Mold Inspection

Mold Inspection and Moisture Mapping: what it covers

Quick answer

A mold inspection is a walk-through of the basement, crawl space and framing, combined with moisture meters and thermal imaging to find wet materials you cannot see. In Olathe the crew maps readings across walls, floors and joists, notes where water has been, and records everything in writing. It does not usually include lab sampling, because EPA guidance generally does not recommend mold sampling.

Buyers and sellers of houses built in the 1950s and 1960s in Prairie Village, Roeland Park, Merriam and Mission often ask for the basement and crawl space to be checked before closing. Those houses usually have block basements, original floor drains and laundry standpipes, and mature oaks growing over clay sewer laterals. A check before the sale shows what is wet and where, so nobody is working from a guess.

Olathe Water Damage Restoration sends a technician to the lower level with moisture meters and thermal imaging, mapping readings on walls, slabs, joists and subfloor. Phones are answered 24/7, and a crew is dispatched as fast as one is available. Inspection is a separate job from mold remediation, which covers removal and rebuilding if growth is found.

The point of the visit is evidence, not alarm. EPA guidance says mold can grow on wood, drywall, carpet and furniture left wet for more than 24 hours, so readings matter more than a musty smell. Where an area is wet but shows no growth, the crew says so, and where growth is present, the findings say exactly where.

Warning signs

Signs you need mold inspection and moisture mapping

Do not cut into walls, pull baseboards or lift carpet to look for growth, because disturbing suspected mold releases spores into the room and the air system. Keep children and anyone with asthma or allergies out of the space until it has been checked. Mold can trigger allergy and asthma symptoms in some people. Do not mix bleach with other cleaners, and do not treat a suspected patch yourself before the crew has mapped it.

  • A musty smell that gets stronger when the furnace or a dehumidifier cycles on
  • Fuzzy or powdery growth, gray, white, green or black, on the rim joist, sill plate or back of drywall
  • White crusty deposits on block walls, called efflorescence, which means water has moved through
  • Tide lines or staining at the same height along a wall
  • Carpet or laminate that cups, lifts at seams or feels damp underfoot
  • Peeling paint or bubbling on basement walls and along the bottom of closet doors
  • Damp dirt in a crawl space, or a dehumidifier that empties several times a day
  • Condensation on cold water lines or ductwork in a closed-up lower level
Options

Types and options for mold inspection and moisture mapping

Pre-sale basement and crawl space check

This applies to buyers and sellers of 1950s and 1960s houses in Prairie Village, Roeland Park, Merriam and Mission. The visit covers the lower level, readings, photos and a written summary. It is not a substitute for a full home inspection, so ask the agents what document the sale requires before the crew arrives.

Follow-up after a known leak

After a burst pipe, sump failure or basement flood that was already dried, a check confirms the drying reached the framing and subfloor. Readings are compared with earlier ones so any remaining wetness is clear. This is common after a finished basement has been opened and rebuilt.

Crawl space inspection

Older houses over shallow crawl spaces, and farmhouses in rural parts of the county, need a different walk-through. The crew checks the ground, the joists, the sill plate and any standing water. Access is often the main factor in how long the visit takes.

Check before disturbing older materials

Before renovation in a pre-1980 house, the crew can map moisture and note suspect areas. This is not asbestos or lead testing. Joint compound, textured ceilings, floor tile and pipe insulation can contain asbestos, so check with KDHE and the EPA before disturbing them.

Skip the guesswork. Call for a straight answer.

Tell us what's happening and we'll tell you honestly whether it's a quick fix, and what mold inspection and moisture mapping should cost.

What does a mold inspection check?

A technician looks at framing, subfloor, drains and stored materials for staining and growth, then maps moisture across the space. The result is a written record of where moisture is and what it looks like.

Visual work comes first. The crew checks the rim joist, the sill plate, the base of the wall board, the subfloor where it can be reached, and the floor drain and sump pit for staining or tide lines. Anything that looks like growth is photographed before anyone touches it.

Meters read the surface and the material behind it. Thermal imaging shows cooler areas on finished walls and floor coverings that may be holding water. Readings are logged by location so the same spots can be checked again after drying or repair.

Why are 1950s and 1960s basements checked before a sale?

Those houses have older drains, block walls and single bathrooms, and the clay under many of them holds water against the foundation for long periods.

Inner-ring houses from that period typically have block basements with original floor drains and laundry standpipes. Many sit beneath mature oaks, and roots and clay laterals can slow drainage in ways that first show up as dampness in the lowest room.

The soils under much of Johnson County are smectitic clay. Clay shrinks in a dry August and swells in a wet spring, and its low permeability keeps water against a wall instead of draining it away. A basement dry in July can be wet in March, so a single reading on one dry day can mislead.

How is moisture mapping different from a smell test?

Mapping records where moisture is, with numbers and images. A musty smell only tells you something has been damp at some point.

A smell can come from old carpet, stored boxes or a dehumidifier that needs emptying, and it does not show how far a wet area reaches. Readings at set points along the wall base, slab edge, joists and subfloor show the actual spread.

