"The French drain is working well but the rest is marginal. We have some water intrusion in an area that was supposed to be waterproofed, we do not have the molding installation for the downstairs flooring that was promised, and the dehumidifier has not rid the house of the mold smell, as was promised by Kevin, the sales guy. In addition the crew, and sales person, never noticed that the dehumidiifier and sump pump were installed in an area without an electric outlet, resulting in yet another expensive job to add to the $14,000 bill from JW. Also the billing practices with this job were shaky at best - just now, five months after the job was fully paid for, we received a mysterious bill for roughly $350 supposedly for some error that was recently discovered! So overall most of the job got done satisfactorily but it was a far cry from the exemplary work and service I received from John's several years ago when our encapsulation system was installed. I can only give an overall rating of OK since I know there must be better out there."

"We recently had our hot water heater replaced by Colin at Independent Plumbing, and I can’t say enough good things about the experience. Colin was incredibly professional, responsive, knowledgeable, and easy to work with from start to finish. He communicated clearly, showed up when promised, and completed the work efficiently and with great attention to detail. It’s hard to find someone who takes this much pride in their work and truly cares about customer service. The entire process was smooth and stress-free, and the quality of the installation was excellent. I would highly recommend Colin and Independent Plumbing to anyone looking for honest, dependable, and top-notch plumbing service!"

"I called Speedy Septic July 13, 2017 to schedule pumping of my septic tank. The earliest available time was August 2 between 8 and 9 am. As that date approached, the weather was very hot and I offered to have them arrive as early as possible on the scheduled day. They arrived promptly at 7 am. It required a minimal amount of digging to uncover the septic tank. In addition to the pumping equipment, they used their own hose and water during the process, although they did ask for a hose or at least a water spigot. I did not have running water outside at the time, as I had advised when I made the appointment. The crew of two was polite and efficient and discussed with me their findings about my tank and drain field and provided recommendations for the future."

"he went into the crawlspace somewhat reluctantly,i felt. he came out several minutes later and complained that his overalls were getting damp in the front,so he didn"t do the inspection.he then quoted the cost of doing a drain in the crawlspace.we did not want a drain field under the house,we wanted the water from the hill above us to be drained away from our home.he also offered us a small discount if we signed right then.we were not very impressed with the way things were handled.

French Drains questions, answered by experts

You should hire a sewer service professional to unclog a main sewer line with tree roots. Tree roots can grow into the main sewer line, and this problem requires a specialized hydro jet, or rooter, that is powerful enough to clear the roots. The tree can also damage the main sewer line, and a professional will need to make repairs or replace the damaged sections. Sewer line replacement costs about $60 to $250 per linear foot.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

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.

Biodegradable drain cleaners use naturally derived ingredients, such as baking soda, vinegar, and boiling water, which bacteria and other microbes can break down. Unlike conventional cleaners that rely on corrosive bleach (sodium hydroxide), biodegradable options are gentler on fixtures and less harmful to the environment. Because they don't release harmful gasses, they are also safer to use, especially in households with children, and do not require the same safety precautions as bleach-based products.

Several signs can tip you off to a clogged dishwasher drain. At first, you may notice that it’s taking longer than usual for the dishwasher to drain, or you may hear gurgling sounds during the draining part of the cycle. You might also notice water backing up into your sink or excess food at the bottom of the dishwasher after a load. The most obvious sign, though, is seeing standing water at the bottom of your dishwasher after the cycle has finished.
