"Ehly Renales was very pleasant and professional. He gave a clear estimate and we discussed repair of AC unit versus replacement. I decided with repair. He finished the job in 1 hour and AC was working. Also, he was very respectful about wearing shoe coverings when he entered our home and he also wore PPE(to protect himself and my family because of Covid-19 pandemic). In short, I definitely recommend this company and Ehly for AC repair"

"I have been a Moore Home Services customer for well over 5 years. They have always treated me as a valued customer from Customer Service Team to the Technicians. The Moore team is professional, friendly and extremely knowledgeable. They communicate problems and work to be done in simple layman's terms. Technicians Marcos Sosa and Sebastian fixed my clogged sink that now works great. They were even able to come earlier than scheduled. As a senior citizen, living on my own, this made my day. Thank you Team Moore. Cindy"

"Groundwork’s did a great job on our house. Luis G was an amazing Forman with Ken H and Mark P all waterproofed under our house. They worked quickly, efficiently and thoroughly left all areas in tact and clean. Luis communicated very clearly about the all aspects of the job until it was completed."

French Drains FAQs, answered by experts

With a one-way cleanout, you can access your sewer line from one direction. Depending on the way it curves, a plumber can either access the side of the pipe that goes into your home or the side that goes to your yard. On the other hand, two-way cleanouts allow pros to access both sides of the sewer line, thanks to their dual-pipe design (they’re usually U-shaped).

If you have a sink stopper, it can feel more challenging to clean the drain without removing it, but here are a few simple steps:

  • Pour ½ cup baking soda into the drain using a funnel

  • Pour 1 ½ cups vinegar into the drain

  • Close the sink stopper for 15–20 minutes

  • Open the drain

  • Pour 2 cups of boiling water down the drain (be cautious as boiling water can damage some types of pipes)

If the drain isn’t unclogged, repeat the process.

Yes, frozen pipes can prevent a toilet from working correctly. If the pipes are frozen, water cannot flow, which means your toilet tank won't be able to refill after a flush. This will prevent the toilet from flushing again. Depending on which lines are frozen, the ice can also block the drain pipe, preventing water from flushing away.

As a temporary workaround, you can manually add water to the tank for each flush. To clear a frozen drain pipe, you can try filling the toilet bowl or tank with warm water and flushing to help thaw the ice. However, the best long-term solution is to unfreeze the pipes to get your toilet back in working order.

In some cases, operating a snake can damage your drain and pipes. This depends on the overall condition of your pipes and how gently you operate the auger. For instance, older galvanized pipes covered in zinc are susceptible to scratches when using a drain snake. Additionally, it’s common for newbies to apply too much force when extending the snake, leading to scratches and related damage. You can also crack the porcelain with an electric auger if you’re snaking a toilet drain. If you’re using a manual snake or auger, the risk is minimal.

Bleach isn’t likely to help unclog a sewer line. Bleach isn’t useful in this situation because it won’t dissolve the grime and debris in the clog. Instead, you want to use ingredients that will have a chemical reaction to clear out the buildup, like vinegar or salt and baking soda.
