The boom years built it, and the houses are showing their age

Mold Detection Dog in Plano, TX

Much of Plano went up in a hurry, and many of those houses now have forty years or more of plumbing, settling, and weather behind them. Ember, our mold detection dog, tracks the scent of hidden growth. Ryan, a licensed Texas Mold Assessment Consultant, confirms each alert and tells you what to do about it.

Two decades of building

Plano Grew Up Fast, and Its Houses Are Catching Up

Plano counted 3,695 people in 1960 and 17,872 in 1970. By 1990 it had 128,713, and the Census now estimates 293,028, according to U.S. Census QuickFacts. Adding more than 110,000 residents in twenty years meant building neighborhoods at a pace few Texas cities have matched.

Those boom years are now a long way back. Plumbing installed in that era has been through decades of pressure, the clay under the slab has swelled and shrunk through every drought and wet spring, and siding and trim have taken years of sun and rain. Water damage in a house like that rarely announces itself. A mold detection dog does not need it to. Ember follows scent, so she can point to growth behind a wall that looks perfectly sound.

Where Ember checks

Where Moisture Hides in an Older Plano Home

Houses from Plano’s growth years tend to share the same weak spots. A mold detection dog search works through each of them.

Cast Iron Drains Under the Slab

Many homes from the 1970s and 1980s have cast iron drain lines under the foundation. As they age, they can crack or corrode, and the leak stays out of sight below the floor.

Polybutylene Supply Lines

Gray polybutylene pipe was used in many homes built from the late 1970s into the 1990s. Fittings can fail without warning, and a slow drip inside a wall can go unnoticed for a long time.

Foundation Movement

North Texas clay swells when wet and shrinks when dry. Over the years that movement can open gaps around doors and windows and put stress on the pipes that run through the slab.

Hardboard Siding and Trim

Pressed wood siding and trim were common on houses of that era. Once the paint wears thin, the boards soak up water, swell at the bottom edge, and pass that moisture to the wall behind them.

After Ryan confirms mold

Five Texas Steps to a Remediation Certificate

Once an alert from our mold detection dog is confirmed, Texas spells out the order of the work and who is allowed to do each part.

1

Assessment MAC / MAT

Ryan documents the findings in a written assessment.

2

Protocol MAC only

Ryan writes the protocol the removal company must follow.

3

Remediation MRC

A licensed Mold Remediation Contractor handles the removal. We stay out of that part.

4

Clearance MAC

A Consultant runs clearance testing on the finished areas.

5

Certificate: CMDR

A passing result leads to the Certificate of Mold Damage Remediation.

Foundation Repair Coming Up?

Lifting a slab can put stress on the pipes inside it, and plumbers often suggest testing the lines once the work is done. A mold detection dog visit before or after the repair shows whether any leaks have already fed growth in the walls or floors.

Start to finish

How a Plano Mold Detection Dog Visit Unfolds

Every visit has three parts, and each one sets up the next.

Ember Searches

Ember works the house room by room, checking baseboards, vanities, closets, and the seams in the floor. She is trained on the scent of active mold, so her alert can mark a spot with nothing showing on the surface.

Ryan Confirms

Ryan follows up on each alert with his own inspection and takes samples where they help. Then he tells you, in everyday language, which findings need attention.

You Receive a Plan

As a licensed Consultant, Ryan can write the remediation protocol himself. We never remediate a job we assess, which keeps our recommendations free of any cleanup sales pitch.

Check this first

Not Every Mold License Can Write the Plan

Texas treats a detection dog visit as a mold assessment, so the person with the dog needs a state license. Which license they hold decides what you have in hand when the visit ends.

Technician: MAT

  • Licensed to assess and sample.
  • Cannot write the remediation protocol.
  • You still need a Consultant for the plan.

Consultant: MAC (Ryan’s license)

  • Assesses, samples, and writes the protocol.
  • Works every alert from our mold detection dog.
  • Returns for clearance testing afterward.

When to call

Know the History Before You Close

Sellers cannot tell you about leaks they never knew happened. A mold detection dog search during your option period checks the whole house by scent, and Ryan explains what the results mean before you sign.

It is a good time to look. Leveling a slab can stress the pipes inside it, and any older leak under the floor may already have caused growth. Ember can search the house and Ryan can tell you what she found.

It is usually a gray, flexible plastic line, often stamped PB2110, and you may see it near the water heater or under sinks. A plumber can confirm it. Ember checks for mold that past leaks may have left behind.

Swollen siding means the boards have been taking on water. That moisture can reach the sheathing and framing behind them, so it is worth having Ember check the inside of that wall.

No. We do not remediate jobs we assess. If removal is needed, Ryan writes the protocol and a licensed Mold Remediation Contractor does the work.

Rated 5 out of 5

After Ryan e-mailed the test results, he spent 45 minutes going over them with us on the phone. Line by line he explained the problem, the solution, and the estimated cost, telling us what was serious and what wasn’t. He is the most thorough inspector I’ve ever dealt with on anything.

We were in a quick option period on a house. He got in, did a complete thorough walkthrough, sent samples to the lab, and wrote up a report with a massive amount of broken-down details, all before our option period ended. Highly recommend!

Chris Falcon

Rated 5 out of 5

He didn’t just take air and surface samples, he explained each step so we understood how the testing works and what the results would show. By far more honest and customer-focused than other companies we’ve used.

Ryan brings an educational approach: not only what mold is and the signs of it, but how it can affect your body. He helped us identify a few spots causing allergic reactions for our children, and gave us actionable steps to prevent it going forward.
