Asphalt Sealcoating in West Allis, WI
West Allis grew around industry. Allis-Chalmers built a large new plant here in 1902, the Village of West Allis followed, and it became a city in 1906. Today 60,325 people live on 11.38 square miles, about 5,300 per square mile, which makes it much denser than Wauwatosa or Greenfield. The housing reflects that history: a median build year of 1956, with about 26 percent of homes from before 1940 and 22 percent from the 1950s, according to Census estimates for 2019-2023.
The practical effect of that density is small drives set close to buildings. With 29,015 housing units counted in 2020 on those 11.38 square miles, a drive can sit within a few steps of a foundation, a garage and the neighbor's pavement, so masking and hand-brushing make up much of the labor in driveway sealcoating, and small-job minimums matter more than square footage. Wisconsin State Fair Park and the Milwaukee Mile both sit inside the city limits, a reminder of how much of West Allis was built for industry and crowds rather than big lots.

Rules and hazards for West Allis asphalt
West Allis rewrote its coal-tar rule in 2025. Ordinance O-2025-0028 recreated section 7.19 of the city code, which bans applying, selling or contracting for coal-tar sealer or any sealer above 0.1 percent PAH by weight anywhere in the city, with forfeitures and possible jail time for violations and research exemptions granted by the health commissioner. That limit is ten times tighter than Milwaukee's 1 percent line, so a product that is legal on the Milwaukee side of the city limit may not be legal here. Ask to see the label and data sheet.
Water did real damage in 2025. During the August 9-10 storm, gauges in West Allis recorded close to 9 inches of rain, flooding in the city submerged residents' cars, and the last day of the Wisconsin State Fair was canceled. Drives that sat under water deserve a close look before sealing: soft spots, dropped edges and new cracks at the garage slab point to a base that softened or washed out. In winter, a declared snow emergency brings alternate-side parking by date from midnight to 3 p.m. and a ban on parking along major emergency routes.

West Allis FAQs
Can a West Allis contractor use a sealer that is legal in Milwaukee?
Not necessarily. Milwaukee's ordinance allows pavement sealers up to 1 percent PAH by weight, while West Allis section 7.19 bans anything above 0.1 percent, and it reaches the person who applies it, the seller and whoever contracts for the job. Asphalt emulsion, latex and acrylic products made without coal tar are the usual choices. Get the product name in writing and match it to the manufacturer's data sheet before the crew opens a pail.
What should be checked on a West Allis driveway after the 2025 flood?
Walk it after a dry week. Tap along the edges and near the garage for hollow sounds, look for cracks that opened after August 2025, and watch for dips that now hold water. A drive that was submerged can lose fine material from its base even when the surface looks unchanged. Soft areas are cut out and patched before any coat goes on, because a seal coat over a wet, weakened base tends to crack through by spring.
How much of a West Allis sealing bid is preparation?
On compact lots, most of it. With about 5,300 residents per square mile, drives here sit close to foundations, garages and neighboring pavement, all of which must be protected. The crew blows the surface clean, edges the grass, primes oil spots, fills cracks and masks brick and concrete before any sealer goes down. Small drives also hit minimum charges, so a short West Allis drive can cost nearly as much as a longer one elsewhere.
