Concrete guides you can watch.
Short walkthroughs of the concrete jobs every San Diego homeowner can do safely, sealing, crack fills, patio cleaning, prep work. Each guide comes with step-by-step instructions and a clear line on when to call a pro.
What concrete maintenance can you do yourself?
How to seal a concrete driveway
Sealing is the highest-leverage maintenance you can do on a concrete driveway. The product, the temperature window, and the surface prep matter more than the application itself.
How to fill small concrete cracks
Hairline and quarter-inch cracks are the most common concrete repair homeowners can do safely. Anything wider, stepped, or growing should be diagnosed by a contractor first.
How to clean a stained concrete patio
Oil, rust, leaf tannins, and BBQ grease are the four most common patio stains. The right cleaner matched to the stain saves the surface; the wrong one bleaches concrete or strips sealer.
How to prep a site for a concrete pour
Most concrete failures trace back to bad base prep. Even the best concrete fails when the base is wrong. Here is what proper prep actually looks like before the truck arrives.
When should you stop and call a professional?
Six signs that the problem is past DIY. Turn the system off and pick up the phone, running a system with these issues turns cheap repairs into expensive replacements.
- Cracks wider than half an inch or growing
Indicates structural movement or base failure. Patching without diagnosing the cause makes the problem worse.
- One side of a crack visibly stepped
Settlement crack. Needs polyurethane lift or replacement, not surface filler.
- Slab rocking or pumping water
Void under the slab. Continuing to use the slab will crack it further. Needs lift or replacement.
- Rust stains pushing through the surface
Rebar corrosion from below. Needs cut-out and partial pour with epoxy-coated bar, not just a topical patch.
- Wet basement or crawl space below the slab
Water is finding a path through cracks. Structural issue that requires drainage diagnosis before any patch holds.
- Foundation cracks over 1/8 inch
Foundations carry the structural load. Even small cracks should be evaluated by an engineer or experienced contractor before injection or patch.
