Questions
Helpful Answers Before an Estimate.
Should exterior drainage be corrected first?
Often, roof runoff and negative grades should be addressed as part of the diagnosis, even when interior collection is also needed.
Does drainage include crawlspace encapsulation?
Not automatically. Drainage, vapor control, insulation, ventilation, and encapsulation are distinct scopes that must be defined separately.
Can a crawlspace drain use gravity?
Only when elevations and a suitable outlet allow it; otherwise a coordinated sump system may be required.
