Patio Maintenance – 9 Common Patio Problems and How to Fix Them

A well-maintained patio can be a delightful addition to any home, providing a perfect space for outdoor relaxation and entertainment. However, patio maintenance can be a hassle, especially if you let small problems slide as they eventually turn into bigger problems.

That’s why it’s important to know what patio problems to look for when it comes to maintaining your outdoor space. This article will give you some common issues that happen with patios as well as provide a solution to fixing them.

Patio Maintenance

Your garden and backyards are exposed to the elements, making them susceptible to various patio problems. Addressing these issues promptly can extend the life of your patio and keep it looking its best.

How Long Should a Patio Last?

With proper patio maintenance and care, patios made of brick, concrete, or pavers could last 20-25 years. However, this is also dependent on the quality of the work done when the patio was installed.

If the patio isn’t sealed correctly or the wrong ratios of the mix are used in the concrete, you’ll likely see issues start appearing in the first 10 years of its installation.

Common Patio Problems and How to Fix Them

In many cases, problems with patios go unnoticed because homeowners actually don’t know what to look for. Here are some common problems with patios and a few solutions to help you fix them:

1. Broken or Chipped Concrete Slabs or Pavers

Concrete pavers or slabs might be incredibly durable, but they aren’t indestructible. When exposed to harsh weather changes like freezing and thawing, they can crack or break. This could also be a result of badly mixed concrete or even a weak spot on the paver caused by an impact.

Solution: To fix cracked concrete pavers and stones, you can follow these steps –

• Remove the Damaged Stone: Use a chisel and hammer to carefully remove the cracked concrete paver.
• Prepare the Base: Clear away any debris and level the base.
• Install a New Stone: Place a new stone in the prepared spot and ensure it is level with the surrounding stones. Fill in the gaps with sand or mortar as appropriate.
• Seal the Paving: Consider sealing the stones to protect against future damage.

For smaller cracks, a high-quality masonry crack filler can be used to fill and seal the cracks.

2. Dirty or Moldy Pavers

This is something that only regular maintenance can avoid. Patios exposed to the elements all year are susceptible to developing mold and discoloring.

A way to avoid this is by sealing the patio well, but in the end, sealant will wear off and get dirty. So, we’d suggest giving your patio a good clean at least once or twice a month.

3. Weeds

For homeowners who’ve used brick paving for their driveways or patios, you know the struggle against weeds, it’s an ongoing battle. Unfortunately, weeds are also an issue with patios, especially ones without roofs.

While weeds popping up between your pavers are an eye-sore, they also can pose a safety issue. This can be avoided from the beginning by using the right sand. Polymetric sand is usually used because it hardens between pavers like concrete.

When loose sand is used, it creates an easy growth path for the weeds. But with Polymetric sand, the weeds are unable to sprout.

Solution: To prevent and control weed growth –

• Manual Removal: Pull out the weeds by hand, ensuring you remove the entire root to prevent regrowth.
• Use Weed Killer: Apply a commercial weed killer, preferably one that is safe for pets and plants, to kill existing weeds and prevent new ones from growing.
• Re-Sand Joints: After removing the weeds, fill the joints between the stones with polymeric sand, which hardens when moistened and helps prevent weed growth.
• Seal the Patio: Sealing the patio can also create a barrier that makes it harder for weeds to take root.

4. Uneven Pavers

Uneven or loose pavers can be a result of a number of issues, with the most common being they were installed incorrectly. When patio pavers are uneven, they become a tripping hazard to homeowners.

There’s also the issue of loose pavers. This happens when they’re installed too far apart from one another. A good way to spot this is to inspect the edges of the paving. If they’re hanging over at the edge of the surface they’re placed on; then there’s a good chance that they’ve shifted.

Another cause for uneven or loose pavers could be the weight that’s applied to them. For instance, if you park your cars on pavers this could cause them to move.

The most effective solution for uneven or loose pavers is to relay the pavers correctly. For loose tiles, you may just need to get a better edge restraint for the pavers to stop them from moving.

Solution: To fix uneven stones or loose pavers –

• Lift the Stones: Use a flat tool to carefully lift the affected stones.
• Level the Base: Add or remove base material (sand or gravel) to level the area.
• Reinstall the Stones: Place the stones back and ensure they are level with the surrounding area.
• Compact and Fill Joints: Compact the base material and fill the joints with sand or mortar.

5. Pavers That Are Sinking

Pavers that are sinking are pretty easy to spot. They’ll be unlevel and often form a dip amongst the rest. Unfortunately, when this happens, it’s the most expensive situation to fix.

This is because the issue is beneath the pavers and is usually caused by the ground not being prepared well before laying them. It’s often a result of major drainage issues or constant water falling on that area.

Depending on the size of the patio, you might be able to just pull up that section, level and compress the ground properly, and relay the pavers. If not, you’d have to redo the entire job.

6. Stains and Discoloration

Patios are susceptible to stains from food, drinks, dirt, leaves, and other sources, leading to unsightly discoloration.

Solution: To clean and remove stains:

• General Cleaning: Regularly sweep and wash your patio with a garden hose or pressure washer.
• Stain Removal: For specific stains, use the following methods:
  • Oil Stains: Use a degreasing agent or dish soap and scrub with a stiff brush.
  • Rust Stains: Apply a commercial rust remover or a mixture of lemon juice and baking soda.
  • Organic Stains: Use a mixture of water and bleach (1:10 ratio) to remove stains from leaves and other organic materials.
• Seal the Surface: Sealing the patio can help protect it from future stains and make cleaning easier.

7. Moss and Algae Growth

Moss and algae can grow on shaded, damp areas of the patio, making the surface slippery and potentially damaging the stones.

Solution: To control and prevent moss and algae:

• Manual Removal: Scrub the affected area with a stiff brush and a mixture of water and bleach or vinegar.
• Chemical Treatment: Apply a commercial moss and algae remover according to the manufacturer’s instructions.
• Improve Drainage: Ensure your patio has proper drainage to reduce moisture buildup.
• Increase Sunlight Exposure: Trim back overhanging branches or move patio furniture to allow more sunlight to reach the patio.

7. Erosion of Joint Sand

Over time, the sand between paving stones can erode due to wind, rain, and regular use, leading to loose stones and weed growth.

Solution: To replenish joint sand –

• Clean the Joints: Remove any debris or old sand from the joints using a pressure washer or a stiff brush.
• Add New Sand: Pour new polymeric sand into the joints, ensuring it fills all gaps.
• Compact the Sand: Use a compactor or a tamper to compact the sand and ensure it is tightly packed.
• Wet the Sand: Lightly mist the sand with water to activate the polymer and harden the sand.

9. Drainage Issues

Poor patio drainage can lead to water pooling on your patio, causing damage to the stones and increasing the risk of moss and algae growth.

Solution: To improve drainage –

• Install a Drainage System: Add a French drain or channel drain to redirect water away from the patio.
• Slope the Patio: Ensure the patio is sloped away from the house and towards a drainage area to facilitate water runoff.
• Use Permeable Pavers: Consider using permeable pavers that allow water to pass through and reduce pooling.

What Are the Risks of Not Addressing These Issues?

Most of the issues mentioned above are progressive. If you decide to ignore them, the issue will only get worse, to the point where you will need to replace your patio, so it is best to keep on top of your patio maintenance.

As any of these issues progress, the pavers or slab might also become unsafe to use.  Sinkholes could be deeper than you think, and mold or dirt could make the paving slippery, causing you to slip. I’d suggest addressing these issues ASAP!
