Pitched roof window installation in Horley

Rooflight work is weather work. Membranes, primers and sealants all want a dry surface, so a fitting day in Horley is planned around the forecast rather than pinned to a date regardless of rain. The opening is kept covered whenever it is exposed, and a roof is not left open overnight without a proper temporary seal. That approach applies to every pitched roof window we install, from a new opening to a straight swap or a fit-only job. We cover Horley, the RH6 district and the rest of Surrey.

Fitting across Horley and nearby

Looking at a property near Horley but not quite in it? We work across RH6, RH1 and RH2 and outwards to Crawley, Redhill and Reigate. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Horley.

Your pitched roof windows or ours

There are two ways to do this. Supply and fit means we source a pitched roof window 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.

On the day, we cover

  • Inside lining fitted and left ready for decoration
  • Window frame fixed on its brackets, square and at the right height
  • Insulation collar and vapour layer fitted to stop a cold edge
  • Scaffold or not — We look at the roof height and the window position to see whether scaffolding is needed.
  • Flashing to suit the roof — We match the flashing kit to your roof covering before ordering.

What happens on the day

On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a pitched roof window, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

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.

Getting a price from photos

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, RH6 or nearby, confirms travel.

Common questions in Horley

Will my new pitched roof window leak?

A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your 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 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.
