At Harmony Home Improvement, we have built our reputation in Connecticut by focusing on high-quality, factory-certified installations, strong manufacturer relationships, and consistent customer satisfaction. We choose the product lines we install carefully, and we stay current with training on those product lines so we can stand behind our work with the best warranties in the business.

We are a GAF Master Elite® roofing contractor and maintain additional certifications across siding and exterior products to ensure every part of your home’s exterior is handled correctly.

GAF Master Elite® Contractor

GAF is one of the largest roofing manufacturers in North America, and their Master Elite® certification is only awarded to a small percentage of contractors.

To maintain this status, we must meet strict requirements for:

• Proper installation practices
• Ongoing professional training
• Proven customer satisfaction
• Licensing and insurance compliance

This certification also allows us to offer enhanced warranty options that aren’t available through non-certified contractors.

Siding Certifications & Exterior Expertise

Exterior work goes beyond roofing. Proper siding installation plays a critical role in protecting your home from moisture, air infiltration, and long-term structural issues.

Harmony Home Improvement holds the following siding credentials:

Mastic Preferred Contractor
This designation requires verified experience, proper licensing and insurance, and a strong track record of customer satisfaction. It reflects our ability to install Mastic vinyl siding systems correctly and consistently.

CertainTeed Master Craftsman (Siding)
This certification is earned through formal training and testing in vinyl siding installation. It requires a commitment to proper installation techniques and adherence to CertainTeed’s standards and code of ethics.

These certifications ensure that when we install siding, we’re not just improving appearance — we’re protecting the structure of your home.

EPA Lead-Safe Certified

For homes built before 1978, proper handling of lead-based materials is the law.

Harmony Home Improvement is officially EPA Lead-Safe Certified, which means:

• We follow strict safety protocols on applicable projects
• Our team is trained in lead-safe work practices
• We protect your home and family during renovation work

What This Means for You

Certifications are only valuable if they translate into a better experience for the homeowner.

For our customers, that means:

• Work done correctly the first time
• Clear communication throughout the project
• Access to stronger warranties
• A contractor who stands behind their work
