Driveway sealcoating in Victoria BC
Asphalt on the South Island does not usually fail because of frost. It fails because rain and ultraviolet light strip the binder out of the top few millimetres until the stones let go. Sealing puts that protective layer back.
What sealcoating does, and what it does not
Asphalt is stone held together by bitumen. Ultraviolet light oxidises that binder and rain washes the oxidised layer away, which is why an old driveway turns from black to grey and then starts shedding loose aggregate. Once enough binder has gone, water gets between the stones, and from there you are on a fast path to potholes.
A sealcoat is a thin protective film over the top. It replaces the surface layer the weather has taken, blocks water and oil from getting into the mat, and restores the colour. Applied on a reasonable cycle it meaningfully extends how long a driveway lasts before it needs resurfacing.
It is not a structural product. It will not lift a sunken section, will not bridge a crack on its own, and will not rescue a driveway whose base has failed. Anyone selling sealcoating as a repair is selling you paint. Cracks get filled as a separate step first, and a pothole needs a patch before anything goes over it.
Driveway sealcoating frequency British Columbia
Every two to four years is the working range for a residential driveway in this part of British Columbia, and where you sit in that range depends on exposure more than on age.
Full sun shortens the interval because ultraviolet light is what breaks the binder down. Heavy tree cover shortens it a different way: shade keeps a surface damp for months, moss establishes in the texture, and organic acids and root lift do the rest. Sooke and the wetter western end of the region see more annual rainfall than Sidney does, and that shows up in how fast a surface ravels. A driveway that gets a car turning on it several times a day wears faster than one used twice.
The practical test is not the calendar. Look at the surface: if the black has gone grey and you can see individual stones standing proud, or you can brush loose aggregate off with your foot, the binder is gone from the top layer and it is time. Sealing far more often than that is money spent on film thickness you do not need, and thick over-applied sealer can crack on its own.
How often to sealcoat asphalt driveway
Three cases worth separating, because the general answer misleads in each of them.
- A brand new driveway. Do not seal it yet. Fresh asphalt needs months to release its lighter oils, and sealing early traps them and leaves a soft surface that scuffs and tracks. Wait until the mat has weathered from black to a duller grey, generally six months to a year here.
- A driveway sealed on schedule for years. Stretch to the longer end of the range. Each coat adds film thickness, and a heavy stack of old sealer is more prone to cracking than the asphalt under it.
- A driveway that has never been sealed. Do not start with sealer. Start with an assessment. If the surface has already ravelled badly, sealing over loose aggregate glues down something that is already coming apart. Sometimes the right answer is a resurfacing job or nothing at all until the driveway is replaced, and we would rather tell you that than take the work.

How the job runs on your driveway
Cleaning first, and thoroughly. Loose material is blown and swept off, oil spots get a primer because sealer does not bond to oil, and moss and organic growth are removed rather than sealed under. On a shaded Oak Bay or Sooke driveway this is often the longest part of the day.
Cracks get filled next. Anything wide enough to take material is cleaned out and filled so water stops getting into the base. Edges where the mat has ravelled away get attention here too, because that is where failure usually starts.
Then the sealer goes down, cut in by hand at the edges and applied across the body of the driveway. Cure needs dry weather on both sides of the application, so we watch the forecast and will move your date rather than lay product into a wet week. You stay off it for the cure period, which we give you in writing, and the driveway comes back into service after that.
Concrete rather than asphalt? That is a resurfacing or sealing job instead, and a completely different product.

- Garage floor epoxyWe grind the slab back to clean concrete, test it for moisture, then build a flake or solid-colour coating that stops the dusting and shrugs off road salt.
- Concrete resurfacingA cementitious overlay bonded over your existing driveway, patio or walkway. Cracks get cut and filled first, so the new surface is not just paint over a problem.
