At LEVEL, we are committed to common sense, real-world solutions. We pioneered LEVEL because, after years spent exploring all disciplines of civil and structural engineering in the building industry, we continually encountered the missing fundamentals in our own trade. These lost elements of service culture & exceptional business practice inevitably cost owners & entities untold stress and frustration; contractors lost time & money, realtors & lenders were left unable to satisfy their clients' needs. We concluded that our capacity for A&E services could function at a higher level, thus, LEVEL Engineering & Inspections was founded. We serve your interests & provide knowledgeable, expert design, inspections, analysis, forensics, recommendations, and reporting. Whether your need is for permitting, forensics; new, remodel, or repair engineering designs; foundation problems; civil or architecture - let us help you navigate your Civil, Commercial, Residential Structural Engineering needs.

We are a family owned and operated business with over 40 years of experience in the remodeling industry. We are fully licensed and insured in NYC, Nassau and Suffolk counties.

"I don't think contractors come any better than this one. Tom was professional throughout, meticulously explaining everything to us at every step of the way. You should hire this guy for his communication skills and customer service skills alone. Not only was he responsive to our texts and calls -- he himself was proactive and constantly in touch with us about the schedule and the work. And the quality of the work is great. You can tell when there is pride of craftsmanship. Tom does a lot of the work himself but when he needs to subcontract, the people he hires also seem to be serious craftsmen. Our final cost for the work was more than the estimate but you have to be naive to expect that when you embark on something like this that there aren't going to be a few surprises. Whenever one of those surprises cropped up (crumbling 100-year-old sewer line, for example), Tom informed us and laid out all the options for us. Definitely hire him! I know we will, again, when we need major work."

Structural Engineering questions, answered by experts

Cathedral ceilings make a statement in your home, but at the cost of your attic space. Normal attics are wide open, which allows warm air to move around and exit your home. Because of this, cathedral ceilings make your home less energy efficient and put your ceiling at risk of venting issues if you’re not careful. They also reduce your attic storage space, potentially cause an echo, and even make it harder to change a light bulb.

Yes, walls on the top floor can be load-bearing if stacked on the floor’s foundation.

Structural engineers are necessary for projects involving alterations to load-bearing structures, foundation work, and compliance with safety standards. This includes home expansions, retaining walls, and significant repairs that impact a property's integrity.

Yes, they offer plans for repairs or reinforcements to address issues.

All foundations have footers, including monolithic slabs. In some cases, the foundation itself acts as the footer, as in the case of a floating slab and a monolithic slab. With a monolithic slab, the footers—which are just the bottom-most portion of the foundation that distributes loads down to stable soil—are a part of the main slab and are constructed with a single pour.
