"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"

"Just a few years ago, we hired Double D to remove all of the old bright yellow siding (40 years old) and remove both layers of old roofing. The goal was to replace the roof and figure out the best options for us regarding the siding. The owner came out, met with us, presented options and associated costs quite clearly. Ultimately, we choose a lovely shade of sage green siding and a gray roof. We could not be happier. The employees were polite and efficient. The work was done in a timely manner (less than two weeks) and still looks great. We had zero problems with Double D. I plan on using them again to update a section of the siding that had previously been covered by a back deck. IMPORTANT NOTE: My neighbors replaced their siding with another company even though we advised them that Double D’s pricing was spot on and extremely professional, with attention to detail. Five months after their siding was installed, huge swaths of siding fell off! And their contractor was no where to be found. That’s when they asked for Double D! You will not regret utilizing Double D and will appreciate the variety of services available."

"Flansburg Construction just renovated our second floor hall bathroom and we could not be happier with the results! When setting out on this journey, we received three contractor estimates. Although they were all comparable in price, Dan's group was by far the most responsive and the most helpful. What set Flansburg Construction apart from the others initially was the fact they provide a designer. Bernadette was invaluable in the process. Once she had an idea of our style, she made product selection easy by narrowing down options for us and all the while maintaining our budget. Also, where other contractors required that we order and be responsible for all materials, Flansburg took responsibility for all, which was such a relief! Once construction was underway, everything went more smoothly than we could have expected. The workmanship exceeded our expectations and our project manager provided progress updates daily, in addition to letting us know what to expect the following day(s). He was also very responsive to us and was patient when explaining the work. Everyone associated with the project was kind, courteous and extremely neat. We highly recommend Flansburg Construction for any renovation needs and will call upon them again ourselves with any additional projects we may have in future."

"Eddie owner of Del Val Electric is a crook and unprofessional he was contracted to do several jobs at my home to Repair an outside light post, Repair electrical outlets and light in sunroom, and basement, install chandelier reciprocal and sconces and install cable wiring, plus install three doorbells and Door chime. The contracted price was $2500 he did less than half the work was paid in full and changed the parameters of the contract to time spent which was never discussed. He promised to complete the job and did not he cancelled 5 appointments to finish the job and when I complained he told me to go F%$# myself. My mistake was to trust this individual and pay him in full, I will need now to take him to small claims court for a partial refund. Do not use this contractor you have been warned!"

FAQs for garage building service projects in Allentown, 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.
