"Solomon and the guys at Melo Gardens were AMAZING throughout my full front yard renovation!! I replaced my boring, water-guzzling front yard with new modern, eco-friendly landscaping (part of the Long Beach lawn-to-garden program). I couldn't be happier with my finished project! Melo gardens took care of tree trimming, poured a fresh concrete pathway, installed new irrigation, and found some really awesome plants at a reasonable price. Solomon was super attentive to my needs (and trust me, I can be needy lol). He was happy to make adjustments during the installation and also made some really great recommendations. You can tell he definitely knows what he's talking about. All my neighbors have been asking about my contractor I'm happily telling everyone about my great experience!"

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.
