AIR SEALING SERVICES

Professional Air Sealing Services

Improve Energy Efficiency & Indoor Comfort
Even the best insulation system can lose effectiveness if air leaks are present throughout the property. Small gaps, cracks, and openings can allow conditioned air to escape while letting outside air, moisture, and contaminants enter your home or building.
At CRG Insulation & Acoustical Inc., we provide professional air sealing services throughout the Bay Area and Northern California to help improve insulation performance, energy efficiency, and indoor comfort.
WHAT IS AIR SEALING?

What Is Air Sealing?

Air sealing is the process of identifying and sealing areas where air escapes or enters a home or building. These air leaks commonly occur around structural gaps and openings throughout the property.
Sealing these openings helps improve the overall performance of your insulation system and HVAC equipment.

BENEFITS OF PROFESSIONAL AIR SEALING

Improve Comfort, Efficiency & Indoor Air Quality

Air sealing provides several long-term benefits for residential and commercial properties throughout the Bay Area and Northern California.

01

Improved Energy Efficiency

Sealing air leaks reduces the amount of conditioned air that escapes, lowering overall energy demands throughout the year.

02

Reduced Heating & Cooling Costs

Less air loss means your HVAC system works less to maintain indoor temperatures, which can lower utility bills.

03

Better Indoor Temperature Control

Sealing drafts and gaps helps maintain consistent temperatures throughout every room of the property.

04

Reduced Drafts

Eliminating air leaks removes uncomfortable drafts that make rooms feel cold in winter or warm in summer.

05

Improved HVAC Performance

A well-sealed property allows heating and cooling equipment to operate more efficiently and with less strain.

06

Better Indoor Air Quality

Sealing openings reduces the entry of outdoor dust, pollutants, allergens, and contaminants into the property.

07

Reduced Moisture Intrusion

Proper air sealing helps prevent moisture from entering through gaps and causing damage to insulation and building materials.

08

Improved Insulation Performance

Air sealing and insulation work together — sealing gaps ensures insulation achieves its full rated thermal performance.

09

Enhanced Overall Comfort

A properly sealed property delivers more consistent, comfortable indoor conditions throughout every season.
