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 (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 ( 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!”

- Anne G (Homeowner, Maine)

“After very detailed site visits, proposals and conversation with Alex, I hired him to facilitate a “whole energy upgrade” on my 1970’s (not an easy task) home…Alex and his team were incredibly organized, respectful and communicative…I knew exactly what was happening in my home and on my property with advanced notice and opportunity to weigh in. His two week timeline estimate was right on track, with cleaners coming in just two days before Christmas to leave my home sparking clean. He was methodical about alerting me to any changes and ensuring my home and family felt safe with multiple contractors in and out daily… They started each day by protecting my floors and ended each day sweeping, mopping, replacing furniture and even leaf blowing sawdust and scraps off my driveway and yard left from other subcontractors.”

Short answer: Absolutely.

Even in an intricate basement setup with geothermal equipment, AeroBarrier is completely safe. With precision masking and proper setup, we shield your sensitive gear while fortifying the building envelope.

Relentless prep isn’t just a step in our process; it’s our standard.

One of our favorite traditions of the year is bringing together our team, families, friends, and the people who make LBS what it is. Great food, great company, and a chance to celebrate another year with the people behind it all.

Darrel is our type of guy! With a background in re Darrel is our type of guy! With a background in residential frame-to-finish carpentry and a degree in Construction and Design from SMCC, Darrel is the definition of a dual threat. 

On any given day at LBS, you’ll find him meticulously sealing up building envelopes as an air sealing tech or wielding a hammer as a carpenter in our General Contracting Division. When he’s not obsessing over airtight structures and fine woodworking, Darrel loves getting outdoors, trivia, and listening to heavy metal—which makes sense, considering his workday already revolves around pressure testing, robust air seals, and heavy-duty precision.