The crew can give you the readings and photos to keep for your own records or for a claim you choose to file. Coverage is decided by your insurer under your own policy, so check the policy and ask your agent before relying on the map for a claim.

What changes the scope and price of an inspection?

The size of the lower level, how much of it is finished, access, and any past water damage or growth all affect the visit. The price is confirmed on site before any work begins.

A small unfinished basement with clear access is a short visit. A finished lower level with carpet, drywall, built-in cabinetry and a bathroom takes longer, because the crew checks what can be reached without destroying the finishes.

Crawl spaces with dirt floors, tight openings or standing water add access time. A known past sewage backup or growth already on the framing changes the job, and any removal is quoted separately after the area has been seen. Nothing is priced over the phone.

Can I use the report when I sell or file a claim?

The crew gives you readings, photos and a written summary. Whether a buyer, lender or insurer accepts it is their decision.

Ask the buyer's or seller's agent what document the transaction requires before the visit, so the crew can record what is needed. This visit does not replace a formal home inspection if the sale calls for one.

For a claim, take photos before anything is moved, call your insurer early and keep the readings with your records. The Kansas guide to water damage insurance claims explains the usual steps and the Kansas Insurance Department complaint route.

Our process

How our mold inspection and moisture mapping visit works

  1. Describe the house

    Phones are answered 24/7 and a crew is dispatched as fast as one is available. Tell the operator the age of the house, which rooms are finished, and whether there has been water, a backup or a smell. Those details decide which tools come along.

  2. Photograph and walk the space

    The technician photographs the lower level before anything is opened or moved. The basement or crawl space is then walked, and staining, tide lines, damp dirt and any growth are logged by location.

  3. Map the moisture

    Meter readings are taken at set points on walls, floors, joists and subfloor. Thermal imaging is run across finished walls and floor coverings, where a cool surface can point to water underneath.

  4. Check the connected systems

    The crew looks at the floor drain, sump pit, furnace and water heater area, dryer vent and any ductwork that reaches the lower level. The ground and ventilation of a crawl space are noted. Air is not sampled, because EPA guidance generally does not recommend it.

  5. Give you the written findings

    You receive a summary with readings by location, the photos and a plain statement of what was seen. If growth or ongoing moisture is found, any removal or drying work is quoted separately after the crew has seen it.

Johnson County

Why mold inspection and moisture mapping is different in Johnson County and the Kansas side of the metro

Inner-ring houses from the 1950s and 1960s in Prairie Village, Roeland Park, Merriam and Mission share a pattern: block basements, original floor drains, laundry standpipes and oaks over clay laterals. The lower level is usually where moisture shows first, which makes a pre-sale check most useful there.

Johnson County clay holds water through spring and shrinks as it dries in late summer. Both movements work on the foundation, so a check in one season can differ from one in another. The July and August 2017 floods on Indian and Tomahawk Creeks are a reason to look at the mapped floodplain. Check any address on FEMA's Flood Map Service Center or the Kansas Division of Water Resources DFIRM viewer.

Phones are answered 24/7 at (833) 490-5225. If a closing date is close, say so when you call, and ask the crew to confirm what document you need before the visit.

FAQ

Mold Inspection and Moisture Mapping FAQs

Do I need a mold test or a mold inspection?

Usually an inspection is the right first step. EPA guidance says sampling for mold is not usually recommended, because a sample cannot show how much is in the structure or where moisture is. The crew looks, maps moisture with meters and thermal imaging, and checks the air system, where growth can spread.

Will the crew remove mold it finds?

Inspection and removal are separate jobs. If growth is found, the crew explains what it sees and where, and removal and containment are quoted after the area has been seen. The mold remediation page covers that work in more detail.

Does Kansas license mold inspectors?

Kansas does not license mold remediation the way some states do, and KDHE says it does not regulate mold in homes. KDHE directs residents to the Kansas Housing Resources Corporation at 785-217-2060. Ask any company which certifications its technicians hold, and check local contractor licensing where it applies.

How soon can someone come out?

Phones are answered 24/7, and a crew is dispatched as fast as one is available. The crew cannot promise an arrival time in advance, because it depends on the calls ahead and where the house is.

Will insurance pay for a mold inspection?

Coverage is decided by your insurer under your own policy, and this site cannot say what it will pay. Read your policy or ask your agent how it treats mold and long-term moisture before assuming anything. The crew can give you readings and photos to share with them.

How do I check a company before letting it in?

Look the company up in the Johnson County Contractor Licensing online contractor search, which shows whether a company is licensed and allowed to work. Ask who will attend and what training they hold. Get the findings in writing before any work starts.

Is an older basement safe to check?

Houses built before 1980 can contain materials that need care. Joint compound, textured ceilings, floor tile and pipe insulation may contain asbestos, so check with KDHE and the EPA before disturbing them. The inspection looks and maps without removing finishes, and it asks you to keep out of any area you suspect has growth.
