Helping Contractors Bid Right and Build Profitably
We are a team of professional estimators dedicated to one thing — giving contractors the accurate, defensible numbers they need to win bids and protect their margins.
A Construction Estimating Team That Understands the Jobsite
Keystone Estimators is a construction estimating company founded by estimators who came from the trades. We have seen firsthand what happens when a contractor submits a bid built on rushed math or outdated pricing — and we built this company to fix exactly that problem.
For over 15 years, our team has been working alongside general contractors, subcontractors, home builders, and developers across the United States. We handle the estimating work so our clients can stay focused on what they do best — building.
Every estimate we deliver is reviewed by a licensed estimating professional before it leaves our desk. No guessing. No shortcuts. Just accurate, regionally priced numbers your whole team can rely on.
15+ Years of Combined Experience
Our estimators bring over 15 years of hands-on field and pre-construction experience across residential, commercial, and specialty trades.
Serving Contractors Across All 50 States
We work with contractors nationwide — pricing every project with current regional cost data so your numbers reflect your actual market.
Dedicated to One Discipline
Estimating is all we do. That focus is why our accuracy holds up when the project is done and the final costs come in.
No Contracts, No Retainers
You pay per project. Use us when you need us and scale up as your bid volume grows — no long-term commitments required.
Accurate Estimates Delivered the Right Way
We keep our process straightforward so there's no confusion about what you're getting or how long it takes.
You Send Us Your Plans
Upload your drawings, PDFs, CAD, or BIM files directly to us along with your bid deadline. We confirm scope and timeline within the hour and assign your project to the right estimator.
We Do a Thorough Takeoff
Our estimator reads your plans in full — not just the summary sheets. Every material, system, and scope item is counted and priced using current regional data for your specific market, not national averages.
A Second Set of Eyes Before Delivery
Every estimate goes through an internal quality check before we send it to you. We flag anything unusual, document our assumptions, and make sure the numbers are clean and ready to submit.
You Receive a Clear, Itemized Report
Your estimate arrives in Excel or PDF format — fully itemized, editable, and structured so you or your team can review every line without needing to call us for clarification.
We Stay Available Through Bid Day
If scope changes after delivery or an owner asks a question you need answered fast, we're reachable. Free revisions are included, and we don't disappear once the estimate is sent.
Priced for Your Market, Not a National Average
A concrete pour in Phoenix is not priced the same as one in Chicago. We build every estimate using local labor rates and material costs so your bid is competitive where you actually build.
What Contractors Say About Working With Us
"We have been using Keystone Estimators for the past three years and they have never missed a deadline. Every estimate comes back clean, itemized, and exactly what we need to submit a competitive bid. It has made a real difference in how many jobs we win."
"What I appreciate most is how straightforward the whole process is. I send my plans, they get back to me within 48 hours with a proper takeoff, and I can actually understand every line item. No confusion, no back-and-forth. Just a number I can work with."
"I was doing all my own estimates before I found Keystone. The time I was spending on takeoffs was cutting into my actual project management work. Now I send the plans over and focus on running the job. Their accuracy has been spot on with every project so far."
