Replacing a driveway is a significant home improvement project that typically occurs every 20 to 25 years. While the process involves heavy machinery and professional labor, it also presents the single best opportunity to install a radiant snow melting system. By integrating heating cables or mats during the replacement process, you can eliminate the need for shoveling, salt, and snow blowers for decades to come.
Quick Facts: Driveway Replacement
- Timeline: A full replacement typically takes 1–4 weeks depending on the material.
- Best Time: Installation is most cost-effective during the "Sub-Grade" or "Paving" steps.
- Longevity: A well-installed driveway with radiant heat can last 30–50 years.
- ROI: Heated driveways increase home value and prevent salt-related surface damage.
Step 1: Demolition and Removal
The first step in replacing a driveway is the demolition of the existing surface. Whether you have cracked concrete or crumbling asphalt, a contractor will use heavy equipment like a jackhammer or a skid-steer loader to break up the old material. This debris is then hauled away for recycling or disposal, leaving a clean slate for your new installation.
Step 2: Excavation and Grading
Once the old surface is gone, the soil underneath must be excavated to the proper depth. This step is critical for ensuring proper drainage and a stable foundation. The contractor will grade the area to ensure water flows away from your home's foundation. If you are planning to install a snow melting system, this is when the initial electrical conduit should be planned and positioned.
Step 3: Sub-Grade Preparation
The sub-grade is the foundation of your driveway. It usually consists of a layer of crushed stone or gravel that is compacted to provide a stable base. Proper compaction prevents the driveway from settling or shifting over time. For heated driveways, this base must be perfectly level to ensure the heating elements are embedded at a consistent depth.
Step 4: Paving and Snow Melting Installation
This is the final and most exciting step. Depending on your chosen material—asphalt, concrete, or pavers—the installation process for the snow melting system will vary slightly:
- Asphalt: Heating mats are installed specifically between the base and primer coat.
- Concrete: The heating system must be installed with 2–3” of concrete both above and below.
- Pavers: The system is installed directly beneath pavers and covered with finished mortar or sand.
Once the surface is laid, a licensed electrician will connect the system to a dedicated controller, such as the SCP-120, which uses sensors to automatically activate the heat when snow or ice is detected.

Frequently Asked Questions
Can I retrofit a snow melting system to my existing concrete or asphalt driveway?
Yes, you can retrofit a snow melting system into a preexisting driveway made of concrete or asphalt. You can do this by using an appropriate tool to cut properly spaced lines (or trenches for tire tracks heating) in the surface. Then you can place the the heating elements in the lines (or trenches) before sealing them with either hot asphaltic sealer for asphalt retrofits, or backer rod and expansion joint sealer (SikaFlex or similar) for concrete retrofits. Of course, you'll want to make sure this step is done in accordance with the filler manufacturer’s recommended procedures. Check out our snow melting retrofit guide for more information about this process.
What maintenance is required for heated driveways?
Heated driveways are practically maintenance-free. Below the surface of your driveway, the heated cable is perfectly safe and the electrical components last for many years with little to no maintenance requirements.
How much does it cost to run a snow melting system?
Operating costs are minimal: Snow melting systems typically cost just $0.12–$0.60 per hour to run, depending on system size and local electricity rates. For a typical 6-hour snow event: $0.72–$3.60 per storm. Annual cost estimate (assuming 10 snow events): $7.20–$36 per year.
