TL;DR: Roughly seven in ten Denver homes were built before 1978, the year lead-based residential paint was banned — and in historic neighborhoods like Capitol Hill and Baker, virtually every home carries older paint layers that should be presumed to contain lead until tested. That doesn’t mean these homes are dangerous to live in or impossible to repaint. It means repainting them properly requires EPA lead-safe (RRP) work practices: containment, dust control, and careful cleanup, rather than dry-scraping and sanding old paint into the air your family breathes. Here’s what every owner of an older Denver home should know before the next paint job.
If you own a Victorian in Capitol Hill or one of the colorful painted ladies in the Baker historic district, you own a home that was almost certainly painted with lead-based paint at some point in its life. That’s not a scare line — it’s just arithmetic. Lead paint was prized for durability and used widely in American homes for decades until the federal government banned it for residential use in 1978. The City of Denver estimates that around 70 percent of the city’s housing stock predates that ban. In the neighborhoods where our crews spend the most time on ladders — the mansions and mansion-block apartments of Capitol Hill, the Victorians off South Broadway in Baker, the Denver Squares around Wash Park — the housing stock is not just pre-1978 but often pre-1930, which means multiple layers of decades of paint, and the older the layer, the higher the likely lead content.
The good news most articles skip
Intact lead paint under sound modern layers is generally not a hazard. Lead paint becomes dangerous when it deteriorates or gets disturbed — when it chips, peels, chalks, or gets dry-scraped and sanded into dust. Lead dust is the primary exposure route, and it’s especially serious for young children. Friction surfaces are the classic troublemakers: original double-hung windows grinding lead-painted sash against lead-painted jamb every time they open, doors rubbing their frames, stair treads and porch floors wearing through. So the goal for owners of older homes isn’t panic; it’s management. Keep paint intact, address deterioration promptly, and when it’s time to repaint, make sure whoever does the work follows lead-safe practices rather than blasting a century of paint history into your yard and living room.
What the law actually requires
Since 2010, the EPA’s Renovation, Repair, and Painting (RRP) rule has required that contractors disturbing paint in pre-1978 homes — more than six square feet per room inside, or more than twenty square feet outside — be trained and certified in lead-safe work practices, and follow specific procedures for containment, dust minimization, and cleanup. This isn’t optional, and it isn’t a premium add-on; it’s federal law. Yet ask around Capitol Hill after any summer and you’ll hear about crews dry-sanding hundred-year-old trim with no plastic down and no signage in sight. When you’re vetting painters for an older home, asking directly about RRP compliance is one of the fastest ways to separate professionals from the rest. Our team follows EPA RRP lead-safe work practices on pre-1978 homes as standard procedure — you can read more about our lead-safe painting approach here.
What lead-safe work actually looks like on a Baker Victorian
Homeowners are sometimes surprised by how visible the difference is. On a lead-safe exterior job, you’ll see heavy plastic sheeting on the ground extending well out from the wall being worked, taped tight at the foundation; you’ll see wet-scraping and wet-sanding instead of clouds of dry dust; you’ll see HEPA vacuums instead of leaf blowers at cleanup; and you won’t see power-sanding old paint without shrouded, HEPA-attached equipment. Inside, work areas get sealed with plastic, floors get covered, and the cleanup finishes with HEPA vacuuming and wet-wiping rather than a broom. Last season our crew repainted the front elevation of a c. 1890 Victorian in Baker where the previous paint had alligatored down to early layers. The scraping phase took days under containment — wet methods, constant cleanup, every chip landing on plastic and leaving in sealed bags. It’s slower. It’s also the only responsible way to do it, and the finished front porch — deep body color, crisp cream spindles — will protect those hundred-year-old boards for another decade or more. Slow down now so the results last for years; on pre-1978 homes, that family rule of ours carries extra weight.
Practical guidance for Capitol Hill and Baker owners
A few honest recommendations from crews that work on this housing stock constantly. First, if your home predates 1978, assume older layers contain lead until a test says otherwise; inexpensive testing is available and worth it before major work. Second, prioritize friction surfaces and failing paint — peeling window sash and porch floors matter far more than intact walls. Third, if you’re doing any DIY prep on an older home, skip the dry sanding entirely: mist surfaces before scraping, and never use a heat gun hot enough to vaporize old paint. Fourth, when hiring out the work, ask every bidder how they’ll contain and clean up dust on a pre-1978 home, and listen for a specific answer rather than a shrug. A painter who can’t describe containment has never done it.
None of this should discourage you from repainting an older home — quite the opposite. A sound, professionally applied paint system is exactly what keeps old lead layers safely encapsulated and your original woodwork protected from Denver’s sun and freeze-thaw cycles. The Victorians of Baker and the grand homes of Capitol Hill have survived a century of Colorado weather precisely because generations of owners kept paint on them. Our exterior painting team and interior crews treat these houses with the respect that age demands — and with the containment that federal law and common sense both require.
