The secret to paver cleaning & sealing is using the right method, not the most pressure. In New Hampshire, we match the cleaner and pressure to the surface so it comes out clean without damage.
How we clean it
Is it time for paver cleaning & sealing?
- Weeds and moss growing in the joints
- Joint sand washed out or full of ant hills
- Faded, dull pavers
- White haze (efflorescence) on the surface
- Pavers shifting at the edges
Why it gets dirty
- Rain and washing that remove joint sand over time
- Shade and organic debris in the joints
- Salts rising out of the pavers and base
- UV fading the color
Safe steps for homeowners
- Pull weeds before they root deeply
- Top up joint sand where it's low
- Keep downspouts from pouring onto pavers

- Blasting out joint sand and loosening pavers
- Sealing over efflorescence or damp pavers, which traps a white haze
- Using the wrong sealer, which can turn cloudy or slippery

Do you use high pressure for paver cleaning & sealing?
Paver Cleaning & Sealing is usually done with pressure wash, re-sand and 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 paver cleaning & 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 paver cleaning & sealing?
Clean every 1-2 years, reseal every 2-4 years. 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.
