"The service was good, they were able to fix the problem and make my air conditioning run during the summer."
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.

"They initially re-plumbed our entire house years ago so we are still under a service contract with them. They do excellent work. We have had no problems with them. They were very professional. There were only about two of them here at a time and they come do whatever they have to do and then, the construction crew came in after them and did what they had to do. We are very pleased with them. A lot of companies would not work with construction crews that way, but they do."

Basement Waterproofing questions, answered by experts

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.

Preventing future basement flooding often involves installing sump pumps, improving drainage, sealing foundation cracks, and maintaining gutters. Costs vary, but preventive measures can range from a few hundred to several thousand dollars, depending on the solutions chosen. Investing in prevention can save you money on future flooded basement cleanup costs and repairs.

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

Plan on cleaning your crawl space at least once a year, though twice a year is ideal. During the cleaning, remove any debris or dust and check for potential issues like pest infestations or water damage. The sooner you catch these issues, the easier (and cheaper) it will be to fix them.

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.
