Foundation inspection, repair, and replacement services for Los Angeles and surrounding cities for more than 20 years. With 800+ 5-star reviews online, we continue to provide affordable foundation inspection, foundation repair, foundation upgrades, foundation replacement, earthquake retrofitting, house bolting for the greater Los Angeles area; including affordable upgrades to your foundation. We pride ourselves in repairing only what your house foundation needs. We offer foundation upgrade services to get your house to full earthquake standards for the Los Angeles area without necessarily having to rebuild your full foundation, saving you thousands in unnecessary repair if at all possible.

"Of all the companies I approached to perform the obligatory inspection in order to assess the scope of work to be done on my foundation (which is extensive), Foundation Works is THE ONLY company that charges a fee. Consumer beware - it does not state this anywhere here on Angie's List nor on Foudation Works' own website. You will only discover this only AFTER speaking to a representative on the phone trying to schedule this inspection. A fee of $215 to inspect a foundation requiring approximately $50K of work had the effect of immediately removing this company from further consideration for the job."

"I worked with Alpha once before, and they assisted with a second project 2 years ago which, now finally completed, I'm able to write a review about. Alpha helped with structural plans for windows in a garden level unit in order to prepare the proposal for city approval. Alpha is a big company and it took them a little while to complete everything; however I can certainly say that the engineer and contact people were knowledgeable and thorough. The plans were approved with their help and now that the unit is permitted for occupancy, the windows are a lovely attribute to the space."

"Victor drilled a drainage hole in my concrete curb with his core drill. The work went well. He paid close attention to placing the drill relative to the inclined asphalt of the street to drill a hole that will let water run downward and out onto the street, without puddling inside the hole. Both he and his assistant were congenial and easy to work with. The cost was very reasonable. I recommend Victor's service highly!"

Foundation, basement or crawlspace waterproofing / encapsulations FAQs

Cleaning your crawl space is a worthwhile investment for several important reasons. A properly maintained crawl space prevents structural damage by eliminating moisture that can deteriorate wood supports and metal components. It also significantly improves your home's indoor air quality by removing allergens like mold spores and pest droppings that can circulate through your living spaces. 

Additionally, a clean crawl space contributes to better energy efficiency by allowing proper insulation installation and reducing humidity levels that force your HVAC system to work harder.

Several warning signs indicate your crawl space needs professional attention. Look for musty odors throughout your home, unexplained increases in allergy symptoms, higher energy bills, visible pest activity, or moisture issues. 

Other indicators include sagging floors, warped wood, visible mold growth, standing water, or damaged insulation. If your crawl space hasn't been inspected in over a year, or if you've recently experienced flooding or severe weather, it's advisable to have professionals assess the space even without obvious symptoms.

Most crawl space cleaning projects take between one and three days to complete, depending on several factors. Simple debris removal in a small, relatively clean space might be finished in a single day. 

More involved projects that include mold remediation, water damage repair, or pest control require two to three days. For large crawl spaces or those with extensive contamination, the timeline might extend to a week, particularly if additional services like encapsulation are included in the project scope.

You can remain in your home during basic crawl space cleaning. However, if the project involves mold remediation or pest extermination with chemical treatments, temporary relocation might be recommended, especially for household members with respiratory conditions or chemical sensitivities. 

Professional cleaning companies use containment procedures to minimize the spread of dust and contaminants into living spaces, but some disruption is inevitable. Discuss your specific situation with your service provider to determine the best approach for your family's needs.
