Crawl Space Insulation and Encapsulation
A poorly insulated or unencapsulated crawl space affects your entire home. Moisture enters from below, cold air rises through the floor, and your heating and cooling system works harder than it needs to all year long.York Home Performance provides crawl space insulation and encapsulation for homeowners across Pennsylvania and Maryland. We are a BPI-certified contractor with over 13 years of experience. We assess your crawl space before recommending any approach.
What an Uninsulated Crawl Space Does to Your Home
Most vented crawl spaces allow outside air and moisture to move freely beneath your living space. In winter that cold air rises through the floor. In summer, humid air enters and creates conditions for mold growth, wood rot, and structural damage over time.
Symptoms of a crawl space problem include:
- Cold floors in winter, especially on the first floor
- Musty odors coming from below the home
- Visible moisture or standing water in the crawl space
- Higher than expected energy bills
- Wood rot or pest activity beneath the home
- Humidity problems in the living space above
Crawl Space Services
Crawl Space Insulation
We install insulation between the floor joists above the crawl space or along the crawl space walls depending on whether the space is vented or conditioned. The right approach depends on your home's construction and goals.
Crawl Space Encapsulation
Encapsulation seals the crawl space with a heavy-duty vapor barrier on the floor and walls, closes vents, and converts the space from vented to conditioned. It eliminates the moisture and air quality problems associated with vented crawl spaces.
Vapor Barrier Installation
A vapor barrier alone is appropriate in some situations where full encapsulation is not needed. We assess whether a barrier is sufficient or whether full encapsulation is the right call for your specific crawl space.

We inspect the crawl space.
We assess moisture levels, current insulation, vapor barrier condition, and any signs of pest activity or structural damage.

Frequently Asked Questions About Crawl Space Insulation
What is the difference between crawl space insulation and encapsulation?
Insulation addresses heat transfer through the floor or crawl space walls. Encapsulation seals the entire crawl space with a vapor barrier and closes vents to control moisture and air quality. Many homes benefit from both, and the right combination depends on your specific crawl space conditions.
Do I need encapsulation or just insulation?
If your crawl space has moisture issues, encapsulation is typically the right solution because insulation alone will not address the moisture source. If the space is dry and the primary goal is thermal performance, insulation may be sufficient. We assess the conditions and give you an honest recommendation.
Will this improve my energy bills?
Yes. A properly insulated and encapsulated crawl space reduces cold air rising into your living space, which reduces the heating load on your home. Most homeowners notice a difference in floor temperatures within the first heating season after the work.
Can you work in a very low crawl space?
Yes. We work in crawl spaces of varying heights and conditions. We assess access and conditions during the estimate so there are no surprises on the job.
Where do you provide crawl space services?
We serve homeowners across Pennsylvania and Maryland including York County and surrounding PA counties, and the greater Baltimore and central Maryland area.
