"Clean Tech Construction was terrific! The team arrived slightly before the scheduled time, removed the old, poorer quality insulation, installed new insulation, including areas that a previous company had not been able to reach, and cleaned up everything before they left for the day. When I initially contacted them about the work, they answered my phone calls within 15 minutes and continued to respond to any calls/questions quickly and politely. I would hire them again in a heartbeat."

"Robert Pino and his brother were amazing not only did they do an impecable job building the shed but he also helps do another project redoing the bathtrom in the house. He was very responsive and fast about scheduling us in. I highly recommend them for future projects"

"We are extremely happy with our new roof. The crew manager Jeremy was diligent about how things were going and done. He answered any and all questions we had. His crew worked extremely hard in extreme heat. We don’t have any trees near our roof so they were in the sun all day. They never slowed down they kept a steady pace. They were at our home 2 days, they worked cash a team to complete the job and the clean up was done with precision each day. People going by we’re impressed with the professionalism of your company and of an amazing job. One of our neighbors is interested in your company doing his roof. We would highly recommend your company. Our new roof makes our house stand out in the neighborhood. Thank you Jeremy and Crew"

"I discovered WS Builders Corp through Angie's List while searching for a contractor to renovate our family room. Our project involved modernizing a space dominated by an outdated brick wood-burning fireplace and 1980s-style built-ins. We aimed to transform it with a horizontal electric fireplace, custom fluted built-ins for the TV, hidden shelving for electronics, and stylish open shelving with LED lighting. Prior quotes from other contractors seemed inflated, but when I connected with Wladimir from WS Builders, he provided a fair estimate that aligned perfectly with my expectations and the materials' costs. We promptly signed the contract, and work began without delay. Wladimir estimated about 35 days for completion, and impressively, the team finished in just 30 days despite some minor design tweaks along the way. The craftsmanship displayed by Jose, Wladimir's masterful carpenter, was nothing short of exceptional. He meticulously crafted everything from drawers to shelves to the elegant fluted details above the fireplace, transforming our wall into a true work of art. Jorge, the electrician, skillfully installed the LED lighting and concealed all cables behind the TV, maintaining a clean and polished look throughout. The painter ensured a flawless finish, meticulously covering the ceiling, walls, and newly installed shelves. The transformation from the initial state to the finished result is remarkable; even my 18-year-old son commented that it resembles a page out of a design magazine, and I wholeheartedly agree. I extend my deepest gratitude to Wladimir and his team for not only bringing my vision to life but surpassing all expectations. Their professionalism, attention to detail, and commitment to quality craftsmanship are unparalleled. Encouraged by their exceptional work, we promptly engaged WS Builders for a deck project following the family room renovation. I confidently recommend WS Builders Corp to anyone seeking superior craftsmanship at a fair price and delivered precisely on schedule. Wladimir's responsiveness and clear communication throughout the project further underscore their reliability and commitment to customer satisfaction. I eagerly look forward to collaborating with WS Builders on future projects and have no doubt in recommending them as a company you can trust for outstanding results."

"I just want to say that they were prompt, neat and professional as well as friendly and understanding. They were one of my blessings for the day. I will be looking to them to help me with more of the projects I have around the house. I will certainly be recommending them to friends."
