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.

These guys were very professional. They did my attic and I could not be happier with the work. Very attentive to detail and the crew were very polite. My wife baked them cookies and made coffee for them. Great experience. Thank you

Haley “Haley Mac” McElmurray★★★★★a year ago

They did such a great job! The improvement in being able to keep it warm in winter and cool in the summer without raising our bills through the roof is astronomical. They got it taken care of quickly, it looks great, and they were affordable. Highly recommend.

Kristin Chapman★★★★★3 years ago

We'd been putting it off for years, but it was time to finally do something about our attic insulation. I heard good things about southern mass spray foam, so I felt comfortable using them. The guys were great even answered my has to know everything hubby's questions. They were done much quicker than I anticipated. It's made a world of difference and I wish we hadn't of waited so long.

I just had JM install insulation at my house. The crew did an 'outstanding' job. Highly professional and courteous. They treated my home as if it was their own. I can't say enough about about their work, their attention to detail and the way they cleaned up the work areas after they had finished. I would definitely recommend them to anyone having their house insulated.

Frequently Asked Questions — Spray Foam Insulation in New Bedford

These are the questions New Bedford 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 New Bedford contractors above for exact quotes.

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