Spray Foam Insulation in DE, NJ, and PA
DOE-Certified Installation & Verification

When you need spray foam insulation in DE, NJ, and PA, you're not just looking for someone who can apply foam—you need a contractor who can prove the work meets federal energy efficiency standards. Energy Services Group doesn't just install spray foam insulation. As a DOE-Certified Verifier and official DOE Partner (ID 2782/866), we verify that every installation meets the standards required for Energy Star and federal energy programs.

We've certified over 2,700 homes across Delaware and the tri-state area. We understand what Delaware homeowners face: coastal moisture issues, older housing stock with air leakage, and utility bills that climb every season.

The ESG Difference:
Installation Backed by Federal Verification

Most insulation contractors install spray foam and move on. We take it further.

As a DOE-Certified Verifier, we don't just apply foam—we conduct post-installation verification to confirm your insulation meets federal energy efficiency standards. This matters if you're pursuing Energy Star certification, participating in utility rebate programs through Delmarva Power or PECO, or building to DOE "Efficient New Home" standards.

Our verification includes thermal imaging to identify missed areas, R-value testing to confirm performance, and documentation that proves compliance. This isn't an upsell—it's standard practice for us because we're held to a higher standard as a DOE Partner.

We've completed over 2,700 certified homes since 2015, and we maintain an A+ BBB rating. We're not high-pressure salespeople. We're technical specialists who understand building science and energy performance.

What to Expect: Our Installation Process

1. Home Energy Audit & Assessment

We start with a comprehensive energy audit to identify air leakage, insulation gaps, and moisture concerns. This determines where spray foam will deliver the greatest impact.

2. Preparation & Protection

We protect your belongings, seal off work areas, and ensure proper ventilation. You'll know exactly what to expect before we begin.

3. Professional Application

Our installers apply spray foam using professional-grade equipment, ensuring proper coverage, thickness, and expansion. We follow manufacturer specifications and building codes.

4. Post-Installation Verification

We conduct thermal imaging and performance testing to verify the installation meets DOE standards. You receive documentation of compliance.

Common Concerns About Spray Foam Insulation

Spray foam costs more initially than fiberglass or cellulose, but it delivers superior air sealing and long-term performance. For Delaware homeowners with high utility bills or comfort issues, the investment typically pays back through reduced heating and cooling costs. We provide realistic timelines—not inflated savings promises.

Spray foam has an odor during application and curing (typically 24 hours). We coordinate timing to minimize disruption and ensure proper ventilation. Once cured, it's inert.

This is exactly why our DOE verification matters. You get third-party confirmation that the work meets federal standards—not just our word.

Rebates, Incentives, and Assistance Programs

Delaware homeowners may qualify for utility rebates through Delmarva Power or PECO energy efficiency programs. Income-eligible residents can access weatherization assistance through the Energy Coordinating Agency (ECA) or LIHEAP programs.

We're an approved contractor for these programs and can help you navigate eligibility and application requirements.
