How we found builders. We searched Google Maps for custom and luxury home builders across Fairfax County and Arlington (October 16, 2026), then Loudoun County and Montgomery County, Maryland (October 17, 2026), and reviewed about 450 results. We kept firms that build new custom homes in the towns we cover. We left out production builders who sell homes in their own communities, firms that only remodel, and businesses we couldn’t confirm are active.
What we check. Every fact on a profile comes from the builder’s own website or a public profile we link (Houzz, NewHomeSource, Business View Magazine, the Maryland Building Industry Association, Bethesda Magazine, Northern Virginia Magazine). Prices appear only when the builder publishes them. Google ratings and review counts are what Google Maps showed on the date shown on each profile.
What we don’t do. We don’t rank builders, write reviews, or copy reviews from other sites. Lists are alphabetical. “Builds on your lot” means the builder says so on its website; “Ask” means it builds custom homes but doesn’t say.
Town pages list builders that name the town, or its whole county, as a service area. Permit facts come from the official pages of Fairfax, Arlington, Loudoun and Montgomery counties and the towns and cities we cover, linked on each page.
Architects are listed the same way: facts from their own profiles, alphabetical, no ranking.
Photos on builder profiles are sent in by the builders themselves, who confirm they have the right to share them. We approve each one before it appears and never show street addresses.
Real build costs come from homeowners who report what they paid. We show figures only once at least 5 reports exist for a group, and never show individual reports.
Building permit data. We looked for public permit records that name the builder. Fairfax County’s permit map service needs a login token and Arlington’s permit data blocks automated access, so we don’t show permit counts yet.
Verified builder details. Builders can add availability, pricing, warranty and a short note through this form. We publish it only after checking the sender’s email matches the company’s website domain, label it as supplied by the builder, and date it. It never replaces the sourced facts.
Homeowner stories and questions. Stories, notes and questions come from readers. We read every one before it appears, confirm story authors by email, and don’t pay for stories. A story a builder invited is labeled that way.
Lot checker. The lot checker reads official public data live: the U.S. Census Bureau geocoder for the county and town, FEMA’s National Flood Hazard Layer, Fairfax County’s Approved Sewer Service Area map and Montgomery County’s water and sewer categories.
Corrections. Builders and readers can send corrections through this form. We check them against a source before changing anything.
