Paver & Interlock Cleaning & Sealing in Halifax

Cleaning makes them look good again, but sealing is what makes it last. A clean on its own clears the moss, weeds and stains, and if that’s all you want, that’s a fair option. The catch is that without sealing, the joints stay open, so the weeds and growth come back, and the sand keeps washing out. Sealing locks it all in, protects the colour and makes the surface much easier to keep clean. If you’re cleaning them anyway, sealing at the same time is what gets you years out of the work instead of a season.

Most paver surfaces here do well with a clean once a year and a reseal every two to three years. Our damp weather and freeze and thaw winters are harder on pavers than a dry climate, so shaded patios and high-traffic driveways can be on the shorter end of that.

Sealing is typically done every 3–5 years, depending on traffic, sun exposure, and the type of sealer used.

It won’t make them disappear forever, but it makes a big difference. The weeds and moss take hold in open, sand-starved joints, so once we re-sand the joints and seal the surface, there’s far less room for them to root and far less moisture sitting on top. You’ll see a lot less of it, and what does appear wipes or rinses off easily instead of digging in. Sealed pavers are much less work to keep clean than bare ones.

That white, chalky haze is efflorescence, and it’s salt and minerals working their way out of the concrete as moisture evaporates from the pavers. It’s natural and it doesn’t mean the pavers are failing, but it does dull the look. We can treat and remove it as part of the cleaning, and sealing afterward helps slow how much of it comes back to the surface.

A natural finish keeps the pavers looking the way they do now, just clean, with no added sheen. A wet look, or enhanced finish, deepens the color and adds a slight sheen, like the pavers look right after rain. It comes down to taste. Some people love the richer wet look, others want their patio to look untouched. Both protect the same way. We’ll show you the difference before you decide.

Yes, we can. But this is a re-levelling job, not part of a standard clean and seal. When pavers heave or dip, it’s usually the base underneath that’s moved, so they have to be lifted, the base re-levelled, and the pavers reset before any sealing makes sense. We’ll assess it during the estimate and tell you honestly whether you’re looking at a clean and seal or whether some areas need re-leveling first.

Plan to keep foot traffic off for about 24 hours and vehicles off for 48 to 72 hours, though it depends on the sealer and the weather on the day. Damp or cool conditions slow the cure, which is one more reason we don’t rush it. We’ll give you exact timing when we finish so you know when it’s safe to walk and park on again.

It depends on the size of the area, the condition of the pavers, and whether you want a clean only or a full re-sand and seal.
