"The owner showed up in under an hour, took a look at the problem, brought in the necessary equipment, went to work immediately and finished the job in under 30 minutes. Chris was polite, knowledgeable and just a very likable worker. Earlier I had asked another plumbing company to come in to snake out a kitchen drain. What a mistake, the other company came in and presented 6 options to fix the clog. They charger me $99 to present solutions from $550 to $5500 (compleate under the sink rebuild). Completely wasted $99. Chris got the drain snaked and cleared for $195. Thanks Chris"

"Very professional, cleaned up after themselves, very quality work.  They had offered me two options for the project, the point of which was to enlarge the area in the stairwell to make it easier to move things up and down to the second floor.  One option was simply to put in a larger, taller door (which option I took), but they also offered to move the staircase and shorten the landing.  The estimate separated the two options so I could choose which or both I wanted.  I have a larger project in mind for this summer, so I will be calling them for this as well.

Drain Cleaning FAQs, answered by experts

If the drain is frozen, the pipes connecting to the washing machine are likely frozen. If the hot water trick doesn’t also unfreeze the washing machine pipes, you can gently apply heat with a hair dryer on the lowest setting. Start at the end of the pipe closest to the faucet to prevent pressure from building in the pipes, and make sure the faucet is open to drain the water as it melts.

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.

Grease buildup, tree roots, and foreign objects often cause blockages. Regular maintenance prevents major issues.

First, find the cleanout pipe in your yard. Unscrew the cap—you may need a wrench to do so. Then, get a drain snake. You can use a non-motorized one, but a motorized snake will make the job a little easier. Feed the snake through the pipe until it reaches the clog. Spin the snake continuously, but don’t try to feed it through the pipe anymore. Keep spinning until you feel it break the clog apart.

Your dishwasher drain hose may have a clog if your dishwasher is full of water, your dishes aren’t getting cleaned, or water takes a long time to discharge into the garbage disposal.
