Premium windows, siding, doors, and custom sunrooms. We combine architectural precision with master craftsmanship to transform your home.
Horizon Exteriors is a sunroom and pergola contractor in Kansas City, and our home exterior services in Kansas City run from replacement windows and siding to a new sunroom door. If you are planning exterior remodeling in Kansas City, one crew handles design, permits and the build.

We don't cut corners. Every project is built to the highest standards of durability and aesthetics.

We partner with leading manufacturers to provide products that stand the test of time.

We know Kansas City weather and architecture, ensuring solutions that fit your specific environment.
Most exterior projects in Kansas City touch more than one trade. Replacing windows exposes rotten trim. A siding tear-off finds soffit that has been holding water for years. Hire separate specialists for each piece and you end up refereeing between them about whose work caused what. We run the whole envelope with one crew, so responsibility never lands in a gap between contractors.
Every common style, from double hung to bay and bow, measured on site and installed by our own crew.
Vinyl, insulated vinyl, fiber cement and engineered wood, torn off to the sheathing rather than covered over.
Fiberglass, steel and wood, fitted to the actual opening with the frame checked for square and level.
Three season and four season builds, permitted and constructed as a real addition on frost depth footings.
Aluminium and louvered structures that need no staining and hold a wind load on properly sized footings.
Screened porches and glass enclosures, often built onto a sound existing deck without new foundations.
This metro swings about a hundred degrees between a January cold snap and an August afternoon, and spring reliably brings hail. Materials that behave perfectly in a milder market move, crack and fade here. Nearly every leak we are called out to repair is a flashing failure, not a product failure, which is why we care more about the detail at each opening than the brand printed on the box.
We measure at the house, never over the phone. Homes here have settled and very little is still square.
You approve a written scope and material selection before anything is ordered, so there are no mid-week extras.
We prepare and file both, including architectural review packets for Overland Park, Olathe and Lenexa subdivisions.
Installation is never subcontracted. A crew paid per unit is paid to finish, not to flash an opening properly.
The site is cleared each evening and swept with a magnet for fasteners before we leave.
We walk the finished work with you and adjust before the job is called done, not after.
We work Kansas City on the Missouri side, Overland Park, Olathe, Lenexa and Shawnee on the Kansas side, and Lee’s Summit and Independence to the east. That distinction matters more than it sounds. Permitting, inspection and HOA review differ genuinely by jurisdiction, and frost depth and soil behaviour are not the same on both sides of the line.
Horizon Exteriors LLC was founded in 2024 by Nathan Bowman. The crew is local and the person who quotes your job is the one you call later.
No. Installation is done by our own crew, which is the single biggest quality control decision a contractor makes.
We stop, photograph it and show you before anything is covered back up. Repairs are priced separately rather than quoted blind.
We prepare and file both, with product data and colour samples assembled into the submittal for you.
No. The measure and walkthrough are free and you keep the written scope whether or not you go ahead.
Yes. Windows with siding is the combination that genuinely saves money, because the flashing at every opening is done once.
