Finishing What the Builder Started

Spray foam insulation in Ankeny usually starts in the basement. The city has grown quickly: Wikipedia counts 27,117 residents in 2000, 45,582 in 2010 and 67,887 in 2020. Point2Homes data puts the median year built at 2006, with 21.9% of homes built from 2000 to 2009, 32.8% in the 2010s and 8.1% since 2020. Many of those houses were sold with unfinished basements, and owners are now finishing them.

The basement project

If you are finishing an Ankeny basement, the best time to insulate is before the framing goes up. We spray closed-cell foam on the rim joist and the foundation walls. Iowa's code table lists R-15 continuous or R-19 cavity for basement walls in Zone 5, and about three inches of closed-cell reaches the low end of that while keeping humid summer air away from the concrete. Your framer can follow right behind.

Rooms over garages

Two-story homes with attached garages are common in Ankeny's newer neighborhoods. The bedroom or bonus room over the garage is often the coldest room in the house. We seal and insulate the garage ceiling and the rim where it meets the house.

Snow and cold

Wikipedia's Ankeny climate data lists about 24.7 inches of snow a year and a record low of -34F. Even a newer house can build ice dams if warm air leaks into the attic at light fixtures and the hatch, so we seal those before topping up.

A city of owners

About 71.4% of Ankeny's 28,361 occupied homes are owner-occupied. The city's history runs from its founding in 1875 to the John Deere Des Moines Works, which opened in 1947 in a former World War II ordnance plant, and Prairie Trail, built from 2005 on a former Iowa State University research plot.

A typical Ankeny job

A 2012 two-story with an unfinished basement and a bonus room over the garage is a common call. We foam the rim joist and the foundation walls, spray closed-cell on the garage ceiling below the bonus room, and check the attic for gaps around recessed lights and the hatch. Total time is usually a day or two, and the basement is ready for framing once the foam cures.

What to budget

Nationally, HomeGuide puts closed-cell foam at $3.00 to $5.00 per square foot installed and rim joists at about $2,000 to $2,500. Basement walls add square footage quickly, so we measure each wall and list it separately. Our written estimate is the final price. Get a free estimate

Ankeny Questions

My Ankeny house is only ten years old. Does it need more insulation?

Usually the attic is close to target, but rim joists and garage ceilings are often weak spots. We check and only quote what helps.

Can you foam my basement before my contractor frames it?

Yes. We schedule so the foam is cured and ready when the framer arrives.

Is spray foam required to pass inspection on a basement finish?

Not necessarily; other insulation can work. Ask the city about permits for your project. Foam is often the simplest way to meet the wall target in a small depth.

How long before I can frame after foam?

Once the foam has cured, usually the next day. We tell you when it is ready.
