"5++ stars! My home's exterior was cracking due to a poor job prior and drainage issues. Tom and Adam and the team not only gave me peace of mind moving forward with drainage, put in gutters, and re-did the entire exterior of my home (stained wood and stucco), but made it beyond beautiful!! They were communicative, timely, so easy to work with, and the end product is gorgeous. I would recommend them to anyone who needs a construction project done and can't wait to use them again on my next project!!"

Our company history provides you with four generations of construction experience. It began in the early 1950’s when Guy La Rocque’s grandfather ran a successful steel and concrete company and, up until his un-timely death, Guy’s father owned and operated one of Southern California’s largest fence companies. Guy La Rocque acquired 100% ownership of La Rocque Bros Co. in 1979 and in 1981, changed the name to La Rocque Roofing. In 1984 the family decided to incorporate the company, hence the name change to La Rocque Better Roofs, Inc. Currently the company employs two generations of the La Rocque family with no intentions of stopping there. The reputation that we have built over the years is something we understand. It takes a great deal of effort and a daily dedication to our employees, clients, distributors, and manufacturers. We are constantly upgrading our company and looking toward the future. One of Guy’s philosophies is the only thing constant with our company is change. For him, this company is more than just a job, it is a hobby, a passion, and testimony of what was, what is and what will be. The La Rocque family considers themselves blessed and credits their success to God. Colossians 3:23-24 Visit Us online to request your free estimate: http://larocquebetterroofs.com/request-a-quote

"We've used Guzman Contractors a few times and have had excellent experiences with each service. This job was a small one that only took a day and a half. Carlos installed a 6' x 4' window in our game room and finished it to match the existing interior and exterior molding. it looks perfect. Plus the room gets a ton more light and we have a beautiful view of the forest. As always, he was on time, reasonably priced, clean and quiet, and a pleasure to deal with. We will use him again. Highly recommended!"

"Contractor Home Builders provided my husband and I with excellent and high quality service. When Max from CHB came to our home we had already received estimates from 10 other contractors. For various reasons related to pricing and products those contractors were not able to meet our needs. CHB was able to give us what we wanted in a timely and efficient manner. When CHB’s staff showed up to work the arrived in a timely manner and eager start working. They were all friendly, professional and courteous.

Structural Engineering questions, answered by experts

It’s possible to drill into an LVL beam, but you should always avoid it. LVL beams are major structural components of your home, and drilling into them can weaken them and lead to cracking over time. If you need to drill into an LVL beam, consult a structural engineer. They’ll know the bit size, depth, and directionality that’s safe to use when drilling.

Squeaky floors don’t always mean structural damage. Usually, it’s caused by friction somewhere inside your floor—whether it’s a loose floorboard or a gap between the subfloor and joists. If there is structural damage, you’ll notice other signs like soft or sagging floors, cracks that go from the wall to the ceiling, and horizontal cracks on your foundation.

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. 

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

Most load-bearing walls are exterior, though they can also be interior.
