Key takeaways
- Most patio problems come from a weak base or poor drainage.
- Restoration (lift, rebuild base, reset, re-sand) can bring a patio back to like-new.
- Replace when the whole patio has settled or pitches toward the house.
- Cleaning and sealing can restore paver color.
A patio that’s sunk, heaved or overgrown with weeds doesn’t always need to be torn out. Many Middletown patios can be restored for far less than replacement.
Common patio problems
- Sunken or uneven pavers
- Loose or rocking bluestone and flagstone
- Crumbling mortar joints
- Weeds and ants in the joints
- Water pooling against the house
- Faded, stained pavers
How restoration works
- Lift pavers or stones in affected areas
- Rebuild and compact the base, correcting pitch
- Reset the original materials, replacing broken pieces
- Re-sand joints with polymeric sand, or repoint mortar joints
- Clean and optionally seal to restore color
When to replace
If the entire patio has settled, was built on bare soil, or slopes toward your foundation, a new patio with a proper base is the better investment.

Troubleshooting: common problems and fixes
Here’s how we diagnose and fix the issues we see most often on projects like this.
Bayshore homes with salt exposure
What you see: Faster wear on masonry and paving in Belford, Port Monmouth and Leonardo.
Why it happens: Salt air and coastal storms.
How we fix it: Salt-tolerant materials, compatible mortars and drainage that sheds storm water quickly.
How to prevent it: Spring rinsing and sealing.
Long drives in Lincroft and Navesink
What you see: Worn estate-style driveways and broken Belgian block.
Why it happens: Age and heavy use.
How we fix it: Rebuilds, overlays and Belgian block resetting.
How to prevent it: Regular sealcoating.
Hot surfaces and slippery spots
What you see: The patio is too hot to walk on barefoot, or slick when wet.
Why it happens: Dark materials absorb heat, and smooth finishes lose grip, especially around pools.
How we fix it: We recommend lighter, textured pavers or thermal-finished bluestone around pools and high-sun areas.
How to prevent it: Choose finish and color for the location, not just the look in a catalog.
Heaving after winter
What you see: Sections of pavers have lifted, often near the house or where water collects.
Why it happens: Water in a poorly draining base freezing and expanding. Frost-susceptible soils make it worse.
How we fix it: We rebuild the base with free-draining stone, correct the pitch and address the water source (downspouts, grading).
How to prevent it: Proper base material and drainage prevent heaving. This is the most important detail on any paver job.
The patio slopes toward the house
What you see: Rainwater runs back to the foundation, the door threshold or the basement window wells.
Why it happens: The patio was built flat or settled near the house, where backfill soil is often loose.
How we fix it: We rebuild with a compacted base and a consistent pitch of about 1/8–1/4″ per foot away from the house, and add a channel drain where needed.
How to prevent it: Make pitch and drainage part of the design conversation before anything is built.
What affects the cost
- Size and shape
- Material: pavers, bluestone, flagstone, concrete
- Removal of an old patio or slab
- Steps, seat walls, fire pits and planters
- Drainage needs near the house
- Access to the back yard for machines
- Lighting and electrical for low-voltage path or wall lights
Mistakes to avoid
- Building the patio too small
- Ignoring the path from the kitchen door
- Forgetting pitch and drainage
- Mortar-setting stone over a weak slab
- Picking dark, smooth materials for a sunny pool deck
- Using a patio-depth base for a driveway
Seasonal care checklist
- Spring: Sweep, refill joints, and check for loose stones or settling.
- Summer: Enjoy it. Clean grill grease promptly.
- Fall: Remove leaves and protect furniture.
- Winter: Avoid metal shovels on stone, and use gentle ice melt.
Frequently asked questions
Can sunken pavers be fixed without replacing them?
Yes. We lift them, rebuild the base and reset the same pavers.
Should I seal my pavers?
Sealing is optional. It enhances color and makes cleaning easier, and is typically renewed every few years.
Why is water running toward my house from the patio?
The patio was built flat or has settled near the foundation. Rebuilding with a pitch of about 1/8–1/4 inch per foot away from the house fixes it.
Can you make my patio bigger?
Yes. We extend patios in matching or complementary materials, or add a second level with steps or a seat wall.
Why are my pavers sinking?
Usually a thin or poorly compacted base, or water undermining it. The fix is to lift the pavers, rebuild the base in compacted lifts and reset them.
