"Very professional. Arrived on time to install a garage door opener. I had a chicken coop that needed to be assembled and he agreed when this wasn’t what he was hired for. Not only that but he replaced a rotted broken door on another chicken coop! I would definitely recommend Better Dayz!"

"Dennis was more like a zen interior construction contractor/laborer. He uses an extremely competent crew. Repaired far more than the little box of “work done” above. Ceiling repair in three rooms, plaster repair of interior walls, door hardware replaced, carpeting removal, complete renovation of a deteriorated bathroom, including shower demolition and tile laying. He explained the costs thoroughly, what needed to be done to get my beloved home of 32 years ready for selling. Very sensible and sensitive to my situation. He was efficient, and recommended only necessary work, saving me money. He has a long history of restoring properties in his native Rhode Island. I am very pleased with the results. Hope I’m lucky enough to find this level of excellence in Buffalo!"

"They did a fantastic job replacing some rotten molding around my back door. They replaced multiple boards on my back deck and stained my deck with two coats of stain. In addition they painted my back door inside and out. They completed all the work in less than a week. I would highly recommend Christine at Poseidon contacting."

"Jon did an excellent job of transforming our outdated, broken bathroom into one that is in showroom condition. The bathroom required more work and time than anticipated and he was at our house everyday putting it all back together. We will have Jon return to our house for future jobs and we highly recommend him for any project that you are considering. Most importantly, Jon listens to and respects women. If there is a problem he will offer solutions/alternatives."
