What homeowners say
"Our old deck was rotting off the house. Tom showed us the ledger damage, fixed the rim board before anything else, and the new composite deck went up in eight working days. Two winters in, not a single board has moved."
"The quote was per square foot, so when we went two feet deeper we knew exactly what it added. No surprises at the end."
"They raked up every screw and sawdust pile each night. My kids were playing in the yard the whole week."

A small crew that builds one deck at a time
I started Bayshore in 2012 after eleven years framing houses for other builders. I wanted to do outdoor work properly: the parts you never see, like flashing the ledger, sizing the beams and digging the footings deep enough for our frost, are the parts that decide whether a deck lasts 8 years or 30.
We are four people and one trailer. I do every site visit and every quote myself, and I am on the job most days. We take about 30 decks a year, so you will not be juggled between three crews.

Questions we hear every spring
When should I book for a summer deck?
February to April. Our build calendar for June and July usually fills by the end of April. Fall builds, September to early November, are easier to get and lumber is often cheaper.
Do I need a permit for a deck in Green Bay?
Yes, for nearly every attached deck and any deck over 30 inches high. We draw the plan, file the permit and meet the inspector at the footing and frame stages. The fee is passed on at cost.
Composite or cedar?
Cedar costs less up front and looks warmer, but it needs cleaning and sealing every 2 to 3 years. Composite costs about 20% more and needs only a spring wash. Most of our clients pick composite for the decking and cedar for trim or a cap rail.
Can you build over my old deck frame?
Only if the frame passes inspection. Most frames from the 1990s were set on shallow footings and use undersized joists, so we usually replace them. We will show you what we find before you decide.
How do payments work?
30% when you sign so we can order materials, 40% after the frame inspection, and the last 30% after the final walk-through. We take check, ACH or card.
What does the warranty cover?
Our workmanship for 5 years: loose boards, wobbly rails, sagging stairs. The decking brand adds its own 25 to 50 year material warranty on composite boards.
