    I had some pavers loose on my patio that needed to be fixed. George responded quickly to the quote request Yelp generated and came out to my house just as fast. He was able to power-wash the patio (driveway, and my opposite side walk/stoop) to prepare the area, then come two days later to fix the pavers. George is extremely nice and provided a competitive price. Would for sure use again when I need a new home project completed.

    After a botched plumbing job in my grandfather's 110-year-old DC row house, the upstairs bathroom was left completely unusable. The plumber left a hole in the floor where the toilet once sat. Even worse, he did not put down a tarp in the kitchen, thus allowing concrete and other debris to fall into the kitchen including the sink drain below through an existing hole in the ceiling. Thankfully I was referred to Sigma Construction Associates by a longtime coworker/friend, and what a blessing that turned out to be. When we initially met George, we were only looking to repair the bathroom floor and plumbing. But realistically, the bathroom was decades overdue for a complete upgrade and renovation. In addition to the bathroom, the kitchen was also in need of a renovation but we opted for a refresh. George listened to our wishes and was already thinking ahead with plans. Once the bathroom neared completion, water from the basement quarter bathroom started backing up into the kitchen. Fortunately, this happened before work began in the kitchen. George's crew discovered a broken pipe in the floor of the basement due to years of corrosion. This required them to not only dig up the concrete floor, but also tunnel out into the back yard to remove additional corroded pipes. Thankfully we now have reliable plumbing for years to come along with a presentable basement bathroom, a refreshed kitchen and a 21st century upstairs bathroom! What George and his crew do is more than just improving the aesthetics and functionality of your home. George loves what he does, and it shines through. He is patient, a good listener and very personable. He thinks ahead for what will work best in your life while keeping the final cost affordable and reasonable. He is truly a blessing and a godsend who is fair, genuine and trustworthy. The added bonus is that he has a hardworking, talented crew who takes pride in their work as well. If you have the opportunity to hire/work with Sigma Construction Associates and George Barksdale, I highly encourage you to do so. My grandfather is quite the curmudgeon but after the results, he is now inspired to hire Sigma for other home projects.

    Sigma Construction Partners renovated my townhouse which included painting my 3 levels including closets, new basement floor, and they gutted out the bathroom with a tub and rebuilt a shower. Their prices were the cheapest, but the quality of work was impressive. They demonstrated professionalism, the body of work past my expectations and it also reflected what I requested. I will use them for all my future projects, having a reliable contractor you trust that is reliable and not trying to add on unnecessary cost is a blessing. I would definitely recommend their services.

    Ben help me get new roof, assisted on contacting my insurance to coordinate and pay for the roof…read more Only knock one star since scheduling was pain and took awhile to get rest of the project done.

    A rep from RoofER knocked on my door and asked to examine my roof for storm damage. I had just…read morereturned from a long shopping experience, was tired and just told him, Sure--go ahead. He examined and told me that he had found storm damage and that I should notify my insurance company, which I did. My last roof was installed in 2010, so I thought, well maybe I do need a new roof although I hadn't experienced any leakage. Insurance adjuster came out, agreed there was damage and approved roof replacement. A few days after the crew arrived at 6:00 a.m. to replace roof. HOA rules are that work should not start before 8:00 a.m. but they insisted they needed to get the work done in one day. I had no communication with them while they installed and only learned after a few days that they had replaced 33 plywood sheets for the cost of $3300 extra. Every few days I would receive another invoice for an additional amount. Another $8,000 for flashing, another couple thousand for clean up. Over the course of a couple weeks I would receive another invoice for a greater amount. It was the most frustrating experience I'd ever had with a contractor. Luckily, my insurance company was generous and covered the cost. I am an elderly widow, this was definitely outside my skillset--lesson learned. I hope they did a good job with the roof--but I cannot see the top! I cannot give them a 5 star rating because of the lack of communication and the confusion in the billing process. If I did not have a good insurance company, I do believe it could have been a financial disaster for me as I am living on a fixed income.
