Denver's Home Energy Sealing Contractor
Most homes lose a significant amount of conditioned air through gaps and cracks that are easy to overlook: around recessed lights, at the top plates where walls meet the attic, along rim joists in the crawl space, and through penetrations where pipes and wires pass through framing. Cold air coming into the house in winter and heat pushing in during summer both trace back to the same problem.
EcoGreen Comfort Group is based in Denver, NC and handles air sealing as part of a broader approach to home energy efficiency. We work alongside our HVAC, insulation, and crawl space teams so the sealing work and the mechanical improvements are coordinated rather than patched together by separate contractors. Need something beyond air sealing? We offer HVAC, plumbing, electrical, and more.
“A new HVAC system will not fix a leaky house. If the conditioned air is escaping through the attic or crawl space before it reaches the living area, the equipment works harder and the homeowner pays more. Sealing the envelope first makes every other improvement work better.”
CEO of EcoGreen Comfort Group
Our Air Sealing Services
Air sealing is diagnostic work before it is remediation work. We locate the leakage points first, prioritize by volume and impact, and seal them in a sequence that makes the most difference for the least disruption to the home.
- Blower Door Testing
- Attic Air Sealing
- Crawlspace Air Sealing
- Rim Joist Air Sealing
- Exterior Wall and Penetration Sealing
Most homes lose more conditioned air than homeowners realize. A blower door test tells us exactly where and how much before any work begins.

Air leakage is often invisible, but its effects are not. These are the most common signs we see in Denver and Lincoln County homes before a sealing assessment.
- Rooms that are always too hot or too cold
- Energy bills that keep climbing
- Cold floors in winter
- Drafts near outlets and switches
- Dusty supply vents
- High humidity inside in summer
If you are noticing these issues in your home, EcoGreen Comfort Group can help identify where air is escaping and recommend the right solutions to improve comfort and efficiency.
