EIFS Moisture Testing

EIFS repair and EIFS moisture testing goes hand in hand

I think it is about time we included EIFS moisture testing as a service in our everyday services, as it only makes sense to find out where the moisture is and where it came from before we even start any repairs. Till this point we had been calling in 3rd party inspectors and waiting for the results and then taking over from there and correcting all their findings anyway. The truth of the matter is that you really cannot simply read a book, go out and buy an expensive moisture EIFS Moisture Testingmeter and think you are going to be proficient at finding moisture behind the synthetic stucco. It takes years of particle experience in the field. We have been applying Exterior Insulation and Finish System for over 27 years and have been focused on synthetic stucco repairs full time for over 5 years. There is absolutely no one more qualified to do your Exterior Insulation and Finish System moisture test, bottom line. Knowing where to look for moisture intrusion and what to look for is half the battle, but water is a funny thing. I have seen on numerous occasions water infiltrating the the system from one area and running down a metal stud or I-beam up to 30 or 40 feet away and causing damage. The usual suspects for moisture intrusion are other products not the synthetic stucco itself. The flashing will fail or was not done right in the first place or the caulking will begin to crack and let moisture in around the doors and windows. Whether, the roof copping or the sealant failed it is usually due to one of two things someone didn’t do it right to begin with or someone did not maintain it for years. We have done a ton of repairs over the years and we have seen it all. We know exactly what the problem is as soon as we look at it nine times out of ten. Just knowing there is moisture behind the wall and what the percentage reading from a meter is, is really not good enough to begin the repairs or even estimate how much it is going to cost to fix it. You have to know where the moisture came from and how you are going to prevent it from returning. For this reason we carry a moisture reader with us on all our repair jobs. Moisture testing goes hand in hand with a visual inspection. Having the equipment is a great help in determining the problems but there is nothing that can replace 28 years of hands on experience. A good EIFS inspection utilizes testing equipment and years of experience in the field.  

EIFS (Exterior Insulation and Finish System) is also known as Dryvit™ or Synthetic Stucco.

New Home owner with EIFS – Question

My question as a new homeowner with EIFS, should I avoid all together
putting any kind of nails or screws in the EIFS for fear it will allow
moisture in. I am thinking of hanging some planters, a piece of
grillwork, and a hose holder. Is there a special way to insert a screw
or nail to prevent introduction of moisture? Thank you.

That is a very good question Joyce, and you are right to that the nail or screw hole will allow moisture and over time can even cause some real problems. What you will need to do first is to get some screws long enough to go through the EIFS system and into the sub-straight. It is important to make sure each screw hole is sealed with silicon caulk. The reason I say silicon caulk is that the silicon caulk will not eat away at the foam like other caulks will.

With that all being said I would like to tell you about a conversation I had the other day with a rep from STO about a cool way to do this process. How it works is that you get some PVC tubing and use it for a mounting bracket. First you will use a drill to cut a hole of the desired diameter and push the piece of PVC with a small amount of adhesive (once again make sure you use a foam friendly adhesive like PL Premium)  into the hole making sure the tubing is flush with the EIFS System. Now you can run your screw in your home made hole and fill with caulk. With this system if the nail or screw were to fall out of need to be replace you can simply pull out the caulk and replace it all nice and clean. Having the PVC will help with the heavy things like planters as well you have to keep in mind that there is only foam back there. I really like this idea. I feel this process would work great for filling the holes on store fronts after the side has been removed.
