"They responded very quickly and got the Job done right. Very happy with all aspects of the service provided. Thank you!"
Our team at Bonney helped restore flow at this Sacramento home by performing a sewer spot repair on the main line for our customer. This involved locating the problem area, digging the trench, snaking the line to clear the drain, repairing a section of the sewer pipe, and then backfilling the space to restore back to the original landscape.

"Matt did an excellent work and I am very happy! It’s been at least two weeks and no issue from my water heater - no leaks. He was very responsive and he cleaned his work. It is not easy to find someone who can do both in replacing the damaged walls and installing the water heater. I hesitated at first how much he was charging for it was very affordable. It wasn’t a scam and he did an excellent work."

"They were okay. I had an upstairs bathtub and it was leaking a lot and they fixed it. They put a steel mesh around the tub so that the rodents couldn't get to it. He went above and beyond. I am satisfied with his work. He is very communicative, explains things, tells you what he did and what he found."

Basement Waterproofing questions, answered by experts

No, everything doesn’t get wet if the bathroom is well-designed and the fixtures are properly installed. It’s important that the floor of a wet room drains correctly, and proper waterproofing and slip-resistant flooring are used to avoid creating slipping hazards. Since the shower isn’t housed in an enclosed space, you’ll need to make sure the towel rack and toilet paper holder are placed in areas where they won’t get wet.

If not properly maintained, an underground downspout may damage your home's foundation. A clogged downspout can back up, causing water to pool around the base of your home and seep into the foundation. Regular inspections and maintenance keep your downspout in good working order, preventing damage and protecting your home.

If foundation problems are not fixed, they will likely worsen over time, leading to more complex and expensive repairs. Neglecting a damaged foundation can cause a range of issues, including:

  • Structural Damage: Minor problems like small cracks can escalate into major structural issues. This can damage the house above the foundation and, in severe cases, lead to foundation walls caving in or a total collapse.

  • Water Damage and Pests: Moisture and water intrusion can cause flooding, mold growth, and pest infestations.

  • Health and Safety Risks: Mold can lead to poor indoor air quality and other health risks, while structural instability poses a significant safety hazard.

  • Reduced Home Efficiency: A compromised foundation can negatively impact your home's energy efficiency.

To avoid these escalating problems and costs, it's best to hire a foundation repair company to address any issues as soon as you become aware of them. The earlier problems are discovered and fixed, the lower the repair cost will likely be.

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

French drains and yard grading systems are two highly effective ways to fix standing water around the foundation. Since the French drain uses a perforated pipe covered by gravel, you won’t have to worry about water taking the soil away from your foundation. Meanwhile, yard grading levels out the ground to prevent water from gathering around your foundation.
