"Major Homes exceeded our expectations. Paul, in particular, stood out for his meticulous attention to detail and flexibility. He graciously scheduled our first meeting at a time that suited our convenience, where he went above and beyond to discuss industry standards and align them seamlessly with Major Homes' own high standards. His dedication to ensuring that every aspect of the project met our requirements was truly commendable. Anthony was exceptional in outlining the details and expectations for the execution of the contract. He provided clarity and assurance, laying the groundwork for a successful collaboration. What truly impressed me, however, was the performance of his crew. Their professionalism and dedication to delivering outstanding results were evident in every step of the project. From the outset, Paul and Anthony showcased a level of professionalism and expertise that truly set them apart in the industry."

FAQs for doors (exterior) installation and replacement projects in Centerport, NY

Modern steel doors incorporate protective coatings and finishes that significantly reduce rust potential. These treatments create effective moisture barriers when properly maintained. Small scratches or damage should be promptly addressed with touch-up paint to prevent moisture from reaching the underlying metal. 

Doors in coastal or high-humidity environments benefit from additional protective measures and more frequent inspection. With proper care, most steel doors resist corrosion for decades.

Steel doors provide superior resistance against forced entry attempts compared to fiberglass alternatives. The inherent strength of steel creates a formidable barrier that resists impacts and tampering more effectively than composite materials. 

While high-quality fiberglass doors offer reasonable security, steel provides an exceptional strength-to-weight ratio and structural integrity. For maximum protection, look for steel doors with reinforced strike plates and multi-point locking systems.

Most manufacturers provide warranties covering manufacturing defects for periods ranging from five to 15 years, depending on the product line and quality tier. Hardware components often carry separate warranty coverage, often for shorter durations. Installation services may include workmanship guarantees covering proper fitting and operation. Always review warranty documentation carefully to understand coverage limitations and maintenance requirements that might affect warranty validity.

Provided your existing wood frame remains structurally sound and properly aligned, professional installers can often adapt a steel door to fit. The process requires careful measurement and potentially minor modifications to accommodate the new door's specifications. The frame must provide adequate support for the heavier steel door construction. A qualified installer will evaluate your current frame's condition and recommend appropriate adjustments to ensure proper function and security.
