Insulation in London

What we find in London attics

London has one of the largest stretches of untouched post-war housing in the province, particularly north and east of the core, and a very large rental and student-let segment where attics have gone thirty years without anyone opening the hatch. Two things show up repeatedly: original fibreglass batts laid between the joists and nothing over them, so the joists themselves bridge heat straight out; and bathroom fans ducted into the attic rather than through the roof, which is a mould problem waiting for a cold week.

Getting a crew to you

London dates are grouped with the southwest run. Ask early in the season rather than late; once the heating comes on, every attic in the province gets remembered in the same fortnight.

Typical lead time: By appointment, usually within two to three weeks. Nothing about the rebate changes with distance — the programme is province-wide — but the diary does, and autumn fills before anything else.

What the attic stream pays

No energy assessment, one measure, and the tier set by the depth we measure before we start.

Amounts are set by Enbridge Gas and Save on Energy and are quoted from the programme pages — attic stream, assessment stream — checked September 2026.

What we will tell you about your house

• The measured depth, taken at the joist rather than at the hatch.
• Which tier that puts you in, and the dollar figure with the fifty per cent cap applied.
• Whether the soffits are blocked, because deep insulation over blocked soffits causes frost.
• Whether the bath fans vent outside or into the attic.
• If you are already over R–35, that the attic stream will not pay — and what is still worth doing instead.

You get the depth, the tier, the figure and the photographs whether or not you use us.
