Extension Builder in Upper Holloway
I started working in construction sites as cleaner back in 2005 and then joined a company that was carrying out commercial renovation for licenced premises, listed buildings and offices and then moved to other companies that were carrying out domestic works, such as loft conversions, extension, renovation and everything in between. I would like to think of our company as a 1 stop shop to all your construction needs, from planning to costing, from project managing to building and delivering.

Uz Pro Construction Ltd is a London-based bathroom renovation and tiling specialist. We deliver complete bathrooms, ensuites, wetrooms and walk-in showers through one directly-managed team — no subcontracting the job out to strangers you've never met. Every project starts with a free home survey and a fixed price agreed in writing before any work begins, so there are no surprise costs once we're on site. Tiling services: wall and floor tiling to any specification — large-format porcelain, marble and stone-effect, herringbone and metro patterns, fluted and textured finishes. We tile bathrooms and kitchens alike, whether you supply your own tiles or we do, with exact quantities specified up front. We're Constructionline Gold and SSIP accredited, and every job comes with a 24-month workmanship warranty. Our last four bathroom renovations ranged from £11,500 to £16,000 and took two to four weeks on site — real figures from real completed jobs, not estimates.
