Lexington's housing stock runs the full century: early 1900s bungalows in Chevy Chase and Ashland Park near the University of Kentucky, mid-century brick ranches scattered through the city, and newer subdivisions pushing toward Hamburg and Masterson Station, each with its own insulation headaches.

Older homes carry vented attics with thin, settled insulation and uninsulated rim joists that bleed heat all winter, while newer construction brings bonus rooms over garages and tall roof lines that bake in summer and never quite reach temperature. Between the Bluegrass humidity that drives moisture into walls in July and the cold snaps that reverse it in January, homeowners in Lexington (40505) call Lexington Spray Foam Insulation because we know exactly what fails in this climate and how to seal it right the first time.

Spray Foam Insulation in Lexington (40505)

This is IECC climate zone 4A, mixed-humid: hot humid summers push moisture inward through walls and ceilings, while cold winters and ice reverse that drive and pull moisture back out. Attics bake in summer, driving cooling bills through the roof, while poorly sealed rim joists and crawl spaces lose heat fast once the cold hits. Out through Jessamine, Scott, Bourbon, Lincoln, Henry and Mercer counties, the Bluegrass countryside holds horse farms, barns and farmhouses on limestone foundations with basements and crawl spaces that stay damp long after a storm passes. Older homes near downtown and the university are drafty and expensive to run because the rim joists were never sealed and the attic insulation has settled to nothing. Newer construction brings taller roof lines and bonus rooms that need an air barrier matched to that seasonal swing, or you end up with a room that never reaches temperature and a cooling bill you cannot explain.

We have been serving Lexington and the surrounding area since 2009. We understand the building stock here, the moisture challenges, and what spray foam and air sealing actually accomplish in this climate.

How a Job Works in Lexington

We start with a free on-site assessment. We walk the space with you, measure what we are looking at, identify what has to be sealed or removed, and explain what the code requires at your address. You get a written estimate that names the R-value, the thickness we will spray, the area to be covered, and the total cost. No surprises.

On the day of the work, our fully insured crew sets up mechanical ventilation to pull fumes and moisture out of the space during the cure. We spray to the thickness and R-value we quoted, controlling the ratio and drum temperature to the manufacturer spec. If we find wet insulation, a roof leak, or a crawl space with standing water, we stop and tell you what has to be fixed first. We do not spray over a compromised substrate, and we do not pretend foam fixes a leak. The space is off-limits for twenty-four to forty-eight hours while the foam cures and the ventilation runs.

Once cure is complete, we remove all equipment, tape and plastic, and walk the finished space with you. Your property is clean and ready to use.

Attic spray foam in Lexington typically runs from $1.50 per square foot for open cell foam to $1.20 per board foot for closed cell, depending on the R-value and thickness your attic needs and the condition of what is already there. A crawl space starts around $2,500, a rim joist and band joist job around $650, and a full insulation removal and replacement around $2,800. Wall injection foam for closed cavities runs from $2 per square foot. The cost factors are straightforward: how much area we are covering, what R-value and thickness the code requires at your address, whether you want open or closed cell (open cell is cheaper and breathes, closed cell is denser and stops air and moisture both), and whether we have to remove and haul away old insulation first. Metal buildings and barndominiums run from $1.75 per square foot. Call us at (859) 309-7396 for a free on-site estimate. We will give you a real number, not a range.

I have a bonus room over my garage in Hamburg that never gets warm in winter and never cools down in summer. What is going on?

A room over a garage is a classic problem in Lexington. The garage below is unheated, and the roof above is exposed to full sun in summer and full cold in winter. If the rim joist and band joist around the perimeter are not sealed, and the roof deck is not insulated, you are conditioning the garage and the sky instead of the room. Spray foam on the rim joist, closed cell foam on the roof deck under the shingles, and air sealing around the ductwork will fix it. Call us at (859) 309-7396 and we will walk the space with you.

My attic has condensation and damp insulation. Can we just spray foam over it?

No. If insulation is wet or damp, the substrate is not ready and the foam will trap moisture and make it worse. We have to find out why it is wet first. Usually it is a roof leak, a plumbing leak, or an attic that is not vented and is collecting humidity from the living spaces below. Once the leak is fixed or the ventilation is opened up, and the insulation has dried out, then we can spray. If the insulation is contaminated or the damage is too far gone, we remove it and haul it away, then spray new foam on a clean, dry substrate. This is not a shortcut we skip. Call (859) 309-7396 and we will tell you what we find.

What does spray foam actually cost for an attic in Lexington?

A typical attic in a mid-century ranch in Lexington might run 800 to 1200 square feet. At $1.50 per square foot for open cell foam, that is $1,200 to $1,800. If you need closed cell for better air sealing or higher R-value in a tight space, the cost goes up. If your attic already has insulation and we are just topping it up, blown-in fiberglass is sometimes the right answer and costs less. The only way to know is to have us look at it. Free estimate: (859) 309-7396.

Who decides what R-value and thickness I need in my attic, and how does the building department inspect it?

The energy code and building code in force at your address set the R-value minimum. In Lexington, that is governed by the local building official. We follow what the code requires and specify it in writing on your estimate. The ignition barrier and thermal barrier rules also come from the code, and they vary by attic ventilation, roof assembly and foam type. The building department may require an inspection after we finish. For the rules that apply at your specific address, contact the City of Lexington's building department through the official city website at https://www.lexingtonky.gov, or we can help you navigate what applies and what permits you need.

Can we live in the house while you spray foam in the attic?

Yes, but the attic itself is off-limits for twenty-four to forty-eight hours while the foam cures and mechanical ventilation runs to pull fumes and moisture out. We seal off the attic access and run ductwork to pull air from the space and exhaust it outside. The smell is strongest during the first few hours and fades as the foam sets. Once the re-entry window is done and ventilation is shut down, the space is safe to use. If you live in an attached townhome or a property with an HOA, let us know before we schedule, so we can coordinate with neighbors and follow any architectural rules for exterior ductwork.

Are you insured for this work?

Yes. We are fully insured with general liability and workers' compensation. Our crew is covered if anything goes wrong on your property, and you are protected. Before we start any job, we can show you proof of coverage.

When is the best time of year to spray foam an attic in Lexington?

Late spring and early fall are ideal. In summer, attics in Lexington bake to 130 degrees or more, which makes the foam cure too fast and can cause voids. In winter, cold temperatures slow the cure and make it hard to control. Spring and fall give us moderate temperatures and the time to do the job right. If you have a cooling bill that is out of control in July or you are losing heat in January, we can usually fit you in, but plan ahead if you can.
