Professional and reliable building company. You can trust them to get on with the job whilst you are out. All employees polite and courteous. They have done a number of renovations at my home, restored bay window, replaced extension roof, new lounge ceiling and fitted new windows at rear of property. I would highly recommend to anyone wanting building work completing to a high standard. Thank you Lee and Team

Ultrabuild was an amazing company to deal with for our House Extension on the outskirts of Harrogate! I'd highly recommend Ultrabuild and the team not only for a good price but an amazing finish!

I am the proud owner of a beautiful new porch although I’m not sure I’m doing it justice! Lee and his crew were brilliant, from the very detailed quote to the cleaning up after themselves every night. The end result is perfect and workmanship excellent. Highly recommend

Had an extension built by ultrabuild, and have to say we are absolutely thrilled by the out come. Was better than we'd even hoped for. Great set of lads too. Would highly recommend.

The Ultrabuild team have worked on our house a couple of times, they built an extension and constructed a new kitchen, both times their attention to detail has been fantastic. Their workmanship is brilliant and they are always clean and tidy; such a pleasure to have them in our home. Would definitely recommend.
