"Dustin and Josh were great to deal with up front and stated they would do what I requested. After finishing the crawl space cleanout, it was noticed that the skirt doors were open and the cats were again in the space. I then hired someone to close up the openings. I crawled into the space which had a new vapor barrier and noticed that much insulation repair was not done as paid $500 extra for. Under the vapor barrier was very rough and bumpy and very hard to crawl on. they did not clean the rocks and cat messes up and the insulation was not repaired as promised and paid for.s I would not use them."

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!"

"They send multiple e-mails and texts before they arrive to let you know any additional services will be more than the $100 vent cleaning and if you don't want anything done, there is a $60 service call fee. This sets them up for the bait and switch. The tech went to one of the vents and immediately started telling me about how my freon in the AC unit would need to be recharged and on and on and on his sales pitch. He then told me the $100 was only for maintenance cleaning, I needed something else. So he pulls out a paper with like 6 different "levels" of warranty etc. The lowest one, for an 800sf place - 6 vents, 1 return was $1500. I told him I would pay him the $60 to leave. I ended up removing the blockage from kids dropping toys down the vent myself and learned the vent he was "inspecting" when he told me it was clogged - was in fact a return vent!! Do not trust these people. Bait and switch scam."

FAQs for insulation service projects in Castle Rock, CO
When choosing a professional insulation installer, consider asking these questions to determine the best fit.
Will you address air leaks in my house?
Can you provide an R-value (heat resistance) fact sheet?
What kind of insulation will work best for my home?
How do you handle signs of a water leak?
Are you licensed and insured?
Can you provide customer references?
The best type of insulation for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.
If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.
In some cases, you may not have enough insulation to properly regulate your home’s temperature. Watch for a few signs your home needs more insulation, such as:
High heating and cooling bills
Uncomfortable room temperatures
Ice dams on the edge of your roof
Roof leaks
Cold floors and walls
Freezing pipes
Temperature fluctuations
Visibly low insulation
Noise problems
Pest problems
On average, insulating an attic costs about $2,500, ranging from $1,500 to $3,500, depending on the insulation type, amount, and your attic’s accessibility. Additional cost factors include sealing air leaks, removal or replacement of insulation, and inspections. Types of insulation include:
Blown-in: $1–$4 per square foot
Spray foam: $2–$5 per square foot
Batt: $2–$4 per square foot
Structural insulated panels: $4–$7 per square foot
Loose-fill: $2–$5 per square foot
Reflective: $0.50–$1.50 per square foot
