"Angelo & team were amazing to work with. From design to implementation, it was a smooth experience. We had the same crew working at our house every day- the guys were friendly, polite, tolerated my 5 year old daughter asking them what they were doing each day (LOL). Their work was top notch- no corners cut. Every day they left my house clean, nothing left out- all materials put away and the rooms were safe for my kids and dog to be in. We couldn’t be happier with the work done. "

"Roberto and his team helped us select, paint, and install a large custom french door for our home office. Roberto understood our vision, made the process simple, and handled the project efficiently. Roberto was quick to respond, and showed up exactly when he said he would to make sure his team was on time and understood what we wanted. We are so happy with the way the door came out, and highly recommend Roberto and his team at Monk's."

"I gave this man $3000 which was 33% of the job upfront. Was supposed to give him 33% at the halfway part And 34% upon completion. But when I went to my bathroom and realized you left drugs in my bathroom and I have small children. Not like that 3000 black and small cleaners caught easy and heâ s lucky he hasnâ t been charged with nothing. Only reason that happened is because I wouldnâ t pursue charges. He obviously is a drug addict and has a problem so maybe he should get help Possibly isnâ t the option maybe rehab is. If you paid for supplies, you got ripped off wait 10 years and it will all fall apart charges for certain stuff but buys different stuff so he can use the extra money to pick himself up drugs without nobody noticing, I am so terribly in grief over this. $3000 he ran off with how is Matt doing in business and not in a jail cell"

"To begin with the salesman told us most of the work would be done outside. Also the molding did not have to be removed. This was all wrong information. They did most of the work indoors. They did not put anything down on my runner or my wood floor. My runner and floors had to be steam cleaned. They destroyed the molding around the windows. The caulking is horrible. They were supposed to send us a survey. It was never sent to us because they knew we were not happy. No one from the company contacted us to see how things went. We have to call a finish contractor to replace the molding. This is not acceptable. I do not recommend this company. "

FAQs for doors (exterior) installation and replacement projects in Dover, NJ

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.
