Two engineers, Fraser and Thomas, came out to my property to deal with a tricky VELFAC door issue after recent construction work on my roof. They worked tirelessly all morning to solve the issues. Now my doors work perfectly. Great professional service. Thank you guys!

Westcott installed Velfac aluminium windows, bi-folds and external doors right across our house refurb. They were friendly, responsive and knowledgeable – and explained things in terms we could easily understand. We have no hesitation in recommending Westcott.
