"John came out and looked at several issues, determined them to be cosmetic not structural and wrote a certified letter to that effect. We got great peace of mind from his visit."

"ESG Design was great to work with. I contacted them through Home Advisor for an impartial assessment of the cause of cracks in my ceiling, plus a few other issues. Eli, the engineer, did a thorough inspection and developed a solid plan for repairs. ESG also offered two levels of fees, which was extremely helpful for my budget. Thank you ESG for the service and peace of mind!"

"Mr. McCann came out to assess the water and carpenter ant damage to a wall and foundation sill plate of our home. He was able to quickly evaluate the problem area and provide the structural engineering report and repair task list we needed to get contractor bids on the reconstruction project. Highly recommended."

"This review is long overdue.  We can?t really express
how happy we are with our new house that Char designed.  We hired Char to
design our remodel in 2013/2014.  When I say remodel, that is a bit of an
understatement, as we took a 700 square foot house to approximately 1,900
square feet, which included adding a basement.  It is essentially a new
home, and we couldn?t be more happy with it.  We did the majority of the
work ourselves, which is one reason it?s taken us this long to sit down and
write a review.  Although having a baby 1 month before the excavators came
added a bit to the complexity of things...  The project pushed us to our
limits, and a little beyond at times, but it has all been worth it.  Our 2
year old son absolutely loves to run around and scoot across our big long
hardwood floors on his little scooter.  There is quite a runway now, and
he definitely takes advantage of it.
But back to the review.  We knew the basic idea of what
we wanted, but we needed an architect to draw up the plans.  We wanted to
hire someone local, and Char was great.  Char really knows the code
requirements which helped a lot getting the plans through the permitting
process.  We drafted up a general floor plan before hiring Char, and she
provided a lot of good ideas and helped us refine the design to work more
efficiently in the given space.  This turned out to be a lot more
important than I thought because it?s hard to visualize how a space will flow
and function from a simple floor plan.  Char also knows a lot of
professionals in the industry, which is great when it comes to engineering calculations,
truss design, etc.    
We really like the neighborhood we?re in, and it was
important for us that our new space match the character of the original
house.  You see a lot of remodeled houses that are cute in front, with a
big ugly 2-story box sticking up in the back.  We wanted to avoid this and
worked hard to make the addition look like it was always a part of the
house.  We also wanted the house to retain its ?small? appearance from the
front, and we didn?t want to use up all of our backyard either.  We ended
up with a perfect house.  Our neighbor across the street who was born
there in the late 1940?s told us he can?t even remember what the house used to
look like - he said it really just looks like it?s always been there (and it?s
only been 2 years). 
I would definitely recommend hiring Char if you need an
architect or design help.  Beyond her architectural skills, she is very
personable and easy to work with.  She came out to our house many times to
review drawings with us, go over edits, and discuss various ideas.  She
was very accommodating, and even helped us get the plans through the permitting
process.  Thank you so much Char, we really love our new house, and
couldn?t have done it without your help.

"Ward Engineering began working with Jared of Cornerstone Home Designs approximately 3 years ago to perform residential design work using Chief Architect design software. I find Jared to be the most capable Chief Architect designer I have ever worked with. Jared is very efficient and thorough at developing the residential Chief Architect models. In addition to being competent, Jared makes himself available to provide personal 1-on-1 training over the internet, which has been a huge blessing to our company and clients."

Structural Engineering questions, answered by experts

Yes, you can build over a stump if the roots are no longer alive. Living roots will continue to grow and may damage your new construction over time. Similarly, you should also remove rotting stumps because they may continue to attract pests and even cause new structures (especially those made from wood) to decompose as well.

Yes, they offer plans for repairs or reinforcements to address issues.

On average, 6 inches of concrete can hold around 150 pounds per square foot, but the exact weight that 6 inches of concrete can hold depends on factors such as the type of concrete, the reinforcement method, soil conditions below, and structural design. If you’re concerned about the longevity of your concrete patio, walkway, or driveway, hire a professional to help you choose an appropriate concrete thickness and reinforcement method for your needs.

Yes, ceiling joists are typically load-bearing. However, their primary function is to support the weight of the ceiling and loads applied to it, like lighting fixtures and ceiling fans. They can also help support the roof, especially if they’re part of truss systems. Remember, the load-bearing capacity of ceiling joists depends on the material, size, and space between them. 

Structural engineers can perform various inspections on different structures in your home. These inspections usually include a report detailing the engineer’s findings and recommendations for repairs so you can determine your next course of action for repairs, replacements, or new builds. Some of the most common structural engineering reports include:

  • Full home inspection: $350–$1,000

  • Foundation: $300–$800

  • Load-bearing walls: $300–$1,000

  • Roof: $150–$600

  • Chimney: $200–$500
