Spray Foam Insulation on Lookout Mountain, Tennessee

Spray foam for Lookout Mountain homes

Lookout Mountain, Tennessee is a town of about 2,100 people on top of the mountain that overlooks Chattanooga from the south. It covers just over a square mile and borders its sister city, Lookout Mountain, Georgia. The mountain is home to some of the area’s best-known landmarks and to Point Park, part of the Chickamauga and Chattanooga National Military Park.

Historic homes on the mountain

Many homes on Lookout Mountain are older, some dating to the early 1900s, built of stone, brick and wood on wooded lots. Many have crawl spaces or basements with stone or block foundations, attics that were never well insulated, and a lot of character that owners want to keep.

Mountain conditions

Like Signal Mountain across the valley, Lookout Mountain gets more wind and colder winters than the city below. Fog and cloud often sit on the mountain, keeping things damp. Older homes with gaps around windows, doors, foundations and attic floors lose a lot of heat to wind-driven drafts.

Where foam helps

• **Stone and block foundations.** Closed-cell foam on the rim joist and on dry foundation walls seals the largest air leaks in many older homes.
• **Attic floors.** Foam air sealing at top plates, chimneys, plumbing chases and wiring holes, followed by blown insulation, is often the best fit for historic attics.
• **Cathedral and vaulted ceilings.** Where there is little space for insulation, closed-cell foam gives the most R-value per inch.
• **Additions and sunrooms.** Rooms added over the years are often the coldest in winter and the hottest in summer.

Careful work in older homes

We do not foam over active leaks or damp stone. We check for knob-and-tube wiring, which should be looked at by an electrician before it is covered. We look at fireplaces, chimneys and gas appliances, which need proper clearances and combustion air. If a historic home has features you want to protect, tell us and we will plan around them.

Request a quote

Send your address or ZIP, the age of the home, and what you want to fix. Photos of the attic, basement or crawl help. See our attic air sealing guide. Signal Mountain homes face similar conditions.

Roof replacement timing

If you are planning a new roof, foam on the roof deck is best done after the new roof is on, so any wood damage is fixed first and the foam goes on clean, dry sheathing.

We also serve homeowners on the Georgia side of the mountain. Georgia’s code requirements differ slightly from Tennessee’s, and we confirm what the local inspector expects before work starts.

Wooded lots also mean squirrels and other animals in attics; we check for signs of them before insulating.
