We had an all around great experience with Northern Insulation. We had a catwalk installed, complete removal of our old insulation and then fresh put in. The team air sealed the attic and accommodated a few additional requests from us as well. Ryne was very patient and took time to answer all of our many questions. The whole team was very communicative and they did a great job showing up on time, sealing off the house to prevent irritants from escaping the attic and cleaning up. This type of service is extremely rare! Would highly recommend.

They are one of the best you can find. These guys will save you money on your utility bills. Mine went down dramatically and my house is so much more comfortable now even in the summer it stays cooler. Thanks.

I used Sereno’s Insulation to install a vapor barrier in my crawlspace and insulate my foundation walls and sill boxes with closed cell foam insulation. The crawlspace was tight with multiple supports to contend with. The team completed the job without issue. I am extremely happy with the work completed and would recommend them to anyone looking to have closed cell foam insulation installed.

They showed up on time cleaned up and did what they asked in two days. Also, the inspector who came to look at it, complemented their work.

- insulation of my attic was done on 2/11/2022. I paid on the same day. - on 2/12/2022, I informed the company that the lights in the attic is not working - after multiple calls with different people, I learned that the electrical wire was disconnected before covering by the spray foam. The issue is that there are electrical conduit pipes but no exposed wires and the section where the box is sitting that's disconnected is on the inside wall and not roof. I was told that the inside wall won't be sprayed. And I was home the entire time as I requested a call when they were ready to spray to take pictures before they started the work. So they could have informed me when they decided to spray the inside the wall and before disconnecting any wires. - as of 3/7/2022, I'm told the guy will come back and reconnect the electrical line but it hasn't been resolved yet. I have no ETA on when it'll be done. Issue is that I still didn't get clear explanation as to why it was disconnected in the first place since the covered electrical box has 2 electrical conduit pipes and one is still working while the other is disconnected. What I conclude is that if there's an issue or after service is needed, office people will be nice on the phone but won't be able to give any real update as the decision is made by the owner only. So while they'll be nice on the call and promise to call you back, they can't resolve any issue or provide a real solution. To be fair to the work they've done, here are what went right. - they arrived on agreed time and workers were courteous. - they covered everything including floor and cleaned up after the work was done. - based on what I see, the spray work is done well. As of 3/16/2022, I haven't heard back from Sereno's insulation at all. Will update this posting once I hear back from them or have my issue addressed.

Frequently Asked Questions — Spray Foam Insulation in Round Lake Beach

How much can spray foam insulation save on heating and cooling bills in Round Lake Beach?▼
Homeowners in mixed climates like Round Lake Beach, IL 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 Round Lake Beach?▼
For most homes in Round Lake Beach, IL, 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?▼
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.
