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.
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.

FAQs

Yes. We set up a temporary kitchen in your basement or garage, build temporary insulated walls with plastic sheeting, and run negative-pressure systems to pull dust out the window. Most clients tell us the home stayed more livable than they expected. They kept cooking dinner, hosting friends, and going about their week.
A custom home takes about a year of pre-construction (lot evaluation, civil engineering, septic, well, driveway, architectural plans, permits) before we break ground. From there, build time is typically 12 to 18 months depending on size and complexity. We’ll walk you through every cost upfront, including the soft costs most builders gloss over, so the budget you sign is the budget you live with.
Yes. We’re licensed real estate agents through Chesco Realty. Before you commit to a piece of land, we evaluate whether it’s actually buildable: zoning, setbacks, easements, septic feasibility, utility access, and driveway permitting. On one project, we caught a missing PennDOT driveway permit on a state highway during plan review. The client’s own civil engineer had missed it.
You get a JobTread account with daily field reports, photos, the live budget, the schedule, and every file. We meet you on site for weekly walk-throughs. Bring your family. Ask any question. Most clients tell us the transparency is the part they didn’t know they needed.
We don’t draft in-house. We have long relationships with architects and civil engineers across Chester County, and we’ll match the right one to your taste, budget, and project type. If you already have plans, we’ll review them and flag anything that needs to be addressed before you spend more.
It depends on what we’re building. Kitchen remodels start around $60,000 for a stock-cabinet refresh and run $180,000 and up for custom cabinetry and a new layout. Additions and whole-home renovations start at $300,000. Custom homes start at roughly $400 per square foot for the standard tier. We’ll build you a detailed line-item budget before you sign anything, and we’ll tell you honestly if buying and renovating an existing home makes more sense than building new.
