An Old Resort Town's Housing
Spray Foam Insulation in Grand Ledge often means older homes. More than 26% of the city's housing dates from 1939 or earlier, a higher share than in Lansing itself. Settled in 1847, Grand Ledge became a resort town after Seven Islands Resort opened in 1872, near the sandstone ledges that rise 40 feet above the Grand River.
What older Grand Ledge homes need
Many pre-war houses here have balloon-framed walls, which let air run from the basement to the attic inside the wall cavities. Sealing the tops and bottoms of those cavities at the attic floor and the rim joist cuts a lot of air movement. Empty walls can then be dense-packed with cellulose. Attics often need sealing around chimneys and plumbing before more insulation goes on.
Newer homes
Outside the older core, homes from the 1970s on need smaller, targeted work: rim joists, attic top-ups and the occasional cold bonus room. The city's median home was built in 1974.
Near the river
Homes near the river and its islands may have damp basements, and older stone or block foundations can let moisture through. We check for water before recommending foam on basement walls.
Resort-era homes
At its peak in the late 1800s, Grand Ledge's resort drew an estimated 60,000 to 70,000 visitors a year, and the town grew with it. Homes from that period often have tall walls, steep roofs and finished upper rooms with kneewalls, which are hard to insulate with batts. Foam on sloped ceilings and kneewalls, or a sealed attic floor behind them, makes those rooms usable year-round.
Rental and investment houses
About a third of Grand Ledge's occupied homes are rented. For landlords, the quickest wins are the rim joist and attic, which cut tenant complaints about cold floors and drafts.
Steep roofs and ice dams
Older homes with steep roofs and finished upper floors often get ice dams where warm air leaks through kneewalls into the low attic spaces at the eaves. Sealing and insulating those kneewall attics, or foaming the roof deck in them, stops the melt that feeds the ice.
Owners
About two-thirds of Grand Ledge's occupied homes are owner-occupied. The city's 3,595 housing units had a 5.3% vacancy rate in 2020. Get a free estimate

Grand Ledge Questions
What is balloon framing and why does it matter?
Older houses were often framed with studs running from the foundation to the roof, leaving open channels inside the walls. Warm air rises through them into the attic. Sealing those channels at the top and bottom is one of the most useful things we do in old Grand Ledge homes.
Can you insulate plaster walls without tearing them out?
Yes. We drill small holes, blow in dense-pack cellulose, and patch. Spray foam is used only when walls are open.
Do you work on homes near the river?
Yes. We check basements for moisture first, since insulation should go on dry walls.
How much does it cost to insulate walls in an old house?
National guides put blown-in wall insulation at about $1.10 to $3.70 per square foot, or $1,900 to $7,800 for a typical house. We count your bays and quote in writing.
Do you also work outside the Grand Ledge city limits?
Yes. We work throughout the Grand Ledge area, including the surrounding townships.
