Sealing and insulating the "envelope" or "shell" of your home — its outer walls, ceiling, windows, doors, and floors — is often the most cost-effective way to improve energy efficiency and comfort. ENERGY STAR estimates that a knowledgeable homeowner or skilled contractor can save up to 20% on heating and cooling costs (or up to 10% on their total annual energy bill) by sealing and insulating. Weatherization Services LLC, a Milwaukee Insulation Contractor, will use the right tools and knowledge to locate these leaks and seal them up properly.
Many air leaks and drafts are easy to find because they are easy to feel — like those around windows and doors. But holes hidden in attics, basements, and crawlspaces are usually bigger problems. Sealing these leaks with caulk, spray foam, or weather stripping will have a great impact on improving your comfort and reducing utility bills.
Homeowners are often concerned about sealing their house too tightly; however, this is very unlikely in older homes. A certain amount of fresh air is needed for good indoor air quality, and there are specifications that set the minimum amount of fresh air needed for a house. If you are concerned about how tight your home is, hire a contractor, such as Weatherization Services LLC, a Milwaukee Insulation Contractor, who can use diagnostic tools to measure your home's actual leakage. If your home is too tight, a fresh air ventilation system may be recommended.
After your home sealing project, Weatherization Services LLC, a Milwaukee Insulation Contractor, will check to make sure that your combustion appliances (gas- or oil-fired furnace, water heater, and dryer) are venting properly.
