Blown-In Insulation Services in NH, MA, & ME

Keep your heat exactly where you want it with professionally installed blown-in attic insulation.

Cold rooms and a heating system that runs nonstop can point to an under-insulated attic. Blown-in insulation adds loose-fill material to areas where your home needs better coverage, helping slow heat loss and make indoor temperatures easier to manage.

Adam Vaillancourt Roofing & Gutters knows New England attics from the insulation to the roof. We’ll find where yours falls short and provide the insulation it needs for better coverage and comfort.

What Is Blown-In Insulation?

Blown-in insulation is loose-fill material installed with a hose that fills around framing, wiring, and tight attic spaces where pre-cut batts leave gaps.

Our insulation services include both blown-in cellulose and fiberglass. Before recommending an upgrade, we look beyond insulation depth to attic ventilation, air leaks, moisture, and roof-deck conditions.

Cellulose vs. Fiberglass Blown-In Insulation

Cellulose uses recycled paper fibers treated for fire resistance and generally provides a higher R-value per inch. Its loose-fill texture also works well around framing and other irregular attic spaces.

Fiberglass uses fine glass fibers and tends to settle less over time. Which material makes sense depends on the attic and what the project calls for.

What to Expect With Blown-In Insulation Installation

Before we add new insulation, our blown-in insulation contractors check for air leaks or ventilation issues that need attention. Then we’ll install the blown-in insulation to the appropriate depth and check the finished coverage across your attic.

Benefits of Blown-In Insulation

When your attic falls short on insulation, you can feel the effects well beyond the attic itself. Here’s where blown-in insulation can make a difference:

Reduce Heat Loss: Insulation slows heat transfer between your living space and attic. During a New England winter, it helps keep more of the heat you’re paying for inside your home.
Reach Irregular Spaces: Loose-fill material settles around framing, wiring, and other irregularly shaped spaces.

Improve Year-Round Comfort: Better attic insulation helps reduce the temperature swings that leave certain rooms noticeably colder in winter or warmer in summer.
Help Reduce Ice Dam Conditions: Insulation helps limit attic heat loss, while air sealing and ventilation help manage the heat and moisture that can contribute to ice dams.

Blown-In Insulation for Attics and Other Areas

Attics are a common place to add blown-in insulation, but loose-fill material may also work in other areas.

Attic Insulation

Blown-in insulation fills around framing, wiring, and other spots where attic coverage can fall short, while still leaving room for the attic to breathe. We keep eaves and soffit airflow clear as we install insulation so better coverage doesn’t block the ventilation your attic needs.

Existing Wall Cavities

Blown-in insulation can also improve coverage in existing wall cavities, giving homeowners another option for areas that may be difficult to insulate with pre-cut batts. We’ll determine whether blown-in insulation makes sense for the space during the assessment.

Crawl Spaces and Other Areas

During your free assessment, we’ll check crawl spaces and other areas to see whether blown-in insulation is a good fit and recommend the right approach.

Our Blown-In Insulation Process

Step 1 — Free On-Site Assessment

We start by inspecting your existing insulation and attic access. Once we understand your space, we’ll walk you through our recommendation and provide a written quote.

Step 2 — Preparing for Installation

Once you approve the quote, we’ll schedule the installation and handle any prep the attic needs before we install new insulation.

Step 3 — Installation Day

Our team uses specialized equipment to distribute the insulation at the planned depth and coverage. Once installation is complete, we clean the work area and leave it in the condition we found it.

Step 4 — Final Inspection and Follow-Up

We check the finished insulation to make sure it was installed properly. If your project qualifies for an eligible energy-efficiency program, we can also help with the required documentation.

The cost of blown-in insulation depends on your attic and how much work it needs. Size, existing insulation, access, material choice, and the amount of insulation needed can all affect the price. Your free on-site assessment gives us everything we need to price the job accurately.

Blown-In Insulation FAQs

How much does blown-in insulation cost in NH, MA, or ME?

It depends on the attic size, current insulation, access, material, and how much new insulation the space needs. That’s why we inspect the attic before quoting the job.

Can blown-in insulation be added on top of existing insulation?

Often, yes. We first check the condition and amount of insulation already in the attic. If the existing material can stay in place, we’ll determine how much additional insulation the space needs. Wet, damaged, or otherwise problematic insulation may need attention first.

How long does blown-in insulation installation take?

Many insulation projects can be completed in a single day, but larger spaces or projects that also require insulation removal or air sealing may take longer. We’ll let you know what to expect based on the scope of your project.

Will blown-in insulation settle and lose R-value over time?

Some settling can occur, especially with cellulose. Fiberglass loose-fill generally settles less. Proper installation accounts for the material being used so the finished insulation provides the planned coverage and thermal performance.
