Montgomery Planning's historic resource page for the area describes Chevy Chase as platted in the 1890s by developer Francis Newlands, planned as what the county calls a comprehensive, ideal community with early attention to transportation, infrastructure and architectural standards. That single vision later split into separate municipalities, from Chevy Chase Village to the Town of Somerset, each governing its own streets. A house near Connecticut Avenue and one in a numbered section built later can differ in foundation type and framing even though both sit inside that same historic footprint.
Identify which Chevy Chase municipality your address falls in, since building age and permitting history can differ from one village to the next even along the same street. For a detached house, bring details on additions, garages converted to living space and any cellar or crawlspace access. In a condominium along the busier corridors, describe your floor and unit location relative to any known roof or window repairs. This page also serves the unincorporated pockets of Chevy Chase that sit outside any of the small municipal boundaries, where permitting instead runs through the county.

01
An older roof with a masonry chimney has more flashing seams than a simple roof plane. Describe where a ceiling stain sits relative to the chimney, and whether the flashing has been repaired or replaced recently.
02
A below-grade window well can collect runoff if grading or the well's own drain has changed over time. Note whether staining appears near a specific window and whether the well has been cleaned, regraded or fitted with a new cover recently.
03
A side porch or sunroom enclosed after the original construction can sit on a shallower footing than the main house and meet it at a seam that moves differently through the seasons. Describe when the room was enclosed, how it is heated, and whether staining follows that seam.
Where we test in Chevy Chase, and what to tell us
Chevy Chase Village and the Town of Chevy Chase
For a detached house in either municipality, identify the cellar or crawlspace, any rear addition and where a stain sits relative to the roofline. Local permitting records may help date the work.
Section Three, Section Five and Martin's Additions
Across these smaller villages, describe additions, enclosed porches and garage conversions separately from the original structure. Note whether the affected room was part of the first construction or added later, and describe any recent exterior repair work.
North Chevy Chase, Chevy Chase View and the Town of Somerset
In these municipalities, identify crawlspace access, well or grading details on a larger lot, and any recent exterior work. Each village handles its own permits, so bring what records you have, including any contractor estimates or invoices.
No version of your result is worth more to us than another one. If the report says you need work, you choose the remediator. A separate post-remediation assessment can document conditions after the work within its agreed scope.
For a Maryland property, define the question before ordering samples: a particular stain, persistent odor, water event or follow-up after repairs. Keep dated observations and laboratory findings with the repair history. A report does not determine health risks, insurance coverage or legal responsibility. Montgomery County also publishes separate radon requirements for covered home sales; confirm which rules apply to your transaction.
EPA sampling guidance; Montgomery County radon guidance. Current as of September 2026. General information, not legal advice.
Describe the room, how large the affected area is, and whether the concern is confined or spreads across more than one wall. Walk & Talk offers a consultation without samples, Mold Basic and Mold Plus each target one defined area, Mold Plus adding a moisture and thermal evaluation, and Mold Advanced covers a whole-home scope once concerns spread beyond one spot.
Yes. Describe your floor, unit location and any known window, roof or plumbing repairs already recorded for the building. A single-unit visit can address your own space, though a shared or building-wide source may need coordination with management before full access to common areas is possible.
It can help explain permitting and renovation history, since Chevy Chase Village, Somerset and the other municipalities each keep separate records. Tell us your specific municipality when booking, along with any known permit numbers. The technician still evaluates your individual house rather than treating nearby villages as a single building stock.
Describe which rooms are original and which were added, along with any known roofline changes at the connections between them. Starting at the reported stain or odor, with that renovation history in hand, usually gives the clearest possible agreed scope for a productive first visit.
