"I reached out late at night. Gotta call at 7am. They showed up at 9 and figured out quickly why I didn't have water coming from the well. My pump was burned out. These guys busted their butts in extreme heat and humidity and got my well up and running by 4pm. 311 feet of new hose electric and the pump for a reasonable price. Super nice guys! I would recommend this company to everyone"

"Sometimes you just get lucky. We got super lucky when we hired D. Rohde to fix our A/C. Our technician Mike A. showed up with a helper/trainee, explained the estimate fees and then went to work. In less than 10 minutes he was able to identify the defective part, return to the truck for a new replacement part, and then install the new item. In under 30 minutes our main central A/C was back up and running. The second (upstairs) central air unit took another 10 minutes to diagnose and then about 40 minutes of grueling work in a super-hot attic to drain out the overflow tray, cut, blow-out the drain line, and repair the drain. Once drained, the unit is again working perfectly. It is great when a technician shows up and really is an expert. Mike A. is such an expert and also extremely friendly. Brandon, the assistant/trainee was also great and someday will make a great technician using all the knowledge learned from Mike's expert tutelage. I will recommend these guys to everyone I meet."

"I had a plumbing leak since February 2024 whereas the leak was coming from my bathroom shower leaking into my kitchen, when I immediately contacted my home warranty American Shield, they never provided me with a Plumbing contractor. From February 22, 2024 until March 24, 2024, I continued to have leakage. American Home Shield then told me they had no contractors to assist me with my plumbing issues and therefore wanted me to identify a Plumbing contractor and then submit the diagnosis to them for review and approval. I then identified Royal Class Service and they diagnosed the leakage as a Shower Valve Replacement whereas they would need to open drywall from the closet to gain access for repair. The estimate from Royal Class was over $2,000.00. American Home Sheild then sent PROSERVICE HVAC & PLUMBING for a second option located in Connecticut. They stated that Royal Class inflated the cost repair and this Pro-Service Company was supposed now take over the repairs. I waited three more weeks because when I called Pro-Service requesting a date for repair they continuously told me they are waiting for valve they ordered from Home Depot. They are the worse!!! I'm Disabled and was out of my shower usage for three months. Well on a Thursday of early May, I happen to see Neighborhood Plumbing truck and contacted Anthony (contractor). Anthony came to home so professional and concerned to assist me with the well overdue plumbing issue and Neighborhood Plumbing repaired this in less than two hours at a price that was extremely fair and far more less than Royal Class quoted and five star professional than American Home Sheild and Pro-Service located in Connecticut. Please don't get taken by these companies. Anthony could have attempted to inflate his prices and robbed me like Royal Class attempted or he could have never come back to repair just as Pro-Service did. But, Neighborhood Plumbing does not have professional integrity they get the job done at a cost that's not ROBBERY! I had a horrible experience with these former companies and I urge you to seek out Neighborhood Plumbing if you need Plumbing, Heating & Cooling Services. Thank you Neighborhood Plumbing,"

"Guys came in and worked. No lollygagging or long breaks or any of that just plowed through on a dirty two-day job and their work made me feel a heck of a lot better about the structure of our home. Did great work. The only complaint is that they did not repair a small basement window casing that they pried open to get materials to the basement. I am sure had I contacted them they would have come back and fixed it, but it was not anything nice to begin with and I was able to repair myself pretty easily so I never even brought it to their attention."

French Drains FAQs, answered by experts

Bleach—even diluted bleach—is not always the safest option for cleaning your drains. With a high pH, bleach can be highly corrosive to many types of pipes, especially when used regularly. When mixed with household cleaners and organic waste, it can also create dangerous chemicals. Remember to use proper protective equipment and ventilation when dealing with bleach.

Pouring drain cleaner down a vent pipe isn’t recommended. First of all, unlike a clog in a sink or bath caused by such material as soap scum build-up, toothpaste, and hair, clogs in a vent pipe are likely the result of debris from trees or even an animal stuck in the pipe. Drain cleaners won’t be able to eat through this kind of material. The cleaner will only become clogged in the vent with the debris, causing even more problems.

A bit of water in the bowl can help unclog a toilet, especially if you're using a plunger. However, if the bowl is full to the brim, you'll need to strap on gloves and remove some of the wastewater in a cup or container so it doesn't overflow when you try to unblock the pipe. If you're concerned about it filling further, manually close the flapper in the toilet tank or turn off the water supply to the toilet.

The drain pump will naturally make a standard operational and draining sound several times throughout your dishwasher cycle. If you hear abnormally loud sounds like scraping, grinding, or clicking, you may have food debris or a piece of glass stuck in your drain filter. Avoid dishwasher repair by always scraping food off your dishes and loading the racks correctly.

The cost to repair a main sewer line clog is about $3,110 on average. The average cost range is  $1,310 to $4,950, but it can go as low as $215 and as high as $9,300 or more. The cost factors for this repair include the severity of the clog, pipe accessibility, video inspection, removal method, permits, pipe material, labor rates in your area, and time of year. Repairs made from outside during the winter can be more difficult due to the frozen ground or during the spring if the ground is saturated from a lot of rain and snow melt.
