"I was long over due on doing a addition/ remodeling project on my house. I had Victor come out and I went over what my plans were and what I had envisioned. He was quick to offer solutions that met the cities guidelines, which meant part of my addition would be 2 stories, to allow room for my master suite. They prepared the plans worked out all the details with me. The scope of our project was; adding a master suite, enlarging the family room, kitchen remodel, powder room remodel, and some other misc. work. I was pleased with every aspect of there work, from customer service to the quality of the work preformed. One thing I was really impressed by is the attention to details. Victor would spend so much time talking to me about little design elements, how to position the lights, where to put switches, all things which I thought were pointless at the time. But now I realize all those little things really do add up to make a great finished product. All around it was a pleasure working with Build Now NYC"

Structural Engineering questions, answered by experts

Any issue that affects the structural integrity or soundness of a home is considered a structural issue. In addition to foundation cracks, other signs of structural issues include roof leaks, bowing walls, sloping floors, gaps around windows and doors, and more.

Yes, unresolved damage can decrease property integrity and market value.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

Structural engineers specialize in all aspects of a building’s structural integrity, including the foundation. Foundation engineering is a critical part of structural engineering, so structural engineers are experts in foundation design. Many foundation repair companies either have a structural engineer on staff or one they work closely with, so be sure you look for that when deciding who to hire for foundation repair.

Costs depend on furniture type, size, complexity, and whether additional modifications are needed.
