I had a persistent toilet leak that another highly rated Thumbtack Toilet Repair Pro attempted to fix over multiple sessions by 3 technicians from their team, but their work not only failed to resolve the issue—it actually made the leak worse. Natan came out with his assistant and immediately approached the issue methodically and professionally. After removing the toilet, he identified that the prior installation used incorrect materials and had not been properly secured. The flange and toilet were loose, which explained the recurring leak. He removed all of the improper components, installed a brand-new flange, securely sealed it inside the pipe, and anchored it firmly to the concrete floor with heavy-duty fasteners. He also installed a high-quality wax ring and took the extra step of sealing around it to prevent any future odor issues. What stood out most was Natan’s honesty and frankness—he sticks to his word—and his reliability and dependability. He takes pride in fully correcting the root cause rather than applying a temporary patch, and he stands behind his work with one-year warranty. If you are looking for a plumber who focuses on long-term solutions, quality workmanship, and someone you can trust, I would highly recommend Natan.

Details: 1 toilet • Municipal water (most common) • House

A toilet that was recently installed started leaking from the base. I reached out and, luckily, a tech was in the area and able to come over within hours. A new was ring was installed, toilet replaced and sealed. The work area was left clean. The total job took a little over an hour. The charge was reasonable. Communication was good, although I would have liked the estimate before work commenced.

The work has been split into two visits - replacing the toilet fill valve and the flapper. It would have been more convenient if the technician completed both tasks in one visit without extra charge for 2nd visit. However owner Natan understood my concern and managed a reasonable solution for both of us.

Natan Plumbing was very responsive and quickly handled our need for a new toilet. For an extra charge they picked up the new toilet and disposed of the old one. Very easy to work with them!
