If you value something, you should take care of it. It is true for your house, your car and even your driveway. Regular maintenance can save you a lot of money in the long run.

Concrete that is subject to freeze-thaw cycles should always be sealed. This means if you live in the Pittsburgh area, sealing your concrete is a must. Sealers form a protective layer on the concrete surface, creating a hard, long-lasting abrasion and chemical resistance.

Concrete driveways are often the biggest victims of unsightly stains. Parked cars that are steadily leaking oil often cause stains. Because people often park their vehicles in the same spot, a stain can grow into something much more noticeable over time.

A sealer acts as a barrier between the concrete’s pores and the environment. When oil leaks, it sits on the surface of this barrier, rather than absorbing into the concrete. A quick spray with a gardening hose can usually take care of spills and dirt in a few moments, making maintenance much easier and more effective. The ability to prevent stains can keep your concrete looking new much longer.

What happens if I don’t seal my concrete?

Concrete is a porous material that readily absorbs liquids. In freeze-thaw climates, the expansion of frozen liquids can destroy the surface of unsealed concrete. Salt, oil, gas, and other household chemicals can discolor and damage unsealed concrete.

Un-sealed concrete can also lead to moisture that does not dry out. This can lead to the formation of mold and mildew. This may cause the appearance of green discolorations on the concrete surface. When you seal your concrete, you inhibit the growth of mold. This will help to protect the concrete and makes it look better for a long time.

How often should I have my concrete sealed?

Homeowners should have their concrete sealed every 4 to 5 years in the spring or summer. Warmer weather allows for smooth application of the sealant, as well as better drying time.

Will sealing my concrete extend its life?

The average concrete surface can last 30 to 40 years, but if it suffers from cracks or discoloration, you will be forced to replace it earlier than planned. Bottom line – Sealing can increase the durability of concrete.


Remember, a sealer will enhance and protect your new or existing concrete. When properly sealed the service life of concrete is greatly extended.
