Why Tallgrass

We are a family and locally owned construction company, and we have been building decks, covers, pergolas, and siding across Manhattan and the surrounding towns since 2015. Our crews bring over two decades of combined trade experience to every project, from a first deck to a full siding replacement.

We are a certified LP SmartSide installer and a Heartland Pergolas dealer, and TimberTech is the composite decking line we run almost exclusively. Those credentials are checkable, and they are part of why we can speak plainly about which materials make sense for your project and which do not.

Every estimate is free, and we handle the full permitting process on any project that needs one. We are licensed and insured, the way you would want a company handling your home to be. Kansas summers run hot and humid, winters bring hard freezes and thaws, and hail shows up most years, which is why the right material and a properly built structure are worth talking through before anyone picks up a hammer.

Where We Build

We build the same four services everywhere on this list: decks, deck covers and screened porches, pergolas, and siding, whether your project is in Manhattan, Junction City, Wamego, Riley, Westmoreland, or Alma. Some contractor sites make it look like certain services are only available in certain towns; that is not how we operate. The same crew travels to every town on this list, so what you can build depends on your property and your budget, not which town you live in.

Help Us Build Our Reviews

We are still building our review presence online. Right now, Facebook is where our reviews live. If we built your deck, your cover, your pergola, or your siding, we would genuinely appreciate a few minutes of your time to leave one there. It helps other Manhattan homeowners get a sense of the work before they call.

Common Questions

No. Every estimate is free, on every service line we offer. We come out, look at your property, talk through what you have in mind, and give you a real sense of what is involved. There is no cost and no obligation to move forward. We do not promise a specific turnaround, but reaching out is always the first step.

Get a Free Estimate

Every estimate is free, and there is no pressure to move forward. We ask for a budget range below so we can scope your project realistically instead of guessing, and one of us will follow up to talk through the details. You can also just call us directly.

This is a range, not a commitment. It just helps us scope your estimate to something real.
