"Terrible choice on my part. Joe, the owner, was always late, by days. Had arguments with his contracters - even in my house, in front of my wife. Constantly asked me for money. After 1 month, the job he said would take 4 days was not even half done So, I fired him and the very next day I got someone through Angi who finshed the job in 3 days. And it looks great."

"***BEWARE*** Do not hire this firm because if they find something wrong, they will turn you into the City Building Inspector. My house is for sale and in the buyer's inspection, a crack in the foundation needed further assessment. I hired ACE based on internet recommendations to assess this foundation crack. I spoke to Doug on the phone several times prior to our meeting and he seemed great. Prior to the site meeting, I had said that the buyer would be there so if he saw anything really bad to speak to me in private about it. He said that he worked for me and wasn't comfortable with the buyer being there and would not address anything in front of him. When he met me at the house, that all went out the window. He said that the foundation crack was not an issue but he found some other things that he didn't like. Now keep in mind, I only hired him specifically for this foundation crack. He assessed a underground concrete garage roof, which on the top also doubles as one entry point for the house. He said it wasn't safe and basically was going to collapse. And it was going to call the City Building Inspector to report this. Now I was flabbergasted. I had no idea there was any issue with this roof. I pleaded with him to not call the city officials because this was the first I was hearing about it and to give me a chance to repair. He said it was against his ethical code. He also told the buyer to basically run away from this sale because there were major problems. This was an as-is sale so ACE had no right to provide their opinion after we had hired ACE directly. Once ACE left, I called a concrete contractor immediately to assess the roof. I met the contractor the next day and he basically told me that it was not in any danger of collapsing. ACE forwarded the engineering report to the city building officials who put a lien on the property based on "Unsafe Conditions". I spoke to the building inspector who said he agreed that it was in no danger of collapsing but since they have a stamped engineer report, they had to write me up. I had to hire another engineering firm to assess this garage roof and draft plans for the work to be done. This literally cost me the sale of the house and more than $10K in repair work. DO NOT HIRE THIS FIRM!"

Structural Engineering questions, answered by experts

Yes, floor joists are essential structural components. They support the weight of floors and everything on them, transferring loads to the foundation and walls. Properly installed joists are necessary for maintaining strength, stability, and structural integrity.

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. 

Signs of structural damage include foundation cracks, roof leaks, bouncy floors, crumbling concrete, and cracked or leaning chimneys. Structural damage can make itself apparent in various ways, and sometimes, there may not be obvious signs. Inspect your foundation and roof annually to stay ahead of potentially serious structural problems. 

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

The essential difference between an architect and an engineer is that architects typically focus more on the aesthetic design of buildings, although not without consideration for the structural integrity of the building. Engineers focus more on the structural, technical, and practical aspects of whether and how an architectural design can be built as drawn. You may need to hire both types of professionals if you’re designing and building a new home.
