"Linda was excellent! Knowledgeable, great communicator and honest. We were told structural work was needed on our 100+ year home but after a thorough assessment, Linda recommended tuckpointing only!"

"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."

"I was really under the gun due to a prior Architectural firm not performing their duties per building plan codes. Not only were the plans incomplete but the City Plan Reviewer states(The Worst plans he’s ever seen) they will not make adjustments unless there is an additional charge for Thousands. Evaluation’s saved my clients and drew our project per code, along with Engineering in less time then they quoted. I highly recommended them, Especially Kirsten. You went above and beyond trying to coordinate this project. The staff was very professional and I will use them on all my projects. Sincerely, Frank B BCM Builders"

"He was out of business because he had chosen to try another profession.  Two weeks ago he gave me a call and said he was back in business.  My brother has used him extensively and I've used him for several projects.  Now that he is back in business, I'm having him come back and do some projects for me.  His name is Daryl Fegatto.  I highly recommend him and in fact I have recommended him to others.  His license ensures free estimates, framing, roofing, siding, room additions, custom decks, trim carpentry and hardwood.  He did siding when my brother built his house.  He did my brother's basement and he may end up getting mine when that time comes.  He made my garage from 20 by 20 to 20 by 30 and he reroofed all that about eight years ago.  He has purchased some land, built homes and sold them.  He has a tendency to over build which we pay for but the projects he does is going to last.  He is not fly by night kind of operation."

Structural Engineering questions, answered by experts

A 4-inch-thick concrete slab can support around 4,000 pounds per square foot if a contractor reinforces the slab with rebar, while that same slab without reinforcements will support closer to 1,000 pounds. For the purposes of a patio, 4 inches in thickness without reinforcement should suffice unless you’re installing heavy kitchen equipment or a hot tub on it. In those cases, reinforcing your slab and sticking with 4 inches of thickness should provide plenty of strength.

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

Yes, professionals reinforce the foundation with additional supports or piers to prevent future sinking.

  • Full home inspection: $350–$1,000

  • Foundation: $300–$800

  • Load-bearing walls: $300–$1,000

  • Roof: $150–$600

  • Chimney: $200–$500
