Defined Scope. Clear Communication.
Predictable Results.
Most construction problems come from unclear scope and undefined expectations — not poor craftsmanship. Our process eliminates that risk.
Structured Review
We begin with a focused project review to understand your goals, property conditions, budget range, and structural constraints before any design decisions are made.
Design & Scope
Layouts, materials, and structural details are defined upfront to eliminate ambiguity, prevent scope drift, and protect your investment.
Planning & Scheduling
Timelines, sequencing, and responsibilities are finalized before construction begins. Your project moves forward in a controlled and transparent manner.
Professional Execution
Work is executed according to plan with defined checkpoints, proactive communication, and accountability from start to finish.
How process protects pricing: Clear scope definition before construction prevents pricing instability caused by undefined materials, structural revisions, or design changes.

“Nick worked closely with us to ensure we had the deck we envisioned. The crew was professional, efficient, and delivered exactly what was discussed. We couldn’t be happier with the final result.”— Andy
“Tech Five was the only company that returned our call — and did so within 24 hours. The crew was polite, efficient, and the project stayed on schedule.”— Bill
“Always responded to our questions. We were informed daily of progress. Completed on schedule. The final result exceeded our expectations.”— Sarah
“Our multi-level deck turned out even better than we imagined. The crew handled the sloped lot perfectly and the finished product looks like it was always part of our home. Worth every penny.”— Mike
“From the initial consultation to the final walkthrough, everything was explained clearly. No surprises on the invoice, no hidden fees. The AZEK decking they recommended has been holding up beautifully.”— Jennifer
“They gave us a 3-week timeline and finished in exactly 3 weeks. The crew showed up on time every day and cleaned up after themselves. Really refreshing to work with contractors who do what they say.”— Tom
“The picture-frame border detail they suggested really set our deck apart from the neighbors. Small touches like that show they actually care about the finished product, not just getting it done fast.”— Karen
“Our old deck had some structural issues they uncovered during demo. Instead of just patching it, they explained exactly what was wrong and fixed it right. Peace of mind knowing it’s built to last.”— Dave
“We got quotes from 5 different companies. Tech Five wasn’t the cheapest, but they were the most thorough in explaining what we were getting. Two years later, still looks brand new.”— Lisa
“Had a question about maintenance a year after installation. Nick called me back the same day and walked me through everything. That kind of follow-up is rare these days.”— Steve
“They handled all the permits and inspections with the city. Didn’t have to deal with any of the paperwork headaches. The inspector even complimented the quality of the work.”— Rachel
“This was our first time hiring a contractor for a major project. Tech Five made it easy. Clear proposals, regular updates, and the final result speaks for itself. Highly recommend.”— Matt
“Three of our neighbors have used Tech Five now. There’s a reason for that — they do quality work and stand behind it. Our screened porch has become our favorite room in the house.”— Linda
“Living near Lake Winnebago, we needed something that could handle the moisture and wind. They spec’d everything for our conditions and it’s held up through two harsh winters already.”— Chris
“The covered deck they built matches our home’s roofline perfectly. Guests always think it was part of the original house. Exactly what we wanted.”— Nancy
Founder-Led.
System-Driven.
Founded in 2018, Tech Five Design & Build was built after seeing firsthand how avoidable construction problems develop — not from bad materials, but from unclear scope, rushed decisions, and undefined expectations.
We begin with design. We define the scope clearly. We align expectations before construction begins. Then we build with precision.
Growth is intentional and capacity-driven — not volume-driven. We protect quality before expanding volume.
