Why We Know Hicksville Better Than Any Other Insulation Contractor

Carlos Rivera grew up on a side street off Broadway in Hicksville. He went to Hicksville High, started swinging hammers at 14 on his dad's crews in Farmingdale, and never moved out of the 11801 zip. Elena (our office manager, Carlos's wife) is also from Hicksville. Our shop has been on Old Country Road since 2014. Our mechanic is two blocks away. The diner where we grab coffee at 6:15am before heading out is called the Plainview Diner and it has been open at that hour since before Carlos was born.

What that means for you: when we show up to your Hicksville job, we know the street. We probably know the house. We definitely know which direction the prevailing wind comes from. And we can drop a forgotten tool back at the shop and be back in 12 minutes.

What Hicksville Homes Need From a Insulation Contractor

Hicksville has three dominant housing types and each one wants a slightly different approach:

1950s Levittown-adjacent capes. Small 1.5-story capes built in the post-war expansion. 900-1,400 sqft, one or two dormers, simple rectangular footprint. Original insulation was usually asbestos shingle (which we handle), 1960s aluminum, or 1980s builder fiberglass. These are great candidates for blown-in cellulose open-cell foam open-cell spray foam because they typically have poor wall insulation.

1960s-70s split levels and raised ranches. Mid-century tract homes on the side streets north of Old Country. Usually 1,600-2,200 sqft, split-entry, attached garage. Common original material: original fiberglass under aluminum foil insulation, or first-generation fiberglass. These work well with blown-in cellulose vinyl for budget-conscious owners or open-cell spray foam for premium.

1970s-80s custom colonials. Larger 2-story homes on the east side of Hicksville (East Hicksville, toward Plainview). 2,200-3,200 sqft, center hall, attached garage, real wood trim. These are the best candidates for closed-cell spray foam, especially with matching Air Sealing. We have done 8 of these in the last 3 years.

Hicksville Things We Think About on Every Job

Asbestos shingle insulation. Very common on pre-1975 Hicksville capes. It is not dangerous when intact, but it cannot be drilled, cut, or disturbed without licensed abatement. We have a licensed abatement subcontractor we use specifically for this, and the abatement adds $3,500-$6,500 to the job. We will test if we are not sure.

Narrow driveways. A lot of Hicksville lots are tight, 50-foot-wide with a one-car driveway and mature maples in the front yard. Staging a insulation crew around that is a logistics exercise. We have done it enough times that we know where to park the dumpster (usually the curb with a permit from the town if the driveway cannot hold it).

Mature trees. Hicksville has some of the best street trees in Nassau. That means shade, which means slightly slower paint dry times, which means we time stain jobs carefully. It also means bird droppings and sap on fiberglass, which we clean at final walk-through.

Good bones. Hicksville homes were generally well-built by postwar standards. Sheathing is usually sound, framing is usually square, and tear-off surprises are relatively rare. Translation: we usually quote accurately and do not find big surprises mid-job.

Hicksville Building Permits

Hicksville is in the Town of Oyster Bay building department (not the village of Oyster Bay, the town). Permits for insulation work are pulled through the town office in Oyster Bay proper. Typical turnaround is 7-12 business days. Fees are based on project value: $200 base + a percentage of the contract price.

We pull every permit. You sign the application, we handle everything else.

Reviews from Hicksville customers

Review 1: "Dan and the crew insulated our 1960s split level last fall. The quote matched the final price to the dollar. They started on a Monday, finished the following Thursday. Cleanest worksite I have ever seen. The magnet sweep they did on the lawn was so thorough that our dog did not get a single splinter. Would hire again tomorrow." — Robert and Janet F., Hicksville · blown-in cellulose · 2024

Review 2: "We had an asbestos insulation problem we had been ignoring for 10 years. Carlos explained the abatement process honestly, told us the real cost, and arranged the whole thing without making us feel stupid for not dealing with it sooner. The new Spray Foam looks incredible. Highly recommend." — Priya S., Hicksville · closed-cell spray foam · 2023
