Jeff and Hollie Martin★★★★★2 months ago

The owner (Scott Brooks) was a great communicator throughout the initial phase. His installation team did a great job. They even threw in an extra bag of cellulose and cleaned up well. Will recommend.

I have been struggling with keeping house cool during the summers and warm during the winters. Made a request to iFoam for an evaluation and was promptly contacted and had the evaluation done within a day! Bryan explained everything clearly with his recommendation. Signed everything that same day and just had them at house to complete the job. Can't wait to see the impact that it has to keep house warmer and savings over the next few months. Only thing I wished could have been done was having this done sooner!

I was greatly satisfied with the services rendered by KOALA. Their employees demonstrated good teamwork and time management. They arrived on time and came well prepared. Each employee was very professional (very polite). All of the work was completed to my expectations - including their good housekeeping skills. All debris was removed inside and out. Surprisingly, the price was very affordable. Moreover, the smiles and gentlemen-like behavior was greatly appreciated.

Very knowledgeable all the way from sales to installation. We had a solar fan installed and immediately made a positive impact on how much we ran the air conditioner. I wish I had known about this years ago. Thank you to everyone at Koala.

Tim McGue★★★★★a month ago

Got us filled up to R49 and some insulation rolls. Ryan and team kept me well updated during the process of blowing in the insulation. They took lots of pictures of the attic. I was really happy and would recommend. We had a delay in the initial quote which they said was a new system, but once we got on track everything was great.

Mindy, came and explained the process… The guys who installed were fast and left no cellulose mess behind… the price was affordable! Can’t be happier with Foam Engineers and their staff.. referred them to my neighbor who’s getting her attic done too!

Kellee Wright★★★★★3 weeks ago

Foam Engineers has exceeded my expectations. I’m a project manager for a home renovation company and have worked with Foam Engineers on my last two projects. Their pricing is very competitive, and their service is outstanding. Dave and his crew installed both spray foam and batt insulation on my most recent project. They were prompt, professional, and maintained excellent communication throughout the process. They went above and beyond in both scope and execution. I’ll continue to use Foam Engineers for future projects and have already recommended them to my colleagues.

Leslie Morton★★★★★3 months ago

Very impressed from start to finish with Foam Engineers! Mindy came out for the estimate and was extremely thorough in explaining the process of installing cellulose insulation and the resulting benefits. The estimate was very detailed, including photos.The installation took place yesterday and we had a fabulous crew! Alex was the lead and impressed me with his knowledge and professionalism. Colin, Dylan, and Tony were all very competent and skilled workers as well. All were committed to the successful completion of the project in a timely manner. I had to run an errand and felt comfortable leaving the guys on their own. Mindy dropped by during the installation. Her attentiveness and follow-up were very much appreciated. I wouldn't look further than Foam Engineers for your insulation needs. Bravo to Mindy and the crew of four - thank you for a job well done!

Corey with US Spray Foam Rentals was great to work with. I did 3” of closed cell foam on the exterior walls of my house build. Saved some money by using their services. I will plan to use them again in the future and would definitely recommend them to anyone considering spray foam.

Cliff Watson★★★★★6 years ago

I just had the pleasure of working with Corey from US spray foam rentals. He was extremely professional, on time, knowledgeable, and their equipment was superb. I sprayed a 5000 s.f shop for 1/2 the price of using a contractor and the closed cell foam not only insulates but adds structure and rigidity to your building. If you don’t mind getting your hands dirty and like saving money then I wholeheartedly, absolutely recommend U.S. spray foam rentals.

Garrett C★★★★★7 years ago

U.S. Spray Foam Rentals is an excellent company to work with! I sprayed my building and saved a small fortune doing it. They did everything the said they would from start to finish. I would recommend this company to anyone looking to save on their foam project!

