Pitched roof window installation in Greenwich

Greenwich guide prices

Guide ranges for supply & fit. 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.

Areas around Greenwich we cover

Distance is rarely the deciding factor. A roof in Lewisham, 1 mile from Greenwich, gets the same survey, the same written quote and the same fitting process as one in SE10, SE8 and SE14. What changes the price is the job itself: size of unit, roof type, access and lifting. New Cross, around 1 mile out, is treated the same way.

Your pitched roof windows or ours

Supply and fit tends to suit people who would rather not pick a unit from a catalogue. We look at the roof, the opening and how you use the room, then put a pitched roof window on the quote that fits all three. Fit-only suits people who already know what they want, or have one on site. We are happy with either. The difference is who stands behind what: on fit-only, the maker or retailer covers the product, and our workmanship guarantee covers the installation.

On the day, we cover

• Inside lining fitted and left ready for decoration
• Flashing kit matched to tiles, slates or a recessed fit
• Window frame fixed on its brackets, square and at the right height
• Energy limit for roof windows — We check the window's published figures against the energy limit for existing homes.
• Side slopes and neighbours — We check which slope the window is going on before you commit.

From arrival to clean-up

Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a pitched roof window level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes one day.

Planning and building rules in England

In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.

Details that speed up your quote

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 SE10 and we will come back with a quote or a survey date.
