Exterior Painting in St. Louis

Exterior paint does more than make your house look good. It is the first line of defense against water, UV rays, temperature swings, and insects. When exterior paint fails, moisture gets into the wood and the damage starts. Rot, mold, peeling, and repair bills that cost far more than the paint job would have.

At OnDemand Painters, we treat exterior painting as a protection job first and a cosmetic job second. Here is how we do it.

Full exterior inspection

Every exterior project starts with a thorough inspection. We walk the entire house and check the condition of every surface. Siding, trim, fascia, soffits, window frames, and doors. We look for peeling paint, cracked caulk, rotted wood, mildew, and any spots where water might be getting in. You get an honest assessment of what needs repair before any paint goes on.

Prep, repair, and priming

Prep is everything on an exterior job. We pressure wash the entire house to remove dirt, mildew, chalky old paint, and cobwebs. Loose and peeling paint gets scraped by hand. Rough spots are sanded smooth. Rotted wood gets replaced or filled with epoxy filler. All gaps around windows, doors, and trim get fresh caulk to seal out moisture.

After prep, we prime any bare wood, repaired areas, and problem spots. Primer gives the topcoat something to grab onto and blocks stains from bleeding through. On surfaces in good shape, spot priming is usually enough. On heavily weathered or bare surfaces, we prime everything.

Siding types and paint selection

We work with every common siding type. Wood lap siding, cedar shakes, vinyl, brick, stucco, fiber cement (Hardie board), and aluminum all have different requirements. The paint type, application method, and prep all change depending on what your house is made of. We know the differences and adjust accordingly.

For paint, we use Sherwin-Williams and Benjamin Moore exterior products. These paints are formulated to handle UV exposure, temperature swings, rain, and humidity. We select the right sheen and formula for your siding type and your local climate. Flat and satin sheens work well on siding. Semi-gloss goes on trim and doors for durability and a clean look.

Application and access

Application depends on the surface. We brush trim work and detail areas. We roll or spray large siding surfaces for even coverage and efficiency. Every surface gets two coats minimum. We pay close attention to areas that take the most weather. South-facing walls, trim around windows, and anywhere water runs.

Ladder and scaffold work is part of what we do. Two-story and three-story homes need safe access, and we have the equipment and experience to handle it. You do not need to worry about liability. Our crew is fully insured and trained for height work.

Timeline and guarantee

Most exterior paint jobs take three to seven days depending on the size of the home, amount of prep, and weather. We need dry conditions and temperatures above 50 degrees for proper paint application and curing. We watch the forecast closely and plan around rain.

We have been painting exteriors for over 20 years. Our crew works for us directly. All crews vetted and trained to the same standards. You get a written guarantee on the work, and we stand behind it. A quality exterior paint job should last seven to ten years or more, depending on your climate and the condition of the surfaces when we start.
