Mold and Radon Testing in Harper Woods

Add either to a Harper Woods home or commercial inspection, or book it on its own. We test and we never remediate, so there is nothing to sell you on the back of a result — the number you get is just the number.

How each one works

Radon measured in house on a professional continuous monitor; mold samples to an accredited laboratory:

  • Radon: 48-hour continuous monitor, read on site
  • No mail-in radon kit and no waiting on a laboratory
  • Mold: laboratory results in one to three business days
  • Either can go on the same visit as the inspection

  • Post-remediation mold verification

    Carried out after remediation on the treated area and the areas next to it, to confirm what was found. More about mold inspection and testing

  • Sewer camera inspections

    A damp basement can have several causes, and the buried sewer line is the one a visual inspection cannot check. A scope rules it in or out. More about sewer scope inspections

Harper Woods housing stock

The median Harper Woods home was built in 1955

Harper Woods has roughly 5,889 housing units and about 84% of them are single-family detached. Homes built in a single stretch tend to wear out in the same places at the same time. That is why when somewhere was built is the first thing worth knowing about it.

The busiest stretch of building here was the 1950s: 3,093 homes, about 53% of everything standing today.

What the figures add

The median owner-occupied home here is valued at $134,900.

  • Older drain and sewer linesAge alone does not tell us what material is installed or what condition it is in. We evaluate accessible interior drain components visually, and a sewer scope is the only way to look inside the buried line.
  • Steel casement windowsThey rust at the frame rather than rot, and the failure shows up first at the glazing and the operators.

None of this says anything about the specific house you are buying. It is the shortlist a Harper Woods home inspector works through in a home of this age, and every item on it gets photographed and written up whichever way it turns out.

Local knowledge

What makes inspecting a Harper Woods property different?

Two things define property here, and they compound each other. The City requires a Certificate of Occupancy on transfer, and more than half its housing was built in the 1950s.

Of about 5,889 units, 3,093 date from the 1950s and another 1,082 from the 1940s — some 71% of the city built inside two decades. Only ten units have been built since 2000. This is a postwar city that has stayed one.

On the transfer side, the City’s published Certificate of Occupancy procedures state that a certificate is required for all properties, that residential certificates are valid for one year or until the property is sold or transferred, and that certificates expire on any change in use, ownership or occupancy and are not transferable. Getting one means passing a property maintenance and life safety inspection through the Building Department.

So a sale here triggers a municipal inspection, and the building being inspected is seventy years old. That is a combination worth planning for rather than discovering, and the planning starts with knowing what the City looks at — and what it does not.

Before you buy

Buying a property in Harper Woods? Pay attention to these four things

  • The certificate does not come with the house

    Certificates expire on any change of use, ownership or occupancy and are not transferable. A new one means a new inspection.
  • Old unpermitted work does not age out

    The City states that work found done without permits, no matter how long ago, requires a permit and inspections or removal of the violation.
  • Seventy-year-old electrical is the norm

    Fuse panels, two-outlet rooms and missing GFCI protection are all live issues in 1950s housing, and the City checks for them.
  • Ask the City about the service line

    Harper Woods has known lead service lines and samples for lead and copper. The Building and water departments are where that question belongs.

The certificate of occupancy

What the City inspects, and what it means for a sale

The City’s Building Department handles certificates of occupancy, property maintenance, residential code enforcement and residential rental inspections. Its published Certificate of Occupancy procedures set out how the process runs, and it is worth confirming the current version with the department directly — a document like this gets revised, and what follows is a summary rather than today’s checklist.

The shape of it: the applicant schedules the initial inspection and every follow-up, with 24 hours notice required. If the inspector issues a list of corrections, those must be made and re-inspected — for residential properties, before occupancy. Inspectors do not return automatically; you call. Where applicable, repairs must be carried out by licensed contractors. And on rental property, homeowner permits may not be issued at all — a licensed contractor is required for any work needing a permit.

The line that catches people out is about history: work found to have been done without permits, no matter how long ago, requires that a permit be issued and the appropriate inspections completed, or the violation removed. In a city where most houses are seventy years old and have been altered by several owners, that is not a hypothetical.

What the inspection covers

The inspection itself covers property maintenance and life safety rather than the whole building. Its published checklist runs to address numbers of at least four inches visible from the centerline of the street, foundation walls kept plumb and free from open cracks, handrails and guards able to take a 200 pound lateral load, screens on openings, heating capable of 68 degrees in habitable rooms, smoke alarms in each sleeping room and on each level, and a long list of specific plumbing and electrical items.

