Roof lantern installation in Cobham

What the job costs in Cobham

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.

Covering KT11 and neighbouring districts

If you also own a property or a business unit in Esher, Weybridge or Walton-on-Thames, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and KT11, KT13 and KT14 sit comfortably within that pattern.

Already bought your unit?

A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a roof lantern, photograph it, and tell the seller about any cracks or scuffs, because claims are much easier made early. We will also ask for the model or a link, so we can read the maker's instructions and check the builder's opening size and the upstand height it expects. If everything lines up, we fit it. If not, we explain what needs changing first.

What the job includes

• Roof membrane checked where it meets the lantern frame
• Frame assembled on the kerb in the maker's set order
• Glass lifted and laid into the frame by hand or with gear
• Upstand size and tolerance — We check the kerb against the lantern maker's figures before the kit is opened.
• Heat and glare — We talk through the glass options before you order a large lantern.

What happens on the 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 roof lantern: one to two days, weather permitting.

Planning, building control and Cobham

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.

Getting a price from photos

Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in KT11, and we can price it.
