What our clients say about us.

Jacob's knowledge is second to none, he explained everything in great detail and answered all of our questions. The work he done was first class. We definitely recommend Collett Construction for any projects that you have. We will be using Collett Construction for our future work

David P - Long Itchington
Fantastic kitchen diner knock through completed by a professional and diligent team. Always early, getting the job done and very tidy, clearing up at the end of the day. Great plastering skills also! I would highly recommend Jacob for any of your building needs

Chris Edwards-Dewey - Leamington Spa
We had Collett Construction replace a suspended timber floor with additional insulation and also replace the old ceiling joists and beams in a second room. Jacob and Gary were very professional and are certainly perfectionists in their carpentry skills. They were always punctual and cleaned/tidied after each visit and the finished floor and ceiling are fantastic. I have no hesitation in recommending them and look forward to working with them on other projects

Andy Hayden - Staverton
Collett Construction were recommended to us by a previous customer. We had already had our kitchen designed and we needed two internal walls demolished. Jacob did the project management for the whole job. He supplied all the sub-contractors who were excellent. We were extremely happy with the job from start to finish. Jacob has excellent communication skills and nothing was too much trouble. His precision and attention to detail was second to none. A first class company which I highly recommend.
