Lord Building Solutions is an air-sealing shop. A wmtw.com news story named Alex Lord as its owner and said the company specializes in air sealing, and a greenmainehomes.com article quoted him as the owner of Lord Building Solutions in North Yarmouth on AeroBarrier sealing. The company's website lists air sealing, Aeroseal, air leakage testing, blower door testing and duct blasting, and says it has been in business 18 years. A 2025 Google customer said they hired Alex to run a "whole energy upgrade" on a 1970s home: adding insulation, replacing outdated insulation, ventilating bathrooms, bringing plumbing and electrical up to code and installing heat pumps to replace electric heat. That 2025 customer said the heat pump tracks through the walls were sheetrocked, mudded and repainted, and that the two-week timeline estimate was right on track. The same 2025 reviewer wrote that Alex or his counterpart Rufus was on site at all times to oversee subcontractors, and that each day started with protecting the floors and ended with sweeping and mopping. A 2025 customer said they worked with Alex on an Aeroseal during a whole home renovation and that he kept to the agreed schedule. A 2024 customer said they had air sealing and new insulation done throughout the home, and that Alex Lord and his crew explained everything and finished the work quickly.
““AeroBarrier can fill holes the size of a human hair,” says Alex Lord, owner of Lord Building Solutions in North Yarmouth, one of a few Maine contractors licensed to work with these products.”
“So instead of stripping the exterior or interior, we used AeroBarrier, installed by my son Alex of Lord Building Solutions.”
“said Alex Lord, the owner of Lord Building Solutions, which specializes in air sealing.”
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. This consisted of adding insulation, replacing outdated insulation, ventilating bathrooms appropriately, bringing various plumbing and electrical up to code and installing heat pumps to replace my existing outdated electrical heat. The tracks to the heat pumps through my walls were sheet rocked, mudded and re-painted as if the large (necessary) holes in the walls were never there. 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. He ensured either himself or his counterpart Rufus were on site at all times to oversee subcontractors and ensure the site was opened and closed appropriately. 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. The card and holiday cookies from Alex’s wife and kids was the cherry on top! Highly recommend Lord Building Solutions.
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!
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 word they did! I would highly recommend Lord Building Solutions to anyone.
