Finchley's homes
The character of Finchley roofs
Finchley is a good illustration of how North London was built. The stock here runs to Victorian and Edwardian terraces, generous interwar semis and a scattering of post-war infill, and the roofs are predominantly steeply pitched slate and clay tile roofs with usable, walkable voids above the top floor. Within a single street you can find a loft you can stand up and walk around in, and one three doors along where the only sensible approach is to work on your knees.
That variation is exactly why we survey before quoting. Two lofts of identical floor area can differ by a substantial margin in price because one has 150mm joists and a wide hatch, and the other has shallow, irregular timbers, a 400mm opening and a cold water tank sitting in the middle of the run.
Locally, many of the larger houses were divided into flats decades ago, so the loft often sits above a top-floor conversion with its own separate access — worth knowing before you compare quotes.

Five ways we keep Finchley homes warm
Every one of these begins with the same free survey and ends with a fixed price agreed before anything starts.
Loft insulation installation
270mm depthTopping up from the 100mm many Finchley houses still have to a full 270mm is the cheapest meaningful energy improvement available to a UK homeowner.
Loft boarding
Storage-readyStorage that does not flatten your insulation. We raise the deck on battens so the full depth survives underneath — the version most Finchley lofts should have had first time.
Loft ladders
Fitted in a dayFixed, stable access instead of a stepladder on the landing. Timber, aluminium or concertina, chosen to suit the space your Finchley home actually has.
Loft makeovers

Questions & answers
Finchley loft insulation — common questions
How long does the work take in a typical Finchley home?
Half a day for insulation alone; a full day for a combined job with boarding, lighting and a ladder. Very large Finchley lofts or heavy strip-outs occasionally run into a second morning, and we tell you that in advance.
Do you remove the old insulation?
Only when it needs to go. Sound, dry wool can be topped over, which saves you the removal cost. Material that is damp, vermin-fouled or collapsed does come out, and we bag it and take it away. Which applies to your Finchley loft is established at survey and priced separately.
