Short story: Highly recommend! Professional, competent and a pleasure to work with. Longer story: Estimate was clear, timely and very reasonable. Judy was always lovely to talk with while scheduling our project. Joe went above and beyond before the project to make sure we understood what he was doing and why it needed to be done. He explained possible alternatives and risks/benefits of each choice. Joe has to be one of the nicest and honest people you will ever meet, you can tell he takes pride in his work. Not only did he do a great job on our radon mitigation system (brought our level down to ~0.5pCi/L) but also painted it to make it aesthetically appealing. As an added bonus, he painted a few other things to match. He even gave us some other useful homeowners tips. Truly enjoyed having him work in and on our home.

Big Mountain is the best in the Valley! Judy in the office was a gem to work with. Easy to contact and knowledgeable on the process. Joe in the field is a true professional. He is prompt and courteous, and he was easy to work with. Joe showed great patience as he explained to us the process, and went above and beyond with his service. We are extremely pleased with this installation and would recommend Big Mountain to close friends and family all day long. Hands down.

I was recommended Lilienthal Insulation Company from a friend after receiving really great feedback. And I can't express how happy I am with their service. I contracted them to install sound proofing insulation for my basement project and I am super happy with the results. First of all, and arguably most importantly, the whole job, quoted and installed ended up being cheaper than if I would have gone and purchased the products and installed them myself. So I ended up saving money by getting the job done right, not to mention as a DIYer I couldn't have done nearly as good as a job as they did. Second of all the team (Scott, Jamil) are incredibly helpful, detailed, professional and friendly. The professionalism of the team is second to none. Jamil was able to work around some unmovable items and did so without hesitation. Third, the project was done in a day, and with my short time-frame, was able to get the project scheduled very quickly. Their ability to work with my short timeframe was appreciated and is a great testament to their professionalism. I am delighted with their service, and thoroughly recommend them to anyone. Thanks again. I am looking forward to getting my garage insulated next.

Had them install R30 between upstairs floor and downstairs ceiling. They did a great job and cleaned up after themselves. The initial consultation was great, and they shared knowledge and explained things beyond just regular insulation.

Lilenthal was up for the job when no one else was. We live in an old 117 yr old house with insulation that needed updating. We had a layer of wood chip insulation with old rockwool on top and then fiberglass foam pieces on top of that. The last update was from the 1960s so the old stuff needed to be sucked out and replaced. We purchased wool batts from Havelock Wool that we wanted in place of that. They sucked it all out (which is a nasty job) and did a great job then came back and installed the batts. I’m so glad they were available and didn’t try to push spray foam like the other insulators. It was not an easy job, but I’m grateful they were up for it. Highly recommend.

Spray foam and batt insulation - Denise and Joel have been a pleasure to work with. Extremely patient with unforseen changes in our schedule. On time and professional work done. I would recommend them.

We used Taylor to spray foam our house for a flash and batt insulation plan. I don’t have a complaint about the quality of the foam or the coverage. I understand there are sometimes spots missed or spotty coverage. My gripe is with the customer service. We have a really bad condensation problem where the spray foam meets the fiberglass batts on the ceiling. I’d like to emphasize that it is really bad. I called them and was told they would discuss it with an expert within three or four days. I called again the following Monday. They (Joel) then said we ought to have a look at the situation and that an estimator (Kurt) would be out to look at the project. Three phone calls and a week later, still nothing. No attempt to contact me and no plan to move forward. So I called two other builders, a spray foam company and our real estate agent. The consensus was that I’m wasting my time trying to get Taylor Insulation back out to my place to do anything. Apparently my frustration is shared with others. The other insulation company knew right away why the problem was happening and said they weren’t impressed with the advice I’d been given either. So if you’re hoping for custom service or a company who will stand by their work and make sure you’re getting a good product in the end, look elsewhere.

Taylor installed insulation in my basement. The next time I went down there all the insulation had fallen off the walls and was lying on the ground. They had just covered the vents with insulation instead of making cutouts so vents could be opened. To fix the job they want $420.

Frequently Asked Questions — Spray Foam Insulation in Kalispell

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.
