"Couldn't have gone better. I found Rodrigo on Angi, but then discovered that several of our neighbors had used him and loved him. We were going to get multiple bids but after talking with him, he was so nice, knowledgeable, and reasonably priced that we decided to go ahead on his removing the concrete. We then came up with the idea of using that concrete as a broken concrete entryway path and decided to have him do that as well when our backyard unit was finished. Couldn't have made a better choice. He's creative, conscientious, meticulous, notices things that we hadn't thought of and just a terrific person to work with. Our broken concrete entryway has different colored stones in between and it looks great, a wonderful entrance to the new house. Rodrigo also did a surface for a bike shed we're building and a walkway to and platform for a hot tub. We'd recommend him to anyone."

We offer same day repairs and emergency services, with over 2,600 five-star reviews by our customers in Tacoma, Federal Way, Auburn, Puyallup, South Hill, Kent, Bellevue, Redmond, Seattle, Olympia and the nearby areas. We take pride in serving King, Pierce and parts of Kitsap and Thurston Counties for both residential and commercial needs with honesty, integrity, and dedicated service.

"had a deeply frustrating experience with Hunt’s HVAC Services that reflects a serious lack of professionalism and customer care. They contacted me early last week to schedule service for my HVAC system, and I agreed to their preferred date—the following Monday. I received a confirmation email on Sunday and a reminder Monday morning for the upcoming afternoon appointment. I drove 1.5 hours to the service site, only to be met with confusion and poor communication. When I called at 12:30 to ask for a specific arrival time, I was told the technician would contact me 30 minutes before arriving—but they couldn’t give me a time estimate. I waited another 2.5 hours before receiving a call informing me that no technician would be coming at all. My only options were to reschedule or cancel. I asked to speak with a manager and was placed on long hold. Eventually, I was told the manager was “too busy” to speak with me and would call me later. That call never came. This experience was a complete waste of time and resources, and the lack of accountability was appalling. Hunt’s HVAC Services failed to honor their commitment, communicate effectively, or show basic courtesy. I strongly advise others to stay away from this business."

French Drains questions, answered by experts

This scenario is unlikely but technically possible. Clogs that result from water-soluble materials like toilet paper or human waste may eventually break down in the water and allow the water and waste to flow freely once again. A more likely scenario is that you’ll have to learn how to unclog a toilet or call a plumber.

You should inspect and clean a French drain at least once per year. However, if the drain accumulates a lot of debris and sediment, it may require more frequent cleaning. If you notice reduced drainage or any signs that it is clogged, it should be cleaned as soon as possible.

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.

Clogs in a sprinkler valve can be caused by various factors, including debris in the water supply, sediment buildup inside the valve, or damage to the diaphragm. Debris and sediment can accumulate over time, obstructing the valve's passages and impeding water flow. Damaged diaphragms may develop tears or holes, leading to blockages and affecting the valve's ability to open or close properly. Regular maintenance and cleaning can help prevent and address these issues, ensuring your sprinkler valve operates smoothly.

Some experts estimate that descaling your cast iron pipes can extend their lifetime by upwards of 50 years, although there’s not a lot of research to prove it. But we do know that without proper maintenance, cast iron pipes can quickly rust—leading to more expensive issues like burst pipes or main line clogs.
