I wanted to get an estimate for insulation between my basement and first level to dampen noise transfer as best as possible. I called SLC Connections LLC to leave a message about 5:30am this morning. To my shock the proprietor Ariel answered like he had been up and been working already! He was out at my house by 1pm. He quickly determined I already had insulation in there and did not make sense to add more for the cost benefit of additional Insulation. Super service and nice guy! Give em a call if you need any insulation work!

We had the crew over for an attic insulation job and they were on time, great pricing and wonderful to work with. I’d recommend them to anyone

I recently bought a home that was missing insulation over the master bath and closet of which it was chillfully obvious when you were in those rooms and outside temps were in the 30s. After debating on doing the job myself, I simply didn’t have the time with work and other things going on, so I Googled companies to do this for me. There were a couple options with reviews that had a “5.0” rating, but for whatever reason, Ariel was the only one that called me back after requesting a quote, and I didn’t wait long for that call! Ariel came out a couple days later and we talked about this issue, but also discussed putting insulation over my garage which I was debating on doing anyway, but we also talked about the state of the rest of the house of which I knew things weren’t amazing as I could see an insulation measurement up in my attic that seemed way lower than I was expecting on a 10-year-old home. He took a lot of measurements, got up in my attic, and we talked some more about my options. He left and promised me a quote with a few options for my consideration which I received that evening. I opted to go all in and insulate my garage and add additional insulation to the entire house since everywhere else was around R30. Now my house is at R60 (totally my choice, but it wasn’t that much more than bringing things up to R49), and we did R38 over the garage. Also, Ariel’s team ensured I had the necessary baffles where they were either missing or not high enough for the added insulation, and they fabricated some retention barriers where portions of my ceiling is vaulted to keep things in place. There was a minor communication error during the process (unique to my home’s situation), but it was addressed quickly and certainly to my satisfaction. Frankly, I’m more impressed with companies that deal with hiccups or problems and make things right than companies who dismiss the issue and leave you hanging. I have no reservations with recommending SLC Connections for your insulation needs. Ariel was great, the people that came out were great, the job looked like it was done well after completion (I’ve been scammed in the past on insulation, so you better believe I was back up in my attic to verify things after the job was done), and I am happy with the end result in my master bathroom and closet! It now feels warm like anywhere else in the house!

I wish I would have called Insulation from Hale first. They were the first company to pick up the phone out of 5 companies I called. They were 4 on my list. From the first phone call, they were understanding, explained processes in detail and worked around our schedule. We called them 2-3 weeks out and told them we had a small window of time to work with and they fit us in their busy schedule with an even shorter notice. I wish my pictures did the justice as the work looked amazing and worth the cost to have our garage insulated during the build process. Both Brian and Rob were responsive and their team was very professional, I will call them for future needs and refer them often as I know they will take care of their customers.

ROBERT WICKERSHAM★★★★★2 years ago

Good people to work with. Both Jeremy in sales and Jessie the installer answered all my questions and concerns. Great job.

Dave Dorsey★★★★★8 months ago

We had a great experience with Insulation by Hale. Communications was very responsive during the bid process and Dayan followed up with us after the work to check on how it went. The crew, George and Noah, were great to work with and did an excellent job on our basement insulation. They helped us understand the process, let us inspect the foam before adding the batt and thoroughly cleaned everything up afterward. Their price was very reasonable, too. I wholeheartedly recommend them!

Highly recommend USI,,salesman Gregory was Awsume to work with,,, he was the only insulation salesperson to tell me about the rebate on doing basement walls. So happy with them.

Parker Jackson★★★★★2 years ago

Amazing Experience! Worked with Cody and Chris, who were very professional and did an amazing job touching up the insulation in my new home. The original contractors (not USI) had missed several spots and the temperature in our home would vary significantly from room to room. Cody and Chris came on time and were very careful to ensure that they didn't leave any mess. They touched up the insulation and even put in a bit extra to ensure that we wouldn't have any issues. I will definitely be using USI for any future insulation services.

I hired USI to insulate my garage and they did a fantastic job. They blew in r38 in the attic and filled the walls. The walls are sheet rocked so they cored holes and blew the insulation into the cavities. Great price from RJ and the installers were friendly and professional. They left the garage cleaner than it was when they arrived. I will definitely use them again

I was going to give them a 2 star for losing the key to the truck and blocking me in my driveway so that I was late for a work meeting, but the service was incredible. Amazing job. My workers were Andre and Jose. Not quite sure if that was their names. Great job by them

Zeev Godina2 years ago

Never used the service an never will was pulling into a restaurant and was almost slammed into by a driver and he got physically aggressive shouting racial slurs. Glad to see the kind of people they employ and how they conduct themselves in a company vehicle.

My experience with this company was pre-Covid.. the job was done in order to create a sound barrier between 1st floor and basement in an older home.. the company's rep came out to give me his opinion.. he initially told me that it would work and also that it would only be a minimum of 6 holes in ceiling.. I will honestly say, his superior could not guarantee that it would help.. now i know why...an insulation company of this size and experience, would know that this type of insulation is not recommended for soundproofing.. he knew and should have recommended another product... this review should have been written 2 years ago..why know? do i expect to get my 527 dollars back? No..(and boy do i feel stupid for paying)...in short, the reason Im taking a minute to write this is because every time i look at my ceiling in my living room and master room I see a total of 48 holes..(boy do i feel stupid).. it'll cost me a 1000 to patch holes.. could you imagine the mess of pulling down ceiling to replace, not to mention cost. (and boy do i feel stupid).. so please ask the right questions!! these representatives took advantage of ignorance.. its too bad that in this climate that we live in, we still can't trust.. thanks, too mad to look up..

Frequently Asked Questions — Spray Foam Insulation in Salt Lake City

These are the questions Salt Lake City homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 37% typical energy savings. Compare the 5 verified Salt Lake City contractors above for exact quotes.

Why is spray foam insulation especially important in cold climates like Salt Lake City?
In cold climates like Salt Lake City, UT, proper insulation is critical to preventing heat loss, ice dams, and frozen pipes. Spray foam's air-sealing properties stop the cold air infiltration that traditional insulation cannot address. It also prevents the moisture buildup inside walls that leads to mold in cold-weather freeze-thaw cycles. Homeowners in UT typically save 25–35% on heating costs. Note: in tightly sealed homes, proper mechanical ventilation is commonly recommended to maintain fresh air exchange without losing the heat you've paid for.
Does spray foam insulation prevent ice dams in Salt Lake City?
Yes — spray foam insulation is one of the most effective solutions for preventing ice dams in cold climates like Salt Lake City, UT. Ice dams form when heat escapes through a poorly insulated attic, melting snow that refreezes at the eaves. By creating an air-tight thermal barrier in the attic, spray foam eliminates the heat loss that causes ice dams in the first place.
What R-value do I need for spray foam insulation in Salt Lake City?
For cold climates like Salt Lake City, UT, the Department of Energy recommends attic insulation of R-49 to R-60. Closed-cell spray foam provides R-6 to R-7 per inch, meaning 8–10 inches achieves code-minimum performance. Open-cell foam at R-3.5 per inch requires greater thickness. A local contractor familiar with UT building codes can recommend the exact specification for your home.
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 in Salt Lake City, UT?
In Salt Lake City, UT and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. 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 in Salt Lake City costs $2,000–$6,000. Most Salt Lake City 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 in Salt Lake City, UT?
When searching for a spray foam contractor in Salt Lake City, UT, look for ones 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 Salt Lake City 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 in Salt Lake City 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.
