Insulation Services
Insulation Services

Energy Savers SI offers Attic, Wall, and Crawl Space Insulation to make your home more comfortable and energy efficient. In most applications, our preferred choice is Blown-in Cellulose. Cellulose reduces air infiltration and energy loss better than fiberglass due to its density. Cellulose is also the best environmental option because it’s made mostly of recycled materials including newspaper. It consists of nearly 85% recycled paper fiber and the other 15% is a fire retardant.

Air Sealing
Air Sealing

Before insulating, our local professionals Air Seal all wire and plumbing penetrations, top plates, and any breach in the building envelope. This lowers your homes air leakage rate and allows the new insulation to perform at peak R-value. Although some of these penetrations and air leaks are not very large, adding up the total linear footage can easily be the equivalent of having a window open year round. Remember: Insulation slows down heating and cooling loss while Air Sealing stops it.

Crawlspace Encapsulation
Crawlspace Encapsulation

You will benefit when we properly seal your crawlspace and install a new sump pump system. Avoiding mold and pest issues and structural damage are among the most important. Lower energy bills are also realized. Our customers have gained up to 25% savings on their energy bills. Increased comfort levels are also realized and floors are no longer cold above your crawlspace. Moisture-related issues and damp smells are no longer a problem and indoor air quality greatly improves.

Vinyl and Steel Siding Services
Vinyl and Steel Siding Services

We perform new vinyl and steel siding installations. You can achieve many looks due to the wide selection of styles, shapes, and available colors. Our premium insulated siding is a great choice with energy efficiency in mind. Wooden studs in exterior walls can reduce your home’s energy efficiency due to “thermal bridging." This occurs when materials with poor insulating properties come together and allow hot or cold to pass through. Insulated siding acts as a blanket and reduces this effect.

Energy Star Windows
Energy Star Windows

We install Energy Star rated windows with Low Emax and Argon Gas filled panes for maximum energy saving performance. These certified windows can lower your energy bills and add comfort to your home, especially when replacing older, leaky single pane styles. Once we properly install new windows, our pros will air seal/insulate the surrounding frame. You will use much less energy and keep money in your pocket while also benefiting the environment by reducing greenhouse gas emissions.

Energy Star Doors
Energy Star Doors

Energy Star certified doors help insulate your home and create a tighter seal around the openings of your home. Air leaks are very common around doors and contribute to increased energy waste and larger utility bills. When you purchase Energy Star doors you are guaranteed a quality high performance energy saving product.

Whole House and Spot Ventilation Services
Whole House and Spot Ventilation Services

Exhaust fans such as the Panasonic Whisper Green Select are ideal for homes that require mechanical ventilation due to a low air leakage rate. This exhaust fan controls unwanted moisture buildup, improves Indoor Air Quality, and offers several configurations and multiple flow rates controlled automatically by smart modules. For homes with air quality issues, it can contribute to a healthier indoor environment for your family, and also provides whole-house continuous ventilation when needed.

LED Lighting Upgrades
LED Lighting Upgrades

We offer whole house LED lighting upgrades because they are by far the most efficient way of illuminating and lighting available today. LED bulbs possess an efficiency rating of up to 90% when compared to traditional light bulbs. This means that about 90% of the electrical energy is converted to light, while approximately 10% is lost and converted into heat. On the other hand, traditional incandescent light bulbs operate at 20% energy efficiency and 80% of the electricity is lost as heat.
