Customer Reviews

"I met Matt Mazur from O'Danny Boy builders during a roof inspection for suspected hail damage. During the initial meeting he documented what he thought was valid hail damage and recommended I get an inspection done by my insurance. That was done and swiftly denied two days later by my insurance (official response was ZERO damage found). I requested a reinspection and asked that Matt be present to go over the findings together with the insurance company inspector. During the second inspection of the nearly identical area that was previously examined (by the same inspector from the insurance company), Matt and the inspector noted 19 findings. The next day after the inspection was submitted the roof was magically approved for replacement. I credit Matt for working closely with the insurance company and moving the process forward towards a new roof replacement. I have been very pleased working with Matt and the O'Danny boy builders company so far throughout this process!"
"The workers damaged the metal work around our brick, up the roof line and a bay window. Initially they said they didn’t cause the damage but then owned up to it. After 2 attempts to fix it, it got worse each time. The bent and dented metal is so apparent - it’s embarrassing. We have another company hired to redo the metal work, paying for that out of our pocket. O'Danny Boy owner did stop by, said he would have it taken care of. We appreciated his time, but the field manager didn’t think our concerns were apparently valid. He ignored our concerns and didn’t care that his workers did a below average job on the repairs. He was also extremely disrespectful to my wife, talking down to her just for asking a question. Our experience was not a good one."
