We used them to help with a rock well for our sump pump and they were quick, affordable, very communicative, and professional! I would use them again in the future if I needed them!

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.

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.

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!

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.

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!

Very responsive and professional! They came out and fixed my foundation crack the very next day after giving a competitive price.

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.

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.

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!

On Eastside hillsides and glacial till, settlement and wall movement show up as stair-step cracking, racked doors, and floors that lose level after wet seasons. Basement Expert starts with measurements—crack behavior, moisture paths, and bearing—so the scope matches the failure mode before any pier or strap goes in. Call (206) 388-7867 to schedule an inspection.

Basement Expert handles foundation repair in Bellevue when doors rack, floors slope, or stair-step cracks open after wet seasons on Eastside glacial till and hillside fill. We measure what is moving, separate cosmetic cracking from structural drift, and only then recommend piers, wall reinforcement, or injection—not a one-size patch.

Licensed ARTBRL*812B8. Inspection-first. Call (206) 388-7867 to schedule an on-site evaluation.

What we measure on Bellevue foundations

Eastside soils range from dense till under older plats to softer fill along lake-facing slopes and newer cuts near Factoria and Crossroads corridors. Rain loads change seasonal moisture under footings. On the visit we document crack width and orientation, check for ongoing movement, look at drainage paths that undermine bearing, and note whether interior finish is hiding an exterior problem.

  • Vertical vs stair-step vs horizontal patterns and whether they are active
  • Door/window racking and floor slope relative to bearing walls
  • Evidence of washout, poor grading, or failed downspout discharge at the footing

Stabilization options (matched to the failure mode)

Once the mechanism is clear, scopes stay narrow—and that is how we keep these projects honest instead of selling a menu:

  • Underpinning / push or helical piers when settlement is localized and load needs a deeper bearing stratum
  • Wall reinforcement (straps or anchors matched to wall type) for inward bow without full excavation
  • Crack injection for sealed, non-structural or stabilized cracks after movement is addressed
  • Exterior excavation and footing work when the failure is outside the slab and interior access cannot reach it

If the main risk is water entry rather than structural movement, we hand off to our basement waterproofing and foundation waterproofing pages instead of forcing a structural scope.

Interior vs exterior approach

Interior work is often enough for crack sealing, composite strap reinforcement, and many pier installs from the basement side. We shift outside when the crack is blocked by mechanicals, the footing itself needs exposure, or grading and drainage must be corrected with the structural fix. You get a written scope that says which side we open and why—not a vague “full package.”

Residential and light commercial

Most calls here are single-family and townhome foundations: crack mapping, pier layout, and wall bracing with clear access plans. Light commercial and HOA buildings get the same measurement-first sequence, with logistics for occupied spaces and phased work when needed.

How the job runs

  1. On-site inspection and photo documentation
  2. Written options with what each fix does—and what it does not claim
  3. Repair with cleanup and as-built notes for your records

Same-day cosmetic crack fills are not the goal. Durable repair follows diagnosis. Questions mid-scope? Call (206) 388-7867.

Related structural paths

Depth reading: Seller prep when movement shows before listing — document, disclose, then decide on repair scope.

If movement is active—or buyers, insurers, or a remodel will scrutinize the structure—documented repair usually costs less than deferred damage plus disclosure risk. Stable hairline shrinkage is different; we say so when monitoring is enough.
“Permanent” means the cause is addressed (bearing, wall restraint, water undermining), not that concrete never shows another hairline. We design against the measured mechanism and document scope limits.
Active settlement and bowing tend to widen finishes, rack openings, and raise repair complexity. Cosmetic fills over live movement fail and hide the trend. Early measurement is cheaper than late excavation.
Ranges depend on access, pier count, wall length, and whether exterior excavation is required. Limited crack or injection work often starts in the mid four figures; multi-pier or excavated wall jobs climb into five figures. We quote after inspection—not from a phone photo. Figures here are not bids.
Surface sealers on inactive hairlines are sometimes DIY. Piering, wall bracing, and anything tied to bearing or lateral earth pressure needs the right hardware and judgment. Mis-installed straps or piers can mask movement without stopping it.
