Guide ranges for supply & fit. 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?
Jobs across BT38, BT37 and BT36 are part of our normal cover for Carrickfergus. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Newtownabbey and Bangor are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.
What we check on a supplied unit
Which works out better, buying your own or letting us supply? It depends on what you value. Buying your own gives you control of the product and what you pay for it. Letting us supply puts the whole job, unit and fitting, under one written quote. On a customer-supplied unit we still measure it against the opening, look at the upstand, and inspect the condition it arrived in. Warranty on the product sits with whoever sold it, while the fitting carries our own guarantee.
What the job includes
- Upstand built to the maker's drawing within its stated tolerance
- Kerb squared across the diagonals before the glass is ordered or fitted
- Lifting gear arranged for heavy single panes where two people cannot safely carry
- Glass weight and access — We plan the lift for a frameless pane before the delivery is booked.
- Drainage at the overhang — We check how water leaves the glass where it oversails the kerb.
How a fitting day runs
Where a job takes one day, the split is usually structural work first and finishing second. Early on, the fitters cut or prepare the opening, trim where needed and prepare the upstand or flashing. Then a frameless rooflight is lifted in, fixed and made weathertight so the roof is sound before anyone moves inside. Plasterboard, trim and filler for the reveal come after. Each evening the work area is swept, and at the end the glass is cleaned and the team talks you through what was done.
Planning, building control and Carrickfergus
In Northern Ireland, the energy standard for a new or replacement rooflight or roof window in an existing home is WER Band C or a U-value of 1.6 W/m²K, under Technical Booklet F1. Cutting a new opening alters the roof structure, so a building control application is expected; confirm with the council's building control team. Planning permitted development covers many rooflights on houses if they stay below the ridge, project no more than 15 cm on a road-facing slope and sit at least 0.5 m from the ridge, eaves and verges.
What to send for a quick 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 BT38. That is enough for a first price.
Common questions in Carrickfergus
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.
Can you fit the frameless rooflight I bought online?
Yes, fit-only is one of our core services. Send the product link or spec, photos of the roof and rough sizes, and we can usually price it from those. Before fitting we check the delivery for damage, which should be reported to the seller, plus the size against the builder's opening and the upstand height. The product warranty stays with the maker or seller, and our guarantee covers the fitting.
