Fitting across Portslade and nearby
Jobs across BN41, BN3 and BN1 are part of our normal cover for Portslade. 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 Hove and Shoreham-by-Sea are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.
Already bought your unit?
There are two ways to do this. Supply and fit means we source a roof lantern that suits your roof and install it, so one company answers for both the product choice and the fitting. Fit-only means you buy the unit and we install it. With fit-only, the product warranty stays with the maker or seller, and our written guarantee covers the fitting work. Both routes get the same checks on the opening, the upstand and the maker's instructions before anything is fixed.
What the job includes
- Glass lifted and laid into the frame by hand or with gear
- Caps, end closures and ridge trims fitted and sealed
- Internal trims fitted to the ring beam or upstand
- Heat and glare — We talk through the glass options before you order a large lantern.
- Following the build order — We assemble lanterns in exactly the sequence the instructions give.
From arrival to clean-up
Fitting days start with a look at the sky. If rain is due, the order of work changes so the roof is never left open to it. A typical day for a roof lantern runs like this: set up access, protect the room, open up the roof or prepare the existing kerb or frame, check sizes, fix, seal, then finish inside. On jobs that take more than a day, the opening is weather-sealed overnight. The last hour goes on tidying, waste removal and a walk-round with you.
Planning, building control and Portslade
Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.
Before you get in touch
For fit-only work, the product details matter most: the link, the spec sheet, or a photo of the label on the box. Alongside that, send pictures of the roof and the ceiling below, approximate opening sizes, the type of roof covering, and how someone would get onto the roof. For supply and fit, the same photos and sizes do the job. Finish with your postcode, such as BN41.
Common questions in Portslade
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.
Do you cover Portslade?
Yes. Fitters travel to addresses in Portslade and the surrounding districts, including BN41. 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.
Can you replace an old dome without redoing the whole roof?
Usually, yes. If the existing kerb is sound, level and tall enough, a new unit can often sit on it with a fresh seal to the roof covering. If the kerb is rotten or too low, we rebuild it and patch the covering around it rather than stripping the whole roof. This is checked at the survey and included in the written quote, so you know the full scope first.
Tell us your postcode, BN41 or close by, and what you want fitted. We will reply with the next steps and a quote.
