1. Old-Growth Wood is More Durable Than Modern Lumber

Many historic homes were built using old-growth wood—a dense, slow-growing timber that resists rot, pests, and warping. If your home has original hardwood floors, beams, or trim, you’re working with superior materials that often outlast modern replacements.

2. Horsehair Plaster is Stronger Than Drywall

Before drywall became standard, builders used horsehair-reinforced plaster, which added strength and flexibility to walls. Unlike drywall, this material helps regulate humidity and improves soundproofing—one reason why older homes feel quieter.

3. Your Home May Have Hidden Rooms or Secret Spaces

Many historic homes have hidden storage nooks, root cellars, or even secret passageways. Some were built for food preservation, while others had a more mysterious past—such as acting as part of the Underground Railroad.

4. Wavy Glass Windows are a Sign of True Age

If your home’s window glass looks wavy or uneven, that’s a sign it’s handmade pre-1900 glass. Modern glass is machine-made and uniform, so preserving original windows maintains both authenticity and value.

5. Knob-and-Tube Wiring Isn’t Always Dangerous

Homes built before 1940 often feature knob-and-tube wiring, an early electrical system. While outdated, it’s not inherently dangerous unless modified incorrectly. However, since it lacks grounding wires, it’s best to have it inspected by a historic home electrician.

6. Historic Brick Walls Were Designed to Breathe

Unlike modern construction that relies on vapor barriers, old brick homes absorb and release moisture naturally. Sealing old bricks with modern materials can trap moisture and cause damage. Use breathable lime-based mortar instead of cement when making repairs

7. Original Paint Might Be Milk Paint

Many historic homes were painted with milk paint, a non-toxic formula made from milk protein, lime, and natural pigments. It resists peeling and allows wood to breathe—something modern paints don’t do.

8. Fireplaces Were Early Ventilation System

Older homes didn’t just use fireplaces for heat—they also served as early air circulation systems, helping regulate indoor air quality by drawing in fresh air and expelling smoke, dust, and moisture.
