With the El Nino event imminent,bay area With heavy rain expected this winter, many homeowners are concerned about damage to their homes due to poor drainage from the rain. This concern has kept drainage contractors in the home repair business busy.

san francisco “The Chronicle” reported that David Wilson, owner of Bay Area drainage system company “Bay Drainage”, said that for drainage engineering professionals, now is a booming time for business. Because people are so worried, every time they watch the news, they are talking about the Holy Child incident. He revealed that the company’s business is fully booked through the end of 2026, and has even received inquiries from as far away as Sacramento and Davis.

But before you panic and spend money on a large-scale renovation, experts recommend that homeowners take a few simple steps that only take a few minutes and are low-cost to check the drainage condition of their homes before the rainy winter arrives.

Rainwater can collect under your home and seep into the old, porous foundation. Jim Gardner, owner of East Bay contractor Jim Gardner Construction, said many homes in the Bay Area are built on soil that has poor water absorption, allowing rainwater to collect under the house and then drain into small spaces in the building’s basement or basement. Homeowners who have converted their basements into a kitchen or bedroom have more concerns than those who have unfinished basements or only have a crawl space below.

Wilson noted that some homeowners who enter small spaces in the basement of their homes after heavy rains will find several inches of water inside. They often choose to install a “sump pump”, a mechanical device that pumps stagnant water from a small space to the outside, and then leave it alone.

However, during the extremely wet winter months of the Santo Niño year, this equipment alone may not be sufficient.

One of the most common methods used by contractors to protect homes from heavy rainfall is to install French drains. It is a trench dug around a house, filled with gravel, and lined with pipes, which essentially collects groundwater and diverts it away from the house.

However, drainage projects are not cheap. According to contractors, the cost of installing a French drain typically ranges from $10,000 to $40,000, while more complex drainage projects can cost up to six figures. Whenever a potential customer calls Ghana or fills out their company’s online form, their first words are often “Christ Child”.

He suggests homeowners take some low-cost precautions before contacting a contractor to ensure their homes can withstand the rain. First, adjust the drainage pipe in the eaves drainage channel to direct water toward the ground pipe and away from the house.

In some older homes, drain pipes carry water directly to the ground, which can cause standing water to accumulate beneath the home’s foundation. The solution is simple: Go to a hardware store and buy some hose, attach it to the end of your drain pipe, and make sure the nozzle faces away from the house.

Additionally, homeowners should inspect their sump pump. Garner said such devices are prone to failure. The inspection method is to fill the sump with water and observe whether the water flow can be released as expected.
