Diego was great to work with. Quick to respond to phone or text inquiries and very concerned with the quality of his crews work. We had very minor problem that was taken care of immediately. I highly recommend Supremax Const.

By MiguelMay 11, 2019deck painting, wood/window repair.$4,000
Unprofessional, rude and disrespectful. Overcharged estimates, missed deadlines, general lack of responsiveness and extremely poor service quality - left areas of our house damaged, and didn't care enough to check the work of his staff. When given feedback about his services, simply started rudely yelling on the phone and didn't even want to listen. Have never seen such disrespect for a customer, it was not acceptable. We will not be working with him again and don't recommend anyone engaging with this owner.

By James C.November 10, 20182nd floor, master bedroom back deck and railing repair/replacement; 1st floor back deck at wall flas$20,000Read more
We are very pleased with Supremax Construction's repairs and replacements that were made to our home. A large part of our issues were due to water intrusion into the walls of our home. I found that the company owner, Diego, has a keen eye at locating areas of concern and upon opening up those areas there was indeed damage that would become progressively worse.
Quality: Both the quality of the work and the materials used were exceptional. As an example, the original contractor of our home used untreated wood in the construction of our deck and railing. Supremax replaced deck and railing with pressure treated wood that is proven to last much longer.
Innovation: Our deck off the master bedroom was deteriorating and we have had standing water because of inadequate drainage. Supremax applied multiple layers of waterproofing materials and cantilevered the deck to provide runoff of the rain water. In addition, our basement had water intrusion from the concrete deck that came in at ground level. Supremax made a metal and concrete barrier to prevent the entry of water into our basement. At other locations within our walls there had been ant destruction to the wood and rather than putting more wood to replace it, concrete was installed. We will not have ant problems at those areas ever again.
Other character issues exhibited by Supremax was the highest level of Integrity, Cooperation, and Courtesy.
I highly recommend having Supremax as your contractor for your new or repair and replacement needs. -
By Cesar K.February 11, 2018roof replacement and fix water infiltration through the house$50,000
We had the best experience with Supremax. The team was professional from the get go to the end. We got very thorough explanation of the work to be done and reasonable explanation of the quotes. They show to be experts on detecting water infiltration on my roof and structure and very precise to hone the problematic areas, what has driven the total cost down. They showed to be resourceful on fixing the problems and avoid new ones. They showed to understand how to isolate the structure from the water, how to re-do the flashing , parts of the frame and even some pillars being less intrusive as possible. Another surprising aspect was how clean they have worked. They brought materials in according to each phase (no piling out) and removed the debris everyday, making the site look fresh every day. They have replaced our roof too in two days. The work was masterfully done, replaced the tiles for a new material, corrected all the problems and the potential ones, and it looks really great now. We feel to live in a new house ! That was a 5 start work for me and my family.

Let me start with this. Diego Costa is the nicest and the most patient person you will ever work with.
Now coming to the work he did for us. He installed pavers, synthetic turf in our backyard. He did the 12 Volt lightning work also.
Also in the front yard, he installed a water fountain(we bought it from wayfair), put pavers and synthetic turf.
The complete work done by Diego and his team is just flawless. He was very patient in implementing our ever changing requirements.
We have received lot of compliments from our neighbors. His team was very punctual and completed the work on time.
I highly recommend Supremax pavers company. Give Diego a chance to work with you. It would be the best decision of your life.
