We had a great experience! Shane and his wife are very open and honest about the whole process and were easy to trust! The job seems to have been well done and everything cleaned up well.

LORD LEE★★★★★2 months ago

Great job. House is now insulated air tight. We had to leave for a ballgame while they were still working, came home to a closed house with everything put away and cleaned up. Hope to be saving around 200$ a month in air conditioning and heating. This is one upgrade where you can get your money back. Thanks again for the great job. Lee Constien.

We had a great experience with this company. They topped off our attic and foamed all the exterior walls of our home. The crew was friendly, skilled and cleaned up after themselves. Our home had difficult aluminum siding but they put it back very well. This will give us peace of mind knowing we've done all we can to be as energy efficient as possible. We recommend them!

We recently worked with Spray Tight Insulation, and overall, the experience was excellent from start to finish. Their team was professional, punctual, and very knowledgeable about the products and installation process. The crew took the time to explain the benefits of spray foam insulation and answered all our questions in detail. They worked efficiently, kept the job site tidy, and made sure the installation was done to a high standard. The difference in temperature control inside the building was noticeable almost immediately—our heating and cooling systems don’t have to work nearly as hard now, and the space feels much more comfortable. Pricing was fair for the quality of work and materials provided, and the energy savings we expect to see will make it well worth the investment. I would highly recommend Spray Tight Insulation to anyone looking to improve their home or commercial building’s efficiency, comfort, and overall insulation performance.

I recently had Spray Foam Genie Columbus insulate my metal building, and I couldn’t be happier with the results. From start to finish, the crew was professional, knowledgeable, and efficient. They showed up on time, explained every step of the process, and made sure the job site was clean when they were finished. They worked thru some issues with their equipment but it was handled professionally. The quality of their work really stands out — the foam coverage is as agreed and consistent, and the temperature inside the building is now much more comfortable. I’ve also noticed a big reduction in outside noise. If you’re considering spray foam insulation for a home, shop, or metal building, I highly recommend Spray Foam Genie Columbus. Excellent workmanship, great communication, and a solid improvement to my building overall!

Communication with the team was wonderful, John was kind, clear, knowledgeable, and provided multiple options over a couple rounds of inquiry. His pricing was easy to understand and better than other estimates I got. (In fact, RPRo was recommended by a friend that works for a competitor!) Trusted contractors that do great work and charge fairly like this team are GOLD.

I reached out to R-Pro because I did a home energy audit with Columbia Gas and R-Pro was on their list of recommended insulation companies in the area. I got quotes from several other companies, and R-Pro was the clear winner because John actually spent time investigating our situation and recommended a very reasonable (not just the easiest/most profitable) solution. The price was comparable, if not cheaper than other companies. I should also mention that everyone I interacted with was professional and respectful to both me and my wife - unfortunately, that hasn't been true of all contractors we've hired in the past. Lee and Cole showed up 10 minutes early for our scheduled appointment, and they were great! They did the job efficiently and didn't leave behind a mess. I loved that they knew exactly what to do even though it was not a straightforward job with several major tasks. I didn't have to re-explain everything to them! The work they did aligned with the detailed contract written by John. Lee and Cole were more than happy to allow me to inspect their work at various checkpoints of the project, so I'm confident that they did a good job. We now have fantastic insulation in our attic and garage ceiling of our split-level home. They also installed a solar-powered attic fan and soffit baffles that I'm super excited about. Our attic used to get extremely hot due to poor ventilation, but now that should be fixed! I will definitely be recommending R-Pro to friends in the Columbus area.

John Scully★★★★★a month ago

just built a 30x65' metal building, part has 16' walls. Contacted r-pro to so 3" of closed cell foam insulation. They responded quickly, got it all done in three work days (spread out a bit so I could move everything from one part of building to another so they could work). Did a great job. Much smoother finish than I expected. They protected everything and cleaned up each day. Will use them again. Price was reasonable and they asked extra questions to ensure they were quoting correctly (complex building with two different heights).

USA Insulation applied spray foam insulation to our room addition walls and ceiling and did an incredible job. Forrest quoted us a very fair price and communicated with us throughout the whole job to make it a seamless process. The crew was in and out in one day and cleaned up every bit of their mess. Highly recommend them.

Jennifer Rosendale★★★★★4 months ago

The workers came on time. They did the prep work quickly and efficiently. Insulation was installed properly and they cleaned up everything afterwards. I was very happy with this service.

Kyle Melton★★★★★3 months ago

Justin and his crew from USA Insulation installed their patented injection foam insulation in my home. I was very pleased with their work and would absolutely use their services again in the future myself and recommend them to others. They expertly removed and re-installed my existing aluminum siding with no trace it was ever moved. The guys were very professional and friendly throughout the day, answering all questions I had. They cleaned up well after they were finished, leaving no trace. They even threw in insulating my attic floor free of charge.

Frequently Asked Questions — Spray Foam Insulation in Marion

These are the questions Marion 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 5 verified Marion contractors above for exact quotes.

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