Insulation contractor in Collierville, TN - attics sealed, then insulated
Barrier Memphis Insulation Company is an insulation contractor in Collierville, TN. We seal air leaks in attics, crawl spaces and walls, then add or replace insulation so hot upstairs rooms and cold floors stop fighting your heating and cooling.
Old Main Street houses and newer subdivisions
As an insulation contractor based in Memphis, TN, we work across Shelby County, and Collierville is one of the cities we know well, right next to Germantown. The houses here usually fall into two groups. The older ones sit around the Town Square and the historic district along Main Street. Most of the rest of the city is newer subdivision housing, with big attics, a bonus room over the garage and the heat and air often running through the attic.
That split decides the job. In an older house we start with what's already up there and whether it can stay. In a newer one we start with the ducts and the room over the garage.
Working in Collierville: permits, licenses and price
The Town of Collierville does its own plans review, which is the check of building plans before work starts, and its own code enforcement. That means permits here go through the city's Building & Codes Division, not the state's residential permit program. Whether your job needs a permit is the city's call. When it does, the work waits until the permit is issued, so the permit can push the start date. Building & Codes answers questions about an application at (901) 457-2310. When a job calls for a permit, we handle the application and set up the inspections. Before you hire anyone, ask to see their business licenses, because Shelby County requires every business to register with the County Clerk for one, and a business working inside a city needs that city's license too. We're licensed and insured.
Here, the price depends on what's already in the attic, whether old material has to come out first, how many gaps need sealing and whether ductwork runs through the attic. The schedule depends on that same cleanup and on the permit, if there is one. Your estimate gives you the figure for your house. We do the same work down in Hernando, and the order of the steps stays the same from one city to the next.

Older attics and bonus rooms both need sealing first
In the older houses near the square, we usually find a few inches of tired insulation, sometimes stained or full of droppings, and open gaps around the chimney, the attic hatch and the can lights. Piling new material on top hides the problem. So we pull out whatever is soaked or dirty and seal the gaps so air stops leaking through. Then we add fresh loose fill, full depth out to the edges and clear of the eave vents so the attic can still breathe.
Newer houses here often keep the furnace and ducts in the attic and the water heater in the garage, and the bonus room over the garage often runs hot. I spent years in heating and cooling before I started this business in 2021. So before we tighten up any house, I check that everything burning gas still gets the fresh air it needs, because a tighter house only helps if it's safe to live in. Where a house has a basement, basement insulation follows the same order.

Insulation questions from Collierville homeowners
How much does insulation cost for a house in Collierville, TN?
It comes down to your house, so I'd rather see the attic than guess. The biggest choice is foam or loose fill. Foam costs more and seals air as it insulates. Sealing the gaps and topping up with blown-in, which is loose fill blown through a hose, usually wins unless your ductwork runs through the attic. Old material that has to come out first adds to the cost too.
What building code does Collierville enforce right now?
The city currently enforces the 2018 code edition, according to a city staff report. A proposed ordinance would move Collierville to the 2024 International Code Council codes, including the residential code, and to the 2021 energy code. It stays a proposal until the city adopts it. When your job needs a permit, we check which edition the city is applying at that point.
Who can do electrical, plumbing or HVAC work on my Collierville house?
The city's permit portal says all mechanical work, which covers heating and cooling, plus all plumbing and electrical work needs a State or Shelby County licensed contractor. Insulation jobs sometimes turn up problems in those trades, like a loose bath fan duct or old wiring buried in the attic. When I find one, I point it out before we insulate, and that part goes to a contractor licensed for it.
How do I check my permit status or inspection results in Collierville?
Use the city's Online Permit and Application Center, which shows the public permit status, permit reports and inspection results. You can also request an inspection there or confirm one is scheduled. On jobs where we pull the permit, we set up the inspections, but you can look up where things stand anytime.
How long do we have to stay out of the house after spray foam insulation?
The foam maker sets the re-entry time, which is how long you wait before you can come back inside, and it changes from one product to the next. I tell you the wait for your job before we start, so you can plan for the kids and pets. Loose fill and most sealing work don't usually call for that kind of wait, and I'll tell you if yours does.
What causes the room over my garage to run hot?
Usually it's air leaking in from the garage and the attic, plus thin insulation in the knee walls, the short walls along the sloped ceiling, and in the floor over the garage. Insulation alone won't fix it while air still moves through those gaps, so we seal first and then insulate. If that room's duct runs through the attic, it's often part of the problem too.
