Have you noticed water sitting around your home after rain or lawn watering? A good drainage system keeps your property dry by moving extra water away from your home, yard, and foundation.
In Los Angeles, this matters a lot because rainwater, stormwater, and irrigation runoff can build up fast, especially on flat lots. When water has nowhere to go, it can damage your home and create unsafe conditions.
Demo Leaders Inc. provides strong, long-lasting drainage solutions designed for your property, giving you steady protection and peace of mind.
A drainage system is a group of parts that collect and move water away so it does not harm your home. This includes systems for wastewater, stormwater, rainwater, and roof runoff. It may use surface drains, subsurface drains, gutter and downspout systems, and storm drains.
These systems mostly work with gravity, but pumps can be added when needed. Every drain line must have the right slope so water keeps moving. When everything is set up correctly, water flows safely to an outlet or disposal point.
Los Angeles homes face many problems when water does not drain the right way. Water can push against your foundation, enter your basement or crawl space, and weaken the base of the home. Many LA yards deal with pooling because the adobe soil absorbs water very slowly.
During strong rain, water may gather on the surface, cause flooding, wash away soil, or create damp areas where mold grows. Wet soil can expand and shrink, which may lead to cracks or structural shifting. Fixing drainage protects your home from surface water, groundwater buildup, and stormwater overload.
Surface drainage systems help move extra water off the top of the ground. These systems may use open ditches, channels, sloped grading, levees, humps and hollows, and grassed waterways. They help guide water away from your home, driveway, or lawn before it can soak in and create problems. Surface water often collects during heavy rain, and these systems help move it to a safer point.
Subsurface systems sit underground and move water through buried pipes. They work well for wet yards and homes with rising groundwater. The pipes, either perforated or solid, rest in a gravel trench and follow a slope of about ¼ inch per foot.
These drains can be placed in low spots, along the home, or around the perimeter. When gravity allows, they direct water to the curb, street, or another safe outlet. This setup gives strong protection against water that builds up below the surface.
Storm drains and rain drains collect surface runoff during storms. These systems may include catch basins, channel drains, pop-up drains, square or round grates, atrium grates, and lawnscape outlets. They help move water quickly before it floods the yard or enters the home. These systems can connect to other drain lines for better flow across the property.
Downspout drainage moves water from the roof away from the foundation. When downspouts dump water too close to the home, it can cause soil issues and leaks. Extensions and buried drainpipes redirect roof water to a safer area. This helps prevent erosion, standing water, and damage to the home’s base.
Homes with crawl spaces or basements often face moisture problems when water gets in. Drainage systems protect the lower parts of the home from cracking, bowing, or flooding. These may include sump pump systems or specialty basement drainage products. These tools help keep the area dry and protect valuable items and building materials from damage.
Exterior waterproofing works with drainage systems to stop water from entering the home. This helps reduce mold, humidity, and air-quality problems. When waterproofing and drainage are used together, the foundation, crawl space, and basement stay dry even during strong rain.
One helpful option is the Flo-Well Storm Water Leaching System. It moves water into the subsoil instead of letting it run across the ground. This lowers runoff, reduces puddles, and allows water to be reused for irrigation. Over time, it helps improve the underground water table in the area.
Some homes may need help with plumbing and drainage. This includes sewer lines, vents, and traps that help wastewater move to a sewer or septic system. These lines need a proper slope to keep water flowing and to stop sewer gas from entering the home.
A drainage system collects water from gutters, downspouts, surface drains, and subsurface lines. The water then moves toward lower points of the property or into a municipal drain. Gravity does most of the work, but some homes need sump pumps or collection pits when water must be lifted.
Different systems work together to handle roof runoff, surface water, and groundwater. When installed correctly, drainage keeps your home safe from water buildup.
A home may need better drainage if water pools in the yard or near the foundation. Rainwater may reach the crawl space or basement. Cracked or shifting foundation footing is another warning sign.
Standing water that stays for weeks can point to deeper issues. Mold, musty smells, and high humidity can come from moisture problems. If downspouts overflow or the yard grading looks uneven, water may not be flowing away correctly. Soil erosion or soft areas in the yard also show poor drainage.
Many homes in Los Angeles deal with broken, clogged, or collapsed drain pipes. Repairing these lines helps water move away from the home again. Some older homes have grading problems or patchwork drains that never worked well.
Fixing damaged downspouts or failed drainage connections can stop water from entering the crawl space or basement. Repairs also help remove stagnant water, which can take weeks to dry and cause more damage. With the right repair work, your home stays protected from flooding, saturation, and foundation issues.

Homes need a good drainage system when water does not drain off the property. Without it, water can harm the base of the home, crack basement walls, and even cause indoor flooding.
Damp areas can lead to mold growth and unhealthy air. Soil may wash away or shift, which affects the stability of the home.
Plumbing drainage also plays a role by keeping wastewater moving and stopping sewer gas from entering the house. Reliable drainage protects the home from serious problems.
