"Andrew knocked this install out of the park! He replaced an incredibly inefficient hot water heater with a hybrid hot water heater, ran the condensate line through pipe straps screwed into drop in anchors along our basement wall with the cleanest looking final result that surpassed every expectation I had. He was very communicative well within the budget and will be our go to for any future work we need as long as we live in this area!"

"So far, so good. The finished project looks great; it really hasn't been tested yet as there has been little or no rain. Groundwater used to flow through the cellar after heavy rains so we'll see it the subsurface floor drain works. The floor looks good, the price was right (lowest of three bids) and Beth was very helpful and available to answer all my questions. At the moment, I'm very happy."

"Tom Howe and his team are a dedicated professional who takes his work very serious and it shows. A man of great integrity, Tom can sell you more but he won't. He will only sell you what you need. As a real estate agent, I see septic systems on a regular basis that have been poorly installed and failed inspections after just a few years. I have never seen a system that Howe has done that has failed. He only uses the best techniques and products so he can put his name and reputation behind them. As for my personal experience, Tom put a system in at my home and did so quickly and efficiently with no delays or excuses and it looked terrific when it was done despite the mounded look which he was very clever at blending in to the landscape. Take my advise, use Tom. You will not regret it."

"They did a fantastic job! We have had driving rain since the installation and our basement is bone dry. They came on time, were very polite and I'm very happy with the fast train system they installed."

""ABSOLUTELY SUPERB" - Ken and Rowen were contracted to install Round River Rock Stone along approximately 180 feet (both sides) of my driveway. Ken promptly answered my request for an estimate. The next day he arrived to view the job and was very thorough about understanding my expectations for the project, He offered advice and is very knowledgeable about how to do top quality work. After my reviewing other estimates my decision was to go with McAdams Excavating, Ken and Rowen arrived as promised and quickly began meticulous work. Material was excavated to provided a 3 inch depth of stone, landscape fabric was installed, finally the stone. The duo were meticulous in all facets of this project and it looks absolutely gorgeous! Do not hesitate to hire this company!!!"

Drain Pipe Installation FAQs, answered by experts

Yes, flushing a clogged toilet can make it overflow. While flushing the toilet may push enough pressure through the system to dislodge the clog, this is unlikely. Your best bet is to use a plunger and hope the suction can break up whatever is blocking the pipe. If this doesn’t work, use a plumbing auger or call a pro to help.

Flushing the toilet only to realize it’s clogged can cause anxiety. To avoid a clogged toilet, use less toilet paper. If you notice that the toilet is flushing and refilling slower than usual, you can use a plunger to clear clogs in the S-trap. If that doesn’t work, call a plumber to check your system and possibly clear the drain lines.

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.

Yes, you can use hydrogen peroxide to unclog a drain. Instead of using a baking soda and vinegar solution, you can use baking soda with hydrogen peroxide. The process to unclog a drain is the same as with vinegar, but use 1 cup of hydrogen peroxide instead.

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.
