What this listing says
Central and Northern Wisconsin homeowners dealing with mold after water damage who want a single company to handle extraction, drying, and mold removal from two offices in Weston and Rhinelander.
Best for
- Homeowners in Marathon, Wood, Portage, or Oneida counties who need mold removal after a basement flood or pipe burst.
- Property owners who want water extraction, structural drying, and mold remediation handled by one company in a single engagement.
- Commercial facilities, healthcare buildings, or industrial sites in Northern Wisconsin needing both restoration and specialty cleaning.
- Homeowners in older homes who need duct cleaning alongside mold work, given K-tech's NADCA credentials and two-office coverage area.
- Anyone needing weekend or after-hours emergency response for water damage that could lead to mold growth.
About this company
K-tech Kleening is a restoration-and-cleaning company headquartered in Weston, Wisconsin, with a second office in Rhinelander. They've been doing this since 1975, when Clarance and Sue Kersemeier started the business. It's now second-generation and family-run.
Mold work is one piece of a much broader operation. K-tech handles water damage restoration, fire damage cleanup, air duct cleaning, carpet and upholstery cleaning, industrial cleaning, and disinfection using SteraMist and Halo systems. Their mold page describes containment, antimicrobial treatments, and post-flood mold removal tied to their water damage work. They do both mold testing and mold remediation in-house.
The company holds IICRC, NADCA, RIA, and SCRT designations and carries BBB accreditation. They run a charitable arm called K-Tech Charities and host an annual golf outing, which suggests real roots in the Wausau-area community.
4.8 stars across 332 Google reviews is a strong number for a restoration company. Only one review at 3 stars or below appeared in the last 18 months, and it contained no text. That ratio suggests the operation runs consistently, though the lack of response to that single negative is a missed opportunity.

Review consensus
Kris gets named repeatedly for upholstery cleaning and water damage work, with reviewers noting he explains the process and sets time expectations before starting. Chris appears alongside Kris on water damage jobs. Craig earned a mention for calling back on a weekend. Joleen handles scheduling and gets credit for fitting customers in quickly. Multiple reviewers across carpet, duct, and water damage jobs note crews arriving early or on time, calling ahead, and finishing faster than expected. Pricing comes up as reasonable in the duct cleaning reviews specifically.
1 found across 332 total reviews at 4.8★. The single recent 1-star review from Christina Sanders in December 2025 contained no text and no owner response. The reviewer has only 2 reviews total and is not a Local Guide. With no details provided, it is impossible to assess what went wrong. The absence of an owner response is unusual given that K-tech responds to most reviews visible on their website.
K-tech's review base is heavily weighted toward carpet cleaning, upholstery cleaning, and duct cleaning rather than mold or restoration work. The water damage reviews that do appear are uniformly positive and mention fast response, but mold-specific reviews are absent from the sample. The owner responses visible on the website are personalized and occasionally include gestures like a $50 gift card for inconvenience, which suggests active reputation management rather than template replies.
Kris (technician — praised for upholstery cleaning and water damage response). Chris (technician — praised for water damage response). Craig (coordinator/manager — praised for weekend callback). Joleen (scheduling — praised for quick appointment booking).
K-tech's 4.8-star rating across 332 reviews is earned mostly on cleaning work, not mold jobs. Ask for references specific to mold remediation before booking. Request Kris or Chris if your job involves water damage leading to mold, since those are the names reviewers associate with restoration work.
Keep in mind
- K-tech does both mold testing and mold remediation. When the same company that identifies the problem also sells the fix, ask whether they will accept a third-party test result or provide one from an independent lab.
- Mold remediation is one of many services here, alongside carpet cleaning, duct cleaning, and fire restoration. If you need a company focused solely on mold, this is not that.
- They claim coverage across 19 counties from Wausau to Door County. That is a large territory for two offices. Confirm response time for your specific location before committing.
- The single recent 1-star review received no owner response. Their response rate on older website-embedded reviews is high, so this may be an outlier, but it is worth noting.
- The website describes antimicrobial treatments and containment methods but does not name specific equipment or testing methodologies. Ask what testing protocol they use and what the deliverable report looks like.
