We used terrafirma to both waterproof the entire basement AND lift the foundation. 10/10 would recommend. extremely communicative, very knowledgeable, and even brought a crew in from Oregon to help us stay on schedule. Oscar and jorge got the job done extremely quickly and Seth was fantastic as my project manager."

Blew installation above the garage, cleaned out the crawl space and put new installation there and basement. Found a water leak from my toilet,Thank goodness. Covered everything in the basement and swept and cleaned up after. I would recommend them!"

"RainPros sealed and installed drainage to stop water leakage through our basement wall. They were very competent and professional, and handled the job with a minimum of disruption to us. They kept us informed as the project progressed and at the end restored the site to its original condition. I highly recommend them."

The price was reasonable compared to comps, and the job was finished when they said it would be. We've had some torrential rains since and not a drop has gotten into my basement!"

Basement Waterproofing questions, answered by experts

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

In some circumstances, foundation refacing or repair may be a better option for your home than sealing a foundation. It’s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it’s a good idea to get a professional opinion so you can avoid bigger problems down the road. 

A crawl space encapsulation isn’t always necessary, but it’s a wise choice, especially if you live in an area that sees a lot of precipitation. Sealing a crawl space not only reduces damage caused by moisture, mold, and pests, but it also increases your home’s value. It can also save you money by reducing energy bills and avoiding costly repairs for structural or foundation damage.

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.
