Local review — Uxbridge

★★★★★
“We have recently had our double storey extension built by AMH in Uxbridge. An amazing job done by an amazing team, thanks AMH for all the work. A really friendly team who work exceptionally hard and most importantly fast. We lived in our property throughout our renovations and the team were exceptional in ensuring cleanliness and protecting the rest of the house from dust and dirt. Will be calling them back for future work.”
