"David and his team were very professional and the work they did was excellent---we could tell the difference the next day. The temperature on the 2nd floor is several degree lower than before due to the new insulation and feels much more comfortable. David has solid knowledge regarding insulation and he explains things clearly. Definitely would recommend David and Prudent Homes to my friends and neighbors."

"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."

"Jeff and his crew were great to work with. They re-insulated my attic and did an excellent job at a fair price. I highly recommend them and would happily hire them again for other work on my home. 10 out of 10."

"pleased with the new insulation in my crawl space, any place where a rodent could possibly be entering my crawl space was fixed with foam seal. The crew was efficient and were care of not making a mess when removing the old insulation. I am very happy with this contractor. fully recommend as another contractor came in seemed to make up problems that were not there. For instance a leak that was not there. trust Mark at DMV as he is honest and knowledgeable of the products he sells and I having him back for a estimate to do my attic."

"Exceptional work. Founders spray-foamed my two crawl spaces in November 2023. These guys are super professional and efficient. From my initial call to the consultation to the actual job completion was about 2 weeks. The pricing is the best I found after getting three other quotes in the Arlington, VA area."

"Louis and his partner we very professional and thorough. They initially put down drop cloths to protect our floors and nearby items. The precisely installed the insulation to match up with what was already on the walls. I had 1 area that we could not clear out completely due to some heavy shelving, and they worked around the shelving and still did a great job. They ensured the new insulation was mounted correctly and attached well with the insulation that was already on the wall. They also fixed up with tape some adjacent pieces of insulation to make it look much neater. When they were finished to thoroughly cleaned up where they had performed the work. I am very satisfied with their work, They did a great job. Thank you"

"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."

"Removed/replaced blown attic insulation, foam sealed and treated. placed batts over lights, fans, around attic access, installed access blanket. Responded to my request for cellulose despite preferences otherwise. Bill and assistant are a pleasure to deal with totally. They arrived on time and completed the task in less than 8 hours at a better price than half-dozen others."

"I got my attic insulation replaced with them, and I’m very happy with the service. The team was clean, professional and got the job done quickly. Before the project, the upstairs was always freezing in the winter, but now the temperature is consistent across all floors.I definitely recommend them!"

FAQs for spray foam insulation projects in Triangle, VA

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
