Crawl Space Insulation for Charlotte Homes
A damp, drafty crawl space makes the whole house more challenging to heat and cool. Insulating it helps block moisture, cut energy bills, and keep floors more comfortable year-round. We’ve been fixing crawl space problems in Charlotte homes for over 80 years, and we know how to get it right the first time.
Signs Your Crawl Space Needs Insulation
If your crawl space is uninsulated or full of old, sagging material, it can affect comfort, energy use, and even air quality inside your home. Here are some common signs it’s time for an upgrade:
- Drafts or cold air near floor level
- Insulation is falling or completely missing
- HVAC struggles to heat or cool your home
- Condensation or moisture collects below the floor
Drafts or cold air near floor level
What to look for: Cold floors in winter often come from below. An uninsulated or under-insulated crawl space lets cold air press against the floorboards, making your heating system work overtime.
What to check: On a chilly morning, walk barefoot across your first floor. If certain areas feel noticeably colder, especially near exterior walls, check the insulation beneath.
Insulation is falling or completely missing
What to look for: If fiberglass batts are hanging down or have disappeared entirely, they’re no longer insulating your floor. This opens the door to drafts, higher energy use, and pest problems.
What to check: Shine a flashlight under your crawl space. Insulation should be snugly secured between each floor joist. Sagging or bare cavities are signs it needs replacement.
HVAC struggles to heat or cool your home
What to look for: When your system seems to run constantly yet can’t maintain a set temperature, the crawl space might be working against you. Poor insulation there affects the entire house.
What to check: During an HVAC service, ask the tech about system load and heat loss. If your floors are cold or inconsistent, the issue might be below, not above.
Condensation or moisture collects below the floor
What to look for: When warm indoor air meets a cold crawl space floor, moisture forms. Over time, that leads to mold, warped wood, and ruined insulation.
What to check: Look underneath the floor for water stains, soggy insulation, or puddles. Moisture meters can give a more precise reading, but visible dampness means action is needed.
The Benefits of Crawl Space Insulation
Adding insulation to your crawl space pays off fast in both comfort and efficiency.
Crawl Space Insulation Project Before & After
Warmer floors in winter
Insulation helps block cold air from reaching your subfloor, which makes first-floor rooms feel more comfortable—even on cold mornings.
Lower heating and cooling costs
Insulated crawl spaces reduce how much outside air sneaks into your home. That means your HVAC system doesn’t have to run as long or work as hard.
More consistent indoor temperatures
When insulation is properly installed and supported, it helps eliminate cold spots, drafts, and heat loss through the floor.
Fewer issues with pests and moisture
Sealing key gaps and adding insulation helps deter pests and reduces the amount of humid air reaching your subfloor and flooring system.
Our Crawl Space Insulation Installation Process
Installing crawl space insulation isn’t just about filling the joists. We look at how the space is built, how it’s vented, and what it takes to stop moisture and heat loss at the same time. Here’s what to expect:
Free Energy Analysis
We assess your crawl space for heat loss, air leaks, dampness, and missing insulation.
Remediation
We clean out debris, remove damaged materials, and dry the space if needed.
Installation
We install fiberglass batts between joists or rigid foam on the walls depending on design.
Air Sealing
We seal rim joists, sill plates, and any other gaps pulling in outside air.
Securing Insulation
We fasten batt insulation with supports so it stays snug against the subfloor.
Quality Check
We confirm everything’s sealed and covered properly, clean up, and walk you through it.

Frequently Asked Crawl Space Insulation Questions
What’s the difference between insulating crawl space walls vs. floors?
Insulating the crawl space walls treats the entire area as part of the thermal envelope and is often more effective for air sealing. Floor insulation only helps if the crawl space is vented. The DOE recommends insulating walls for conditioned crawl spaces.
Is fiberglass or foam board better for crawl space insulation?
Foam board is often preferred in crawl spaces because it resists moisture and provides higher R-value per inch. Fiberglass can sag or absorb water over time if not properly encapsulated or sealed.
Should a vented crawl space be insulated in Charlotte?
Yes. Even in vented crawl spaces, floor insulation and vapor barriers help reduce heat loss and moisture. However, sealing and conditioning the space is generally more efficient and preferred for Charlotte’s climate.
How do I know if my crawl space insulation needs to be replaced?
Common signs include visible sagging, wet or moldy insulation, cold floors above the space, and pest infestations. An inspection from a qualified insulation contractor can confirm the best solution.
