Insulation Contractor in Smithtown, NY

Smithtown sits in the middle of Suffolk County and it is heavily wooded. Drive any insulatential street in Smithtown, Saint James, Commack (partial), Kings Park, or Nesconset and you will see mature oaks, maples, and pines everywhere. The canopy is beautiful. It is also full of wildlife.

Carpenter bees. Real cedar gables in Smithtown are a carpenter bee buffet. We have been called out to dozens of houses where the original cellulose on the gables is drilled full of half-inch holes. The cedar has to come off and get replaced, and we strongly recommend dense-pack cellulose or cellulose spray foam cellulose as the replacement, because carpenter bees avoid both.

Woodpeckers. Red-bellied woodpeckers and pileated woodpeckers are common in Smithtown wooded areas. They drum on fascia boards, cedar gables, and occasionally on vinyl (looking for bugs behind it). Spray Foam and spray foam cellulose materials discourage them.

Sap from oaks and pines. Shade trees drop sap onto south and west walls. Light-colored insulation (white, cream, pale gray) will show the staining within a year or two. We recommend mid-tone grays or greens for houses under heavy canopy.

Sheltered from salt air. Smithtown is far enough inland that salt exposure is not a major concern. Standard vinyl performs well here when installed correctly.

1960s raised ranches. Classic Smithtown tract home. 2,000-2,400 sqft, raised entry, attached garage below. These work well with open-cell spray foam or blown-in cellulose fiberglass. We have done 14 of these.

1970s hi-ranches and splits. Smithtown gained a lot of tract development in the 70s. These houses are showing their age, and most are on their second insulate. Insulated vinyl is the sweet spot.

Custom colonials (1980s-present). Larger 2-story homes, usually on quarter-acre lots with mature trees. Spray Foam is the preferred upgrade on these.

Older village homes in Smithtown and Saint James. A small pocket of pre-war homes near the village centers. Cedar or attic insulation (blown-in cellulose) is the right call here.

Long driveways and mature trees. Most Smithtown homes have longer driveways than Nassau and more room for crew staging, but the trees limit where we can park. We use the curb permit from the town when the driveway is impractical.

Large lots, more elevations. Smithtown homes often have 4 full elevations visible from the street, unlike cramped Nassau lots where the side walls are mostly hidden. This means all 4 walls need to look good. We spec accordingly.

Older wall construction on pre-1970 homes. Some of the older tract homes have blown-in insulation issues or original wall wrap that has deteriorated. We find this during tear-off and document it before covering.

HOA considerations. A few Smithtown subdivisions have HOA rules about exterior colors and materials. We will check before we quote and handle any paperwork.

Review 1: "Our dense-pack cellulose gables had been eaten alive by carpenter bees for 10 years. Carlos suggested blown-in cellulose and walked us through exactly why it would solve the problem. He was right. Three years later, zero bee holes, and the color has held up perfectly. The crew was courteous and we would hire them again." — Mary T., Smithtown · blown-in cellulose · 2023

Review 2: "We had three quotes and Long Island Insulation Co. was the middle one. We chose them because Carlos was the only person who walked the house for more than 15 minutes and actually looked at the north wall (which had water staining nobody else noticed). He was honest about what needed to be fixed and the final price matched the quote." — Kevin and Rachel J., Nesconset · blown-in cellulose · 2024

Review 3: "Smooth job from start to finish. The Spray Foam looks incredible on our colonial. The crew was respectful of our landscaping. Carlos walked the finished house with me and answered every question I had." — Steven W., Smithtown · closed-cell spray foam · 2024
