Nothing. Nashville's Best Pros is free for homeowners and free for home service businesses. We do not charge for introductions, we do not take a commission on the work, and we do not sell your details on.

Each business states its own credentials, and profiles that claim to be licensed or insured show that as a badge. Those claims come from the business rather than from us, so ask to see the paperwork before work starts — any legitimate insulation contractor will expect the question.

Each business sets its own service area. This page shows insulation businesses covering Lebanon and Wilson County, including Nashville, Franklin, Brentwood, Murfreesboro, Hendersonville and more.

Most often: upstairs rooms never cool down; energy bills climbing every year; ice or condensation in the attic; draughts you cannot trace. You do not need to know the name of the fix to ask — describe the symptom in your enquiry and the insulation contractor will tell you what it is.

Usually attic insulation and air sealing rather than the air conditioner. Heat radiates down from an attic that reaches well over 130°F in a Middle Tennessee summer, and air leaks at can lights, top plates and the attic hatch let conditioned air escape upward. Undersized or leaking ducts in the attic compound it. Adding insulation without sealing the leaks first gives a fraction of the benefit.

Around R-38 to R-49 for this climate zone, which is roughly fourteen to twenty inches of blown fibreglass or cellulose depending on the material. Many houses here built before the 2000s have half that. If you can see the tops of the ceiling joists when you look across the attic, there is not enough.

Batts are fibreglass rolls fitted between framing — cheapest, and only as good as the fit. Blown-in fills irregular spaces and is the usual choice for topping up an attic. Spray foam both insulates and air seals in one step and has the highest R-value per inch, which is why it is used at rim joists and in unvented attic assemblies. It also costs the most by a wide margin.

Attic insulation and air sealing return more per dollar than almost any other efficiency work, including windows — which is why an honest energy assessment starts there. The payback is usually a few years rather than decades. The comfort difference in upstairs rooms is often more noticeable than the bill difference, and it is the reason most people actually do it.

Warm moist air from the house is reaching a cold attic and condensing — from bathroom fans venting into the attic instead of outside, gaps around the attic hatch and light fittings, or inadequate ventilation. It is a moisture and air-sealing problem rather than an insulation one, and adding insulation on top without fixing it traps the moisture and rots the sheathing.
