Yes, adding a patio or other concrete feature can increase your property taxes, particularly if it's considered a permanent improvement. The general rule is that if the project requires a permit, your property taxes will likely go up.

Permanent structures like a poured concrete patio are considered capital improvements that require a permit, which will trigger a reassessment of your property's value. Other concrete projects that typically increase taxes include:

• Pool decks

• Walkways

• Driveways

• Steps

• Foundations

In contrast, 'temporary' installations, such as a paver or flagstone patio, may not require a permit and are less likely to affect your property taxes.

Permit costs for a concrete patio can range from $75 to $200. While the tax increase varies based on your location and the project's size, it is often a minimal amount. Always contact your local building department before starting a project to confirm permit requirements and any potential impact on your taxes.

Small cracks should be filled with a flexible crack filler, like a rubberized asphalt-emulsion crack filler or a flexible masonry crack filler. Larger cracks need something a bit more solid to prevent further movement and to avoid having to use too much of the flexible filler. For concrete, you can use a concrete backer rod while asphalt can handle sand, gravel, or even dirt.

Concrete blemishes such as chipped steps or small cracks are fixable with patching. For bigger jobs, including driveway repair and cracks wider than a 1/4 of an inch, patches will only serve as a temporary fix. Resurfacing is ideal when the surface is showing more widespread wear—like if it’s pitted, rough, or has lots of cracks. Resurfacing gives your concrete a fresh, like-new appearance without needing a full replacement.

When the concrete is severely cracked, sinking, or otherwise structurally unsound, replacing it might be your best option. Replacement ensures the safety and longevity of the surface in this case.

No, hairline cracks in concrete are generally not a problem as they do not impact the strength and longevity of the concrete. Generally, cracks less than 0.3 millimeter wide don’t impact the structure. Hairline cracks can grow over time and weaken the structure, such as in a home foundation. Some hairline cracks can also cause leaks in a foundation. It’s important to watch the cracks to see if they grow. Contact a concrete contractor if you notice cracks exceeding 0.3 millimeter wide.
