"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!!"

"One of three quotes we got on our home for a big project involving cracked beams/joists and piers. Suresafe gave us a quick inspection followed by a quote- with the wrong math. When emailed questions pertaining to the 15k+ project few were answered- and when I called their tone was that I clearly didn't know much about foundation repair. I value when someone takes time to share expertise in their area of work so I am comfortable paying that amount of money- I did not feel that in this interaction. Opted to not use their services."

"I had Built Strong level my home and quite impressed. Their crews are extremely knowledgeable and experts at what they do. They took photos throughout the project, even custom fit/ repaired my foundation in specific difficult areas and my home now leveled like new. Impressed with Built Strong."

"Overall the job took the better part of a week and from our perspective was a success.  Ryan worked with us in selecting <br /> the right color for the stain.  He carefully removed and replaced the numerous potted plants we had on the deck and left <br /> the work area in a clean condition.  The patio and balcony look great and our only regret is that we didn't do it earlier."

"After applying the stop leak product (Henry's 208R) to the areas pointed out to me and in his report, my roof has stopped leaking. I have also touched up a number of other areas that he pointed out had potential to begin leaking."

"They were excellent and I would definitely recommend the service provider to anyone else. They showed up on time, they were very dedicated to their work and basically I think the painting was included in cost of the service. One thing that was very impressive about this company was that the paint they actually had to purchase was a lot more than what they had anticipated because I wanted to paint the room yellow and the yellow looked like they painted it for which I think they spent like double the price on the paint than they originally expected. They did not charge me any extra because it wasn't mentioned in the quote initially."

"The estimate was very thorough and every question I asked I was provided an in depth explanation. Their bid came in higher then others, but I really appreciated them taking the time to explain why they recommended certain work vs. the other solutions. They also back up their work with a 25 yr warranty. Throughout the whole process EJ was very responsive over email and anything that came up a representative from the office would come to site to check on the work. The men doing the work were always on site before starting time and worked hard. Carlos was very easy to talk to and made it a comfortable situation considering it was three + weeks with them directly underneath your feet, our house on stilts and not much space to work with. They were all very nice guys. All the work passed inspection. Towards the end I think the pressure to finish was on and there were some hiccups in the quality of the finished project, but EJ took good care of us and made sure everything was to our satisfaction in the end. I am very happy with the work and would highly recommend them to anyone who needs to get foundation work done."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Los Angeles, CA

The most affordable way to waterproof your basement is with interior methods like waterproof paint, costing between $1 and $8 per square foot, or silicate concrete sealers priced at $4 to $6 per square foot. However, these solutions are only suitable for certain issues. If your basement moisture is due to more serious problems like a cracked foundation, you'll need more extensive (and costly) repairs.

Absolutely! Waterproofing your basement is a smart investment that can increase your home's value. By keeping your basement dry and free of moisture problems, you protect your home's structural integrity and make it more appealing to potential buyers. Plus, taking proactive measures now can prevent costly water damage repairs down the line.

The time required to waterproof a basement depends on the selected method. Some approaches to interior waterproofing, like paint or sealant, can be completed within a day. Installing new drains or weeping tiles will need at least two to three days of labor. Any forms of exterior waterproofing that require you to excavate land will require an additional three days of work to prepare the ground.

Yes, basement waterproofing can significantly increase your home's value. A dry, leak-free basement is a strong selling point for potential buyers, enhancing your property's desirability and market price. Investing in professional waterproofing not only protects your home's structural integrity but also ensures a healthier living environment by preventing mold and mildew growth.

Waterproofing both the interior and exterior of your basement offers the best protection against moisture. Exterior waterproofing stops water from penetrating your foundation, while interior methods manage any moisture that does enter. If you must choose one, exterior waterproofing is generally more effective, as it prevents water from reaching your home's interior in the first place.
