"The gentleman who came to my home were absolutely great! Explained everything and made sure I was happy with the work every step of the way. I was nervous in the beginning but my fear subsided after Robert Charlesworth, Marcelo largo, Isaiah belcher and Johnathon Lopez made for a great experience. The attention to detail and dust control, tapping off areas they felt I wouldn’t want getting dusty exceeded my expectations! Thank you for your hard work and kindness. Trucks looked awesome new as well as tools and equipment. Great job guys!!"

"Outstanding! John took our vision and brought it to life in a way that went beyond anything we could have imagined. What could have been a simple repair turned into a complete transformation. The stonework they created not only improved the look of our home but made it stand out in the neighborhood. People keep stopping in front of the house to admire it. The quality, craftsmanship, and attention to detail are second to none."

French Drains questions, answered by experts

There are several signs that can indicate your leach lines are broken, failing, or in need of repair, including puddles of water or a marshy consistency to the ground above or around the pipes, slow drainage or plumbing backups inside your home, and noticeable odors or gurgling sounds coming from your leach field. Keeping your septic system properly maintained, including having your septic tank pumped at regular intervals, can help ensure your leach lines stay in good working order for a long time.

A saturated leach field can result from various underlying issues, so it's best to call a professional septic company to diagnose and treat the problem. Depending on the cause of the saturation, potential fixes include pumping out a full septic tank, adding more bacteria to the tank, or regrading the soil to fix low spots. It may also be necessary to reroute rainwater and runoff away from the leach field using gutters, downspouts, and extenders. Once the primary issue is resolved, planting specific types of vegetation over the area can help absorb excess water. In more severe cases, you might need to install a larger septic tank or replace the leach field entirely.

It is generally not recommended to pour hot or boiling water down a drain to unfreeze pipes due to significant risks. In some cases, the sudden temperature change can cause more ice buildup or produce steam, which increases pressure and could cause the pipe to burst, leading to costly damage and potential burn injuries. While hot water might help with a partially frozen drainpipe, it is unlikely to thaw a completely blocked water pipe further down the system. Additionally, boiling water can damage plastic pipes over time. Safer and more effective methods include using a space heater near the frozen section or applying hot towels directly to the pipe.

Sometimes, the drain is just too clogged—thanks, stubborn hair and soap scum. In this case, you’ll need a more powerful drain cleaner than you can DIY safely at home. But this doesn’t mean you have to choose a traditional drain cleaner. 

You can find biodegradable drain cleaners at your local home improvement store or online for those drains that need a little more oomph. 

While on the hunt for a formidable drain cleaner, the best options are non-chemical clog solutions that combine enzymes and bacteria.

If you want to avoid using a snake to unclog a drain, or if you don’t have one, try vinegar and baking soda. Pour 1 cup of baking soda down the drain, followed by 1 cup of white vinegar. Wait for 15 minutes, and then run hot water (but not boiling water) down the drain to see if the clog is clear. Repeat multiple times as needed.
