"Exchanged messages with Mike to describe work needed, replace an outdoor faucet and shutoff value (previous faucet was leaking). He gave an estimate, reviewed work to be done. Replaced outdoor spigot with a frost-proof spigot, put on new value. Quick test and validation. Professional, efficient and happy with work done! Thank you Mike !"

"Installers arrived on time and worked very hard and efficiently. Project took two days since in addition to the shower conversion they also installed a new LVP floor and a new toilet. Rafael and his assistant were top notch and left the house and work area clean even at the end of the first day. I highly recommend them if you are considering a project. They made an effort to minimize the time water was shutoff as well."

"Tara came out to my place promptly to look at the job. She was good to talk to, and made some suggestions that I decided to follow up. The workers showed up as scheduled and worked fast. Clean up from the hedge trimming was awesome, and later I found that they had also done some needed trimming that I hadn't asked for. I'm very happy."

"Excellent service. I had a sump pump system put in 10 years ago by Rescon. Never had any problems with it, worked great. This weekend with all the rain the pump stopped working. I called there emergency line and a service technician called me back in less than an hour. They were at my house in less the 2 hours fixing my pump. They did charge me an emergency dispatch fee for the service call but I guess that s expected on a weekend. Overall it was excellent service and I am very happy I chose this company."

"Getting a walk in tub is expensive no matter who you use. My experience thus far is with installation only and I must say my install went great. It has been over a month and no issues with my tub so I cannot comment on repair process with American Standard."

Affordable Plumbers FAQs, answered by experts

Yes, many services include necessary plumbing adjustments. Confirm with your installer.

Replacing cast iron pipes when they’ve reached the end of their life span is key to preventing leaks and clogs. Over time, cast iron pipes corrode and experience pipe scale, which thickens the inside of the walls and increases the chance of clogs while also decreasing water flow. As the material deteriorates, you could experience costly leaks that increase reparation expenses. 

Cast iron can last between 50 and 75 years, but it’s still a good idea to check for leaks as your pipes approach the 25-year mark, as pipes can already show signs of deterioration within the first three decades.

Running hot water through frozen pipes can help thaw them, but it's not always a guaranteed solution. To prevent pipes from freezing in the first place, it’s crucial to open the hot and cold faucets connected to the frozen pipes and allow a slow, steady stream of water to flow. Additionally, applying gentle heat using a hairdryer or heat tape can expedite the thawing process. If the pipes remain frozen, professional assistance may be necessary to prevent damage.

In most cases, it’s better to repair a toilet than to replace it. Fixing issues like low water levels, running water, and flushing problems is less expensive than buying a new unit. Start thinking about replacement if the toilet is cracked, using excessive amounts of water, or is over 15 years old. Newer models are more water-efficient and clog less often than older models.

When learning how to design a plumbing system for a house, it's helpful to know that ABS pipes have fallen out of favor because they are less safe and efficient compared to alternatives. ABS pipes are made from a chemical called bisphenol (BPA) that may cause neurological and hormonal effects. Due to the fact that it has a lower melting point, ABS can also be flammable in high-temperature situations. Finally, ABS is prone to warping caused by heat and UV exposure. It can also fracture in frozen conditions.
