Dom and his crew showed up promptly and introduced the ‘dream team.’ They certainly were! They insulated our walls and attic and were efficient, respectful and informative.

Did great work insulating a few odd areas around the house. The spray foam crew managed to get above and down the side of an attic shower we didn’t demo. The cellulose crew was efficient. Everyone was personable, flexible and professional

We recently had home insulation installed by McLaughlin and Williams through the MassSave Program. We could not be happier with this company. Our first introduction with Noreen Sheridan, owner of McLaughlin and Williams which is a family owned business, was warm and welcoming. Noreen was extremely helpful with scheduling, guiding us through the process and keeping us informed and up-to-date. Her crew was courteous, professional, dependable and thorough. Her foreman, Jay Pinto, never left each day without informing us what work was accomplish that day and what work would be performed the following day. The walls that needed to be insulated from the interior were left in conditions where only paint needed to be applied. They went above and beyond and finished the job in exactly the six days that was told to us at scheduling. I highly recommend McLaughlin and Williams and can't thank them enough for a job well done!

McLaughin insulated our house through the Mass Saves program and did a great job. The crew was great to work with and took the time to customize the work order once they arrived. Work we got done: -Blow-in cellulose insulation -Insulating sunroom floor -Insulating sunroom ceiling. A picture of the sunroom insulation is attached (the sloppy purple foam work in the background is mine).

Not only did these guys have the earliest availability than the three contractors I shortlisted through Mass Save, but they worked around my work schedule and holiday travel plans to do my whole house insulation project - which I really appreciated as winter was just around the corner. As other reviews mentioned, Curtis and his crew carefully protected our (brand new) hardwood floors with lots of tarps, threw plastic over furniture and vacuumed after each day of work. Our home feels so much warmer and I am already seeing savings in my gas bill! I couldn't be any happier with their work.

We recently worked with Polar Bear Insulation after a Mass Save assessment recommended several energy-saving improvements, and we couldn't be happier with the results! They sealed our attic, added a new gable vent, installed 14 inches of fresh insulation, and even built a 2-foot-wide catwalk for easy future access. Peter, Steve, and Curtis were fantastic—professional, friendly, and true experts in their field. They went above and beyond, carefully protecting our home with tarps and plastic to keep everything clean during the process. The workmanship was top-notch, and the difference is noticeable—our home feels so much warmer now! We highly recommend Polar Bear Insulation for anyone looking to improve their home's energy efficiency. Thank you for an excellent job!

We're having a lot of renovations done on our home. Of all the contractors we've hired, Polar Bear insulation was among the best. They were hired through Mass Save. I highly recommend. They were courteous, punctual, did great work, and did a fabulous job of cleaning up after himself.

Frequently Asked Questions — Spray Foam Insulation in Lawrence

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