"Geico Builders and Brian did a fantastic job. He helped us in demolishing a front deck and replacing it with concrete, relocating a tree from the backyard to the front area and assisting with other odds and ends around the house like fixing the lock on the front window, fixing the latch on the entry fence, etc. Geico Builders were professional, courteous, efficient and did great work. Highly recommended."

"Groundwork’s did a great job on our house. Luis G was an amazing Forman with Ken H and Mark P all waterproofed under our house. They worked quickly, efficiently and thoroughly left all areas in tact and clean. Luis communicated very clearly about the all aspects of the job until it was completed."

"Overall, I was pleased with the result. The scheduling of the initial estimate and the start of the work were not smooth. The estimator missed the original appointment. Later, once I sent my deposit for the work in, I there was no communication for quite some time from anyone. I had to call and ask when they would be coming to do the work. I also had to persuade them to install the Thermal Dry tile, which they initially did not want to do, as they had no experience with it. They did not order enough of the tile, which delayed the job. However, the installers, once they got started, in particular Daniel, were very professional and punctual. My house was recently on a neighborhood Home Tour and half a dozen people wanted to know about the Thermal Dry tiles for possible installation in their own basements. I wouldn't be surprised if that product starts being in high demand."

"Mike showed up asap, scoped the job requirements, gave a written estimate that was accepted by insurance company, had team out next morning to roll up rug in bedroom, break through concrete floor, locate actual leak (~6" laterally from where professional had estimated it to be) and about 18" beneath floor surface, repaired pipe, pressurized system to check it, however repaired pipe leaked (crimping a fitting onto corroded pipe didn't work), then properly cleaned, sweated new piece of pipe into place, repressurized system, inspected new work to verify success, filled hole with sand, covered and leveled that with freshly mixed concrete. All was completed in 1 day. Kudos. Thanks, Mike! Your timely response was greatly appreciated! Mike's bid was higher than that of the leak detection company; however, Mike's company was far more responsive to our need for hot water and was there the next day. The lower bid came from a company that wanted us to wait 21 days(!) for them to repair it. Since we had an understanding insurance company, they were willing to pay the higher cost for our comfort and convenience. That's right! You read it correctly. An insurance company that looked beyond their bottom line to put our needs first."

"I called to set the appointment.  they gave me a three hour time window.  the gentlemen showed up towards the beginning of the time frame.  they were very courteous.  They explained what they were going to do, how the equipment worked, and about how long it would take.  They cleaned my vents in a reasonable time.  They also vacuumed up all the spider webs around my furnace while they were down there (I have a stone basement so it is a never ending battle).  The next time I need my vents cleaned I will absolutely call them.   I have recommended them to everyone I know."

FAQs for basement waterproofing projects in Concord, CA

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
