What this listing says
Twin Cities homeowners dealing with water damage that has turned into mold, who want a single family-owned firm handling mitigation through reconstruction and insurance negotiation under one roof.
Best for
- Twin Cities homeowners who need mold remediation tied to water damage and want one company to handle everything from emergency dry-out through reconstruction.
- Property managers and commercial building owners dealing with mold across multiple units, since Ungerman handles both residential and commercial work at scale.
- Insurance claimants who want a contractor experienced in Xactimate estimates and direct insurer negotiation — they have done this since the software was first adopted.
- Homeowners facing an urgent mold situation who need 24/7 emergency response with same-day dispatch.
About this company
Ungerman is a family-owned restoration company based in Plymouth, Minnesota, serving the Twin Cities metro. Founded in 1977 by Ron Ungerman Sr., they handle the full arc of property damage — emergency mitigation, mold remediation, reconstruction, and insurance claims — without handing you off to another contractor. Mold is one piece of a broader operation that includes water damage, fire damage, storm damage, and remodeling. They do both mold testing and remediation, which means the same company diagnosing your problem also profits from fixing it.
Their mold process follows IICRC S520 standards. They use containment, HEPA air filtration, negative air machines, and antimicrobial application. For mold areas over 10 square feet, they bring in a third-party environmental hygienist for clearance testing — that independent check matters given the conflict of interest. They also handle source identification using thermal imaging and moisture detection equipment. The reconstruction side means they tear out contaminated material and rebuild, so you are not coordinating between a remediation crew and a separate contractor.
Ron Ungerman Sr. was one of the first licensed contractors in Minnesota and the first to use Xactimate estimating software. The company has been operating for over 47 years. They are an IICRC-certified firm, a BBB-accredited member, and a Restoration Industry Association member. They have appeared on HGTV. They assign a dedicated project manager at the start and work directly with insurance companies, including negotiating estimates and recovering depreciation.
At 4.6 stars across 265 Google reviews, the rating is solid but not exceptional. The volume of positive reviews praising communication and project management is genuine. The negatives cluster around finish quality on reconstruction work — paint details, flooring gaps, trim left unfinished — rather than the emergency mitigation or mold remediation itself.
Services
Service area
Ungerman is headquartered in Plymouth, Minnesota, and serves the Twin Cities metropolitan area. Their website claims coverage of the 'entire Twin Cities metro and beyond' without naming specific outer boundaries. Most reviewers reference Minneapolis, St. Paul, and surrounding suburbs.
Review consensus
Taylor is the most frequently named project manager, praised across at least six reviews for communication, patience, and follow-through. Aaron (project manager) and Eric (estimator/supervisor) also appear repeatedly as responsive and organized. Reviewers consistently highlight clear communication, insurance navigation help, and meeting or beating project timelines. Several mention that Ungerman was recommended by their insurance company and they were glad they followed through. Ryan talked a homeowner through an after-hours fix over the phone instead of dispatching a crew. Ron suggested a cost-saving interim fix for a shower leak rather than pushing a full replacement. The mitigation teams draw strong marks for speed and professionalism on emergency water damage.
5 found across 265 total reviews at 4.6★. Reconstruction finish quality is the dominant complaint. Matt described electrical hazards left behind, boot stains on floors, trash and energy drinks left in his apartment, and weeks of delays for a small job — the owner responded with a generic phone number. Samuel Adams detailed a long list of defects from a project four years prior: wrong paint color, roller splatter on porcelain, unfilled holes in trim, flooring not run to walls, and a door frame that was cut loose from its studs and held only by casing. The owner noted he had signed a Certificate of Satisfaction and was not contacted at the time. Kristin Shimshock said Ungerman dropped her as a client after she raised concerns about missed cabinet damage during a water mitigation — the owner responded that no contract was offered and no contracted work was performed. LEF reported a 110% markup on flooring and months of unresolved warranty follow-up. Megan Hanson described five months out of a small home, an estimator she found unprofessional, and ongoing defects a year later including cracking paint and tile issues — the owner offered a phone number.
The gap between Ungerman's mitigation work and their reconstruction work is the structural story here. Emergency response — showing up fast, extracting water, setting up drying equipment — draws almost universal praise. The reconstruction phase, which involves subcontractors doing paint, flooring, and trim, is where quality drops. Multiple reviewers describe sloppy finish details that were not caught before sign-off. Owner responses follow a pattern: a polite acknowledgment followed by a phone number, without engaging with the specifics of the complaint. The one exception is the Samuel Adams response, where the owner noted the signed satisfaction certificate and four-year gap — that context meaningfully reframes the complaint's weight but does not erase the defect list.

Ron (suggested cost-saving fix — praised). Kirsten (insurance navigation — praised). Mindy (packout team lead — praised). Casey (praised). Rodrigo (praised).

Ask for Taylor or Aaron as your project manager if you can — they have the strongest track records in these reviews. Inspect every detail of reconstruction work before you sign the Certificate of Satisfaction, because getting corrections after that point has proven difficult for past customers. The mitigation side of this company runs well; the reconstruction side needs your active oversight.
Keep in mind
- Ungerman does both mold testing and remediation, which is a conflict of interest. They do bring in third-party hygienists for clearance on jobs over 10 square feet, but you should still consider getting an independent mold assessment before authorizing remediation work.
- The negative reviews almost all focus on reconstruction finish work — wrong paint colors, unfilled holes, flooring not run to walls, trim left unprimed. If your project includes a rebuild phase, inspect the details before signing off.
- Several reviewers reported difficulty reaching their project manager or estimator after raising concerns. One reviewer named Mark and Kayla as unresponsive; another said their estimator dropped them after they raised quality questions.
- Their pricing on insurance work may run high. One reviewer documented a 110% markup on flooring materials compared to the supplier's price. Ask for an itemized materials list if you are paying out of pocket.
- They claim to serve the 'entire Twin Cities metro and beyond,' which is vague. Confirm they will service your specific location before committing, especially if you are outside the core metro.
