The service
Drain Installation
Robles installs new drain systems throughout the Portland Metro area for homeowners dealing with a yard that won't drain, a remodel that needs new plumbing, or new construction that needs a drain system from the ground up.
An installation is a different job than a repair. There's no existing line to diagnose, but there is a right way and a wrong way to route, size, and slope a new drain so it actually works for the life of the system. Robles plans every installation around how water actually moves across your property, not just the shortest distance between two points.
Licensed Contractor Work
Robles carries the contractor license new drain installation in Oregon and Washington requires.
Built for Pacific Northwest Rain
Systems are sized and sloped to handle the volume of rain Portland actually gets, not a minimum-code guess.
A new drain installed wrong is worse than no drain at all, since it gives a false sense that the water problem is solved. Robles installs it right the first time.

Residential
Residential Drain Installation in the Portland Metro Area
Robles installs residential drain systems across the Portland Metro area for new construction, additions, ADUs, and remodels that need new plumbing from scratch.
Sized, sloped, and connected correctly
A new bathroom, a kitchen remodel, or an ADU build all need drain lines sized, sloped, and connected correctly to the existing system or the public sewer. Robles works directly with homeowners and, where needed, coordinates with the general contractor on the project so the drain work lines up with the rest of the build instead of becoming an afterthought.
Yard drainage
Yard, Storm, and Area Drain Installation in the Portland/Vancouver Area
Robles installs yard, storm, and area drainage systems, including French drains, for properties throughout the Portland/Vancouver area that deal with standing water, a soggy yard, or water pooling near the foundation.
A French drain is a perforated pipe surrounded by gravel that collects water and carries it to a discharge point, reducing pressure and standing water in the yard before it becomes a bigger problem. Robles installs exterior yard and area drains based on how water actually moves across your property, factoring in slope, soil type, and where the water needs to go once it's collected.
Standing water in the yard or driveway after normal rainfall
Water pooling near the foundation instead of draining away
A soggy or spongy patch of lawn that never fully dries out
Storm drains or area drains that are clogged, undersized, or missing entirely
Water runoff from a neighboring property collecting on your lot
Landscaping or hardscaping projects that need drainage planned in from the start
The process
Our Installation Process
Robles follows the same process on every drain installation across the Portland Metro area, whether it's a single yard drain or a full residential system.
-
1
Site Assessment
A technician evaluates the property, identifies where water is coming from and where it needs to go, and plans the route and slope of the new system.
-
2
Permitting
Robles pulls the required permits for the scope of the work before any digging starts.
-
3
Installation
The system gets installed to the planned route, using materials sized correctly for the volume of water the property actually sees.
-
4
Inspection and Sign-Off
The completed work is inspected and signed off, so the installation is documented and code compliant, not just buried and left.
Permits & code
Permitting and Code Compliance
New drain installation in the Portland Metro area requires permits, and Robles manages that process as part of the job rather than leaving it for the homeowner to sort out.
Why it matters
Depending on the scope, a new drain installation may require a plumbing permit, and work that ties into the public storm or sanitary system may require additional city review.
Skipping the permit process can create real problems later, from failed inspections during a home sale to the cost of redoing work that wasn't approved the first time. Robles pulls the correct permits, schedules the required inspections, and makes sure the finished system is signed off correctly.
Common questions
Frequently Asked Questions About Drain Installation
Do I need a permit for a new drain installation in Portland?
In most cases, yes, especially for work that ties into the public storm or sanitary system. Robles manages the permit process as part of the job, so the installation is documented and inspected correctly rather than left unpermitted, which can cause problems later during a home sale or an unrelated inspection.
What is a French drain and do I need one?
A French drain is a perforated pipe surrounded by gravel that collects water and carries it to a discharge point away from your home. It's a common solution for a yard that holds standing water or water pooling near the foundation. Robles evaluates the property first to confirm a French drain is actually the right fix rather than assuming it by default.
How long does a drain installation take?
A single yard or area drain can often be installed in a day. A larger residential system tied to new construction or a remodel takes longer, especially once permitting and inspection timing are factored in. Robles will give you a realistic timeline once the scope of the work is confirmed.
Can you install drainage for a new ADU or addition?
Yes. Robles installs drain systems for ADUs, additions, and remodels throughout the Portland Metro area, sized and routed to tie into the existing system or the public sewer correctly. Robles can also coordinate with your general contractor if the drain work is part of a larger build.
Why does my yard have standing water after it rains?
Standing water usually means the ground isn't able to absorb or drain water fast enough, often due to soil type, grading, or a missing drainage system entirely. Robles assesses how water moves across the property before recommending a fix, since the right solution depends on where the water is actually coming from.
Do you install storm drains and area drains, or just yard drains?
Robles installs all three: yard drains, area drains, and storm drain connections, depending on what the property needs. Many properties end up needing a combination, especially where multiple problem areas are collecting water separately.
What happens if a drain is installed without a permit?
Unpermitted work can create real problems later, including failed inspections during a home sale or the cost of redoing work that was never approved. Robles pulls the correct permits on every installation so this isn't a risk you're carrying on the property.
Will installing a drain solve water pooling near my foundation?
In many cases, yes, when the drain is planned and sloped correctly to intercept the water before it reaches the foundation. Robles evaluates the specific cause of the pooling first, since the fix depends on where the water is coming from and how it's moving across the property.
Do you offer any guarantee on new drain installation work?
Yes. Drain installation work from Robles is backed by the company's service guarantee, and every installation is permitted and inspected as part of the job.
