"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."

"I contacted Atlas not because of high energy bills but because of noticeable summertime temperature differences between the first and second floors. My home is 32 years old and had never had the ducts cleaned and I suspected there was leakage from seams in the duct work. While the house was built to the then current (1988) code levels, the code is now more stringent. For example, my attic insulation was R30 where code is now R50. Atlas first performed an energy audit. Based upon that outcome, they recommended: (1) rerouting the bathroom exhaust fans through the roof, (2) additional insulation in the attic bringing it to R50. (3) closed cell foam sealing in the main and garage attics where appropriate, (4) cleaning the heating/cooling ducts and (5) using the AeroSeal product in the same ducts. I opted for all of these services. The work was spread over 3 occasions, each no more than 2 days duration with most completed in a single day. Their friendly work crews were very attentive to my property, made sure to put down drop cloths throughout the house and generally made certain everything was clean upon leaving. They kept me informed throughout every task and showed/explained what they had encountered. My ducts certainly did need cleaning, even though it’s always been a smoke free home environment and without pets. The benefits of this work have been fantastic. The AeroSeal process yielded a 98% reduction in duct leakage. I can tell very little temperature difference between the first and second floors now. I’m expecting more noticeable improvements during the winter months. I strongly without reservation recommend Atlas Home Energy Solutions."

Insulation questions, answered by experts

The success of insulation projects in Frederick depends on choosing materials suited to the local climate, ensuring proper air sealing, and achieving recommended attic R-values for MD. Addressing moisture control and eliminating thermal bridging are essential for long-term performance. Hiring experienced local professionals familiar with Frederick’s home styles and weather patterns helps ensure your insulation remains effective and energy efficient.

Helpful?

Frederick homeowners should inspect insulation each spring for signs of moisture or ice dam damage in attics and basements. In summer, check attic temperatures and monitor for high cooling costs. Fall is ideal for energy audits and confirming insulation depth before colder months. During winter, watch for frost in attics and spikes in heating bills. Regularly reviewing utility statements and inspecting crawl spaces helps catch issues early.

Helpful?

Combining insulation with upgrades like air sealing, HVAC improvements, or roof work in Frederick can boost energy efficiency and streamline scheduling. Many local contractors offer bundled services, making it easier to coordinate projects. Completing multiple upgrades together also helps your home better handle Frederick’s seasonal temperature swings and may qualify you for utility rebates or financing options to maximize long-term savings.

Helpful?

In Frederick, signs that it’s time for insulation service include rising energy bills, rooms that feel drafty or uncomfortable, and temperature differences between floors. Homes built before 1980 in Frederick often lack modern attic insulation, making them more prone to heat loss. If you see condensation or moisture in your attic or basement, or your HVAC system runs frequently, it’s wise to schedule an inspection.

Helpful?

In Frederick, insulation projects may reveal hidden issues such as outdated wiring, the need for mold remediation, or pest infestations in attics and crawl spaces. Homeowners sometimes encounter costs for removing old insulation, installing vapor barriers, or improving attic ventilation. Permit fees and creating better attic access can also add to the project. These factors are especially common in older Frederick homes with unique layouts.
