In Northolt, as everywhere, if the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame. Send photos and we'll tell you what we think has failed.

What you might be seeing
- The room is noticeably hotter than the rest of the house in summer
- Furniture or flooring fading under the lantern
- Clear, uncoated glass in an older lantern
Why it happens
Orientation
South- and west-facing lanterns gain the most heat in the afternoon.
No ventilation
A lantern without opening vents traps warm air at ceiling level.
Covering Northolt and nearby
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.
Northolt is around 11 miles from Westminster, and both are within our Greater London coverage.
If you're just outside Northolt, we also cover Greenford (1 mile), Harrow (3 miles), Southall (3 miles).
What should you expect to pay in Northolt?
Guide price for solar control and self-cleaning glass upgrades: £345–£895 ex VAT (£414–£1,074 inc VAT), per glass unit. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in England?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.

Solar control and self-cleaning glass upgrades in Northolt: questions
How do I get a price for solar control and self-cleaning glass upgrades in Northolt?
Send a few photos of the lantern and the problem, with your Northolt postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
Do you need to visit to price solar control and self-cleaning glass upgrades?
Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.
Can you add a film instead?
Films are cheaper but can affect the unit's warranty and may not suit sloped double glazing. We'd rather replace the unit properly.
Does self-cleaning glass mean no cleaning?
It reduces cleaning on the outer face but still needs rain and occasional rinsing, and the inside still needs cleaning.
