We've been working in Mt Prospect, IL for over 20 years. That's long enough to know which wood species perform well here, how to prep a substructure so it doesn't shift, and where most DIY decks go wrong. We pick lumber by hand for tight grain and minimal warping potential before a single board gets cut.
We don't hand you a finished deck and disappear. Every wood deck we build gets a proper sealer application before we wrap up. That step protects the wood from moisture intrusion and UV damage from day one. You're not calling us a year later because the boards are already splitting.
