Spray Foam Insulation in Noblesville, IN

Spray foam insulation in Noblesville means two very different kinds of jobs. Near the courthouse square, many houses date from the Indiana gas boom: Wikipedia notes that Noblesville's first natural gas well was found in 1888 near 11th and Pleasant streets, and that many Victorian homes and most of downtown were built in that period. Out at the edges of the city, the houses are much newer. The population went from 7,548 in 1970 to 28,590 in 2000 and 69,604 in 2020, and the 2020 census counted 27,101 housing units.

Victorian and early 1900s homes

The Catherine Street, Conner Street and South 9th Street historic districts, plus the downtown commercial district, are listed on the National Register. Houses of that age usually have balloon framing, where wall studs run from the foundation to the roof with nothing to stop air rising inside the walls. They often have plaster walls, steep roofs, attic rooms, and basements or crawl spaces of stone or brick. Foam is a good tool for blocking the tops and bottoms of those open cavities and for sealing rim areas that were never built to be tight. We check for knob-and-tube wiring and for moisture in old foundations before covering anything.

Keeping old houses able to dry

Old masonry foundations and solid-plank sheathing behave differently from modern assemblies. Closed-cell foam on a damp stone foundation wall can push moisture somewhere else. We look at drainage, the condition of the mortar and any signs of water before recommending foam below grade, and sometimes a different approach makes more sense.

Newer subdivisions

In the neighborhoods built since the 1990s, the usual list applies: rim joists, bonus rooms over garages, attic hatches, recessed lights and knee walls. Many of these homes sit over crawl spaces or basements on the same poorly drained till soils found across central Indiana. The USDA describes the common Crosby series as somewhat poorly drained with a perched water table 0.5 to 2 feet down in winter and spring, so crawl space moisture is worth checking even in a newer house.

Gas boom wiring and old materials

Homes built during and after the 1888 gas boom have seen generations of updates. It is common to find a mix of old wiring, newer circuits and abandoned gas lines in attics and walls. Knob-and-tube wiring should not be buried under insulation until an electrician has looked at it. We also watch for vermiculite in older attics and stop to recommend testing if we find it.

Mansard and steep roofs

The 1879 Hamilton County Courthouse and the 1876 Sheriff's Residence and Jail are both Second Empire buildings with mansard roofs, and some older homes in town share that style or have very steep roofs with small attics. Those roof shapes leave little room for loose fill. Foam from the inside of the roof framing or on the short attic floors is often the most practical way to insulate them.

Along the White River

The city sits along the White River at about 771 feet elevation. Homes in lower areas near the river and its creeks are more likely to have damp crawl spaces or basements. We check for water before quoting insulation work below the first floor. Get a free estimate
