What customers are saying

I worked with Alex to do an Aeroseal on my whole home renovation. Alex and his team did a great Job, his communication leading up to the project was excellent, he kept to the agreed upon schedule and I’m very happy with the results!

- Mike D (DIY Homeowner, Vermont)

Lord Building Solutions did and A+ job on my home. I had Air Sealing and new Insulation done in my entire home. Alex Lord and his crew did a fantastic job explaining everything and giving me the best possible price. Their work was done extremely quickly and there was little that I needed to do! As a new home owner, I was worried about people/contractors working on my home and if I could rely on their ‘expertise’. When working with L.B.S. I didn’t have to worry about a thing. They were friendly with my animals, respectful of my space/property and my home is better off from all the work they did! I would highly recommend Lord Building Solutions to anyone.

- Alex K (New Homeowner, Maine)

“He was very professional, communicative, responsive, transparent and ethical. He’s been one of the best contractors we’ve ever worked with. He even left us a dinner gift card!”

As Air Leakage Requirements become more aggressive As Air Leakage Requirements become more aggressive, understanding and measuring Operational Leakage is no longer optional, it’s Absolutely Critical.

The LBS Masking System and Diagnostic Blower Door Testing Process enables us to pinpoint exactly how much air is moving through the Operable Components in a building. 

Think of these components like Windows and Doors, Access Panels, and even Sprinklers. Even the best Designed Openings leak air. 

We measure this Operational Leakage before each and every AeroBarrier Application. This measurement informs our Air Sealing Targets to ensure that building Meets or Exceeds the Final Blower Door Testing Standards put forth by Code Enforcement, Commisioning Plans, and Ownership Groups.
We spend a lot of time Geeking out about Building We spend a lot of time Geeking out about Building Performance and Air Sealing, but projects like this Showcase the Full Scope of our Capabilities.

Intentional Design and Execution from Pre Construction to Finished Product is the LBS Way.

Pairing Building Envelope improvements with HVAC system upgrades is how we take Building Performance to the Next Level.
