Our Story

How We Think About a Deck

We build and repair decks for homeowners around Madison, handling everything from a two-step back porch to a wraparound deck with built-in seating. Most of us ended up here because we like outdoor carpentry better than framing houses nobody sees once the drywall goes up.

If you're on this page, your deck probably has a problem, boards that cup and hold water, a railing that shifts when someone leans on it, or a ledger board pulling away from the house. We re-flash the ledger connection, replace joist hangers that have rusted through, and reset posts on proper footings so the fix lasts past one freeze-thaw cycle.

Why Choose Us

What you get when you hire us

None of this is complicated. It is mostly just doing what we said we would do.

Licensed and Insured

You're covered if a footing hits a buried line or a board drops off a ladder, certificates are available anytime.

Permits Pulled Right

Deck footings and guardrail height both get inspected here, and we schedule those inspections so the job passes the first time.

We Clean Up After

Old decking gets hauled off the same week we tear it out, not left stacked against your fence for a month.

Written Quotes

The quote lists lumber species, fastener type and railing style, so there's no guessing what you're paying for later.

On-Schedule Builds

Wisconsin weather moves fast, so we build in a rain buffer and still hit the finish date we give you.

Our Own Crew

We don't hand the project off to a sub for stairs or railings, the people who set your joists are the ones who finish the job.

Common Questions

Things people ask us

Questions about who's doing the work and how we operate.

How long have you been building decks?
Deck building and repair has been the focus of this work for years, covering everything from simple board replacements to full custom builds. Experience includes both new construction and fixing decks that other contractors built incorrectly.
Do you use your own crew or subcontractors?
The same crew handles framing, decking and railing work from start to finish on every project, rather than handing pieces off to different subcontractors. That keeps the people who know the job's history on site through the whole build.
Can I see examples of past deck work?
Photos of completed decks, including before-and-after shots of repair jobs, are available on request. Seeing a similar project, whether it's a multi-level build or a composite resurface, helps when deciding on materials and layout.
Why hire a smaller deck builder instead of a large company?
A smaller crew means the people quoting the job are the same ones building it, so details discussed during the estimate don't get lost in translation. Scheduling also tends to be more flexible than with larger outfits juggling dozens of crews.
Where are you based?
Deck building work is based in Madison, Wisconsin, with service extending to surrounding towns within roughly a 50-mile radius. That local base means familiarity with Madison's permit process and inspection requirements.
What's your availability like?
Spring through fall is the busiest season for deck construction in Wisconsin, so booking a few weeks ahead is worth doing for anyone planning a summer deck. Winter has more open scheduling, though frozen ground limits footing work until things thaw.
Do you clean up the job site when you're done?
All scrap lumber, old decking, cut-offs and packaging get hauled away at the end of the job, not left for the homeowner to deal with. The yard gets a final walkthrough to check for stray screws or nails before calling the job complete.
What happens if something gets damaged during construction?
Insurance covers accidental damage to the property during a deck build, whether that's landscaping disturbed near a footing or siding affected during ledger board work. Any damage gets addressed and repaired as part of the job, not left as a separate problem.
Will you finish a deck another contractor started or abandoned?
Picking up a half-finished deck is possible, but it starts with an inspection of what's already built to check footing depth, framing and hardware before continuing. Sometimes existing work needs correcting before it's safe to build on top of it.
How can I tell the deck work is being done correctly?
Footings should go below the local frost line, around 42 inches in the Madison area, and joist hangers should be galvanized or stainless to match treated lumber. A homeowner can ask to see footing depth before concrete gets poured and should expect a permit inspection to sign off on framing before decking goes down.
