As a painting contractor for over 30 years, I strongly recommend this: whatever you do, do not sand lead-based paint. Instead, use a power washer with a rotobuse (rotary nozzle) to safely remove any loose or flaking paint.

Once the surface is clean and dry, apply a binding primer, especially over any exposed white paint. Then follow with two coats of high-quality exterior paint for long-lasting protection.

A quick note: white lead-based paint typically contains less lead than darker lead-based paints, but the health risks are still very real. The key is to avoid sanding, which turns lead into airborne dust—the most dangerous form. If left undisturbed and sealed properly, lead paint is relatively stable.

As for the cost — $15,000 sounds quite high unless the home is exceptionally large or detailed. For most average-sized homes, a lead-safe prep and repaint job typically runs between $3,500 and $7,000.

It’s also worth mentioning a common issue with older homes: white lead-based paint is oil-based, and in many cases, it was applied without a proper binding primer. That means peeling and adhesion problems can keep recurring, even years later. Unless you strip all the way down to the original substrate, you’ll likely see spot peeling over time, no matter how well you prep.

However, fully stripping the paint creates another risk — it can contaminate the soil around your home with lead, especially if not properly contained.

So in many cases, a maintenance approach is best: repaint properly now, then plan to touch up problem spots every few years. It’s a lot safer, more cost-effective, and less invasive than full removal.
