"Protective Coatings did an excellent job sealcoating my driveway and large parking area. They were very thorough and professional. James McDonald, the owner of the company, dropped by to make sure everything went well. We had a nice chat about the industry and I told him that I would be calling them again when I needed the driveway sealcoated again. Highly recommend!!!"

"Isaac the owner, very knowledgeable of our needs to resurface our blacktop driveway. He fixed our cracks beautifully. And then put an oil base sealer on top that brought our driveway back to looking new. I would highly recommend using him very easy to work with. And the price was extremely reasonable."

"I would have given them a 5 star rating but I had a few spots get messed up on my drive way where you can tell it was thinner. When I asked about them fixing it he said he didn’t do small jobs. I asked for Johnny to come out and look at it he said he would. It’s been weeks now and he won’t he hasn’t came out like promised. Johnny won’t even answer my phone calls. I’m very disappointed that this is how they are treating a customer. It shouldn’t matter if it’s a big job or a little one. If you can tell in the picture that was sent that the asphalt was thinner in a spot you should guarantee your work and come fit it. I even said if I have to pay I will since I did have workers out to take out a tree and their truck was what caused damage. But Johnny even agreed that sometimes the machine can give out a thinner layer like what was caused in this situation so why won’t he come fix it? So I would go else where to get your asphalt done. My neighbor got his done as well so I’m including the whole price since since it’s all tied together bc our driveways join together."

"Outstanding! Mike showed up to bid the job right after phoning him. He gave a fast simple estimate and we hired him. On the spot. He said he would have a crew here by 8:30 and and finish the 200 yd driveway in one day. The guys pulled in @8:30 am, 4:30 they were done and it looks fantastic. Supremely satisfied."

Driveway Sealcoating FAQs, answered by experts

It depends on the type of sealer. Some sealers can dry in as little as 4 hours, but many can take up to 48 hours to fully cure. To play it safe, don’t drive on your driveway for two days after sealing.

Maintaining a driveway depends on its material. For concrete and asphalt, it's best to clean the surface thoroughly twice a year with a stiff broom and a pressure washer to remove accumulated dirt and debris. Sealing the driveway is crucial to protect it from water damage and freeze-thaw cycles. Before applying a sealant, pressure wash the surface to remove any loose sealant, dirt, or stains, as sealing over them will trap them. Any cracks or expansion joints should be filled with a flexible polyurethane caulk or asphalt sealer. In colder climates, use sand instead of salt for de-icing. Sand helps melt snow and ice without accelerating the freeze-thaw process, which can cause cracks.

Oil can permanently stain a concrete driveway if it fully dries or sits for weeks without cleaning. Concrete is porous and absorbs the oil deeper over time. That’s why it’s best to remove an oil stain when it’s wet by applying an absorbent material, sweeping the area, applying dish soap, scrubbing, and then rinsing.

Sealing your driveway gives it the longest possible lifespan. You’ll reduce your driveway’s risk of cracking, breaking down from exposure to UV light, discoloring, and staining from road chemicals.

What causes driveways to crack can vary by driveway material. Sealcoating with the right formula creates a protective "shell" over a driveway. Resealing a driveway on schedule helps to preserve its lifespan substantially by keeping it protected against damage from UV rays, motor oil, chemicals, hail, rain, snow, and more. If you don't reseal your driveway, this will lead to brittleness, cracking, and potholes that can eventually cause your driveway to fall apart.
