"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."

"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 FAQs, answered by experts

Inspect the pump annually, test the float switch, and clean the discharge line to ensure efficient operation.

In most cases, standard homeowners insurance policies do not cover damage from a sump pump failure or overflow. Coverage for water damage is often limited to sudden, unexpected events like a burst pipe that was not caused by negligence. To be covered for sump pump issues, you will likely need to purchase a specific rider, endorsement, or additional water backup insurance. If your insurer offers this type of coverage, they may require proof that your sump pump is regularly maintained.

When a backflow valve fails, wastewater will flow back into your system, contaminating your drinking water. You’ll immediately notice backflow valve failure from a rotten smell and brown water coming from faucets. Get in contact with a septic pro or a plumber immediately if you suspect this has happened to you.

Yes, many providers offer warranties for new pumps and labor. Confirm terms before scheduling.

If your water pump fails, the first step is to turn off the power to the pump to prevent any further damage. Check for common issues such as clogs, electrical problems, or mechanical failures. If you cannot identify the problem, contact a professional who specializes in pump repairs. Prompt action can help minimize damage and repair costs.
