Built for Harrow homes

Around Harrow and the wider county, housing stock runs to Victorian terraces, side-return kitchen extensions and flat-roof rear additions where a roof lantern is the default way to pull daylight deep into the plan. We've specified and supplied for exactly these property types across Greater London, so recommendations come from real local precedent.

Every lantern is thermally broken aluminium as standard, glazed with 28mm argon-filled units, and available with self-clean and solar-control coatings. Supply-only orders include kerb specifications and fitting documentation; installed projects carry our written workmanship guarantee on top of the 10-year product cover.

Harrow, Finchley, Hornchurch and Croydon and the rest of Greater London all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.

Roof Lantern Replacement in Harrow — common questions

Is it worth replacing a working but old lantern?

If it's single-glazed, non-thermally-broken or streaming with condensation, the comfort and energy gains are substantial. We'll be honest on survey if yours has life left in it.

What happens to the old roof or dome?

We remove and dispose of it as part of the installation — the price we quote includes taking the old unit away.

Can a new lantern go on my existing upstand?

Usually, yes. If the kerb is sound and square we fabricate to its exact external size; if it's tired or an odd footprint we fit adapter sections or rebuild the timber as part of the job.

My old roof dome leaks — is replacement straightforward?

Very. Domes sit on the same style of kerb a lantern needs, so a swap to a modern glazed lantern is typically a one-day changeover that also transforms how the room looks and holds heat.

Do you cover Harrow for installation?

Yes — Harrow is inside our standard Greater London coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to Harrow on dedicated glass transport.

What's the lead time for Harrow?

Stocked standard sizes typically deliver to Harrow within 7–10 working days; made-to-measure fabrication adds to that, and we confirm the slot when you order so it lands with your build programme.
