Termite inspection and treatment price ranges for Centreville, VA homes (market ranges; exact figure confirmed on-site)
Termite inspection cost in Centreville depends on whether a written WDI report is required
Two different inspections carry two different prices. A diagnostic inspection — a technician walking the foundation, probing the sill plate, checking the crawlspace piers and the deck ledger board — is normally free when it is done to produce a treatment quote. A WDI inspection is a paid, documented product: the inspector fills out the NPMA-33 form, notes visible evidence, notes damage, and signs it for the lender, buyer, and settlement file. That report typically falls in the $95–$200 range in Fairfax County. Buyers and lenders generally want the report dated within 30 to 90 days of settlement, so ordering it eight weeks before closing usually means paying for a second one.
Termite treatment pricing follows foundation linear footage, not house square footage
A 3,400 sq ft colonial and a 1,900 sq ft colonial can cost the same to treat if both have 180 linear feet of foundation. The technician measures the outside perimeter with a wheel, then adds interior linear footage for any slab expansion joints, bath traps, or crawlspace piers that need treating. That measurement, plus obstructions, sets the number. A Centreville townhouse interior unit often has only 40 to 80 exposed linear feet, which is why townhouse quotes land near $700–$1,400 while detached homes with wraparound decks and full-perimeter mulch beds land at $1,300–$3,000. <strong>Ask any company for the linear footage they measured — an honest termite quote can show its math.</strong>
