Quality Home Building Services in Unionville
Unionville is a village that earns its reputation quietly. The roads in East Marlborough Township roll past estate fences, open fields, and old stone farmhouses that have stood for generations, and the people who build here want homes that belong to that same tradition. McComsey Builders is a second-generation, family-owned custom home builder, founded by Bob McComsey Sr. in 1986 and run today by his sons Bob and Mike. For forty years, Chester County families have trusted our name on their homes, and this corner of the county is exactly the kind of place that work was built for.
The properties around Unionville ask for a builder who can read land. Larger lots, mature trees, stone outbuildings, and horse facilities are part of the character here, and they are part of the conversation we have before drawing a single line. When you build a custom home in Unionville with us, we evaluate the site first, help you source the right architect, and stay involved from the first walkthrough straight through to the day we hand over the keys. The home we design with you will not be a floor plan we have used somewhere else. Every home and every kitchen is one of one.
That same attention carries into every other kind of work we do here. Equestrian properties and large-lot estates often call for more than a main house. We build barns, horse facilities, pool houses, and car barns with the same craft we bring to a custom home, and they are designed to fit the property rather than look like an afterthought. If you want to add on to your existing home or restore an older stone farmhouse on your acreage, we take on that kind of complex work too.
We are boutique by design, which means we stay small enough to be hands-on. We sit down with you and draw cabinetry to fit how your kitchen actually works, then we build those cabinets in our own shop. When trees come down on your property during a project, we mill them into the floors, beams, and counters of the home, so a part of the land becomes a part of the structure. Families who need to live at home while we work get temporary kitchens, dust walls, and negative-pressure containment. You also get a JobTread login with daily field reports, photos, the live budget, and every file, plus a weekly walk-through with our team on site. Our kitchens come in within 5 percent of the original budget, and we hand over the keys when we said we would. We are Andersen Certified and Licensed in Pennsylvania (PA015145), and we bring that standard to every project the same way we have brought it to Chester County for forty years.
Our Unionville Home Building 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 Unionville
McComsey Builders is rooted in Chester County, and East Marlborough Township has been part of our territory since the early years. Bob McComsey Sr. founded the company in Parkesburg in 1986, and his sons Bob and Mike run it today, keeping the same family name on every project and the same hands-on approach that has served this part of Pennsylvania for two generations.
The ground around Unionville, from the wide fields near Natural Lands’ ChesLen Preserve to the wooded ravines along The Laurels Preserve, is some of the most naturally beautiful building country in Chester County. Estates here carry history in their stone walls and timber frames, and new construction has to earn its place beside them. We have built and renovated homes in this part of the county long enough to understand what the setting demands: materials that age well, structural choices that respect the existing land, and a process that keeps the homeowner informed every step of the way. The McComsey name is on every job, and in this community that has come to mean something.
Unionville Home Building FAQs
Does McComsey Builders build custom homes in Unionville, PA?
Yes. Custom home building is our flagship work, and the estate lots and open properties around Unionville are well suited to it. We evaluate buildability early, help source the right architect, and stay with you from the first site visit to the day we hand over the keys. See how we approach new construction on our custom home building page.
Can you build a horse barn or equestrian facility in Unionville?
Yes. Accessory structures are a significant part of our work in the Unionville area, where equestrian properties and larger lots are common. We build horse barns, car barns, pool houses, and party barns with the same craft we bring to a main house. You can learn more on our accessory structures page.
Can McComsey renovate an older stone farmhouse in Unionville?
Yes, and it is some of our best work. Historic stone homes in East Marlborough Township require a builder who can work with thick walls, original materials, and the character that makes these properties worth saving. We have restored and expanded historic homes across Chester County, integrating modern systems without losing what the original builders put into the structure.
Will my family be able to stay at home during a Unionville renovation?
In most cases, yes. We build temporary kitchens, dust walls, and negative-pressure containment so the work does not take over the way you live. We plan the phasing with you before anything starts, and we walk the site with you each week so you always know what is coming next.
How do we know the project will stay on budget?
Every McComsey client gets a JobTread login with daily field reports, photos, and the live budget, so you can see exactly where the project stands at any point. Our kitchens come in within 5 percent of the original budget, and we hand over the keys when we said we would. Transparency is part of how we have built our reputation in Chester County over forty years.
What other services does McComsey offer in the Unionville area?
