Why Edwardsville homeowners call us

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

Edwardsville is home base for Threshold Builders - our crew lives here, our trucks are parked here, and most of the decks we build every year go up within a few miles of downtown. That matters more than it sounds: we know how Madison County clay soil heaves through freeze-thaw cycles, so every footing goes below the 30-inch frost line. We know the City of Edwardsville permit office and what its inspectors look for at framing. And when you call about a warranty item three years from now, we are ten minutes away, not two counties over.

We build across the whole city - established neighborhoods like Leclaire and Grandview where a new deck has to respect a hundred-year-old house, newer subdivisions off Governors’ Parkway and Route 157 where builders left behind a bare 10x10 pressure-treated platform, and lake properties around Dunlap Lake where the view deserves better railing than a wall of 2x2 balusters.

Edwardsville projects skew toward mid-size and large composite decks - the most common build we quote in town is a 300-400 sq ft composite deck with aluminum or cable railing.

Deck services in Edwardsville

Everything a Edwardsville deck needs, from one crew.

Composite deck construction

Trex and TimberTech builds with hidden fasteners and 25+ year fade and stain warranties. No staining, no splinters - the deck Edwardsville summers deserve without the maintenance weekends.

Wood deck construction

Properly built pressure-treated decks for budget-conscious projects - bolted ledgers, frost-depth footings, and framing that stays flat. Good wood decks start with good structure.

Deck replacement

Full tear-off, haul-away, and rebuild to current code. Demolition and disposal are line items in your quote - our crew handles them, not a subcontractor and not you.

Deck repair

Loose railings, soft boards, wobbly stairs, storm damage. Repairs in Edwardsville are usually scheduled within days - we do not park small jobs behind a season of big ones.

Deck maintenance

Resealing, re-staining, board swaps, and hardware checks - on decks we built and decks we did not. Maintenance now is the cheapest deck you will ever buy.

Railings, stairs & add-ons

Cable and aluminum railing, built-in benches, lighting, and pergolas designed with the deck - not bolted on later. One structure, one crew, one warranty.

Deck questions from Edwardsville homeowners

Real questions we answer at Edwardsville walkthroughs.

Do I need a permit to build a deck in Edwardsville, IL?

Yes. The City of Edwardsville requires a building permit for decks, including plan review and inspections at framing and completion. We prepare the drawings, submit the application, and meet the inspector on site - you do not have to deal with the permit office at all. Approval usually takes one to two weeks.

How much does a custom deck cost in Edwardsville?

Most Edwardsville composite decks we build land between $18,000 and $32,000 depending on size, height, and railing. Pressure-treated wood decks typically run $9,000 to $16,000. Every quote is itemized line by line, so you can see exactly where the money goes and adjust the scope before we start.

How deep do deck footings need to be in Edwardsville?

Footings must reach below the local frost line - 30 inches in Madison County. The clay soil around Edwardsville moves significantly through winter freeze-thaw, so we pour concrete footings below frost depth on every build. Shallow footings are the number one cause of the leaning, wavy decks we get called to replace.

Can you replace my existing deck in Edwardsville?

Yes - deck replacement is roughly half our Edwardsville work. We demo the old structure, haul it away, and rebuild to current code on new footings. If your frame is still sound, a resurface with new composite decking and railing can save real money; we will tell you honestly which route makes sense after a walkthrough.

Do you build decks near Dunlap Lake or in older neighborhoods like Leclaire?

We build all over Edwardsville, including Dunlap Lake waterfront lots and historic neighborhoods like Leclaire. Older homes and sloped lake lots each bring their own structural considerations - ledger attachment to older framing, taller support posts, stair runs on grade changes - and we design for those at the quote stage, not mid-build.

How long does a deck build take in Edwardsville?

Once the permit is approved, most Edwardsville decks take one to two weeks from breaking ground to final inspection. Larger multi-level projects can run three weeks. We give you a schedule before we start and we show up when we say we will.
