"Gil did an amazing job of figuring out exactly what I needed, and he hired an amazing crew to get it done. This is by far the best home renovation experience I've ever had. Gil and Oliver both were very thorough in figuring out what needed to be done, and every step of the way if there was ever any ambiguity, they asked questions and came up with great solutions for everything that came up. I have never before had such a good experience with a home renovation, and I wish all contractors were as good as them. My project was fairly involved, with a complete renovation of my kitchen, dining room, and laundry room, and yet the whole process took under a month to get done, and it was done right the first time. I wholeheartedly recommend Your Home Builders. No complaints at all."

Basement Leak Repair questions, answered by experts

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.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

The cost of installing landscape drainage with the help of a professional can vary widely depending on factors like the scope of the project, your location, and the specific services needed. Smaller tasks, such as installing a French drain, may range from $10 to $50 per linear foot, while more extensive projects like installing a catch basin can cost several thousand dollars to tens of thousands. Obtaining multiple quotes from qualified professionals is recommended to get a precise estimate for your specific drainage issue.

Trench drains have a bit of a reputation as being difficult to clean, so if there’s a massive rainstorm that leads to a lot of debris and gunk getting stuck in the drain, you’ll spend extra time cleaning it out. Plus, you definitely need to regularly clean the drain, heavy rainstorms or not, to keep it in good condition, adding an extra step to your cleaning to-do list.

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.
