Frameless rooflight installation in Wandsworth

Glass is heavy, and bigger units get heavy fast. Fitting a frameless rooflight in Wandsworth means planning how it travels from the delivery vehicle to the roof without chipping an edge or straining a back. Smaller units go up by hand with two fitters. Larger ones may need a hoist, a scaffold loading bay or a crane, and we tell you at quote stage if that applies. Once it is up, the fitting follows the maker's sequence: seat, fix, seal, finish. We take on work like this across Greater London.

Fitting across Wandsworth and nearby

Looking at a property near Wandsworth but not quite in it? We work across SW18, SW15 and SW6 and outwards to Earlsfield, Putney and Fulham. 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 Wandsworth.

Your frameless rooflights or ours

There are two ways to do this. Supply and fit means we source a frameless rooflight 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.

Included in the work

  • Lifting gear arranged for heavy single panes where two people cannot safely carry
  • Upstand built to the maker's drawing within its stated tolerance
  • Roof covering turned up and finished under the glass overhang
  • Drainage at the overhang — We check how water leaves the glass where it oversails the kerb.
  • Tolerance on the upstand — We build frameless kerbs to the maker's tolerance rather than to normal carpentry accuracy.

A typical installation day

Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a frameless rooflight: one day, weather permitting.

Planning, building control and Wandsworth

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

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 SW18. That is enough for a first price.

Common questions in Wandsworth

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.

Can you fit a rooflight in winter or when it is raining?

Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.

Do you cover Wandsworth?

Yes. Fitters travel to addresses in Wandsworth and the surrounding districts, including SW18. 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.
