"They did a great job fixing our sewer line. All workers were experts of this trade. They kept all the dust concealed in the areas they had to jack hammer in the basement. They used a window well to bring in their tools and supplies. They didnâ t want to haul the mess through the house. Canâ t say enough about their excellent work. I have already told the neighborhood about their great work. Thanks guys"

"The pro identified the exact spot was the water leaking was coming from. He cut the part up of the pipe and replaced it with w good one, explaining every thing he was doing. He tried to make sure there was no more leaking before leaving. He further removed a clog in the drain in a sink where the flow was almost stopped."

Drain Cleaning questions, answered by experts

Biodegradable drain cleaners use naturally derived ingredients, such as baking soda, vinegar, and boiling water, which bacteria and other microbes can break down. Unlike conventional cleaners that rely on corrosive bleach (sodium hydroxide), biodegradable options are gentler on fixtures and less harmful to the environment. Because they don't release harmful gasses, they are also safer to use, especially in households with children, and do not require the same safety precautions as bleach-based products.

If you leave liquid drain cleaner for too long, it will start breaking down your drainpipes. The chemicals in these cleaners can cause cracks, corrosion, and leaks in your pipes. They can also damage plumbing fixtures and even cause environmental damage if left too long without rinsing away.

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.

You can try several easy methods to unclog a drain, one of the easiest and most effective of which is to use a mixture of baking soda and vinegar. This will help dislodge and dissolve the clog to move it down the drain pipes. Pour 1/2 cup baking soda into the drain, followed by 1/2 cup of white vinegar. Dump several cups of boiling water (or hot water if you have PVC pipes) into the drain and let sit for up to one hour. Run hot water to clear the drain.

Food grease, soap buildup, paper products, and tree roots often cause serious clogs.
