About this company
Dansel Restoration operates out of Fremont and San Jose, serving the South Bay and wider Bay Area as a full-service restoration company. They handle mold remediation alongside water damage, fire damage, sewage cleanup, and reconstruction — making them a one-stop shop rather than a mold-only outfit. Daniel Arzate runs the company and appears to manage projects directly.
On the mold side, they list specific equipment on their website: HEPA vacuums, air scrubbers, negative air pressure units, antifungal biocide treatments, cold mist air fogging, and dry icing. They also do in-house mold inspection with lab analysis, sending samples to a third-party lab before starting remediation. The reconstruction capability means they can tear out mold-damaged drywall and flooring and rebuild it without subcontracting.
Dansel holds IICRC firm certification (#70044891) and a California contractor's license (CSLB #1105699). They advertise 24/7 emergency response and free initial assessments. The company assists with insurance claims and provides inspection reports that can support filings.
A 4.9-star rating across 63 Google reviews is unusually high, especially for a restoration company where project complexity often generates friction. Multiple reviewers — including landlords, commercial clients, and homeowners — describe the same traits: fast response times, honest scoping (several note Daniel or Fernando told them they did not need expensive work), and willingness to fix issues without argument.
Services
Service area
Dansel Restoration operates from two locations: Fremont (43177 Osgood Rd) and San Jose (1900 Camden Ave). They list 20 service cities across Alameda, Santa Clara, and San Mateo counties, including Fremont, San Jose, Oakland, Hayward, Palo Alto, Sunnyvale, Santa Clara, Milpitas, San Mateo, and Redwood City. Reviews confirm work in San Carlos and Santa Cruz, suggesting they travel beyond their listed area for some projects.
Review consensus
Fernando Ponce appears in the most reviews, praised repeatedly for clear communication, honest assessments, and responsive project management. Multiple reviewers specifically note that Fernando or Daniel told them they did not need expensive services when simpler solutions would work. Daniel Arzate draws praise for hands-on involvement, punctuality, and attention to detail on reconstruction projects. Reviewers consistently highlight fast response times — several describe same-day inspections and next-day work starts. Landlords and property managers mention quick mold testing turnarounds. The crew's habit of protecting floors and furniture with plastic and paper before starting work comes up in multiple reviews.
1 found across 63 total reviews at 4.9★. The single recent negative is a 3-star review describing a bathroom restoration after a leak. The reviewer reports that subfloor thickness, shower installation, and floor transitions were all done incorrectly the first time. Staff turnover during the project was high — one person quit and two were fired. The project stretched from an estimated 3-4 weeks to over four months. The reviewer credits Dansel for ultimately redoing the work to meet expectations but notes the company initially pushed back on rework requests before agreeing. The owner's response provides context: the homeowner's tile selection required subfloor adjustments, work was limited to hours when the homeowner was present, and an extended trip further delayed the timeline. The owner also states the company does not hire day laborers, contradicting the reviewer's impression.
The owner response to the sole negative review is detailed and personalized — not a template. It addresses specific claims point by point, offers factual corrections, and acknowledges the project's challenges. This is notable because many restoration companies use generic responses. The response quality suggests active reputation management with genuine engagement rather than copy-paste deflection.
Fernando Ponce (project manager — consistently praised for communication, honesty, and responsiveness across 10+ reviews). Daniel Arzate (owner/project manager — praised for punctuality, attention to detail, and honest scoping). Selena (coordinator — praised for patience and helpfulness). Jose (crew — mentioned positively). Fabrico (crew — praised for restoration work quality). Sergio (crew — praised for restoration work quality). Rohit (crew — mentioned positively). Danny (likely Daniel Arzate — praised for immediate assessment and reasonable recommendations).
Ask for Fernando or Daniel as your project manager — both have strong track records across dozens of reviews. If your project involves reconstruction (not just mold cleanup), ask upfront how they handle crew continuity and what happens if work needs to be redone. The 3-star review's experience with rework and delays is a one-off in 63 reviews, but it maps to a real risk with any reconstruction-heavy project.
Keep in mind
- Dansel does both mold testing and mold remediation. This creates a financial incentive to find problems they then get paid to fix. Consider getting an independent mold test before committing to remediation work.
- The one recent negative review describes a bathroom restoration that ballooned from 3-4 weeks to over 4 months, with multiple items done incorrectly the first time and frequent crew changes. The owner's response disputes some details — citing the homeowner's travel and schedule constraints as contributing factors — but the reviewer's account of rework and staff turnover is specific enough to take seriously.
- Their service area covers 20+ cities across Alameda, Santa Clara, and San Mateo counties. Response times and crew availability may vary for locations farther from their Fremont and San Jose offices.
- Most of their reviews describe water damage restoration and reconstruction work. Mold-specific reviews exist but are a smaller portion of the total, so the 4.9-star rating reflects the full range of their services.
