B. McLaughlin Quality Construction LLC has been providing quality home improvement and home building for many years now and prides itself on providing customer satisfaction where other companies fall short.

Unlike other contractors, their phone number has not changed since beginning out of college training since 1994, and their belief is to start your job and finish it before starting the next projects. With a free estimate sit down with Brian from the beginning, you will soon recognize the professionalism and sincerity to get your defined project to a complete stage with minimal worries and concerns. While words on paper are just that, let Brian show you what others leave behind, and he makes you (and your project) the priority.

"Our experience with New Leaf Construction in December led us back to hiring them again for a few additional projects we wanted completed outside this spring. The remodel of our firm over the winter was very successful and it was a pleasure to work with their crew. Their professionalism showed throughout the entirety of the project, from the quality of their work, sensitivity to our timeline, accommodating the needs of our business with as little interruption as possible, cleanliness of their work area, attention to detail, and staying on budget. I highly recommend New Leaf Construction."

We have been in the building trade for 25 years and added specialty weatherization 6 years ago. We are certified contractors for Maine State Housing Authority and Efficiency Maine. We are EPA Certified Lead Safe Renovators and fully insured. BPI Certified.

"Horrible Job! This outfit changed their appointment times at least five times before actually starting the job. They blew cellulose insulation into our east bedroom attic, but had complete disregard for the mess they created. They ran the discharge hose up through an open ceiling hatch with no attempt at sealing the opening. As a result, cellulose debris & dust was EVERYWHERE! It took my wife and me several hours of vacuuming, washing items, shaking out blankets and rugs, and serious dusting to get the spaces back somewhat civilized."

Insulation questions, answered by experts

Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they’re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.

Most homeowners installing blown-in insulation as a one-off DIY project should simply rent a blower. They tend to be very heavy, and contractor-grade machines can cost $13,000 to $16,000.

Yes, spray foam insulation can be applied to your ductwork and effectively insulate your ducts. Blanket insulation is the easiest insulation product to DIY since it is easy to wrap around ducts. However, spray foam insulation can also benefit your HVAC system if applied to air ducts.

Excluding carpet, strand-woven bamboo provides excellent underfoot heat. Laminate flooring is also good for insulation and preventing cold feet in the winter. Bamboo tends to work better in climates that have more consistent temperatures, while laminate does a better job at insulating floors in homes that experience more extreme temperature changes, such as the deciduous climates of the northeastern U.S.

When installing metal siding, a high-quality house wrap is considered the best protection against condensation and moisture infiltration. House wraps can increase a home's efficiency significantly. However, a house wrap is not a replacement for a vapor barrier because it can be permeable when moist air passes through siding. This is why it's essential to follow manufacturer instructions for insulating siding when installing new siding.
