Insulating Homes in Georgia's First City

Spray foam insulation in Savannah starts with knowing which Savannah you live in. The city was laid out in 1733 on Yamacraw Bluff above the Savannah River, and its downtown, with 22 squares, the Historic District and the Victorian District, became a National Historic Landmark District in 1966. Around that core are early 20th century neighborhoods like Ardsley Park and Thomas Square, postwar Southside streets and newer annexed subdivisions in west Chatham. Each one insulates differently.

Housing age

Savannah's median home was built in 1971. About 16.2% of homes predate 1940, another 21.3% were built in the 1940s and 1950s, and about 14.9% went up from 2010 on, based on 2019 to 2023 census estimates. About 55.9% of housing units are detached single-family homes, and 45.4% of occupied homes are owner-occupied, so rentals are a large share of what needs insulating.

Older homes

In houses from before the war, walls are often plaster over open stud bays with no insulation, attics hold a few inches of old fill, and floors sit over brick piers or vented crawl spaces. Foam in the walls usually waits for a renovation, when the bays are open. The quickest wins are sealing and topping up the attic and fixing the floor from below. Historic district rules focus on what you see from the street, but if your project touches the exterior, check with the city's preservation staff first.

Climate

Savannah is humid subtropical. July highs average about 92.3°F, August humidity averages 78.6%, and the city gets about 48 inches of rain a year, with June the wettest month at about 6.65 inches. Winters are short, with about 21 nights below freezing in an average year. Air conditioning runs for most of the year, so air leaks cost money in nearly every month.

Storms and low ground

The city sits just above sea level and has a history of flooding from heavy rain and hurricane surge. Matthew in 2016, Irma in 2017 and Debby and Helene in 2024 all hit the area. In flood-prone spots, closed-cell foam is the only spray foam FEMA rates acceptable below flood elevation, and wet crawl spaces need drainage before they are sealed.

Power company

Savannah Electric and Power merged into Georgia Power in July 2006, so most Savannah homes are Georgia Power customers and can look at its Home Energy Improvement Program for attic insulation and air sealing rebates. Get a free estimate

Savannah Questions

Can you insulate a house in the Savannah Historic District?

Yes. Attic, crawl space and under-floor work happens out of sight. Projects that change the exterior need to go through the city's historic review, so check with preservation staff if your plan involves the outside.

How much does spray foam cost in Savannah?

National guides put installed spray foam at about $1.50 to $5.00 per square foot. Older homes often need some removal and sealing first. We price it in writing after a visit.

Do I need closed cell in a Savannah flood zone?

Below the flood elevation, FEMA rates closed-cell foam acceptable and open-cell unacceptable, so we use closed cell there. We ask about your flood zone before quoting.

Do Savannah rentals benefit from insulation?

Yes. With almost 55% of occupied homes rented, many landlords seal and insulate attics to cut tenant complaints about hot rooms and high bills.
