We can be reached at 720-517-0011. We have been in the Insulation Industry for almost 3 decades now. We have done most types of construction projects from multi-million dollar commercial projects, small to large remodels projects and large track home developments. About 7 years ago, we started working with a few select custom green energy builders. This afforded us the opportunity to work directly with homeowners to develop insulation and energy plans that fit their needs. We quickly realized how much we enjoyed working directly with homeowners vs. a big builder that may not have the buyer's long term interests at heart.

"I had 1700 sf of attic space insulated and air sealed in a two attic, tri-level house. Ryan was absolutely awesome. He was very knowledgeable and answered everyone of my questions...I had a lot. They showed up early to every appointment. Once the job was completed, they did an awesome job cleaning up and vacuuming with their HEPA vacuum. I would highly, highly recommend these guys. They also filled out the Xcel rebates for me and subtracted from my bill. AND, they did a blower door test to validate the air leakiness of my house. They were able to reduce my leakiness by 52%!!! The next day, I could feel the difference already!"

Insulation questions, answered by experts

Yes, you need a 1.5-inch to 2-inch air gap in a cathedral ceiling to allow proper air flow and prevent cathedral ceiling venting problems. This amount of airspace allows warm, moist air to properly leave your ceiling to avoid moisture build-up and other issues that put your home at risk. You can also add an air vent for extra air flow.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Spray foam insulation doesn’t do well around heat sources. Therefore, You can use spray foam insulation to seal around HVAC boots that penetrate through the drywalls or around where wrapped ducts connect to the boots, but we don’t recommend using spray foam insulation to encapsulate your air ducts. Spray foam insulation on air ducts is also less effective compared to duct wraps.

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.

As you look for the right soundproofing drywall for you, you’ll likely come across the Sound Transmission Class (STC) rating. This rating measures a building material’s ability to absorb sound. The higher the number, the better the material absorbs rather than reflects sound, reducing noise transmission. The STC rating for drywall doesn’t mean it’s for the panel itself—it refers to the STC rating for the entire wall system, including the soundproofing drywall.
