I called Shoreline Spray Foam because I needed my attic insulated. From the very beginning Rob was fantastic. He came over, looked at my attic, told me what I needed and what I didn't (which goes a long way these days). Rob and his crew were not only top notch as far as service and cleanliness but, he was very fair on his pricing. My home is 70 years old and much warmer already. I can't thank Rob enough. I would give 10 stars if I could! Highly, highly recommend!!! Btw, I never give reviews! Rob and his company surpassed my expectations.

I write very view Google reviews, but feel compelled to share my experience with Nealon Insulation. Nealon did an attic insulation and duct work upgrade and installed gable vents. From beginning to end, the team at Nealon exhibited an extraordinarily high degree of professionalism. Each step in the project was handled with care and attention that always went above and beyond the norm. The team, which included Dave, Chris, Danny, Adonis, Isaiah, Alberto, Alfonso and Jen, coordinated extremely well within their group as well as with me. From the many conversations with Dave in laying out the project, to the site management of the project by Chris, everyone was fully informed and aware of the project’s requirements, its deadlines and my expectations. Most importantly, the quality of their workmanship was excellent. Finally, special recognition to Jen for coordinating the logistics of the project and communicating in a way that kept everything moving ahead very smoothly. Based on my experience, I can highly recommend Nealon Insulation.

Lynn E.★★★★★a month ago

We had a positive experience with Nealon Insulation, and chose them because they are a local business with years of expertise. Their team was professional, knowledgeable, and responsive, making the process seamless. They even helped us navigate the state energy rebate application. The attic insulation installation exceeded our expectations - the team was courteous and thorough, and they went above and beyond to safely and neatly reinstall the plywood flooring. We recommend Nealon Insulation for excellent service and expertise.

Excellent! Ricky is a gem. It's difficult to find good, honest contractors these days. He did an excellent spray foam job in my basement, primarily for energy efficiency and rodent deterrent. He gave sound advice, was punctual and cleaned up after the job was finished. I highly reccomend lighthouse for your spray foam needs. Yvonne R.

Frequently Asked Questions — Spray Foam Insulation in New Britain

How much can spray foam insulation save on heating and cooling bills in New Britain?
Homeowners in mixed climates like New Britain, CT 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 New Britain?
For most homes in New Britain, CT, 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.
