"Merrie Ann Cullin was very professional and took time to understand what our needs were and met them 100%. She took time to dig deeper and confirm details of construction and design of our addition to allow for efficiency in completing the project in a timely manner. I appreciated her genuine care and concern that we received a design we wanted. Thank you."

"I got lucky. I found Lynn on a website and he was the only one with all 5 stars...now I know why! He was so wonderful to work with; knowledgable, responsive, and patient as they come. He worked within my budgetary requirements and even recommended a builder that I decided to work with. I cannot say enough great things about Lynn and highly recommend him to anyone looking for the best architect! If I could give him 10 stars, I would!"

"Clear specific recommendations to stabilize and correct sinking foundation & leaning walls on my 100 year old solid brick garage. Will implement recommendations. Although engineering report was promised within 7 to 10 days of inspection, it was received in 25 days. Worth the wait, great overall experience."

"It started very well, we worked with Tara, she was very receptive to the changes that we made and was very accessible and flexible.We wanted initially to hire for full remodel, but their quote was too high ,so we decided to limit only to cabinets and install. We hired other companies and it was a smart decision . Then the installation came and unfortunately it was poor planning and what was very disappointing poor execution leaving us with significant gaps between the back of the cabinets toe kick and the cabinets.. nails trough the cabinets and misaligned doors When we alerted about it..we were told to hire someone else to fix that ..I must admit that the quartz company that did do very good job. But in regards with the cabinets installation no supervision and very poor craftsmanship. So we ended up with having to repair what should have been planned and executed well initially."

"Tim is amazing. I was days from closing on a house when the underwriter decided a structural engineering report was required so I called and spoke with Tim on a Wednesday evening, met with him Thursday morning and had a report in my hand by Thursday at noon, less than 24hr turnaround! Needless to say Tim really helped me out and was very courteous, knowledgeable and professional. He will always be my go-to structural engineer."

"Ed responded to our request for a structural engineer consult very quickly, and was able to come out and give us a consult within 2 hours (and on a Saturday). His assessment of the detached garage walls of a home we are about to buy provided both us and the sellers much more peace of mind in moving forward with the deal; he provided options that would likely be more permanent (which is what we wanted) and cost less to repair, and represented the objective opinion we needed. All the contractors we had talked to were just confusing and upsetting us with differing recommendations and cost estimates. We highly recommend Ed Brenkus..."

Structural Engineering FAQs, answered by experts

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

Dormers must be able to bear the load of their own construction and the added window. The style of the dormer, however, will determine where the weight loads onto your home's structure. A gable dormer bears the weight on the side walls whereas a shed dormer bears it on the front walls.

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.

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. 

The 10 10 rule describes the formula most contractors use to determine how much to charge for a job. Allowing for 10% overhead above the total projected cost to do the work and 10% profit sets a contractor up for success, even if there are delays or other problems on the project. This formula isn’t a hard-and-fast rule, but it is a ballpark figure to begin with when estimating your expenses on a job.
