"When I first called someone answered the phone. I got an idea on cost and said I had others to check on. I placed calls to 7 other plumbers and none of them got back to me. I called Sgt. Smith back and asked if they could do the job. They said yes and came the same afternoon. I was VERY IMPRESSED with the owner who came to do the job. He was very professional and let me know every step of the project he was doing to unclog the drain problem I had. I can't say enough of how well I was treated and his first rate customer service. I would highly recommend Sgt. Smith drain cleaning service to one and all."

"I had a great experience with this plumber! He arrived right on time and was very professional and friendly from the start. I had a leak in the plumbing in the wall between the bathroom and the bedroom and he took the time to explain exactly was going on. He even went under the house (in the cold and dark) to inspect the issue further and took pictures so I could clearly see the problem myself. He explained the repair in a way that was easy to understand and fixed the leak quickly ad professionally. I really appreciated his honestly, communication and the quality of his work. Everything is working perfectly now! I definitely would recommend him and would happily call and refer him if I ever need a plumber's help!!"

Toilets FAQs, answered by experts

If you notice water leaking down the side of the bowl or tank and you don’t notice any cracks in the porcelain, the odds are that it’s condensation. If you notice water around the base of the toilet, this points to a leak. Check for loose bolts. A sewage odor may also indicate a broken toilet flange.

Even though they’re modern-looking, easier to clean, can be hung at any height, and help save space compared to traditional toilets, wall-hung toilets have some downsides. They’re more expensive than standard toilets, sometimes by a few hundred dollars. They’re also difficult to install and may require major plumbing work to reroute the drain if the previous toilet was a floor-mount model.

This tight fit can make repairs more difficult. You’ll also have to consider where you can hang them and weight limit restrictions, so they may not be the best fit for every home.

The most common reasons a toilet won’t stop running are a faulty flapper or fill valve, improper fill height, or incorrect chain length. Luckily, all these issues are relatively easy to fix with parts you can find at a local hardware store. You can also call a plumber or toilet repair professional to solve the problem.

If you notice water coming out of the bottom of your tank or the flush handle, you obviously have a leaking tank. Water on the side of the tank can indicate cracks. Other signs include the toilet running and flushing without anyone touching the handle, needing to jiggle the handle to make the water stop after flushing, or needing to hold the handle down to empty the water tank.

Adding another bathroom isn’t the most complicated project you can undertake, but it’s in the top 5%. Anything involving plumbing and electrical work should be handed off to a pro, and adding a half bath involves both. A contractor may charge $70 to $120 an hour for labor, but chances are they can work much faster and more accurately than a DIYer.
