"My review of the work I have had done by Thomas Gianni & Sons Inc.. They really did a great job of working on my property. I call their office and asked to get some excavation of removing a couple of tree stumps in my yard and to put down approx. 20 yds. of gravel in an area near my shed. It was just about three or four days and they call me back to confirm to come out the next day, June 22. Their employee came by early in the morning and went over all the project. Figured out what equipment he needed and measured up for the materials and started the work about an hour later. He was very cautious and caring about minimal damaging to the yard. After removing the stumps he graded the surrounding area with the machine to the point where I only needed to rake it out to plant new grass. The gravel was put down flat and clean; not a mess. I would definitely hire them again."

FAQs for doors (exterior) installation and replacement projects in Derby, CT

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.
