Rooflight replacement in Gwynedd & Anglesey

We cover 44 postcode districts across Gwynedd & Anglesey, and we fit replacement rooflights in all of them. The work itself does not change from one district to the next. A replacement rooflight still needs a correctly sized opening, an upstand or flashing to suit the roof, and sealing that matches the covering. What does change is access: terraced streets, long gardens, steep pitches, tight parking. We price that honestly in the written quote rather than averaging it out across every job.

Guide ranges for supply & fit; building control notice fee extra 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 control fees, where a job needs them, are shown as their own line.

Towns we list in Gwynedd & Anglesey

From the larger towns to the smaller places in between, we take on rooflight fitting across Gwynedd & Anglesey. The process is the same for a terrace, a farmhouse extension or an industrial unit: details first, written quote second, fitting day third. Remote and island addresses in Wales, where they arise, are covered by arrangement, and we tell you that before quoting.

What's included

  • Kerb inspected for rot, height, level and fall once the old unit is off
  • Packers, an adaptor or a new insulated upstand where the old kerb falls short
  • New unit bedded, fixed and sealed exactly as its maker shows
  • Is the kerb worth keeping? — We decide whether the existing kerb can stay only after checking it for rot, height and squareness.
  • Dome to glass upgrades — We check that the opening and kerb suit a flat glass unit before quoting a dome-to-glass swap.

Rules that apply in Wales

In Wales, a new rooflight opening generally needs building regulations approval, and a replacement needs either a scheme-registered installer's certificate or a building notice to the council. We are not registered with a scheme, so we use a building notice and show the fee on the quote. Rooflights must meet 2.2 W/m²K and roof windows 1.4 W/m²K. Planning is tighter than in England: rooflights are not permitted development in conservation areas, National Parks, Areas of Outstanding Natural Beauty or World Heritage Sites, so we check your address before quoting.

Common questions in Gwynedd & Anglesey

Do you need scaffolding to fit a rooflight?

Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.

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.

Do you offer trade rates for builders and roofers?

We carry out subcontract fitting for builders, roofers, extension companies and commercial contractors. Pricing is per job or per schedule of units, agreed in writing before we start. We can work to your programme, fit on your upstand or build our own, and leave the opening ready for the next trade. Send drawings or a unit schedule and we will come back with a trade quote.
