Who We Are
McComsey Builders is a second-generation family construction company in Chester County, Pennsylvania. Bob McComsey Sr. founded the company in 1986. Today, his sons Bob and Mike run it together — building custom homes, additions, kitchens, barns, and commercial projects across Chester County and the surrounding area, with the same family name on every job and the same standard their dad set forty years ago.
What’s evolved is the way the work runs day to day. Cabinets we build in our own shop. JobTread on every project. A tighter team. The architect partnerships we’ve built across decades of work.
The McComsey difference
Our name has been on the trucks since 1986 — and on every project we’ve ever built. Here’s what that means when it’s on yours.
We’re boutique by design. Every home and every kitchen is one of one. We start by sitting down with you, sometimes literally on lawn chairs in an empty house, and we draw cabinets specific to how you cook and gather. When trees come down on your property, we mill them into the floors, beams, and counters of your new home.
You’ll get a JobTread login with daily field reports, photos, the live budget, every file, and a direct line to our team. Weekly walk-throughs happen on site. You see what we see. Our kitchens come in within 5% of the original budget, and we hand you the keys when we said we would.
Bob and Mike took over from their dad, and the company they are building looks like the one they grew up around: tight communication, in-house cabinetry, a trusted bench of architects and trade partners, and a small team that does serious work. The McComsey name is on every job, and we treat your home like it is our legacy too.
What we stand for
A family name on a building permit is a promise. Here’s what that promise means in practice — to the people who hire us, the people who work for us, and the trade partners we build alongside.
Our mission
To be the most respected builder in Chester County — not just for the homes we create, but for the way we treat the people who hire us, the people who work for us, and the trade partners we build alongside.
Our core values
We honor the trust given to us. We're transparent about costs, schedules, and the work itself. When we tell you something, you can take it to the bank.
Every project gets the attention we'd give our own home. We don't cut corners on quality or hide problems. The McComsey name goes on every build, and we treat that name like the legacy it is.
Long-term success comes from taking care of people first — our clients, our team, and our trade partners. We invest in relationships before we worry about margins.
Forty years in, we still review every project for what we could have done better. Every job is a chance to refine the way we work.
Process
We created six clear steps so that once we start building there aren’t surprises. We take our time getting the budget right so the build can move fast and we limit disruption to your life.
It starts with a conversation. We ask who sent you our way, whether you have plans yet, and the kind of budget you’re working with. The goal is to make sure we’re the right team for what you have in mind before either of us spends another hour on it.
We come out to the property, walk the space with you, and review your plans if you have them. If you don’t have plans yet, we take photos and talk through the scope of work. You get the benefit of forty years of doing this work, telling you straight what will and won’t work and how a renovation or addition really comes together.
We send the plans out to our trade partners, scope every piece of the job, and on bigger or more complex projects, bring them back to the property for a second walkthrough. Their input is what gets us to a real, line-item budget.
We take the trade partner proposals, fill in anything missing, and build out a detailed Excel budget with specific line items. Then we sit down with you and walk every single line. You see why each piece costs and why, what’s included, and where there’s room to flex. By the time we're done, we're all reading the same numbers on the same page.
Once the budget feels right and we agree on a timeline, we lock it in as a signed approved order in JobTread. That's your starting point. As real-life decisions and changes come up along the way, every cost change gets documented against that baseline, so nothing’s ever a surprise.
Before we break ground, we introduce you to the people who’ll be running your project day to day. That means Mike, Evan, and your field lead. You’ll get their phone numbers, so that you know who to call, and any one of us is reachable when you need an answer.
