It is easy to overlook the warning signs of excess moisture and impending water damage. Learn to keep an eye out for these all-too-common sources of moisture damage.

Under the Kitchen Sink 

Under the sink is not just for storage and the trash can. It is often the starting point for many water-related problems. Dampness and musty odors are common signs of a leak.
Is a drip in the trap under the sink going unnoticed? It’s a warning sign of potentially serious drain problems.

Is a steady drip at a faucet going unnoticed? Recommend that it be repaired promptly.

Are there damp or stained areas in or under the wall where the plumbing pipes penetrate?

Are there large holes in the wall with smaller pipes coming through? These holes should be filled with appropriate foams, caulks and sealants.

Is the floor beneath the plumbing penetrations soft or stained?

Around the Kitchen Sink 

The kitchen sink is a high-traffic zone that sees more action than almost any other place in the home. 

Is the backsplash cracked?  Are the sink seals cracked or loose?

Is the countertop tile or grout cracked, broken or missing?  Although it may appear to be only a minor cosmetic issue, it’s not a minor issue when it comes to moisture control.

Under the Dishwasher 

This workhorse appliance is often overlooked as a water damage risk.

Most inspectors turn on and operate the dishwasher in order to look for failures in operation.

If the dishwasher backs up or overflows into the sink, there may be a clogged drain line.  The drain line should be cleaned regularly.

If the dishwasher fails to completely empty after use, the main filter and drain may be clogged.

Find a small leak in the dishwasher water supply hose? It needs to be replaced immediately.

Behind the Refrigerator 

We rarely inspect behind the refrigerator.  But a check-up may prevent messy problems. If the refrigerator has an icemaker, check for damage or disconnection of the supply line.

Moisture behind the refrigerator is a big red flag.  Even if you can diagnose the source of the problem, call out for a professional.  Don’t ignore even a slight leak or kink in the icemaker supply line.

If unidentifiable moldy objects are growing underneath the refrigerator, call them out.  There shouldn’t be any moisture under the refrigerator.

If the model has a drain pan, check the pan for cleanliness, bacterial and other growths.

Beneath the Cooking Range 

Open the bottom drawer to inspect underneath the stove. You may see signs of moisture or mold.

Kitchen Exhaust Fans and Filters 

Fans and filters are small items that play a big role in moisture and mold management. Some fans merely filter and re-circulate air, which does not reduce moisture produced from cooking.

Is the range exhaust filter caked and dirty?

Is the exhaust fan covered with dust?

If there are down-vented indoor grills, check them. They should be clean to ensure the free flow of air.
