 Trustindex verifies that the original source of the review is Google. I hired Sam from Bayside Home Improvement for a full bathroom remodel. He gutted my bathroom, moved plumbing, repositioned the vanity and toilet, put in new installation and Sheetrock, added recess lights, installed a new window, and did the tile work from floor to ceiling. I absolutely love the results! The tile work was done perfectly, and the grout lines were neat and even. Sam and his crew were meticulously clean, thorough, punctual, and attentive to our needs. I ‏referred Sam to my family and friends, and he has done great work for them too! I would give him 10 stars if I could. Highly recommend!

 Trustindex verifies that the original source of the review is Google. Hired these guys to redo our old kitchen and bathrooms after meeting with several contractors, I found on Google and other sites. Avi did a great job explaining the process and did a great job on the design and preparation, which made the work a lot easier. Working with him and his design team really turned out to be a good experience for us.
They handled everything from getting the permits to passing inspections, and all the coordination in between. The communication throughout the process was always clear and consistent which gave us a great sense of comfort. After all their finishing work looks excellent and we will be looking forward to hiring them again next year for our exterior projects. Thank you!

 Trustindex verifies that the original source of the review is Google. I am very happy with the complete bathroom remodel. It was an old and not very modern bathroom, I wanted to change it completely so I hired this company to help.

Sam and his team did a wonderful job, they used modern design materials and did an excellent job putting it all together.  If you are going to carry out remodeling, I always recommend them ????????
