An Old Mill Town East of Gaylord
Spray Foam Insulation in Johannesburg covers a rural community east of Gaylord that began with lumber. A branch of the Michigan Central Railroad reached the site from Sallings in 1887, and the Johannesburg Manufacturing Company, a lumbering and milling firm, built the community around its operations. The town took its name from Johanna Hanson, wife of the company's president, and its post office opened in 1901.
High and cold
Johannesburg sits at about 1,352 feet, on the high ground of Otsego County. Otsego County is in Climate Zone 6A on OpenEI's list, and winters here are as long and snowy as Gaylord's. Attic sealing and depth, plus rim joist foam, are the core of almost every job.
Rural homes and buildings
Most properties around Johannesburg are rural: homes on acreage with garages, pole barns and sheds. Steel buildings drip in fall and spring; closed-cell foam on the steel stops it and holds heat in a shop.
Cabins and hunting camps
The forests around Johannesburg hold cabins and hunting camps built for occasional use. If a camp will be used in winter, sealing the floor or crawl space and insulating the ceiling are the first steps.
Planning around travel
Rural jobs get the same inspection and itemized quote as in-town work. Travel is included in the estimate.
Fieldstone and block foundations
Older rural homes often sit on fieldstone or block foundations with irregular surfaces. Closed-cell foam bonds to uneven stone and block better than rigid board, sealing the cracks where cold air gets in.
