We have been in the construction industry for over 10 years. From building ADUs, high-end kitchen remodels, bathroom remodels and home extensions, we have done just about everything under general construction. Our company prioritizes safety, quality and transparency.

"Me and my wife decided recently to get our kitchen remolded. After some time searching for the right guys to do the job we settled on RG Construction. Richard, who is the owner, is a great guy and super informative. He never left any question unanswered or left us uncertain about anything. His crew works quick, and they pay attention to the tiniest detail. They absolutely are worth every dollar and I would recommend RG Construction to any homeowner, and I for sure will be giving them a call back for any work I need done in the future. Me and my wife are absolutely in love with our remodel."

"We hired Groundworks CA (fka Bay Area Underpinning) for what we understood was a full foundation repair. We paid $42K. They only worked on the rear and never informed us that the front wasn’t included. Months later, while selling our home, a third-party engineer found $189K in unaddressed issues at the front. We were blindsided, lost our buyer, and suffered major financial and emotional stress. Groundworks later admitted they hadn’t measured the front. Their rushed “final inspection” months later felt reactive, not professional. When asked for a partial refund, they refused. We feel misled and abandoned. Avoid."

Basement Leak Repair questions, answered by experts

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

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.

The need for permits in drainage improvement projects depends on your location and the extent of the project. Generally, projects involving significant excavation, alterations to existing drainage systems, or those impacting public drainage systems may require permits. Check with your local building department or authorities to determine the specific permit requirements in your area before starting any drainage improvement work to ensure compliance with local regulations.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.
