"I have to restrain myself from going overboard recommending Northern Virginia Insulation. Of the responses supplied by Angie's List, NoVa Insulation was able to schedule the first in-home appointment. They asked for a half hour to assess the opportunity. (Another company wanted to set up a 2-hour appointment with both owners present, which looked too much like an invitation to a sales pitch, so we passed on them.) Jeff, the owner, arrived when expected, took only as much time as he needed to gauge the materials and effort involved and work up a quote. He was pleasant, focused and professional, providing a price without pressure or drama. His crew was able to perform the work within a week, arriving on time and taking extraordinary care to avoid damage or leaving debris. All-in-all the experience was first-rate, from responsiveness, to price (best of all the quotes), to quality of work. If you can get them, do so. Highly recommended!"

"After my call to Discount Energy Services, I knew who was coming and when to evaluate my attic insulation. The estimate was prepared on-site with pricing. The workers arrived and knew exactly what they were to accomplish, which they confirmed with me. They prepared the entire path with clean drop cloths and created a plastic drape around my attic stairs. The foreman was glad to explain any aspect of the procedure. My attic was upgraded to R-49 and the difference is notable."

"Superb from start to finish! Installed baffles and an additional 10"+ of blown insulation in our attic. Crew arrived on time, protected all the areas, and did a superb cleanup afterwards. The two crew members were outstanding...and very professional at all times. I would recommend them to anyone! Bob C in Burke, VA"

"David Sampson of Prudent Homes did an amazing job, I could immediately tell the difference in temperature in the garage and our two pantries where Dave applied blown-in insulation directly above. He made sure to protect all soffits and recessed light fixtures. He also applied insulation around the attic opening and cover. The price Dave charged was well less than a competitor, and Dave was much more thorough in his initial assessment. Dave and his worker made sure to clean up where needed. I highly recommend Dave and Prudent Homes, and will definitely use them again for future insulation needs."

"From initial contact with their sales department we've had a great experience, Corey did an excellent job of taking pictures and showing the problems in our attic. Their level of communication from emails to phone calls was precisely correct by contacting me when needed and not too much with pictures detailing each solution and its associated cost. On the first work day their crew called ahead of time, arrived promptly and came prepared with masks, plastic sheeting, full body outfits and cloth covering for the stairs. In just over 6 hours they had cleaned up the entire attic removing bad sub-floor and other insulation, laid out the foundation for building a large deck space and placed part of the first layer of materials down. They also sealed the attic door along with some of the air vents and ceiling fans. They completed insulating my front porch overhang and cleaned up all of their mess very well. Painters tape was used on corners where they we’re most likely to bump into it for protection and plastic sheeting was setup precisely where needed to keep dust off of our hallway things next to the attic entrance. Overall it was a great first day and they even spotted an issue from a previous vendor who failed to properly connect some of their duct work together (which was the original cause of my daughter’s room temperature being so hard to control the temperature and not easy to spot). The only complaint I have is that while I fully expected the need to finish our attic sub-floor, remaining layers of TruSoftTM Cellulose on the main floor and encapsulate the duct lines with Polyurethane Spray Foam all before finishing with blown-in insulation, they left a key piece incomplete. When leaving they left the duct work leading from our main trunk line to my daughter’s room off. This left a hole in the main trunk line reducing heat in all upstairs rooms but most important is that nothing was connected to my daughter’s room. So around 6:00am she woke up coughing as we noticed the upstairs was around 56 degrees. Overall a simple heads up would have solved everything as we have space heaters, however I did not look into the attic when they left so that’s my fault for not knowing a key piece of the duct line was missing. Based on the overall work complete I would still very much recommend them as Robert (onsite team lead) was very good at communicating and the crew we’re all quite friendly. Their work will last for the lifetime of my house and has already added value to the sale price. In the end they made a really nice attic deck leaving me with plenty of useable storage space. While this is not the cheapest company, the quality and knowledge that I never need to worry about my attic again is certainly worth it."

"From the start of the estimate with Jon to the insulation project with the Team Leader Carlos, the project went well as expected. Jon was very professional and knowledgeable. He did not try to up-sale services I did not need, and I appreciate his honesty. Jon went over the appropriate insulation for the attic and the garage ceiling to bring our home to a comfortable level. Carlos and his crew did a great job communicating with me while performing the insulation. Carlos immediately notified me of a leak he discovered from the attic fan and temporarily paused the work on the attic and moved to the garage ceiling insulation while I addressed the leak. As a customer, the only comments/suggestions I would give to the crew is: (1) make sure they keep their tools and materials off the lawn (2) make sure the plastic wraps from the materials they use and trash does not get blown away to the neighbor's yard/driveway, and finally, (3) ask the homeowner which bathroom the crew can use while on-site. Overall, I am very happy with Comfenergy and their service. In fact, I have already recommended them to a curious neighbor."
