Commercial floors, moisture control and demolition in Chesterfield, Missouri

Is Chesterfield, Missouri, an old-home asbestos market?

No, and this page does not pretend it is. Only 14.4% of Chesterfield homes were built before 1970, and 46.3% before 1980. The largest age group is the 1970s, with 6,895 of 21,603 housing units. That makes commercial floors and moisture control the main fit for this page. It does not make any single home safe to disturb: nearly half were built before 1980.

Asbestos still matters in any building with older materials, whether a home before a remodel or a commercial building before a tenant buildout or demolition. Test suspect materials before you disturb them. Our asbestos survey service covers that step before demolition or renovation.

A name note. Chesterfield also exists in Virginia, New Jersey and the United Kingdom. This page covers Chesterfield in St. Louis County, Missouri.

What is the Chesterfield Valley, and why does it matter for floors?

The Valley is a large community inside the city limits, and a levee protects it. The city says more than 4,500 acres of levee-protected area lie in the Chesterfield Valley, protected from Missouri River high water by the Monarch-Chesterfield levee. A levee protects land. It does not describe any one slab.

We do not publish moisture readings for the Valley. Nobody has given us a source that does. Treat moisture as a slab-by-slab test. A past flood or a levee rating tells you about the river, not about vapor coming up through a floor. A moisture test on your own slab answers that, and it should come before any coating or polish is priced.

Do I need a floodplain permit for floor work in Chesterfield?

Check before you assume. The city says a Floodplain Development Permit is required before construction or development begins within any special flood hazard area or supplemental protection area. Coating a floor inside an existing building may not count as development, and we did not confirm that either way.

So ask the city’s floodplain staff about your parcel, in writing if you can. It costs a phone call and can save a stalled job. Occupancy is a second check: a tenant move-in needs an inspection by the City of Chesterfield and St. Louis County.

How do I protect a commercial floor from moisture in Chesterfield?

Test the slab first, then pick the system. Moisture can rise through concrete and lift coatings, stain flooring and feed mold. A liquid barrier goes down before the finish. AES describes its moisture barrier as a liquid applied before flooring “to prevent moisture from penetrating the flooring,” which can head off mold growth later.

Read the moisture barriers page and the moisture barrier glossary entry. If a space has already taken on water, see fire and water restoration and mold inspection. For a first read on mold size, see our post on mold over 10 square feet.

Slab prep is the other half. Concrete grinding opens the surface so a coating bonds. Our concrete floor prep guide explains the order of work.

Which floor system fits a Chesterfield warehouse, showroom or office?

Pick by traffic and look. AES says its epoxy coating “can be applied over new or old concrete floors” and is great for commercial and industrial buildings, including factories, warehouses and manufacturing plants. Polished concrete suits showrooms and offices where you want a clean, hard look.

• Warehouse or shop: epoxy floor coatings. See the epoxy floor coating entry.
• Showroom or office: concrete polishing and commercial concrete polishing. See polished concrete.
• Not sure: read polished concrete vs epoxy.

AES quotes each floor after it sees the slab, because cracks, old adhesive and moisture change the plan.

What about demolition in Chesterfield, Missouri?

We could not confirm a separate City of Chesterfield demolition permit rule, so call the city before you hire a crew. The County rule is clear. Every municipality relies on the St. Louis County Department of Public Health Air Pollution Control Program to ensure that asbestos and other hazards are addressed before a demolition permit issues.

Each structure must be inspected for asbestos-containing material by a Missouri licensed asbestos inspector, and County inspectors visit demolitions to keep dust on the property. Missouri DNR sets a state notice as well. Our Missouri demolition and renovation asbestos rules guide covers that sequence. For the work itself, see demolition and interior demolition.

How far is AES from Chesterfield?

About 21.7 miles, roughly 31 minutes without traffic, from our office at 3100 Gravois Ave in St. Louis to the Chesterfield city hall. That is an OSRM free-flow estimate, so allow more at rush hour. AES takes projects within 300 miles of St. Louis.
