Services
Spray Foam Insulation
Our spray foam insulation creates an airtight seal in walls and attics, significantly improving energy efficiency while reducing noise transmission. This advanced solution expands to fill gaps, preventing air leaks and moisture infiltration that cause energy loss. Homeowners benefit from lower utility bills and enhanced indoor comfort year-round through our professional installation of high-performance closed-cell and open-cell foam systems.
Blown-In Insulation
We install cellulose and fiberglass blown-in insulation using specialized equipment to achieve uniform coverage in hard-to-reach spaces. This method works exceptionally well for existing walls and attic floors, providing excellent thermal performance without major structural disruption. Our technicians ensure proper density and R-value compliance to maximize energy savings while maintaining building code requirements.
Blanket Insulation
Our pre-cut fiberglass and mineral wool batt insulation offers a cost-effective solution for standard wall cavities and accessible attic spaces. We ensure proper installation with attention to compression and coverage gaps, maintaining optimal thermal resistance. This traditional method remains popular for new construction and simple retrofit projects requiring reliable performance.
Aluminum Gutters
We fabricate and install custom seamless aluminum gutters on-site to precise specifications, eliminating leaks at joints. Available in 5-inch and 6-inch sizes with .032-inch thickness, our systems feature baked-enamel finishes for lasting durability. Optional Leaf Relief protection prevents debris accumulation while maintaining aesthetic appeal for residential properties.
Copper Gutters
Our copper gutter systems combine functional water management with architectural elegance. Available in K-Style and half-round profiles from 5-inch to 8-inch commercial-grade sizes, these 16oz copper installations develop natural patina over time. We offer both seamless fabrication and traditional panel assembly methods for historic or high-end modern properties requiring premium drainage solutions.

Report
Just got off the phone with Ted who manages the foam insulation business for a quote on an attic insulation project. I was hoping to insulate from my soffit up to the ridge vent and bring the HVAC equipment inside the thermal envelop while building out the attic. Ted was suggesting open-cell foam at R-38 when I was considering closed-cell foam at R-49. When I tried to discuss the pros and cons and understand the recommendation better, Ted told me that he's been doing this for years, and he doesn't have the time to explain this to me due to his busy schedule. He suggested I go find someone else

I called Eric Flemming at Custom Insulation in a panic because I needed to have my attic insulated in order to pass city inspection and move into the house I'd spent months renovating. He called me back right away, came down for an estimate within an hour, gave me the estimate shortly after that and had a team at my house the next morning with an exact window of when they'd be there (the team was equally awesome - super friendly and informative). That combination of responsiveness, professionalism and accountability is so hard to come by these days. 10/10 would recommend.

This company was very tough to work with. They were scheduled to do the work while i was on vacation so I could be there while they were inuslating a crawl space and last minute their sales guy said "no i had you down for next week"! So i took off more time from work the following week. They showed up on the rescheduled day, started the work then told me they couldn't do the work for wht they agreed on! Salesman John called me and said his price was only for a portion of what i had showed him originally. Total BS. They were at my house dressed and ready to go and they didn't even try to negotiate

Report
I went through the Mass Save Energy audit and another contractor 3 years ago. That contractor arrived on the appointed day and was one man short and one man wreaked of alcohol. They couldn't start the job and I was relieved. I went to Custom Insulation this time and couldn't have been happier. Angel and his crew were on time, clean and tried their best not to disrupt our lives over the two days. These companies can be VERY unreliable so finding a good contractor was a relief. I highly recommend them.
