 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 Everett, WA and Snohomish county

Covering the whole Seattle metro? Our main drain installation page explains the method. This page covers local jobs.

Basement Expert handles French drain installation in Everett for yards that hold water and basements that seep at the floor joint. The drain itself is simple: perforated pipe in washed gravel, wrapped in filter fabric and sloped to a real outlet such as a daylight point, a catch basin or a sump. The hard part is the plan, so every job starts with an inspection that maps where the water comes from before we size the run.

What We Check Before We Dig

Much of the north end sits on dense glacial till. Rain soaks the top few feet, hits the hardpan and then moves sideways toward the house instead of draining down. On the walk-through we look at:

Where water stands after a storm and how long it stays.
Downspout layout. Roof water stays in its own solid pipe and never goes into the perforated line.
Grade along the foundation and how far we can carry water to discharge.
Basement clues: white efflorescence, a damp cove joint, or water at the wall-to-floor seam.

Yard and Footing Drains Outside the House

Outside, we trench along the wet area or the footing, line the trench with fabric, bed the pipe in washed rock at a steady fall and backfill so surface water can reach the gravel. On a footing run the pipe sits beside the footing, not on top of it, so it picks up water before pressure builds against the wall.

We restore the trench line, but plan on some lawn and bed repair where the excavator works.

Interior Perimeter Drain When Digging Isn’t Possible

When a deck, driveway or the property line blocks the outside, we cut the slab along the inside of the wall, set a perimeter pipe next to the footing and run it to a sump basin. A dimple membrane goes on the wall so seepage drops into the channel instead of spreading across the floor.

Larger Lots and Commercial Sites

Big lots and commercial buildings need a flow estimate before pipe size and outlets are chosen. We measure roof area and paving that sheds water toward the problem spot, then put the run, pipe size and discharge points on a drawing before anyone starts digging.

What Does Drain Installation Cost?

The average cost to install a drain line in Everett ranges from $50 to $250 per linear foot, but prices are always calculated on an individual estimate, which is provided to each customer free of charge. What moves the number:

Length of the run and depth to the footing.
How far the water has to travel to a legal outlet.
Inside versus outside work, and whether a sump is needed.
Decks, pavers or plantings that have to come out and go back.

Questions We Hear on Site Visits

Short answers from the crew. The inspection settles the details for your property.

Do these drains work in tight clay and till soil?

They do when the pipe has somewhere to send the water. On tight soil we use more washed rock, a fabric that won’t clog, and a clear outlet. A drain with no outlet is just a buried bathtub.

Is a drain worth it if the basement only leaks in big storms?

Often, yes. Storm-only leaks usually mean water builds against the footing for a few hours at a time. Catching it with a footing or interior drain costs less than repeated cleanups, but we confirm the source before recommending one.

What will my drain cost?

The cost of installation in our company ranges from $50 to $250 per linear foot, but prices are always calculated on an individual estimate, which is provided to each customer free of charge.

Why does water get into the basement in the first place?

Rain and snowmelt soak the soil around the house and push against the basement walls and footing. That pressure forces water through cracks, tie holes and the joint where the wall meets the slab. A drain relieves the pressure by giving the water an easier path out.

How long does the system last?

A drain built with fabric, washed rock and proper slope keeps working for many years. We add cleanouts so the line can be flushed instead of dug up, and clean gutters keep debris out of the system.
