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.
Is your address covered?
Looking at a property near Penarth but not quite in it? We work across CF64, CF10 and CF11 and outwards to Cardiff, Barry and Caerphilly. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Penarth.
What we do on the day
- Access, edge protection and fragile-roof covers planned before work starts
- Phasing agreed so occupied areas stay dry and usable
- New units fitted, sealed and weathered into the roof covering
- Glass or polycarbonate — We compare glass and polycarbonate units against the roof, use and budget.
- Fire performance near boundaries — We check how close the rooflights are to the site boundary and to escape routes.
What happens on the day
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 Penarth
Non-domestic rooflight work in Wales follows the Welsh Approved Documents: energy limits for the glazing, fire checks near boundaries and over escape routes, and building control for new openings. Planning depends on the building and its location. We set out the route on your quote.
Help us quote accurately
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, CF64 or nearby, confirms travel.
Common questions in Penarth
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.
Do commercial rooflights need planning permission?
Like-for-like replacements on commercial buildings rarely need planning permission. New or larger rooflights on non-domestic buildings and blocks of flats usually need checking with the planning authority, because householder permitted development rights don't apply. We tell you what we know about your building and point you to the right team.
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.
