Drag the slider to see one Manhattan-area deck go from worn and tired to fully rebuilt, same structure, same spot in the yard.


A full deck rebuild for a Manhattan, Kansas homeowner, same footprint, all new material.
What We Build in Manhattan
A new deck, a covered space to sit outside more of the year, a pergola, or new siding: the same crew handles it start to finish.

Decks
We build new decks in composite and pressure-treated lumber, and we handle full deck refurbishment on structures that are still sound underneath.

Deck Covers & Screened Porches
A roof cover turns a deck into a space you can use through more of the year, over a brand new deck or one you already have.

Pergolas
As a Heartland Pergolas dealer, we build pergolas in two materials: low-maintenance PVC or custom cedar for a more traditional, natural look.

Siding
We install vinyl, fiber cement, and engineered wood siding, including the LP SmartSide line we are certified to install.

More Finished Projects
These are recent decks, covers, pergolas, and siding projects finished across Manhattan and the surrounding towns. Every job here was built by the same crew you would meet on your own project.

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.
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 decks, deck covers and screened porches, pergolas, and siding in every town we serve. 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.
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.
We build in Manhattan, Junction City, Wamego, Riley, Westmoreland, Alma, and the surrounding communities. It is the same four services everywhere on that list: decks, deck covers and screened porches, pergolas, and siding. See our full service area page for more detail on the towns we cover, or give us a call if your town is not listed.
We handle the full permitting process for you. Requirements vary by project and by jurisdiction, but as one example, the City of Manhattan requires a permit for a new deck, or for replacing an existing deck, when it sits more than 30 inches above the ground. We walk you through what applies to your specific project before work starts.
So the estimate you get is for the project you can actually build, not three or four bids across different materials that were never in your range to begin with. Telling us your budget up front means we can scope the visit around a plan you could really move forward with, instead of wasting your time or ours. That is time we would rather spend building.
First, we come out and look at your property in person. From there, we scope the project with you, and if a permit is needed, we handle that process too. Once everything is set, our crews build it. Warranties apply to specific products, and we spell out exactly what is covered on that service's own page, for decks, siding, or whatever else we build.
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.
