When Concrete is either new or old and tired it is a smart move to have it sealed. It will not only keep the area well presented but it will also preserve the surface and make it much easier to clean and maintain.
Depending on the area your concrete is in around your property whether residential or commercial we have various seal options to suit your needs.
Due to the non-VOC laws in California, the sealers that are available have approximately a 1-2 year life. So if your existing concrete was sealed more than 2 years ago, it has most likely broken down and is in need of being replaced.
