Very professional!!"

"I met Gert when we hired him to replace our Tankless water heater. I was so impressed with is knowledge and concern to make sure the installation was neat and clean. The piping is literally a work of art. We met with Gert and Sergio to discuss the next phase. They removed all the galvanized pipe and installed 3/4" copper with a true hot water recirculating line for Tankless recirculating pump. Before they started work, they came in and placed protective covers over the hardwood floors. Sergio and his team replaced all the cast iron drains with ABS. They even opened walls where needed to get to the old galvanized drains to the sinks. They pulled up toilets and replaced the old flanges with new ones. All that's left is the sewer line from the house to the street. We will be calling Gert and Sergio when reach that point. Gert, Sergio and the whole crew have something you do not see that often anymore. That's integrity and concern for their customer. Also very conscientious of keeping our home clean."

"He was wonderful! We had several issues with our toilet and system being backed up because employees/clients flushed items down the toilet over several months. Each time we had an issue, Jess came out promptly and fixed everything. He is always friendly and helpful. When a large section of our pipes needed to be replaced, he fixed it, did an excellent job AND even came out over the over a holiday weekend! We will continue to use Jess whenever we have plumbing issues!"

"My sewer line was backed up and I had sewage coming up through my bathtub and sinks. Ron and Cesar came out right away and were able to clear the line! They showed me what they saw with their camera line and they noticed a bunch of wet wipes stuck in the sewer line. Looks like I’ll need to talk to my wife about that… Thank you again Ron and Cesar!"

"Jose and his team were very flexible in allowing us to continue to live in our home while fixing our water line. In the process he showed us how rusted out our line was from our water meter to our house and regardless of what the progress was, we always had water for the kitchen and bathroom for the 3 days required to replace ALL of the galvanized piping with new copper. He also resolved an un-level toilet issue in both bathrooms. We never knew it was not supported properly until he showed us; he quickly leveled the foundation under the toilet which we appreciated. Jose always listened to our concerns, and answered every question we had regarding the water piping replacement. Picture shows the leaking and the final copper replacement."

Toilets questions, answered by experts

The average cost to replace a toilet seal ring is around $50 to $200 if you hire a pro to do the job. If you do it yourself, you’ll only need to pay for the supplies. Wax rings alone cost anywhere from $5 to $25 at hardware stores and can save you a lot of money compared to having a professional installation. At the same time, a licensed plumber knows how to properly install your new wax ring to prevent premature issues down the line.

Sealant doesn’t need to be applied to the bolts, but it can be a good way to stop an active leak in the moment. However, don’t rely on it as a cure-all; instead, make sure to fix the problem at the source by changing or tightening the bolts. 

If you do use sealant, make sure to spread it thickly and evenly across the bolts and the tank's porcelain.

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. 

For best results, you should remove the toilet in a bathroom before removing tile or installing new tile. If you don’t remove the toilet, it will be harder to fully waterproof the tile around the toilet, which could increase the risk of mold growth or plumbing leaks. If you have trouble removing the toilet, hire a plumber to help.

Toilet seats have two mounting brackets on the back that accept mounting bolts. The bolts drop through the brackets, through two small holes on the top of your toilet, and then receive nuts to hold them in place on the bottom of the toilet. If you can’t see the bolt heads, you might need to pry up the mounting bracket cover, which is a plastic piece that hides and protects the bolts.
