Estimates That Win Bids.
Renders That Sell.
Accurate construction cost estimates, detailed quantity takeoffs, and photorealistic 3D renderings — delivered in 48 hours. Trusted by contractors and architects across all 50 US states.
Built by Estimators, For the People Who Build America
Nexa Estimating was founded with one goal: give contractors and architects access to the kind of accurate, fast, and affordable estimating that used to be reserved for large firms with big budgets.
Over the past decade, we have worked on everything from single-family homes in suburban Texas to large-scale commercial developments across the Southeast and Southwest. We understand the pressure of bid deadlines, the cost of estimation errors, and what it takes to put together a number you can actually stand behind.
Our team specializes exclusively in construction estimating and architectural rendering — no side projects, no generalist consultants. Just people who live and breathe takeoffs, material costs, labor rates, and photorealistic visualization every single day.
We are registered and operating in Austin, TX, serving clients in all 50 states. Whether you are a general contractor chasing a commercial bid or an architect trying to validate a design budget before presenting to a client — we treat every project like our name is on the line. Because it is.
Across 30+ states, residential to large-scale commercial.
Most estimates and renders delivered faster than any local firm.
Our work wins bids. Clients come back because results speak.
Why Contractors and Architects Choose Nexa
We Only Do This
Estimating and rendering is all we do. That focus means every person on our team is a specialist — not a generalist who estimates between other projects.
Speed Without Sacrificing Accuracy
Our process is built for turnaround. Most residential estimates in 24 hours, commercial in 48. We do not rush the numbers — we have built a workflow that makes speed possible without cutting corners.
Formatted the Way You Work
We do not send you a number on a napkin. Our estimates are formatted for your workflow — CSI division format, Excel, or whatever your bid submission requires. Renders are delivered in print-ready resolution.
Our Process
A Dedicated Team, Not a One-Person Show
Behind every estimate is a team of experienced estimators who have worked across every major trade — structural, MEP, civil, finishes, and site work. Our rendering team works alongside them, which means when you order an Estimate + Render package, both sides communicate rather than working in silos.
Every deliverable is reviewed before it leaves our desk. We do not send first drafts and ask you to catch the mistakes. Quality control is built into the process.

Client Testimonials
"Nexa turned around a full commercial takeoff in under two days. The level of detail was better than firms I've paid three times as much. We won the bid."

"Fast, accurate, and they answer every message. That alone puts them ahead of most people in this industry. I send every project to Nexa now."
