"I called asking for service at 1:00PM and John fixed the problem by 6:00PM. Five hours from first contact to job complete is pretty impressive. John did a quality job. He quoted the cost and explained clearly what would be done. He also didn't upsell which was great. I would highly recommend this company for any garage door need."

"We got the name of this company basically from random from a list of companies from the Oregon Energy Trust. The work they did with the blower test and energy audit was helpful and done well. It allowed us to understand the energy loss issues in our old home. The issues with this company were with the estimates provided for further work (ex. insulation installation, air sealing, asbestos removal). The quote was difficult to understand as to what work would be included and the prices seemed a bit high. For instance, the quote listed installing attic insulation for about $2200, but then later on listed slashing a vapor barrier on the existing insulation for only $600. The costs of both of these line items were totaled together in the overall bid price; however only upon talking to the company did I find out that these were "one thing or another" options and that they would not be done conjointly. Also, the final cost of the entire work was miscalculated which showed the work to be $3,000 cheaper than it actually would be. Some of the high prices included $175 per gable vent in the attic; I assumed this price included a fan, but in fact was basically just a whole in the siding with a screen installed- keep in mind these would be installed in an area of the attic that has easy access. The insulation quote to blow it in was $400 more expensive than a subsequent quote I received. For blower tests this company was fine, but I took my other work elsewhere."

"They did a real good job. They were real professional. We can now open the garage door from the inside of the house and now it is so smooth that we have to check to see if we hit the button to open it or close it.  Before we used to know when it was opening or closing because it used to make a noise. It helps when you move to a city where you are new. "

Energy Efficiency Auditing questions, answered by experts

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

A whole-house humidifier can positively impact energy consumption by improving heating efficiency. During colder months, humidified air feels warmer, which allows you to lower your thermostat without sacrificing comfort. This adjustment can lead to significant energy savings as your heating system works more efficiently. However, it's important to use the humidifier judiciously, as excessive humidity could potentially strain your cooling system in warmer months.

Yes, including optimizing settings and suggesting upgrades if needed.

To find a reputable home energy auditor, start by researching local companies that offer the service and check their reviews, methods, and certifications. The most reputable professionals are often Home Energy Professional (HEP)-certified by the Building Performance Institute (BPI). You can also consult the Department of Energy’s certified list of energy auditors or use a state licensing tool to review local guidelines and ensure you are hiring a certified professional for your area.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.
