Transforming Two Windows into a Patio Door for Better Light & Access
Our installation experts at SiDEX recently helped the Henderson family transform their home in Johnson Creek, Wisconsin, by removing two outdated windows and installing a brand-new patio door.
The project brought in more natural light, improved energy efficiency, and provided seamless access to the backyard. This upgrade is more than cosmetic - it’s a functional improvement that adds long-term value to the home while enhancing everyday comfort.
In Wisconsin communities like Johnson Creek, where summers bring humid heat and winters deliver bitter cold, the right patio door is crucial.
Drafty windows or poorly installed doors can let in unwanted air, raising energy bills and creating uncomfortable living spaces.
By replacing the windows with a secure, insulated patio door, the Hendersons gained durability, beauty, and improved climate protection - all essential for Wisconsin’s varied weather and soil conditions that can affect home foundations.

WINDOW-TO-PATIO DOOR CONVERSION: THE CHALLENGE IN WISCONSIN HOMES
Converting two double-hung windows into a single patio door is not a standard remodel. This project required careful planning, precise masonry work, and professional installation to avoid compromising the home’s structure. Common issues like brick removal, framing modification, and weatherproof sealing made this job far more complex than a standard window replacement.
OUR PROVEN PATIO DOOR INSTALLATION PROCESS
Window Removal
Our team began by carefully removing the existing windows:
- Interior trim and casing were removed to expose the frame.
- Caulk and nails securing the windows were cut.
- Each sash and frame was detached without damaging the surrounding brick or drywall.
Brickwork Preparation
To create the proper rough opening for the new patio door:
- The exterior brick was scored along precise cut lines.
- An angle grinder with a masonry blade was used to create smooth edges.
- Brick was carefully removed and cleaned for a professional finish.
Framing Modifications
Structural adjustments were made to ensure the opening could support the new door:
- Old window framing was removed.
- A new rough opening was framed with a header, king studs, and trimmer studs for stability.
- The opening was leveled, squared, and reinforced to handle the weight of the patio door.
Patio Door Installation
With the space prepared, the new patio door was set in place:
- Flashing and sill tape were applied for moisture protection.
- The door was dry-fit, shimmed, and secured to manufacturer specifications.
- A final check confirmed perfect alignment, level, and square.
Insulation & Sealing
To maximize energy efficiency:
- Low-expansion spray foam was applied around the frame.
- Gaps were sealed with caulk inside and out.
- Flashing and a drip cap were installed to divert rainwater away.
Interior Finishing
Finally, the interior was completed with:
- New trim and casing.
- Clean finishing for a polished look.
