Weatherization Essentials - Caulking & Weatherstripping

Many homeowners immediately think of attic insulation and window replacement when it comes to energy efficiency improvements. But one of the most cost effective and impactful solutions is good ole fashioned caulking and weatherstripping. Many times window replacement isn't even necessary, the windows and exterior doors are simply in need of caulking and weatherstripping to provide an effective seal.

Many homes, new and old, are inadequately caulked at the exterior and interior which will undoubtedly result in air infiltration, higher energy bills, and a less comfortable living space. St. Louis, with its hot, humid summers, is the last place you want to live without properly sealed windows and doors.

The caulking process involves installing a bead of flexible caulk to the joint where different materials (wood/brick/siding/drywall/etc.) meet. There are different types of caulks for different applications, and you really need an experienced contractor to steer you in the right direction. Installing the wrong kind of caulk can leave you with a failing seal within a year or sooner. Some homes also require caulking at the interior, where door and window trim meets drywall, as this step is sometimes skipped by builders. This is a critical part of the caulking process, and necessary to keep drafts from getting into your home. In addition to windows and doors, a thorough energy efficiency contractor (such as Green Space Construction) is also careful to caulk at electrical and gas service entrances, dryer exhaust vents, cable and phone lines, water faucets, air conditioners, and other vents.

Weatherstripping provides the same thermal benefits as caulking, by sealing the seams between operable doors and windows and the interior of the jamb/casing. Properly installed weatherstripping will allow the window or door to seal tightly when closed, but will allow it to open and close freely. Weatherstripping is available in foam, rubber, vinyl, and metal materials. Each of these materials has a place, and we recommend the right materials for your home's needs. After a number of years, old weatherstripping can become worn and ineffective, requiring replacement. Green Space Construction will assess your home's conditions and make the right recommendations to balance cost with potential savings, insuring that your home is comfortable and efficient.
