"KATZ DESIGN & BUILDERS 10313 Los Alamitos Blvd, Los Alamitos, ca 90720 Rating 1 * for a WRITTEN and SIGNED contract of $13,000, the bill changed to $14,835. Stay away from KATZ DESIGN & BUILDERS in LOS ALAMITOS. I would give it a zero star if that was an option. Most dishonest company we have ever hired. Our kids’ house needed to have a fire pit filled in. KATZ sent an employee named VAL in person to discuss of the work that needed to be done. VAL wrote a contract which we agreed upon, of the amount of $13,000. Mid way through the project, VAL sounded very upset and told us that he must charge us $1,835 more if we want the job finished. Val then gave us a new invoice, a total of $14,835. We were 7 hrs away on a car trip. VAL actually asked us to leave him a positive 5* rating, after jacking the cost of the job up considerably. Furthermore, one worker brought while working at the site. We got back the next day, contacted the KATZ office and spoke to CHERYL who acted completely surprised that VAL has given us a contract with the extra charge. CHERYL indicated that she would talk to the PRESIDENT and VAL to straighten everything out. We then received a PDF file, written by the PRESIDENT and VAL , indicating that our kids’ house would have a MECHANIC’S LIEN placed on it we did not acquiesce and pay the additional amount. We are retirees but for nearly 30 yrs, we too had business where we never advertised and never had to. Business came to us by word of mouth and a sterling reputation. If we were to have run our business as dishonest as KATZ DESIGN & BUILDERS appeared to have been, we would have been out of business. We heartily do NOT RECOMMEND KATZ DESIGN & BUILDERS, AS THEY ARE THE MOST DISHONEST COMPANY."

Structural Engineering questions, answered by experts

A structural engineer’s report is almost always worth it, as it can help you avoid buying or overpaying for a home with structural issues. The most important thing the report does for you is provide peace of mind that you won’t have to pay thousands of dollars for structural repairs right after closing on a property.

The National Association of Home Builders requires repair of any foundation crack of more than one quarter of an inch, although local regulations may vary. In general, any visible crack that is growing in size, allowing water through, or that you have just noticed, is a good reason to call a structural engineer. Cracks can be a sign of a sinking foundation, so an inspection is a good idea for your peace of mind.

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

Costs depend on material choices, labor, and the extent of structural modifications.

A structural engineer evaluates any structural components, like floors, foundations, walls, and roofs, to ensure they can support the structure. They also consider the soil quality in your area, potentially extreme weather conditions, and proximity to bodies of water and groundwater to ensure your building can withstand any stresses placed on it by the surrounding environment. Structural engineers work on both new and existing buildings.
