 Trustindex verifies that the original source of the review is Google. We hired Bayside for a total home remodel. Yarden worked with us from beginning to end, from demolition to a beautiful house that I love to come home to.  He kept us informed every step of the way, guided us in choosing tasteful colors, tiles, and cabinets.  The crew worked tirelessly and were absolutely fantastic, transforming a disaster into a home.  Yarden’s vision for the project and his professionalism to make it happen went way above and beyond my expectations.  I can’t thank him enough for giving us a home we are proud of, it is gorgeous inside and out.

 Trustindex verifies that the original source of the review is Google. Complete change in our home. Tom from Bayside Home Improvement brought a beautiful renovation plan for my 1960-1970's kitchen. Some changes to the plan were made that allowed me to have a walk in pantry and increased my counter space. I walk in my new kitchen with a smile. The layout works so much better, the cabinets are beautiful, the tile work is striking, and the quartz countertops add the right touch. All the contractors were polite, helpful, and asked questions to ensure I got what I wanted.

 Trustindex verifies that the original source of the review is Google. Bayside remodeled my master bathroom and guest bathroom. They did a fantastic job! They were creative in the complete remodels, moving ever from plumbing, electrical, and walls. They helped me stay within my budget. It took 8 weeks but we took both bathrooms down to studs and moved a shower wall-so it was a large job. I would absolutely use Bayside again for my remodel.
