Upgrading your attic with blown-in insulation is one of the smartest moves you can make to improve your home’s energy efficiency, comfort, and even resale value. But before the insulation goes in, a little preparation goes a long way. At Custom Insulation Company, Inc., we want homeowners to get the most out of their investment—starting with a properly prepared attic.
First things first: if your attic is used for storage, it’s time to clear it out. Blown-in insulation needs to be evenly distributed across the entire attic floor. Boxes, bins, or stored furniture will block coverage and reduce the insulation’s effectiveness. Remove all items before the installation team arrives, and consider finding a new storage solution if you plan to maximize your attic’s energy-saving potential.
Before any insulation is added, it’s crucial to seal up gaps, cracks, or openings around wiring, plumbing, or framing. These small leaks may seem minor, but they can lead to significant heat loss in winter and increased cooling costs in summer. Our team will typically perform a quick inspection and recommend sealing measures if needed, often using spray foam or caulking in key areas.
Moisture and insulation do not mix. If your attic shows signs of leaks, condensation, or mold, those problems should be addressed before insulation is installed. Trapped moisture can reduce insulation performance and lead to long-term damage. If you're not sure what to look for, we can help identify potential issues during our initial assessment.
Proper attic ventilation helps regulate temperature and prevent moisture buildup. Before installing blown-in insulation, make sure that soffit vents, ridge vents, or gable vents are unobstructed. This keeps air circulating, which improves indoor air quality and helps your insulation work more efficiently.
To keep insulation from blocking airflow, we often install baffles (also called rafter vents) near the eaves. These guide air from soffit vents into the attic. In some homes, insulation dams or barriers may also be added around light fixtures, chimneys, or access hatches to ensure safety and compliance with building codes.
Every home is different, and a professional eye can spot issues you might miss. At Custom Insulation Company, Inc., we offer thorough attic evaluations and will walk you through every step before installation. We’ll ensure your attic is prepped, safe, and ready for a successful blown-in insulation upgrade.

Whether you're building a new home or upgrading an older one, proper insulation is one of the smartest investments you can make. Blanket insulation—commonly available in batts or rolls—is a popular choice for its affordability, ease of installation, and reliable performance. But how and when it's installed can vary significantly depending on whether you're working with new construction or completing a retrofit. Let’s break down the key differences.
In new construction, the process is typically more straightforward. Since the walls, ceilings, and floors are open and accessible before drywall is installed, our team can fit insulation seamlessly into place with minimal disruption. This allows us to ensure complete coverage, precise cuts, and optimal R-value performance. It's faster, cleaner, and highly cost-effective during the early stages of a build. If you're planning a custom home or commercial project, installing blanket insulation early ensures long-term energy efficiency and comfort from day one.
Retrofits, on the other hand, require a more customized approach. In existing buildings, we're working around finished walls, existing utilities, and sometimes outdated or improperly installed insulation. Access can be limited, and extra care must be taken to minimize disruption while improving thermal performance. Despite the added complexity, retrofitting with blanket insulation is still a strong option—especially in attics, crawlspaces, and unfinished basements where access is easier and the energy savings can be significant.
At Custom Insulation Company, Inc., we bring decades of experience to both types of projects. Whether you’re breaking ground or breathing new life into an older property, our team ensures the job is done right—with attention to detail, performance, and long-term value.
Not sure which approach is best for your project? We’re happy to help. Contact us today for a free consultation and let’s talk about how blanket insulation can work for you.

When the summer sun is beating down and your AC is working overtime, you might be wondering:
The answer could be right above your head—literally. If your attic or walls aren’t properly insulated, that summer heat is sneaking into your home and making your cooling system work twice as hard.
That’s where blown-in insulation comes in.
Blown-in insulation is a loose-fill material (usually fiberglass or cellulose) that’s sprayed into hard-to-reach areas like attics, wall cavities, and crawlspaces. It fills every gap and crevice—giving you a more complete thermal barrier than traditional batts or rolls.
Here’s how blown-in insulation helps keep your home cooler when temperatures rise:
Reduces Heat Transfer: It acts like a shield between your attic and living spaces, preventing heat from radiating downward.
Protects Your AC System: With less heat entering the home, your air conditioner doesn’t have to run as often—saving you money and reducing wear and tear.
Seals the Gaps: Blown-in insulation fills tiny cracks and corners that other insulation can miss, stopping hot air from sneaking in.
Maintains Even Temps: Say goodbye to hot spots and uneven cooling. Blown-in insulation helps your entire home stay consistently comfortable.
The best part? Proper insulation can reduce your cooling costs by up to 20–30%. Over time, it pays for itself through lower energy bills and a more comfortable home all summer long.
Let Custom Insulation Company, Inc. help you take control of your indoor comfort. Our blown-in insulation services are fast, affordable, and tailored to your home’s needs.

