"Angelo & crew were excellent! Grade A quality of work, extremely polite, and just a pleasure to work with. They completed our addition in a time manor and we could not have been more pleased with the outcome. We HIGHLY recommend Joseph and Sons for any project and we will never use another company to do any work in our home other than Joseph and Sons. Thanks Angelo!!!"

"My parents and I live in a old brick apartment building in Hoboken that is from the 1880s. The bathroom in our apartment had not been updated since the 1940s. We needed help ASAP. We checked out Cesar s page and wanted to hire him immediately. The reviews speak for themselves. When he came into our apartment to give us a quote we knew that this was contractor we needed to get the job done. Cesar is affordable, friendly, and very accommodating to any issues or concerns you have before starting the project. Two massive issues with our project were that my dad has spinal & walking issues, so we needed the floors clear of all tools and materials at the end of the each day so that father could walk efficiently through the apartment. The other big issue was that we only have 1 bathroom, so Cesar agreed to work with us on pulling the toilet off and on as every day finished so that we did not have to leave our building to use the toilet. Him and his crew are the best and take pride in their work so that owner is happy with the final result. We brought the bathroom down to the bare bones and rebuilt it back up. I worked with him every step of the way to make sure that he needed all materials to get the job done in the time we needed. This project was an intense remodel with some of the hardest demo and substrate materials that an old bathroom can have. He didn t think anything of it. He has veteran experience in the field and this remodel only took 3 weeks. We are very impressed with Cesar s craftsmanship and professionalism and we will be hiring him again for any future interior projects."

BUYER BEWARE.  I hate long reviews...but I wish someone rang the warning bell with a review of their experiences before we used Ernest & Sons.

To be fair In the end the job was done--but at what cost?  We worked with Jose a few years back to replace our driveway.  Jose and team did an excellent job.  So when we wanted to have our patio and walkway done we called Ernest and sons again.  This time we dealt with Ernest.  Initially he was nice and helpful showing me other patios completed.  We were very specific on timing to finish the project he was in agreement understanding weather delays could impact the completion. 

Once the contract was signed ...communications on their side stopped.  We had to call several times to see when the project would start. Once the job started the guys on site were nice but they did not speak much English and there no project manager to check in to see how things were going. 



When the job was done there was light rain and we noticed pools of water on the patio.  I put paper cups in the standing water and took pictures.  I contacted Ernest he came out and never conceded there was a problem as he looked at the standing water.  However he sent a crew back (again we had not paid yet) to remove the pavers and ensure it was level. They removed pavers in different areas 5 TIMES to level the patio.  While I truly appreciate their efforts...why didn't the first crew simply get it right.


DAMAGES TO OUR YARD AND NEXT DOOR NEIGHBOR.  In the process of building our patio they drove trucks onto our yard

and the neighbors damaging both yards.  I immediately took pictures and called Ernest--he assured me all damages would be taken care of.  When the job was complete his guys put seeds down and we paid in full.  However almost a month later there were only spots of grass and both yards still damaged.

I called again sent more pictures and he sent another crew that told my husband they were putting  down the 'good stuff this time' (really). We watered the lawns twice a day same as before...the damage is still there are now we have to pay out of pocket to fix our lawn and our neighbors! 



ICING ON THE CAKE.  Company called and asked if Ernest could bring a potential customer to see the patio. My husband agreed assuming he could talk to Ernest about damages.  Ernest was no show...they gave the prospects our address...and to our surprise two strangers walked into our backyard without even ringing the doorbell. I do not fault the couple but Ernest and Sons for handling this entire job so unprofessionally.

If you still choose to use this merchant ...good luck and get in writing how damaged will be handled.

FAQs for addition to existing structure building service projects in Randolph, 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.
