What is weatherization? Weatherization is all an all-encompassing approach to improving the performance of a building by treating the house as a system. This takes into consideration all of the elements that can affect a structure. A home of any age can benefit from weatherization, even new construction.


Energy Assessment / Energy Audit

This is the first step in the "house as a system" approach.  We utilize a blower door and thermal camera scan to provide you with information about your current energy inefficiencies and inform you of the necessary steps to reach your specific retrofit goals. The blower door establishes a baseline reading on air leakage and heat loss occurring within the property. With the blower door running, we perform a thermal camera scan to visualize insulation voids and devalued insulation (fiberglass) due to air movement.  We also analyze your mechanical systems (heating, hot water and ventilation) to determine their operating efficiency and confirm safe operation.

All information is drafted into an easy to read assessment report, complete with photos listing all weatherization and mechanical system recommendations for the property. We also include rough estimates per location to help our clients formulate solutions based on available budget and property goals. Once weatherization is complete, we conduct a free post audit to confirm combustion appliance safety and quantify the air flow reduction achieved.


Air Sealing

Any gap, crack, chase or hole in your home is a place where outdoor air can come in and/or heated air can exit. Prior to insulating any location, air sealing always needs to occur, otherwise insulation will most likely be devalued and be effective. 

Examples of drafty locations include: window & door trims/ jambs/ door sweeps - chimneys connecting the basement/ house/ attic - sill plates - light fixtures - exhaust chases (i.e. bath & kitchen exhaust fans) - unsealed interior wall top plates from the attic - oil pipe/gas line chase holes going outdoors - bath fan/ dryer vent caps


Insulation: Retro-Fit & New Construction

Basement & Crawlspace: Rim Joist - Foundation Wall insulation - Basement/Crawlspace Ceiling Insulation - Basement Chase Hole Air Sealing - Bulk Head Doors/Hatches (Products Used: closed cell spray foam, open cell spray foam, rigid board insulation, rock wool batting, low expanding canned foam, silicon, caulking...)

Attic, Cathedral and Vaulted Ceiling: Old Insulation Removal & Disposal - Ventilation Management (gable, eave, ridge) - Insulate Around Skylights - Build/Install Raised Storage Platforms - Insulate Flats, Slopes & Vaulted Ceiling Sections (Products Used: cellulose (loose & dense pack), rock wool batting, rigid board, closed cell spray foam, open cell spray foam, Tenmat recessed light covers, Accuvent proper venting, Intello Plus smart vapor control barrier, Insulweb...)

Wall Insulation: Drill & Fill (interior/exterior) dense pack cellulose only, Swath Access (interior/exterior to remove existing insulation - i.e. fiberglass) dense pack cellulose only, Open Stud Wall Cavity (New Construction/Renovation): dense pack cellulose, rock wool batting, closed cell spray foam, Insulweb netting, Intello Plus smart barrier


Moisture Management: Integral to maintaining adequate indoor air quality and a safe living environment. If you air seal and insulate a home that has moisture issues, you run the risk of rotting the home from the inside out. Signs of high levels of moisture in a home are: standing water in the basement/crawlspace, exposed dirt floors, moldy foundation walls, extensive condensation on windows (in the wintertime), rusted nails in the basement/attic, mold in the attic...

Some Solutions: install vapor barrier to exposed dirt floors, install gutters, improve exterior grade drainage, install a french drain within the basement, install mechanical moisture management systems (i.e. dehumidifier).