When your home feels drafty in the winter, too hot in the summer, or your energy bills seem to keep climbing, insulation could be the culprit. Specifically, batt insulation—also known as blanket insulation—might not be doing its job as well as it should.
At Custom Insulation Company, Inc., we’ve helped homeowners throughout Massachusetts identify and solve insulation issues for decades. Here’s how to tell if your home needs more batt insulation—and what you can do about it.
If you’ve noticed your heating and cooling bills rising even when usage stays the same, your insulation could be underperforming. Blanket insulation may have settled, shifted, or deteriorated over time—especially in older homes.
What to do: A home energy audit can pinpoint which areas are leaking energy and whether additional insulation is needed.
Do some rooms in your house stay chilly while others are warm? That’s a classic sign of inconsistent insulation coverage. Insufficient batt insulation in walls or ceilings can cause hot and cold spots throughout your home.
Pro tip: Pay attention to bonus rooms, finished attics, or rooms over garages—these often get overlooked during original insulation.
If you feel cold air creeping in around baseboards or floors feel icy in the winter, there’s a good chance the insulation in your walls or crawl space isn’t up to par.
Batt insulation is often used in exterior walls and between floor joists, but gaps or compressed batts can reduce its effectiveness significantly.
Batt insulation made of fiberglass or mineral wool can last for decades, but over time it can become compressed, damp, or even moldy—especially in basements or crawl spaces.
Signs of aging insulation:
If your furnace or AC never seems to shut off, your home may be leaking heated or cooled air. Inadequate batt insulation in the attic or walls can cause your system to work overtime.
Solution: Adding new batt insulation—or supplementing it with spray foam for tighter air sealing—can reduce system strain and lower utility bills.
If you’ve recently finished an attic, added a room, or remodeled a basement, don’t forget about insulation. These areas often lack adequate batt insulation, especially if they were previously unconditioned spaces.
Don't skip insulation: It’s much easier and cheaper to add it during renovation than to retrofit later.
The best first step is to schedule a free insulation assessment with the experts at Custom Insulation Company, Inc. We’ll evaluate your current insulation, identify gaps, and recommend the best solutions—whether that’s adding new batt insulation, replacing old materials, or combining with spray foam for extra efficiency.

Summer in New England brings sunshine, backyard BBQs — and soaring energy bills. If your home feels like an oven on hot days, the problem might not be your AC unit... it could be your insulation.
At Custom Insulation Company, Inc., we help homeowners across Massachusetts keep their homes cooler and more efficient with blown-in insulation — a smart, cost-effective way to reduce heat gain and cut cooling costs all summer long. Why Attic Insulation Matters in Summer
Heat rises, but in summer, it also comes down from your roof. When your attic isn't properly insulated, it acts like a giant heat trap — baking your living space below and forcing your air conditioner to work overtime.
Blown-in insulation creates a dense, seamless thermal barrier in your attic and walls, helping to:
With better insulation, your AC doesn’t have to run as long or as often to maintain a comfortable temperature. That translates into:
According to the U.S. Department of Energy, proper insulation can reduce heating and cooling costs by up to 20% — and blown-in insulation is one of the most efficient options available.
Whether you're building new, upgrading an older home, or just tired of sky-high cooling bills, Custom Insulation Company, Inc. can help you beat the heat with professional blown-in insulation services.

