Hi there from Dustin, owner of Insulation Nation! Here in So Cal, we join our Colorado office in providing personalized high touch experiences for our customers. I work with our customers directly every step of the way from evaluation, education and review of options, through the project and to inspection of the results. We've never seen less than a 5 star review. Small businesses live and die by reviews and we are ready to earn 5 stars on your project! Thank you! C-02 Insulation and Acoustic #: 1127373 EXP: 10/31/2026

"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

"Don't let the whole "family owned business since 1959" fool you. I had to have this company come back 3 times to do a job that should have been done correctly in the first place. They never covered all the open rodent accesses, so they had to call another 3rd party vendor. They left 25% of the vermiculite and had to come back for that. After fixing that problem, they never reinstalled the insulation that was moved in the back area of my attic. I contacted them back and the continuous response was "I will call you back" and it turns out that Cynthia (Ofc Mgr) stated that the owner doesn't know what else he can do for me. ***!!! They got paid for their horrendous service and now they are wiping their hands of any further obligations to make their work right. The people that gave good reviews may have not went into their attic to check out the work, like myself. IT IS HIGHLY RECOMMENDED THAT YOU FIND ANOTHER INSULATION COMPANY. DO NOT USE THIS COMPANY IF YOU WANT QUALITY WORK."

"The guys were really neat. They set up a tunnel from the attic to the back door. There really wasn't much to clean up after. They vacuumed out the old insullation and laid in new. It's hard to say if they did a good job in the attic, because I don’t know what its supposed to look like. They were in the attic almost about 7 hours. The only issue was that they said the senior discount on their Angie's list page must be old so they didn't honor it."

Soundproofing services FAQs

Using recycled egg cartons to soundproof a room is ineffective because these thin, porous materials fail to block sound waves. High-quality sound-dampening foam panels absorb sound energy completely and have a flat backing for secure attachment. This method guarantees enhanced noise reduction and an improved aesthetic, making it the reliable choice for soundproofing.

Soundproofing performed during new construction is more cost-effective than retrofitting an existing room. Incorporating soundproofing while building eliminates the need for extensive retrofits later, reducing labor and material expenses. New construction projects invest $15 per square foot, while retrofitting requires $30 per square foot. This proactive approach significantly enhances acoustic performance and value.

The best soundproofing approach is determined by the noise severity, room function, and the quality of materials used. For minor ambient noise, installing soundproof curtains may suffice. However, spaces exposed to heavy traffic or industrial sounds require insulation, specialized drywall, and superior window installations. Professional consultation ensures that every element meets the room’s acoustic requirements.

Sound Transmission Class (STC) quantifies a material's ability to block sound; higher STC ratings indicate superior soundproofing performance, ensuring less noise passes between spaces. This rating is essential when selecting windows, doors, or wall materials to meet specific acoustic performance standards.

While completely soundproofing a room is technically possible, it is not cost-effective due to extensive material and labor requirements. Targeting a noise reduction between 25% and 50% delivers significant acoustic improvement without exorbitant costs. An investment between $1,000 and $2,000 achieves outstanding results. Therefore, attaining complete silence is impractical for most residential projects.
