"We were 100% satisfied with Washingtonian and with their work building our addition and deck. Not only was the workmanship and quality of the construction outstanding, but they operated with honesty and integrity. Their goal was our satisfaction and building a quality addition and deck. They accomplished all three and were reliable, dependable and conscientious. At no time did we believe that they had over-committed or were unable to deliver on what they had promised. They never cut corners to rush to another job nor did I ever feel that they were not spending the necessary time to ensure that the work on our job was thorough and complete. Travis, Kris and their crew were 100% professional, communicative and transparent. We will be using Washingtonian again, without hesitation. Our experience was excellent and they did an awesome job."

"Home Genius Exteriors is an outstanding organization! They told me what time the crew would be here and they were true to their word! They showed at 7am this morning to get right to work! They tore off the roof completely to diagnose the damage from the previous roof and replaced the necessary plywood that was damaged. The crew was very kind and professional! They were very neat and through out the whole process and by the end of it all the clean up was immaculate! Mr. Clemons, the sales rep, was very helpful, thorough and kind! He helped me understand the cost of everything and made it make sense to replace the entire roof as well as my gutters! The project manager Angel Martinez, was super helpful throughout the project, he helped me understand any extra costs and also helped me save where it was possible. He was very attentive and responsive! I recommend Home Genius Exteriors to any and all looking for home improvements!"

"Very disappointing. The firm was very late in its installation work - months after it promised. Its anaylsis of our gutters was unreliable. and its responsiveness in correcting its work was slow and required multiple calls and emails."

"Spent ~$50,000 on a new roof with them. Thought everything went well. Years later discovered that they had not sealed the cricket on the chimney well enough. Discovered water coming in and eventually rotting the wallboard, studs, etc. Had to replace entire wall. Called them about the issue, they sent a rep. He said it was the chimney's fault, it was leaking. Not so, opened the wall and ceiling and had another roofer come spray water on the chimney, nothing, no leak. Then sprayed water on the cricket, water came in. Exterior Medics would not admit any fault. Had it repaired, no leak, no problem since then. Had recommended to a friend, never gain, he also had a bad experience. DO NOT USE IF YOU WANT QUALITY WORK AND A COMPANY HAT STANDS BEHIND THEIR WORK."
