What this listing says
San Jose and South Bay homeowners dealing with water damage that has led to mold, who want a single contractor to handle remediation and reconstruction under one roof.
Best for
- San Jose and South Bay homeowners with water damage that has led to mold growth, who want one company to handle the full scope from drying through reconstruction.
- Property owners who need mold inspection, lab testing, and remediation handled by a single contractor without coordinating multiple vendors.
- Apartment building owners and commercial property managers in the Fremont-to-San Jose corridor who need a restoration company with insurance claim experience.
- Homeowners who have discovered mold in hard-to-reach areas like crawl spaces, attics, or behind walls, where containment and negative air pressure equipment matter.
About this company
Dansel Restoration is a San Jose-based restoration company that handles the full arc from water damage through mold remediation and reconstruction. They operate out of two locations — a main office on Camden Ave in San Jose and a second site on Osgood Rd in Fremont — covering Silicon Valley and the broader Bay Area.
What stands out is their equipment list for mold work: HEPA vacuums, air scrubbers, negative air pressure units, cold mist air fogging, dry icing, and antifungal biocide treatments. They also do their own mold inspections in-house, collecting samples and sending them to a lab before starting remediation. They handle plumbing and lead removal as well, which is unusual for a restoration company this size.
The company holds IICRC certification (Firm #70044891) and California contractor license #1105699. Daniel Arzate appears to be the founder, with Fernando Ponce serving as the primary project manager across most recent jobs. Blog content on their site is authored by Arzate and dates back to late 2023.
A 4.9-star rating across 53 Google reviews with zero negative reviews in the last 18 months is unusually clean. Multiple Local Guide reviewers with established review histories confirm the pattern, which makes it harder to attribute to review management alone.

Review consensus
Fernando Ponce is the name that comes up most often — reviewers describe him as communicative, reliable, and experienced, with multiple people calling out his project management specifically. Daniel Arzate gets praise for honest assessments, same-day inspections, and willingness to explain the full process. Several reviewers note that Dansel was responsive on weekends and holidays. Aaron Moore's review stands out: Fernando talked him out of spending $2,000 on unnecessary work, telling him he could handle it with soapy water. Risa Kawai used them three times for separate water issues. Selena is mentioned once for providing detailed process explanations for a crawl space mold job.
0 found across 53 total reviews at 4.9★. No recent negative reviews to analyze. The company has maintained a 4.9-star average across 53 reviews with zero complaints at 3 stars or below in the last 18 months.
The review pattern suggests a company where the owner (Daniel) handles initial assessments and sales, while Fernando Ponce manages most active projects. Multiple reviewers mention being referred through insurance companies, which indicates Dansel is on preferred vendor lists for at least some insurers. This insurance pipeline likely drives a significant portion of their business and may explain the consistently high satisfaction — insurance-referred work often has clearer scoping and payment expectations.
Fernando Ponce (project manager — praised repeatedly for communication, reliability, and honesty). Daniel Arzate (owner — praised for same-day inspections, honest recommendations, and detailed explanations). Selena (role unclear — praised for detailed process explanation on a crawl space mold job).
With 53 reviews at 4.9 stars and no recent complaints, Dansel has an unusually clean track record. Ask for Fernando Ponce as your project manager if the job involves mold or water damage — he draws the most specific praise. Get an independent mold test before signing a remediation contract, since Dansel does both testing and remediation.
Keep in mind
- Dansel does both mold testing and mold remediation. This is a conflict of interest — the company inspecting your mold also profits from the remediation work. Consider getting an independent mold assessment from a separate hygienist before committing to their remediation scope.
- Their service area claim spans 20+ cities from Oakland to Palo Alto to Milpitas. Response times and crew availability may vary significantly depending on how far you are from their San Jose or Fremont offices.
- The website lists plumbing and lead removal services alongside core restoration work. There is no detail on the website about crew qualifications or scope for those ancillary services — ask specifically about who handles plumbing jobs.
- With zero negative reviews in 18 months across 53 total reviews, there is no complaint data to evaluate. This is a strong signal, but you have no window into how the company handles dissatisfied customers.
