Irondequoit's 1920s through 1950s colonials and capes sit between the bay and Lake Ontario, where the wind off the water finds every gap and lake-effect snow piles up for months. Your home was built with plaster walls over balloon framing, a basement of Medina sandstone or concrete block, and an attic that bakes in July and freezes solid in January, collecting condensation and ice dams every winter.
Homeowners in Irondequoit (14617) call Rochester Spray Foam Insulation because the original flat attic fill settles, the rim joists leak cold air, and the knee-wall bedrooms upstairs stay 15 degrees colder than the rest of the house. We have been sealing and insulating homes in Irondequoit and across Rochester since 2012, and we know exactly what your house needs to stop the draft, the moisture, and the heating bill.
Spray Foam Insulation in Irondequoit (14617)
Irondequoit's building stock was framed for a different climate. The colonials and capes that line your neighborhoods were built before air sealing and modern insulation existed, and the attics and crawl spaces were never designed to handle the humidity swings and temperature extremes that Lake Ontario throws at us every season. Summer humidity drives moisture into the attic from below; winter cold and lake-effect snow load the roof with ice dams that back water into the soffit and fascia. The original blown-in fill has settled to half its R-value, and the rim joists and band joists around your basement rim are wide open to the outside air.
Spray foam insulation solves this in a way blown-in never can. Closed-cell foam in the attic creates an air barrier and a vapor retarder in one pass, stops the ice dams at the roof deck, and lets the attic stay cold and dry all winter. Open-cell foam in the rim joists and band joists seals the thermal bypass that makes your basement cold and your heating bill jump in November. Wall injection foam reaches into the cavities of your 1920s walls without tearing them open. We remove the old, contaminated, or settled insulation first, then install the right foam at the right thickness and R-value for your Irondequoit address, with a written estimate that names both.
Our team has been fully insured and working in Irondequoit and across the Rochester area for over a decade. We know the building code that applies to your neighborhood, the moisture patterns that come off Lake Ontario, and how to build an assembly that handles both seasons without fail.

How a Job Works in Irondequoit
We start with a free on-site assessment. You show us the attic, the crawl space, the rim joists, or the wall cavities that need work, and we walk through the space with you, naming what we see, what has to come out, what stays, and what the finished job will look like. We take measurements, photograph the existing insulation and any moisture or settling, and leave you with a written estimate that specifies the R-value and thickness we will install, the foam type (open or closed cell), and the price. No surprises, no change orders unless you ask us to change the scope.
On the day of the work, we set up mechanical ventilation in the space and spray the foam in controlled passes, holding the manufacturer ratio and drum temperature steady so the foam cures properly. If the attic or crawl space is occupied or connected to living space, we manage the re-entry window (typically 24 to 48 hours), and we coordinate around your HVAC, any roofing work, or other trades on the job. If old insulation has to come out first, we remove it completely and haul it away, leaving the substrate clean and dry before any foam goes down. We will not spray over wet, contaminated, or actively leaking areas; we fix the moisture first or we walk away.
When the foam has cured, we do a final walkthrough with you, confirm that the thickness and coverage match the estimate, and leave the property clean. Your attic or crawl space is sealed, insulated, and ready to perform.
Attic spray foam insulation in Irondequoit typically runs from $1.50 per square foot for open-cell foam to $1.20 per board foot for closed-cell, depending on the depth and R-value your attic needs and whether old insulation has to be removed first. A typical 1,200-square-foot Irondequoit attic with 4 to 6 inches of closed-cell foam and removal of the original settled fill costs between $3,500 and $5,500. Wall injection foam for a closed cavity runs from $2 per square foot. Rim joist and band joist sealing starts at $650 for a small basement rim; crawl spaces start at $2,500 depending on the area and the depth of foam. Insulation removal alone starts at $950. The final price depends on the square footage, the foam type and thickness you choose, what has to be removed, and how easy the access is.
