 Trustindex verifies that the original source of the review is Google. Just had a set of french drains and new downspout drains installed and we couldn't be happier with the work. The owner was very responsive and helpful. We called on a Thursday afternoon after seeing some water in our basement and he came right out that evening and got started the very next morning. They did an excellent job cleaning up after themselves every day and even helped me out with a few minor touch ups. Would absolutely recommend them to anyone else needing some work done.

 Trustindex verifies that the original source of the review is Google. They were very responsive and came by and provided a reasonable estimate quickly. They waterproofed my basement (had a mold issue which prompted me to reach out to them) and I haven’t had any issues so far. Worked fast and explained clearly what needed to be done.

 Trustindex verifies that the original source of the review is Google. Vlad and the Basement Expert team did a fantastic job installing a complete perimeter drain and waterproofing system in our unfinished basement. We appreciated that they were timely, clean, clear communicators, and most of all, that they did excellent work. Our project was challenging, but they were ready to tackle everything that came up including plumbing changes and having to trench around a large boulder, without any unexpected costs on our side.

From the start, Vlad’s evaluation of our project was honest and thorough, and they were transparent with pricing and the scope of work. The pricing was competitive and we felt that their team went above and beyond with their excellent workmanship and attention to detail. Throughout the project, they explained what they were doing and consistently made great decisions. For anyone needing a sump pump, french drain, or other basement waterproofing services, I’d recommend Basement Expert without any hesitation!

 Trustindex verifies that the original source of the review is Google. Vlad of Basement Expert Waterproofing recently diagnosed my basement leak issue. He came with scopes and moisture readers, and was able to not only verify the condition of work I had done previously with another company, but suggest what a reasonable fix would be. He came out the day after I called, and while we had planned to do the job the following week, he was able to complete the job the same day when space opened up in his schedule. I can’t believe it. In the midst of rainy season I got a same day fix with a new rock well and diversion system. These guys are honest, professional, timely, and cost effective. Total pleasure working with them, and they will for sure be the first ones I call if ever I need this type of service again. Thanks Vlad and crew.

 Trustindex verifies that the original source of the review is Google. We highly recommend Basement Expert. Being new to the area we talked with a lot of companies about waterproofing and other house projects and we were initially impressed with Basement expert's clear communication and they didn't seem like they were trying to sell us something we didn't need.

After hiring them, the clear communication continued and we found them to have integrity and take pride in their work. They were also very clear and fair about pricing and definitely earned our trust. We can now rest easy when there is heavy rain knowing that their work is protecting our home and the money we have put into our other improvements!

 Trustindex verifies that the original source of the review is Google. They are knowledgeable, showed up consistently, and provided updates when unexpected obstacles came along. We have a tricky foundation at the base of a wet hill with poor access and they built complete foundation and runoff drain systems in less than 2 weeks.

 Trustindex verifies that the original source of the review is Google. I had them add French drains and a channel drain to our basement because water was getting in from the garage and the walls. They did a great job covering the old catch basin in the driveway, adding French drains, and tying our gutter into the new channel drain line. Excellent work, great communication through the entire process, and real integrity. After it was finished, I noticed that the garage door wasn't closing because they had raised the level of concrete. Serhii was out first thing on Monday to fix it, and while he was here he noticed that some of the extra strong concrete they installed in the garage entryway wasn't drying like it was supposed because it's the rainy season. So he had Anatole come out the same day to remove it and install more quick drying concrete. That kind of service and response time is hard to find with contractors.

The only thing I wish that was slightly different about the install is that the dimple board (moisture catching fabric on the walls) came out a bit wavy which will make it look pretty bad if we want to paint over it. So we'll probably put up drywall in the basement to cover it, but sadly that will reduce the amount of usable space. I'm not sure if that issue is even something that other contractors could avoid. And in all other respects, they did a fantastic job and we're very pleased. Hasn't been a big rain to test out the new system, but it sure looks solid. Would happily recommend.

 Trustindex verifies that the original source of the review is Google. We called Basement Expert to come out and take a look at an overflowing gutter drain pipe that was causing water to pool near our foundation during heavy rain. They were very responsive and professional and Vlad and his team were able to come out the next day. When they arrived, they scoped our underground drain pipe and found no issue, but they did note that the gutter itself was not installed correctly and that the adapter from downspout to drain pipe needed replacing. They went to grab supplies and came back right away to fix it. They also didn't charge us for the work because it was a small fix! I was super impressed with their work ethic, attention to detail, and willingness to help us for free. I would recommend anyone to give them a call if you think they could help you out!

French Drain Installation in Marysville for Wet Lots

Comparing systems across the region? The drain installation hub covers our full method; this page focuses on local jobs.

Low, flat yards that stay soaked from fall through spring are the most common problem we see in this part of Snohomish County. Basement Expert handles French drain installation in Marysville for homes and businesses, from a single soggy side yard to a full perimeter system around a foundation.

Below is what each system does, what drives the price, and what to expect when we visit.

French Drain Installation in Marysville, WA explained

Problems a Drain Solves

A properly sloped drain line gives groundwater an easier path than your yard or basement. It helps with:

Standing water: puddles and soft ground that linger days after rain.
Basement seepage: water entering where the wall meets the floor.
Wall pressure: saturated soil pushing on below-grade walls.
Dead lawn: turf and roots drowning in waterlogged soil.

Every drain we build is perforated pipe in washed rock, wrapped in filter fabric so silt doesn’t clog it, and sloped to an outlet you can check.

Outside the Foundation

For most yards, the drain goes in the ground outside. We dig a trench along the wet area or the footing, set pipe on a steady fall, cover it with rock, and route it to a daylight outlet, dry well or approved storm connection. Downspouts stay on their own solid lines.

Inside the Basement

If a deck, driveway or neighbor’s fence blocks outside access, the drain goes under the basement slab along the walls instead. Water collects in the channel and flows to a sump, which pumps it out and away from the house.

Business and Multi-Unit Sites

Commercial lots move more water and have more in the way: paving, utilities, landscaping islands. Our team:

Maps the site and where runoff concentrates.
Estimates the flow the system has to handle.
Lays out pipe sizes and outlets on a drawing before digging.

Protecting Your Yard During the Work

Around a home, the goal is a drain that works without leaving a mess. At the first visit we walk the yard with you, mark utilities and plantings, and plan the trench route to avoid what you want kept.

What Does Drain Installation Cost Here?

The average cost to install a drain line in Marysville ranges from $50 to $250 per linear foot. Your written estimate is free and based on what we find on site.

What moves the number:

Total length of drain needed.
Trench depth and digging conditions.
How much water the site collects in heavy rain.
Whether water is already getting into the basement.
Distance to a workable outlet.

Common Questions From Local Homeowners

What's the price range for a drain here?

The average cost to install a drain line in Marysville ranges from $50 to $250 per linear foot. However, the final price depends on factors like the total land area, the volume of work, and the specific water issues on your property. We provide a free, individualized estimate for every customer to give you an accurate price.

What signs mean a yard needs drainage?

Puddles that sit for days, soggy turf near the house, a musty basement or a damp line where the wall meets the floor. Any of these after a few days of rain is worth an inspection.

Inside or outside: which drain do I need?

An outside drain stops water in the soil before it reaches the house and is the first choice when there’s room to dig. An inside drain handles water that’s already reaching the basement when the outside is blocked by hardscape or tight property lines.

Can you drain a commercial lot or parking area?

Yes. We map the site, estimate the water it has to handle and lay out the system on a drawing before any work starts.

What happens on the first site visit?

We walk the property with you, look at where water collects and where it could go, check the basement if there is one, and then send a written scope and estimate.
