"My wife and I bought a house a couple years ago, and became owners of a radiant heating systems installed more than 20 years ago. Tony and Damian did a great job of understanding how my radiant heating system works, what repairs were needed/what was failing, and where upgrades were needed. They replaced the pump, both expansion tanks, and the neutralizer. Additionally, they noticed the hot water tank was installed incorrectly, and the hot and cold water connections were flipped. It's amazing the system worked, and it's nice to have a system that's correctly installed (even if it's 20 years later!). Additionally, they secured the expansion tanks to the wall (now required by code), replaced the deteriorating copper pipes connected to the neutralizer with plastic (I'm sure this is code now as well), and re-routed the overflow pipes to the outside (rather than the floor!). You can't go wrong with these guys, well done, they're true craftsmen to the trade."

"I highly recommend this company!!! He responded within minutes of my searching for a plumber. He came the next day and installed a new tankless water heater. He also found a faulty electrical outlet and repaired it as well. Quality workmanship. I will keep his number. His name was Harry."

"Several months ago, I noticed that doors in my house were no longer closing and latching. Specifically, my front door no longer locked completely. Once I got it fully locked I could no longer open my front door anymore, so I knew I had foundation issues. I called Bay Area Underpinning to come look at my foundation and do some measurements. We discovered that my front living room was sinking approximately one and a half to 2 inches. The crew, Lance Sladek, Jake Hall, and Eddie Shaw, crawled under my house and dug 30 to 40 foot holes in the ground to install piers that would lift my foundation. These gentlemen worked in very cramped dirty conditions in 90-100° weather. I was extremely happy with their work and their dedication to doing the job correctly. My after the foundation lift, my front door as well as several other doors in my home were able to close and latch again."

"Now for the positive experience.  I called Clearwater Plumbing and left a message.  Larry returned my call within 2 hours.  Larry was very pleasant and answered all my questions.  I purchased all the material for replacing two toilets.  I just needed a quote for labor.   Clearwater Plumbing provided a very fair estimate.  I was also able to use Clearwater's coupon on Angie's List that saved me 10% on labor.  Larry scheduled to provide the service two days after I accepted their estimate.  Larry provided a two hour window for their arrival.  Tyler came to provide the work.  He called 15 mins before he arrived.  He wore shoe covers in my house which I really appreciated.  I have changed toilets before but since I had major back surgery my wife does not want me to get injured again.  I occasionally watched his work. Tyler did not waste any time installing the two toilets.  He completed the work on-time per the quote.  Tyler did a professional job and cleaned up the area when he was done.  I would definitely use Clearwater Plumbing again for any plumbing work.  I would also recommend them to all my friends."

"I was very satified with the work done by M&M. M&M determined that my shut-off valves did not need to be replaced, just tighten. After the job was completed we reviewed some other work that I was thinking of doing and eventually hired M&M to complete this additional work."

"There was not much communications between David Carney and the installers. The installers had to come back second time to complete the job and the quality agreed. David Carney has a superior salesmanship. However, after the deposit was made, I was not able to reach David for questions. He did't answer your voice mails and email or going through his office. c"

"Bryson Heating and Air showed up on time! Gave me a reasonable bid. Installed a new unit! Cleaned out my old ductwork and took time after to show me how to clean my unit. Since I live in the country, “we got dirt!”! Joe himself over saw the whole process. Highly recommend! PS Joe also sold me a 25 Kilo Volt Solar panel grid. Saves me over $1000 am month. Solar is the way to go! Anything to save money right now."

"Anthony was awesome. He was early. He was fast. He didn't try to get over on me and charge me for anything that I didn't need. I would hire this company again, and probably will when I change out some other sinks. Great experience."

Sump Pump Installation questions, answered by experts

Installing a battery backup for your sump pump is recommended, particularly if you live in an area with frequent power outages or severe rainstorms. A sump pump requires electricity to function, and a battery backup ensures it can continue to move water out of your home if the power goes out, providing crucial protection against flooding. Additionally, frequent power outages can create electrical surges that might damage the sump pump's motor. A battery backup system offers an additional layer of protection, ensuring your basement stays dry.

Test regularly, clean the pump, and inspect the discharge line to ensure efficient operation.

If you’re wondering if your home even needs a sump pump, consider whether you’ve struggled with flooding issues in the past. If your house is in a flood-prone area, your yard has poor drainage, or you’ve dealt with any other water problems, then it’s likely well worth it to replace your old sump pump with a new one.

If your sump pump isn’t engaging, it might be clogged with dirt and debris. Check to see if the fitting lid is loose and has been letting debris in. Next, check the float and make sure it’s not obstructed by rust or gunk, which results from insufficient maintenance. Tangled wires or damaged switching systems can also stop your sump pump from engaging.

Repairs typically take 1-2 hours, while replacements, depending on accessibility, may require up to 4 hours.
