"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."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Sun Valley, 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.
