"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

Structural Engineering questions, answered by experts

In many areas, advice from a structural engineer or an architect will be required by your building department before you can remove a wall, but even if it’s not necessary, it’s a good idea. Accidentally removing a load-bearing wall—even if a general contractor advises that it’s safe—can cause major structural damage, putting you and your family at risk and potentially costing thousands or tens of thousands of dollars in property damage.

In framing, studs are placed at 16-inch intervals to coincide with the typical spacing of wall materials such as drywall or plywood. This spacing is called "on-center" and is necessary for maintaining structural stability and efficient use of materials. The 16-inch spacing also helps to distribute the weight evenly across the building's structure. For those looking to cut material costs and improve energy efficiency, 24-inch stud spacing can be employed through a method called "advanced framing". This requires careful planning and adherence to local building codes to ensure structural integrity.

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.

The depth of any foundation style depends on your climate and how deep the frost line is, as building code requires that the footers of a foundation—which are built into a monolithic slab—sit at least a foot below the frost line. At the southern tip of Florida, for example, a monolithic slab foundation would only need to sit 12 inches under the soil at the widest parts. On some parts of the Canadian border, the frost line is 100 inches, which would mean a minimum of 112 inches, which is prohibitively deep for a monolithic slab.

While concrete walls do not need to "breathe" in the traditional sense of the word, they do require waterproofing and dehumidifying methods, particularly in basements below the water table. Concrete both contains moisture from its initial installation and can absorb water when exposed. Ensuring proper basement ventilation , installing a vapor barrier, and controlling water exposure are all important tasks.
