"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!"

"It was a pleasure working with Johnson Custom Builders. Ryan was very professional, honest, and transparent. He studied the plans and specifications crafted by my architect in great depth and provided a detailed cost estimate. He also took the time to walk me through how the custom house build process will work and the expectations I should have. Overall a great experience for me working with Ryan."

"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.

"Josh has always been prompt and communicative with every interaction we've had. I initially got in touch with him about new construction design questions, and when we discovered that our current home porch posts had rotted through due to faulty design by the original home designer, Josh jumped into action. He had his engineer and construction crew to our door within 24 hours to take a look and put together a plan. He took my design ideas and brought them to life. He was transparent about all parts of the cost (to include his profit), and gave us to option to lower the cost by hauling away debris and painting the porch (which we were more than willing to do). Any delays with the work were met with a phone call and followup email if he didn't get through to either my husband or I immediately, and the construction crew did very high quality work. We were beyond pleased with his customer service! We will definitely use Revival Home Designs in the future when we decide to build our forever home."

"I am having a full master bath and kitchen remodel done with new layouts in both rooms and knocking out a wall. Evolution worked with me to quickly get a drawing done of the new layouts so that the contractor could get started on the project. They made sure to include me in the process so that the design would be done exactly as my wife and I envisioned. They communicated effectively throughout the process and were always courteous and professional. I recommend them to anyone with drafting needs."

Structural Engineering questions, answered by experts

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

A structural engineer's report provides a professional assessment of a property's structural condition. It typically includes an evaluation of the foundation, key structural elements like roof trusses, floor joists, studs, beams, and rafters. The report will also contain a detailed description of the engineer's findings, often supported by photographs, and provide recommendations to correct any identified issues. Depending on the scope of the inspection, it might also include an assessment of property drainage, potential issues from environmental conditions like extreme weather or tree placement, and an estimated time and cost for any recommended repairs.

The average cost to hire a structural engineer is about $550, with prices generally ranging from $200 to $1,500. Structural engineers may charge a flat rate, by the project, by square footage, or an hourly rate, which is typically between $100 and $250. Many jobs, such as inspections and structural calculations, are billed at a flat rate, which often falls between $300 and $800. The final cost depends on several factors, including the project's type, scope, size, complexity, ease of access for inspection, and your geographic location.

If you’re building new construction or adding onto your existing home, hiring a structural engineer is not only worth it but it’s probably required by your local building department. Structural engineers will ensure you aren’t making your home unsafe in the building process, which is crucial from a safety perspective but also a legal one. It’s also worth hiring a structural engineer if you’re making changes to structural components, like removing a load-bearing wall.

Proper licensing and experience in residential and commercial structural projects.
