"Had a flooding basement and Collins sent out Blake and Adam right away and they did a really great job getting the drains unclogged and running a camera through and taking the time to show me the condition of the whole drain pipe. Really professional and lowest price of all the bids I received, definitely recommend!"

"We highly recommend US Waterproofing. Unfortunately, after repeated issues (we’ve had water getting through a basement door, water backing up from drain/sewer pipe, foundation cracks – all which were addressed) we now have had issues with hydrostatic water pressure delivering a great deal of water to our finished basement. Only one solution – drain tiles and sump pump installation. US Waterproofing was outstanding, every step of the way. They communicated clearly what was needed, and much to our surprise, what was not. They did not ever try to sell us anything that was not needed – only what was – installation of drain tile, window well drains, sump pump, and all work related. All of the crews involved were outstanding – in particular, the crews installing the drain tile and sump pump. The supervisor clearly and concisely explained every step – and when issues arose, they were dealt with promptly. The teams removing drywall and reinstalling also did very good work, and were very responsive. Everything was done correctly, and on schedule The work is now complete – and the basement is back to normal. I commend USW on all facets – they explained everything, did not try to oversell anything, and were responsive to issues as they arose. All the way around – sales, customer support, install teams – outstanding. If you have an issue with water in your home, please consider US Waterproofing."

"Did an excellent job installing new water heater and repairing several issues that developed once we turned water on. Water system had been drained for winter shutdown. Without any hesitation Brad quickly went from room to room fixing all leaks. Was very impressed with customer service."

"Roberto did a drain in our back yard and did a great job. I asked him to quote our patio which needed alot of work. The quote was competitive so we hired him for that as well. Him and his crew were excellent and they do a phenomenal job. Highly recommend."

French Drains FAQs, answered by experts

You should hire a sewer service professional to unclog a main sewer line with tree roots. Tree roots can grow into the main sewer line, and this problem requires a specialized hydro jet, or rooter, that is powerful enough to clear the roots. The tree can also damage the main sewer line, and a professional will need to make repairs or replace the damaged sections. Sewer line replacement costs about $60 to $250 per linear foot.

Most commercial liquid drain cleaners work in 15 to 30 minutes. Consult the label on the bottle for additional instructions or time suggestions to prevent damage to your drainpipes. Alternative solutions such as baking soda, salt, white vinegar, and/or boiling water can take longer since they are less harsh than liquid drain cleaners.

While some chemical drain cleaners with hydrochloric acid can dissolve hair, this method is not recommended as it can also destroy your plumbing pipes. A common DIY alternative is using baking soda and vinegar, which can help break down the clog but will not actually dissolve the hair. The best and safest method for clearing a hair clog is to remove it manually. You can use a drain snake, a straightened wire hanger with pliers to fish out the clog, or have a plumber use a professional auger for more severe blockages.

The best drain cleaners are biodegradable ones or a mixture of baking soda and vinegar. Strong, caustic chemicals may seem appealing with promises of unclogging your drain quickly, but liquid drain cleaners can cause damage to your pipes over time. Consider making your own drain cleaner with baking soda and vinegar.

For disposal clogs with standing water, use a sink plunger and place it over the garbage disposal drain. Push the sink plunger up and down the drain about six to eight times before lifting. If the sink drains, the clogged food particles are dislodged from the drain. If there’s still standing water, repeat the steps until the standing water clears out.
