the type of insulation we install

Clean and well-maintained insulation helps you regulate your home’s energy, reduces toxins in the air, and keeps moisture out of your attic, crawl space, and walls. 


Blown In attic insulation is a type of insulation that is made of either cellulose, fiberglass, or similar materials that are thick, dense, and lumpy in consistency. Blown-in attic insulation helps to retain warm air inside your home during winter and prevent heat from entering during summer, leading to reduced energy consumption and cost savings.


Batt insulation is a form of insulation that comes in pre-cut, flat pieces, resembling a small blanket, and can be made from a variety of materials including fiberglass and mineral wool. Batt Insulation is an energy-regulating mechanism that can be installed in the framing, ceilings, floors, attics, and walls of your home.


Cellulose insulation is made up of recycled paper products, primarily newspaper. This product is 82-85% recycled material. The manufacturing process reduces the recycled paper products to very small pieces, which are then fiberized and mixed with a flame and insect retardant, usually mineral borate.


Foam board insulation is a lightweight rigid board, usually 4-by-8 feet in dimension. Foam board insulation is often used to insulate areas of a structure that are not suitable for batts or blown-in insulation, such as cement block walls.


Roxul is made of mineral or stone wool. Roxul insulation is used in the walls, ceilings, and attics of homes to reduce the movement of heat, cold, or sound.


Closed-cell spray foam is a type of polyurethane foam insulation that forms an air seal and has a high R-value. When sprayed out of the tip of the spray foam gun, the substance gradually expands, filling in the cracks of your crawl space or attic before curing.

Signs you need new insulation:

physical signs:

You may notice temperature variations from room to room. High energy bills due to heating and cooling being used consistently and icicles hanging from your rooftop. 

drafty home:

If you notice drafts around vents or windows signaling air leakage better insulation will address all of these issues. 


Not only can there be physical damage to your insulation, but you may also have an under-insulated crawl space. The code and regulations for insulation have changed in the past 10 years and it is a good idea to compare your existing insulation type and thickness (R-Value) to the local and U.S. Department of Energy’s recommendations. 


According to studies, approximately 90% of single-family homes in the U.S. are under-insulated, especially the homes built before 1960.


benefits of insulation installation

Properly installed insulation will offer immediate and long-term benefits. Local building energy codes are driving greater energy efficiency. 

reduce energy costs

Properly installing insulation in your home will significantly reduce the need for energy, which leads to cost savings on your heating and cooling costs. It acts as a barrier that prevents heat from escaping during the winter and keeps your house cooler in the summer. 

prevents moisture condensation

Insulation if properly installed will help prevent condensation on surfaces, which can lead to moisture-related issues such as mold growth and structural damage. 

reduces emissions of pollutants

Installing insulation products and air sealing is the first and best step towards decarbonizing our built environment. A study done by a coalition of trade associations including the North American Insulation Manufacturers Association, Contractors Association of America, American Chemistry Council, and Insulation Manufactures Association, found that building operations account for approximately 30% of annual, economy-wide greenhouse gas emissions in the US.

Improved comfort

Insulation does not only lower your energy costs, but it also will enhance your indoor comfort. It reduces heat flow and helps maintain consistent indoor temperatures, making your living space more pleasant. 


comprehensive insulation installation services

At Insulation Co. LLC, we have decades of experience properly identifying, removing, and preventing mold growth in hundreds of homes in Seattle, Kent, and Mt. Vernon Areas. We have a simple and effective mold remediation process to protect you and your home.


Our comprehensive insulation installation services include insulating the water pipes and installing a vapor barrier. Humidity and moisture are common problems in many homes. One of the best ways to keep moisture out of your home is with a vapor barrier. A professionally installed vapor barrier can drastically diminish moisture build-up in your crawl space area. Insulation Co. provides removal and replacement of vapor barriers in your home.


Insulation Co.’s insulation installation requires more than just installing the insulation. While insulation excels as a thermal barrier, it isn’t the best air barrier. To mitigate air leakage, our insulation experts will apply an air foam seal around lights, plumbing, and wires that penetrate the drywall. This reduces energy loss and helps to regulate interior temperatures.

Drill and fill blown-in interior wall insulation installation is a process in which small holes are drilled into the interior walls of your home, and loose-fill insulation is blown into the wall cavity. This method of insulation installation is ideal for existing homes that do not have insulation or have inadequate insulation in the walls. The process begins by drilling small holes into the walls, typically near the ceiling or in the upper portion of the wall. The insulation is then blown into the wall cavity using a special machine, filling the space between the studs with loose-fill insulation. Once the wall cavity is filled, the holes are plugged with a material that matches the wall finish, leaving a seamless, finished look. Drill and fill blown-in interior wall insulation installation can provide several benefits for homeowners, including improved energy efficiency, noise reduction, and increased comfort. It can also help to reduce the amount of dust and allergens that enter your living spaces, improving indoor air quality. If you’re considering drill and fill blown-in interior wall insulation installation for your home, it’s important to work with a professional insulation contractor who has the knowledge and experience to ensure that the job is done right.
