Common Questions

Decks & Patios Questions, Answered

Do I need a permit to build a deck in Duluth, MN?

In most cases, yes — decks over a certain size or height require a building permit in Duluth and surrounding municipalities. We handle the permitting for you as part of every project, so you don't have to deal with city hall yourself.

How long does it take to build a deck from start to finish?

Most deck projects run about 3–4 weeks from your first consultation to the final walkthrough — roughly a week for design and material selection, plus one to two weeks of build time (and permitting if it's required). We give you a realistic timeline at your consultation and build to the schedule we quote.

Do I have to wait until spring to build?

No. Spring and early summer book up fast, but we build spring through late fall and take consultations year-round. Reach out anytime and we'll get you on the schedule for the next available slot instead of waiting for the summer rush.

Do you guarantee your deck work?

Yes. Every deck we build is backed by our workmanship warranty, on top of the manufacturer's material warranty. If something about the installation isn't right, we stand behind our work and make it right.
