Whether it's worth it to install a heated driveway depends on how often you'll use it, your lifestyle, and your budget. If you live in a mild climate with little snowfall, then installing a built-in heated driveway system may not be worth it. If you live in a region that experiences mild snowfall, then a portable mat could work better. However, if you live in a region with heavy snowfall, it makes sense to invest in a built-in heated driveway. 

Whether you decide to DIY paver installation or want to hire a pro, it’s smart to understand the process. First, you’ll need to prepare the area by clearing away grass and dirt. Next, you’ll add the paver base of gravel and sand before laying the pavers on top. You may need to cut pavers to fit your space or the landscaping design and add edging stones.

Heated driveways cost an average of $12 to $25 per square foot. Depending on the size of your driveway, you may pay between $3,500 to $25,000 in total. Several factors can affect your bottom line, including material, labor, and system types. Investing in a heated driveway can save on snow removal costs because it will automatically melt the snow that falls on your driveway.

Yes, it is possible to pave over an existing driveway, but whether it's the right choice depends on several factors. If the underlying structure of your current driveway is still strong, concrete or asphalt resurfacing can be a cost-effective way to prolong its life. However, if your driveway has significant issues like potholes, deep cracks, or other inconsistencies, it is best to remove the old driveway and start from scratch. Key factors to consider include the current driveway's condition, the compatibility of the new material, the added thickness and height, and the necessary surface preparation.
