Cromwell’s Insulation Pros — Real Results

You may need more insulation if your home feels drafty, rooms have uneven temperatures, or energy bills are high. Visible attic joists, cold floors, and constantly running HVAC systems are key signs. Nealon Insulation offers free assessments to identify and fix under-insulated areas.

The most important areas to insulate in a Connecticut home are the attic, exterior walls, basement or crawl space, and rim joists. These zones prevent heat loss, control moisture, and reduce energy bills. Nealon Insulation customizes solutions to target the biggest energy leaks for maximum comfort.

Most insulation jobs are completed in one day, depending on home size and insulation type. Attics take a few hours, while walls or crawl spaces may take longer if air sealing or removal is needed. Nealon Insulation provides a clear schedule and finishes with minimal disruption.

R-Value measures how well insulation resists heat flow. Higher R-values mean better insulation performance—keeping heat in during winter and out in summer. It’s essential for energy efficiency, especially in Connecticut’s climate. Different areas of your home require different R-values based on code and comfort needs.

In Connecticut, R-49 to R-60 is recommended for attics, R-13 to R-21 for walls, and R-19 to R-30 for floors or crawl spaces. These values follow Department of Energy guidelines for Zones 5 and 6. Nealon Insulation helps meet or exceed these standards for comfort and code compliance.

Nealon Insulation uses cellulose, fiberglass, and spray foam to match different homes and budgets. Each product is selected for goals like energy efficiency, soundproofing, or eco-friendliness. With nearly 50 years of experience, Nealon recommends the best solution for long-term comfort and savings.

Yes, we would first ask when your house is built as that is a determining factor. Building codes started in 1971 in Connecticut so anything prior most times is empty unless renovated, but in between years may so we can provide you with a wall test. This is where we would remove a couple rows of siding or pieces of clapboard, drill a 2 1/8” hole to see what is inside and replace the siding. We can add here, we usually charge $150 for a wall test, which we would credit to the job if they were in need of insulation and went with us. You can also choose to get an energy audit to have a blow-door test to find out your insulation needs.
