"I’ve used Amazing Skylight on 3 separate occasions. The 1st time I had a skylight put in my kitchen, in a bathroom with no window and in a bedroom that didn’t get a lot of sunlight. Several years later I had them put a skylight in my entryway. This last time they put a new roof on my house. Each time they were both friendly and professional and best of all each time they did a great job. I will definitely use them again and with peace of mind."

"Outstanding. The job was originally estimated at one day but it soon turned into three full days. Every board that was cut and every shingle that was nailed was done in a highly professional manner. The roof is literally better than new. After raking the lawn could not come up with a single nail, the cleanup was that good. The roof itself was quoted at $5100 plus the additional plywood as needed. Another firm quoted a price including all needed plywood that was at least $500 more and did not include the finish coat of paint on the windows. The total cost was $9500 but that included an extensive amount of carpentry work (both roof plywood and window framing) at what I considered a reasonable price. An added bonus is we have enclosed gutters. The old roof the rain would bounce off the top of the gutters and could be very noisy at times, the new roof is very quiet. Roof color matches the paint scheme for the house and the installation was first rate. Price, quality, timeliness, could not have been better. Would definitely use this company again and would be happy to tell my neighbors. Two other quotes we received were higher as noted above and one couldn't supply the exact shingle color we wanted."

"John Krause Construction recently replaced my roof. I am very pleased with the quality of the work and the price we paid. Their crew was professional and courteous, and a pleasure to work with. They took extra care to clean up my entire yard and ensure I was happy with the job. I would highly recommend this company for any and all home improvement projects."

"Chevy Chase Remodeling put on a new roof on my Potomac house a couple months ago. They did a great job communicating timeline, expectations, and options up front, and then executed the job really well.  Steven and his team were all helpful and easy to work with. The offer was competitive as well. Job site was thoroughly cleaned up after. There were some minor things that needed to be addressed after the job was complete, both on the same day as well as several weeks later, and Steven and his team were able to take care of that immediately.  We love the new roof and are looking forward to many years.  Would definitely recommend to use Chevy Chase Remodeling if you need a roof."

"We had been having leaking in our ceiling near our chimney for almost a year, despite having had our roof and gutters and having our chimney flashing redone last year. After a number of frustrating follow-ups with our original roofer and chimney repair company, we called S&K, which came highly recommended on our community page. Sean came out within two weeks despite a very busy rainy season. He checked our roof and told us quite honestly that the problem was not the roof or even the flashing, which had been done well but the porousness of our older bricks. He applied some silicone sealant right then and told us to call him again if it didn't work after the heavy rains this weekend; he also mentioned we should just keep periodically reapplying this sealant ourselves. This leak has stressed us out for months and Sean was extremely honest and helpful. He didn't try to sell us any expensive repairs but was upfront about the problem. The level of professionalism, knowledge and service exhibited by Sean and everyone we spoke with is so rare nowadays; we can't recommend him or S&K highly enough."

"My husband contacted the insurance company for the claim and inspection. My husbands co-worker recommended EA Roofing and Siding. They had nothing but praise for EA Roofing and Siding.
 We called and spoke with TJ with EA Roofing and Siding  and gave him the inspectors name and number. He coordinated with  inspector. The insurance claim was approved.  The work required three separate teams of expertise which was efficiently coordinated by TJ.  
 
The roofing materials were ordered and delivered within the week of the insurance companies approval. TJ was experienced working with the insurance companies process and payment policy. The roofing workers were scheduled the next week. They showed up at 9 AM as scheduled and worked thru the day until almost 9 PM and the roof was completed. The removal of the old roof is very messy but the property was spotless when the crew left.
 The next order was for the shutter replacement and siding repair. The workers showed up on time and work was completed and again property left neat.
The next order was for interior painting and again the crew showed up at time we were told and completed the work within the day and departed with the property clean.
 We had never had to have this size of a project done before, so you are little apprehensive but working with TJ's professionalism, organizational and communication skills effected a professional, efficient and quality of workmanship. A job well done and to be proud of.

"The cleaning was done well, without damaging my middle-aged roof. Price was reasonable. The owner was prompt, perhaps too much so. (He pushed coming out the day that he responded to my request.) My only serious concern was that, after he provided an estimate for replacing another roof (my garage's), and I reached back out to him sometime later to take him up on the offer, he never responded back."
