Best for
- Walnut Creek and central Contra Costa County homeowners who need water damage cleanup and mold work handled by a single company.

- Situations where the plumbing problem that caused the water damage still needs to be fixed before remediation can start.

About this company
Roto-Rooter in Walnut Creek is a franchise location of the national plumbing and water damage company, headquartered at 1130 N Broadway. Their primary draw for mold work is the integration with their plumbing and water damage teams: they can fix the pipe that caused the leak, extract the water, dry the structure, and handle mold remediation without bringing in a second contractor. They hold IICRC training for their water damage technicians and carry CA Contractor License #806952.
The mold-specific work here is secondary to their core identity as a plumbing and water damage restoration company. Their mold remediation page describes HEPA filtration, air scrubbers, dehumidification, and antimicrobial treatment, along with AMRT-trained crews. The real differentiator is the single-source model: plumbing diagnosis and repair happen alongside the restoration work, which eliminates the wait for a third-party plumber that standalone restoration companies face.
Roto-Rooter has operated since 1935 nationally. The Walnut Creek location is managed by Bill Ervolina and covers Contra Costa, Alameda, and San Joaquin counties. They run 24/7, 365 days a year, with no overtime charges for nights, weekends, or holidays. Trucks arrive stocked with parts and extraction equipment for single-visit resolution.
4.9 stars across 297 Google reviews is unusually high for a franchise operation at this volume. Most of the positive reviews name individual technicians by name and describe repeat use, which points to a stable local workforce rather than rotating contract labor.

Review consensus
Sal is the standout name. At least 15 reviews in the sample mention him by name for drain cleaning, leak repair, and sink work. Reviewers describe him as communicative, persistent with difficult jobs, and organized. Rey draws similar praise for after-hours responsiveness, including Christmas Eve and late-night faucet calls. James, a field supervisor, earned a mention for following up on a potential pipe issue and explaining future risks. Lejla was praised for coordinating a condo repair around a building water shutoff. Will earned a callout for spending three hours on a stubborn problem and not giving up. Several reviewers note same-day or next-day availability and single-visit completion as key strengths.
3 found across 297 total reviews at 4.9★. Charles Luecker booked an appointment for outdoor drain cleaning, then got a callback 90 minutes later canceling because the location "didn't clean out yard drains." He had used Roto-Rooter at other locations without issue. Bill Schneider reported an incomplete drain repair: after the technician left, water backed up into the bathroom, and the technician wanted an extra $100 for a guarantee. Nick Zarcone paid $500 for a repair that failed the next morning, then says Roto-Rooter missed three follow-up appointments until the warranty expired and tried to charge another $500. The Zarcone complaint is the most concerning: a failed repair, missed callbacks, and an expired warranty looks like a systemic follow-through failure, not a one-off.
The negative reviews all describe problems that happen after the initial technician visit: a canceled appointment, a repair that failed overnight, warranty follow-ups that never materialized. The technician-level work draws almost no complaints. This is a classic franchise pattern where the field team is strong but the dispatch and follow-up systems create gaps. The owner response pattern reinforces this: every negative gets the same templated redirect to Pat Swanson, a Customer Satisfaction Manager. None of the responses address the specific complaint, which reads more like reputation management than problem-solving.

Ask for Sal or Rey if your job involves drain work or after-hours plumbing repair. For mold-specific work, confirm in advance exactly what this location handles in-house and get the scope of work in writing before signing. If you need warranty follow-up, document the commitment at time of service and follow up proactively rather than waiting for their dispatch to call you back.
Keep in mind
- Roto-Rooter does both mold testing and mold remediation. That means the same company telling you that you have a mold problem is also the company selling you the fix. Consider getting an independent mold assessment before committing to their remediation scope.
- Three 1-star reviews in the past 18 months describe scheduling problems: a canceled appointment after booking, missed warranty follow-up visits, and an incomplete repair followed by an upsell. The pattern points to dispatch and follow-through gaps, not technician quality.
- Pricing runs higher than smaller local contractors. One 5-star reviewer noted they are "certainly a higher price than other contractors" but felt the experience justified it. Get the upfront estimate in writing before work starts.
- Their mold remediation page is a national template, not Walnut Creek-specific. Confirm what mold services this particular location actually performs in-house versus subcontracts.
- Owner responses to all negative reviews follow the same template: apologize and redirect to Pat Swanson's email. None engage with the specific complaint publicly, which makes it hard to know how these issues were resolved.
