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.

"Engineer was highly knowledgable but more focused on permitting and administrative issues than the engineering issues."

"At first everything seemed GREAT. I gave them a 10 out of 10 review in 2024. Santos comes across as an authentic caring person with great prices. That’s why it’s with a heavy heart I have to write this review July 2025. 8 MONTHS later all the work has FALLEN apart. 1. BLACKTOP the driveway. Puddles everywhere . NO restitution 2. Installed a FENCE UNEVENLY and blamed it on the ground. NO restitution 3. Didn’t finish placing ARTIFICIAL GRASS. Paid in full. NO restitution. 4. A GARAGE DOOR installed incorrectly never corrected. paid in full. NO restitution 5. His workers broke things. NO restitution. Those were the big jobs. Plenty of indoor small jobs have simply FALLEN APART. I’m a patient and empathetic person when I see how hard people work and especially in the summer heat. I waited for the promises to be filled that never came. Shame on Santos Cruz. I guess there’s always karma. Andrea Sievert Massapequa"

FAQs for engineer structural projects in Smithtown, NY

The timeframe for installing an LVL beam depends on your project's complexity and scope. Factors affecting the timeline include whether walls need removal, the beam's size, and whether electrical or plumbing modifications are necessary. Your contractor should provide a specific timeline estimate based on your home's unique circumstances and the specific requirements of your installation.

Financing options are available for structural improvements like LVL beam installations. Many homeowners use home equity loans or lines of credit, often offering favorable interest rates for home improvement projects. Some contractors partner with financing companies to provide payment plans directly. When gathering quotes, ask potential contractors about financing partnerships they maintain or recommendations for lenders experienced with home renovation projects.

LVL beams become necessary when you need to span greater distances without support columns or when supporting substantial loads. Traditional lumber can't span more than eight to 12 feet without support, while LVL beams can extend up to 30 feet. LVL provides the necessary strength to create truly open concept spaces or support upper floors without columns. Consulting with a structural engineer helps determine the appropriate beam type for your specific requirements.

Beyond the core installation, the budget for build-back costs totals $400 to $2,000, depending on the extent of affected finishes. If foundation reinforcement becomes necessary, allocate $1,000 to $3,000 per pier. Permit fees ranging from $100 to $500 should also be anticipated. For installations affecting utilities, factor in electrician rates of $50 to $130 per hour and plumber rates of $45 to $200 per hour if rerouting is required.
