"I needed a new house built on a complex foundation. Construction Masters did an amazing job from start to finish. Mickey and Moshe listened to everything I was looking for and worked with my vision to turn it into a reality. Their attention to sight lines and details are excellent. Mickey took me through all the work of choosing lights, cabinets, fixtures, etc. The two of them work so well together! Mickey and Moshe were there every day of the week to provide oversight on the project. The philosophy of the company is one of excellence and honesty. I do not know this because it is on a website or brochure; I know it because I had the pleasure of being their client. If they create anything, from a stair banister to a luxury bath or a whole house, it will be done to the highest standards. The work they did building the whole house was so superb that when they finished, I asked to be their client again without considering any other builders. I am going to build an ADU on the other side of my property and it will be built by Construction Masters."

"I am very pleased with the work done by Hic builders. Our initial contact was Josef. He came out and gave us a fair price to replace a wood fence, patio cover, and deck. Materials were sourced and brought in without delay despite supply shortages. My dad is a civil engineer and he noted the wood to be of good quality. He and his workers showed up daily, on-time until the project was completed. Every day the work area was left tidy and cleaned up. We live in a townhome. The only access to the backyard is through the front door and living area. His team covered our furniture and flooring. We will definitely call on Hic Builders in the future and recommend others to do the same."

"We hired MF to do an extensive remodel of our family room and backyard... Mike and his guys hit it out of the park. They gave us everything we wanted, they worked quickly and they stayed within our budget. They were flexible when we modified our requests and they were unfailingly polite and friendly. You don't expect construction on your home to go smoothly, but with MF it did. We can't thank or recommend them enough."

"Jorge, Andy and their team at A1-Builders were knowledgeable, honest, reliable and above all always available to answer any questions we had. They helped build a 2 bed 1 bath 600sqft addition to our home during the lean months over the pandemic. We had multiple projects (pool, patio, retaining wall) going on at the same time with other contractors and the crew from A1-Builders were by far the most professional. They always made sure that they left their work site clean after each dayâ s work. Jorge will definitely be the first person I call for our next home project because I know that even if he does not have the time to do the work, he will always guide me in the right direction. Thank you again to the entire A1-Builder team!"

You’re also paying for all new appliances, finishes, permits, inspections, and connections for water, gas, and electricity.
