Wood-To-Soil Contact Review in Frederick
Wood that contacts soil gives subterranean termites a direct path into your structure without building a mud tube. A wood-to-soil contact review in Frederick identifies every location where this condition exists and documents what correction is needed.
Why Wood-To-Soil Contact Is a Primary Termite Risk Factor
Subterranean termites need to maintain contact with the soil for moisture. When structural or decorative wood contacts the soil directly, termites can access it without ever building a visible mud tube. This means the infestation may advance significantly before any above-ground sign is detectable. Wood-to-soil contact is identified on NPMA-33 WDI reports as a condition conducive to infestation because it is one of the most reliable predictors of termite risk.
Common wood-to-soil contact situations in Frederick homes include: deck posts set directly in soil or in concrete footings with the wood extending to grade; wood stair stringers at the bottom step that rest on or near soil; exterior door frame bottoms that have settled to grade level over decades; landscape timbers, railroad ties, or garden edging placed against the house; untreated wood forms left in place under concrete during construction; and original wood framing in older homes where the grade has risen over time due to soil settlement or added landscaping.
Some wood-to-soil contact can be corrected by raising wood above grade with metal standoffs, cutting back encroaching soil, or replacing wood members with pressure-treated lumber or composite materials. Others may require more significant work. Our review gives you a complete inventory of all contact locations and a practical assessment of what correction each situation requires.

Common Questions About Wood-To-Soil Contact Reviews
Does pressure-treated wood prevent termite infestation at soil contact points?
Modern ACQ or CA pressure-treated lumber is rated for ground contact and provides significant resistance to termites and rot. However, "resistant" does not mean "immune" — older pressure-treated lumber with chromated copper arsenate (CCA) that has weathered significantly may have depleted protection. The soil contact point is still worth inspecting even when pressure-treated wood is in use.
My deck was built with treated wood — do I still have wood-to-soil contact risk?
Post bases, ledger boards, and bottom step stringers are the most common contact points on decks even when treated wood is used. Treated posts in concrete can wick moisture, and over time, soil can accumulate around the base. We check deck framing at grade level during the review regardless of lumber treatment status.
Who repairs wood-to-soil contact problems — a pest company or a contractor?
Most corrections involve carpentry or landscaping work: cutting back grade, adding post bases, or replacing members. This is typically done by a general contractor, deck contractor, or the homeowner. The pest inspector identifies and documents what needs to change; the physical correction is usually a carpentry task rather than a pest control service.
