"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!!"

"I recently engaged Nick Engineering for a kitchen remodeling, and I must say, their structural engineering work was exceptional. Their design not only gave our house a stunning makeover but also made sure it is built to last. The teams professionalism, responsiveness, and commitment to meeting our expectations made the entire project a breeze. I highly recommend Sam and his team for anyone in need of outstanding structural engineering services for their home renovation projects"

"Working with Jonathan has been a dream. This is the first time I've ever needed and architect and engineering for a home project, and wasn't sure what to expect, but Jonathan was great. He was incredibly patient with the adjustments and revisions that came with the process and pointed out some ideas that I never would have thought of on my own. As a bonus, the plans sailed through the city plan check, getting approved the very next day with no comments. I strongly recommend DesignX."

The costs depend on the type of wood, labor, roofing material, permits, and whether additional storage or enclosed walls are included.

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.

Yes, unresolved damage can decrease property integrity and market value.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

No, it’s not legal for unlicensed individuals to conduct structural calculations for buildings or building repairs. Not only do licensing requirements prevent DIYers from tackling this project, but mistakes can also be extremely dangerous and put your property and anyone inside or near it at risk of severe injury or even death.
