Built on Craftsmanship. Driven by Customer Service.

Since 1984, Quality Installation & Home Improvement Co. has helped homeowners throughout the St. Louis Metro East improve, protect, and enhance their homes with expert craftsmanship and dependable service. What began as a trusted installation company has grown into a full-service home improvement contractor known for quality products, honest advice, and lasting customer relationships.

For more than four decades, we've remained committed to doing things the right way—never cutting corners and always treating every home as if it were our own.

Our Story

Quality Installation began in 1984 as an installation subcontractor serving window and siding companies throughout the region. Working alongside numerous manufacturers and contractors gave us valuable firsthand experience with a wide variety of products, installation methods, and warranty programs.

Over those years, we learned which products delivered long-term performance, which brands consistently stood behind their warranties, and which installation practices produced the best results. That experience became the foundation of our business.

In 1994, we expanded into retail home improvement services, allowing homeowners to work directly with our experienced team from product selection through professional installation.

Today, we continue to apply the knowledge gained over decades in the industry to help homeowners make confident, informed decisions for their homes.

Our Philosophy

A home improvement project is more than replacing windows or installing a new roof—it's an investment in your home's comfort, value, and protection.

That's why we focus on:

Honest recommendations without high-pressure sales tactics
Premium products from trusted manufacturers
Skilled installation performed with attention to detail
Clear communication throughout every project
Standing behind our work long after installation is complete

Our goal is simple: deliver quality that homeowners can rely on for years to come.

Quality Products. Trusted Partners.

The products we install are just as important as the craftsmanship behind them.

After decades in the industry, we've built relationships with manufacturers that consistently provide dependable products backed by strong warranties and responsive customer support. We carefully select the brands we offer because we know our reputation depends on the performance of every product we install.

Whether you're replacing your roof, upgrading windows, installing new siding, or remodeling your home, you can feel confident knowing you're receiving products chosen for durability, energy efficiency, and long-term value.

Committed to Exceptional Customer Service

Customer service has always been the heart of our company.

From promptly returning phone calls to carefully managing every installation, we believe every interaction matters. Our team works hard to ensure each project is completed professionally, efficiently, and with the level of care our customers deserve.
