Mighty Buildings Driveway & Pavers: The San Francisco Owner’s Guide
We stock and install Mighty Buildings-compatible driveway and paver systems throughout San Francisco. A full paver driveway installation in this market runs $8,260 – $21,240, and a partial repair or section replacement typically lands between $1,500 and $4,000 depending on the failed area and base condition. Most owners don’t discover the failure until they see standing water pooling where it used to drain, or a paver has sunk a half-inch below its neighbors after a wet winter.
Here’s what we know from working driveways and hardscapes across the city: the Mighty Buildings product line uses modular paving systems sized differently than the big-box paver brands, and that sizing matters when you’re replacing a section. San Francisco has its own set of problems too. Fog-driven moisture, clay soils in the Sunset and Richmond districts, and the constant freeze-thaw cycles that hit the hillier neighborhoods near Twin Peaks all work against a driveway’s base layer. This page covers what fails first, what a fix costs, and what we’d do if it were our driveway.
Key Takeaways:
- Mighty Buildings pavers are modular and spec’d differently from standard Belgard or Unilock units. You can’t always drop in a big-box paver as a field replacement.
- Installed paver driveway cost in San Francisco: $8,260 – $21,240. Sectional repair work usually falls between $1,500 and $4,000.
- We carry Mighty Buildings-compatible pavers plus documented equivalents from Belgard and Unilock, so you aren’t stuck waiting on a single supplier.
- Written price before any work starts, and a 365-Day Done Right Promise on every paver and driveway job we complete.
Which Mighty Buildings Models This Applies To
Mighty Buildings manufactures modular paving and driveway components rather than a single monolithic product line. In practice, that means the pavers we see on San Francisco driveways come from their standard series, typically 24″ × 24″ and 24″ × 36″ modular concrete units with a tongue-and-groove edge profile. The gotcha: those dimensions don’t match the 4″ × 8″ or 6″ × 9″ units you’ll find at a home center. If you mix a standard retail paver into a Mighty Buildings field, the joint lines will never line up and the elevation across the surface will be visibly off.
Identifying your exact Mighty Buildings paver comes down to two things. First, check the underside: Mighty Buildings units carry a molded stamp with the series code and a date of manufacture, usually in a recessed oval near one corner. Second, measure the top face. If the unit is 24″ on one side and has a machined edge profile, that’s the Mighty Buildings modular series. We’ve also encountered their smaller 16″ × 16″ unit used for walkways and patio transitions, and that’s a different SKU entirely.
OEM versus aftermarket: for Mighty Buildings specifically, we lean OEM on matched replacements because the edge profile is not replicated perfectly by most aftermarket units. For broader paver work where the whole surface is coming out and being reset, Belgard and Unilock make excellent documented equivalents that we install with full confidence. The decision comes down to whether we’re patching a section (go OEM) or rebuilding the driveway (your brand choice, priced in writing before we start).

Signs Your Mighty Buildings Driveway & Pavers Is Failing
- Standing water in low spots. A properly graded paver driveway sheds water to the street or a drain. If you’re seeing puddles that linger for more than a couple hours after rain, the base layer has likely settled or washed out under the pavers. In the Outer Sunset and Richmond, this is almost always a base failure, not a paver failure.
- Sunken or raised pavers. One paver sitting a half-inch low while the one next to it is flush means the compacted base beneath that paver has failed. This is the earliest visible symptom of a failing Mighty Buildings driveway, and it’s the one where early repair saves real money.
- Crumbling edges or corner spalling. The Mighty Buildings modular units carry load at their edges. Once a corner chips or crumbles, moisture gets into the joint and starts eroding the base layer during every freeze-thaw cycle San Francisco sees on the city’s higher slopes.
- Joint sand washing out repeatedly. If you sweep polymeric sand into the joints and it’s gone in a month, the base is moving. That movement grinds the paver edges against each other, accelerates wear, and shortens the life of the whole installation.
