Highly Recommend Koala Insulation – Exceptional Service and Results Koala Insulation transformed my attic by removing old insulation, sanitizing, cleaning, air sealing, and installing new, high-quality insulation. I obtained three quotes for the project, and while Koala wasn’t the lowest bid, their expertise, thoroughness, and commitment to quality made it clear they were the best choice. Gene was outstanding throughout the planning process. He took the time to understand my home and family’s needs, prioritizing both comfort and indoor air quality. He clearly explained every step, highlighted energy-saving benefits, and guided me through available rebates and tax credits—handling all the paperwork with ease. Roberto and his crew were true professionals during installation. They were meticulous, respectful of my home, and kept the interior spotless. The work in the attic was nothing short of exceptional. My primary goal was to eliminate the 5-degree temperature gap between the first and second floors caused by a single-zone HVAC system. After Koala’s work, the difference is now just 1 degree. The improvement in comfort is immediate, and I’m confident this upgrade will significantly lower my energy bills. Thank you, Gene, Roberto, and the entire Koala Insulation team for your professionalism, skill, and genuine care. I couldn’t be happier with the results.

Our company has used Gemini Spray Foam for many years. Their workers are very clean and organized. They protected all windows and home during their spray installation process. I would highly recommend them.

Robyn McAllister★★★★★3 years ago

I used Gemini last year to spray foam the attic of a home I purchased the year before. Spray foam had been recommended to me by people as I had major drafts and uneven temperatures on the upper level and finished attic areas of my house and was not energy efficient and was very drafty. Bob and his team were respectful, reliable and cleaned up well. He quoted me what I felt was a fair price for the job and his crew showed up and answered all my questions and got the job done in the time as promised. Flash forward a year and no more drafts and the upstairs temperature is comfortable and even and no more drafty areas.. I would and have recommended Gemini!!

Great Experience with Gemini! Insulated our project on time in a professional manner. Highly recommend.

Frequently Asked Questions — Spray Foam Insulation in Long Branch

These are the questions Long Branch 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 2 verified Long Branch contractors above for exact quotes.

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