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 client's 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."

Expanding your house is a major undertaking. Not only are you altering your existing exterior walls, you are most likely adding new electricity, foundation, and plumbing. Even planning a room addition needs a lot of groundwork before construction begins.

Home addition companies know how to plan, construct, and finish any room and can even add a second story to a single story house. Find local contractors who will work with you to:

  • Make the best use of your existing floor plan and supports.
  • Build the new electrical connections and plumbing to code.
  • Incorporate the existing foundation for better stability and reduced settling.
  • Register the addition with your county according to local regulations.

A reliable home addition contractor can make sure your new addition is safe. They can also ensure the construction goes smoothly from start to finish. Enter your zip code and HomeAdvisor will connect you with prescreened home addition contractors near you.
