Asphalt Sealcoating in Andover, MA
Andover had 36,569 residents in the 2020 Census, up from 33,201 in 2010, on about 32 square miles of Essex County. The Shawsheen River runs north through town on its 26.7-mile course to the Merrimack at Lawrence, and the Merrimack itself forms half of Andover's northern border. Interstate 93 meets Interstate 495 inside town lines, Route 28 is the main north-south road through the center, and Route 125 runs as a bypass through the woods of eastern Andover.
Older neighborhoods include Shawsheen Village, the planned community the American Woolen Company completed in the early 1920s around the junction of Main Street and Route 133, now a National Register historic district. For the winter itself, the nearest measured figures on this site are the Haverhill normals on the winter data page: 57.8 inches of snow in a normal year and five freeze-thaw months, November through March. This page covers what is particular to Andover: its soils, its wetland rules and its coal-tar status.
Sand, Stony Till, and Wetland Edges in Andover
Andover's soils change within a few hundred yards. Around the town center, the USDA soil survey maps excessively drained Hinckley loamy sand, formed in glacial meltwater deposits, next to Sudbury fine sandy loam, an outwash soil whose internal drainage is restricted by a seasonal high water table. Nearby are Woodbridge fine sandy loam, formed in lodgment till with dense material 50 to 100 centimeters down, and very stony Canton fine sandy loam on slopes as steep as 25 percent. The sand drains fast, while the till and the Sudbury ground can hold water right under a driveway. The sand-versus-till guide explains how each one fails.
Water rules matter here too. Andover enforces its own Wetlands Protection By-Law on top of the state Wetlands Protection Act, and town guidance lets small projects in the 100-foot wetland buffer zone file a Request for Determination of Applicability with a sketch, as long as they are not within 200 feet of a perennial stream. With the Shawsheen, the Merrimack and ponds such as Haggetts, Pomps and Fosters in town, it is worth knowing where the nearest resource area is before any exterior work. For sealing, that argues for dry-weather work, sealer kept off lawns and catch basins, and a product that raises no questions near water.

Andover FAQs
Is coal-tar sealer restricted in Andover?
Not townwide. A search of the Town of Andover's code finds no rule on coal-tar or other pavement sealants. However, a July 2016 Minnesota Pollution Control Agency tally of coal-tar actions lists Andover wetlands among the Massachusetts areas with restricted use, alongside a townwide ban in Westwood. An owner whose driveway sits in or near the 100-foot wetland buffer should ask the town's Conservation Division before any coal-tar product goes down. Asphalt emulsion sealer sidesteps the question entirely.
Which Andover driveways need edge repair first and which need drainage work?
It depends on the soil underneath. On the Hinckley sands mapped around the town center, water drains away quickly, but loose sand gives the pavement edge little support, so shoulders crack and crumble first. On Woodbridge till, dense material 50 to 100 centimeters down slows drainage, and water that gets under the asphalt freezes there, lifting and cracking the surface. One practical test: an hour after a steady rain, a sand-side drive is damp but draining, while a till-side drive still holds puddles.
How late in the year can an Andover driveway still be sealed?
Through early October in most years. Haverhill's records, the closest on this site, put the freeze-free season at about 182 days and the practical sealing season at mid-May to early October, with freeze-thaw months running November through March. Sealer needs warm, dry days to cure, so a late-September forecast deserves close attention. If the season runs out, getting cracks filled before winter matters more than the sealer, which can wait for May.
