J Welch Engineering is a single person firm with ten years of experience in Structural design.

"Josh came out for an hour to talk through how moving the staircase might go. He was polite, professional, prompt. I paid him for an hour of his time ($125). I ended up using a different structural engineer because Josh was booked 13 weeks out and I wanted to get my permit more quickly than that. His overall quote for the work was around $1000, which seemed very reasonable to me. He was patient when answer all of my MANY questions. He was very understanding and polite when I told him I would be using a different engineer."

We specialize in new additions, interior or exterior home renovations, including bathroom and kitchen remodeling, home additions,roofs, granites, garages and more!

"I cannot express enough how unsatisfied I am with the ER Eliete Remodeling Services, LLC and the services provided by the general contractor I hired for my home renovation project. From start to finish, the experience was nothing short of a nightmare. I regret choosing them and would strongly advise others against making the same mistake. Poor Quality Workmanship: The quality of their work was abysmal. The finishes were sloppy, and it was evident that they lacked attention to detail. I had to point out numerous mistakes and flaws that should have been caught during the construction process. Unprofessional Behavior: The behavior of the contractor and their crew was unprofessional and disrespectful. They yelled at my wife, and constantly said we are to picky Lack of Expertise: It became apparent that the contractor lacked the necessary expertise to handle certain aspects of the project. They made numerous mistakes that had to be fixed, causing even more delays and frustration. Had to pay others to fix their mistakes. In conclusion, my experience with this general contractor was a complete disaster. Their lack of professionalism, communication, and expertise resulted in a poorly executed project that was overpriced and far from meeting my expectations. I strongly advise anyone considering hiring this contractor to think twice and explore other options. Save yourself the headache and disappointment. Two weeks after he left our home, we had a major plumbing leak, that required walls to be opened up, more money spent to correct his problems. ER Elite Remodeling will take your money, and either do a poor job or walk away with project not finished, not take your phone calls or texts, but gladly keep your money. Found out later that license is expired...................."

Structural Engineering questions, answered by experts

Cathedral ceilings make a statement in your home, but at the cost of your attic space. Normal attics are wide open, which allows warm air to move around and exit your home. Because of this, cathedral ceilings make your home less energy efficient and put your ceiling at risk of venting issues if you’re not careful. They also reduce your attic storage space, potentially cause an echo, and even make it harder to change a light bulb.

The easiest way to tell if a wall is load bearing is to check if it’s an exterior wall or if it runs perpendicular to the joists above and below it (or parallel to beams). Exterior walls are almost always load-bearing, and walls that run under beams or parallel to them are also usually load-bearing. There are exceptions to these rules, and walls that don’t fit into these categories can still be load-bearing. If you’re unsure, hire a structural engineer to look at your home to assess whether or not the wall is structural.

Generally, you can tell if a home is bolted to the foundation by checking the foundation for plates. If you see that your foundational plates connect to wood or bolts protruding from them, this means that you have a bolted foundation. However, it's always wise to bring a home inspector in to confirm if your foundation is secure.

Trusses and rafters each have advantages and disadvantages, so one isn’t necessarily better than the other. For example, trusses are more affordable and often come in prefabricated kits, so they’re easier to build than rafters. However, rafters are available in a variety of designs, so it’s easier to find one that fits your style preferences. Plus, if you want to build an attic at some point down the line, it’s far easier to do that with rafters rather than trusses.

Structural engineers typically charge between $100 and $250 per hour, but many jobs won’t be based on a per-hour fee. Instead, the structural engineer will offer a flat rate for the inspection and structural calculations. The flat rate for a structural engineer costs an average of around $550, but you could see prices ranging from $300 to $800, depending on the complexity of your project and how easy it is to access certain parts of your home for the inspection.
