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.

Professional installers often include a deep layer of crushed gravel under permeable pavers to allow more runoff to soak through into the soil below. Many installations will include multiple layers of gravel, with coarser aggregate at the base and finer aggregate that sits on top of that bottom layer. Above the gravel, you’ll often find coarse sand that helps reduce paver shifting over time. Some permeable paver designs include a water collection system set into the gravel layer to route runoff to a safe area for disposal.

While paving a driveway is possible to do as a DIY project, we don’t recommend it. Hiring a driveway professional to pave it will ensure that your driveway looks neat and clean and lasts for years to come, and it will also prevent a weak driveway and, potentially, damage to your foundation. Paving a driveway requires heavy machinery, and while you can rent the equipment needed, operating it close to your garage slab or around your home’s foundation can crack it and lead to structural issues. 

Yes, a paved or repaved driveway can boost your home's value by increasing its curb appeal and the functionality of your outdoor space. A new driveway can add anywhere from $5,000 to $20,000 to a property's value. An old, crumbling driveway can be a red flag for potential buyers and inspectors.

The amount of value added depends on the materials used, the design, and local market conditions. Concrete is often cited as adding the most value due to its long lifespan, though asphalt may be more desirable in colder climates. The return on investment is greatest when replacing a driveway that is in poor condition; repaving a driveway that is already in good shape will not yield as significant an increase in value.
