01General notesA-110.1

What EIFS is, and what it isn’t

EIFS stands for Exterior Insulation and Finish System. From the sheathing out, a modern system is an air and water-resistive barrier, an adhesive, rigid foam insulation board, a base coat with fiberglass mesh embedded in it, and a textured acrylic finish. From the street it looks like stucco. Underneath it is a different wall: lighter, insulated on the outside, and able to take curves, reveals and deep trim that would be heavy and slow to build in cement.

People call it synthetic stucco, or just foam. The name matters less than the generation. EIFS installed before the mid-1990s was usually a barrier system, which counted on its outer skin and its sealant joints to stop every drop of rain. Today’s systems are drainage EIFS: a membrane behind the foam, and a path that lets any water that gets past the face run down and out at the base. Drainage EIFS is the only kind we install.

If your building has traditional cement stucco instead, the repair approach is different, and our stucco repair and restoration page covers that side. Not sure which one you have? The comparison below usually settles it, and a few photos with your estimate request let us confirm it before we price anything.

Drainage EIFS, barrier EIFS and traditional stucco

Three walls that can look the same from the sidewalk. What separates them is what happens to the water that gets past the surface, because every wall takes on some.

04DetailA-110.4

The systems we install: Sto and Master Wall

We install complete systems from Sto and Master Wall: barrier, adhesive, board, mesh, base coat and finish from one manufacturer, built to that manufacturer’s published details. We don’t pair one maker’s base coat with another’s finish. Keeping every layer in one system means the products were tested together and every detail on the wall comes out of the same book.

StoTherm® ci pairs Sto’s fluid-applied StoGuard® air and water barrier with EPS board set in vertical adhesive ribbons. Master Wall® Rollershield® uses a roll-applied barrier and vertical-channel adhesive. Both are drainage systems. The choice usually comes down to the specification, the substrate and the finish you want. If an architect has already specified one, we build to the spec. If not, we’ll tell you which we’d use on your wall and why.

You can see finished commercial entries, multifamily walls and residences in our project gallery.

  • Fluid-applied air and water barrier, with sheathing joints and rough openings detailed first
  • Vertical adhesive ribbons or channels that leave water a path to drain
  • Continuous EPS insulation with staggered, rasped-flat joints
  • Fiberglass mesh in the base coat, with heavier mesh in impact zones
  • Acrylic finish in your texture and color, with aesthetic reveals where the design calls for them
  • Proper terminations at the base and at openings, and sealant joints at windows, doors and other materials

New walls, additions, re-clads and commercial work

Drainage EIFS suits more building types than people expect. These are the four we’re asked about most.

  1. 01New

    New construction

    On a new home or building, EIFS goes on once the sheathing and windows are in. We coordinate with the window installer and the roofer so every flashing laps the right way, and we read the architect’s details before the first board goes up, not after.

  2. 02Add-on

    Additions

    An addition has to meet the existing wall with no visible seam and no leak at the joint. We tie the new barrier into the old wall, match texture and color, and put an expansion joint where the two structures meet, because they will move differently.

  3. 03Re-clad

    Re-clads

    Old barrier EIFS, tired stucco or worn-out siding can come off and be replaced with drainage EIFS. A re-clad is also the cleanest chance to add continuous insulation, fix window flashing and correct whatever caused the old wall’s problems.

  4. 04Commercial

    Commercial & mid-rise

    Entries, storefronts, offices and multifamily buildings. Bigger walls bring lifts or scaffolding, phasing around tenants and customers, and coordination with other trades and the property manager. The wall details stay the same at every scale.

06ScheduleA-110.6

EIFS repair: where it usually goes wrong

Most EIFS problems start at the edges of the wall, not in the middle of it. Here’s where we look first, and how each one gets fixed.

  1. 01

    Holes and impact damage

    Mowers, ladders, hail and woodpeckers puncture the finish and base coat. Each hole is cut back to clean edges, filled with matching foam, re-meshed and blended. Left open, a puncture lets water reach the foam and the sheathing behind it.

