"I received 5 quotes for the work I needed done.  Uneven Floor Solutions won the bid over larger companies because of their reviews, owner and employees which were exceptional!  Had a partial french drain and sump pump installed inside of basement which was completed in a day.  Waited until we had plenty of rain before writing this review.  Masle and his employees did a perfect job; and I am a hard person to please.  They were efficient, thorough, professional and experts in their field.  Never have I seen such diligence and pride in one's work.  I can't say enough about Uneven Floor Solutions and highly recommend them.  Hope you are as fortunate as I was to finding  them."

"Damion, David, and Roderick were a great team. They arrived on time and completed the project in a timely manner. This was a crawl space encapsulation under a 30 year old house that had no attention to this space at all. This is the kind of maintenance project that is very worthwhile and they did it right. It was not in bad shape but they made it perfect!"

"Greg and his employees did an amazing job!! From start to finish it took three days and if you had saw our crawlspace I didn't think anything could be done. Our crawlspace went froma dark, dank, moldy, snake infested, armadillo incubator to a space that is as clean and seems as hygienic as a hospital operating room. I would not go anywhere near our crawlspace before and now have no issues crawling anywhere I want or need to go under the house. they even went beyond by adding some lighting and fixing our airhandler so it didn't drain under the house anymore. I highly recommend Greg and his team at Crawlspace Doctor to turn your space into what it was meant to be."

"Called, they were on the job within a few hours, the guy they sent busted his BUTT and got the tree down, sectioned Into moveable sizes, even helped me to load three big pieces that wouldn’t roll into his truck to haul off, and he cut the stump down good and low. They negotiated on the minimum price, and couldn’t have been nicer or more professional. Call Samantha, Blitz will take care of you the right way."

French Drains FAQs, answered by experts

If you've discovered a rather frightening buildup of brown and black gunk below your shower cover, you're not alone. The smelly sludge is often a collection of mildew and biofilm. Biofilm comes from the breakdown of soap scum, hair, skin cells, and bacteria that collects during shower time. It's quite common in a humid space and relatively easy to clean with a gentle DIY cleaning solution such as baking soda and vinegar.

The cost varies from $150 to $600, depending on the severity of the clog, pipe access, and required equipment.

French drains may fail when they become clogged with soil granules that slip through the pores of the landscaping fabric and through the holes in the pipe. 

Over time, this debris can build up inside the pipe and prevent water flow. To prevent this failure from happening, regularly flush out your French drain and keep debris away from the inlet grate.

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.

Common drain issues include slow-running drains, whether in a sink or shower, clogged drains, a bad smell, and water backing up into a sink, shower, or bathtub. Causes range from hair, grease, roots, or toilet paper clogging the drainpipes to flooding outside the home, which prevents sewer lines from draining properly.
