"We needed to replace our old (of 30 years) large deck with a new composite deck. Communication was key throughout the project. Either through text messages or face to face. Thanks for being professional, communicative and easy to work with. The end result, is a great deck!"

"I was very pleased with Gavin’s work, he did a great job! My deck boards were pretty bad and Gavin made sure the underneath was strong before he laid the composite floor. He arrived at my home when he said he would, he was efficient and cordial. He power washed my deck .. railings and all when done. I now have a beautiful strong deck! Thank you Gavin!"

He and his crew showed up exactly when they said they would. He was very collaborative and his communication throughout the project was excellent. It is clear that he wants his customers to be happy at the end of the day. Our HOA also hired Kevin to replace fencing for a 14 unit association and build a new enclosure for a dumpster. Again, his bids were fair and competitive and he performed quality work. I would not hesitate to recommend him."

"Costas and his team did a wonderful job on my Aunt's home. What started off as a deck repair, turned into so much more (siding, windows, new 1/2 bath). The house had been in a bit of disrepair and he was very thoughtful and thorough in his approach to bringing it back to life. My family and I will enjoy it for many years to come, and I truly appreciate some of the little things he did along the way to ensure everything was done right. He took the initiative to select things when I was not able to be there. It felt very much like he was treating as if it were his own home. His attention to detail was terrific, and he was super responsive. THANK YOU again!"
