About

Forty years,frame to finish.

Straight Flush Construction Services is one man's name on the contract, one man on the job, and a small group of partner crews who've worked beside him long enough to know how he wants it done.

Who's on the other end of the phone.

Corey "Big Cat" Castner has spent more than forty years building houses from the framing up — roofs, concrete, custom woodwork, additions, and everything that ties them together. He brought that experience to North Alabama about seven years ago and started Straight Flush around one idea: the founder should be on the job.

That isn't a slogan. It means the person who measured your roof is the person who wrote the number, the person who's on site when the tear-off starts, and the person who answers when you call in year five. There's no sales rep in between and nobody to point at when something needs fixing.

He is not from here, and he won't tell you he is. He's staying here, which for a roofing warranty is the part that matters.

"I've framed it, roofed it, poured it, and finished it. I've also been the guy called in to fix what somebody else did cheap. That second part is where most of what I know came from."

The rig you'll see in your driveway.

No unmarked trucks, no out-of-state plates. The truck, the trailer, and the King on the side are the same ones that show up for the inspection, the tear-off, and the final walk.
