Do Driveways Need Regular Inspections? A Spokane Valley Homeowner's Guide

Why a Crack-Free Driveway Can Still Be Failing Underneath

A driveway can look perfect on top while the ground under it washes out or shifts. Voids, settling, and drainage problems often build for years before the first crack shows up. A driveway inspection catches these hidden problems while they're still small and simple to fix.

No cracks doesn't mean no problems. We tell homeowners that every single week.

Concrete is only as strong as what's under it. Your slab sits on a packed layer of gravel and soil called the subbase. If that layer shifts or washes away, the concrete loses its support. But the top can stay smooth for years while it happens.

A lot of homes in Spokane Valley sit on sandy, gravelly ground. It drains fast. That's good for most things. It also moves easily when water runs through it. Point a downspout right at the slab edge and you've got a slow washout nobody can see.

Then winter shows up. Water slips into small gaps under the slab and freezes. Ice expands, the slab lifts a little. It thaws and drops back down, just not to the same spot. Spokane runs through a lot of freeze-thaw cycles every year. Each one nudges your driveway a bit further out of place.

So what does a failing driveway look like before it cracks? These are the quiet signs we check on every driveway inspection. You can spot most of them yourself with a walk around the slab.

• A hollow, drum-like sound when you tap the slab with a hammer handle
• Water that pools in the same low spot after every rain
• A gap opening up between the slab edge and the dirt beside it
• One panel sitting higher or lower than the one next to it
• A slab that's slowly tilting toward your garage or house

None of these look scary. That's the trouble. Most homeowners walk right past them for years.

We got a call last spring from a homeowner near the Sullivan Road corridor. She wanted a quote on sealing. Her driveway looked great. Not a single crack. But when we tapped near the garage apron, it sounded hollow. A gutter had been draining under that corner for years. There was a void about the size of a laundry basket under the concrete.

That driveway was maybe one hard winter from snapping. Caught early, it was a simple concrete driveway repair. Caught late, it would've been a full tear-out.

Cracks are the last symptom, not the first.

Think of it like a tooth. By the time it hurts, the damage has been building for a while. Same story with a slab that sinks a hair every spring.

And here's the part people miss. Once a slab does crack, water gets a fast lane straight to the subbase. Damage speeds up from there. Each winter pushes it further. A driveway inspection lets you fix the cause before that first crack ever forms.

We've been a local concrete contractor around Spokane for 11 years. We've seen this pattern a hundred times. The cracks always come after the ground gives up. So the smart move is checking what's underneath while the top still looks good.

How Often You Should Check Your Driveway

Twice a year. That's the short answer for most driveways in Spokane Valley.

Spring and fall are the two checks that matter most. Our winters hit concrete hard. Water gets into tiny cracks, freezes overnight, and expands. Then it thaws the next afternoon. Do that dozens of times between November and March, small cracks don't stay small.

So timing your checks around winter makes sense. You catch damage right after it happens. And you seal up weak spots before the next round of freezing starts.

Here's the schedule we tell our own customers to follow:

• Early spring, once the snow is gone. This is your damage report from winter. Look for new cracks, flaking, and spots that sank.
• Late fall, before the first hard freeze. Any open crack now is a doorway for water. Get it filled or sealed before temperatures drop.
• After a heavy snow season or rough plowing. Shovels and blades chip edges. De-icers can eat at the surface over time.
• After a big load sits on it. Moving trucks, dumpsters, and RVs put serious weight on slabs that weren't built for it.
• Every few years, a walk-through with a professional concrete contractor. We spot base and drainage problems most homeowners miss.

None of these checks take long. Ten minutes with a cup of coffee usually does it.

What should you look for? Keep it simple. Walk the whole slab slowly, edge to edge. Check these spots:

• New cracks or old ones that got wider since last time
• Surface flaking or pitting, especially near the garage where snow melts off your car
• Low spots where water puddles after rain
• Edges that are crumbling or pulling away from the lawn
• Any slab that's lifted or dropped compared to the one next to it

Snap a few photos each time. It sounds like overkill, but it's the easiest way to tell if a crack is growing. Your memory won't catch a quarter inch of change. A photo will.

Field tip from our crew: Do your spring check after a rain, not on a dry day. Puddles show you exactly where the slab has settled and where water is sitting against the concrete.

We had a homeowner near the Sullivan Road corridor call us a couple springs back. Hairline crack near the garage. He'd seen it the fall before and figured it could wait. By April, that crack had split the slab and one side had dropped. One cheap fix turned into a much bigger concrete driveway repair.

We see that story every single year.

Age matters too. A newer driveway in good shape can stick to the twice-a-year plan. But once your concrete hits 15 or 20 years, bump it up. Check it every season. Older slabs have more wear and less room for error. And if your driveway sits on a slope or near downspouts, water is already working against you.

Not sure what you're looking at? That's normal. Most cracks look the same until you know what to watch for. In our 11 years doing driveway repair in Spokane Valley, we've learned which ones are cosmetic and which ones mean trouble underneath.

What a Real Inspection Checks For

Most folks picture a driveway inspection as somebody glancing at the slab and nodding. That's not it. A real one is a slow walk with a trained eye. We look at the stuff you already know about. Then we look for the stuff you don't.

So what are we really hunting for? After 11 years of fixing concrete around Spokane Valley, we've got a checklist burned into our heads. Here's what we check on every driveway inspection.

• Crack width and pattern. Hairline cracks are normal. Cracks you can slide a coin into aren't. Spiderweb patterns often point to a weak base underneath.
• Settling and heaving. We check if slabs have sunk or lifted at the joints. A half-inch lip at the garage apron trips people and traps water.
• Surface scaling and spalling. Flaky or pitted spots usually come from freeze-thaw damage or de-icing salt. Once that top layer goes, water gets in faster.
• Drainage. We watch where water runs and where it sits. Puddles along the edge or near your foundation are trouble.
• Joints and edges. Control joints should be clean and sealed. Crumbling edges by the lawn tell us soil is washing out below.
• Sealer condition. If water soaks in instead of beading up, your sealer has quit on you.

That list looks simple. But each item tells part of a bigger story.

Spokane winters do most of the damage here. Water slips into tiny cracks. It freezes, expands, and pushes the crack wider. Then it thaws and does it all again. That cycle can repeat over and over in a single winter. So a crack that looked harmless in October can look ugly by March.

We've seen this crack pattern a hundred times, and it almost always starts small.

Here's a real example. A homeowner near the Sullivan Road corridor called us about one crack near the garage. Just one. When we walked the whole slab, we found the real problem. A downspout was dumping water right at the driveway's edge. The soil under that corner had washed out, and the slab was starting to sink. Patching the crack alone wouldn't have lasted a season. Redirecting that water came first. After that, concrete crack repair had a shot at holding.

Why does that matter to you? Because a good inspection finds the cause, not just the symptom. Patch the symptom and you'll be fixing the same spot twice. Most homeowners wait too long and learn that the hard way.

And we'll tell you straight when nothing needs doing. Not a sales pitch. Plenty of driveways just need fresh sealer and a check-in next year. Others need concrete crack repair or driveway resurfacing before the next freeze hits. A few are past saving.

But you won't know which group yours falls in until someone looks.
