"Ambassador Plumbing was my first choice and the only one of three companies to respond to my request for a quote. Paul came within a couple of weeks and did a fine job of replacing my Mansfield toilet with their recommended Kohler one that met my specifications. I'm very pleased with not just the toilet but the work too. (Note: Ambassador does not honor the Angi 5% coupon displayed on their site.)"

"It did not go as expected. Although the staff is very friendly, professional, and punctual, the actual job did not go well. My toilet was leaking onto the subfloor, so within 15 minutes the plumber determined I needed a new pipe and he would not be able to reinstall my toilet until I fix the subfloor. I fixed the subfloor and called the plumbers back two days later. The office staff that took my call was wonderful and accommodating, and got a plumber out right away to reinstall my toilet. Here’s where the problem is: the first plumber who took the toilet out laid it on its back causing all of the seals in the tank to break. The first plumber also replaced my shut off valve, but placed it about an inch further out of the wall then it previously was. So when the second plumber came to reinstall my toilet, not only could the toilet not be put back up against the wall, but the tank was loose and leaking now and all the seals in the tank had to be replaced. In the end, I paid $700 for this project, which shouldn’t have been more than $350 in my opinion. And since the toilet sticks out so far from the wall the tank is still leaking as it must have been jostled in use. And the base of the toilet no longer lines up with the hole that was cut in the linoleum. It just looks awful and to be honest, I should’ve just had them replace the pipe and left it at that, but the first plumber left the sewer pipe sticking 8 inches up out of the floor and I wasn’t sure how far down to cut it to reinstall the toilet. It was just a mess."

"Could not have been better. Ran into a scheduling issue with another plumber. Called Kirkwood Plumbing on Monday, they were able to schedule us for the next day. Gave them the info from the original plumber's proposal and they agreed to match the cost and work. Plumber was running late due to very heavy traffic. Called 45 minutes before the scheduled appointment to let us know he might be a little late. Arrived only 10 to 15 minutes late, which was fine with us since he had called. Got right to work and finished within a few hours."

"This is a good company to deal with. James, the owner, was out within one hour to diagnose our problem. The next morning the technicians, Brian and Josh were out to take care of our drain issues. Brian made a point of showing me the camera footage of the main drain. The did a great job on the main and two other drains. They also cleaned up very well when they were done. Brian also noticed an issue with our bathtub stopper and fixed it without an extra charge. The pricing was transparent. They have a nice email notice system and called when they were on the way. The three men I worked with were all very professional and easy to deal with. I would not hesitate to use them again. Phil Lykens"

Toilets FAQs, answered by experts

Sometimes, your insurance policy may cover leaking toilet repair. However, home insurance policies typically do not cover any plumbing problems. They do cover water damage caused by a busted pipe or a major leak. Some insurance companies also have riders that expand your initial coverage to include plumbing items. Talk to your agent for more information.

If you decide to replace the toilet flapper yourself, the only cost will be buying the new flapper for around $5 to $17. You can also hire a plumber or handyperson to take on the job instead, in which case you’ll pay an hourly rate for labor plus the cost of parts. Handypersons charge $50 to $150 per hour, while plumbers cost $45 to $200 per hour. This repair might take less than an hour for your pro, but note that many providers have a minimum rate for a house call. 

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.

Yes, pressure-assist toilets leak, but less often than regular toilets. You might experience leaks from your toilet due to worn-out parts, water pressure in your plumbing that’s too high or low, poor installation, or cracks in your tank. These toilets are harder to fix on your own than gravity-fed ones, so it’s best to call a plumber if you can’t figure out what’s wrong, 

Generally, toilet leaking is not an emergency unless the leakage is severe. However, any leakage at the bottom should be addressed as soon as possible because it could lead to water damage to the floors, under the tiles, or into the walls. Leaks at the bottom can also lead to mold growth if unaddressed.
