Exterior Painting in Johnstown, CO

Exterior painting in Johnstown is shaped by how fast the town has grown around the I-25 and US 34 interchange. Most homes we look at here are newer, garage-forward subdivision houses on open ground, and a smaller share sit in the older town to the east, where the siding and the prep are a different story.

Garage doors set the tone on newer Johnstown homes

On a lot of the houses built near the interstate in the last couple of decades, the garage door is the biggest single painted surface you see from the street. Two- and three-car steel doors face south or west on half the lots, and they fade, chalk and take hail dents before anything else on the front of the house. A tired garage door makes fresh siding look unfinished.

We clean steel doors, scuff the glossy factory finish so the new coat can grip, spot-prime any bare or rusted metal, and roll the panels in a direction that follows the embossed grain. Dents stay dents; paint doesn't fill them. If a door has been badly hailed, it's worth asking whether replacement is on the table before we paint it. Trim, doors and fascia details are covered on our trim and fascia painting page.

New subdivision or original town: two different jobs

Newer subdivision homesOlder homes in the original town
Typical sidingEngineered wood or fiber cement lap, stone accentsWood lap siding, some aluminum or steel siding added later
Main prepWashing chalk, recaulking joints, edge sealingScraping, wood repair, priming bare wood
Lead-safe practicesNot required by the EPA rule for homes built in 1978 or laterAssumed for pre-1978 paint unless testing shows otherwise
Color approvalOften through an HOAUsually up to the owner
What fails firstSouth and west walls, garage door, caulk jointsSills, lower siding courses, porch and step edges

If you're in a subdivision with an HOA, plan the color submittal before booking a start date. Older homes in the core need a longer walk-through, because the repair list sets the price more than the square footage does.

Newer streets also have very little shade yet. Young trees don't protect anything, so every wall gets its full share of sun at nearly 5,000 feet, and the chalk that builds up on fiber cement and engineered wood has to be washed off completely before primer or paint will hold. Rub a dark cloth on your south wall; if it comes away colored, that's the chalk we're talking about.

Hail on open ground

Johnstown sits on open plains east of Loveland, and summer storms that build over the foothills in the afternoon often strengthen as they move out over the plains. Hail here does a predictable set of things to a house: dents in aluminum gutters, downspouts and garage doors, chips and spatter marks on the windward siding, and cracked caulk or punctures in thinner siding boards. Window screens and vinyl window frames take hits too.

How the season runs this far east

April and early May bring warm afternoons along with cold nights, heavy wet snow and gusty days. Every paint has a minimum air and surface temperature on its product data sheet, and we go by that, not the afternoon high. Summer is the reliable stretch, with work starting on the east and north sides in the morning and following the shade. Afternoon thunderstorms mean we watch the radar and stop exposed coats in time to dry. Fall is often calm and dry here, though nights cool fast after the equinox and the working day shrinks.

Before you request an estimate

Walk around the house once with the garage door closed and note dents, rust spots, swollen siding edges and gaps at window trim. Check whether your HOA needs a color form. Find out if any hail repairs are still pending. Johnstown neighbors Milliken to the east and Loveland to the west, so our Milliken exterior painting page may also be relevant if you're near that side of town. Then request an estimate and we'll go over the house in person.

FAQ

Johnstown exterior painting questions

Can a hail-dented garage door be painted?

Yes, but painting won't remove the dents. A clean, scuffed and properly primed steel door takes paint well, and a fresh color can make minor dents less noticeable in flat light. Doors with deep or widespread dents may be better candidates for replacement, especially if an insurance claim covers it. Decide that before we include the door in the paint scope.

Should my garage door match the trim or the body?

On newer Johnstown homes where the garage door dominates the front, matching it to the body color usually makes it recede and lets the front door stand out. A contrasting garage door can work on homes with strong trim lines or stone accents. Check your HOA guidelines first, since some specify garage door colors.

Do older homes in Johnstown need lead-safe painting?

If the house was built before 1978, the older paint layers may contain lead. Paid work that disturbs that paint falls under the EPA's Renovation, Repair and Painting rule, which calls for containment, wet methods and thorough cleanup. A lead test can settle the question, but without one we treat pre-1978 paint as if lead is present.

Does aluminum or steel siding need special prep?

It needs washing to remove chalk, scuffing where the old finish is glossy, and a primer suited to metal wherever bare spots or rust show. Once prepped, metal siding takes exterior acrylic paint well. Old hail dents stay visible under new paint, and a low-sheen finish shows them less than a glossy one.
