"I called to set up an estimate on a Friday which was scheduled for the following Monday. I was considering both attic and wall insulation. Mark arrived Monday on time and confirmed with texts as follow ups. He quickly determined that I already had some insulation inside my walls and evaluated my attic space. He said there wasn't much and was likely the original insulation from when the house was built in the 1960s. The estimate came in at just over $1000 which was quite reasonable based upon similar quotes I had read online for similar sized houses as mine. It would also bring the insulation level to the recommended level by PG&E, just above code. When he looked at his team's schedule they had an opening the next day in the morning which worked out quite well for me. The team of 3 arrived on time and the job was completed with an hour to go of the allotted time. I was told that I should easily notice a difference as what was there was not much and the results would seem to be "night and day" compared to what I was used to. True to this claim yesterday (first day of summer 2018) was the first real test of heat with Concord peaking at about 105̊but inside was a good 20̊cooler than outside keeping the inside of my house much more comfortable than previous to my insulation upgrade. I was waiting for such a result before posting this review. I highly recommend All Seasons! Thanks guys!"

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Bethel Island, 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.
