EIFS Maintenance: What to Check on Your House Every Year

Most of what we write is about EIFS that has already gone wrong: the wet readings, the soft sheathing, and the repair-or-remediate decision. This one is for the other group. Your wall is dry, or it was corrected a few years ago, and you’d like to keep it that way.

The good news is that EIFS maintenance isn’t complicated. Water almost never comes through the open face of the wall. It comes in at the details: joints, corners, and anything that goes through the cladding. So keeping EIFS healthy mostly comes down to watching those details and fixing small things while they’re still small.

Here’s the walk-around we’d do on our own house.

First, know what kind of wall you have

Maintenance matters on any EIFS home, but it matters most on a barrier (face-sealed) system. Most EIFS on the Cape Fear coast from about 1985 to 2005 is barrier EIFS. It’s designed to stop all water at the outer skin, and it has no drainage path behind it. If water gets past a failed joint, it sits against the sheathing and has nowhere to go. We explain why that design struggles here in why EIFS fails on the Cape Fear coast.

If your wall was remediated with a drainable EIFS, you have more margin, because water that gets in has a way back out. The same details still deserve a look.

The yearly walk-around

Pick a dry day, walk every side of the house, and bring a phone so you can photograph anything you’re unsure about. Here’s where to look.

Sealant joints at windows and doors

This is the big one. Where EIFS meets a window or door frame, there should be a continuous bead of sealant. Sealant ages. It shrinks, cracks, and pulls away from one side of the joint. Look for:

• Gaps or splits in the bead
• Sealant that has pulled away from the frame or the EIFS edge
• Sections that are missing or were never there
• Hard, chalky sealant that no longer gives when you press it with a fingernail

A failed bead at a window is one of the most common ways water gets into these walls, and it’s one of the cheapest things to fix early. When you reseal, have it done properly: old sealant out, joint cleaned, backer rod where it’s needed, and a sealant compatible with EIFS. A fresh bead smeared over a failed one doesn’t seal anything.

Roof-to-wall corners and kickout flashing

Anywhere a roof edge butts into a wall, like over a garage or a porch, look at the bottom end of that roofline. There should be a kickout flashing, a small bent piece of metal that throws water from the gutter line away from the wall. If it’s missing, too short, or bent back flat, water runs straight down into the wall at that corner.

This is the single most common entry point we find on the Cape Fear coast. A kickout costs very little. The rot it prevents doesn’t. Our guide to kickout flashing shows what a correct one looks like.

Decks, railings, and anything bolted through

Deck ledgers, railing posts, light fixtures, hose bibs, dryer vents, satellite mounts, and cable entries all go through the cladding. Each one is a hole that needs a seal. Look for gaps around them, cracked sealant, and staining underneath. Pay attention to anything added after the house was built. A cable installer’s drill hole with no seal is an easy way for water to get in.

The bottom of the wall

EIFS should stop short of the ground, the driveway, and roof surfaces, not run down into them. Where it touches soil, mulch, or pavement, it can wick moisture up into the wall. Check that landscaping hasn’t built up against the base over the years, and that sprinklers aren’t hitting the wall every morning. Pull mulch back, and aim the heads away from the house.

Cracks, dents, and soft spots

Small cracks and impact damage in the finish are worth noting and patching, especially near windows and corners. A spot that feels soft or spongy when you press it, a stain bleeding through, or trim that gives under your hand is a different matter. That can mean moisture behind the board. Don’t patch over it. Get it looked at.

What not to do

• Don’t pressure-wash it hard. A high-pressure wand aimed at joints and edges can force water behind the cladding and damage the finish. If the wall needs cleaning, use low pressure and a cleaner suitable for EIFS, and keep the spray off the sealant joints.
• Don’t caulk everything shut. Sealing joints that are supposed to stay sealed is good. Smearing sealant over weeps, drainage gaps, or the bottom edge of a drainable system blocks water from getting out.
• Don’t let a contractor drill through the wall without a plan to seal it. That goes for new lights, cameras, and anything else mounted on the cladding.

How often to have it inspected

A homeowner walk-around catches the obvious things. It can’t tell you what’s going on inside the wall. That takes a moisture inspection, meter and probe readings at the high-risk details, read by a qualified EIFS inspector. As we note in our buying guide, any EIFS home benefits from a re-inspection every three years or so. A new leak at a window or a cracked bead is cheap to fix early and expensive to fix late. It also makes sense after a big storm season, or before you list the house.

When you get the report back, how to read your EIFS moisture report explains what the numbers mean.

When maintenance isn’t enough

Maintenance keeps a sound wall sound. It doesn’t dry out a wall that’s already wet. If readings come back elevated in one or two spots, a targeted EIFS repair usually handles it. That means opening the area, replacing what rotted, and correcting the detail that let water in. If water shows up across several unrelated areas, the honest answer may be full remediation. The readings decide, not how the wall looks from the driveway.

The short version

• Walk the house once a year and look at the details, not the open wall.
• Window and door sealant, kickouts, penetrations, and the base of the wall are where water gets in.
• Reseal properly, keep sprinklers and mulch off the wall, and go easy with the pressure washer.
• Have a moisture inspection every few years, because your eyes can’t see inside the wall.
