Your Home's Possibilities:

Make Your Dreams Come True

Custom Home Construction

Across the Greater Philadelphia Area, Harth Builders is well-known for our award-winning remodeling services, but what many homeowners may not realize is that we build custom homes, as well.

Custom Homes
Whether you are already working with an architect, or would like us to provide the complete spectrum of construction services, Harth Builders has the design-build expertise to create the ideal custom home for you.
Custom Modular Homes
Harth Builders recently announced a collaboration with Westchester Modular Homes (WMH) to build custom single-family and multi-family homes. Known for their high-quality construction and rapid turnaround time, WMH has been manufacturing modular homes since 1986. By offering WMH products to our clients, Harth Builders enhances their ability to deliver luxury custom homes for clients quickly and efficiently.

Whereas homes that are custom built on-site often experience weather-related production delays, modular custom homes are constructed by experienced craftsmen indoors in a climate-controlled environment. One of the benefits of this arrangement is that work can be scheduled and performed more easily. Constructing custom homes in a warehouse also provides greater security for building materials, which yields cost-savings for homeowners as it reduces waste and shrinkage in the process.

What is Good Design?

Universal Design

Universal design means building products and environments to make them accessible to all people, regardless of age, disability or additional factors. We at Harth are dedicated to making sure your home fits your needs, no matter what those needs are. Our goal is for our clients to be able to live comfortably and feel safe in their spaces.

Designed for your lifestyle and budget

Exterior Renovations

If you want to make your home as beautiful on the outside as it is on the inside, Harth Builders is the remodeling contractor for you. Our expert team of certified remodeling professionals will provide you with the design, planning, and project execution for an exceptional exterior home renovation.

Curb Appeal
Exterior renovations that improve the look of your home from the street are considered curb appeal enhancements. These home improvements make you feel better every time you walk up to your door. As an added benefit, they can also improve resale value. Whether you would like to add a new front entrance, update an existing portico, or add a covered porch, contact Harth Builders for assistance.
Outdoor Living Spaces
With the help of our talented team of designers and craftsmen, Harth Builders will create an outdoor retreat where your family and friends can relax and unwind throughout the year. Whether you are looking for a terraced composite wood deck, or a beautifully hardscaped patio with seating vignettes, a built-in barbeque grill, and firepit, Harth Builders will create the ideal outdoor living area for your lifestyle and budget.
Stucco Repair
If you live in a stucco home built in the last 20 years, you may need to have your home assessed for necessary repairs. Sources, such as our local CBS affiliate, report that there has been widespread stucco failures in homes across our area. You might consider replacing your stucco with various materials such as cement board siding, acrylic stucco, or a newer PVC siding product. Removing stucco can often lead to additional opportunities such as replacing existing, and often dated, arched windows and doors.

Window and Door Replacements
Our full-service remodeling firm specializes in all aspects of home renovation — including windows and doors.
Energy Efficiency Renovations
By testing for power consumption, temperature variances, air leaks and more, Harth Builders can determine the best solutions for improving your home’s overall energy performance and lowering your cost of living. The first step is to conduct a blower door test. Blower door tests, which start at less than $900, identify the ``leakiness`` of your home. The data we collect from this test creates a baseline of energy efficiency and enables Harth Builders to provide a comprehensive strategy with multiple options for improving the energy efficiency of your home.
Room Refresh
Several of your spaces may function adequately but just need a little love. Our Design in a Day program offers you the same dedicated design team and quality construction you trust without the time commitment of multiple meetings. Simple rooms/areas to refresh can include: bathrooms, kitchens, decks, and lower levels!
