What this listing says
Redmond and Greater Seattle homeowners dealing with basement water intrusion and secondary mold growth who want a single contractor handling waterproofing, drainage, and mold remediation under one lifetime transferable warranty.
Best for
- Seattle Eastside homeowners (Redmond, Bellevue, Kirkland) with basement flooding during the rainy season who need both waterproofing and mold work handled by one crew.
- Buyers who want a permanent drainage solution backed by a lifetime transferable warranty rather than a short-term patch.
- Homeowners with older basements experiencing water seepage through foundation walls or floor slabs, where the root cause needs diagnosis before remediation.
- Anyone dealing with mold discovered after a water intrusion event who wants testing and remediation from the same contractor without coordinating multiple companies.
About this company
Wet Basement Services is a family-owned restoration company based in Redmond, WA, serving the Greater Seattle area. Owner Jerzy Radka founded the company after his wife's cancer diagnosis was traced to mold exposure in the home where she grew up. That origin story shapes how the company operates: they treat waterproofing and mold control as a single problem, not two separate service calls.
The standout offering is their proprietary Extreme Water Abandonment (EWA) system, which combines interior French drains along foundation footings, wall membranes, and sump pumps into one integrated waterproofing solution. They also run drainage camera scoping to diagnose water intrusion sources before proposing fixes. On the mold side, they handle testing (with samples sent to a lab for identification) and remediation, using HEPA shop vacuums, air scrubbers, and high-velocity fans for dust and air quality control during work.
Jerzy holds a Master's in Forestry and a postgraduate degree in Environmental Protection, both from 1983. He runs estimates and oversees projects. John serves as project manager and lead on-site, handling day-to-day communication and crew supervision. The company won the Seattle Times People's Choice award for Best Restoration Company in the Pacific Northwest in 2025 and holds IICRC certification.
4.8 stars across 57 Google reviews is a strong rating, especially with zero negative reviews in the last 18 months. Multiple reviewers mention returning years later for additional projects, which suggests the work holds up over time.
Services
Service area
Headquartered in Redmond, WA. Serves the Greater Seattle area including Redmond, Bellevue, Kirkland, Renton, Bothell, Issaquah, Sammamish, Kenmore, Lake Forest Park, Shoreline, Edmonds, Lynnwood, Everett, Mountlake Terrace, Auburn, Kent, Federal Way, Tukwila, Burien, Snohomish, Duvall, and Carnation. That is a wide footprint for a small crew, so confirm scheduling for locations far from Redmond.
Review consensus
John draws the most mentions across reviews. Reviewers credit him with same-day site visits, clear explanations of water intrusion causes, daily progress updates with photos, and clean job sites. Jerzy is praised for detailed estimates, follow-up visits after project completion, and taking time to explain long-term moisture prevention strategies. Multiple reviewers describe lasting results: Brent Thomas reported his 2022 fix held through heavy rain seasons, Catherine Henson confirmed all systems from a June 2022 install were still working years later, and Brent Thomas (Wingfan191) noted WBS returned for a follow-up adjustment at no charge when his high water table required a pump upgrade. Reviewers consistently note fair pricing relative to competitors and willingness to handle unexpected complications without inflating the bill.
0 found across 57 total reviews at 4.8★. No negative reviews (1-3 star) found in the last 18 months. The single 4-star review (Lisa Carlson, July 2023) noted the work was done on time and as expected, with the only reservation being she wanted to wait for rainy season to fully confirm results.
This is a two-person leadership operation: Jerzy handles sales, estimates, and quality oversight while John runs on-site project management and crew work. Several reviewers mention getting estimates from Jerzy and then working with John during the actual project. That consistent handoff, with both named individuals staying involved, likely explains the high satisfaction rate. Repeat customers (Kenneth Tun used them twice over 8 years, Mark Weisman across multiple houses over 10 years) suggest the work holds up long enough to earn return business.
Jerzy Radka (owner, estimator — consistently positive). John (project manager, crew lead — consistently positive).
This is a small, owner-operated company where you will likely deal directly with Jerzy and John. Ask Jerzy during the estimate whether you actually need the full EWA system or a targeted fix. Get an independent mold test before agreeing to remediation work, since they handle both testing and remediation. If your project is at the far edges of their service area, confirm response times and crew availability before scheduling.
Keep in mind
- They do both mold testing and mold remediation. This creates a conflict of interest: the company diagnosing your mold problem also profits from fixing it. Consider getting an independent mold test to confirm their findings before committing to remediation work.
- Their service area list covers 20+ cities from Everett to Federal Way to Auburn. A company based in Redmond serving that wide a geography may have longer response times at the edges.
- The website emphasizes their proprietary EWA system heavily. Ask whether your situation actually requires the full system or whether a simpler fix (repointing, regrading, gutter correction) would solve the problem at lower cost.
- With 57 reviews and no recent negatives, there is limited complaint data to assess risk. The company's track record looks clean, but a small review count means patterns are harder to detect.
