We used PowerHouse Gutters to upgrade our old, overwhelmed roof gutters and downspouts from the original 4â to 6â , added 2 new French Drains to replace the old severely clogged ones and added gutter guards to help cope with Douglas fir tree debris. Both John and Aaron were great to work...
- Kathryn R.
I can’t say enough good things about our experience with Aden Landscaping. We had our small patio replaced and expanded with pavers last fall. Alex and his team regraded the patio and replaced a French drain. They did an amazing job. It looks fabulous and we had zero drainage problems over...
- Polly D.
This is the second time we have used GHP. Both were small drain jobs, but we were very pleased. They were prompt and efficient. Will call them for any other problem.
- Cheryl N.
They had to dig up the old outdoor drainage and put in new. The had to create two French drains and 4 clean-outs. They did a wonderful job. They cleaned up after every day and I am very very happy with their work. I refer them to all my family and friends who need help with water issues.
- Glenn H.
The drain now works great instead of water from the downspouts spilling onto the ground (and neighbors property).
- Susanna C.
Got clear explanation of what is covered with the deal, which is all we needed. Cleared a slow side drain. Took video of the main drain connection to the city main sewer line, which looked fine. Did not see pipe breakage so all is well.
- Jerry A.
Like I said great job in getting drain repaired. Could not ask for anything more.!

"This review is long overdue in my praise of Washington Energy Services for their customer service, pricing and workmanship ! My first interaction was in 1999 when they installed windows throughout my house. They are still in excellent condition. I might note I called them over 20 years later to inquire on how I could repair a broken slider and they sent someone right out, charging a very nominal amount to repair it. In 2020, I needed to replace my hot water tank, and the extremely knowledgeable Christy presented several options, answering my many questions. I settled on one with a booster that seemed to best fit my needs. Finally, in December 2023, I purchased a new gas furnace from WES. I had a minor issue with a fan switch and they responded quickly to rectify the situation. Within the past two months, I seemed to be having an issue with my thermostat (something they had not installed), and the manager, Greg, came out twice with his crew to explore the problem. Today they installed a new thermostat FREE OF CHARGE! Their excellent response and customer service is beyond any company I have hired. And I particularly love that they are family owned and have been around for decades. Their employees seem to be there for the long haul, which speaks highly of the owner. I refer all my friends and family and I won't go anywhere else for services that they offer. Many thanks to the staff I have interacted with over the past 25 years!"

FAQs for french drain service projects in Union, WA
Landscapers typically charge $25 to $50 per person per hour, which equals around $50 to $100 per hour for a two-person crew. These rates can vary depending on your location, the size of staff needed for the job, and overall job type. For example, a larger crew will be needed for structural additions and hardscaping versus planting flowers.
When it comes to landscapers, licensing laws vary. Landscaping architects are required to be licensed in all 50 states, whereas traditional landscaping contractors are not typically required to hold a certification. You’ll likely be working with a landscaping contractor for most residential projects. If you are redesigning your whole yard or adding in hardscape features, you will work with a landscaping architect at some point during the project. Be sure to check our state licensing tool to review the local landscaper guidelines.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The cost to install a drain pipe is $600 on average, but the total can range between $150 and $2,000. Some cost factors that influence your project price include the type of drain, the area’s accessibility, the proximity of existing drain lines, and whether you’re installing a new drain or replacing an old one. Replacing the p-trap or s-trap under a single fixture will usually cost around $150, while replacing a main drain pipe can cost well over $2,000.
Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations.

We highly recommend leaving the work of replacing drain pipes to a professional plumber. Drain pipes are a key part of your plumbing system, and making mistakes during the installation or even using the wrong size pipes for your specific fixture can lead to an elevated risk of leaks and clogs. Additionally, drain pipes prevent harmful sewer gas from entering your home, so hiring a professional plumber is essential to keeping the risk of leaks and clogs low and avoid reducing your indoor air quality.