What it is not is an assessment of the building for you. The City is checking the property against a maintenance and safety code; it is not evaluating the roof’s remaining life, the furnace’s condition, the structure, or the drainage. A buyer’s inspection covers the roof, structure, foundation, drainage, electrical, heating and cooling, plumbing and the accessible interior, and reports to you. Plan for both; they answer different questions.

One practical note on who you will be dealing with: the Chief Building Official listed by the City works for a contracted code services provider rather than as in-house staff. That is common in cities this size and says nothing about the standard of the work — it is simply useful to know when you are chasing a file or a re-inspection.

Seventy-year-old wiring

What the checklist tells you about 1950s electrical

You can read a lot about a city’s housing from what its inspectors are told to look for. Harper Woods publishes a checklist that includes the instruction that screw-in fuses must be type S only.

That single line tells you fuse panels are still in service here. Type S fuses are the rejection-base kind — once fitted with the adapter, a 15 amp circuit will not accept a 20 or 30 amp fuse. The reason the requirement exists is that the ordinary Edison-base fuse will accept anything, and over-fusing a circuit is one of the classic ways a house of this era catches fire.

The rest of the electrical checklist reads the same way. Every habitable space must have at least two separate and remote receptacle outlets — a requirement that only needs stating where rooms with one outlet exist. Laundry areas and bathrooms need ground fault protection, as do kitchen outlets within six feet of the sink. Painted-over switches and outlets have to be replaced. All of these are the signatures of original 1950s wiring that has been added to rather than replaced.

The whole electrical picture

On a house of this age, what we are looking at is the whole electrical picture rather than a compliance list: the service size and its condition, the panel and how it has been added to, the type and condition of the branch wiring where it is visible, grounding, and the junctions where newer work meets original. A 1950s house that has been partially rewired often has a modern-looking panel feeding original circuits, which is precisely the situation a walkthrough cannot detect.

The same checklist is specific about a few other things worth knowing: cooking appliances may not be used to provide space heating; fireplaces may require a visual safety inspection by a licensed contractor; bedroom doors may not have keyed locks and emergency escape openings must operate from inside without keys or tools; exterior hose bibs need vacuum breakers; a dishwasher needs an air gap on the drain; a bathroom needs a fan vented outside or an operable window; and a dryer must vent through metal pipe over a run of less than twenty-five feet.

Lead in drinking water

What the City publishes, and what it asks you to understand

Harper Woods publishes a water safety page and a public advisory about lead, and the City is careful about what the numbers mean. So are we.

The City states that changes to the Michigan Safe Drinking Water Act added new sampling rules, and that these require communities with lead service lines and older housing stock — Harper Woods among them — to do more sampling. Critically, it explains that the new method is expected to produce higher lead results not because the water source or quality has changed, but because the Act sets more stringent sampling and analysis procedures. The City has been testing for lead and copper since 1992, and reports that four of thirty targeted sites with known lead service lines returned elevated results.

Two things that follow

Two things follow for a buyer. The first is that Harper Woods has known lead service lines — the City says so plainly, and the housing age makes it unsurprising, since the materials in question were normal when this city was built. The second is that whether a particular address has one is a question for the City, not something anyone should infer from a build year.

We do not test water. Water testing is a separate discipline with its own certified laboratories, and the City links the state list of them. Nothing in a building inspection substitutes for a water test, and we will not tell you what is in a pipe we have not seen.

What an inspection contributes is an observation of the visible supply piping — what it appears to be where the service enters the building, and along accessible runs in a basement or crawlspace, including where visible piping is galvanized rather than copper or plastic. That narrows the question. The City’s water safety page and its advisory are where the authoritative answers live, alongside the state and county resources it links.

The buried line

A pipe laid when the city was built

The sewer lead running from a Harper Woods house to the main was, for most of the city, laid in the 1940s or 1950s along with everything else. Seventy years later it is the one component no visual inspection reaches.

That is long enough for roots to have found a joint, for ground movement to have displaced a section, or for a repair to have been made that nobody now remembers. We will not name a material from a build year, because no authoritative source establishes what Harper Woods leads are generally made of — the City’s code of ordinances is the place to start if you want the local requirements in full.

Given that the City already requires an inspection at transfer, adding a look inside the line is a small addition to a process you are going through anyway — and it covers the one thing the municipal inspection does not.

A sewer camera inspection records what is actually inside: roots, cracks, displaced joints, bellies or blockages where they exist, and a clear run where they do not. It is added to the same visit rather than booked separately. Alongside it, commercial building inspections follow the CCPIA standard, and radon testing or mold inspection and testing can be added to a residential or commercial visit. Get in touch to talk through a particular property.

