Every winter, thousands of Long Island homeowners waste money heating the outdoors without realizing it. Gaps around hatches, thin attic insulation, and leaky ductwork silently drain energy and spike your utility bills.
An energy efficiency home inspection reveals those weak spots before the cold sets in. Our team identifies where your home is losing heat, and shows how simple upgrades can save you 15–25% on energy costs. It’s the best way to protect your comfort, your budget, and your home’s long-term value before the next big chill.

What’s Included in Our Energy Efficiency Home Inspection
An energy efficiency home inspection is a top-to-bottom evaluation of how well your home holds heat, moves air, and resists moisture. Our goal is to help you understand exactly where your energy dollars are going, and how to get the most comfort for your money.
Here’s what our certified team checks during every inspection:
- Attic & Crawl Space Insulation Assessment: We measure insulation depth and quality, checking for missing sections, gaps, and compression that let warm air escape.
- Air Leakage & Draft Detection: Using visual testing or thermal imaging, we identify leaks around windows, doors, top plates, and attic hatches, common culprits behind cold drafts and uneven heating.
- HVAC & Ductwork Inspection: We examine your heating and cooling system for efficiency losses, duct leaks, or disconnected runs that waste conditioned air.
- Moisture, Mold, & Ventilation Review: Poor ventilation can trap moisture and create mold risks. We perform mold testing with advanced equipment to assess airflow patterns and look for condensation or musty odors in attics, basements, or crawl spaces.
- Thermal Imaging: Infrared scans reveal invisible cold spots, insulation gaps, or thermal bridges that show where energy is leaking.
- Optional Blower Door Test: This test depressurizes your home slightly to measure total air leakage. While we may refer to this out, we’ll explain exactly how it works and what your results mean.
- Detailed Report & Upgrade Plan: You’ll receive a clear, photo-supported report outlining where energy loss is occurring and the best upgrades to improve comfort, efficiency, and long-term value.
Who Should Get an Energy Efficiency Inspection?
Almost every home can benefit from an energy efficiency inspection, but some homeowners see especially big gains both in comfort and cost savings.
You should schedule one if you:
- Have High Energy Bills: If your winter heating costs keep rising year after year, there’s likely hidden energy loss somewhere in your insulation or ductwork.
- Notice Cold Drafts or Uneven Heating: Rooms that never seem to warm up or sudden temperature changes between floors are signs of air leakage and poor insulation.
- Own an Older Home (Pre-1980s): Many Long Island homes built before modern energy codes lack proper insulation or sealing, especially in attics, crawl spaces, and rim joists.
- Plan to Upgrade Your Attic or Weatherproofing: An inspection helps you identify which upgrades will deliver the most impact before you spend a dime on improvements.
- Are a Landlord or Flipper: A documented inspection adds value to your listing and reassures buyers that the property is energy-efficient and comfortable.
Pro Tip: If your upstairs rooms are freezing in the winter, your attic may be leaking warm air like a chimney. A single inspection could uncover the fix that pays for itself in just one heating season.
Benefits of a Home Energy Efficiency Inspection
An energy efficiency inspection doesn’t just tell you where your home is losing energy; it helps you turn that knowledge into long-term savings and comfort. Whether you live in a pre-war Brooklyn brownstone or a postwar Long Island ranch, small improvements in insulation and sealing can make a huge difference.
Here’s what you gain from getting your home inspected:
- Lower Monthly Energy Bills: Stop wasting money heating and cooling the outdoors. Proper insulation and air sealing can cut heating costs by up to 15–25%, and improve summer cooling efficiency too.
- Better Comfort and Indoor Air Quality: Eliminate cold drafts, reduce temperature swings, and improve air circulation for a more consistent, breathable home environment.
- Longer HVAC Lifespan: When your home retains heat efficiently, your system doesn’t have to run as often, reducing wear and tear and extending equipment life.
- Moisture and Mold Prevention: By sealing gaps and improving ventilation, you reduce humidity buildup that causes attic mold, condensation, and wall damage.
- Rebate and Upgrade Readiness: Your inspection report provides documentation that can help qualify for energy-efficiency rebates or tax credits.
- Higher Resale Value: A documented energy inspection boosts buyer confidence and makes your home stand out in a competitive market.

Case Study: Crawl Space Encapsulation & Mold Prevention in Carle Place, NY
A homeowner in Carle Place, NY contacted Zavza Seal after noticing persistent musty odors and humidity inside their home. The source? A damp, debris-filled crawl space that was affecting indoor air quality and creating the perfect environment for mold growth.
The Problem
The 400-square-foot crawl space beneath the home was unsealed, dirty, and constantly damp. Without a vapor barrier or proper insulation, it allowed moisture and cold air to rise into the living areas above. This led to poor air quality, high energy bills, and the risk of mold, mildew, and pest infestations. The homeowner needed a lasting solution to protect their home’s structure and indoor environment.
The Solution
Zavza Seal designed a complete crawl space encapsulation and air-quality improvement plan to turn the damp space into a clean, sealed, and healthy environment.
Here’s what we did:
- Debris Removal & Deep Cleaning: Cleared all dirt, debris, and contaminants to prepare for sealing.
Disinfection & Rodent Repellent: Applied an all-natural, EPA-registered disinfectant that kills mold spores and prevents pest nesting. - High-Performance Vapor Barrier: Installed a reinforced 15-mil crawl space membrane across floors and walls for full moisture protection.
- Anchoring & Air Sealing: Secured the barrier to foundation walls and sealed rim joists with spray foam to eliminate air leaks.
- Dehumidification System: Installed dehumidifiers with condensate pumps to maintain optimal humidity levels.
- Insulation Upgrade: Added new R-19 vapor-faced insulation for energy efficiency and consistent indoor temperatures.
The Outcome
The crawl space was transformed from a damp, musty area into a clean, dry, and fully encapsulated zone. The homeowner now enjoys:
- Fresher indoor air quality
- Lower humidity and reduced mold risk
- Greater energy efficiency and comfort year-round
Zavza Seal is trusted across Long Island for professional crawl space encapsulation, mold prevention, and insulation upgrades.

Frequently Asked Questions About Home Energy Efficiency Inspections
Do I need to leave the house during the inspection?
No, not at all. Most inspections are non-invasive and take place while you’re home. Our technicians may need brief access to your attic, crawl space, or mechanical room, but there’s no disruption to your day.
Is this the same as a NYSERDA energy audit?
Not exactly. A NYSERDA audit is a state-subsidized program with strict qualification rules and paperwork. Our energy efficiency inspection delivers faster, practical results, and we can still help coordinate with NYSERDA or PSEG if you qualify for rebates.
Do I have to upgrade everything you recommend?
No. You’re in full control. Our report gives you clear options ranked by impact and budget so you can start with the improvements that make the most sense for your home.
How soon will I see savings?
Many homeowners notice lower heating bills and more consistent comfort in the very first month after sealing leaks or adding insulation. Full ROI typically happens within one or two seasons, depending on upgrade size.
Can renters request an energy efficiency inspection?
Yes. Renters can schedule an inspection with landlord permission. Many property owners appreciate the insights, especially when planning upgrades for tenant comfort or resale value.
