When you need a spray foam insulation contractor in Putnam, CT that gets the job done right the first time, Lamothe Insulation & Contracting is the team to call. Our crew handles everything from spray foam and blown-in insulation to full insulation removal for homes and businesses across northeastern Connecticut. Whether you are building new, retrofitting an older home, or addressing drafty rooms, we bring the experience and equipment needed to keep your property comfortable year-round.
Putnam's winters can be brutal, and homes built decades ago often lack the insulation needed to keep heated air inside where it belongs. Our team sees the same problems on job after job: thin fiberglass batts that have settled, gaps around rim joists, and attics that act like open windows when the temperature drops. Upgrading to modern insulation materials like spray foam or mineral wool solves these problems at the source, cutting energy waste and making your home noticeably more comfortable. We assess each building as a whole rather than just treating symptoms, so the improvements we make actually last.



Drafty rooms, high energy bills, and icy floors do not fix themselves, and patching problems with canned foam from the hardware store only goes so far. Our team at Lamothe Insulation & Contracting takes a different approach. We walk through your property, identify where air is leaking and insulation is failing, and recommend solutions that fit your building and your budget. When you are ready to stop paying to heat the outdoors, give us a call at (508) 847-0119 or email [email protected] to schedule a free consultation.
A homeowner on a rural road just outside Putnam reached out to us about persistent cold drafts and ice damming along the roofline. Our crew inspected the attic and found severely degraded fiberglass insulation that had been installed decades ago, along with major air leakage around the chimney chase and recessed lights. We removed the old material, air-sealed all penetrations, and installed closed-cell spray foam along the roof deck to bring the attic into the conditioned envelope. The homeowner reported that the upstairs stayed consistently warm through the following winter without the need for supplementary space heaters.

Closed-cell spray foam is usually the best choice for older Putnam homes because it air-seals and insulates in one step, which matters a lot when dealing with irregular framing and gaps typical of pre-1970s construction.
Most residential spray foam projects in the Putnam area take one to two days, depending on the square footage and whether insulation removal is needed first.
In many cases, yes, particularly if the existing insulation is damaged, moldy, or has been compressed over time, because installing spray foam over compromised material traps problems in place.
Once spray foam cures, which typically takes 24 hours, it is inert and non-toxic, and our crew takes proper ventilation precautions during the installation process to keep everyone safe.
