Crawl Space Insulation
Crawl Space Insulation Solutions in Rochester, Ithaca, Syracuse & the Finger Lakes
Keep Your Home Comfortable, Healthy & Energy Efficient with Professional Crawl Space Insulation
A poorly insulated crawl space is one of the biggest hidden sources of energy loss and discomfort in a home. At AB Insulation, we specialize in transforming cold, damp, inefficient crawl spaces into clean, insulated, energy saving parts of your home’s building envelope.
Whether your floors are freezing in winter, your energy bills keep climbing, or your crawl space smells musty, our team delivers long lasting solutions that improve comfort, protect your home, and reduce energy costs.
Why Crawl Spaces Cause Major Comfort & Energy Problems
Crawl spaces sit directly on the cold, damp earth. Without proper insulation and moisture control, they:
-
Pull cold air into your home
-
Make floors above the crawl space icy in winter
-
Force heating systems to work harder
-
Create ideal conditions for mold, pests, and wood rot
-
Increase energy bills year-round
If your water heater, furnace, ductwork, or plumbing runs through the crawl space, the temperature swings can dramatically reduce efficiency and shorten equipment lifespan.
AB Insulation installs durable, high performance crawl space insulation systems designed specifically for these harsh conditions.
Signs Your Crawl Space Needs Better Insulation ​
Floors above the crawl space are cold in winter
Rooms above the crawl space are hard to heat
Fiberglass insulation is sagging, damp, or falling down
Musty odors or visible mold in the crawl space
Rodents or pests present
High energy bills with no clear cause

Most Homes Have the WRONG Crawl Space Insulation
Traditional fiberglass batts installed between floor joists are not designed for crawl spaces.
-
Absorb moisture
-
Grow mold
-
Sag and fall out
-
Lose R-value quickly
-
Attract pests
This outdated method leaves your crawl space cold, damp, and inefficient.
AB Insulation uses modern, high-performance materials engineered specifically for crawl space environments.
Rigid Foam Insulation (Crawl Space Walls)
Rigid foam is the gold standard for crawl space wall insulation.
Benefits include:
-
Energy Efficiency: Reduces heat loss and prevents air leaks
-
Durability: Won’t sag, compress, or deteriorate
-
Moisture Resistance: Won’t absorb water or support mold growth
-
Improved Comfort: Warmer floors in winter, cooler floors in summer
-
Tax Credit Eligible: Qualifies for federal insulation tax credits
By insulating the crawl space walls instead of the floor, we bring the crawl space inside the home’s thermal envelope, dramatically improving comfort and efficiency.

Frequently Asked Questions & Answers
​
Why are my floors cold above the crawl space in winter?
Cold floors are one of the most common signs of a failing or inadequate crawl space insulation system. Most older homes use fiberglass batts between floor joists, which absorb moisture, sag, and lose their effectiveness over time. AB Insulation installs rigid foam on crawl space walls, which is far more effective at blocking cold air and improving floor comfort. Call (315) 597-7000 to schedule a free assessment.
What is the best insulation for a crawl space?
Rigid foam board insulation installed on the crawl space walls is the most effective and durable solution available. Unlike fiberglass batts, rigid foam won't absorb moisture, won't sag, resists mold, and maintains its R-value for the life of the home. This approach brings the crawl space inside the home's thermal envelope, improving efficiency throughout the entire house. AB Insulation installs rigid foam crawl space systems across Central and Western New York.
Can New York homeowners get rebates for insulation upgrades?
Yes — New York homeowners may qualify for NYSERDA rebates and federal tax credits of up to $1,200 on qualifying insulation improvements. Programs like NYSERDA EmPower+ and the Comfort Home program can significantly offset the cost of upgrading your crawl space, attic, or wall insulation. AB Insulation helps customers identify and apply for every available incentive. Call (315) 597-7000 to find out what you qualify for.
What are the signs my crawl space insulation needs to be replaced?
The most common warning signs include cold floors, musty odors, visible mold, sagging or damp fiberglass batts, pest activity, and unexplained spikes in your energy bills. If your crawl space insulation is more than 15 years old, it may no longer be performing effectively. AB Insulation offers free crawl space assessments for homeowners throughout the Rochester, Syracuse, and Finger Lakes areas. Call (315) 597-7000 to schedule yours today.
How much can I save on energy bills with crawl space insulation?
A properly insulated and air-sealed crawl space can reduce your heating and cooling costs by 15–25% depending on your home's current condition. By eliminating cold air infiltration from below, your heating system runs less and works more efficiently. NYSERDA data shows that homes completing full seal and insulate packages average around 20% in annual energy savings. AB Insulation serves homeowners throughout Central and Western New York — call (315) 597-7000 for a free estimate.
Does crawl space insulation help with moisture and mold problems?
Yes — moisture control is one of the biggest benefits of a properly insulated crawl space. Rigid foam insulation combined with vapor barriers and air sealing dramatically reduces ground moisture and humid air intrusion, which are the primary causes of mold and wood rot in crawl spaces. Unlike fiberglass, rigid foam does not absorb water or support mold growth. AB Insulation provides complete crawl space moisture and insulation solutions throughout the Finger Lakes and surrounding regions.
Will insulating my crawl space protect my pipes and HVAC equipment?
Absolutely. Homes with uninsulated crawl spaces expose their ductwork, water pipes, and mechanical equipment to extreme cold, reducing efficiency and increasing the risk of frozen or burst pipes during New York winters. By insulating the crawl space walls and sealing air leaks, AB Insulation brings the entire space inside the home's thermal envelope — protecting your systems and extending their lifespan. Call (315) 597-7000 to learn more.
