Most siding arrives in 12-foot pieces and gets overlapped on your wall. Ours is rolled from steel coil in your driveway and cut to the exact length of every wall, so there are no seams for ice, water or insects to get behind.

1987

The year Gene Ostrander started siding homes in Fort Collins.

Two generations of doing it once, and doing it right.

Gene 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: measure carefully, build it to last, and stand behind it for life. Our crews live here, and they drive past the homes they've sided.

Steel log siding: the log-home look without the upkeep

How it's made, what it looks like up close, and who it's right for.

Good to know before you call.

Is steel siding better than vinyl in Colorado?

For most homes here, yes. Vinyl gets brittle in a cold snap and can crack when it's hit by hail or a stray rock. Our heavy-gauge G-90 galvanized steel holds up to both, has no seams for snow and water to get behind, and carries a finish guaranteed never to flake, peel or chip.

What does "seamless" actually mean?

Most siding and gutters come in fixed lengths that get overlapped at the joints. We bring the forming machine to your home and roll each piece from steel coil at the full length of the wall or roofline, so there are no seams where moisture, dirt or insects can collect.

Can you do siding, roofing and gutters together?

Yes, and it's usually the best value: one estimate, one crew, colors that match across siding, trim, soffit, gutters and roof, and one warranty from one local company.

Do you install steel log siding?

We do. It's popular around Estes Park and up toward Red Feather Lakes with homeowners who love the log-home look but are done with staining and chinking.

What does the lifetime warranty cover?

Our seamless steel siding, gutters, and soffit and fascia carry a lifetime warranty. We'll walk you through exactly what's covered for your project at the estimate and give it to you in writing.
