"Generally, it went well. I was told exactly what they were going to do before they did the work. The first day, I was taken aback at the price of the work, I assumed the original request would not be such an ordeal, so they allowed me time to consider the work and price while they fixed the toilet. I did decide to go ahead with Top Contender, and I am glad I did. They opened up the wall opposite the faucet, shower head, etc, and found rotten wood, which they replaced, cut away old pipes that were causing electrolysis, reinforced the pipes with staples(not sure of the technical terms), and patched up their work after replacing the shower head, faucet and spout. They were thorough. I had to add additional work to the kitchen faucet problem after cleaning under the sink and notice a crack on the pipe and ask if they would replace it after they fixed the faucet. The issue with the faucet was that it looked like it should have been stuck in the wall a lot further. I wanted to add tile on the wall behind the sink and the faucet stuck out of the wall. The exposed section was covered nicely and I am able to slide the piece, install the tile, and slide the piece back to the wall - problem solved. They did remove the plumbing underneath the sink with new, ABS p-trap assembly. Before they worked in the bathroom, they papered the floor from the front door through the bathroom, used any parts I had on hand, and aired out the bathroom during the entire time. They did clean up, better than most.. not perfect (but I would only notice that).."

"Ever since we purchased our home, we’ve used Louie and ASO Plumbing. They are simply the best. We’ve used them for everything from water heater installation to sewer line replacement, and we couldn’t be happier with the work. They assess problems efficiently and explain the issues in a way you can clearly understand. Not only do they provide excellent service, but more importantly, they provide peace of mind."

"Art was extremely helpful and accommodating at every step of the project, from bidding through scheduling and even some additional work we needed a few weeks later. The team worked efficiently, doing a new main line install (going under our sidewalk and concrete without any demolition), re-piped the horizontal pipes under the house with copper (they were 100 year old galvanized), and setup a new shut off and regulator outside. They did everything in a day and cleaned up nicely. When we had other contractors working on our foundation 2 weeks later, they bent over backwards to get plumbers out the next day to make some fixes to drain pipe and at an excellent price. I got quotes from three companies and Repipe Pro was the most competitive and also great responsiveness from Art and his wife Thelma who run the business. To anyone looking for a repipe of a home or new main line or having drain work done, I definitely recommend contacting Art at Repipe Pro."

"Installation went smoothly. I've had the system for about 5 years and I recommend it highly. The water tastes great. We don't buy water anymore. Our pipes are protected from mineral buildup. Very pleased with our purchase."

"In 2013, AAP replaced my toilet with a new one (that they recommended). Over the past 4 years, that toilet has plugged up 6 times and I had to pay $125 each time to have AAP unplug it. I complained that they obviously installed a terrible quality toilet. The manager agreed to replace the toilet with a new one that was better quality...for free. No cost for the toilet or the labor to install it. Although I was pretty angry that they recommended a terrible toilet, I appreciated them replacing it for free. It was the right thing to do. Except for this issue, I have been very happy with AAP's service. They have always been able to come the same day I've called (even nights and weekends). And the service guys are all very nice and capable. I will continue to use them for all my plumbing needs."

Sink Installation FAQs, answered by experts

Because it’s an engineered stone, quartz composite is much denser than other natural stone alternatives. For instance, if you drop a heavy object in a natural stone sink, there’s a chance the sink could crack, chip, or dent. Quartz’s density means quartz sinks are more resistant to scratches or staining. However, darker quartz sinks are more likely to show scratches or scuffs, and quartz sinks can stain over time.

The standard kitchen sink size is typically 22 inches by 30 inches. However, kitchen sinks are available in a wide range of sizes to fit different kitchens, commonly from 25 to 39 inches long, though you can find even larger or custom sizes. When choosing a replacement, the easiest option is to select a sink that matches your existing one's dimensions. If you decide to install a larger sink, you will need to enlarge the cutout in your countertop; be sure to use the template that comes with the new sink to ensure a proper fit. Installing a smaller sink can be more complex, as it may require replacing the entire countertop.

Yes, a toilet, sink, and shower can share the same vent. This is a common installation method that can simplify plumbing and save space. However, there are important considerations. The vent and associated plumbing must be large enough to handle the demands of all fixtures without compromising the vent's effectiveness. Additionally, the toilet should always be located downstream of all other fixtures. Because requirements can vary and space might be limited, it is essential to check your local building and plumbing codes and consult with a qualified plumber to ensure the installation is done correctly.

The main cause of bathroom leaks is seals and connectors that loosen or deteriorate over time, causing leaks to develop. It's important to stay on top of your bathroom materials, as toilets, showers, and sinks all have different lifespans. Toilets and faucets last between 10 and 15 years on average with regular maintenance, but different parts may have shorter lifespans than others.

If you need to repair part of your plumbing, it will cost an average of $330. The cost of plumbing repairs is influenced by several factors, including the type of drain and the specific repair needed.
