House Extensions across Penketh (WA5)
Blades Building — a Warrington-based Ltd company covering Penketh and the wider Cheshire area. Rated 10/10 on Checkatrade across 36 reviews.
We do a lot of house extensions in Penketh. The pattern in WA5 tends to be single-storey rear kitchen-diner extensions — often part of a wider layout change rather than a standalone job — and being a small Ltd company means the same team is on site from strip-out through to hand-over, not a rotating crew of subs.

What we typically specify for Penketh jobs
Penketh house extensions — questions we're asked
Can you match the brickwork on older Penketh homes?
Yes. On period stock around Fiddlers Ferry Marina we source reclaimed facings and colour-match mortar so the new wall reads as part of the original elevation, not an obvious add-on.
Do I need a Party Wall agreement in Penketh?
If the extension sits on or within 3m of a shared boundary — common on the semis and terraces around Great Sankey and Cuerdley — a Party Wall notice is required. We can point you at surveyors we've worked with.
