FAQs About Historic Home Renovating
What qualifies as a historic home?
Generally, a home is considered historic if it’s 50 years or older and retains key architectural features from its original era. Some properties are officially designated as historic by local, state, or national preservation groups. These designations often come with increased regulation during renovation.
Do I need approval to renovate a historic home?
If your home is in a designated historic district or on a preservation registry, yes. Local boards may review and approve any changes to your home’s exterior or structure. We’re experienced in navigating these requirements in both Delaware and Pennsylvania.
How long does a historic home renovation usually take?
It depends on the scope and condition of the home. Smaller projects may take a few months for construction, while full-home renovations can span six months or more, especially when dealing with structural issues or preservation reviews.
How much does it cost to renovate a historic home?
Costs vary widely depending on the size, age, and condition of the home, as well as the scope of work. Restoring original details, sourcing period-appropriate materials, and working within preservation guidelines can make historic renovations more complex than standard remodels. Smaller projects may start around $50,000, while whole-home renovations can range from $150,000 to $500,000 or more. We provide detailed, accurate cost estimates upfront so you know exactly what to expect.

We highly recommend them."

“We were very pleased with Frank Bromwell's company and their remodel of our bathroom. We live in a very old Victorian house in the City and they were very experienced with old city homes. His crew were great, friendly and very professional. Highly recommended.”
