"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!!"

"Sure Safe came out as promised, thoroughly inspected the foundation via the crawlspace and gave me a detailed report and estimate within a few days. Art was very generous with his time and honesty in speaking with me after the report was delivered."

"Thank you Built Strong Construction for repairing our foundation!!! We’ve had sagging floors for years now but just recently got more cracks and doors weren’t closing and just swinging open. We hired Built Strong to fix our doors and they ended up fixing our entire foundation for a low cost. We now have our floors leveled and strong, besides the doors finally closing smoothly. We got more than we expected and so happy, thank you."

"We had a slow start at first but that was not because of Ryan's service, we originally contacted him in February and was on his schedule for February 24th, however the current Job he was working took longer as the job apparently had grown into a longer job.  So we scheduled to February 27th, and then the rain started we had several much needed storms coming in and it was very important that the decks were totally dry before coating and it had to be dry for at least 48 hours after the coating.  Our next schedule was on April 8th due to March being off and on rain. <br /> When Ryan arrived at 10:00 in the morning he brought the material the his crew would need to complete the job, his crew was a little late but once the started the job they did a very efficient job and cleaned up after they were done they were very pleasant and professional. All in all we are very happy with Ryan and his crew. <br />"

"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."

"We used them to paint the interior of the house a few years ago, and they did an excellent job. When the exterior needed painting, I called them again without hesitation. Edwin was on time for the appointment. I explained what was needed, and showed him the areas of stucco that was leaking in the rain. He suggested sealing the cracks with silicone, and applying Thompsons Water Seal to the area as well. It took 4 days to paint the house and doors. The crew of 3 arrived every morning between 7:30 - 8:00, and left in the evenings after 5:00. They started by powerwashing the house, and worked on the high areas first. The yard was kept very clean, but a side gate was left open most evenings. Not a big deal, but I am glad I checked before letting the dogs out! Edwin suggested changing the color of the side door to the garage to the color of the home trim and rain gutters. I was hesitant, but went with his professional opinion. The color change on the door looks great! The home and trim is the same color as before (a light peach with brown trim). No problems with the work at all, and it has rained several times and no leaks!! I would definitely continue to use and recommend Juon Painting"

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.
