Hardscaping adds structure, value, and beauty to outdoor spaces. Whether it’s a driveway made of pavers, a concrete patio, or a stone walkway, regular cleaning is essential to maintain the appearance and integrity of these surfaces. Knowing how the process works can help you protect your investment and keep your outdoor areas looking their best.
1. Inspection and Preparation
Before any cleaning begins, professionals assess the condition of the surface. Reputable hardscape companies will check for loose pavers, cracks, weeds, and any areas needing repair. They’ll also look at the type of stains present—whether from mold, algae, oil, or dirt—and plan the cleaning method accordingly.
Once inspected, the area is cleared of furniture, debris, and plant overgrowth. This prep work ensures a more thorough and efficient clean.
2. Surface Sweeping and Weed Removal
Next, the cleaning team sweeps the area to remove loose debris like leaves, dirt, and pebbles. Weeds growing between hardscape pavers are pulled out by hand or with specialized tools. In some cases, a weed killer is applied to prevent regrowth.
3. Pressure Washing
The main cleaning method used on concrete hardscape and paver surfaces is pressure washing. This technique uses high-pressure water to blast away grime, mold, and stains without damaging the material. Depending on the surface, the technician adjusts the water pressure to avoid loosening or chipping the pavers.
For more delicate or decorative stone, a soft wash method with special cleaning solutions may be used to prevent damage while effectively cleaning the surface.
4. Stain Treatment
If there are deep or stubborn stains—such as oil spots or rust—spot treatments are applied. These targeted cleaners break down the stain without harming the pavers or surrounding landscaping. Professionals use eco-friendly products that are safe for the environment and nearby plants.
5. Joint Sand Replacement (for Paver Surfaces)
After pressure washing hardscape pavers, the sand between the joints may be washed away. Replacing this sand is crucial to keep the pavers in place and prevent weed growth. Technicians sweep in new polymeric sand and compact it to secure the surface.
6. Sealing the Surface
The final step in the process is sealing the cleaned surface. Sealants protect against stains, water damage, and color fading. For concrete hardscape, sealing also adds a subtle sheen that enhances its appearance. Homeowners can choose between natural matte or gloss finishes based on their preferences.
Sealing is not always necessary but is highly recommended for high-traffic areas or surfaces exposed to the elements year-round.
Why Hire Professionals?
While DIY cleaning is possible, working with experienced hardscape companies ensures proper techniques, long-term protection, and time savings. Professionals have access to commercial-grade equipment and the expertise to treat different surface types safely and effectively.
If your outdoor space is looking weathered or stained, scheduling a professional hardscape cleaning can make a dramatic difference. Not only will it restore beauty, but it can also extend the life of your surfaces.
