Deck & Porch Construction

New decks, rebuilt stairs and railings, and porch repairs built to the local code and inspected.

Deck & Porch Construction by ONIT Solutions

Decks and porches live outside in an Illinois climate, so what matters is the structure and the fasteners, not just the boards you can see. We build them to the local code, pull the permit, and have them inspected.

What we build and repair

  • New decks in treated lumber or composite decking
  • Stairs, landings and railings that meet current code
  • Replacing rotted boards, joists, posts and ledgers on existing decks
  • Front porch repairs: columns, railings, steps and ceilings
  • Resurfacing a sound frame with new decking and rails

The ledger board

Most deck failures start where the deck meets the house. We flash and fasten the ledger to current code, with the right bolts, not just lag screws, and we will tell you if an existing ledger needs to be redone before anything else is worth fixing.

FAQ

Questions about deck & porch construction

Do I need a permit for a deck?
In nearly every town we work in, yes, for a new deck or a structural repair. We pull it and schedule the inspections.
Composite or wood?
Composite costs more up front and needs almost no upkeep. Treated wood costs less and needs sealing. We price both if you are deciding.
Can you just replace the boards?
If the frame is sound, yes. We inspect the joists, posts and ledger first. Resurfacing a rotten frame is money wasted.
