"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. "

Customers say: Quality work

"JM did a fantastic job. About 13 years ago, while living at our previous residence: JM remodeled and modernized our full Kitchen, two full bathrooms and, after many tries by other contractors, he was able to stop a leak from our roof at no charge. About 10 years ago, at our current residence , JM remodeled and modernized our full kitchen and did a unique job of updating 4 large sliding closet doors. He removed the cheap inserts, and replaced them with 1/4” high quality plywood into the frames. He then, using wood molding, he made the face of the doors look like real wood doors. Doors were stained and look like expensive oak doors! JM comes up with excellent suggestions, alternatives, and expense saving ideas. We plan on relying on his expertise when we’re ready to upgrade our Patio. All the best to JM Group!"

"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"

"After years of working with various contractors on major home improvements, we finally found our dream team with Duane Mainardi Builders! From the moment we reached out, Duane and his crew impressed us with their honesty and clear communication. Duane was always available throughout the project, and Keith, the site foreman, was simply incredible. He was onsite every step of the way and made the entire experience smooth and enjoyable. When we asked for changes after work had started, they welcomed every request with a genuine commitment to getting it just right. The siding crew was professional, skilled, and worked tirelessly. What we anticipated to be a four day job was impressively completed in just two and a half days. The final result? Gorgeous vinyl siding that has completely transformed our home?s look. We wholeheartedly recommend Duane Mainardi Builders if you want high quality siding done right by a team that truly stands behind their work. Michael and Vicki Sneed"

FAQs for garage building service projects in Whippany, NJ

A well‑constructed, properly permitted detached garage adds between $12,000 and $36,000 to a home’s resale value. Buyers appreciate the secure parking, extra storage, and flexible workspace, so appraisers often bump the property’s value accordingly. The exact return depends on the garage’s size, finishes, and how well it matches the main house, but most homeowners see a strong ROI when the build meets local codes and passes inspection.

Yes—once it meets local building codes and you secure the proper permits, a detached garage can be converted into living space. Finishing the interior, adding climate control, and ensuring safe egress effectively increase your usable square footage, though it may not always count toward the official listing. Skipping permits can trigger fines and even force you to undo the work, so always clear plans with your city first.

Most homeowners policies cover a detached garage under the “other structures” provision, but coverage limits vary. Review your declarations page and ask your agent how much protection you have for separate structures. If the limit is lower than the garage’s replacement cost, you can raise it for a modest premium. Confirming the details now prevents headaches if you ever need to file a claim.
