"Andrew and his Crew from Roseburg were wonderful. They were able to get into our crawl space and did an amazing job clearing it out, installing drainage, a layer of plastic and sump pump. They left the area so much cleaner than it was when they arrived and they explained everything to us clearly so we would know what to do. We recommend them highly and it was a pleasure to meet them."

French Drains FAQs, answered by experts

Once you’ve poured the baking soda and vinegar into a drain, you should wait about 10 minutes for the mixture to break down the clog. If you try the baking soda and vinegar method and it doesn't work, you can do it again or try the baking soda and salt trick.

Regardless of the drain cleaner type you choose to use, they all work through chemical reactions that create heat. Thanks to the heat, the clogged hair begins to dissolve until it is able to be flushed away. To avoid clogs in your drain due to hair, use hair catchers and empty them out after every shower.

Yes, drains are one common entry point for water bugs. However, water bugs may enter your home through various locations including doors, windows, pipes, and vents. Water bugs are drawn to the dark and moist atmosphere drains provide, and can easily find their way into your home through sewer drain pipes. You can stop water bugs from entering through drains by regularly cleaning your drains and repairing faulty drainage systems.

Flushing the toilet only to realize it’s clogged can cause anxiety. To avoid a clogged toilet, use less toilet paper. If you notice that the toilet is flushing and refilling slower than usual, you can use a plunger to clear clogs in the S-trap. If that doesn’t work, call a plumber to check your system and possibly clear the drain lines.

Vinegar is better for an AC drain line because it’s less corrosive and won’t damage the pipes. It’s also a safer and easier product to use. Bleach should not be used on your AC drain line because it can corrode your pipes and harm the evaporator coil in your air conditioner.
