"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

The P-trap (or S-trap in older homes) under your shower is designed to prevent sewer gas from coming back up, so you shouldn’t normally experience foul odors coming from your shower drain. If you do, the vent stack that introduces air into your plumbing system may be clogged, or you may have a more severe sewer main blockage. In either case, hire a plumber to fix the issue for you.

There are a few ways to unclog a toilet without a plunger. Break up the clog with homemade solutions containing soap, vinegar, and baking soda, or simply let hot water spend some time in the drain. You can also use a two-liter soda bottle filled with water to push pressurized water into the pipe to dislodge the debris (see the steps above).

Yes, pop-up drains commonly get clogged with hair, soap scum, and toothpaste. It is important to know how to properly clean the drain or get professional help to ensure it remains clear and can drain water effectively.

Septic tanks can clog if they aren’t pumped every few years since solid waste accumulates inside of them. Your tank might also clog if you have a habit of flushing anything other than human waste or toilet paper. Items like diapers, baby wipes, paper towels, cat litter, and personal hygiene products should never go down your pipes.

Yes, frozen pipes can cause a toilet to stop working correctly. If the pipes are frozen, water cannot flow, which can lead to two main problems. First, the supply line to the toilet tank may be frozen, which prevents the tank from refilling with water after you flush. Second, the drain pipe itself can freeze, blocking water from flushing away. As a temporary solution for a non-refilling tank, you can manually add water, but this is not a long-term fix. To clear a frozen drain pipe, you can try pouring warm water into the toilet bowl or tank and then flushing, as the warm water may help thaw the ice blockage. Ultimately, the best course of action is to unfreeze the affected pipes to restore your toilet to full functionality.
