Local Coverage
Harlow's housing stock is mostly post-war — different problems, different fixes
Harlow is dominated by post-war 'new town' housing built between 1947 and the late 1970s — Gibberd-era estates, low-rise blocks, and the typical concrete-tile roofed semi-detached and terraced housing across most of the town. That dictates the typical scope of our Harlow work: concrete tile roof repairs and re-roofs (most stock now at end-of-life), full UPVC roofline replacements, and significant volumes of internal refurbishment as the original 1960s/70s interiors get updated.
The exceptions are Old Harlow (pre-war village core, period properties) and Church Langley plus Newhall (modern post-2000 development). Both have very different typical scope — period-style repair on Old Harlow, snagging and modern extensions on Church Langley.
Response time from our Ugley base to anywhere in Harlow is typically 25–35 minutes — well within same-day cover for emergencies and standard surveys.

Local Issues
Common roofing & building issues in Harlow
The dominant call-out across Harlow is end-of-life concrete tile roofs. Marley and Redland concrete interlocking tiles laid on most post-war housing have a service life of 50–60 years — the majority of Harlow stock is now in or past that window. Symptoms are widespread tile slippage (nail fatigue), sagging ridges, soft spots in the felt underneath, and rising winter leaks.
The second most common scope is full UPVC roofline replacement. Original painted timber fascias on 1950s/60s housing across CM17 and CM18 are largely rotten or close to it — once water has tracked behind the painted face, the timber goes quickly. Full strip-and-replace with UPVC eliminates the maintenance cycle entirely.
On the building and renovation side, the dominant scope is whole-house refurbishment of properties bought to update from 1960s/70s spec, single-storey rear extensions on the typical Harlow semi (popular kitchen-diner schemes), and landlord turnaround between tenancies on the substantial rental stock across the town.
