"Between Brad K., the company’s support team, and the crews who come out to do the job and execute the work, you cannot select a better company to help you make your home energy efficient and reduce your utility bills by insulating the house and sealing your duct work. As for Brad K., the job begins with Brad coming to your house and conducting an Energy Audit. This gives everyone a far better understanding as to what needs to be done in your home. And, Brad concludes with conducting a “ Test Out,“ to see the improvements. Pepco will offer you a partial rebate for the work completed and they are very satisfied with a 20% reduction. As for us, we hammered Brad with dozens of questions over the course of time before and after we ratified an agreement. In every case, Brad was extraordinarily responsive especially with him being burdened performing audits throughout the day and being offsite. We couldn’t be happier with Brad’s performance. The same goes for the inside team including Jeff, Gordon and Ashley. And, everyone of the guys and their team leads who came to the house not only focused on executing their expertise, but were also very customer focused. In our case, the “test out demonstrated a 36% reduction,“ and Brad believes the partial rebate will be even greater. A Little Constructive Feedback Here: Be sure to ask and fully understand what needs to be done prior to the crews arriving. We had three teams over three days (not in a row) and learned at that moment what more needed to be done to fully finish the job. This will minimize to virtually eliminate any further challenges for the crews and yourselves. However, the job was completed. Over the next 45 days or so, after our utility bill fully cycles, we look forward to seeing the results of Atlas’s work and the reduction in our utility bills. Atlas Home Energy Solutions is Your Best Buy. We are certainly available to provide any further references. RichandJames Peterson Silver Spring, MD (301) 592-1616 Email: [email protected]"

"I had several options to pursue in finding a remedy for my hot attic. After meeting with the insulation consultant who was extremely knowledgeable, patient, and provided detailed explanations of how to insulate I knew proceeding with the job was the right decision. My attic is noticeably cooler and I highly recommend"

"I hired Atlas Home Energy Solutions to remove old insulation and replace it with the foam technique. However, I ran into numerous unexpected problems due to a slow leak from old pipes. It took awhile to sort out. Atlas Home Energy Solutions gave me lots of expert advice. They were willing to come out and review the situation. They were also willing to reschedule and wait until another contractor dealt with the water issue and its ensuing problems. They helped me make some difficult decisions before they could insulate the crawl space. When it was ready for them to come and insulate the area they bumped their schedule forward to get it done. This company did sterling work. Their expertise and professionalism were outstanding. They really know what they are doing and guided me through a more protracted process than originally envisioned. I would highly recommend them to anyone."

"My house is a little wacky and the proposal was to include all of the crawl space and ceiling surface area. Sadly there was no way to know that a portion of both were inaccessible to insulate. Was hoping to fix issues with freezing pipes by insulating but that is the part they could not access. The scheduling and some staff on the phone is a little dry on the phone. The crew who came to do the job worked their butt off and were super nice. CJ, who drew our proposal, was very nice and knowledgeable. He warned me that his estimation might be a little off but the estimation of the Pepco energy saving percentage back ended up being way off after the energy audit. That made the job much more costly than predicted and I had not planned for that. He was willing to adjust the bill slightly but not significantly enough to really make a difference. Overall, it is going to make a huge difference in the comfort in the house and the crew was very professional."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation questions, answered by experts

Yes, PEX pipes should be insulated in certain situations. While insulation is not always necessary for pipes running through insulated interior or external walls, it is recommended for any pipes located in uninsulated rooms, unheated areas, or outside, especially in regions with cold winters. The primary reason is to prevent freezing. Although PEX is more resistant to cracking from freezing than other materials, repeated freezing and thawing can weaken the pipes over time, increasing the risk of a burst.

Heavily exceeding building code requirements for insulation not only wastes money on materials but can also lead to ventilation and moisture problems. In most cases, the minimum amount of insulation required by code is perfectly adequate.

On average, insulating an attic costs about $2,500, with a typical range of $1,500 to $3,500. The final price often depends on the attic's size, with costs generally falling between $1 to $3 per square foot. For example, insulating a 1,800-square-foot attic would likely cost between $1,800 and $5,400.

If the project involves removing old insulation, this can add an average of $900 to the total cost, bringing a full removal and reinsulation project to around $3,000.

Several factors influence the overall cost:

  • Insulation Type: Prices per square foot vary significantly by material.

  • Reflective: $0.50–$1.50

  • Blown-in: $1–$4

  • Batt: $2–$4

  • Loose-fill: $2–$5

  • Spray foam: $2–$5

  • Structural insulated panels (SIPs): $4–$7

  • Project Complexity: Factors like sealing air leaks, poor attic accessibility, and required inspections can add to the cost.

  • Removal Issues: The discovery of mold, asbestos, or pests during the removal of old insulation can substantially increase the price.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

A-frame houses pose specific challenges that can make heating difficult. Their open concept design with high ceilings can lead to a colder lower floor and a warmer upper floor. A ceiling fan that pushes warm air down or pulls cold air up, depending on the season, can easily counteract temperature issues. Additionally, certain types of heating do better in these homes than others. For example, heated floors tend to be more practical and energy efficient than baseboard heating.