Proper insulation is key to maintaining a comfortable, energy-efficient home. Blanket insulation—whether it’s fiberglass, mineral wool, or cotton—helps regulate indoor temperatures and reduce your energy bills. However, like any other part of your home, it requires regular maintenance to continue performing at its best.
At Custom Insulation Company, Inc., we believe in not only installing high-quality insulation but also ensuring that it stays in optimal condition. Here are some simple maintenance tips to help keep your blanket insulation working efficiently and effectively for years to come.
Just like other areas of your home, insulation requires occasional check-ups. Make it a habit to inspect your insulation—especially in places like attics, basements, and crawl spaces—at least once a year.
If you spot any issues, call an insulation professional to repair or replace the affected insulation. At Custom Insulation Company, Inc., we offer expert assessments and quick fixes to keep your insulation in top shape.
Rodents and insects love to make nests in insulation, which can significantly reduce its effectiveness. To prevent pest problems:
If you suspect pests have gotten into your insulation, it’s crucial to address the issue quickly to avoid further damage. Our team can help you with pest-resistant insulation options and repair services.
Moisture is one of the biggest threats to blanket insulation. It not only reduces the insulation’s performance but also encourages mold and mildew growth, which can affect indoor air quality.
If your insulation becomes wet, it’s often best to replace the affected areas rather than trying to dry them out. At Custom Insulation Company, Inc., we can help assess water damage and recommend appropriate solutions.
Good airflow is essential for maintaining the effectiveness of your insulation. Without proper ventilation, moisture can get trapped, leading to mold growth and reduced insulation efficiency.
Proper ventilation not only keeps your insulation dry but also contributes to overall home comfort and energy efficiency.
While blanket insulation works to keep your home comfortable, it’s important to be mindful of extreme temperature changes. Sudden temperature shifts can cause the insulation material to expand and contract, potentially leading to gaps and uneven coverage.
Maintain a consistent indoor temperature to prevent unnecessary stress on your insulation.
If you notice any areas where the insulation appears uneven or compromised, it’s a good idea to have them checked by a professional.
While blanket insulation doesn’t require regular cleaning, keeping it free of dirt and dust can help ensure it continues to perform well. Use a gentle vacuum or air blower to remove any debris that may have collected on top of or near the insulation.
Be cautious when cleaning insulation to avoid disturbing the material or causing any damage.
Even with regular maintenance, some insulation may need to be replaced or upgraded over time. If your home is older, or if your insulation has been in place for many years, it may be time to assess its efficiency.
At Custom Insulation Company, Inc., our experts can evaluate your insulation and recommend the best options for keeping your home as energy-efficient as possible.
By following these simple maintenance tips, you can ensure your blanket insulation continues to work effectively, keeping your home energy-efficient, comfortable, and safe for years to come. Regular inspections, proper ventilation, and prompt repairs are key to maintaining the performance of your insulation.

Looking for a smart, sustainable way to make your home or building more energy-efficient? Blanket insulation—commonly installed as fiberglass or mineral wool batts and rolls—is one of the most effective and affordable ways to reduce your carbon footprint while saving money on energy bills.
Here’s how it works:
By keeping warm air in during the winter and hot air out in the summer, blanket or batt insulation significantly lowers the amount of energy your HVAC system needs to maintain a comfortable temperature.
Less energy use means fewer fossil fuels burned at power plants—which directly reduces the carbon dioxide and other greenhouse gases released into the atmosphere.
Once installed, blanket insulation continues working for decades with little to no maintenance. It’s a one-time upgrade that offers continuous environmental benefits.
Choosing high-quality, sustainably sourced insulation materials can help homes and commercial buildings meet LEED and Energy Star standards—boosting both property value and eco-credibility.
Whether you're upgrading your attic, insulating new construction, or simply trying to make greener choices, blanket insulation is a smart step toward a more sustainable future.

At Custom Insulation Company, Inc., we know that comfort in your home goes beyond just temperature control. One of the often-overlooked benefits of blown-in insulation is its ability to reduce unwanted noise, creating a quieter, more peaceful living environment. Here’s how blown-in insulation can help with noise reduction:
Blown-in insulation is made from materials like cellulose or fiberglass, which have excellent sound-absorbing properties. These materials can help to dampen sound by absorbing vibrations that travel through walls, floors, and ceilings, making your home much quieter.
If you have noisy neighbors, children running around, or just want to keep things peaceful in your home, blown-in insulation can significantly reduce the transfer of sound between rooms. It helps to block noise from travel, providing better privacy and a more serene atmosphere in your living spaces.
For those who work from home or have bedrooms near busy areas, blown-in insulation can help create a better work environment by minimizing distractions. It’s also great for making sure you get the quiet rest you deserve, reducing the sound from outside or other parts of the house.
In multi-story homes, sound often travels between floors, creating disturbances. Blown-in insulation effectively minimizes this by filling gaps and providing a barrier that prevents sound from easily traveling up or down between levels.
Not only does blown-in insulation help with soundproofing, but it also improves the overall energy efficiency of your home. By reducing drafts and temperature fluctuations, you get a double benefit—lower energy bills and a quieter, more comfortable space.
At Custom Insulation Company, Inc., we specialize in blown-in insulation that improves both the comfort and acoustics of your home. Whether you’re looking to block out noisy neighbors or create a quieter living environment, blown-in insulation can make a big difference.
Let us help you improve your home’s soundproofing with expert installation of blown-in insulation. Contact Custom Insulation Company, Inc. today for a consultation and learn how we can help you reduce noise and enhance your living space!
