I recently had insulation installed in my attic over the garage and the difference in heat retention is amazing! The cost was very reasonable (Chandler came out in a timely fashion to give me an estimate) and Ms. Bowen/ the installation team were so nice and professional. They found a snake skin in the attic while they were working and made sure they told me when the children weren't within hearing distance in case that might frighten them; a simple thing but I really appreciated their concern! A special thanks to them for a job well done!

I want to give a big shout out to Mr Josh Hoffman for doing such a wonderful job!! He came out and did a fantastic job after the sewer backed up causing me to have to redo all walls and insulation. He was so patient because my child was a 21 question every few mins he did great about not making or leaving a mess and had the best price around when we are ready for the ceilings and underneath he will be the one I chose. I would recommend him over any others around here because of his honesty, his patience and his professional.. Thanks Josh I appreciated everything.

Great experience! In my 30 years as a project manager, I aspired to the “triple zero result”: 0 incidents, 0 delays, 0 cost over-runs. Jeremiah and Energy Savers nailed all three on this turn-key job for me. (Removing and reinstalling aluminum ceiling, foam insulating under sunroom) Highly recommended!

Energy Savers insulated our new barn workshop and apartment above. The owner Jeremiah was great to work with and their pricing was very fair. The guys that did the job, David and Tyler , were awesome. They made sure everything was covered before they began and made sure to seal every possible crack. I highly recommend using spray foam (nice and warm and quiet!) and having Energy Savers do your install! Thanks guys.

I hired this company to spray foam insulation between the logs of an old log cabin, iron restoring. The price was reasonable, they showed up on the schedule day, and the team was personable and very hard-working

Frequently Asked Questions — Spray Foam Insulation in Johnson City

Is spray foam insulation a good investment in Johnson City?▼
For homes in mixed-humid climates like Johnson City, TN, spray foam is typically an excellent investment. The combination of hot summers, cold winters, and significant humidity means your home faces insulation challenges year-round. Spray foam addresses all three — providing thermal insulation in both seasons while controlling moisture infiltration. Most homeowners in TN see payback periods of 4–7 years. As with any tight building envelope, ensure your home has adequate mechanical ventilation to manage interior moisture.
How does humidity affect spray foam insulation performance in Johnson City?▼
In mixed-humid climates like Johnson City, TN, moisture management is as important as thermal performance. Closed-cell spray foam acts as a Class II vapor retarder, preventing moisture from infiltrating walls and attics where it causes mold and structural damage. This dual function — insulation plus moisture control — is why spray foam outperforms traditional insulation options in TN's climate. However, because the building envelope becomes tightly sealed, proper mechanical ventilation is strongly recommended to allow interior moisture from daily activities to escape without losing conditioned air.
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.
