Why Collinsville homeowners call us

Built for Collinsville - the lots, the soil, the permits.

Collinsville has some of the older housing stock in the Metro East, and older homes often come with decks built long before today’s codes - undersized footings, ledger boards nailed instead of bolted, railings that wiggle when you lean on them. Those are not cosmetic problems; ledger failure is how decks collapse. A large share of our Collinsville work is tearing those structures off, hauling them away, and rebuilding to current code with a permit and inspections.

We work across the whole city - the established neighborhoods up the bluff with views that deserve a real deck, the streets around downtown and Main Street, and the newer subdivisions toward Route 157. And when a deck still has life in it, we say so: new boards, tightened framing, and resealing is honest work that buys you years, and we quote it just as carefully as a full rebuild.

Code-compliant replacement is the most common Collinsville project we quote - old deck off and hauled away, new composite deck on proper footings, usually inside two weeks.

Deck questions from Collinsville homeowners

Real questions we answer at Collinsville walkthroughs.

Do I need a permit to replace a deck in Collinsville, IL?

Yes. The City of Collinsville requires a building permit for deck replacement and new construction, with plan review and inspections. Rebuilding on an old deck’s footprint does not exempt you - the new structure must meet current code. We handle the entire permit process on every job.

How do I know if my older Collinsville deck is unsafe?

The big three: a ledger board attached with nails instead of structural bolts, posts sitting on shallow or surface footings, and railings that move when pushed. Soft or springy boards and rusted joist hangers are also warning signs. We inspect all of it during a free walkthrough and give you a written, honest assessment - repair when repair is right, replacement when it is not.

How much does deck replacement cost in Collinsville?

Tear-off, haul-away, and a new composite deck typically runs $17,000 to $30,000 in Collinsville depending on size and railing. Rebuilding in wood runs $9,000 to $16,000. Demolition and disposal are line items in the quote, not surprises at the end.

Can you build a deck to take advantage of a bluff view?

Yes. Collinsville’s bluff neighborhoods have some of the best views in the Metro East, and an elevated deck built for the sightline - cable or slim aluminum railing instead of bulky pickets - completely changes how the house lives. Elevated builds get engineered posts, bracing, and frost-depth footings as standard.

Do you handle deck repair and maintenance in Collinsville?

Yes. Board replacement, railing tightening, stair rebuilds, resealing and re-staining - we maintain decks we built and decks we did not. Small repairs are usually scheduled within days, and honest maintenance now is the cheapest deck you will ever buy.

How long does a Collinsville deck replacement take?

Demolition typically takes a day, and the rebuild takes one to two weeks depending on size. Start to finish - including the City of Collinsville permit - most replacements are done within a month of approving the quote.
