Over 20 years of experience in the home comfort and efficiency field. We find solutions to the issues that your HVAC company can't. Dusty homes, hot and cold spots, high utility bills, drafty fireplaces, rooms above garages, cold floors, dirty carpet edges, and much more can be fixed by us. We provide "comfort and energy solutions".

"A total disaster. An inexperienced, untrained crew created more issues than I had before they began their work. My goal was to increase comfort levels in my senior-living, one-level home built on a slab that is super cold in the winter. I hate as a senior being taken advantage of. I was very naive. I have spent thousands and now am having to throw more good money after bad to try and make my home comfortable to live in. It is so bad; I am ready to sell! And I can’t afford to after all I have spent, without taking a loss on the sale. They dense packed my walls and now I am colder; in the process, they removed the flashing above my windows which now leak. I had to hire a window installer to replace the flashing that their incompetent crew removed. They failed to put back the siding properly, so it was hanging off my house. Once again, I had to hire a handy man to refasten the siding the crew removed while dense packing. And the dense packing was useless as it didn't enter the cavities that already had batt insulation. While spray foaming triangle boxes, boots, and plenum, they sealed off all my dampers resulting in zero air flow. They reluctantly came back and had to dig out the dampers that they had foamed over. In fact, they over-foamed at junction boxes, boots, and plenum so that HVAC techs couldn't even tune my system. There is 2 feet of foam, yet hot air is rushing out of the flexible ducts that weren’t sealed properly. Yet there remain gaps on my boxes, boots, and plenum. Just today, a HVAC tech walked me around the attic, and I could feel the hot air rushing into my attic at the junctions, boxes, boots, and plenums that are all wide open; that I paid to have sealed. I almost threw up; I am heating my attic! And the tech said it looks like a dog was in my attic as the Comfenergy crews failed to put back my blown-in fiberglass insulation they removed when trying to foam, so there is no insulation at the boxes and boots. They were simply careless and failed to rake it back and even out my insulation resulting in further cold spots I didn't have. In short, I now will have to hire another company to blow in more insulation and make sure it is even, so I don't have cold/hot spots. Additionally, they left the lights on in the attic, didn't replace the attic access foam barrier, and failed to seal the major penetrations including light cans/recessed lights and supply vents I paid for. Next came the bathroom exhaust fans; they were installed improperly and didn't vent because the outside flaps remained closed, while inside a cold draft came in my bathroom because the foam sealing, I paid for wasn't done properly. So now both my bathrooms are drafty. They were cold; now they are cold AND drafty. The HVAC tech today remarked he felt badly that I have two or more space heaters in every room, including the bathrooms! I strongly recommend carefully watching the crew if you ever choose to allow them to do any work for you. I trusted them. And I regret that. I was naive. I was cold. Rather I am still cold! I trusted their salesperson. The crew that did mine were either let go or quit. In fact, one of them still calls seeking to do side work. I politely declined. I suggest you do the same and seek a competent company that you can trust, does the work you paid for properly, and doesn't damage your home."

We offer many different types of custom work. An exciting mix of strategies contributes to the high success rates of implementing energy efficient insulation. Whether it’s using more organic materials, denser materials, or premium insulation materials, energy efficient insulation is designed to cut back on energy and fuel consumption upon installation and through many years of use. But the biggest attraction of energy efficient insulation among our clients is the lower energy cost that comes from outfitting your home with these state of the art and cutting edge insulations.

Then our skilled group of installers will make sure that your new insulation is placed in your home correctly, to ensure that you maximize energy efficiency.

"When my Dominion Home Energy Report showed that I “used 101% more electricity than average homes,” I knew it was time to do something! I read reviews and then reached out to several companies for an estimate to replace my attic insulation. Capital Insulation provided an itemized quote that was the best value. I was happy every step of the process from working with Karl on the estimate to scheduling the installation with Lisa and communication with the crew while they did the work. The installation was completed quickly, they cleaned up when done, and payment via bank transfer was simple through QuickBooks. I will gladly recommend Capital Insulation to friends and family."

FAQs for insulation install or upgrade projects in Springfield, VA

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.
