Get matched with top structural engineers in Cotati, CA

Q: What are the disadvantages of a cathedral ceiling?

• <div><p>Cathedral ceilings make a statement in your home, but at the cost of your attic space. Normal attics are wide open, which allows warm air to move around and exit your home. Because of this, cathedral ceilings make your home less energy efficient and put your ceiling at risk of venting issues if you&rsquo;re not careful. They also reduce your attic storage space, potentially cause an echo, and even make it harder to change a light bulb. </p></div>

Q: Can you put a doorway in a structural wall?

• <div><p>Yes, you can put a doorway in a structural wall; in fact, most exterior doors are set into structural walls. The project is a little more challenging than installing a door in a non-load-bearing wall because you need a structural engineer to assess the wall and make sure it&rsquo;s safe to create a wall opening. Your engineer&rsquo;s report will include instructions for your contractor on how and where to install additional supports, like steel headers above the door, to distribute the weight above to the wall on either side of the door.</p></div>

Q: What is the 10 10 rule in construction?

• <div><p>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&rsquo;t a hard-and-fast rule, but it is a ballpark figure to begin with when estimating your expenses on a job.</p></div>

Q: Do services include structural reinforcement?

• <div><p>Yes, professionals reinforce the foundation with additional supports or piers to prevent future sinking.</p></div>

Q: Do structural engineers do free quotes?

• <div><p>Most structural engineers offer free quotes, regardless of the size of the job. For simple inspections when buying or selling a home, engineers typically charge a flat fee that may be based solely on your home&rsquo;s foundation type and square footage. For larger projects, like new construction and major home renovations, an engineer will either perform an analysis of your project and site and provide you with a formal estimate, or they will do a more in-depth assessment and in-person site inspection before coming up with a per-hour or per-project cost estimate. In most cases, the estimate is free.</p></div>
