permitted development rights don't apply in conservation areas, and listed buildings need consent. We confirm this with you before quoting.
Details that speed up your 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 FK3. That is enough for a first price.
Common questions in Grangemouth
Can you replace an old dome without redoing the whole roof?
Usually, yes. If the existing kerb is sound, level and tall enough, a new unit can often sit on it with a fresh seal to the roof covering. If the kerb is rotten or too low, we rebuild it and patch the covering around it rather than stripping the whole roof. This is checked at the survey and included in the written quote, so you know the full scope first.
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.
Will my new flat 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.
