Josh came to give me an estimate 1 day after contacting GTG and the installation of my attic insulation was done within a week. Tony, Dwayne and Josh came on time, did a great job installing an additional R-30 blown in attic insulation and cleaned up afterwards. They installed rulers to show the depth of the additional insulation and covered the pull down attic with a zippered hatch to keep the heat out of the house. Couldn’t be happier with their professionalism and the finished results. I would highly recommend GTG Insulation to anyone’.

We were referred to GTG by our favorite guy to check for mold and he was not wrong! The appointment was set up in a reasonable timeframe, Josh was so easy to work with. Dwayne & Tony worked hard and they cleaned up after. We got lots of pics from Josh after they removed the old insulation. Hubby was home and got to go check out the new product and was pleased. 10/10 would hire them again and refer them to anyone I know!

We used GTG 11 years ago and again today as Stephen and Josh W came to clean our gutters and install new gutter guards because they provide excellent service. Joshua Dubose was also wonderful to work with. We will use them again without hesitation.

CLASS ACT!!! Looked for a company to do spray foam in our attic over the garage which we are converting into living space. (about 400 sq ft) After quite a few quotes we decided on Synergy. They were friendly, personable, reasonably priced, and came up with a great option for spraying the floor cavity which no one else had recommended. When our install date came they had an equipment malfunction so we had to reschedule. The next few scheduled dates (over the following week) also had to be rescheduled as it was taking longer to repair their machine however through that they communicated and were easy to get in touch with. Ultimately they had to get their hands on an alternate machine since the repair on theirs was taking longer but as soon as they did that they arranged to come out and get the job done. What was impressive was that arrangement was Friday evening and Saturday Morning. I am positive this is not their normal working hours but I was impressed that they took the initiative to fit me in at these odd times. Thanks Todd and Justin!!!

Curtis and Ron were prompt and went straight to work. They took extra care in preparing my house with drop cloths protecting my dark printed carpet. They were thorough and very professional. I was extremely happy with the cleanup. Ron and Curtis did a wonderful job. I especially love the attic access cover; I no longer feel a draft coming from my attic. Great job!!

Ryan Ward★★★★★a year ago

Frequently Asked Questions — Spray Foam Insulation in Columbia

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?
Spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your location. 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 costs $2,000–$6,000. Most 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?
Look for contractors 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 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 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.
