Dalton and the guys did a great job with regards to insulating the attic. Efficient, professional, and they completed the work in a timely manner. I was impressed and appreciated their work ethic. They took time to explain the work including showing me pictures of the completed job. Hard to find a company that takes the extra steps and time to make sure that I was satisfied the job was done right. Thank you to Insulation Pros and the guys.

I highly recommend Insulation Pros of KC for your insulation needs. Kyle the Sales Manager: made it easy to understand what I needed. Josie the Office Manager: took the time to answer my questions when I called, and was the one responsible for my decision to go with Insulation Pros. The installation crew: Devon, Tyler and Leo were a great team to work with, very personable and just all around nice guys who did a great job with the installation. Tanner - the Production Manager, who came by to see that everything was going like it should. From the first meeting with Kyle, to the time the crew drove away, it was easy and pleasant to work with this company and they did a great job. Attached are pictures to show the 22" of insulation in my attic! :)

Excellent experience from the very beginning throughout the entire process. Nic arrived within a couple days of my initial call to walk through, take measurements and explain the best approach for insulating the basement, attic and above and below a mudroom with crawl space. Josie was very helpful in discussing my concerns and scheduling the team. Jostin and the team did an excellent job on the scheduled day. And when there were a couple follow up concerns Tanner made a two trips out to do some detailed and quality touch ups that really topped off the overall experience. They were all highly professional and polite and I’m very pleased with the results!

They went above and beyond our expectations! Would definitely use this company again, both affordable and quality of work was good. We hired them for a "new construction insulation" up to code. They were very fast and did an excellent job

I was paired up with Williams through an energy audit provider for Evergy. On the morning of my insulation, Williams called me to confirm timing. I attempted to confirm the services being provided when they informed me the intermediary changed the services so they could do half (kneewall overlay) and Williams would do the blown in part. This didn't make sense to me as once you blow in the new insulation you don't want to disturb it. In the end Williams went above and beyond making sure I was taken care of and even recommending additional areas that could use more insulation that were not on the audit report. I would highly recommend Williams for your insulation needs.

Horrible service. Hired them to come out and install insulation in our building. It took over a month and 10 trips to complete the work. When the workers showed up they didn't even know what kind of work was to be done. Had 3 or 4 of the guys show up to seal the floor that didn't need sealed. After they finally completed the isolation most of it was falling down and they had to come back again and tape it all up. This company is not very professional at all and I would not recommend them to anybody.

Frequently Asked Questions — Spray Foam Insulation in Kansas City

These are the questions Kansas City 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 2 verified Kansas City contractors above for exact quotes.

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