4 Mistakes Good Window Installation Pros Don’t Make

Window replacement is not just about investing in the right set of replacement windows units; it is also about choosing the right contractor that can do the job properly. To ensure the whole installation process is done the right way, work only with a trusted local contractor like Timberland Exteriors. As a reliable window and new roof installation experts, we know better than to make these common mistakes:

1. Leaving Smudges and Stains on Newly-Installed Windows

Window installers like us know that windows are a vital design element of every home. As such, we see to it that we handle the replacement units with care, from the time we deliver them to your home until we fully install them. We make sure not to leave foam and sealant smears on the window surfaces, including the glass and frames.

2. Wrong Size of Rough Opening

Requirements for a residential window’s rough opening will often depend on the window style and local building codes. Our window installation service experts begin work by first taking precise measurements for the replacement window unit to fit the opening, with enough space for the sealant and spray foam to be applied.

3. Misapplying the Spray Foam

Expanding spray foam is applied to spaces between the window frames and the opening to ensure better insulating value for the replacement windows. Inexperienced installers, however, can easily make mistakes while using this tool—apart from filling the entire window perimeter, they may also dispense the foam too much, causing frames to distort and warp.

4. Failure to Adhere to Installation Standards

Various installation methods apply for most windows, but there could be special requirements that installers need to adhere to depending on the manufacturer. Our experienced installers always make sure to follow manufacturer instructions for the replacement window units’ excellent, long-lasting performance.

When it comes to roof maintenance, most homeowners focus on shingles, flashing, or gutters. But two of the most critical—yet often overlooked—components are the soffit and fascia. These structural elements play a silent but vital role in maintaining your roof’s integrity, ventilation, and overall curb appeal.
