It is practical and aesthetically rewarding to use interlocking stones to construct driveways, not only because they look better, but because of their durability that spans up to four decades, which is a total win if we take into account Ontario’s wide temperature swings. The stone pavers are easy to lay and are available in different sizes, patterns and designs so that you can easily create your own practical and personalized driveway – and don’t have any trouble in maintaining it. It is nevertheless essential to observe several simple rules to prolong the longevity of your interlocking driveway – today, our experts in tiling work dish their secrets on how to use your sophisticated stone paver driveway in a way that will spare you the trouble of renovating it in years to come!
Why Regular Interlock Maintenance Matters
A professionally constructed interlocking driveway is an area that you can enjoy for many years. The surface is low-maintenance, but like all outdoor surfaces, there is a gradual soiling through pollution caused by air and traffic. Neglecting routine care can lead to weed infiltration, joint erosion, and surface staining that becomes increasingly difficult and expensive to reverse. Regular maintenance preserves not only the visual appeal of your investment but also its structural integrity, preventing pavers from shifting or settling unevenly. Proactive cleaning and joint care extend the lifespan of your interlock by decades, protecting against premature wear from Ontario’s freeze-thaw cycles. Most importantly, a well-maintained driveway, walkway, or patio enhances your property’s curb appeal and overall value, making it a smart financial decision as well as an aesthetic one.
Step-by-Step Interlock Maintenance and Cleaning Tips
Basic Paver Cleaning Steps
The most effective way to clean interlock pavers is by using a high-pressure washer. This method easily removes dirt caused by air and traffic pollution, along with algae, oil stains, and grime that settle deep in the joints. A pressure washer restores the original color and texture of the pavers without the need for harsh chemicals or excessive scrubbing. For best results, use clean water or add a small amount of mild detergent for stubborn areas. Regular high-pressure cleaning not only keeps your paving stones looking fresh but also helps maintain their longevity by preventing buildup that can damage the surface over time.
For those searching for interlocking paver cleaning methods that really work, consistency is key. Don’t wait until your driveway or patio looks neglected. Regular maintenance not only keeps the surface looking fresh but also helps you spot potential issues before they become expensive problems.
Removing Moss, Algae, and Efflorescence
On terraces, interlocking walkways, and driveways, the stone may, in some cases, get a coating of algae, fungi, or moss. If you need to remove moss from pavers, start with brushing and a paver-safe outdoor cleaner; use targeted, manufacturer-approved biocides only as directed and rinse thoroughly. Many homeowners also find that specialized brick paver patio maintenance products work brilliantly for stubborn growth.
To remove algae from pavers, act quickly before it spreads and becomes slippery. Algae thrives in shaded, damp areas, so improving drainage and sunlight exposure can prevent future problems with your interlock walkway installation. For brick patio maintenance, keeping the surface dry and well-ventilated is half the battle.
You might also notice efflorescence on concrete pavers – that white, powdery residue that appears on the surface. This lime precipitation is completely normal and doesn’t damage your pavers; it’s simply part of the concrete’s natural curing process. Efflorescence often fades naturally over time with weathering and periodic rinsing. For persistent efflorescence, use a dedicated efflorescence remover approved for concrete pavers, following a small-area test and label directions.
Handling Oil, Rust, and Paint Stains
Use a paver-safe degreaser and gentle brushing; avoid abrasive powders that can scratch the surface. Different types of degreasing products also work well. Fresh oil stains should be soaked up immediately with paper, cloth, or sawdust to prevent them from setting in. The good news? Oil may not structurally damage the paver, but it can stain and be difficult to remove if not treated quickly.
For solvent-based paint, use a paver-approved remover and follow label instructions after a small test area. Water-based paint can be lifted with a damp cloth, followed by washing the surface clean with water.
Rust stains can be removed with gentle brushing and a paver-safe rust remover.
