Kensington's own history traces the town to an 1689 land grant called Joseph's Park, land that later passed through several owners before the railroad era began. That same history says developer Brainard Warner began buying land in 1890 to build a garden suburb modeled on Kensington, England, and that the town was incorporated in 1894 under that name. Houses built during that Victorian-era boom sit close to Rock Creek Hills homes from a later period, so construction details vary block by block across town.
Near the historic train station or downtown Kensington, identify cellar access, additions and any changes made to a Victorian-era house's original floor plan. In Rock Creek Hills or Parkwood, describe crawlspace access and grading toward the park or a nearby stream. In Homewood or Chevy Chase View, bring details on additions, garages and basement finishing on a larger lot. A concealed connection between an older section and a later addition is worth describing wherever your Kensington house falls in that timeline, along with any recent repair invoices.
Local background: Town of Kensington: history.

01
A house built during Kensington's early development often carries a rear addition from a noticeably different period. Identify which part of the structure is original and describe the roofline where the two sections actually meet, along with any known repair history there.
02
A crawlspace on a lot that slopes toward the park can hold more moisture than one on level ground nearby. Describe access points, ground cover and how quickly standing water drains away after a typical rain, especially during the wetter spring months.
03
A detached garage or workshop on a larger Kensington lot may have its own roof and foundation, separate from the house. Describe its condition and whether a concern is limited to the main house or extends to this separate structure and its own roofline.
Where we test in Kensington, and what to tell us
Kensington Heights and Homewood
For a house mixing older and newer construction, identify which section came first and where a stain sits relative to that boundary. Describe any addition's roofline separately from the original structure.
Rock Creek Hills and Parkwood
Near Rock Creek Park, describe crawlspace access, grading toward the park and any history of a damp lower level after storms. Note the lot's slope relative to the creek and how close the foundation sits to the tree line.
Chevy Chase View
On a larger lot here, identify garage conversions, additions and basement finishing completed after the original construction. Bring whatever permit records exist for that work, including any contractor invoices or approval dates on file.
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.

Describe which section is original and where the concern appears relative to the addition's roofline. Mold Plus combines sampling of one defined area with a moisture and thermal evaluation, Mold Basic covers that same single area without the added evaluation, and Walk & Talk remains available as a consultation on its own. Share what you have noticed so the visit can be scoped around it.
A standard visit does not usually require opening walls or disturbing historic trim or plaster. Describe any delicate finishes or areas you would prefer stay untouched when booking, and the technician can explain what a non-invasive assessment can address at your specific address well beforehand.
Note how much water appears, how long it takes to drain and whether it follows a specific storm pattern you have noticed. Photographs from past years help establish a timeline. That record gives the technician useful context ahead of the crawlspace visit itself and its scope.
Yes, describe the structure and whether it shares any concern with the main house or a separate one entirely. A detached building can be added to the agreed scope, and its results will be reported separately from the main residence's findings and any samples taken there.
