6 Best Guttering & Fascia Installers in Harrow for 2026

Harrow's housing stock throws up a fair range of guttering jobs, from the bay-fronted 1930s semis around Pinner and Hatch End to the flat-roofed extensions and converted maisonettes nearer Wealdstone and South Harrow. Older properties often still have cast iron guttering that's been painted over for decades and needs replacing rather than patching, while newer builds tend to have uPVC systems that just need a clean and a few clips replaced. Because so many of these houses sit close together with shared drives and overhanging trees, blocked gutters causing overflow onto next door's fence or a neighbour's car is a common call-out here, so installers who know the area tend to get booked up around autumn when the leaves come down.

The businesses featured on this page are drawn from public business listings and ranked using their review rating and number of reviews, with a small lift given to those showing a working website and phone number. We also check each business's homepage to confirm that guttering and fascia installation is genuinely what they do day to day, which stops general builders or roofers who only occasionally touch guttering from cluttering up the results. Listings flagged as permanently closed are stripped out automatically. Where you spot a Trust Verified badge, that business has gone further and passed our full verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information. You can see exactly what that involves on our How We Verify page. Businesses without the badge haven't been through that process with us, so it's worth doing your own checks before booking.

When you're getting quotes, ask to see proof of public liability insurance and find out whether they're a member of a trade body such as FENSA or a local guild scheme, since guttering work often overlaps with fascia and soffit replacement that can affect your roofline warranty. Get at least two or three quotes in writing, ideally with a breakdown of materials (cast iron versus uPVC, for example) and labour, because prices for a straightforward semi in Harrow can vary by a few hundred pounds depending on scaffolding needs and access. It's also sensible to ask how they dispose of old guttering and whether waste removal is included, as skip hire or tip runs can otherwise get added on as an extra.
