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.
Fitting across Holyhead and nearby
Looking at a property near Holyhead but not quite in it? We work across LL65, LL64 and LL63 and outwards to Caernarfon, Bangor and Llandudno. 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 Holyhead.
What we do on the day
- Old units removed, with waste taken off site
- Roof survey of every unit, kerb and the fragile areas around them
- 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.
- Fragile roofs and rooflights — We treat every rooflight and the roof around it as fragile until we have checked it.
How a fitting day runs
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.
Do you need permission in Holyhead?
On commercial roofs in Wales, new openings and structural changes go through building control, and fire performance has to be considered where rooflights are near a boundary. Smoke vents must be certified products with controls set up by a specialist. We confirm what applies to your building before quoting.
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, LL65 or nearby, confirms travel.
Common questions in Holyhead
What if my roof opening is the wrong size for the commercial rooflight?
We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.
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.
Can you fit a rooflight in winter or when it is raining?
Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.
