Potomac, MD water damage decisions, explained from dated public records.

This resource explains water damage decisions in Potomac, MD from public records, each with the date it was checked.

We cover what happens after water enters a Potomac home: cleanup, drying, repairs, permits, and the coverage questions around them. Independent restoration companies that serve Potomac, MD price and perform the work, and this site holds no license or certification of its own.

We list the permit office and utility for each area, and we tell you what to check before you sign. Where a rule is not verified, the page tells you to check with the office.

How These Pages Are Sourced

Each fact here starts as an entry in a research log with the publisher, the document, the supporting quote, and the check date. Only entries marked confirmed reach a page, and the source note below links to the full list of documents.

We rely on government offices such as DPS and FEMA, standards bodies such as the IICRC, and insurance research such as Triple-I. Figures appear as the record states them, so the Potomac basement share keeps its limit on condominiums.

We leave out what we did not read. WSSC Water's own pages were not readable in our checks, so line ownership rests on the county plan and Maryland Public Utilities 23-202. Insurance rules rest on the Insurance Article, COMAR 31.15.07, FEMA, and Triple-I.

We read the IICRC's S500 page, its 2026 position statement, and a 2015 summary, not the full standard. So no page here credits S500 with a meter, camera, or drying goal rule. Trade groups and equipment makers appear by name where no agency speaks.

What a Good Cleanup Looks Like

A good cleanup in a Potomac lower level leaves you with records, and the IICRC S500 5th edition is the standard in force. Look for a restoration company that meets these 6 marks in its work and paperwork, and water damage restoration explains the full process.

The same marks apply to water in basement cleanup, water heater leak cleanup, toilet overflow cleanup, and sump pump failure water cleanup.

Inspects the source before setting the water category, as the IICRC says the restorer does.
Uses contamination controls and remediates before restorative drying on Category 2 or 3 water, per the IICRC.
Aims at the US EPA drying window of 24 to 48 hours to prevent mold growth in most cases.
Keeps a drying log of daily readings, as NFIP's claims manual describes, so you can see water extraction and drying on paper.
Leaves the electrical check to an electrician when a main switch sat in standing water, as CDC says.
Names who obtains the DPS restore/repair permit for your repairs.

How to Check a Restoration Company Before You Sign

You can check a Potomac restoration company with 2 public lookups and the paperwork it gives you.

The county Office of Consumer Protection says all home improvement contractors in Maryland must hold a Maryland Home Improvement Commission license. The commission's License Search checks a contractor or salesperson. This site found no MHIC statement on extraction and drying alone, so check with MHIC on that scope.

The IICRC Global Locator lets you verify an IICRC Certified Firm and its technicians, and the IICRC also lists invalid firms. A Certified Firm needs current liability insurance and at least 1 active Certified Technician, in the IICRC's own description.

Maryland law requires a home improvement contract to be written, legible, and signed by each party. It must show the license number, dates, description, and price. A contractor cannot take more than one-third as a deposit or take payment before signing.

You can cancel a door-to-door home improvement contract in Maryland until midnight of the 5th business day, or the 7th at age 65 or older. A buyer-initiated emergency with a handwritten, signed waiver is the exception. The Maryland Attorney General's Consumer Protection Division enforces the Door-to-Door Sales Act.

The county Office of Consumer Protection warns about storm chasers and about signing an agreement to agree. Montgomery County police advise caution with unsolicited home improvement offers, especially from door-to-door salespeople.

Search the contractor's license on the MHIC License Search.
Look up the firm on the IICRC Global Locator.
Read the written estimate for the rooms, materials, and measurements behind the price.
Ask for dated moisture readings and a drying log for each wet level.
Confirm who obtains the permit and from which office.
Pay no more than the one-third deposit that MHIC names, and only after you sign.
