1987

The year Gene Ostrander started siding homes in Fort Collins.

It started with one house, and the next one, and the next.

Gene Ostrander built the business one house at a time and bought his first on-site forming machine in 1994. His daughter Kate took over in 2014 and still runs it the same way. Our crews live here. They drive past the homes they’ve sided, and they know the people who live in them.

Today

Three counties, from Estes Park to Greeley.

Four things we don’t compromise on.

They’re the same four things David started with. They’re why people call us back for the roof, the gutters and the windows.

01Measure carefully

Every wall, opening and roof plane, in person. Your price is written and itemized before anything is ordered.

02Build it once

Seamless steel, formed to your house, installed so it’s the last exterior your home will need.

03Respect the home

Floors protected, yards cleaned up every day, and crews you’re comfortable having around.

04Stand behind it

A lifetime warranty in writing, from a company that will still be here to honor it.

Our own machines, run by a Fort Collins family.

We own the forming machines, we buy the steel coil, and we write the warranty ourselves. You get seamless steel and a lifetime warranty from a Fort Collins family that answers its own phone.

Luis and Cody treated our home with real care. Friendly, professional, and they left the yard cleaner than they found it every single day.

Great gutters and great windows. We get heavy spring snow in Windsor and the gutters handle every bit of it.
