The quality of John’s work exceeded our expectations

We hired John Kenny Construction to do our home renovation. John Denneen was the person we worked closely with during the construction process, which consisted of adding 2 bedrooms and 1 bathroom over 3 car garage (approx. 700 square feet), redesigning kitchen, replacing all cabinets, appliances, flooring, granite counter tops, back splash, moving walls to create new wine bar with granite counter top & cabinets, replacing tile floors with wood & stripping existing wood floors to match new wood floors, and replacing concrete driveway with pavers. John advised us it would take 3 months to complete the renovation. We were skeptical, as other contractors stated it would take 5 to 6 months. We expressed concern as we were renting a house during the renovation and needed to know the "real time frame". John assured us we were on schedule for the 3 month completion. And he was right ... Not only was the job done on budget, it was finished 1 week early! In addition to our renovation being on time and on budget, the quality of John's work exceeded our expectations. Any of our future home construction or renovation work will be done by John Denneen.

Can-Do Attitude

Denneen Construction built our custom Jax Beach home in 2018. John’s hands on style and can-do attitude makes nearly anything you can think of possible and then come to life. John has cultivated a well-deserved reputation with his professional group of subs and others that are intimately involved in the process. One thing you will get tired of hearing when speaking to others about Denneen Construction is how much they LOVED to work with John and what a FANTASTIC guy he is...fortunately I must agree!
