Rooflight upstands & kerbs in Seaford

Building an upstand in Seaford starts with the rooflight's own drawing, not a standard size. The kerb has to match the unit's internal dimensions, stand high enough above the finished roof for water to run off, and be level or pitched as the maker asks. We set the timber out to those figures, check the diagonals, insulate and weather it. If the rooflight is not on site yet, send us its make and model so the kerb is built for it.

Coverage in and around Seaford

Our fitters come to you. For Seaford that covers BN25, BN9 and BN10, plus nearby Peacehaven and Rottingdean. We do not keep a yard or showroom in the area, and you do not need to visit one. The survey happens at your property or, for fit-only work, from the photos you send. Dates follow fitter availability, which we confirm when you accept the quote.

On the day, we cover

  • Diagonals measured so the kerb is square before anything sits on it
  • Roof membrane turned up, bonded and finished at the kerb top
  • Fall built into the kerb where the rooflight needs one
  • Energy limit for site-built kerbs — We insulate upstands to meet the limit for site-built upstands, which is 0.35 W/m²K in England and Wales.
  • Fall built in or level — We confirm whether your rooflight needs the kerb to provide a fall or should sit level.

How a fitting day runs

Building an upstand starts with the rooflight's own drawing: its kerb size, height above the finished roof and fall. The team sets the timber out to those figures, checks the diagonals, insulates the outer faces and dresses the membrane up and over. If the rooflight is going on the same day, it is fitted next; if not, the kerb is protected until it does.

Planning and building rules in England

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

What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around BN25 and we will come back with a quote or a survey date.

Common questions in Seaford

Do you cover Seaford?

Yes. Fitters travel to addresses in Seaford and the surrounding districts, including BN25. 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.

Do you make good inside after fitting?

Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.

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.
