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!”

In 2025 @ducasconstruction,@developerscollaborativ In 2025 @ducasconstruction,@developerscollaborative, & Invivid Architecture transformed a formerly mixed use building located at 509 Forest Ave in Portland, ME into 38 loft-style apartments. 

This historic brick building was built in 1928 and had to adhere to strict historical society requirements while meeting modern performance standards related to airtightness, insulation levels, and HVAC improvements.  Like many other historical renovations, the HVAC improvements and insulation levels are clear and measurable during the design. 

Airtightness is a whole different beast to say the least. Each residential floor was required to meet or exceed 3 Air Changes per Hour at 50 pascals, but the exterior walls were to remain in their existing condition less some repointing of the brick. In addition to that, each floor started with a baseline air leakage of 9-14 Air Changes per Hour. Situations like this have and continue to put construction teams in a serious pickle. 

We were able to eliminate this pickle all together via Compartmentalized AeroBarrier Applications.  By sealing all 38 units to 1.5 Air Changes per Hour, each floor tested out between 2 - 2.2 ACH50 passing the City of Portland’s Blower Door Testing requirements with flying colors. Rumery Lofts is yet another case study which demonstrates the Value Proposition for AeroBarrier in Historical Renovation Projects.
