A leading construction company in Northern VA focuses on providing optimum quality in various construction services. We take great pride in our work as we have during our 20+ years in business. Thus, you can rest assured, that no matter what construction project we handle, we will be giving nothing but highly professional and expert works. Our galleries collections of photos from previous construction projects can attest to the amount of time, thought, and effort that we put into the services we provide.

"Eco Power Works did a great job on my kitchen and bathroom renovation ! Daryl and John were very patient listening to my ideas. They brought in an architect who was reasonably priced and made suggestions to overall designs which I am so glad they did ! The project from Start to finish was on schedule which O was pleasantly surprised - these guys kept their words and their workers were always on time respectful of my property and time. I like that they always checked with me when they took major steps to double check that everyone was on the same page - they communicated every step of the way and were very careful to to do the job right. I really love the beautiful cabinets and marble countertops which were my dreams. I am so glad I hired these guys - they really did a great job overall - will definitely recommend them to my friends and neighbors !"

"Overall, our experience was positive. The pricing was very competitive, and the quality of the products met our expectations. Communication, however, could have been more consistent. Responses to our inquiries were sometimes delayed, and we occasionally received messages late at night. Additionally, working with multiple contacts made the process feel a bit disorganized at times. That said, when communication did happen, they were helpful and responsive. With a bit more coordination, this would have been a near perfect experience."

"Seddik and his crew did great work on my house addition. The constant communication and attention to detail made the evolution stress-free. We were able to move back in a week earlier than initially quoted and the final cost was within a few percent of the estimate, mostly due to additional touches we added on during the build.

"The original project I hired them for was to replace leaky faucets in both the kitchen and bathroom. Frank, the owner, was responsive and professional. They scheduled the work promptly and showed up on time. Unexpected issues were discovered that required a second trip and additional work. They communicated everything clearly and the additional costs were handled separately and transparently. They also cleaned up after the work was done. I would hire them again."
