StateLine Exteriors partnered with Timber Creek Sewer Company to convert an outdated garage opening into a finished, functional space that looks original to the building and supports daily operations.

A Search for a Capable Contractor That Almost Ended to a Clear Path Forward
Timber Creek Sewer Company in Platte City came to StateLine Exteriors after hitting a wall with other contractors. The project required multiple phases of work, and most companies they spoke with could only handle pieces of the scope. They were close to giving up on finding one contractor who could manage everything and were preparing for higher costs, multiple sales meetings, and overseeing the work themselves. They reached out to StateLine Exteriors, looking for clarity and one team that could handle the entire project.
Why the Existing Space Was Not Working
The building’s double garage doors no longer supported how the space needed to function. The goal was to create a professional customer entrance while also converting the interior into a usable studio space. This required removing the garage doors completely and rebuilding the exterior wall with windows and a walk-through door, all while making sure the finished result blended seamlessly with the original structure.
A Multi-Phase Solution Designed to Look Original
This project required more than a standard window or door install. The goal was to completely rework the former garage opening while making the finished space look like it had always been part of the building. StateLine Exteriors handled every phase with careful planning, structural precision, and close attention to visual continuity.
Services completed on this project included:
- Removal of two existing garage doors and all related hardware
- Installation of a concrete barrier for added structural support
- Framing of new walls tied into the existing structure using king and sister studs
- Installation of five ProVia windows in the newly built wall
- Construction of a walk-through door for customer and employee access
Solving Structural Challenges with Experience
This project went beyond a standard window or door installation. Converting garage openings into a finished wall required careful framing, proper integration with existing headers, and precise execution. Our team handled each phase with attention to detail, ensuring the new construction was secure, code-compliant, and visually seamless.
Homeowner Satisified with the Home Remodel
Having one contractor oversee the entire scope made the process far less stressful. Instead of coordinating multiple companies, the owner was able to rely on a single team to manage the details and deliver a finished space that met both functional and visual goals.
What the Owners Love Most About Their Garage Conversion
- A finished exterior wall that looks original to the building
- Natural light from the new ProVia windows
- A functional, professional entrance for customers
- One contractor managing every phase of the project
A Finished Space Built for Long-Term Use
What began as a complex, multi-phase challenge ended with a space that works better and looks like it was always part of the original design. This Platte City project is a strong example of how StateLine Exteriors handles more than standard installs by delivering thoughtful, well-executed solutions.
