You should seal asphalt driveway spaces periodically for the best results. There are many differing opinions about the frequency of the sealing. Some people say every year, while others say once every 10 years. If you are trying to determine when to seal your driveway, here are a few factors to consider.
The first thing that you need to understand that every driveway is different. Therefore, the first place that you should go for information is your individual driveway. If it looks like it is cracking and is not sealed, then you need to seal it with a good asphalt sealer. However, you will want to make sure that you do not seal a new asphalt driveway within 6 months of initially installing it. This will give the materials in the asphalt time to set up properly before being sealed.
One big factor in determining how often to seal your asphalt is the climate in which you live. If you live in a very moderate climate that never changes, you should be able to last around three to four years. If it freezes in the winter and gets over 100 in the summer, then you should seal it every one to two years.
