"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 heรข s lucky he hasnรข t been charged with nothing. Only reason that happened is because I wouldnรข t pursue charges. He obviously is a drug addict and has a problem so maybe he should get help Possibly isnรข 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"

Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests, and make their concerns the basis of our business.

"I had an old refrigerator, microwave and some other things to be removed from my backyard. Robert was the original guy I I contacted. We talked pricing and then arranged a Time for pickup. Vinny was the worker that came out on time I may add he introduced himself and got straight to work it took him about not even 15 minutes to get all the stuff on the trailer. We talked for a bit and he informed me that they were a construction company that also did repairs and to keep them in mind if I ever needed anything which I will I've added them to my contact list. I think Robert and Vinny are phenomenal guys. They were both professional and friendly at the same time. I gave them five stars but that really not enough to describe how they made me feel like a special and valued customer.

FAQs for addition to existing structure building service projects in Mountainside, NJ

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
