Guide ranges for labour and materials, rooflight not included. 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.
Covering SA4 and neighbouring districts
Gorseinon and the districts around it, SA4, SA5 and SA2, all sit inside our working area. So does the ground between Gorseinon and Llanelli (5 miles), and on towards Swansea (5 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.
What the job includes
- Kerb sized from the maker's drawing, internal and external dimensions both checked
- Insulation fitted to the upstand faces to limit heat loss
- Treated timber frame fixed down to the deck and joists
- Size tolerance on the kerb — We build kerbs to a tight tolerance because rooflight glass is made to order and cannot be trimmed on site.
- Height above the finished roof — We set the upstand so it stands at least 150 mm above the finished roof, measured from the top of any ballast, paving or walkway.
From arrival to clean-up
On the day, the fitters check the opening and the roof deck around it, then cut and fix treated timber to the maker's kerb size, square and level, with any fall the rooflight needs built in. Insulation goes on the faces that need it, and the roof membrane is turned up and dressed so the kerb is weathertight before anyone leaves. Most upstand jobs take half a day to a day.
Regulations for Gorseinon properties
For a Welsh home, start with where the house is. In a conservation area, National Park, AONB or World Heritage Site, a rooflight needs planning permission; outside those, permitted development usually covers one that projects 150 mm or less. Side-facing roof windows within 10.5 m of a boundary must be obscure-glazed and fixed. New openings need building regulations approval, and replacements we fit are notified with a building notice, as we are not registered with a competent person scheme. We confirm all of this for your address.
What to send for a quick 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, SA4 or nearby, confirms travel.
Common questions in Gorseinon
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 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.
Do you cover Gorseinon?
Yes. Fitters travel to addresses in Gorseinon and the surrounding districts, including SA4. 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.
Ask for a quote for your Gorseinon roof. Survey dates are offered based on fitter availability once you are happy with the price.
