Asphalt questions St. Petersburg homeowners ask
- How much does an asphalt driveway cost in St. Petersburg?
- At the local average of about $5.14 per square foot installed, a 20×40 ft (800 sq ft) asphalt driveway runs $4,112. Quotes typically land between $2,352 and $5,488 depending on base condition and whether old pavement must come out.
- What does asphalt cost per square foot in St. Petersburg?
- Resurfacing over a sound existing base runs about $2.94–$4.9 per square foot in the St. Petersburg market; a full new build with excavation and a compacted gravel base runs $4.9–$6.86. Tear-out of an old driveway adds $0.98–$2.94.
- Is asphalt or concrete cheaper in St. Petersburg?
- Asphalt installs for $2.94–$6.86 per square foot versus $5.88–$9.8 for concrete, so it wins upfront. The trade-off is upkeep: asphalt wants sealcoating every 2–4 years and lasts 15–25 years, while concrete commonly runs 30-plus.
- Do I need a permit to pave a driveway in St. Petersburg?
- Usually yes when the driveway meets a public street or sidewalk — the apron is in the right-of-way. Check with the St. Petersburg building department; many contractors pull the permit as part of the job.
- How long does an asphalt driveway last in St. Petersburg?
- 15–25 years with a proper base and regular sealcoating. Drainage decides which end of that range you get: water standing on or under the mat is what kills asphalt, so keep a 2% slope and seal cracks yearly.
- Should I resurface or fully replace?
- If the base is sound and less than about a third of the surface is cracked, a 1.5–2 inch overlay at $1.96–$3.43 per square foot buys another decade. Widespread alligator cracking or soft spots mean the base has failed — overlaying it just resurfaces the problem.
