Why Maniaci

The crew that measures your yard is the crew that builds in it

Most contractors our size subcontract the carpentry. We don't, and it's the reason the quality stays consistent from job to job. The people who walk your property on day one are the same people you'll see every morning until the last board is down.

We draw the plans, we pull the permits, and we hand you a written scope line by line before anything is ordered — so the number you agree to is the number you pay.

Ready to elevate your backyard?

Get a budget range in about a minute, or have us come measure. Either way, there's no pitch on the other end.