  2. 02

    Failed sealant joints

    The sealant around windows, doors, vents and fixtures hardens and pulls away over the years. We cut it out, clean and prime the edges, set new backer rod and re-seal with a sealant the system’s manufacturer lists for that joint.

  3. 03

    Windows and doors

    A stain under a window usually started at the window itself: no sill pan, a gap in the flashing, or sealant asked to do a flashing’s job. Patching the face without fixing the opening just moves the leak a few inches.

  4. 04

    Roof-to-wall kick-outs

    Where a roof edge runs into a wall, a kick-out flashing has to turn the water into the gutter. When it’s missing, water pours down the face of the wall and into it. It’s one of the most common sources of hidden damage on EIFS houses.

  5. 05

    Terminations at grade and decks

    EIFS should stop short of the soil, paving and deck boards, with the foam edge wrapped and sealed. Foam that runs into the ground wicks up water and gives insects a way in. We cut it back to a proper termination.

  6. 06

    Soft spots and delamination

    A wall that sounds hollow, flexes under your hand or bulges may have lost its bond or have wet material behind it. Those areas get opened, the cause found and fixed, and the layers rebuilt from the barrier out.

07NoteA-110.7

Worried about water behind the wall?

Stains below windows, soft spots, bulges or a musty room on an outside wall deserve a closer look. An independent EIFS inspector can probe-test the wall: small holes at the likely leak points, moisture readings, then the holes are sealed. If you’re buying or selling a building with EIFS, get that report first; it comes from someone who isn’t selling the repair. Then send it to us with photos or drawings and we’ll price the fix.

08General notesA-110.8

Re-coating, color changes and trim

Sound EIFS that has faded, chalked or collected dirt doesn’t need to come off. After repairs, the wall is cleaned and re-coated with a finish or coating the system’s manufacturer lists as compatible, usually a breathable acrylic from the same product line. A general-purpose house paint may not bond to the finish, may not let the wall dry the way the system expects, and leaves you with a wall that no manufacturer’s detail covers.

Re-coating is also the time to change the color, or even the texture: a new finish coat can go from a fine sand texture to a coarser one, or the reverse. Our page on coatings for stucco and EIFS covers the color side, and if you’d like to see the building in a new scheme before you commit, we can model it in 3D first.

Cornices, bands, window surrounds and quoins are where EIFS buildings get their character. They’re cut in foam, meshed and finished with the wall, so they read as part of it. Our architectural foam trim page shows the shapes and the details that keep their tops dry.

09General notesA-110.9

Continuous insulation, the energy code and the weather window

Foam on the outside of the framing is continuous insulation. It covers the studs, so heat can’t short-circuit through them the way it does when the insulation sits only between them. Both states build their energy codes on the International Energy Conservation Code, and most Massachusetts cities and towns have also adopted the Stretch code or the stricter Specialized code, which push wall performance further. EIFS is one of the most direct ways to meet those requirements on a new wall or a re-clad. Our Massachusetts service-area page and New Hampshire service-area page explain what the state rules mean for a project.

The materials also have weather limits. Sto and Master Wall both call for air and surface temperatures of at least 40°F while the materials go on and for at least 24 hours after, with protection from rain while the coats dry. In New England that makes spring through fall the main season. When a schedule has to run through winter, the walls can be enclosed and heated to hold the temperature. That adds cost, so it appears as its own line in the price, and we’ll tell you plainly whether it’s worth it or whether waiting for spring makes more sense.

What sets the price of an EIFS job

We don’t publish a price per square foot, because the number that matters is the one for your building. These are the things that move it. With plans or elevations that show dimensions, we measure every wall, opening and trim run from your drawings and price each one.

