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!”

How DURABLE is the AEROBARRIER Sealant?⁠ ⁠ Followi

How DURABLE is the AEROBARRIER Sealant?⁠
⁠
Following fifty cycles of flexing and accelerated aging, simulating a fifty-year period of service, the sealant showed no evidence of cracking, crazing, or spalling. ⁠
⁠
Three factors were considered when assessing the durability of the AeroBarrier sealant during the third party testing – flexing, aging, and compatibility of the material.⁠
⁠
- Flexing is an important characteristic, because most joints within the⁠ building enclosure expand and contract due to changes in temperature⁠ and/or moisture, which requires the sealant material to accommodate⁠ that movement.⁠
⁠
- Aging is very important for the building industry, because some materials⁠ can break down over time due to leaching of plasticizers or other low-⁠molecular-weight volatiles, causing them to embrittle.⁠
⁠
- Compatibility is important with all building products because the sealant⁠ shouldn’t chemically react with or leach into other building materials.⁠
⁠
The Results:⁠
⁠
The Sealing Performance was 0.13% leakage when compared to the open-joint condition (no sealant present) after simulating 50 years of heating, cooling, different moisture levels, and building movement.⁠
⁠
There was no discoloration and/or material breakdown at the sealant interface with 41 dissimilar common building productions, indicating favorable compatibility. ⁠
⁠
The Conclusion:⁠
⁠
Buildings featuring solid design and detailed execution—paired with AeroBarrier—provide long-term durability, energy efficiency, and occupant comfort for a lifetime.⁠
