I recently re-engaged Coastal Spray Foam for another residential spray foam project. Joshua is extremely knowledgeable, responsive and competitive. He showed up at the agreed time and completed the project timely. Furthermore, unlike some contractors these days, he made sure our premises were broom clean before he departed. I highly recommend Coastal Spray Foam to be part of your insulation conversation.

Scott and his team did an amazing job. I had pipes that were freezing in the winter due to lack of insulation and he came out with thermal cameras and was able to locate exactly where the cold air was getting in. He insulated inside the wall and also insulated the pipe and we haven’t had any issues since. Thank you guys again!

Nick and his team did a great job on the insulation of my attic and bedroom. Nick is very thorough and willing to take his time to explain things.

Mary Hutchison★★★★★a month ago

Nick, Robert, Ron, Orion are all extremely professional, respectful, committed to the job until fully completed. Upon arrival Nick reviewed the initial work summary with us and did a second walk through to verify all was in order. Upon completion Nick let us view the attic. He had a final summary of the work completed for us. He directed us to a tax form to submit with our tax return. Through out our communication with Nick he continously asked us if we had any questions or concerns. We highly recommend NM Energy Enterprise and will use again in the future for our needs.

Ashley and the guys @ The Insulation Guys did an absolutely incredible job for us start to finish! We inquired about having our crawlspace encapsulated and spray foam insulation done as well as laying down a vapor barrier. Ashley came out immediately and provided an aggressive estimate, and followed up answering all questions and any concerns we had. They came out to perform the service and had an equipment issue initially, but we're able to remedy the issue and return to complete the service quickly and with clear communication throughout the exchange. Overall they did an amazing job, had great communication throughout, and they weren't happy until we (the customer) were happy. I wish more service businesses delivered the level of customer service these guys did. Will be working with them again on all of my future projects including my garage, and shed. Thank you guys soo much!!

The Insulation Guys were great to work with. I hired them to insulate my barn with closed cell spray foam. Kyle was accessible and communicated well. He was knowledgeable and had great suggestions. He and his employees were professional and motivated to do the job right. I'm glad I chose the The Insulation Guys and would recommend them.

Mike, my Sales Representative, looked over my attic and provided clear findings and solutions to my insulation needs. He stayed in constant contact for the short duration it took to schedule my job. The two technicians, Randy and Donovan, were absolutely wonderful.They explained the process and answered all of my questions and concerns. Yvonne in the office was friendly and made the payment process very easy. Could not have asked for a better experience. And, I will enjoy a more comfortable home from now on!

Momper did a great job on our blow-in insulation job. The house is several degrees warmer after the job. Keith, the sales rep, was awesome and the crew that did the work was courteous and professional. Yvonne in the office is very nice. Glad we went with Momper!

JC★★★★★2 years ago

Was really happy I found this company. Got a free inspection quote to replace and fix some of the insulation in the attic and Ryan found black mold on top. Couple hazmat suits and a few hours later the mold was gone! The next day they fixed the insulation and a few other things I needed done! They cleaned up well and did a great job. Would honestly recommend them to anyone needing anything insulation related!

Frequently Asked Questions — Spray Foam Insulation in Gary

How much can spray foam insulation save on heating and cooling bills in Gary?
Homeowners in mixed climates like Gary, IN 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 Gary?
For most homes in Gary, IN, 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?
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.
