Why paver patios need more than just cleaning
Paver patios are designed to flex slightly with NH's freeze-thaw cycles — and the joint sand between pavers is what keeps everything stable and in alignment. Over time, rain washes sand out, weeds and ants work their way into the gaps, and the structural integrity of the surface starts to break down. A patio that was solid when installed can become uneven, wobbly, and weed-choked within a few years without proper maintenance.
Cleaning the surface alone doesn't fix depleted joints. Resanding after a thorough clean restores the stability and appearance of the patio — and using polymeric sand instead of regular sand means the joints stay locked, weed-resistant, and intact for years instead of washing out the next spring.
Our patio cleaning & resanding process
- Thorough pressure washing to remove algae, mold, dirt, and biological staining from paver surfaces
- Removal of weeds and organic material from joints
- Allow surface to dry completely
- Application of polymeric sand to all joints, swept and compacted in layers
- Light misting to activate the polymeric binder
- Final inspection to ensure full joint coverage
Polymeric sand vs. regular sand
Regular sand is the original material used in most paver installations — it's inexpensive but washes out easily, compacts and settles over time, and provides no resistance to weeds or insects. Polymeric sand contains a binding agent that, once activated with water, sets firm and bonds within the joint. It dramatically reduces weed growth, resists wash-out from rain, handles freeze-thaw movement better, and requires far less ongoing maintenance. We always use polymeric sand for resanding jobs because the long-term performance difference is significant.

Patio cleaning & resanding cost in NH
Paver cleaning alone typically runs $150–$350 depending on square footage. Adding polymeric sand resanding increases the cost depending on the patio size and the number of joints that need filling — most standard patios run $300–$600 for the combined cleaning and resanding service. We provide free estimates before any work begins.
