Quality Home Building Services in Downingtown
Downingtown sits in the western part of Chester County where the Brandywine forks and the land opens into a mix of older neighborhoods, wooded hillsides, and properties with real room to build. McComsey Builders is a second-generation, family-owned home builder, founded by Bob McComsey Sr. in 1986 and run today by his sons Bob and Mike. We build custom homes, additions, kitchens, and accessory structures for Downingtown families who want a builder that treats every project as one of one, because every project we take on is.
The homes around Downingtown reward builders who study a site before they design for it. Lots near Marsh Creek State Park carry soil conditions and setbacks that ask for careful early work, and older homes in the closer-in neighborhoods often have character worth saving rather than removing. When you build a custom home in Downingtown with us, we come in early, evaluate buildability, help source the right architect, and stay with you from the first conversation through move-in day. We have built on open acreage and on tighter lots, new construction and full renovations, and that range is what forty years in Chester County makes possible.
We are boutique by design, which means we keep our team small and our attention close. Every home and every kitchen is drawn with you. We build the cabinetry in our own shop, to the dimensions and details you chose, and when a tree comes down on your property we mill it into the floors, beams, or counters of the new home, so the material is as specific to your place as the plan is. If you want to add on to your Downingtown home or take on a full interior renovation, you get that same level of attention, plus dust walls, temporary kitchens, and negative-pressure containment so your family can live at home while we work.
The process stays visible the whole way through. Every McComsey client gets a JobTread login with daily field reports, photos, the live budget, and every file, and we walk the site with you each week. Our kitchens come in within 5 percent of the original budget, and we hand you the keys when we said we would. We are an Andersen Certified Contractor and licensed in Pennsylvania under PA015145, and we build with the confidence that comes from two generations of doing this work one project at a time.
Downingtown is a market we know well and take seriously. If you are ready to talk about what you want to build, we are ready to listen.
Our Downingtown Remodeling Services
Custom Home Building
A home built around how your family lives, on the lot you have chosen or one we help you find. We come in early, evaluate buildability, source the right architect, and stay with you from the first walkthrough to the day we hand over the keys. Every home we build is one of one.
Home Additions and Renovations
More room, better flow, modern systems, and a home that finally feels like your own. We build temporary kitchens, dust walls, and negative-pressure containment so your family can keep living at home while we work, including whole-home and major historic renovations other builders will not take on.
Kitchen Remodeling
Cabinets we draw with you and build in our own shop. New layouts, structural openings, stone counters, and a kitchen that finally fits how you cook and gather. Our kitchens come in within 5 percent of the original budget, and we hand you the keys when we said we would.
Accessory Structures
Horse barns, party barns, car barns, pool houses, and the structures that turn a property into the place your family wants to spend the weekend. We bring the same craft and transparent process to an outbuilding that we bring to the main house.
Commercial Construction
Tenant fit-outs and full ground-up commercial builds. We work directly with building owners, scope every line transparently, and protect the move-in date so your business opens on schedule.

Boutique by Design
Every home and every kitchen is one of one. We sit down with you, sometimes on lawn chairs in an empty house, and 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.
A Budget You Can See
You 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, so you see what we see, and we hand you the keys when we said we would.
Forty Years, Second Generation Hands-On
Our name has been on the trucks since 1986. Bob and Mike took over from their dad and build the company 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.

Our History in Downingtown
McComsey Builders has been building in Chester County since Bob McComsey Sr. founded the company in 1986. His sons Bob and Mike run it today, the same family name, the same small team, and the same standard their father set. Downingtown has been part of our service area for a long time. The community sits along the East Branch of the Brandywine Creek, and the mix of established neighborhoods, newer development, and open parcels near places like Kerr Park and Kardon Park gives us the full range of work we like best: new construction on acreage, full additions on older colonial homes, kitchens drawn from scratch with families who have lived in the same house for twenty years. We are based in Parkesburg, PA, a short drive west, which means our team is on site in Downingtown without the friction that comes with a larger market builder spread thin across three counties. The McComsey name is on every job here, and we build every one of them like our reputation depends on it, because it does.
Frequently Asked Questions - Downingtown Remodeling
Does McComsey Builders build custom homes in Downingtown, PA?
Yes. Downingtown is one of our core markets, and we have been building in Chester County since 1986. We build on your lot or help you find one, and we stay with you from the first site visit through the day we hand over the keys. Our custom home building page covers how we approach the whole process.
Can you add on to an existing home in Downingtown?
Yes. Home additions are a large part of our work across Chester County. We evaluate the existing structure, match materials and character to what is already there, and plan the phasing so your family can keep living at home while we build. Learn more on our home additions and renovations page.
Do you build barns, pool houses, or other accessory structures in Downingtown?
Yes. On the larger lots west of Downingtown, near the open land around Marsh Creek State Park, we build horse barns, party barns, car barns, pool houses, and basketball courts with the same craft we bring to the main house. See our accessory structures page for the full range of what we build.
How does McComsey Builders keep a Downingtown project on budget?
Every client gets a JobTread login from day one with daily field reports, photos, and a live budget that updates as the project moves. We walk the site with you each week so nothing is a surprise. Our kitchens come in within 5 percent of the original budget, and we deliver the keys on the schedule we committed to at the start.
What makes McComsey different from a larger volume builder in Chester County?
We are boutique by design. We take on one project at a time with a small, senior team, so you always have Bob or Mike on your site, not a rotating crew of subcontractors. We draw your cabinets with you and build them in our own shop. When trees come down on your property, we mill them into your floors and beams. That level of craft and attention is the whole point of the company, and it is what forty years in Chester County has taught us to protect. You can read more about how we work on our about page.
Does McComsey Builders handle kitchen remodeling in Downingtown?
Yes. Kitchen work is one of our signature services, and it is where our in-house cabinetry makes the most visible difference. We draw the kitchen with you, build the cabinets in our own shop, and plan dust-mitigation from the start so your family can live at home through the work. See the full approach on our kitchen remodeling page.
