Waterproofing Services: Get Your Property Ready For Rain
The National Oceanic and Atmospheric Administration (NOAA) is forecasting a super El Niño event for the 2026-2027 winter season, and for Southern California residents, this could translate to extremely heavy rains. At Thome Waterproofing, we recommend that all homeowners batten down the hatches, so to speak, and schedule any necessary waterproofing services as soon as possible.
While property owners are encouraged to schedule a comprehensive roof inspection and handle tasks such as cleaning out gutters and downspouts, they often overlook essential waterproofing tasks, such as the following, all of which can help reduce the risk of moisture damage or large-scale water damage.
Balconies must be properly waterproofed, especially when they are built over a living area or connected directly to the home. A reliable waterproofing system protects more than the balcony surface—it also helps safeguard the framing, walls, ceilings, and rooms below from water intrusion.
As professional waterproofing contractors, we are often called to correct balconies that were not properly waterproofed during installation. Missing or incorrectly installed flashing, poor drainage, and inadequate waterproofing membranes can allow water to collect on the balcony and seep into nearby walls or the structure below. Over time, this moisture may contribute to dry rot, mold growth, damaged finishes, and weakened structural materials throughout the surrounding area.
Whether you have a wood deck adjacent to your home, a pool deck, or perhaps even a roof deck affording a glorious ocean view, waterproofing is essential for each of these structures, and the team at Thome can provide you with any type of deck waterproofing services you might need, including wood deck coatings, pool deck coatings, and more.
Wood deck coatings help prevent moisture from soaking into the wood and contributing to swelling, cracking, warping, or rot. Pool deck coatings protect surfaces that are frequently exposed to splashing, chemicals, and changing weather while also providing a more comfortable, slip-resistant walking surface. Roof deck waterproofing is especially important because leaks can affect not only the deck but also the walls, ceilings, framing, and living spaces beneath it.
In California, most homes are built on either a slab foundation or a crawlspace foundation. No matter what type of foundation your home rests upon, proper waterproofing is essential. At Thome Waterproofing, we can provide any type of foundation waterproofing you might need.
While comprehensive waterproofing should have been installed during the early phases of construction, this doesn’t always occur, and our team of waterproofing experts can provide you with slab waterproofing, crawlspace waterproofing, or even basement waterproofing if you are one of the rare Southern California homeowners who possess a subterranean structure in your home.
Foundation waterproofing not only protects your home from water damage, but it also improves the air quality and energy efficiency. For instance, when we provide crawlspace encapsulation, we help prevent ground moisture from entering the space, which can reduce humidity, discourage mold growth, and make it easier to maintain a comfortable indoor temperature.
In areas such as Southern California, where droughts, heavy winter rains, and seismic activity are common, retaining walls can be an important protective barrier for many properties. These walls hold back soil on sloped or uneven land, helping prevent the ground from shifting or eroding.
Retaining walls also can help manage water runoff and protect nearby foundations, walkways, landscaping, and other structures. Because soil behind the wall can become saturated during heavy rain, proper drainage and waterproofing are essential. Without them, water pressure can build up and cause cracking, leaking, bulging, or structural movement.

Window & Door Waterproofing
Additionally, it’s crucial to inspect your doors and windows before the heavy winter rains. For instance, wood window frames with peeling paint or dry rot can allow water to seep into your home’s structure. Doors also should be sealed properly along the bottom, with a correctly installed door pan to help prevent water from entering beneath the door.
A Note About Drainage
While proper waterproofing is crucial for any type of property, drainage is equally as important. Many homes and commercial properties in Southern California lack proper drainage systems, which can become a serious concern during periods of heavy or prolonged rain. Even a well-installed waterproofing system may be placed under unnecessary stress when water is allowed to collect against walls, foundations, balconies, or other vulnerable areas.
Gutters, downspouts, and ground drains work together to collect water and move it safely away from the building. Gutters capture rainwater as it flows off the roof, while downspouts carry it toward the ground. From there, properly positioned drains and drainage lines direct the water away from the foundation and toward an appropriate discharge point.
When any part of this system is missing, clogged, damaged, or improperly positioned, water may pool around the property, saturate the soil, and place pressure on foundations and retaining walls. Proper drainage helps reduce standing water, soil erosion, moisture intrusion, and unnecessary wear on the property’s waterproofing systems.
