We worked with Insulright on insulating our new home addition and remodeled home. They were beyond fantastic to work with from the time of scheduling through the installation. James worked with us to determine our needs and recommend a strategy and was on top of everything from start to finish. Nate, the foreman, was incredibly professional and thorough. They accommodated our schedule and timeline and could not have been more fantastic during an otherwise stressful renovation! I would 100% use them again and recommend them to all our friends and family.

I had Insulright of North Versailles apply both open and closed cell foam to my home. I had completely gutted the house to the studs so they had access to every inch of the old farmhouse. This company is incredible from front to back. From Joe who came out and gave me a very competitive bid, to John who handled my account, to the work crew (Chris, Alex and the guy who didn’t talk much.....) all incredibly professional and able to adjust to what was appropriate for my house. They were on time every day, cleaned up constantly after themselves and made sure I was satisfied. They should be very proud of the team they have assembled. And the product itself is amazing. My house is tight now with no air gaps and easily heated. I highly recommend them. Do yourself a favor and at least let them give you a bid. You’ll be glad you did.

I should of wrote this review a while ago. Just over a year ago, I had James from Insulright come out and visit for an estimate. We went with them to insulate are entire home from basement, every wall in between, to garage roof. The guys were all friendly and worked hard. And the quality is unmatched! My energy bill is almost cut in half, and it’s very soundproof from noise’s outside. It’s worth every penny we paid. Don’t even think twice verses traditional fiberglass insulation. There’s no comparison. Totally exceeded my expectations. Thank You for the quality service! Ligonier Project.

I would highly recommend Insulwise if you are looking to fix your attic insulation and air flow. We felt the difference on our second floor immediately! No more drafts! Insulwise sealed our attic, fixed our roof ventilation, cleaned areas of mold and blew insulation in. It really was amazing how quickly we felt the difference. The production team of Brian and Justin were great too. Very clean and kept me informed the whole project. Love that they take pictures! Thank you Insulwise. Would definitely use you again.

Packed exterior walls full of treated insulation, insulated basement crawl space, and spray foamed all exterior basement ceiling joists. Two days of work with a three man, then two man, crew. Could've used one more day considering the lack of adequate setup on our part (contact me Insulwise CSR ~ we'll chat). The overall vibe... Courteous sales and installation crew, reasonably-priced, did what they could with the space we have (old house, tight, awkward quarters, who knows what they'd come across), and final product turned out great! It's only day two, and already our furnace is starting to run less and there's a different kind of quiet in the house where previously it felt open and drafty. We still have some post-cleanup and glow up to do. Don't be fooled by the promo videos... this is MESSY! You will need to board or crate your animals. You will need to remove more than you think from your walls if getting exterior blown-in insulation. Even though the team does a pretty amazing job of cleaning up, there's still no getting around the post-project clean up. Be ready to fix up and paint the holes, too. That's an entirely different situation (again, Insulwise, let's chat) Considering my walls and basement are now insulated, are all holding at a consistent temperature, and I can already feel difference, it feels like a worthy trade off. Thanks Brian, Paul and Justin for your hard work, time and effort. So far, so good!

Just had Brian, Justin, and Paul here to put dense-pack insulation in my first floor walls. They did a great job, worked hard, were personable and professional, and communicated through the whole process. My house is 105 years old, and a number of the stud bays had zero insulation. Before they had finished with half of the bays, I could tell a positive difference in temperature and draft. We have mini splits to heat/cool our house, and the last two winters they have struggled to keep up. We've had to use space heaters to supplement, and even then I've come down to the first floor being 55-58 degrees. Now, the temp is rising quickly, and the whole floor feels evenly heated. This is a massive difference from what it was. I'm looking forward to seeing the year-over-year on my electric bill. Beyond that, our house is close to the road, and traffic noise has disappeared. Before selecting Insulwise, I was considering a foam option. After looking into the pros and cons, I chose dense-pack to avoid moisture/shrinkage problems with the type of foam that used in existing walls has. Between Brian, Justin, and Paul's professionalism and the guarantee on the insulation not settling, I am extremely confident that I made the right decision. I'd highly recommend them.

We had 2" sprayed under our slab and then had Steel City come back after we installed PEX and concrete to apply 2" on the wall and 3" on the roof panels. Same crew both times. On time both visits and left the garage cleaner than when they arrived. Kudos to Jackson and Gerald! Extremely satisfied with the end product. Our building contractor and concrete contractor were duly impressed with Steel City's work. We highly recommend Steel City Insulation!

We own an older home and we wanted to utilize our cold spaces under our porch. We were told it would make our entire basement warmer & our kids games & holiday decorations wouldn't smell like mold !! It's been months and they were absolutely correct!! Everything is dry& the space is a great addition to our home! Not to mention they did it in professional manner, no mess to clean up on our end. Thanks for your service & honesty

I truly wish I could give them 10 stars, good evening, my Shawn and his crew came to do insulation and other repairs as part of the weatherization program, they were so respectful and did a amazing job, they treated me just like a paying customer. Were so nice and kind and explained everything they were going to do, in my opinion they went over and beyond, their work was truly immaculate, I will never ever forget Shawn, the nicest people each and everyone of them. The big boss came to check their work and he was sooo sweet,and kind, I have told everyone I know about this company, 10 STARS

Jeff and crew did a great job with our warehouse insulation. The results are night and day. Employees were courteous, and work got done on schedule. Would highly recommend.

Karen Schwab★★★★★2 months ago

This is the second time I have used TrueFoam insulation. They foamed a garage ceiling in a rental, and then in my home. I have found them to be the best reasonably priced after obtaining 3 bids, on both occasions. They do a very good job, and hey leave the job site, very clean when they are done. The workers are very polite and timely. If needed I would use them again.

I can’t believe how quick, efficient and thorough these gentlemen were that came to our house. So polite and cleaned up after themselves great as well. Our home definitely feels more sound proof, tight and we can’t wait to see what difference this makes for our bills. It was the perfect solution for our 1904 home.

Frequently Asked Questions — Spray Foam Insulation in Pittsburgh

These are the questions Pittsburgh homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 35% typical energy savings. Compare the 6 verified Pittsburgh contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in Pittsburgh?▼
Homeowners in mixed climates like Pittsburgh, PA 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 Pittsburgh?▼
For most homes in Pittsburgh, PA, 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 in Pittsburgh, PA?▼
In Pittsburgh, PA 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 Pittsburgh costs $2,000–$6,000. Most Pittsburgh 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 Pittsburgh, PA?▼
When searching for a spray foam contractor in Pittsburgh, PA, 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 Pittsburgh 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 Pittsburgh 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.
