How to Protect Historic Home Details During an Exterior Paint Project

Historic homes throughout Philadelphia and the Main Line were built to stand out. From hand-milled trim and detailed cornices to original shutters, windows, and stonework, many of the features that give these homes their character have survived for generations.

An exterior paint project should help preserve those details without damaging them in the process. Historic home painting is different from repainting a newer property. Preparation often needs to be more selective, repairs more precise, and paint application more controlled. Homeowners may also need to consider lead-safe work practices or local historic preservation requirements before work begins.

Whether you own a Colonial Revival in Wayne, a Tudor in Bryn Mawr, or a Classic Brownstone in Center City, knowing what careful historic painting looks like can help you protect both its appearance and its architectural integrity.

Can You Paint a Historic Home?

Yes. In fact, historic home painting can be an important part of protecting wood from weather and deterioration.

Historic homes may contain original wood siding, decorative moldings, window components, and other materials that have already been through many painting cycles. Aggressive scraping, sanding, washing, or unnecessary stripping can remove historic material along with failing paint.

Instead, a painter experienced in preservation evaluates the home and removes only as much paint as necessary to create a sound surface. Areas where the existing coating remains well adhered may need little intervention, while badly deteriorated sections require more extensive preparation.

Know Whether Historic Preservation Rules Apply to Your Property

Not every old home is legally designated as historic, but homeowners with designated properties should determine whether exterior work requires review before making changes.

In Lower Merion Township, for example, designated historic properties may fall under Historical Architectural Review Board (HARB) requirements for exterior alterations. Within Philadelphia, properties on the Philadelphia Register of Historic Places are governed by the Philadelphia Historical Commission.

Routine maintenance and repainting may be treated differently from altering architectural elements, changing masonry coatings, or replacing features such as shutters, cornices, railings, and doorways. Before making significant changes to a designated property, confirm what approvals apply. It is much easier to incorporate preservation requirements into the project from the beginning than to discover them after work is underway.

Start With the Condition of the Home, Not the Paint Color

An experienced painter will carefully evaluate what is happening beneath the existing finish. Peeling and blistering might not be indicative of old paint. The culprit could be moisture entering around windows, gutters, roof lines, or deteriorated joints. Painting over the symptoms without correcting the underlying problem can leave you with the same peeling paint again in a few months.

Before a historic home painting project, a careful inspection may identify:

• Loose, cracked, or blistered coatings
• Soft or deteriorated wood around trim, sills, and other details
• Open joints that allow water intrusion
• Moisture problems that need to be corrected before painting
• Decorative features that require particularly careful preparation
• Previous repairs or coatings that may affect the new paint system

Documenting these conditions before work begins also creates a record of which elements are original and which need repair work.

Repair Original Details Whenever Practical

Localized deterioration can sometimes be repaired, while severely damaged portions can be spliced with matching material. Preserving an original component is especially valuable when dealing with custom profiles and craftsmanship that may be difficult to reproduce accurately today.

Throughout the Main Line are homes ranging from Colonial and Georgian Revival to Tudor Revival and Queen Anne. Decorative trim often contributes directly to the proportions and architectural identity of these houses. When replacement truly is necessary, the new work should reproduce the dimensions and profile of the original as closely as possible.

Protect Historic Woodwork With Gentle Surface Preparation

Years of heavy paint buildup can soften crisp edges, grooves, brackets, moldings, and other profiles. Aggressive preparation like excessive sanding or scraping can also make these features less crisp and distinct. To avoid this, historic home painting project preparation should begin with the gentlest method of removing loose or failing material. Depending on the condition and detail involved, that can mean controlled hand scraping, careful sanding, or specialized removal techniques in intricate areas.

Cleaning should also be done with care. High-pressure washing can damage older wood or force water behind siding and trim. Historic materials benefit from a more controlled approach that cleans the surface without saturating or eroding it.

Lead-Safe Practices for Older Philadelphia-Area Homes

Federal Renovation, Repair and Painting (RRP) requirements apply to contractors performing qualifying work that disturbs lead-based paint in pre-1978 homes. Lead-safe practices can include containing the work area, controlling paint debris and dust, using appropriate cleanup procedures, and avoiding removal methods that create unnecessary lead hazards.

This is particularly relevant for the Main Line, where much of the region’s historic housing stock predates 1978. If your home falls into that category, ask your prospective painters how they handle lead-safe preparation and containment. Protecting historic architecture and protecting the people and property around it should be part of the same process.

What Are the Three Paint Colors That Will Never Go Out of Style?

Historic home painting doesn’t have to mean that every home must be painted exactly as it looked a century ago, but color choices should work with the architecture rather than compete with it. Start by looking at the home’s style, existing materials, neighboring architecture, and which details you want to emphasize. Historic photographs, local records, or examples of similar homes can also provide clues if you’re interested in a period-appropriate palette.

The relationship between colors is often just as important as the individual shades. Body, trim, sash, shutters, doors, and other details can be coordinated to make architectural features more visible without making the exterior feel overly busy.

While paint trends change, white, black, and deep green are three exterior colors that have remained dependable choices for historic homes, particularly throughout Philadelphia’s Main Line.

• White is a classic choice for exterior trim because it creates contrast while highlighting original architectural details. On traditional stone homes, crisp white trim can draw attention to windows, cornices, and other features without competing with the natural character of the stone. It also pairs naturally with brick, where white trim and siding remain popular choices.
• Black is equally enduring as an accent color. Black shutters and front doors are a classic combination on Main Line stone homes, and black shutters also provide strong contrast against brick and white trim.
• Deep green offers a slightly softer alternative while still feeling traditional. Light beige is often recommended for stucco homes paired with deep green shutters and a matching front door.
• Deep blues have also become popular for shutters and other exterior accents, particularly on brick homes.

Protect the Rest of the Property, Too

Most properties have mature trees, shrubs, gardens, stone walkways, patios, and other established landscape elements immediately surrounding the work area that need to be protected.

Before historic home painting begins, landscaping should be protected without damaging the plants themselves. Shrubs touching the house may need to be gently tied back, while breathable coverings can protect foliage from paint debris and splatter without trapping excessive heat. Ladders, equipment, and foot traffic should also be positioned carefully around mature trees and planting beds to minimize damage to roots and soil.
