"If I could give this company a 6 out of 5 stars I would! They did a fantastic job overhauling my mother's deck, back patio, fencing, and front portico. All of the work was absolutely essential for safety and structural reasons, and I'm so glad I chose OSSA to do the work. My mother has Alzheimer's, which presented additional issues, but the entire crew was incredibly kind, respectful, and understanding of the unique challenges they faced. They were responsive and kept me aware of everything regarding the job along the way. My mother is so pleased, and I have the peace of mind that all of her outdoor space is safe, beautiful, and accessible. I will be hiring OSSA to do some work in my own home, as I look to make necessary improvements in the future. I've told everyone I know how how wonderful they are. 6 out of 5 stars!"

"Had an upper and lower deck installed off of the back door. While getting estimates, Nick (Steadfast) was the only company to show up with trex samples. I live out of state and had tenants in the home and they worked on my preferred schedule. Took 5 days as promised. Easy to work with and very happy with the outcome."

"The guys at Z and O Construction did a really nice job of replacing my back deck! The company owner, Oral Aydogdu, was very knowledgeable and helpful when explaining the work to be done. His Crew Chief, a gentleman named Lazarov, was a real master at building and fabricating things, and each of the guys on the crew was a solid professional. It was a pleasure having them around, watching them work, and learning some of their tricks and techniques for doing things! These guys did a beautiful job of replacing my deck, and bringing it up to current Fairfax County codes. This new deck is much better and stronger than the old deck was, and should last for many years!"

"We write this review as a sigh of relief now that our renovation project with River View is finally complete. The quality of the final work is excellent, and the construction crew, architect, and county inspector were all great to work with. The original crew we worked with, led by Edwin, were so hardworking, friendly, thorough, and fast. That's what really pushed us from 2 to 3 stars. However, the process getting here was frustrating and unnecessarily chaotic. Timeline & Communication Issues: Initial promise: We were clear that the renovation had to allow us to live in our home during construction and be completed before Christmas. Early communication: Our original project manager, Cris, was personable, and early communication seemed fine, if a bit informal and sometimes inappropriately personal. Major miscommunication: Near the holidays, we discovered that the plans submitted included cutting into the roof — something we explicitly said we didn’t want. This contradicted verbal assurances and caused major last-minute changes. Project Management Failures: Poor planning and oversight: Cris and the architect’s plan didn’t align with the construction work. We had to get involved directly with the county to fix errors. Paperwork errors: Incorrect submissions to the county added delays and confusion, which we had to monitor ourselves. Last-minute scramble: We were cleaning up dust on Christmas Eve due to these planning failures. Personnel Turnover & Lack of Handoff: Cris leaves the company: No proper handover to James, the new PM, who was unfamiliar with our project. Crew replaced: The original crew, who were great, were gone; new crew had no context or direction. James leaves: Another handoff with no context — the third PM had no idea about our project or its outstanding items. Escalation mishandled: When we raised our concerns with Kyle, the CEO, the response felt dismissive, with no accountability for the previous missteps. In summary, it's a beautiful end result... but we’re glad it’s over. The process left us frustrated, confused, and frankly, exhausted."

"We are extremely pleased with our lovely patio which was built by Nelson almost a decade ago. From the start it was executed properly from a beautiful design, grading away from house, putting a sturdy, non-destructible base with layers of gravel and stone and then the beautiful papers. Nelson, a truly skilled mason and professional, was reliable, efficient and methodical in completing the project for us on time and within budget. The recent patio refurbishment refreshed the patio and made it look brand new again. I highly recommend AVEC."

"Great to work with, reasonably priced and performed high quality work. Will hire again for other projects."

"Thomas M was an excellent technician and did great work fixing all the basement windows around the house. These windows are difficult to find a replacement but he was able to repair and repaint them. The other technician was Pablo He worked on caulking all the windows around the house and he did some filling work on the garage sliding doors You did a good job, but Pablo left his trash around and didn’t pick up after himself so Thomas M and I did that on the third day. It took three days total, but it was two men for two days and one man for a 3/4 of a day actually. Although I’ll probably get charged for a full day, since it went past noon. The labor portion is the most expensive and a little higher than I initially anticipated. So, I was hoping for a quicker turnaround, but overall quality work was completed. I would highly recommend Thomas M as a technician to do future work. He’s very knowledgeable, friendly and does a great job. I would hire again but include more details in the contract language."

"We noticed a significant hole developing in our shared alleyway, which seemed to worsen quickly. Also there were other depressions in our driveway where the asphalt was on the verge of giving way. After trying to contact multiple contractors and leaving several voicemails, the only one who responded promptly was Patrick from Capitol Hill Masonry. He came out immediately to assess the issues and provided us with a quote without delay. Once we approved the work, his team began the project the same day and completed everything by the following day. We are extremely pleased with the quality of their work. Patrick and his team were friendly and took the time to patiently answer all our questions. I would highly recommend Capitol Hill Masonry to anyone in need of masonry services."
