"Everything went wonderfully with this company.  They were very professional, listened to exactly what my problem was, and explained to me how they were going to diagnose the problem and/or solve it before doing any actual work.  Once they started, the team (three people came) worked together like a well-oiled machine.  One was in the room with diagnostics, one was at the fuse box looking for possible problems there, and the third went into the crawlspace beneath our house to look at the physical wiring.  Once the problem was found (there was a faulty wire beneath the house that had come loose from the junction box), it was fixed and tested within minutes and another full diagnostic was done to make sure there were no other possible issues.  They cleaned up after themselves very neatly.  They also replaced the light switch with a dimmer switch at no extra cost!  Well within my budget, and came in even lower than their original (FREE) estimate!  I would highly recommend this company to anyone in the Bergen County area.

Structural Engineering questions, answered by experts

Accurate measurements, sturdy materials, and seamless integration with other structures.

According to the Earthquake Country Alliance—a public and private alliance in California that works to improve earthquake and tsunami readiness—reports that unreinforced masonry, such as stone, bricks, and hollow clay tiles, is more susceptible to earthquake damage. The mortar between bricks isn’t as stable as other building materials and methods.

Yes, you can put a doorway in a structural wall; in fact, most exterior doors are set into structural walls. The project is a little more challenging than installing a door in a non-load-bearing wall because you need a structural engineer to assess the wall and make sure it’s safe to create a wall opening. Your engineer’s report will include instructions for your contractor on how and where to install additional supports, like steel headers above the door, to distribute the weight above to the wall on either side of the door.

A construction manager is particularly useful in the case of a large-scale build with custom design elements, so it’s usually worth it to hire one. They can help manage your budget, maintain quality control, oversee timelines, and navigate unexpected hurdles. While construction managers are pricey, they can actually save money in the long run by identifying cost-saving opportunities and ensuring the project stays within budget.

Yes, an LVL beam is more affordable than the cost of a steel I-beam, totaling between $50 and $200 per linear foot as opposed to the $100 to $400 per linear foot you’d pay for a steel I-beam. Not only is the wood material more affordable than steel, but it’s also more similar to traditional wooden beams and doesn’t require as much retrofitting to connect joists.
