Wall insulation in Clarksville TN - warmer rooms without tearing out your walls

Most wall calls we get are about one room, usually the one with three outside walls that stays cold no matter where the thermostat sits, or an older house where nobody ever put anything in the walls. The price moves with how many walls we're filling, what's on the outside of them, whether they're open or closed, and whether we find water damage that has to be fixed first. The schedule turns mostly on that repair and on whether you've got a siding or remodel job coming that we can line up with. If the draft is really coming from gaps around windows, outlets and the attic floor, air sealing services may do more for that room than insulation alone, and when I come out to look, you get a figure for your own walls and my honest read on which one you need.

I start every wall job by looking for water, because insulation packed into a wet wall doesn't fix anything, it just hides the problem until the paint starts bubbling. We check the siding, the sheathing behind it where we can get a look, the window framing and the inside walls for stains, soft spots and rot, and any repair comes before the insulation does. Once the walls are sound, we talk through whether to go in through small holes or wait until your siding or drywall is off anyway, then we fill each bay full, work around the pipes and wires in there, and patch and clean up behind us.

Walls are only one side of the house. Gaps around outlets, trim and the top of the wall let air slip right past new insulation, so we often pair a wall job with air sealing, and if the cold is coming up from below, basement insulation handles the foundation walls the framing upstairs never touches.

The City of Clarksville issues residential building permits for construction, additions and renovations, and Montgomery County's permit list covers single family homes, additions, renovations and fire restoration, but neither one names wall insulation, so I won't tell you from here whether your job needs a permit. Before we start, we find out whether your address falls under the city or the county and what that office wants, and when our part of the job needs a permit, we take care of it. If you're acting as your own contractor on a city permit for a bigger remodel, the city asks for a notarized Homeowner Affidavit that puts the permit and the construction on you. The city also points out that under state law, any project with a total value of $25,000 or more has to be done by a contractor licensed by the State of Tennessee, which is worth knowing if wall insulation is riding along with a large remodel.

A lot of the older houses we get into around here have nothing in the walls but air and the occasional wasp nest, and some have new siding over old siding, so we figure out how many layers we'd be going through before we pick a side to work from. We're based in Clarksville and work across the cities around it on both sides of the state line, and we run into the same mix of houses on jobs in Pleasant View and Oak Grove.
