Schedule: Daily 9:00 AM – 6:00 PM
Keeping your utility bills in check is a huge deal for most households. Service Guys tackles this by focusing on energy efficiency upgrades that keep your home comfortable all year long.
Instead of rolling out standard fiberglass blindly, they start with a thorough home energy audit. This diagnostic check pinpoints exactly where your house is losing air, so you only pay for the materials you actually need.
My neighbor used them last fall and loved how clean the technicians kept the workspace. The crew used safe materials and really respected the property boundaries.
But booking an appointment gets tough when the seasons change. Their calendar fills up fast as soon as the weather turns cold, which can push your installation back by a few weeks.

Many older properties suffer from drafty walls, but tearing down drywall to fix the issue is rarely an appealing option. USA Insulation skips that headache entirely by using proprietary injection foam designed specifically for existing homes.
Their approach maximizes your home’s thermal resistance by shooting specialized materials directly into the house’s structural cavities. It’s notable how their specific foam formulation naturally deadens sound to help quiet down noisy street traffic.
Another plus is that their Installation is quick and non-invasive, usually wrapping up without leaving any construction debris behind.
Because this is a specialized chemical application, it does carry a higher upfront cost compared to standard fiberglass. You’ll just need to weigh that immediate financial investment against the long-term structural benefits.
Definitely recommend
Thanks to Clay Morris for coming out and giving us an insulation opinion. We didn’t need any additional insulation and he was honest about it – and could have sold us something we didn’t need. Would definitely recommend him and this company.

We highly recommend this company!
USA Insulation of Nashville removed old, dirty insulation from our attic, sealed around light fixtures, sprayed disinfectant, then installed new insulation (13-14”, R38 rating) over all our living space. The employees were informed, skilled, and thorough workers, (Rozelle, Philip, and Vann), and each was easy to talk to and explained all procedures very well. We highly recommend this company!

Large-scale architectural projects require a totally different level of material sourcing and technical knowledge. As a heavy-duty supplier and fabricator, Specialty Products and Insulation delivers commercial-grade thermal protection for complex developments.
They keep a massive inventory on hand, and their staff easily navigates rigorous technical specifications. The facility also handles custom fabrication for specialized pipes and ducts, guaranteeing an exact fit for unusual industrial layouts.
I actually spoke with a local facility manager who runs several auto repair shops recently, and he highlighted their precise fabrication work.
Just keep in mind that this provider caters mostly to major contractors and industrial clients. If you’re a single-family homeowner looking for a basic attic top-up, their massive industrial offerings probably will not fit your small residential needs.
4. Nashville Spray Foam Insulation

Schedule: Mon-Fri 8:00 AM – 6:00 PM
Getting proper coverage in irregular or exceptionally tight spaces can be a frustrating puzzle. Nashville Spray Foam Insulation tackles those difficult areas by delivering heavy-duty airtight seals using advanced polyurethane materials.
Their chemical applications effectively block drafts and moisture in tricky spots like crawlspaces and low-clearance attics.
By offering both open-cell and closed-cell options, they create a secondary vapor barrier that basic fiberglass batts simply cannot match.
If you’re already scheduling maintenance with local plumbers or water heater repair technicians in a damp basement, sealing the envelope first is a smart move.
But be aware that their chemical curing process is pretty invasive. Property owners usually need to vacate the premises temporarily because of the strong fumes during application.
10/10 definitely recommend this team!
Nashville Spray Foam Insulation did an outstanding job! They were very knowledgeable and helpful with the questions I had about getting my attic insulated. They work swiftly and efficiently! 10/10 definitely recommend this team!

5. Hayes Insulation

Contact: (615) 395-5004
Schedule: Mon-Fri 8:00 AM – 4:00 PM
Sometimes, sticking to the basics is the smartest move for older Nashville homes. Hayes Insulation skips the trendy, experimental materials and focuses heavily on time-tested methods.
My brother recently needed a straightforward attic retrofit and found that this local crew does a great job installing reliable thermal barriers using classic fiberglass batts.
They’re also a go-to for bulk new construction projects while making sure everything meets strict local residential building codes. You get a highly experienced team that intimately understands regional housing structures.
Since they stick strictly to the basics, their traditional approach really doesn’t work for complex industrial projects.
So, if you’re hunting for advanced chemical sealing or heavy-duty commercial thermal applications, you’ll definitely need to hire a different contractor.
Highly recommend working with Hayes
Hayes Insulation did an amazing job for us on our new home build. Very attentive to details, schedule and communication. Working with Glenn was great and he was super responsive and flexible with changes. Would highly recommend working with Hayes.

Before you do it yourself, do yourself a favor and contact Hayes insulation for a quote. I reached out with the dimensions of my garage ceiling to be insulated. I got a straightforward quote back in under an hour and the job was completed the next morning. They were communicative, professional and my garage job was perfect! Would 💯 recommend to anyone looking for pro insulation jobs at a great price!
