Your patio, walkways, and retaining walls represent a significant investment, and Northern Nevada winters test them hard. Freeze-thaw cycles exploit any weakness — an open joint, a worn sealer, a clogged drain — and turn small issues into expensive repairs by spring. A short pre-winter inspection catches those weaknesses while it's still easy to fix them. Here's what to look at.
Inspect and refresh paver joints
Walk your paver surfaces and check the joints. Polymeric joint sand can wash out or wear down over time, and open joints let water penetrate the base — where it freezes, expands, and heaves pavers unevenly. Refilling and, where needed, re-locking the joints before winter keeps water out of the base.
Look also for any pavers that already rock or sit low; addressing them now prevents the freeze-thaw from making them worse.
Consider sealing
A quality sealer helps protect pavers from moisture intrusion, staining, and surface wear, and can reinforce the joints. Fall, when surfaces are dry and before the freezes set in, is a good window to seal. Sealing isn't mandatory for every project, but on premium or high-traffic surfaces it extends the life and keeps the look sharp.
Check retaining wall drainage
Retaining walls live or die by drainage, and winter is when poor drainage does its damage. Check that any weep holes or drain outlets are clear and flowing, that surface water sheds away from the top of the wall rather than pooling behind it, and that there's no new bulging, leaning, or cracking that signals building pressure.
Clearing a blocked drain or correcting grade before winter can prevent the hydrostatic pressure that pushes walls out of plumb during freeze-thaw.
Catch small problems early
The theme of a pre-winter inspection is simple: small, cheap fixes now prevent large, expensive ones later. A washed-out joint or a clogged drain is minor in October and a heaved patio or leaning wall by April.

Pro insight: joints and drains, not just the surface
A five-minute pre-winter walk saves the most expensive spring repairs on hardscape. The two things we check first are paver joints and wall drainage, because both let water into places freeze-thaw can wreck. Open joints let water into the base where it heaves pavers unevenly; a blocked wall drain lets pressure build behind the wall.
Neither fix is glamorous — refill and re-lock the joints, clear the weep holes and drain outlets, correct any grade that sends water the wrong way. But doing it in October is a minor task; discovering it in April is a heaved patio or a leaning wall.
- Refill and re-lock paver joints so water can't reach the base
- Seal premium or high-traffic surfaces while they're dry
- Clear weep holes and drain outlets on retaining walls
- Correct grade so surface water sheds away, not behind walls
The bottom line
A short pre-winter check — joints, sealing, and wall drainage — turns expensive spring repairs into minor fall tasks. Freeze-thaw exploits every open joint and blocked drain, so close them before the cold arrives.

Frequently Asked Questions
Not every year. Sealing every few years protects premium or high-traffic pavers from moisture and staining and reinforces the joints. Fall, while surfaces are dry, is a good window.
Open joints let water into the base, where it freezes and heaves the pavers unevenly. Refilling and re-locking the joints before winter keeps water out and the surface flat.
Watch for bulging, leaning, or new cracks, and check that weep holes and drain outlets are clear and flowing. Blocked drainage is what builds the pressure that pushes walls out of plumb during freeze-thaw.
Fall, once the surface is clean and dry and before the hard freezes set in. Sealing then protects against moisture intrusion and staining through winter and reinforces the joints. It's not needed every year — every few years is typical for premium or high-traffic surfaces.
