Crystal is a lake community in northern Montcalm County, with year-round homes and seasonal cottages around Crystal Lake. Many of those homes have basements or crawlspaces with uninsulated rim joists and sill plates, where cold air pours in all winter. Energy Plus Home Improvements has served Mid-Michigan since 1971 from Riverdale, about 11 miles northeast of Crystal. We seal and insulate rim joists with spray foam, encapsulate crawlspaces and bring attics up to recommended levels. Every installation is backed by the EP Protection Plan™.

Quality You Can Trust
The rim joist is the band of framing where the floor sits on the foundation. In most homes it has little or no insulation and plenty of gaps, so cold air flows straight into the basement. Closed-cell spray foam seals and insulates it in one step, as on the Mt. Hope Road project.
Homes near the water see more ground moisture. A sealed crawlspace liner and foamed walls keep damp air from rising into the house, which also helps cottages that sit closed in winter.
We also install EP FoamCore™ spray foam, EP CrawlGuard™ crawlspace encapsulation and EP RetroCore™ wall insulation. Final pricing is confirmed after we inspect the home.
Crystal is unincorporated, so requirements come from Crystal Township or Montcalm County and depend on the scope. We confirm the requirement for your address and pull the permit when one is needed.
Local Expertise
Crystal is an unincorporated community in Crystal Township, in northern Montcalm County, where Crystal Lake, Mud Lake and Duck Lake sit. The lake is the center of local life, with boating, fishing and the annual Duck Days, and the township has grown from 222 residents in 1860 to about 2,600 today.
Homes range from year-round houses to seasonal cottages. Each estimate states what we found, what we recommend, and anything we cannot confirm until we are in the basement, crawlspace or attic.

Answers to the questions we hear most often about insulation projects.
The rim joist is the framing band on top of the foundation. Spray foaming it seals air leaks and adds insulation in one of the coldest parts of a basement or crawlspace.
Closed-cell foam resists moisture and acts as a vapor retarder, which makes it a good choice for basements and crawlspaces near the water.
Yes, if it is used in fall or winter or sits closed with moisture problems. Sealing the crawlspace and attic floor keeps it drier and warmer.
Most homes take a day or less, depending on the length of the rim joist and access. The foam cures quickly.
Crystal is unincorporated, so requirements come from Crystal Township or Montcalm County. We confirm the requirement and pull the permit when one is needed.