Frequently Asked Questions — Spray Foam Insulation in High Ridge

These are the questions High Ridge homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 35% typical energy savings. Compare the 4 verified High Ridge contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in High Ridge?▼
Homeowners in mixed climates like High Ridge, MO typically see 20–30% reductions in total energy costs after spray foam installation. The savings come from both reduced heating in winter and reduced cooling in summer. The exact savings depend on your home's current insulation, size, and local energy rates, but most homeowners recoup the investment within 3–6 years.
Is spray foam better than fiberglass insulation for homes in High Ridge?▼
For most homes in High Ridge, MO, spray foam outperforms fiberglass significantly. Fiberglass batts insulate but do not air seal — meaning conditioned air still escapes through gaps. Spray foam both insulates and creates an airtight seal, addressing the root cause of energy loss. While spray foam costs more upfront, the performance difference in mixed climates makes it the better long-term investment for most homeowners.
Is spray foam insulation worth the cost?▼
For most homeowners, yes. Spray foam creates an air-tight seal that traditional insulation cannot match, reducing energy bills by 15–35% annually. It also adds structural rigidity, acts as a moisture and vapor barrier, reduces outside noise, and can increase home resale value. The higher upfront cost compared to fiberglass is typically recovered within 3–7 years. One important note: because spray foam creates a very tight building envelope, proper mechanical ventilation is important to maintain healthy indoor air quality and prevent interior moisture buildup. This is typically handled by an Energy Recovery Ventilator (ERV) — a system that brings fresh outside air in while pushing stale air out, recovering the energy from the outgoing air so you don't waste what you paid to heat or cool — or a Heat Recovery Ventilator (HRV), which works similarly but is optimized for cold climates. A qualified contractor will assess whether your home needs ventilation upgrades as part of the installation.
How much does spray foam insulation cost in High Ridge, MO?▼
In High Ridge, MO and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. Open-cell foam runs $0.44–$0.65 per board foot, while closed-cell foam costs $1.00–$2.00 per board foot. A typical 2,000 sq ft home attic in High Ridge costs $2,000–$6,000. Most High Ridge homeowners recoup this investment within 3–7 years through energy savings of 15–35% annually.
What is the difference between open-cell and closed-cell spray foam?▼
Open-cell spray foam is softer, less dense, and less expensive. It expands significantly and is ideal for interior walls, attics, and soundproofing. Closed-cell spray foam is denser, stronger, and provides a moisture barrier — making it better for exterior applications, crawl spaces, and areas prone to flooding or humidity. Closed-cell also has a higher R-value per inch (R-6 to R-7 vs R-3.5 to R-4 for open-cell). One key difference: open-cell foam allows some vapor movement, while closed-cell acts as a vapor barrier — an important consideration for your home's ventilation needs.
How long does spray foam insulation last?▼
Spray foam insulation is one of the most durable insulation options available, with a lifespan of 80+ years when properly installed. Unlike fiberglass batting which can sag and settle over time, spray foam maintains its shape and insulating properties indefinitely. It will typically outlast the building it is installed in.
How do I find a qualified spray foam insulation contractor in High Ridge, MO?▼
When searching for a spray foam contractor in High Ridge, MO, look for ones who are licensed, insured, and have verifiable reviews. Spray foam requires specialized equipment and training — improper installation can cause off-gassing, adhesion failure, or fire hazards. Ask for references, verify their insurance, and get at least 2–3 quotes. A qualified High Ridge contractor will also assess your home's ventilation needs — a tightly sealed spray foam installation requires adequate mechanical ventilation to prevent moisture and indoor air quality issues. FoamMatch pre-screens all listed contractors in High Ridge for licensing and insurance so you can compare verified professionals in your area.
How long does spray foam installation take?▼
Most residential spray foam jobs take 1–2 days depending on the size of the area. A standard attic takes 4–8 hours. After spraying, the foam cures within 24 hours, though most contractors recommend waiting 24–72 hours before occupying the space due to off-gassing during the curing process.
Does spray foam insulation need to be replaced?▼
No — spray foam insulation does not need to be replaced under normal circumstances. Unlike fiberglass insulation which degrades over time, spray foam maintains its R-value and air sealing properties for the life of the building. The only reasons to remove or replace spray foam are water damage, renovation work, or improper original installation.
