Mold and Radon Testing in Addison

Add either to an Addison 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

Also available

  • 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

Addison housing stock

The median Addison home was built in 1954

Addison has roughly 294 housing units and about 69% of them are single-family detached. Age is the most useful single fact about a house before anyone has seen it. It narrows down what is worth checking first, and it is why two places of much the same size can need quite different inspections.

If the town has a defining decade it is the years before 1940, which accounts for 118 homes, around 40% of the housing stock.

The other numbers

The median owner-occupied home here is valued at $129,000.

  • Galvanized supply linesThe corrosion is internal, so age and water pressure tell you more than appearance.
  • Asbestos floor tile and pipe wrapCommon through about 1980. Intact and undisturbed is the usual finding and usually the right outcome.

Treat this as a starting list, not a diagnosis. An Addison home inspector checks these things early in a home of this age and then records what is genuinely there, which is often not what the era would suggest.

Housing figures: US Census Bureau, American Community Survey 2022 five-year estimates.

When Addison was built

  • Pre-194040%
  • 1940s2%
  • 1950s21%
  • 1960s12%
  • 1970s7%
  • 1980s10%
  • 1990s4%
  • 2000s2%
  • 2010s1%
  • 2020s<1%

66% of homes here run on utility gas, and 3 still heat with oil. If yours is one of them, the tank is the thing to ask about — where it is, and whether it was ever buried. Another 6 use bottled or LP gas.

Local knowledge

What makes inspecting an Addison property different?

Start with something practical that will otherwise cost you an afternoon. At the time of writing, the Village of Addison’s web address does not work. It redirects to a secure address whose certificate belongs to a different municipality altogether, so a browser shows a security warning, and past that the page returns a hosting error saying the site is not a valid client site. Search engines still list its old pages.

We mention it only because you will find those links and they will waste your time. It says nothing about how the village is run — a lapsed arrangement with a web vendor is not a statement about a community. But it does mean the online answers about a property here are not where you would expect them, and it is worth telephoning the village office directly rather than hunting for a website.

The layer either side

What does work, and works well, is the layer either side of the village. Addison sits across two townships — Rollin and Woodstock — and both publish real, current sites. Above them, Lenawee County holds the things counties hold.

So the first question on any Addison property is which township it is in, because that decides which office you are dealing with, and the two are not interchangeable. They keep different hours, they publish different things, and they are based in different places.

A home inspection is not a code inspection or a permit search and we do not present it as one. What we establish is what is physically there and what condition it is in, and we flag work that looks as though it was done without the benefit of a permit — which gives you the specific question to take to the right office.

Before you buy

Buying a property in Addison? Pay attention to these four things

  • The village website does not resolve

    Old links still appear in search results. Telephone the village office rather than chasing them.
  • Find out which township you are in

    Addison lies across Rollin and Woodstock Townships, and they are separate offices with separate hours.
  • Wells and septic go to the county

    Lenawee County’s health department handles them, and an evaluation needs booking early in a purchase.
  • About a third is not detached housing

    Roughly 69% of 294 units are single-family detached, so an inspection here is not always of a whole standalone building.

Where the answers live

Two township offices, and a county behind them

Woodstock Township publishes a zoning and ordinance administrator and a list of its inspectors, along with minutes for the township board, the planning commission, the zoning board of appeals, the Addison Fire Board and the sanitary drain. Its office keeps different hours on every day of the week — longer on Monday and Tuesday, closing at one o’clock from Wednesday to Friday — and the supervisor is available by appointment.

Rollin Township, based at Manitou Beach, takes property tax payments online and publishes a tax brochure. It also runs sewer billing, with an ACH form so a sewer payment can be charged automatically to a checking or savings account on the due date. Its hours are published per official rather than for the office as a whole, so the supervisor, clerk and treasurer each keep their own windows.

That last detail is worth planning around. If you need the clerk and the treasurer in the same week, check both sets of hours before you drive out, because they do not overlap as much as you would assume.

Above the townships, the county holds the rest. Woodstock Township links directly to the Lenawee County health department for wells and septic systems, to the county drains office, and to the county road commission for anything at the road edge.

One more verifiable detail, mentioned because it saves a click: the township’s own link to the village fire department page points at the village domain, and that link does not currently resolve either.

The housing

A 1954 median, and a third of it not detached

Addison has roughly 294 housing units with a median build year of 1954, and about 69% of them are single-family detached. That second number matters as much as the first: close to a third of the housing here is something other than a standalone house, so we establish which situation a property is actually in before anything else. What is shared, what is yours, and who is responsible for the roof above you are different questions in a building with more than one unit.

On the detached stock, a mid-1950s median puts the usual questions in play. Electrical systems are usually the accumulated work of several decades: mixed wiring types arriving in the same enclosure, ungrounded receptacles, a panel added to more than once, and an original service capacity sized for a 1954 household. We report what is there and photograph it either way.