Joint Sand and Surface Protection
Refilling and Compacting Paver Joints
The joints between your interlock pavers are far more important than most people realize. These spaces aren’t just gaps – they’re structural elements that keep your entire driveway or patio stable and functional. A properly filled joint prevents the pavers from shifting, helps with water drainage, and makes it much harder for weeds to take root.
Weather and wind naturally remove some joint material over time, which is why you’ll need to refill them periodically. For enhanced protection and durability, we recommend using polymeric sand. This specialized material hardens when activated with water, creating a more stable joint that resists erosion and helps prevent weed growth more effectively than regular sand.
When refilling joints, sweep the sand across the surface in multiple directions to ensure complete coverage, then compact with a plate compactor (with a pad); lightly mist only to activate polymeric sand. Proper aftercare of your joints is essential for long-term stability.
Sealing Driveways, Patios & Walkways
Sealing isn’t mandatory, but it’s an excellent protective aftercare step—especially for driveways. A breathable, high-quality sealer:
✔ Enhances colour and makes routine cleaning easier.
✔ Minimizes UV fading, road film, and stain penetration.
✔ Helps stabilize polymeric sand and limit weeds.
Seal once the surface is clean and dry and initial efflorescence has subsided; follow the sealer manufacturer’s timing guidance. Clean thoroughly, let the surface dry, apply in ideal weather, and respect cure times. Not sure where to start with how to clean interlock pavers before sealing?

Seasonal Care for Interlocking Pavers
Spring & Summer Tips
Spring is the perfect time to give your interlock a complete refresh. Start by pressure washing the paving stones to remove dirt, salt, and grime left behind by winter. This deep cleaning not only restores their natural color but also prepares the surface for maintenance. Once the area is clean and dry, inspect the joints and refill them with sand where needed to keep the pavers stable and prevent shifting or weed growth. This is also the ideal season for regular maintenance tasks like sealing.
Summer brings its own challenges. Keep an eye out for weed growth between pavers and address it promptly. Knowing how to keep patio pavers clean during barbecue season means dealing with spills quickly and hosing down the area after gatherings to prevent staining.
Fall & Winter Protection
Winter and snow aren’t only about sparkling landscapes plus hot chocolate. It also brings visible and hidden ice on walkways and driveways, which is a hassle. While salting is a popular method with often good results, it’s not particularly gentle on the surface or the surrounding environment.
De-icing salt can be harmful to interlock surfaces, as it may cause surface flaking and discoloration. However, modern ice melters designed specifically for concrete and pavers offer a safe alternative. These products effectively melt ice and snow without damaging the surface, making them an excellent choice for winter care and protection of your paving stones.
Thus, winter maintenance of paving stones consists of quickly clearing snow with a shovel and applying an ice melter. This approach helps maintain the integrity of your investment without causing chemical deterioration. For snow, use a plastic shovel rather than a metal one to avoid scratching the surface.
After winter storms, rinse surfaces where cars are regularly parked. The slush in wheel arches often contains concentrated amounts of salt that gradually wear away at the concrete surface over time.

Frequently Asked Questions
How often should interlock driveways be re-sanded or sealed?
Re-sand joints whenever you notice depletion—often after heavy weathering or washing rather than on a fixed schedule. Sealing intervals vary by exposure, traffic, and product; many driveways need re-sealing roughly every 2–5 years. Regular inspection helps you catch issues early.
Can pressure washing damage interlocking pavers?
Use a wide fan tip at low pressure, 12–16 inches from the surface, to avoid dislodging joints or etching. However, using too much pressure or holding the nozzle too close can erode joint sand and even damage the paver surface. It’s best to use a wide-angle nozzle and moderate pressure, or hire professionals who know the right technique.
What’s the best season for interlock maintenance in Ontario?
Late spring through early fall provides the dry, mild conditions needed for joint work and sealing. Book ahead because prime weeks fill quickly.
How long does professional interlock maintenance take?
Most single-day projects (clean + re-sand + compact) wrap up in a few hours, depending on size and condition. If sealing is included, add cure time—often pedestrian-ready the next day and driveway-ready after the product’s stated window.
