I called several local spray foam companies, only one called me back, not only did they call me back but they came and did the job when they said they would. Even better, the guys were professional clean, and did the job in a day. I would highly recommend spray Foam Genie of Reno to anyone Who wants a professional spray job

Jeremy Riesenburger★★★★★7 months ago

We couldn’t be happier with the job Joe and his team at Spray Foam Genie did on our 40-foot school bus conversion. From start to finish, they were incredibly professional, personable, and communicative. They took the time to understand our vision for building a four-season home on wheels and executed it with precision and care. Their attention to detail was obvious in every nook and cranny they covered, and now we’re confident that our bus will be comfortable no matter the season. It’s rare to find a crew that’s this skilled and also just genuinely great to work with. Highly recommend Joe and his team to anyone looking for quality spray foam insulation done right.

Joey Bayne★★★★★9 months ago

Joe and his crew were very professional and hard workers. Joe had great communication and they went above and beyond to make sure we were happy. Their work was excellent and they made sure our home was left clean. We will definitely be calling them again on our next projects.

We had an exceptional experience with Sierra Air! They answered the phone, set up an appointment right away, offered us many options and also gave us a free upgrade when one unit was not available. Our heater went out over the holiday week and Felipe, Louis, and Jack worked on New Years Eve day so we would have heat for our houseful of guests. Max did an amazing job designing an efficient and high quality system. We highly recommend Sierra Air!!

A Zer★★★★★a month ago

We had a wonderful team install our system led by Alex. What a fantastic experience. From the minute he came to our house we felt comfortable with his skills and mastery of the installation. Best of all he had a really fine sense of aesthetics and a respect for the customer. I would never consider anyone else for HVAC needs as a result of my experience today. It’s very difficult to find the right combination when you suddenly have to make a decision quickly and trust it will go perfectly. Alex professionalism and great disposition made it all go better than I could have expected. From the beginning to the end, what was most important to him was a job well done and a happy customer. He was willing to take whatever measures possible to make that happen. He was an easy person to partner with because he listened and had excellent high standards . He and his team member Tim did well and we got the great benefit. One in 1 million.

First off, as someone who runs a service business myself let me say I was very impressed with the level of service and professionalism I experienced with Sierra Air. Communication was excellent. I received text reminder from the office with a picture of the technician with his name when he was on his way, the technician called when he was 20 minutes out, showed up as expected, vehicle was clean and presentable. The technician introduced himself, put shoe covers on prior to entering my home and went to work. After diagnosing my furnace the technician explained the issues to me in understandable terms allowing me to make a educated decision to replace my furnace. Donny, the design consultant came the same day to help me choose the right system, crawled under the house and inspected the ductwork, did the necessary calculations to determine the proper size furnace for the square footage of my home. From the first phone cal, everyone I dealt with delivered a excellent customer service experience. I highly recommend Sierra Air

Have worked with a few wools at this point and this is by far my favorite. The batts are insanely easy to work with, a joy really, and the customer service is awesome! I’m stoked to report I have never seen any poor sheep skin on any of their product like I have with some other companies i have gotten wool from. All in all a great company!

Tim Annin★★★★★5 years ago

We highly recommend Havelock Wool! We're very glad that we bought the insulation for our van build from them! Their wool is great to work with - it's all natural, doesn't irritate skin, is easy to work with and is exactly what we were looking for on our build. Beyond an excellent product, they have great online resources to determine quantities, installation methods, etc. Their team was responsive and great to work with. They were able to meet us for pick up on relatively short notice and couldn't have been more accommodating. Thanks Havelock team for a great experience!

Taylor Musselman★★★★★5 years ago

Great company - friendly customer service, easy to communicate with. Loving the wool in my van for insulation.

Jim Orsi★★★★★6 years ago

Excellent work by Arturo and Jose! I just can't say enough about the quality of their workmanship. They blew in insulation in my garage ceiling since our house didn't have any. You can tell they've done this a few times :) Highly satisfied and wouldn't hesitate to call them again in the future if need be. Also kudos to estimator Dave Sandunsky for great customer service.

Dekon Brodie★★★★★6 months ago

Luis is very prompt and professional. Got me my estimate right away and his crew was able to do the work same week. Love the quality for a great price

Amy★★★★★3 years ago

As owner-builders, we are thrilled to be able to write this review for Alcal Specialty Contracting. First, the professionalism from the initial call to the estimator to the installers - the service was second to none. Rich, the estimator, prepared a fair quote for the services being provided; Todd, the Supervisor, communicated with us every step of the way, but the genuine surprise was the professionalism and quality of service supplied by Bryce and James. Several contractors have not truly cared about providing top-notch service to a one-off home build. But, it's clear Alcal cares about customers regardless of job size. Thank you for exceeding our expectations. We wholeheartedly provide this review because Alcal has earned our full-throated support. Thank you.

These guys are great, they bent over backwards to fulfill all my insulation needs. The previous guy's review looks unfair as the guy is only complaining about getting lost in the parking lot.

They performed insulation of 2 walls to tone down noise of the house for a bedroom. They came on time, worked performed professionally and did a fantastic job!! Highly recommend this company!?

Michelle Smith★★★★★4 years ago

The entire process was flawless. Rick came out when I called to go over what our company was looking to get done. He kept in touch with me every step of the way. When the crew showed up they got right to work. Great group of guys; professional and efficient. They were able to get the job done ahead of schedule and the gutters match our building perfectly. A nice upgrade to our property. Thank you!

Greg Sayabalian★★★★★2 years ago

Rick and the crew were great, once I accepted the bid they were there the next day. I even got a discount because we didn't realize I had some insulation already in certain areas. Very professional, fast and efficient work. Thanks again to Rick and the Gale crew, highly recommend. Greg S

Frequently Asked Questions — Spray Foam Insulation in Reno

Does spray foam insulation work well in hot dry climates like Reno?
Yes — spray foam is highly effective in hot dry climates like Reno, NV. While moisture control is less of a concern than in humid climates, the air sealing properties are critical for keeping hot desert air out and cooled air in. In extreme heat climates, an unsealed attic can reach 150°F+, dramatically increasing AC load. Spray foam in the attic can reduce attic temperatures by 30–40°F.
What is the best area of my home to insulate in Reno?
In hot dry climates like Reno, NV, the attic is typically the highest-impact area to spray foam insulate. Desert sun heats roofs to extreme temperatures, and an uninsulated attic transfers that heat directly into your living space. After the attic, crawl spaces and rim joists are the next highest-impact areas. A local contractor can perform an energy audit to identify where your home loses the most 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.
