Written for this climate
Deep frost, ice dams, winter vapor drive and a river that raises the water table — not advice recycled from a market with none of those things.
About
About Janesville Pro Mold Removal
Mold help for Janesville, Rock County and the Rock River communities — built around how buildings in this climate actually fail.
Why this site exists
Built for Southern Wisconsin’s Housing
Janesville Pro Mold Removal is a free resource for property owners across Janesville and Rock County, and a phone line that reaches a mold specialist working in this area. Call, describe what you are dealing with, and you will get a straight view on what it is likely to be and whether it is urgent — before anyone visits and before you spend anything.
Most mold advice online is written for a warm, humid, slab-on-grade market. Applied here a good deal of it is not merely unhelpful but backwards — the standard suggestion to open the basement windows and air it out being the clearest example, since in a Wisconsin July that imports the moisture rather than removing it.
This region works differently. Nearly every house has a full basement. The vapor drive runs outward for five months of the year and inward for three. The Rock River sets the water table for everything on the low ground. And the building stock runs from limestone cellars laid before the Civil War, through the worker housing of the industrial years, to envelopes tight enough that household moisture has nowhere to go. Each of those fails in its own way and needs its own answer, community by community.

What sets us apart
What Sets Us Apart
Standards, not shortcuts
IICRC S520 is the reference throughout: containment, removal of what cannot be saved, drying to a documented target, and independent verification.
Published cost ranges
Real south-central Wisconsin figures on the page, including the situations where the honest answer is that you need not spend anything at all.
Community by community
Nineteen area pages written around the housing that is actually there. A limestone cellar on Courthouse Hill and a 2015 basement in Milton do not fail the same way.
Who writes this
The People Behind the Guidance
Four beats, divided by what the buildings here actually do rather than by service line.
Curt Boysen
Basements, foundations & moisture diagnosis
Curt writes the below-grade coverage on this site — limestone and rubble foundations under the older east-side housing, the block walls of the postwar subdivisions, frost depth and footing drains, and the finished-basement assembly that fails quietly for years in a cold climate. Most of what property owners here call about starts below the first floor.
Ilene Radtke
Historic & pre-war housing
Ilene covers the city’s older building stock — the Italianate, Queen Anne and Second Empire houses of Courthouse Hill, the worker housing of Look West and the Fourth Ward, foursquares and early bungalows, and the recurring problem of modern low-permeability materials being used on buildings designed to dry outward.
Marcus Feld
Water damage & the Rock River
Marcus covers water damage and the first forty-eight hours: frozen and burst supply lines, sump failures during a February thaw, and the Rock River flood record through the June 2008 event that put water into basements from Blackbridge to Beloit — including what was left half-finished in the months afterwards.
Tessa Nguyen
Cost, insurance & hiring
Tessa covers the parts of a mold project that are not building science: what the work actually costs in south-central Wisconsin and what moves the price, what a Wisconsin homeowners policy does and does not pay for, what the state does and does not license, and which documents are worth asking a contractor for before anything is signed.
Worth knowing
One Thing About Wisconsin
Wisconsin issues no state license for mold inspection or mold remediation. There is no board, no exam and no register specific to the trade, which is the same position as most states and is not a reason for alarm — plenty of excellent contractors work here.
It does mean the checks are yours to make. What the state does regulate is construction work on one- and two-family dwellings, through the DSPS Dwelling Contractor credential, and that is checkable free online. So for the rebuild half of any project there is something concrete to verify.
The practical list for anyone you hire: general liability and pollution liability insurance, current IICRC S520 certification for the person actually doing the work, a written scope of work before anything starts, and the DSPS credential for any construction. And independent clearance testing at the end, by somebody who did not perform the remediation — in an unlicensed trade that is the main external check that exists.
Ask any contractor for
- General and pollution liability insurance
- IICRC S520 certification
- A written scope before work starts
- Wisconsin DSPS Dwelling Contractor credential
- Independent clearance at the end
How it goes
What Working With Us Actually Looks Like
No part of this is unusual, and none of it should be a surprise on the day.
- A phone call, free, with somebody who has done the workDescribe the building, the season the problem appears in and what you can see. A good proportion of these calls end with a suggestion you can carry out yourself, and no visit.
- An inspection, if one is warrantedOne to three hours. Moisture metering, thermal imaging where it helps, and the attic, basement or crawl space physically entered rather than looked into. Sampling only where it answers a question you actually have.
- A written scope before anything startsWhat is being removed, to what cut lines, what containment is used, what the drying target is, and what is excluded. A number on its own is not a scope.
- The work, documented dailyMoisture readings at marked points, equipment in place, and photographs. This is what you keep for an insurer or a future buyer.
- Independent clearanceArranged with somebody who did not do the remediation. In a state with no licensing, this is the external check that exists, and we would rather it was somebody else’s signature on it.
- The moisture source, in writingEvery job ends with a statement of what let the water in and what has been done about it. If that is missing, the job is not finished, whatever the air sample says.
When We Will Tell You Not to Hire Us
These come up often enough to be worth stating in advance:
- Under about ten square feet on a hard surface. EPA guidance says this is homeowner territory, and it genuinely is. Detergent, water, gloves and an N95, then fix whatever wet it.
- Window condensation with no growth yet. That is a humidity reading, not a remediation job. Ventilation and a hygrometer first.
- A single damp patch that appears every July and dries in the fall. Usually condensation on cold masonry, and usually a dehumidifier and some air sealing.
- An active leak nobody has stopped yet. Plumber first. Remediation into running water is a rehearsal.
- A test with no question attached. If you can see it, testing rarely changes what happens next.
The commercial logic is not complicated: a company that recommends work it does not believe in gets one job, and a company that says so gets the call two years later when something real happens.
What We Do Not Claim
We have no state license in mold remediation, because Wisconsin issues none to anybody. We hold no credential that certifies a diagnosis of your health, and we will not offer one. We do not sell testing as a subscription, we do not use the phrase “toxic black mold” to price a job, and we do not treat a species name as a reason to charge more. Where a question is genuinely unsettled — and several of them are — the pages on this site say so rather than resolving it in whichever direction sells better.
