"The folks @ Mike Counsil have done work for us in the past, including the heater installation and unclogging/cleaning a backed up drain. Any time we've had work done by them, they are always right on time and very professional. They get the job done and clean up after they're finished to ensure there's no clean up for the customer. I highly recommend them for all of your plumbing needs."

Customers say: Quality work

"ICR Plumbing provided exceptional service. I had a major problem where water was coming through the garage from the bathtub drain, "waste over flow " Israel was extremely knowledgeable and fixed the problem in less than a day's time. First he had to remove a heavy bookcase that was nailed to garage wall to access area, he removed and replaced all the sheet rock and pipe connected to bathtub. He did an awesome job and was very personable and honest, His price was reasonable. I would recommend him to anyone in need of home improvement, as he is knowledgeable in many areas and does great work! I will definitely call him again on more projects! He is The Best!. He went above and beyond his call of duty and helped me cut up other stuff with his electric saw so I could go to the dump. He even emptied my lawn mower bag for me which was not part of the job. He also is an expert at plumbing and has many years of experience."

"At first the company's name made us imagine they were just about clearing clogged drain lines, but we got superb service on a project to replace leaking shower faucets in the bathroom. Gerardo came to see what was needed and was very helpful in finding a quick and cost effective way to source the materials. He was completely committed to taking care of his customers. He returned to do the installation at the time we had agreed would be convenient for us, despite having been up working till all hours of the night on another emergency job. He even spent the time before returning to his emergency site to check and make sure the existing shower head was free of grit and working as it should. We absolutely will want this company, and him, for any future projects."

"Gabriel Nieto of GN Plumbing did a fine job. He was able to visually detect a leak where the line from the propane tank enters the house, and pressure tested the gas line from the propane tank to the house to confirm the leak. With the help of his assistant, he repaired the line (replacing worn out portions of the line) within a couple of hours, confirmed there were no other leaks in the line (via additional pressure testing), and re-lit the gas furnace and water heater. Only complaint is the extreme expense ($890)."

French Drains FAQs, answered by experts

Yes, chemical drain cleaners contain sulfuric acid and hydrochloric acid, both of which are not only dangerous to your health but also extremely caustic. Drain cleaners will corrode your pipes and could lead to destroyed drain lines, especially if the chemicals interact with the piping for long periods. Unfortunately, this extended interaction is likely if you’re dealing with a clog, as the drain cleaner will have just as much trouble as water does moving through your plumbing system.

Yes, drains are one common entry point for water bugs. However, water bugs may enter your home through various locations including doors, windows, pipes, and vents. Water bugs are drawn to the dark and moist atmosphere drains provide, and can easily find their way into your home through sewer drain pipes. You can stop water bugs from entering through drains by regularly cleaning your drains and repairing faulty drainage systems.

Clean regularly with non-abrasive cleaners, avoid pouring grease down the drain, and check for leaks under the sink.

You can unclog an AC drain line for free if you already have these household ingredients: water, vinegar, and rags. Alternatively, if you’d rather not deal with the mess, you can hire a pro to clear your drain line. If you go that route, an HVAC service call costs between $100 and $250.

That pungent rotten egg smell coming from your drain is likely the buildup of biofilm—hair, skin, and soap scum that turns into a black sticky mess. In this case, pouring down near-boiling water, baking soda, and white vinegar will remove the smell. Keep in mind that a rotten egg smell is occasionally a sign of larger sewage line clogs and other related issues.
