Winter in the Bay Area brings much-needed rain, but it also poses challenges for outdoor surfaces like paver patios, walkways, and driveways. If your paver project isn’t
properly maintained before the wet season, water can seep into the joints, causing damage, shifting, and erosion. Taking the time to clean, seal, and re-sand the joints of your pavers now can protect your investment and keep your outdoor space looking great for years to come.
As a new company eager to serve Bay Area homeowners in the new year, we want to share practical advice on how to prepare your paver project for the rainy season. These steps will help you avoid costly repairs and maintain the beauty and durability of your hardscape.
Why Powerwashing and Sealing Your Paver Joints Matters
Over time, dirt, debris, and organic matter accumulate in the joints between pavers. This buildup can trap moisture and promote weed growth, which weakens the joint material and destabilizes the pavers. Before the rainy season arrives, cleaning out these joints removes harmful debris and prepares the surface for sealing and sanding. Powerwash and seal of pavers is the solution.
How to clean your paver joints:
Use a stiff broom or a specialized joint cleaning brush to sweep out loose dirt.
For stubborn debris, a pressure washer on a low setting can help, but avoid high pressure that might dislodge sand.
Remove any weeds or moss growing between the pavers by hand or with a weed killer safe for hardscapes.
Cleaning ensures that the joints are free of materials that can trap water or cause erosion during heavy rains.
The Importance of Pressure washing and Sealing Your Pavers
Sealing your paver surface creates a protective barrier that repels water and prevents stains. A good sealant also strengthens the bond between pavers and joint sand, reducing the risk of sand washout during rainstorms.
Benefits of sealing:
Prevents water infiltration that can cause shifting or sinking.
Protects against mold, mildew, and algae growth.
Enhances the color and appearance of your pavers.
Makes cleaning easier throughout the year.
Choose a sealant designed for your specific paver material, whether concrete, brick, or natural stone. Apply the sealant evenly with a sprayer or roller on a dry day, ideally before the first heavy rain.
Why Re-Sanding the Joints Is Essential
Joint sand stabilizes your pavers by locking them in place and preventing movement. Over time, rain and foot traffic can wash away this sand, leaving gaps that allow water to penetrate and damage the base layer.
Re-sanding fills these gaps and restores the strength of your paver surface. Use polymeric sand, which hardens when moistened, providing superior resistance to erosion and weed growth.
Steps for re-sanding:
After cleaning and sealing, spread polymeric sand evenly over the pavers.
Sweep the sand into the joints using a broom.
Remove excess sand from the surface.
Lightly mist the joints with water to activate the polymeric sand.
This process creates a durable joint that withstands winter rains and keeps your pavers stable.
Timing Is Key for Winter Preparation
The Bay Area’s rainy season typically starts in late fall and continues through winter. It’s best to complete cleaning, sealing, and re-sanding before the first significant rains arrive. This timing ensures your paver project is fully protected when moisture levels rise.
Waiting until after the rain begins can cause problems:
Wet joints won’t hold new sand properly.
Sealants won’t adhere well to damp surfaces.
Water damage may already start affecting your pavers.
Plan to perform these maintenance steps in early to mid-fall to avoid these issues.
Why Choose a Professional Service
While some homeowners may attempt these tasks themselves, professional paver maintenance offers several advantages:
Expertise in selecting the right sealants and sand for your specific paver type.
Proper equipment to clean joints thoroughly without damaging pavers.
Efficient application of sealants and sand for long-lasting results.
Inspection for underlying issues like base erosion or settling that may need repair.
