"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"Structural Engineer Ehab contacted me about my residential property inquiry. He had already reviewed my property and the general situation I was inquiring about when I called him back. We spoke to me about his concerns with the project and answered all my questions over the phone. He was excellent to work with. Professional & Knowledgeable. Would highly recommend reaching out for technical issues concerning residential engineering. The reason he wasn't hired was that he provided feedback that dissuaded us from taking on a costly project that would not have achieved our stated goals. I will definitely reach out to Ehab in the future prior to beginning any major residential addition or remodel."

"I contacted Geotechnical, Inc. over the phone and immediately knew that they are the right team to help me complete my projects. My main contact at Geotechnical, Inc. was Engineer Mr. Nadim S. who was very knowledgeable, subject matter expert, professional, and best off all had great communication at all stages of the project status. Mr. Nadim, is also credit to saving me tons of rework, he made sure that the engineering team I hired to do the architecture/structural design adhered to sound engineering principles and safety standards. Geotechnical, Inc. saved me tons of rework and ultimatly money. I would definitely work with Geotechnical, Inc. in the future and highly recommend them to others. I do not usually leave reviews however Geotechnical, Inc. has earned my respect and deserve the feedback."

"Our home had an outdated layout. All the different living spaces were closed off by walls. We wanted an open concept from the living room to dining room to kitchen. After interviewing several contractors, we felt that Pacificland Constructors better understood our needs and their price fit our budget.
Martin and his crew at Pacificland Constructors came in and did an outstanding job! The
first thing that they did was place up plastic ?walls? to block off the dust to the rest of
the home. They also laid down two layers of thick cardboard paper on the ground too
prevent the existing floor from being damaged. After the prep work, they quickly
removed the two non-load bearing walls. Pacificland hired an engineer to do the
structural design of the load bearing beam that would be used to support the roof and ceiling in lieu of the existing wall. A temporary wood wall was constructed to support
the existing ceiling and roof while the crew removed the existing walls. Next they
installed the structural beams, wood posts, and the metal connectors. After the beams
were set in place, the temporary wall was removed.
Once the flush ceiling beams were installed, came all the easy finishing work. The crew
moved all the existing electrical outlets and switches to adjacent walls, installed the
drywall and did the rough taping, and closed up an existing window. Pacificland
Constructors was done in 5 days and did a great job cleaning up the job site. Whenever I
had a question all I had to do was either call, text, or email him. He was very accessibly
and helped answer all my questions during the construction process. I would definitely
recommend and use him again for future projects.

"Design Everest was fast and professional. They got us the structural engineer report while we were in a time crunch. They are a little pricey but I would recommend them for their work. Thank you!"

Structural Engineering questions, answered by experts

No, squeaky floors do not always mean there is structural damage. The noise is often caused by friction from issues like loose floorboards, gaps between the subfloor and joists, or loose subflooring. While many squeaks are harmless, persistent or worsening noise could indicate a more severe problem. If you notice other signs of structural damage—such as soft or sagging floors, cracks running from the wall to the ceiling, or horizontal cracks in your foundation—it's best to have a professional inspect your floor to determine the root cause.

Yes, you can build over a stump if the roots are no longer alive. Living roots will continue to grow and may damage your new construction over time. Similarly, you should also remove rotting stumps because they may continue to attract pests and even cause new structures (especially those made from wood) to decompose as well.

Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.

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.

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