Plumbing has usually been renewed in part rather than in whole, which concentrates the interesting questions at the transitions between materials. Heating and water heating equipment will be several replacements deep. Roof coverings will be on a second or third generation, and the flashings and penetrations matter more than the covering itself.

Foundations of the period

Foundations of the period are typically block, and their condition depends far more on how water has been managed around the building than on how they were built. Where the downspouts terminate, whether there is a sump and where it discharges to, and how the ground falls away from the walls tell you more about a basement than a dry-day look at it will.

This is lake country, and Rollin Township is based at Manitou Beach, so some of the housing in this area began life as seasonal building. Where that is the case the questions shift to the conversion: insulation added later and unevenly, heating retrofitted into a structure that never had any, and plumbing routed through uninsulated spaces. Radon testing and mold inspection and testing can be added to any visit, and commercial building inspections to the CCPIA standard are available for commercial property.

The buried line

Sewer, septic, and the pipe that is yours either way

Rollin Township runs sewer billing, which establishes that a sewer system exists on that side. It does not establish which parcels are connected to it, and we found nothing settling the position for Woodstock Township — so we are not going to tell you what any particular Addison property is served by. Confirm it in writing for the parcel.

If it turns out to be a septic system, that is specialist work arranged through the Lenawee County health department, and it answers questions no visual inspection can: whether a drainfield is failing, and the true condition of the tank. It runs to its own timetable, so it needs arranging early in a purchase rather than in the last week. A water test on a private well belongs in the same conversation.

The line is yours

Either way the line running out from the building belongs to the owner and no visual inspection reaches inside it. On a median 1954 house that pipe is around seventy years old unless somebody has replaced it, and we will not name a material from a build year — a guess in a report is worse than no statement at all.

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. On a septic property it documents the building drain out to the tank — the stretch a septic evaluation does not examine, and on a lot with mature trees exactly where roots go.

It goes on the same appointment rather than a second visit, and we deliver a full written report with photographs, generally the same day. A buyer’s inspection covers the building; the camera covers the part nobody can see. You can read what our clients say, browse answers to common questions, or get in touch about a specific address in Addison.

Reviews

What people near Addison say

  • I recently hired Trademark for a full home inspection on a new purchase, including sewer scope and radon testing. It was a phenomenal experience from beginning to end. Our inspector, Mitch, did a fantastic job explaining all the findings, and the digital report with photos and videos was superb. Would definitely recommend without hesitation.

    GoogleSalina HamiltonOak Park, MI
  • We had Mitch inspect our prospective house and he was amazing. He was thorough, patient to answer my questions and provide feedback on what areas he would recommend having a follow up expert and why. The office was responsive and I was able to book multiple services to be done in the same visit (inspection, radon test, sewer scope).

    GoogleChris PlaweckiOak Park, MI
  • This is one of the finest companies I have come across - that means serious customer service and professionalism. Justin was the inspector and he was very thorough yet very kind to answers all the questions that came in my mind during inspection. He took enough time, no rush, and a very detailed inspection was conducted. Extremely competitive pricing and timing from the company. 100% recommend to anyone looking for any kind of property inspection!!

Questions

Addison home inspector questions

  • Why can I not reach the Village of Addison website?

    At the time of writing the domain redirects to a secure address carrying another municipality’s certificate, so browsers show a warning, and behind it the host returns an error saying the site is not a valid client site. Old pages still appear in search results. Telephone the village office instead.

  • So where do I get answers about a property?

    From the township the parcel is in — Addison lies across Rollin and Woodstock Townships — and from Lenawee County for wells, septic systems, drains and roads.

  • How do I know which township I am in?

    Ask before you rely on anything. The two are separate offices in separate places with different hours, and which one holds your records depends on where the parcel sits rather than on the postal address.

  • What does Woodstock Township publish?

    A zoning and ordinance administrator and a list of inspectors, plus minutes for the township board, planning commission, zoning board of appeals, the Addison Fire Board and the sanitary drain.

  • What does Rollin Township publish?

    Online property tax payment and a tax brochure, and sewer billing with an ACH form so payments can be charged automatically on the due date. Its office hours are listed per official rather than for the office as a whole.

  • Is the property on a septic system?

    We will not assume. Rollin Township runs sewer billing, which shows a system exists, but not which parcels are connected. Confirm in writing for the specific address and take well and septic questions to the Lenawee County health department.

  • Is every home here a detached house?

    No. About 69% of roughly 294 units are single-family detached, so close to a third is something else. We establish which situation a property is in before anything else.

  • Is a sewer camera inspection worth it here?

    On a median 1954 house the line out from the building is often the oldest untouched component on the property, and on a septic property the run from the house to the tank is nobody’s job by default. A camera inspection goes on the same visit.
