Select New Efficient Replacement Windows
7. Ensure proper installation
A window can only perform well if properly installed. Quality installation is critical for an airtight fit and a continuous water barrier to prevent drafts, water damage and condensation. The complexity of the installation depends on whether you are considering complete window replacement or inserting windows or sash kits within the existing frame. Make sure to follow manufacturers' recommendations on whether the particular installation requires trained professionals or whether do-it-yourself is an option.
Finding quality installers
The first place to inquire about quality installers is the manufacturer from whom you are purchasing the windows. Each manufacturer has detailed installation requirements and specifications for their products and may have recommendations of in-house installers and programs, 3rd party installers, or installation certification programs.
There are standards for proper window installation, and installers are well advised to follow these along with the manufacturer's installation requirements. The most prominent of these standards is ASTM Standard E 2112. Installers who are certified through nationally recognized certification programs or through the training programs offered by manufacturers are likely to be familiar with this standard.
Window manufacturers may have certification programs for installers of their own products. Installers may also be certified by nationwide programs such as:
- InstallationMasters™. The website includes a directory of certified installers in the United States.
- WindowWise National Certification Program. The website includes a directory of certified installers in Canada.
Ultimately, finding trusted installers is a case-by-case decision. References may help with recommendations.
