Guide ranges for supply & fit, per dome; building control notice fee extra on homes in England and Wales. 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 warrant fees, where a job needs them, are shown as their own line.
Fitting across Helensburgh and nearby
If you also own a property or a business unit in Greenock, Vale of Leven or Dumbarton, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and G84, PA23 and PA24 sit comfortably within that pattern.
Buying your own, or letting us supply
There are two ways to do this. Supply and fit means we source a dome 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.
On the day, we cover
- Membrane checked where it meets the kerb, with small repairs made
- Kerb top cleaned of old sealant, fixings and loose felt
- Inside checked for drips and the trim refitted
- Multi-skin domes and energy — We fit multi-skin domes rather than single-skin ones as replacements.
- Fragile dome safety — We treat old domes as fragile at all times.
What happens on the 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 dome 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.
Planning and building rules in Scotland
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.
Getting a price from photos
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, G84 or nearby, confirms travel.
Common questions in Helensburgh
What upstand height and roof pitch does dome 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.
Do you cover Helensburgh?
Yes. Fitters travel to addresses in Helensburgh and the surrounding districts, including G84. 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.
How long does fitting take?
Fitting a dome 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.
