Almost all of the stucco EIFS that has been built today has a sewage system installed in it that will allow moisture to drain off. In fact, the new ones are of premium quality and high durability. Unfortunately, similar to every other development project, contractors required over several years and billions of pounds to find out the best way to use it. Due to this reason, tens of millions of previously built EIFS stucco structures around the state will come in contact with major hazards.

Have you taken a moment to wonder if the house you are going to purchase soon has EIFS? How about the house you are already residing in? What kind of cladding materials does it have? Does moisture get stuck at the back of the coating? Well, the only way to find all the answers out is through moisture testing!

You should perform the testing at least once a year. We recommend using these two different moisture meters :

1) A non-invading meter – Its job is to only scan thoroughly over the walls without interrupting the EIFS elastic fibers.

2) A meter similar to a probe – What shall it do? It will breach through the EIFS lamina and indicate humidity levels of materials that are in touch with the probes.

Such inspections can only be carried out by a specialist who is trained in water leakage examinations at EIFS.

What is the main purpose of the repairs? To prevent infiltration of water! Renovations must be performed where there is evidence of excessive water or degradation of the material’s tensile strength. When you can detect structural damage anywhere, you will immediately have to remove the impacts of the water interference. Otherwise, these areas may cause further corrosion of wooden furniture near to the walls. A recent discovery denotes that once the water leakage source has been detected, as long as the material is damp but unharmed, the substratum will dry out on its own over the time.

Water Instrusion

A frequently asked question related to this is that, how does water get in behind EIFS? Let us answer the question for you. Water gets in through/between underestimated places of your house such as your windows, doors, gable vents, etc and a wide range of flashing and building details.

Moisture penetration often happens when certain parts and different sensitive areas, such as caulk joints, are neglected for repairs. Discovering the incidence of water ingress is critical since water may penetrate behind the insulation material and inflict harm into the vulnerable sealant, and in some cases the wooden concrete structures.  

If you are thinking that your wall will dry off instantly, you are mistaken! It all relies on the environment and the general composition of the wall frame! When water ingress keeps being undetected by you in a given environment, it can increase to levels that are sufficiently significant to inflict serious degradation. Believe us, the only way to reduce and avoid these losses is early detection! The earlier you can carry out the moisture testing, the better will it be for you!  

Water entrance position is not only troublesome to detect, but only trying to inspect with your naked eyes can give you misleading results. You can not always identify the corrosion to the substratum and concrete structures behind the external wall cladding just with the help of your eyes. If water penetration goes unnoticed, you will be in great trouble later. Moreover, if you sit idle and allow it to keep deteriorating further,  the damage can become even more extreme over the time! That’s where the importance of moisture testing comes into play – it’s better to be safe than sorry isn’t it?

Moisture: an enemy of your EIFS siding

In the late 1980s, EIFS had become quite prominent, and guess what? It is still being widely used as an external coating medium nowadays in many parts of the world. The stucco system gives a classy design to a building, with the additional perk of covering the home with better insulation by retaining warmth. But still many complications started to occur momentarily due to various implementation issues and structural flaws.

Initially EIFS stucco has been built to construct a protective barrier across the house. This is called a “face-secured” installation. This was built to maintain the warmth inside the house.

As the product aged, however, people began to see cracking and wearing of the cladding. This presented areas where moisture could breach the sealed system and seep behind the stucco.

However, over the time as more people gradually started implementing it in their homes, something unexpected became prevalent. People started noticing fractures and cracks in the coating surface. It exposed areas where the insulated framework could be penetrated by moisture and trickle at the back of the render.

Since the material was crafted to be completely enclosed, it could do nothing if the water could successfully get in, in any way. It is similar to having zero drainage system. Water will remain behind the brickwork, deteriorating the walls down and your wooden furniture over time. Not only that, it will result in unpleasant fungus issues between the components as well. Hence, people started being compelled to cut off the siding from their homes and to make massive and expensive repairs.

What should you do now?

We suggest you to hire someone professional, well-experienced and trained enough to carry out moisture inspections with EIFS. When? They should be hired to perform close inspections within six months after the repair. The replacement efficiency will then be tested as part of the annual overall house humidity report.

How will you understand if the repairing you did was not profitable?

High concentrations of humidity will be spotted and the procedure of repair should be assessed for the cause of malfunction. Keep yourself updated with another inspection after further repairs until you get to a point where the level of moisture is appropriate.
