How to Choose a California Basement or Crawl Space Company

Wet basements and crawl spaces are a constant source of worry for homeowners. If you’ve experienced pooling water on the basement floor, excessive moisture in the crawl space, or cracks in your foundation or high humidity, it’s worth consulting with a professional basement contractor. An ounce of prevention can prevent a more serious problem. When the environment below the first floor of your home is wet, damp or humid, the resulting moisture and mold growth can damage building materials and stored possessions, pollute the indoor air, and risk the health of those living in the home.

Look for expertise, training, and experience.

When you choose a basement contractor in the Basement Systems network, you get a local company trained in and committed to the best waterproofing practices. Each contractor listed here is an expert in the diagnosis of sub-grade moisture problems as well as the design and installation of proper drainage, moisture and humidity control, and basement materials. Say good-bye to your wet basement with the best basement waterproofing in your neighborhood!

Why do California Basements Get Wet?

Weather factors: Californians keep a keen eye on the weather to understand the weather risks they may face in any given year. The level of snowpack and rainfall can vary, leading to droughts or above-average precipitation. In 2017, the Sacramento region experienced the “wettest year in a century” (Sacramento Bee), in 2005 the rarer "Pineapple Express" precipitation phenomenon dropped almost 25 inches of rain in the Santa Barbara area, and a milder instance of the same phenomenon caused plenty of damage in 2018.

Of course, you don’t have to experience a serious flood to worry about your basement. A short heavy rainfall can overwhelm a sump pump and the result can damage a basement in a few hours. 

Basement construction factors: Basements were never designed to stay dry all the time. They serve as a buffer layer between the living space in upper floors of a home and the earth. This makes them subject to hydrostatic pressure, which is a fancy term for the moisture in the soil that presses against the walls of a basement and overtime creates seepage and downright cracks in the foundation. The joint where the floor meets the wall is an especially vulnerable point in basement construction.

Whether your home is in the Bay areaSacramentoSanta Barbara, or Southern California, your basement or crawl space is vulnerable to water intrusion. Water from the soils surrounding your home can seep through basement walls. Cracks in the foundation, rusty windows, issues with the original construction of the basement, or a deteriorating exterior drainage system can lead to water intrusion, high humidity and leaks. If your basement is experiencing any of these issues, it’s time for a consultation with a professional contractor with experience in fixing basements, crawl spaces, and foundations.

    Customer Testimonial

              thing we never realized that there was an underlying musty smell coming from somewhere within the home. When we first saw our house, we never noticed such a thing, because the smell of new paint covered the musty smell.After highering cleaners to buying air filters to filter the air, the underlying smell of must would still drive me crazy. After much research, I discovered Saber, and at the time of getting them, I was looking to do an encapsulation. Saber sent, over Paul and he inspected my foundation to find the source of the smell. There was a part of the crawlspace that had more moisture than usual. They also discovered a weak point in my foundation.I did not get an encapsulation because they identified the problem by finding the origin of the moisture, and I needed to have that addressed before having the encapsulation installed. However, I paid Saber to re-enforce my foundation. Paul helped me identify that the gutters were the problem on top of exactly where the water was flowing in the crawlspace. Without their help, I would not have found where I needed to remove the rotted wood and fix the gutter on top of them, re-enforcing my foundation. Saber saved me over $100,0000.00+ because if they hadn't found the source of the problem, the moisture would have further damaged my house, and the foundation would have eventually cracked.In the next year or two, I'm looking to have them encapsulate my crawlspace. Saber's customer service, as well as their work ethic, is stellar. After having four other professionals check my place, no one could find the exact problems outside the service they offered. I recommend Saber for quality service and an ethical approach to finding your crawlspace or basement needs!
