"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."

"We chose CrawlSpace Medic based on professionalism, reliability, reasonable cost estimate, and previous reviews on Angie’s List. Each day the crew showed up on time, worked hard all day, and cleaned up at end of each day; were respectful of property, and very professional, and pleasant to work with. They kept us informed of progress, and what was being done each day. During removal of old piping, they found additional damage behind the pipes that was not visible/identified during initial inspection- were very reasonable with determining the additional cost. They replaced damaged sills, old rotted floor joists, installed permanent support girders with masonry piers, installed a 10ml plastic vapor barrier, and installed multiple foundation vents. We are very satisfied with the results. Our floors are no longer bouncy, and floors feel very sturdy- was a dramatic difference after work completed. The 10 ml plastic Vapor barrier also has prevented that old damp smell inside the house after heavy rains. Was a good experience, and reasonable cost-(initial estimate $10,400, additional work required and we added foundation vent installation was $3800); would hire again."

"I found them to be very friendly and very meticulous. If they came up with anything else that had to be done, they stood by their quoted price. They took their time and did not rush just to get the job done on time, rather, they took enough time to make sure that the job was done correctly. They started the job on April 15th and it took them like two weeks to finish the job."

French Drains FAQs, answered by experts

Air gaps get clogged by a few different means. Over time, food and grime can collect in the air gap, leading to a blockage. Mineral deposits from hard water are a common problem. Mineral buildup creates a film in the air gap and tubing, which can cause flow issues, as well as attract debris. Homeowners with hard water may want to remove mineral deposits regularly to keep the air gap clean and clear.

No. You should dispose of all oil-based finishing products through a local hazardous waste program. Not only can oil-based finishes be hazardous for the environment if disposed of in the sink, but they can cause clogs in your pipes and stop up your drains. Most municipal garbage or waste disposal companies have a specific location or pick-up schedule for hazardous materials, so that’s your best bet to get rid of excess finishing products.

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

Professionals use snakes, hydrojetting, or chemical cleaners to clear blockages effectively without damaging pipes.

If you're dealing with a clogged sink drain, you may be able to avoid removing the drain by using a plunger to dislodge the clog. While we associate plungers with toilets, they can do the same job with your sink drain. Be gentle, though, as forceful movements can push clogs further into your plumbing system and make them more difficult to remove. Additionally, make sure you’re using a sink plunger—with a flat bottom—and not a toilet plunger—which has a smaller bottom protruding from the larger flat piece.
