"I highly recommend Groundworks for foundation concerns. They were very prompt with returning my call and providing a free inspection. I had concerns for my 103 year old home, especially a section of the foundation. Their Inspector, Bob Bloom, arrived on time, was professional and experienced, took time to answer all my questions (thank you for not rushing), and provided me with useful feedback on my foundation and options for repair. Bob gave an honest assessment with no sales pressure. Although I decided to defer foundation work at this time, I will definitely use them in the future."

Basement Leak Repair questions, answered by experts

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.

Although waterproofing your basement may not directly increase the value of your home, it will protect the value you already have by preventing water damage. A basement without any signs of water will be more appealing to prospective home buyers. A leaky basement is a major red flag during a home inspection, and it will likely reduce the amount that buyers are willing to pay.

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.

Yes, many contractors offer warranties for their work. Confirm terms before starting the project.

Typically, a French drain can last 30 to 40 years if it is maintained properly. The life span of a French drain depends on factors such as the quality of installation and the types of materials used. However, climate and natural disasters can affect the life span of a French drain. Regular maintenance and inspections can help prolong the drain's life span.
