Ramon and Fidel were great and very responsive. They installed a French drain and when we realized the water problem was worse than I expected they were able to pivot very quickly. All of the guys working were very kind and friendly. They also built a beautiful fence for me that looks great!...

Bernardo and his team were a joy to work with. They were incredibly fast, punctual, and friendly. They installed a French drain for our super muddy backyard. Bernardo spent time explaining the process, and we would definitely hire his team again!

The French drain works very well. We had a small pond in our back yard during the winter rain, and now it drains perfectly. The grass looks beautiful. Their team worked very well together and took care in protecting cables, and modified the sprinkler system as needed. They did a great job. I...

I found water in my crawlspace for the first time in the 15 years I had lived in my house. Kevin spent over an hour looking at crawlspace, digging outside to find the origin of the french drain that had been installed 15 years earlier and advising my as to what to do. In the end he...

"Israel and his team were great to work with and I am really happy with both of the projects they competed for me. They replaced an old, failing retaining wall with a beautiful stone retaining wall with a French drain behind it. I showed Israel pictures of what I wanted it to look like and his team did an amazing job making my vision a reality. They were careful with my existing plants and landscaping and went above and beyond by moving and repotting a shrub that I was unable to move by myself before the work began. They also replaced parts of my backyard that had been removed by neighbors and built a beautiful new fence and gate out of cedar. They did an amazing job matching the style of the existing fence and my yard looks so much better now. I am so happy with everything and I would work with GI Landscaping again anytime!"

Forest Landscape Inc
Forest Landscape Inc
Forest Landscape, Inc is proud to present our customs landscapes for your home.We are a landscape company that emphasizes more then your typical, run-of-the mill projects that take up space within your neighborhood.
"We recently expanded a deck, added a patio cover, and are putting a hot tub underneath this second floor deck. There was a concrete patio below the existing deck and we wanted to match that, w/ reinforcement for a hot tub. We got a couple bids for the job. Danny was the estimator that came out for Forest and he seemed knowledgeable and was punctual and professional. It was not the cheapest bid, but the company is much more well established than a couple others we consulted so I put more trust in their work. Rigo is the guy we needed to work with on scheduling etc. for concrete work. This was a little rocky at first, but that had a lot to do with us needing to postpone the start till our deck was done, but then also work around a vacation we'd be taking, and make sure the concrete had enough time to cure before our hot tub is dropped. Despite a slight language barrier, we worked it out and even managed to get it done ahead of when we originally scheduled it. Punctuality is impressive with these guys. For 3 days they were waiting outside our house to start at 7:30am precisely. They had to remove a portion of fence and work around some foliage for access. They ended up encountering an unexpected drainage tube of some kind while digging and made sure to create an access point for us if it's ever needed in the future. The concrete looks great and matches our old patio so well, it's hard to tell they weren't poured together. Danny and I (and later Rigo) discussed treating the old concrete to help the matching. At the end of the work they did a great job of cleaning up the area and returning everything to normal. Rigo also helped us by showing us how to remove the fence portion for when our hot tub is delivered and left the top cap off because he said we'd really struggle to get it off if they put it back. I'm happy with the work, communication, and cleanup and trust if there are any problems I will be able to get them resolved. If we have further landscape needs in the future I will def be calling Forest for a bid."

"We hired Western Paver Design to redo our backyard. I was referred them by two different people in my neighborhood. I obtained multiple estimates but decided to go with WPD based on the personal recommendations as well as Joe being so friendly and knowledgeable during the estimate. He answered all of my questions, provided his expertise and input on what would work or not, and gave a fair and competitive price. Joe created a wonderful plan for our backyard based on what we wanted. He took our “wants” and ran with it. Darwin led his team with Marteen and Modesto to complete the plan and make our backyard our dream backyard. They were incredible to work with. They came and removed all of the sod that was already there. (It was installed incorrectly and looked terrible) the raised the backyard and leveled it all out and built a retaining wall around the whole yard. They installed a large paver patio (roughly 13x18) and then next to that a large turf are, about the same size. Along the house they built a small deck area to be level with the turf and against the house. This was nice so there was no large drop off area, being a hazard for the kids. On the other side of the retaining wall they built me two large raised garden beds As well. I cannot rave enough about Darwin, Marteen, and Modesto, and Joe! They were a pleasure to work with! They were professional and friendly and worked so hard each day they were here. They transformed our yard into exactly what we wanted-a large area for entertaining and BBQing, a nice turf area for the kids, and garden beds for me to grow vegetables! The end result is everything we could have imagined!"

FAQs for french drain service projects in Cornelius, OR
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.