  • Wall area, and how much of it is broken up by windows, doors and corners
  • New work, re-clad or repair, and how much old cladding has to come off first
  • The system specified and the insulation thickness
  • Foam trim: cornices, bands and surrounds, and how many custom profiles
  • Finish texture, the number of colors and any aesthetic reveals
  • Height and access: ladders, staging, lifts or scaffolding
  • Hidden damage found once the wall is opened up
  • The season, and heated enclosures if the work runs into the cold months

info@kingsofdesigncorp.com
01What is EIFS, and how is it different from stucco?

EIFS is a layered cladding: a water-resistive barrier, foam insulation board, a mesh-reinforced base coat and a thin acrylic finish. Traditional stucco is a thick cement plaster, usually three coats over metal lath, with no insulation. The two can look alike, but EIFS insulates the wall, weighs far less and takes shapes and trim easily, while stucco is harder and more rigid. They fail in different ways, so they’re repaired differently. If you’re not sure which you have, send a few photos with your estimate request and we’ll tell you.

02Is EIFS a bad idea? Does it cause moisture problems?

EIFS earned a bad reputation in the 1990s. Many homes were clad in barrier systems with no drainage behind the foam, and they trapped water at windows and rotted the sheathing. The industry and the building codes responded with drainage EIFS: a membrane behind the board and a path for water to escape. Installed to the manufacturer’s details, with proper flashing at windows, roof edges and decks, drainage EIFS is a sound wall. Most problems today trace back to missing flashing or failed sealant, not to the system itself.

03How long does EIFS last?

With sound details and basic upkeep, decades. The wall assembly itself is durable; what wears out first is the sealant at windows, doors and penetrations, and the finish, which fades and collects dirt. Walls that get their joints renewed and a fresh coating when they start to look tired hold up far longer than walls left alone until a leak shows up inside. If you notice open joints, cracks from window corners or stains, have the wall looked at before the next winter rather than after it.

04How much does EIFS cost per square foot?

We don’t publish a per-square-foot figure, because it can mislead more than it helps. The price depends on wall area and how many openings break it up, the system and insulation thickness, trim and reveals, height and access, how much old cladding comes off, and the season. Send plans or elevations with dimensions and we’ll measure your actual walls from the drawings and send a free written price, usually within 48 hours. No drawings yet? It’s still free: we visit, measure and send the price after the visit.

05Can damaged EIFS be repaired, or does it need to be replaced?

Most damage can be repaired. Punctures, cracks, failed joints and small wet areas are cut out, the cause is fixed, and the layers are rebuilt, textured and coated to blend. Replacement makes sense when moisture damage is widespread, when an old barrier system leaks at opening after opening, or when you want to add insulation and correct the details in one go. We’ll tell you which side of that line your wall is on, and why, before you spend anything.

06How do I know if my EIFS has water damage behind it?

Warning signs include stains or streaks under windows, cracks running from window corners, soft or spongy spots, bulges, open sealant joints, and musty smells or peeling paint inside on exterior walls. None of these prove damage, and a clean-looking wall can still be wet behind. The reliable test is moisture probing by an independent EIFS inspector, who checks the likeliest leak points and maps the readings. We work from that report to plan and price the repairs.

07Can you paint or re-coat EIFS?

Yes. After repairs and cleaning, EIFS can be re-coated to refresh the color or change it. The coating should be one the system’s manufacturer lists as compatible, typically a breathable acrylic finish or coating rather than a general house paint. Sealant joints are replaced in the same visit, since a fresh coat around failing joints doesn’t protect anything. A re-coat can also adjust the texture. If you’d like to preview a new color scheme first, we can produce a 3D rendering of the building.

08Which EIFS systems do you install?

We install complete drainage systems from Sto (StoTherm® ci) and Master Wall (Rollershield®). Every layer comes from the same manufacturer and goes on to that manufacturer’s published details for your substrate. If an architect has specified one of them, we build to the specification. If the choice is open, we’ll recommend a system based on the substrate, the design and the finish you want, and explain the reasoning in the estimate.
