"Ryan was perfectly on-time and was a plumbing scholar and a gentleman. We had a simple drain replacement under a new sink. Going to Western saved me at least another day of trying to figure out proper parts and doing the install myself, and it also saved my wife's ears from hearing my salty language."

"Conrad was so helpful and honest and thorough. He gave me a true assessment of my current system, what needed to be done to fix it, and didn't try to upsell me on any expensive repairs or new installations. Would recommend them to anyone."

"This was my 3rd plumber for the same request. I had 2 TOTO toilets to install in slab floor. The 1st plumber came and couldn't install because his drill bit broke(?) but he complained about toilet throughout. He changed shut off bulb and hose and charged me $145, but couldn't install. 2nd plumber came but didn't even want to touch the toilet because they aren't familiar with TOTO toilet. Finally, called Mclay, knowing they can do the job but afraid the cost, but it was just reasonable charge, same with other company would charge!! Chad came and he installed 1st toilet about half the time 1st plumber was struggling trying to install but failed. The 1st plumber actually drilled in wrong place. He checked if there's any leaks, double, triple times to make sure. Added extra washers no extra charge, Chad just made sure its properly working. Very efficient and excellent!! He was very polite and pleasant. He gave me discount also. I just regret wasting time and money on some plumber who says they do but can't. And very happy that Chad came to rescue, done job so quick and efficiently. I know for now on who to call in need of plumbing problem. If anyone need plumber, Mclay will help you."

"Robert and his crew were really wonderful and did a great job with our patio! Robert was always on time and did the project in the specified amount of time and for a reasonable price. This was a big job where the original concrete patio had to be removed and a new flagstone patio installed in its place. The new patio really pulls the whole backyard together and is such a great addition! Robert was also very good about making adjustments at our request without hesitation. We will be hiring Robert in the near future for additional home improvements!"

Foundation Drain Installation questions, answered by experts

Not all window wells have a formal drain, but they all require a method for water to flow away from the window. Some wells are connected to an interior or exterior drain tile, which is the most effective solution. Others rely on a deep layer of gravel or crushed stone that allows water to filter down into the soil.

However, if a window well lacks a proper drainage system, it can lead to basement seepage, costly water damage, mold growth, and potential foundation damage. This is especially true in areas with heavy rainfall or expansive soil.

If your window well doesn't have a drain or is not draining quickly enough, you have a few options. For gravel-based systems, the stone may have compacted and needs to be improved. For a more robust solution, you can hire a plumber or window installer to connect the well to a drainage system. This can also be a DIY project using a shovel or auger.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to move wastewater and solid waste to the municipal sewer or septic tank. However, for fixtures located below grade (e.g., in a basement), gravity is not sufficient.

The purpose of a sewage ejector pump is to actively pump this wastewater and solid waste upward into the main sewer line. Without an ejector pump in this situation, wastewater would have no way to exit and would eventually back up, causing a sewage overflow or flooding in your basement. If all of your home's plumbing is on the main floor or higher, gravity can handle the drainage, and an ejector pump is not needed.

Your sump pump will discharge water through a discharge line or pipe. The discharge line should be placed at least 10–20 feet from the foundation to avoid any issues.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.
