Anyone that has tried to hire sub contractors lately knows this, but for some reason it is extremely difficult many times even to get a call back, not to mention getting them to show up at the promised time once you have secured them for the job. Jesse and his crew at Midwest Spray Foam Insulators began our relationship when he spray foamed my new 40 x 80 shop. They arrived on the date and time as promised, they used plastic and taped off to insure the least amount of mess and that the spray foam only went where we wanted it. They got in, got the job done, cleaned up and they were on there way. I need to add that the invoice I was given matched exactly the quote I was given initially. I am currently building a new home now that my shop is finished. I didn't even bother calling anyone else! I called Jesse as I knew he would do a great job and give me a very fair price. Again, he and his crew showed up as promised and did a super job spray foaming my new home. I even had a couple of my other sub contractors comment on what a nice job Jesse had done. When someone does a good job for me, I will definitely use them again. Midwest Spray Foam Insulators have always kept an open line of communication with me, I never had to guess whether or not they were going to shop up, the price is always right and they do outstanding work! A lot of contractors talk a good show but Jesse and his crew actually put one on. Although I am sure there are other good spray foam companies out there, don't waste your time calling anyone else! Make the call to Midwest Spray Foam Insulators, you will be glad you did!

From the beginning, MSFI was fast to respond. Jesse provided options for closed and open cell and offered the most affordable option for my shed. Jay and Mary showed up early and went right to work. Prep work included covering everything. I did have the ceiling painted and it looks great. Since then, I continue to be beyond happy with the foam insulation. I went with open cell based on where I live and it has performed. Early January 25, we have had two days so far that have been below 25 degrees. The shop last night was still 53 without any supplemental heat. Pipes in walls are not frozen and I can work in the shop without a jacket on. The echo in shop is minimal too. Shed is a 40x56x12 and I installed a 8' ceiling fan to move air. I can bring the temp up 5 degrees in about 90 minutes with a ventless 30,000 BTU propane wall heater. Haven't been through a summer yet but I am expecting a nice environment with the fan and foam. I can't say enough good about MSFI and the job they did! If I ever build again, I will hire them to come do the work. Pricing was more than fair compared to others and the option Jesse proposed is perfect for my shed. Thank you Jesse, Jay and Mary for a great job!

MR. Foam Insulation Services makes the whole process of adding insulation very easy! From the sales rep to the installers, the whole crew is great to work with. The sales rep is very knowledgeable; he answers any concerns/questions as well as explains the installation process. He gives several options to choose from and doesn’t pressure you into doing anything you don’t want. The installers are on time and careful working around the belongings. They also explain what they will be doing before staring. One of my concerns was the mess it may cause, but the working crew were sure to leave the home as clean as it was when they arrived. I would definitely recommend MR. Foam Insulation Services to anyone, and I will be using them for any future insulation work.

Frequently Asked Questions — Spray Foam Insulation in Mount Vernon

Below are common questions Mount Vernon, MO homeowners ask about spray foam insulation cost, types, and installation. For local pricing and to compare verified contractors in Mount Vernon, browse the listings above.

How much can spray foam insulation save on heating and cooling bills in Mount Vernon?
Homeowners in mixed climates like Mount Vernon, 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 Mount Vernon?
For most homes in Mount Vernon, 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 Mount Vernon, MO?
In Mount Vernon, 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 Mount Vernon costs $2,000–$6,000. Most Mount Vernon 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 Mount Vernon, MO?
When searching for a spray foam contractor in Mount Vernon, 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 Mount Vernon 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 Mount Vernon 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.
