Floor Insulation

Warm Up Your Floors with Insulation Near Wilmington, Dover, Bear

Spray Foam in the crawl space in Dover

Many homes lack the necessary insulation to keep their floors and home comfortable. Our spray foam insulation in all the cavities beneath the home create a temperature barrier between the outside air and the inside of the home.

Ground level floors may get too cold in the winter if the spaces beneath them are cold. Existing insulation (if there is any) is often inadequate or improperly installed beneath the floor boards. Floor surfaces cool as the heat they contain is literally sucked away. Drafts cool floors, too.

As heated air escapes from the upper levels of your home, cold air is drawn in through cracks around lower level windows and doors, from below the floor, and from outdoors. The cold air is heavier than warm air, so it tends to hug the floor and cool its surface.

Insulating the floors in your home will reduce drafts and help you save each year on energy costs!

    Spray Foaming Rim Joists in Queenstown, MD


    A rim joist is a board that caps off the floor joist and forms the outer box of the floor assembly. Without the proper insulation or air sealing of the rim joist could result in condensation and higher fuel and electric bills. More than 30% of air 

    This is what one homeowner in Queenstown, MD were experiencing. Living with cold floors and a increase in cost of home ownership, they went online and found Dr. Energy Saver. 

    Our In Home Comfort Specialist then came out and inspected their crawl space and noticed that not only were the rim joist not insulated, but had noticed microbial growth had started forming. The rim joist were sweating from the hot/humid temperatures inside the crawl space causing this growth.

    Immediately, the homeowners were very concerned about the microbial growth and also their cold floors and scheduled the project. Our production team then came in and spray foamed each rim joist. This reduces heat loss and infiltration of cold air by sealing and insulating the joist and also getting rid of the microbial growth!

Finding the Best Solution

Garage Insulation in Grasonville

Floors over garages are almost always cold but with our dense-pack cellulose insulation, that’s a thing of the past.

When possible, convert the space below your floor to a conditioned (warm) space. For example, by insulating basement or crawlspace walls with the proper insulating material, those spaces will become much warmer and so will the floors above them. See basement insulation and crawlspace insulation for more information.

When it’s not possible to insulate the walls of your basement or crawlspace, ask us about insulating the joist bays (spaces between joists) under the floor. We have various types of insulation materials that can do the job, including spray foam and rigid foam.

Our installers will pay special attention to critical areas, such as perimeter rim joists – a notorious source of air leakage.

Whichever option you choose, it should be accompanied by a thorough air-sealing of your home. Air sealing reduces the stack effect that is continually trying to expel air through small openings all throughout the upper reaches of your home, while it pulls in air through gaps around the lower levels of your home. See air sealing for more information about this Dr. Energy Saver service.

Cold floors above garages, balconies, and porches

More tips for warmer toes

  • Vinyl, carpet, cork, and wood feel warmer than ceramic tile, stone, and concrete.
  • Install glass doors on your fireplace.
  • Where feasible, supply outdoor combustion air to your furnace or boiler. Drawing combustion air from your basement or utility closet creates drafts.
  • Weatherstrip your windows and doors, especially the gaps between the bottom of exterior doors and the thresholds.
  • Wear warm slipper and socks!

Ground level floors aren’t the only ones that can get cold. Rooms built above garages are notorious for having cold floors due to lack of insulation and so is any floor that’s cantilevered (overhangs the foundation perimeter).

balconies, bow and bay windows, and bump-outs are all examples of cantilevered spaces. Their floors are especially prone to air leaks because of ill-fitting soffits (boards used to seal under the overhang) combined with direct exposure to wind. Dr. Energy Saver has detailed solutions for each and every situation.

We will specify the most appropriate insulation solution based upon you home’s construction and your budget.
