"100% positive experience with Kurt. He instantly responded to my service request to replace a water heater and showed up next day 7am on the dot. Honest guy and much more reasonably priced than other plumbers in the area. Definitely will use him for future plumbing projects."

Customers say: Quality work

"Quick and easy. I've used him before because of great service. Already had everything because my other one broke and drained all over the floor. Probably would have been at least 3-4 hours if I was replacing one that broke because of just not functioning."

We had a very hot and cold experience with Alonso Landscaping.  They were very responsive when we first asked for a quote to remove numerous shrubs and redo all of the landscaping in front of our house.  The estimate came back quickly and was very reasonable compared to other companies.  At that point, we wanted to change some of the plants Ramon used in the estimate.  It took between 3 weeks to a month to get any further response with our changes.  We would call Ramon on his cell, call the main office, and email but get no meaningful response.  Then, Ramon responded, made the changes, provided the new estimate, and got his crew out in less than a week to do the work.  I am not sure what caused the difference between the times when Ramon was incredibly responsive and the period where he was totally unresponsive.

The work itself looks great.  Ramon was very willing to work with us, listen to our thoughts on what we wanted, and put together a beautiful landscape that captured exactly what we wanted and made it look even better than we had imagined.  His crew left a few branches from some shrubs they removed which they could have disposed of, left a very large landscaping stone in the yard instead of in the landscaping, and moved our hose from the backyard to the frontyard without returning it when they finished.  They also broke a feature on our hose nozzle.  Other than those couple small problems, it was great to work with Alonso.

Small jobs welcome

"Central Wisconsin Excavating (CWE) did a fantastic job on our project. They built a solid, well-prepared foundation for our 80,000-bushel grain bin and graded our driveways perfectly to ensure water drains away from our buildings. Their attention to detail, quality of work, and professionalism really stood out. The site was left clean and properly finished, and everything was done right the first time. We’re extremely happy with the results and would highly recommend CWE to anyone needing excavation or site work done right."

French Drains FAQs, answered by experts

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.

Even if the shower drain doesn’t seem clogged or dirty, plan to clean it out about once per month—or more frequently if you or your family shed a lot of hair. It’s a good practice to remove any hair from the drain on a daily basis, as hair can accumulate fast and cause clogs in no time. You may also want to have a plumber thoroughly clean the drains in your home once every six months.

The cost to unclog a drain varies based on the location and severity of the clog. For simple clogs within your home, such as in a sink, toilet, or shower, hiring a plumber typically costs between $110 and $350, with an average of around $200. Snaking a toilet or sink usually costs between $110 and $275, while a bathtub or shower clog costs about $225.

For a more serious clog in the main sewer line, the cost is higher. Clearing a main line clog generally costs between $200 and $600, with an average of about $380. However, prices can range from as low as $100 for snaking a minor clog to over $1,600, particularly if advanced methods like video inspection and hydrojetting are needed for a large or hard-to-reach blockage. Some severe main line clogs can cost upwards of $1,000 to clear depending on factors like the cause of the clog, its distance from an accessible cleanout, and whether the pipe is located beneath an occupied space (e.g., in an apartment building). You may be able to save money on minor clogs by using a drain snake or bladder yourself.

A professional drain cleaner is a plumber or specialized drain cleaner with the necessary tools to unclog drains and tiles to keep waste water flowing out to the septic tank or city sewer for processing. Keeping wastewater from backing up into your home helps keep you and your family safe from potential contamination and sickness. These pros can help resolve nearly any drain situation in a safe and efficient manner.

Start by pouring hot—but not boiling—water down the drain. The heat of the water may be enough to break down the clog. You can also try ½ cup of dish soap or 1 cup each of white vinegar and baking soda. If you choose a chemical unclogging product, ensure it’s appropriate for toilets to avoid damage.
