Regular cleaning, sealing, and crack inspections help prolong the surface’s life and maintain safety.

It depends on whether you’re looking at residential or commercial buildings. For residential buildings, the 2018 International Residential Code asks for a maximum riser (or rise) height of 7 3/4 inches and a minimum tread depth (or run) of 10 inches.

For fixed stairs in commercial buildings, OSHA requires a rise between 6 and 7.5 inches, with a run between 10 and 14 inches. The standards are different for spiral staircases.

The repair method for a damaged concrete patio depends on the type of damage. For surface cracks, a concrete crack filler is a quick and simple fix. For larger cracks or uneven slabs, you may need to hire a professional to pump a cementitious material under the sunken portion to lift it back into place. For heavy spalling and other surface damage, resurfacing may be the best and most affordable option. This includes pouring a new layer of concrete over the old layer.

It’s technically possible to install your own patio, but we don’t recommend it. Installing a patio is labor- and time-intensive, and getting the end product to look professional demands patience and experience. Not only can mistakes lead to unevenness in your patio and expensive repairs, but not grading the surface properly can cause issues with water management, potentially leading to leaks in your home, foundation damage, and flooding. It’s more expensive to hire a patio company, but it’s usually well worth the investment to avoid costly mistakes.
