Preparing Your Des Moines Home for an Exterior Paint Job

An exterior paint job is one of the best investments you can make in your Des Moines home. It boosts curb appeal, protects against the elements, and can even increase property value. But the difference between a paint job that lasts three years and one that lasts ten often comes down to what happens before the first brush stroke. In Des Moines, where we face everything from humid summers to freezing winters and occasional spring storms, proper preparation is especially critical. Below are practical, locally relevant steps to get your home ready for a long-lasting exterior paint job.

Assessing the Condition of Your Home's Exterior

Before you even think about paint, take a slow, careful walk around your house. In Des Moines, the freeze-thaw cycle in winter can cause paint to blister and peel, especially on south-facing walls that get afternoon sun. Look for areas where old paint is cracking, chalking, or bubbling. Also check for signs of wood rot, particularly around window sills, door frames, and the base of porch columns. Spring rains and summer humidity can lead to mildew growth on shaded sides of the house. If you see dark spots, you'll need to treat those with a mildewcide solution before painting.

Pay close attention to caulking around windows and doors. Des Moines wind can drive moisture into gaps, and over time that leads to more damage. Any deteriorated caulk should be removed and replaced. Addressing these issues now will save you from having to do touch-ups every year.

Cleaning and Surface Preparation

A clean surface is essential for paint adhesion. In Des Moines, dirt and pollen from the many trees and gardens can accumulate on siding. A thorough power wash is often the best first step. However, be careful with wood siding if you have an older home in the Sherman Hill or Kingman Place neighborhoods. Too much pressure can damage the wood or force water behind the siding. If you're not comfortable with a pressure washer, a garden hose and a long-handled brush with a mild detergent can work well.

After washing, let the surface dry completely. In our humid summers, that might take a full day or more. Then, scrape off all loose paint with a putty knife or a wire brush. Sand rough edges to feather them into the surrounding paint. For any bare wood, apply a high-quality exterior primer. This step is not skippable in Des Moines because unpainted wood can absorb moisture quickly during a summer shower.

Useful tools to have on hand:

• A sturdy scraper (curved ones work well for siding)
• Sandpaper or a sanding block (medium grit)
• A putty knife for applying wood filler or caulk
• A caulk gun with exterior-grade caulk
• A drop cloth or plastic sheeting to protect the ground

Protecting Your Landscaping and Property

Des Moines homeowners take pride in their yards. Before painting begins, you need to protect your plants, patio furniture, and anything else near the house. Move potted plants, grills, and lawn ornaments away from the work area. Trim back any bushes or shrubs that are touching the siding. When painters use ladders or scaffolds, they can crush branches, so it's better to cut them back a few inches.

Cover delicate plants with lightweight plastic sheeting or old sheets. Avoid using heavy tarps that can crush them. For flower beds, you can use a simple "paint guard" by laying down a tarp and holding it in place with landscape staples. Also, remove or cover light fixtures, house numbers, and mailboxes. If you have window shutters, it's often easier to remove them, paint them separately, and then reattach them. This prevents drips and gives a cleaner finish.

Don't forget about the driveway and walkways. Paint drips on concrete are hard to remove. Lay down canvas drop cloths, not plastic, because plastic can get slippery when wet and can cause paint to pool. Canvas is more breathable and stays in place better on a windy Des Moines day.

Timing and Weather Considerations

In Des Moines, the best times for exterior painting are late spring (May into early June) and early fall (September into October). During these windows, temperatures are typically between 50 and 85 degrees Fahrenheit, and humidity is lower. Summer heat can cause paint to dry too quickly, leading to brush marks and poor adhesion. Winter is obviously out of the question for most exterior work.

Always check the weather forecast for a stretch of at least two to three consecutive dry days. If rain is expected within 24 hours after painting, the paint may not cure properly. Also, avoid painting when the wind is gusting above 15 mph, which happens often in our open plains. Wind can blow dust, pollen, and leaves onto the wet paint, ruining the finish. Early morning or late afternoon are often the calmest times of day.

If you're painting a surface that has been in direct sunlight all afternoon, wait until the sun moves off that side of the house. Painting a hot surface can cause the paint to bubble. A little patience with timing goes a long way toward a professional-looking result.
