Hours: Monday to Friday 8:00 AM – 6:00 PM
Keeping homes warm during Denver’s harsh winters is a big concern, and Denver Spray Foam Insulation seems well-equipped to handle it.
Their insulation strategies are tailored for the Front Range, designed to manage the wide temperature swings we get here. Their closed-cell foam applications provide structural reinforcement, especially helpful for older homes in high-wind areas.
They also offer crawl space solutions that combine foam with vapor barriers to reduce moisture issues.
Getting a free estimate is also simple and pressure-free. They’ll even help you navigate local power company rebates to get the most out of your investment.
The main drawback is scheduling. The business is closed on weekends, which makes coordinating a project a bit tricky if you work standard weekday hours.
They also only provide full-service professional installation, so you can’t buy materials to do a DIY project on your own.
Customer Reviews
Great service! I had my garage insulated with their spray foam and it’s feels so cool now before it was scorching. I can sit in my garage and enjoy it now. I’m glad that my friend recommended them. They also were very professional and didn’t take as long as I thought they would to finish. I would definitely recommend to anyone who needs to have installation done. 10/10

Address: 3888 Adams Street

Hours: Monday to Friday 9:00 AM – 5:00 PM | Saturday 9:00 AM – 1:00 PM
Upgrading building efficiency often involves navigating complex paperwork, but EcoTru Spray Foam Insulation makes the process incredibly smooth.
As an approved Xcel Energy Trade Ally, they actively manage the rebate documents to help clients secure financial incentives.
We recently spoke with a property manager who hired them, and she was particularly impressed by the team’s free post-installation thermal imaging verification to prove complete coverage.
EcoTru’s technicians also strictly use American-manufactured, premium materials that are safe for indoor air quality. They also hold rigorous Spray Polyurethane Foam Alliance (SPFA) certifications, bringing technical precision to every job site.
They even provide a contractual guarantee to finish projects under 2,500 square feet within a week and a half.
However, this built-in 7 to 10-day lead time means they cannot accommodate immediate emergency repairs following sudden weather damage.
Additionally, their digital quote forms require users to opt in to automated text communications, which can bother privacy-conscious individuals.
Customer Reviews

3. Mile High Denver Spray Foam Inc.
Website: https://www.milehighdenversprayfoam.com/
Address: 1780 S Bellaire St
Contact: 720-740-4664
Hours: Monday to Saturday 7:00 AM – 7:00 PM | Sunday 9:00 AM – 5:00 PM
Older properties often need more than a simple spray to fix insulation problems. Mile High Denver Spray Foam Inc. takes a customized approach, starting with a detailed property inspection rather than using a one-size-fits-all method.
They have the specialized equipment needed for complex insulation removals and targeted repairs to restore failing systems.
Beyond standard spray foam, they also offer blown-in and fiberglass options for tighter budgets.
Their expertise spans residential, commercial, and industrial properties. They can even provide acoustic dampening to reduce neighborhood noise.
That said, they don’t offer 24/7 emergency support. Their phone lines are only monitored during regular office hours too, which can make sudden moisture issues hard to address at night.
They also require an in-person inspection before providing a final quote, so quick online estimates aren’t an option.
Customer Reviews
Very professional team, I would definitely work with them again. We decided to go with spray foam when we renovated and I’m very happy with the decision. Already seeing a reduction in my energy costs.
- MB | Google Reviews
My decision to choose spray foam insulation was a result of much deliberation and research, and their extensive experience with correctly sealing my home was a valuable asset. Realtors will sell my home more quickly if they know I will have lower energy bills by 50% to 60% compared to homes of the same size. My new homeowner will save at least $2,000 per year.

4. Denver Precision Spray Foam Insulation
Website: https://www.denvercosprayfoam.com/
Service Area: Denver, CO and surrounding areas
Contact: (720) 702-8098
Hours: Monday 7:00 AM – 7:07 PM | Tuesday to Friday 7:00 AM – 7:00 PM | Saturday 8:00 AM – 6:00 PM | Sunday 9:00 AM – 4:00 PM
Scheduling major maintenance for commercial properties can be tricky without disrupting daily operations. Denver Precision Spray Foam Insulation addresses this by offering flexible after-hours appointments that work around a business’s schedule.
When I managed a downtown renovation last year, having contractors who could handle overnight shifts made a huge difference.
They organize their teams into specialized crews focused on different types of buildings. Their equipment is also designed to handle tight attic spaces efficiently.
Preliminary pricing estimates are easy to get over the phone, which saves time.
But while phone estimates are quick, the process relies heavily on verbal communication rather than automated digital tools. You still need to schedule a mandatory on-site visit with a technician to finalize the contract before work can start.
Customer Reviews
What a genuinely professional experience from start to finish. Angel was responsive, flexible on timing and worked quickly and efficiently. Given the really cold weather we’ve had for spurts throughout this winter, getting the spray foam insulation was a huge help. Energy bills have been consistently lower, house is warm…it was just really good all around. I’d highly recommend.

We had our old fiberglass insulation removed from our attic. It was gross and I’m happy it’s gone. They added spray foam and were done the same day. Very easy to work with, on time and their price was very reasonable.

5. OnPoint Denver Spray Foam Insulation
Website: https://sprayfoamdenverco.com/
Address: 2121 N Marion St
Contact: (720) 702-9660
Hours: Monday to Saturday 7:00 AM – 7:00 PM | Sunday 8:00 AM – 5:00 PM
Reducing your carbon footprint while lowering utility bills is possible with the right insulation contractor. OnPoint Denver Spray Foam Insulation focuses on eco-friendly materials designed to improve long-term thermal efficiency.
Before starting any work, the team conducts a detailed thermal assessment to pinpoint areas of heat loss.
Their applications are built to meet or exceed local building codes for Front Range weather. The dense foam also acts as an acoustic barrier, helping seal gaps and complementing pest control by keeping rodents out.
Quotes are straightforward, with clear upfront pricing. Just note that they require a mandatory pre-inspection to check for any structural issues before final numbers are given.
One downside is the equipment. Installing the foam requires large, heavy machinery, which can temporarily disrupt driveways during the process.
Customer Reviews
We had the old insulation removed from our attic here in Lakewood. They added spray foam insulation and the entire insulation removal and installation took only a couple days. We’re very happy with the results and looking forward to increased energy efficacy this winter and for years to come. Great team to work with.
