Get the condition documented
Note where it shows up, when it started, any connection to weather or humidity, how it's progressed, and what's already been done. A few photos and basic measurements make the first call more productive.
Read the local context
Savannah pairs historic masonry and wood-frame buildings with mid-century neighborhoods, barrier-island homes, and fast-growing inland suburbs. Coastal humidity, wind-driven rain, flood exposure, salt air, and high water tables make moisture management central.
Ask what's about to disappear behind finish work
Install method, flashing, sill condition, frame material, glazing package, trim restoration, and sun and salt exposure on that wall matter as much as the window itself. That should be spelled out in the scope before humidity and finish work hide it for good.
Weigh the full scope, not the sticker price
Look for coverage of protection, access, materials, permitting, testing, cleanup, restoration, exclusions, warranty terms, and change-order pricing.
What official local sources add
Savannah maintains separate conveyance systems for household wastewater and rainwater; the city says stormwater flows to surrounding creeks, marshes, and rivers. Its original square plan dates to 1733, while island and west-side neighborhoods require a different coastal moisture and drainage lens than the Landmark District.
Sources were reviewed June 20, 2026. Flood exposure, historic-district status, and permit requirements shift from parcel to parcel in a coastal city like this one, so confirm current rules with the City of Savannah before authorizing any work.
