Why Capitol Decks
A deck is only as good as the crew that builds it
- Built by a working carpenter
- Owner Jesus Rincon has spent 10+ years in the trade and is on your job site — not behind a desk. You talk to the person building your deck.
- Engineered for Wisconsin
- Frost-depth footings, proper ledger flashing, and materials chosen to survive Dane County freeze-thaw cycles year after year.
- Straight, written estimates
- Free on-site estimates with itemized materials and labor. No surprise change orders halfway through your build.
- Bilingual, local, accountable
- English and Spanish, locally owned in Sun Prairie, licensed and insured, and easy to reach from first call to final walkthrough.

What homeowners say
A few words from homeowners around Sun Prairie and Madison.
“Jesus and his crew rebuilt our back deck in composite and it changed how we use the yard. Clear written estimate, no surprises, and they cleaned up every night.”
Megan R. · Sun Prairie, WI
“They screened in our porch before the summer and the framing is rock solid. Bilingual crew, great communication, and the finish work is better than we expected.”
Dave K. · Sun Prairie, WI
“Our 20-year-old cedar deck looked done for. Capitol Decks replaced the bad boards, re-stained it, and it looks new again. Fair price and they showed up when they said they would.”
