I had Keith insulate my home about a year ago and it was fantastic. The insulation is not cheep but he was excellent to deal with, did a fantastic job and the quality of the material is well worth it. The home is significantly more comfortable, has no air leaks, seems to be generally more rigid and it has a far better R value per inch than other solutions I considered. I am confident this is the best way to have insulated my home and will save money in the long run.

The Neeco Crew 4 - JR, Juan and Ismael had worked the last day 2 days at our Scituate, MA home insulating the attic with duct sealing, propavent, added 6 inch fiberglass batting. They also took care of our attic door in our room over garage with 2 inch thermal barrier and the kneewall with 2 inch thermal barrier as well. Sealed gaps in the bedroom with dormers in the small closets. Crew 4 took care of adding a bath fan hose and a new attic stair cover. They also took care of the exterior doors with free weatherstripping. The energy savings are real even with our 15 year home we built. This crew was professional and experienced in this type of work. Very grateful for the work they did. I recommend them to any homeowner. This will save us $ during the winter and summer for sure. Greatly appreciated!

After the energy assessment gained from Mass Save, my partner and I decided to change some major home appliances like AC, water heaters, Inductions stove from them to reduce energy use. We got rebates and were grateful!

Anytime we had a question or there was a concern throughout the entire project. He was always time when you go with his responses and help guide us through the entire process. We really appreciate having him on the team and can’t stop singing his praises. My husband is the one who actually told me to give him a shout out on your reviews.

Random Stuff with Joe★★★★★2 months ago

I hired OnTime Insulation to spray the inside of my metal garage. They sprayed 2" of closed cell insulation. I received 3 quotes from 3 different insulation companies and they were all close in price. OnTime was the lowest estimate by about $150. They were pleasant, flexible, and did top quality work (see photos). I would highly recommend them and if I ever need insulation again in the future, I will call them first.

Marco and his team helped me in a pinch on short notice and accommodated a time sensitive insulation project. The guys who did the work, were kind and professional, and worked incredibly hard in unseasonably hot temps to get the job done. All while doing it, after there day had already been completed. The only constructive criticism I would provide is— initial communications via email were a bit ambiguous. While Marco and the team made it work, there were duplicative email threads that had different answers and when I was triple confirming date and them, there was no response and I had to call Marco directly. Ultimately, it worked out and I’m grateful for the team but it made the scheduling more stressful than it needed to be. Overall the work was great and the team too, insulation was done well and that’s what matters.

Stellar work from the start with the estimate and options: Marcos provided the best options and worked within my budget. Then came the crew who worked for 2 days, did a fantastic job, and cleaned up. I have had problems with contractors doing poor work and/or running with my money. You can trust OnTime insulation for a job well done.

Frequently Asked Questions — Spray Foam Insulation in Gloucester

These are the questions Gloucester 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 4 verified Gloucester contractors above for exact quotes.

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