Interlocking pavers rely on joint sand to stay locked together, and rain and traffic wash it out over time. Sealing over worn joint sand just traps the problem, so we clean the pavers, sweep in new polymeric sand where needed, then seal for a consistent, locked-in finish.
Rain and traffic erode polymeric sand over time, letting pavers shift and weeds take hold. We top it up before sealing.
Once sand is gone, gaps open for weeds and insects. Fresh sand and a sealer close that door.
Sun and salt fade pavers unevenly. A sealer restores a consistent finish, low-sheen or wet-look.
We check joint condition and re-sand before sealing, not after.
Natural low-sheen or wet-look, applied evenly across the whole surface.
Garden beds and edging next to the interlock are protected during the job.
Square footage and condition are assessed up front, price confirmed in writing.
We check the joint sand, stone size and layout, then confirm a written price.
We clean the full surface and top up polymeric sand in any joints that need it.
We apply a sealer that locks the sand in place, in a low-sheen or wet-look finish.
We check the finished patio or driveway with you before we leave.
Capital Wash & Seal provides professional interlocking stone and paver sealing throughout Ottawa and the surrounding area. Homeowners call us when joint sand has washed out, pavers have started to shift or sink slightly, or the surface has lost its original colour and sheen after a few Ottawa winters. De-icing salt used on driveways and walkways is one of the main causes of that fading and joint erosion, since an unsealed surface absorbs it directly instead of shedding it. We work on interlocking concrete pavers, natural stone and clay pavers used in driveways, walkways and patios throughout the Ottawa area, replacing polymeric sand in the joints before applying a sealer suited to the stone and the look you want. A typical interlock or paver sealing job in the Ottawa area runs about $0.40 to $0.65 per square foot, confirmed for your specific project in a written quote.
A sealer typically deepens the existing colour somewhat and can add sheen depending on the product chosen, and we can talk through finish options as part of your quote so there are no surprises.
Replacing worn joint sand and sealing over it significantly reduces the gaps that weeds and insects use to get through, though an older installation may still have a few spots that need occasional spot treatment.
Most interlock surfaces in the Ottawa area are resealed every two to three years, depending on sun exposure, traffic and how much winter salt reaches the surface.
Yes, sealer options range from a natural low-sheen finish to a glossier wet-look finish, and we can discuss which suits your property when we quote the job.
Joint sand assessment and replacement where needed is part of a proper interlock sealing job, and the full scope is laid out in your written quote.
Interlock needs to dry out fully before sealer goes down, which typically means a short waiting window after cleaning depending on weather. We schedule the sealing visit accordingly.
