"They were very professional, they did a a quick job and they go above and beyond."
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.

"Perfect! No problems or issues that need immediate attention. Pedro, the technician, left me with a couple of "preventive maintenance" items to consider. No high pressure sales. He was professional, efficient and communicated with me what he was doing, what he was finding, and what to consider to maintain a healthy and happy home!"

"US Trench less was referred to me through a friend. I called US Trench less and explained the situation I had in my backyard. US Trench less came out the next day and ran the diagnostic TV scope where we were able to see how bad of shape my pipes were in. US Trench less was able to come out and start working the very next day. The entire job was done in less than 4 days which was amazing considering how quickly they began working. US Trench less was honest, very trustworthy, knowledgeable, and prompt with my situation. I would highly recommend their work!"

Basement Waterproofing questions, answered by experts

Yes, a crawl space can add value to your home. However, there is a higher chance of it adding value if it is an enclosed crawl space, as this reduces issues caused by excess moisture in the home. That being said, a basement does add more value than a crawl space.

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all. 

Access to commercial-grade products and equipment, ensuring thorough coverage and long-lasting protection.

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.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable.
