When we handle concrete sealing in Weldon Spring, MO, it comes down to three things: protecting your plants and property, cleaning with the right method, and walking the job with you at the end.
The right method for the job
Is it time for concrete sealing?
- Water soaks in instead of beading
- Stamped concrete looks faded and dull
- Surface flaking or spalling has started
- Stains soak in quickly
Why it gets dirty
- Old sealer worn away by sun and traffic
- Freeze-thaw cycles and deicing salts
- Unsealed concrete absorbing oil and water
Safe steps for homeowners
- Do the water test: sprinkle water and see if it darkens the concrete quickly
- Keep traffic off a newly sealed surface for the time on the label
- Avoid deicers that contain ammonium nitrate or ammonium sulfate

Do you use high pressure for concrete sealing?
Concrete Sealing is usually done with clean, then seal, with the pressure adjusted for each surface. Delicate surfaces nearby, such as siding, windows and plants, are protected or cleaned with lower pressure.
Is concrete sealing safe for my plants and pets?
We pre-wet plants and lawns, keep cleaning solutions diluted to what the surface needs, and rinse landscaping again when we finish. Keep pets and children inside until surfaces are rinsed and dry.
How often should I schedule concrete sealing?
Every 2-5 years, depending on the sealer. Shade, nearby trees, humidity and heavy traffic mean more frequent cleaning; sunny, dry spots can go longer. Our free cleaning frequency tool gives a recommendation for your climate.
What if it rains on the day?
Light rain doesn't stop most washing, but heavy rain, high wind, lightning and freezing temperatures do, and sealers and stains need dry weather to cure. If the weather isn't right, we reschedule at no charge. Our work is backed by a satisfaction guarantee.
