Water Test Guide

Suburban Basement will request a water test if the repairs you received require it.

The “water test” or “water leak test” helps to ensure that the repair was effective. Some cracks require a touch-up to completely seal the area sufficiently.

This is especially important if you intend to finish or refinish the repaired area. When possible, we ask for the test to be performed 2 days in a row to properly emulate a heavy rain.


    Do Not Perform a Water Test the same day as the repair 



  1. Note the “before” condition of the area. It might help to take a picture.
  2. Place a garden hose outside, directly adjacent to the repaired area.
  3. Run the water for about 30 minutes.
  4. Check the repaired area for leaks or changes.
  5. If a Leak is found complete step 5, if not skip to step 6.
    • Note the time it took for the leak to appear after starting the test.
    • Feel the wall to see if it “feels” damp or just looks that way.
    • Mark the wall (chalk, crayons or painters tape work well for this).
    • Take a picture or note the change you see (pictures are most helpful).
  6. Report your findings to Suburban Basement

Drywall Removal for Assessments

Having a finished basement is a nice feature for your home. It increases your floor space and adds value. When a leak is found in a finished basement it can be very frustrating for the homeowner. The fact is that this nice feature you have added to your home makes it difficult to find the source of the leak.

Most often when a leak is found in a finished basement it appears to the homeowner that the leak is coming up through the floor. Whenever we hear this issue from a homeowner, we ask;

  1. Is your basement finished?
  2. Is the water showing up where the drywall meets the floor?

The reason being that the true cause is most often a crack, rod hole or some other issue that is allowing the water to enter through the foundation wall. Once the water comes through the wall of the foundation it travels down that wall and comes out under the drywall.

What about Inspection Camera’s and Moisture Meters?

These items may be helpful but the truth of the matter is that they can be unreliable.

Inspection camera’s do not always give a clear picture of the foundation wall that a technician would be looking for. The picture can be obscured by dust, electrical wires, foam board and insulation. This can cause errors in estimates and require additional costs once the wall is opened up.

Moisture meters often give false readings as they are meant to detect moisture and both the foundation wall and drywall are porous and hold certain amounts of moisture naturally.

What if I don’t want to remove the drywall?

Suburban Basement does not like asking homeowners to remove drywall. We know the time and cost to remove and replace it. However we are dedicated to providing effective and honest solutions to homeowner’s waterproofing needs. This means that we will want to see what is happening behind that drywall. As expected homeowners do not like hearing that removing the drywall may be needed as well. One item that we like to remind homeowners of is that if the leak truly is coming in behind the drywall that moisture is building up on the back side of the wall and could lead to mold growth. Therefore they will likely want to replace that drywall.

Drywall Removal Guide

To make things as easy and smooth as possible we have put together a diagram that shows how and where to start in the removal of the drywall.

  1. Start at the source where the water is located
  2. Cut a 4 foot x 4 foot square
  3. Look for evidence of the leak
  4. Follow the evidence and let it guide you
  5. Continue to cut and remove drywall as you follow the evidence until you locate the source
  6. When the source is located be sure to expose the area so that repairs can be made

We advise all of our homeowner that they can contact us during this process if they have questions. They can send us pictures if they are unsure that enough area is exposed or any other questions they may have. We will do our best to make the process as painless as possible.
