Pitched roof window installation in Allerton

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.

Is your address covered?

Allerton and the districts around it, L19, L18 and L25, all sit inside our working area. So does the ground between Allerton and Garston (2 miles), and on towards Halewood (3 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.

Already bought your unit?

Which works out better, buying your own or letting us supply? It depends on what you value. Buying your own gives you control of the product and what you pay for it. Letting us supply puts the whole job, unit and fitting, under one written quote. On a customer-supplied unit we still measure it against the opening, look at the upstand, and inspect the condition it arrived in. Warranty on the product sits with whoever sold it, while the fitting carries our own guarantee.

On the day, we cover

• Flashing kit matched to tiles, slates or a recessed fit
• Insulation collar and vapour layer fitted to stop a cold edge
• Underlay collar or membrane dressed and taped around the frame
• Flashing to suit the roof — We match the flashing kit to your roof covering before ordering.
• Scaffold or not — We look at the roof height and the window position to see whether scaffolding is needed.

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

Replacing a rooflight in an English home is a controlled fitting: it has to be self-certified by a scheme-registered installer or notified to building control. We are not registered with a competent person scheme, so replacements we fit are notified with a building notice, and the new unit has to meet current energy limits. Adding a new one usually means a building regulations application, because joists or rafters are trimmed. On the planning side, most house rooflights are permitted development if they project 0.15 m or less; on a side slope the glass must be obscured and fixed unless the opening part is over 1.7 m above the floor.

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 L19 and we will come back with a quote or a survey date.
