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!”

The AeroBarrier Prep Process, performed in conjunc The AeroBarrier Prep Process, performed in conjunction with Incremental Blower Door Testing, provides critical data that informs air-sealing targets, evaluates on-site execution of the air control layer, and measures operational leakage in designed openings.

These are just a few of the adjacent benefits of utilizing AeroBarrier in your new construction or renovation project.

Always a pleasure nerding out with the @building_perf_cooperative Team!

From Conception to Completion in 3 months. Most p From Conception to Completion in 3 months.

Most people know us for air sealing. And that makes sense because it’s all we really talk about on here. It’s what we advertise.

But if a project is the right fit, we won’t just seal it, we’ll build it too. 

Our General Contracting Division took this basement from a raw, unfinished space to a beautiful gym with a sauna. No formal design. Just a vision with some high-end execution.

"If I have seen further it is by standing on the s "If I have seen further it is by standing on the shoulders of Giants.”

Construction is hard. You have to earn your keep. 

Mentorship in our industry can be the most influential factor in determining if you stay for the long haul, or bail prematurely.

Joining a company with standard operating procedures and proper workplace ethics helps, but it’s all about the people. The people who take you under their wing, and show you that they give a crap about your well being, education, and interests, but also push you to be the best version of yourself. Day-in and day-out.

I had the privilege of working under @ijswoodworking  for two years with @hudsonvalleypreservation. At the time, I knew that I was granted an opportunity to learn from the best, and I did everything in my control to take advantage of Ian’s knowledge. Observe his site presence. The way he approached his craft. His focus on delivering results for the company, our clients, and his colleagues. 

It’s been over 7 years since we worked together, yet his influence is more powerful today than ever before. As LBS takes some big leaps in 2026, I will continue to look back on where I came from to see the pathway forward.

“I don’t know where we’re going, but I know exactly how to get there.”

Mentorship isn’t just impactful. It is life changing.
