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."

Basement Waterproofing questions, answered by experts

Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

Some disadvantages of crawl spaces are mostly regarding the air itself—moisture build-up and poor ventilation, which can cause problems both in the house and underneath it, even damaging the foundation itself. Crawl spaces are difficult to access and often invite unwanted pests during the hot summer months and the cold winter ones. These hard-to-seal spaces are also susceptible to water damage during periods of heavy rain or melting snow.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.
