Concrete Spring Cleaning
Last Updated: 05/11/2026As the spring season approaches, it is essential to start thinking about how to care for your residential concrete. It's easy for homeowners to overlook concrete care during spring maintenance. However, whether you have a concrete driveway, patio, fire feature, or other outdoor spaces, the winter season likely took its toll. Therefore, it's crucial to maintain your concrete each year to avoid severe damage.
Performing concrete spring maintenance is vital due to the rise and fall in temperature during winter, along with rain and snow, which can wear and tear concrete. Additionally, the accumulation of snow and ice has the potential to penetrate pockmarks and small cracks on your concrete surface. Ice is an element that causes damage because of its natural expansion and contraction on the concrete surface. Thus, it is a perfect time to inspect concrete surfaces for any damage such as gaps, cracks, and crumbling during the spring season.
If minor problems are unattended, they can worsen and cause concrete to experience severe distress, leading to extensive repairs and unnecessary costs. Therefore, regular maintenance each spring that includes the repairs of any damage or potential issues is well worth it! Moreover, following a simple maintenance regimen prolongs the life of your concrete surfaces.
To start the spring cleaning project, clean all outdoor concrete surfaces with a soft broom to sweep away any debris such as leaves and branches. Afterward, closely inspect the condition of the concrete to look for any alterations, even if they seem insignificant. Be sure to check for signs of algae growth, stains, mildew, and moss that can alter the appearance of your concrete and create dangerous slippery surfaces.
After a thorough cleaning, you'll be ready to check the surface for its integrity. You may start to notice cracks or other damage. Check for areas where water pools after the rain or weed growth, indicating structural damage. The best practice is to address any damage, even if minor, to avoid extensive repairs in the future.
Leaving cracks and other damage unattended can lead to tripping hazards and lowers the curb appeal of your home. It is best to do repairs sooner rather than later, so keep a vigilant eye on your driveway this spring! If you're not the DIY type, it's best to leave the repairs to professional concrete experts that have the experience, knowledge, and tools to easily do the job.

Frequently asked questions
When should I do concrete spring cleaning in Seattle?
Mid-March through April — once the wettest months are behind and surface temperatures stay above 50°F. Cleaning before sealer reapplication is best done when the surface can dry fully within 48 hours.
What products work best for cleaning concrete in the PNW?
Mild alkaline detergent for general dirt and organic stains. Concrete-specific degreasers for oil and grease. Diluted oxygen bleach (sodium percarbonate) for moss and algae — safer than chlorine bleach and won't damage adjacent plants.
How often should I reseal concrete in Seattle?
Penetrating sealers (silane or siloxane): reapply every 3–5 years. Acrylic topcoats: reapply every 2–3 years due to UV breakdown. Driveways and patios with heavy use or shade may need more frequent resealing.
How do I remove moss and algae safely?
Stiff brush or low-pressure rinse to clear loose growth, apply oxygen bleach or commercial moss treatment per label, let dwell, rinse, let dry fully, then seal. Address the drainage and shade conditions that allowed the growth in the first place.
Is pressure washing safe for concrete?
Yes when done correctly: 1,500–2,500 PSI with a 25–40 degree spray tip, kept moving and 12–18 inches from the surface. Higher pressure or holding the nozzle close can erode surface paste and expose aggregate prematurely.