Radon in Wayne County

Wayne County is EPA Radon Zone 3

Zone 3EPA radon zone
17%of Wayne County tests came back at or above 4 pCi/L

Zone 3 is the lowest of the three EPA categories — the predicted average indoor level across the county is below 2 pCi/L. So Harper Woods is not where the state’s worst readings turn up, and we would rather say that plainly than imply otherwise. What a zone cannot tell you is anything about one house: 17% of tests actually run in Wayne County still came back at or above the EPA’s 4 pCi/L action level, which is about one in six. A zone is an average taken across a whole county, and no house is an average.

Reviews

What people near Harper Woods say

  • Ora from Trademark did an incredible job with the inspection and sewer scope of the home I am in the process of buying. He was very thorough, explained everything to me from the start, and made it all super easy to understand which definitely helped to put me at ease a bit more. Highly recommend this company!

    GoogleMariah HartmanWestland, MI
  • Jim was prompt and thorough during the mold testing. Clearly gave us an explanation about mold and testing process he was going to conduct. Testing was followed by a written report. I would recommend everyone use a third party to test mold, independent from the company conducting remediation work. I would hire Trademark again and strongly recommend them.

    GoogleAlberto PicconeNorthville, MI
  • Cowboy “Jim” just did Mold Testing in my parents’ basement. He was Professional, explained the what, how and yet of everything to my Senior parents. Our results came back super quick. He even referred us to the resources on the Trademark website for me to use to fix the leaky basement. It’s 1 stop shopping with Trademark.

Questions

Harper Woods home inspector questions

  • Do I need a certificate of occupancy to sell a house in Harper Woods?

    The City’s published procedures state that a Certificate of Occupancy is required for all properties, that residential certificates are valid for one year or until the property is sold or transferred, and that certificates expire on any change in use, ownership or occupancy and are not transferable. Obtaining one requires passing a property maintenance and life safety inspection through the Building Department. Confirm current requirements and fees with the department directly — procedures get revised.

  • Does the City inspection replace a home inspection?

    No. The City’s inspection checks the property against a property maintenance and life safety code — address numbers, handrails, screens, smoke alarms, specific electrical and plumbing items. It is not an assessment of the roof’s remaining life, the furnace’s condition, the structure, or the drainage, and it is not reported to you. A buyer’s inspection covers the building as a whole and answers to you. Plan for both.

  • What happens if previous work was done without a permit?

    The City takes a hard line: work found to have been done without permits, no matter how long ago, requires that a permit be issued and the appropriate inspections completed, or the violation removed. In a city where most houses are seventy years old and have passed through several owners, this is worth asking about before you are the one holding it.

  • Why does the City require type S fuses?

    Because fuse panels are still in service here, and type S fuses are the rejection-base kind. Once the adapter is fitted, a 15 amp circuit will not accept a 20 or 30 amp fuse. An ordinary Edison-base fuseholder will accept anything, and over-fusing a circuit is one of the classic ways a house of this era catches fire. It is a small requirement that tells you a lot about the electrical stock.

  • Does Harper Woods have lead service lines?

    The City says it does. Its water safety page states that Safe Drinking Water Act changes require communities with lead service lines and older housing stock, Harper Woods among them, to do more sampling, and reports that four of thirty targeted sites with known lead service lines returned elevated results. The City also explains that higher results under the new method reflect more stringent sampling procedures rather than a change in water source or quality. Whether a particular address has a lead service line is a question for the City.

  • Do you test water for lead?

    No. Water testing is a separate discipline with its own certified laboratories, and the City links the state list of them. What an inspection can report is what the visible supply piping appears to be where it is accessible — at the point the service enters the building and along exposed runs — which narrows the question without answering it.

  • How old are homes in Harper Woods?

    Overwhelmingly postwar. Of about 5,889 housing units, 3,093 were built in the 1950s and 1,082 in the 1940s — roughly 71% of the city inside two decades — with 775 from the 1960s. Only ten units have been built since 2000, and around 84% is single-family detached. Expect original-era wiring and plumbing behind whatever has been updated on the surface.

  • Should I consider a sewer camera inspection here?

    Yes. For most of the city the sewer lead was laid in the 1940s or 1950s along with the house, and seventy years is long enough for roots, ground movement or a forgotten repair to have changed what is down there. We will not guess a material from a build year. Putting a camera down the line documents roots, cracks, displaced joints, bellies or blockages where they exist, and is added to the same appointment — covering the one thing the City’s own inspection does not.
