Haymarket's own history page dates its charter to 1799, when William Skinker laid out the town on a plan of 140 lots and 13 streets. Federal troops burned the town on November 4, 1862, leaving only a handful of buildings standing, according to that same account, and the town incorporated again in 1882. Almost nothing built before that fire survives, so the town's older-looking core and its newer subdivisions are closer in construction age than they might first appear.
In Dominion Valley Country Club or Piedmont, describe whether your lot backs to the golf course or a conservation easement, since irrigation and natural drainage there can affect grading near the house. For a Villages of Piedmont home near open space, note any wooded buffer close to the roofline. In Glenkirk Estates or Westmarket, identify whether the house sits on a slab, crawlspace or basement, and describe any clubhouse-area amenity near your lot that might affect surface drainage. Because so little of Haymarket predates 1862, treat construction age as something to confirm rather than assume from the town's historic appearance.
Local background: Town of Haymarket: historical information.
01
A basement in one of the newer subdivisions may rely on a sump pit and pump to manage groundwater around the foundation. Describe how often the pump runs, whether it has ever failed or lost power during a storm, and where any staining sits relative to the pit.
02
A home backing to the course in Dominion Valley or Piedmont can sit near irrigation systems and drainage designed to protect the fairway rather than the house. Describe which side of the property faces the course and whether water pools there after watering or rain.
03
Villages of Piedmont homes near preserved open space can sit close to a wooded slope that sheds water toward or away from the foundation depending on grading. Describe the distance from your house to the tree line and whether leaves and debris collect near a specific wall.
Where we test in Haymarket, and what to tell us
Dominion Valley Country Club, Piedmont
These gated communities include single-family homes, townhouses and golf villas built around a shared course. Describe whether your lot backs to the fairway or a pond, identify the foundation type, and note any irrigation or cart-path drainage near the house.
Villages of Piedmont
Homes here sit close to conservation areas and wooded buffers. Describe how near the tree line comes to your roofline and gutters, identify your foundation type, and note whether a wooded slope drains toward or away from the house.
Glenkirk Estates, Westmarket
Both neighborhoods offer newer single-family homes and townhouses near shared clubhouse amenities. Identify whether your address has a slab, crawlspace or basement, describe any shared wall if applicable, and note grading changes made since the property was purchased.
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.
Virginia's residential disclosure statement advises buyers to exercise due diligence, including considering a mold assessment conducted by a business following EPA guidance. Confirm the scope and timing with your agent before settlement. A laboratory sample documents a selected place and time; it does not certify an entire home as mold-free or replace advice about your transaction.
Va. Code section 55.1-703. Current as of September 2026. General information, not legal advice.
Let the office know exactly where the stain is and roughly how long it has been there. If you are unsure whether you need lab results at all, Walk & Talk is a walkthrough conversation with no sampling. Mold Basic can sample that specific spot, and Mold Plus brings a moisture and thermal evaluation of that same spot.
Not a different type of visit, but useful context. Describe whether your lot backs to the fairway and whether irrigation or drainage from the course reaches your yard. The technician can factor that into where to look first without assuming the golf course is the source.
Not necessarily. The town's own history notes that an 1862 fire destroyed nearly every building except a church and a few houses. A home that looks historic may still be a later reconstruction or a newer build in an older style. Confirm your house's actual age before assuming its construction matches its appearance.
Yes. Describe how close the tree line sits to your house and whether leaves or debris collect against a particular wall or gutter section. Wooded buffers can hold moisture longer than open yards, so that detail helps the technician understand drainage patterns before the visit begins.
