"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

Proper licensing and experience in residential and commercial structural projects.

The process involves initial consultation, concept development, detailed planning, regulatory approvals, and integration of contractor work for project execution.

You should pick steel for your new support beam for a few reasons. While steel is more expensive than other materials, such as laminated veneer lumber or glulam, it offers the following benefits:

  • Fire-resistant

  • Unaffected by pests

  • Longer-lasting

  • Stronger against water damage (when galvanized against rust)

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

Costs depend on unit complexity, labor, wall mounting needs, and additional accessories like floating shelves.
