Q: Should I power wash my driveway before sealing it?

• <div><p>You should always power wash your driveway before applying a sealant. At any given time, your driveway could be covered with algae and moss, tire residue, oil and rust stains, and any combination of leaves, twigs, and dirt. If you skip power washing, you&rsquo;ll be trapping the dirt and grime beneath the sealant and lowering its chance of cementing itself to your driveway. While you can expect the <a href="https://www.angi.com/articles/cost-to-pressure-wash-driveway.htm">cost to pressure wash your driveway</a> to average between <b>$100</b> and <b>$350</b>, the few hundred dollars beats an unattractive driveway or paying extra to reapply your driveway sealer.</p></div>

Q: Should I seal asphalt before it’s fully cured?

• <div><p>Yes, you can seal asphalt before it&rsquo;s fully cured but you should wait to do so until at least three months after installing it. Otherwise, the seal coat can trap the asphalt&rsquo;s oils and chemicals, preventing it from fully hardening. This can lead to a weaker surface that&rsquo;s vulnerable to damage. But if you wait at least three months, applying a seal coat can extend its life by protecting it from water, UV rays, and other damaging elements.</p></div>

Q: Should I seal my driveway or replace it?

• <div><p>If you notice minor cosmetic problems with your driveway, you should seal it. Look out for cracks and holes on the surface, faded asphalt or concrete, and stains from oil and other chemicals. Replacing your driveway may be necessary if you&rsquo;re dealing with significant problems&mdash;&frac14;-inch cracks, large potholes, and puddles from drainage issues. The <a href="https://www.angi.com/articles/how-much-does-it-cost-install-asphalt-driveway.htm">cost to install an asphalt driveway</a> typically ranges between <b>$4,200</b> and <b>$9,000</b>, significantly more than resealing. Consider talking to a professional to discuss whether resurfacing your driveway&mdash;a midway project between resealing and replacing&mdash;is a better option for you.</p></div>

Q: How do you maintain a driveway?

• <div><p>Maintaining a driveway depends on the material your driveway is made of. Concrete and asphalt should be sealed to protect against water and freeze-thaw cycles. Cracks and expansion joints should be filled with a flexible polyurethane caulk or asphalt sealer. Before you apply a sealant to your driveway, consider pressure washing the surface. It will take off any loose sealant and any grime that might have caused a stain. Sealing over dirt and stains will trap it under the sealer.</p><p>If you live in colder climates, consider using sand rather than salt to de-ice. Sand helps melt the snow and ice without speeding up the freezing and unthawing process of your driveway, which helps prevent cracks from forming from the constant fluctuation of temperatures.</p></div>

Q: What is the most eco-friendly driveway sealer?

• <div><p>In general, water-based driveway sealers are considered the most eco-friendly option. Products that utilize water, limestone, and some basic binding agents have lower VOC levels and odor levels compared to sealants made with oil or tar. In recent years, soy-based driveway sealers have become available for homeowners who want fully VOC-free driveway sealers.</p></div>

It took about week to complete. Sanso left allowed me to break up the old sidewalk and knocked off 200 dollars on the price. They even added a french drain to my driveway to help with rain run off. The new sidewalk and driveway looks great. I would use them again.
