"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."

"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."

"After researching and obtaining quotes from a number of companies, I selected The Fifth Fuel to air seal and insulate my attic (blown-in cellulose), cantilevers, and rim-joist. From the initial consultation with Adam to email follow-up, the project and my options were clearly explained. When I asked about putting a higher R-value in my attic, Adam provided the price but explained why it didn't make sense for me. I appreciated that he didn't try to oversell me. The proposal laid out everything they would be doing. The cost was reasonable. It wasn't the lowest bid, but was less than 50% of some other bids. The day of installation, the crew arrived a bit early. Throughout the install they were professional, kind, and clean. They protected the inside and outside of our house and vacuumed afterward. They conducted a blower door test at the end to quantify the difference made by air sealing. Within two hours of them leaving, we've already noticed a difference in our comfort and our A/C is not even running half the time it was before."

"We had a great experience with Discount Energy Services. They insulated our entire attic and crawl space, and from start to finish they were professional, responsive, and easy to work with. The turnaround time was impressively quick, the quality of the work was excellent, and we felt the value was very good for the scope of the project. The team was efficient, knowledgeable, and clearly took pride in doing the job well. We really appreciated how smoothly the whole process went and would gladly recommend Discount Energy Services to anyone looking for high-quality insulation work."

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."

"Kelvin, the owner of the business, did a fantastic job with my project. He answered my call, was able to come by to look at the project promptly, knew exactly what I needed done, and made this process very easy with a reasonable quote as well. I had plywood flooring down and he and his guys unscrewed it, moved my attic items around to get full access in stages and sucked out all the old insulation, while covering my stairs and hallways with drop cloths. They were clean, respectful, efficient, showed me what was happening along the way, and did a stellar job. They added foam insulation and blown-in insulation, reinstalled my flooring and left the job in very good condition. I am very happy to recommend them!"

"Good. Thad from Evergreen Electric could not assist us with our electrical problem, our electrical company will need to resolve it but he did tell us what was wrong so when we called the electric company we could tell them exactly what they needed to do for us.

FAQs for spray foam insulation projects in Warrenton, 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.
