"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"

Our mission starts with how we propose your custom new home building construction project. We want and prefer you see the phase-by-phase costs we incur from permit to clean up. When you receive our proposal, you will notice that we proposed a cost plus a fee pricing, usually referred to as just “cost plus,” or “open book”. This is defined by adding two components together: Costs the builder incurs to deliver the scope of work + Builder’s fee for delivering the scope of work at builder’s cost. Open book provides the transparency missing from a lump sum price. It allows you as the client, to share in the benefits that come from 0% markup on material and subcontractors. Every two weeks you receive and budget vs actual spreadsheet allowing you to apply savings to other scopes that may have been cost prohibitive. We as builders pass project savings to you, our fee is transparent. See the video for more...https://www.youtube.com/watch?v=XnuIc3GrBWA

JAC is committed to doing superior work, without exception. We've purposely remained a smaller company, as it's better to have fewer jobs and do them well than to have a ton of work and be average. This philosophy is a big reason builders and home owners come to us. Simply put, we're really good at remodeling homes. The reputation our company has is built on exceptional work and an outstanding attitude. Before we get to the meat of a project, we get all our ducks in a row. That's what makes our work stand out.

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