- Cracks running through multiple pavers in a line. A single cracked paver is a replace-it job. A crack line that runs through several pavers in a row tells us the subgrade has moved, usually from water intrusion or an adjacent tree root. That’s a base repair, not a paver swap.
If you’re seeing two or more of these at once, the driveway is telling you the base has reached the end of its service life. Paver units themselves can last decades; the most common San Francisco failure we repair is a base layer that was never compacted for our soil and moisture conditions.
Replacement Cost & What’s Included
For a full Mighty Buildings-compatible paver driveway in San Francisco, installed, the range is $8,260 – $21,240. The spread comes from square footage, the condition of the existing base, access for equipment, and whether we’re pulling a permit. A partial repair, where we cut out a failed section, recompact the base, and reset or replace pavers, typically runs $1,500 – $4,000 depending on how deep the base repair goes.
Here’s the breakdown in writing, the same way we’d give it to you before the job starts:
| Scope | Installed Price Range (San Francisco) |
|---|---|
| Sectional paver repair (failed base, reset 50 – 200 sq ft) | $1,500 – $4,000 |
| Full Mighty Buildings paver driveway replacement | $8,260 – $21,240 |
| New base install (excavation, compaction, geotextile, gravel, sand) | Included in full replacement; $800 – $2,200 standalone if repair scope expands |
| Concrete driveway (alternative to pavers) | $5,310 – $14,160 |
| Asphalt paving (alternative to pavers) | $4,130 – $10,620 |
| Driveway sealing (paver or concrete) | $295 – $825 |
Every quote includes written line-item pricing before a single tool comes out. That means the price you approve is the price on the invoice, and the 365-Day Done Right Promise covers the work for a full year. If the driveway fails inside that window, we return and correct it at no charge.

What you can safely do yourself: identify the symptoms from the list above, photograph the failure from multiple angles, and measure the affected area. Knowing your square footage and whether the pavers are the 24″ or 16″ modular units helps us price the job over the phone. You can also check whether water is draining away from the house, because that points to a grading issue separate from the paver condition.
What you shouldn’t do is start pulling pavers without knowing what’s underneath. A Mighty Buildings driveway is a load-bearing system, and the base layer under a failed section is often eroded in ways that aren’t visible from the surface. If you pull units and dig, you can undermine the adjacent pavers and turn a $2,000 repair into a $12,000 replacement. The paver units themselves are heavy, the base excavation typically goes 8 – 12 inches deep, and San Francisco’s hillside clay demands proper compaction or the repair fails inside a year.
If the driveway is showing any of the symptoms above, call us at (831) 610-5598. We’ll walk the site, give you a written scope and price, and you’ll know exactly what you’re paying before anything gets dug up.
Frequently Asked Questions
A properly installed Mighty Buildings paver surface should last 30 – 50 years in San Francisco, but the base layer typically fails after 15 – 25 years due to soil movement and moisture. The pavers themselves rarely wear out; what fails is the compacted base underneath. Call (831) 610-5598 if you suspect your base is going, and we’ll give you an honest read before it becomes a full replacement.
Yes, a single cracked or sunken paver can usually be cut out and reset or replaced without touching the rest of the driveway, provided the base under that paver is still solid. If the base has failed, just swapping the paver won’t hold, and the fix becomes a base repair. We’ll tell you which one you’re dealing with after we look under the surface.
A full Mighty Buildings-compatible paver driveway replacement in San Francisco typically takes 5 – 10 working days, including excavation, base compaction, paver installation, and joint sand. A sectional repair can often be done in 1 – 2 days. Your written quote will include a start date, a completion window, and the exact scope so there are no surprises at close-out.
We keep a working inventory of the most common Mighty Buildings modular paver sizes on hand, which means many sectional repairs start the same week we price them. If your job needs a full driveway’s worth of material, we’ll order it with the written quote and tell you the lead time before you commit. Call (831) 610-5598 to find out what’s in stock for your exact unit size.
