Customer Satisfaction is our number one priority and we promise that we can make a real impact in your home in a way that keeps you happy every step of the way.

"Atlas home energy solutions did an outstanding job from start to finish. They were professional, knowledgeable, courteous and easy to work with. All the crew members Ben Mott (was very knowledgeable, did the home energy audit, followed up with competitive quotes, which was adjusted to accommodate my request, offered BGE rebates upfront, patient and friendly to attend my calls and answer all the questions), Zam (Crew leader who did the exhaust fan installation), Tun (Crew leader who did an outstanding job to insulate the attic and basement), David (Crew leader who did duct cleaning and Aeroseal) were phenomenal and did an outstanding job. The end result is a day and night difference before and after the work and my BGE bill last month went down by more than $100 which is a huge cost saver. The HVAC does not run that much these days and the temperature is pretty even across the 30-year townhouse. I highly recommend Atlas home energy solutions for home energy audit and improvements."

Insulation installs or upgrades FAQs

Yes, insulating an unfinished basement delivers meaningful benefits even if you don't plan to finish the space. Proper insulation reduces heat transfer through basement walls, which can account for up to 30% of a home's total energy loss. 

This improvement enhances comfort throughout your home while potentially reducing energy costs. Insulation also helps manage moisture levels, protecting your home's structure and improving indoor air quality.

Rigid foam board and spray foam insulation provide superior moisture resistance for basement applications. These materials create effective vapor barriers while delivering high R-values per inch of thickness. Rigid foam boards resist water absorption and can withstand occasional dampness, while spray foam creates an airtight seal that blocks humidity infiltration. 

For basements in humid climates or with moisture concerns, these options outperform fiberglass or wool alternatives.

Insulating basement walls provides the greatest benefit by reducing heat transfer through your foundation. This approach helps maintain consistent temperatures throughout your home and keeps floors above the basement warmer during cold weather. 

Ceiling insulation might be appropriate if you specifically want to isolate the basement from living spaces above. In most cases, addressing the rim joists and exterior walls delivers the best performance for energy efficiency and moisture management.

Many building codes require vapor barriers when insulating below-grade spaces like basements. These barriers help control moisture migration through foundation walls and floors. Certain insulation types, including rigid foam and spray foam, provide inherent vapor barrier properties. When using fiberglass or wool insulation, a separate vapor barrier becomes necessary. Always check local building codes for specific requirements in your area.

Signs that basement insulation needs replacement include persistent cold spots, unexplained increases in energy bills, visible moisture damage, musty odors, or mold growth. Physical deterioration, such as compression, sagging, or discoloration, also indicates potential problems. 

In older homes with outdated insulation materials, upgrading to modern options with higher R-values can significantly improve performance. When in doubt, professional inspection can help determine whether repair or replacement represents the best approach.
