If you have a specific question that is not directly addressed below, feel free to submit it through our contact form and we will be happy to respond as quickly as possible. The first one that comes to people’s minds is What is Stucco? how strong is stucco? is Stucco Heat Resistant?

1. How do I know if my home is finished with a true EIFS?

To find out if your house is finished with a proper EIFS, you can try to carefully tap on it as you would a door.  If it sounds hollow, it is probably an EIFS.  If the sound is more solid in nature, it is likely a plaster stucco product.  In the case that you feel the wall has a very coarse texture, this would be another indicator that a stucco product has been applied.

It is important to note, however, that EIFS coatings can also be applied without insulation directly onto hard sheathing boards, like cement boards.  Rapping on this type of application will also produce a solid sound, similar to stucco.

2. How do I know which manufacturer’s EIFS product is on my home?

It can be difficult to know which brand of EIFS has been installed, as most brands of EIFS look the same.  You can try contacting the general contractor who built the house, or the contractor who has experience on EIFS, if you can obtain their contact information – they may recall which brand of EIFS was installed on your home.  Always is good to verify as it’s a good practice no to rely 100% upon on what is written in the building specifications since they will often mention a certain brand while another brand is actually installed.

3. Can I identify the EIFS brand from its mesh color?

Some brands of EIFS can be identified by the color of the mesh.  Knowing that this may provide a starting point, it is not a reliable determining factor.  Also keep in mind that once the mesh is buried within the basecoat, it will be difficult to determine its color.  If you can see the mesh color, some common identifiers for EIFS brands are:

4. Can I repair an EIFS myself?

EIFS is not a do-it-yourself product.  It is recommended to hire a certified EIFS contractor.

5. The EIFS is leaking. How do I inspect it?

Customarily, the EIFS itself does not leak.  Leaks almost always occur at the edge of the EIFS, either at an opening (such as a window), a penetration (like a deck beam), or at a flashing/sealant joint.  Regarding self-inspection, you can do a quick visual examination for obvious flaws, such as cracks or the lack of caulking, but detailed assessments are best left to professional inspectors.

6. Removing and replacing an EIFS?

When it comes to removing Existing stucco “Demolition”. We look over whether it’s Synthetic with styrofoam insulation or Traditional with multi-layers of cement reinforced with Metal Lath. If it’s Synthetic and there is the need to remove it, we cut away the entire system installed. Including the foam, back to the supporting wall.  The old EIFS cannot be reused.  The supporting wall is then inspected for damage and any required repairs are done and Moisture-proof. This could involve removing studs and/or sheathing, which can be an extensive process.  The new EIFS is then applied over the repaired wall and is blended into the surrounding EIFS, if and as necessary.

7. I have a barrier-type EIFS on my house and would like to add a drainage-type EIFS to it. Is this possible?

Regrettably, it is not possible to add a drainage-type EIFS to an existing barrier-type EIFS.  To add drainage, the existing EIFS would have to be removed and replaced completely with the new drainage-type EIFS.

8. What is the difference between EIFS and Traditional Stucco?

EIFS may come in several different types, but the typical installation includes the substrate, a polystyrene foam board fastened/glued to the substrate, fiberglass reinforcement mesh, a basecoat (usually 1/16 to 1/4 inches thick), and then a finish coat.

On the other hand, stucco is portland cement plaster.  The stucco assembly usually includes a substrate over the framing members with a moisture barrier present, self-furring metal lath, cement plaster basecoat, and lastly a hard-coat finish.  Both systems have advantages and disadvantages.

9. How can I tell if I have the newer drainage-type EIFS?

Drainage-type and barrier-type EIFS look virtually identical from the outside, but you may be able to differentiate them by looking under the horizontal edge of the EIFS where it comes to an end, such as at the top of a window or at the bottom of the wall close to the ground.

A drainage-type EIFS will have some sort of gap, flashing, or a perforated piece of metal or plastic trim, to route water from the drainage cavity to the outside. However, the presence of such a gap is not a foolproof indicator, as some barrier-type EIFS also incorporate this feature.  Cutting through the EIFS to check for building paper between the foam and the sheathing is also not a reliable method, as some barrier-type EIFS also incorporate a paper layer.  The paper alone does not produce a true drainage cavity.

Once again, it would be worthwhile to hire an experienced contractor to inspect the EIFS.

10. My EIFS has dots or spots all over it. What is causing this?

Most of the Cases in residential homes EIFS are installed using fasteners screws. These fasteners consist of a large plastic washer and a metal screw.  The washer sits on top of the EIFS insulation and is covered by the EIFS coatings.  The washer is thus just a fraction of an inch from the outside air.  Since the fastener is made of metal and plastic, the washer will be at a different temperature than the surrounding layer of EIFS insulation.  This temperature disparity means that the EIFS coatings retain a different amount of moisture at the fastener than within the surrounding wall.  This in turn makes the EIFS finish look like it is a different color, hence the wall appears to have dots or spots on its surface.

The dots/spots rarely do any harm and usually disappear as the wall’s temperature becomes more consistent throughout, such as during the middle of the day.  This phenomenon is unavoidable but may be reduced by applying a thick initial EIFS basecoat to even out the temperature of the EIFS surface, thus reducing the dotting effect.

11. How do I repair leaky windows?

If the leak is actually in the interface between the EIFS and the window, a simple solution such as adding caulking to seal the leak will often be effective.  If the leak is coming from the window itself, this sometimes can be repaired with the window in place or the window may need to be replaced entirely (often the case when the window frame is old and rotted).

Removing a window from an EIFS wall can be difficult, as many residential windows use a nail flange to mount the window to the face of the wall sheathing, preventing the window from sliding out of its opening.  It is advisable to hire a professional in these circumstances.

12. Are EIFS repairs visible?

With expert workmanship, repairs will be hard to detect, especially if they extend back to a nearby corner or joint.  Normally, though, the patch will be visible right after it is done.  As the wall ages, the patch blends in and becomes less visible.

13. Can I paint my EIFS?

Yes, you can paint over EIFS treatments in general; however, some EIFS finishes will contain additives that make it difficult for the paint to adhere.  It is best to contact the specific EIFS manufacturer to ask which paints will work on their various finishes.

Luckily, most EIFS formulas are pure acrylic, which means that basic exterior grade acrylic house paints will work just fine.  In any event, it may be wise to perform a small test on an inconspicuous area of the EIFS, letting the paint dry for several days to see if it remains bonded.

Paint is usually applied with a roller on large flat areas of an EIFS while a brush is used in small or intricate areas, such as around windows and in grooves.

14. There is a hole or a depression in my EIFS.

Can it be repaired by applying base coat and finish into the damaged area?

No, simply plugging a hole in the EIFS with basecoat and finish will not be sufficient, as the so-called plug will eventually fall out.  The best way to repair a hole or a depression properly is to cut the EIFS away (back to the substrate) and apply new foam and coatings to the new insulation.  EIFS manufacturers often provide photos/written instructions of how to proceed, but having a professional EIFS contractor perform the repair will ensure the best result.

15. How long does an EIFS last?

The lifecycle of an EIFS system depends on how well it was initially installed and how well it has been maintained over time.  An example of the required maintenance includes replacing the caulking, which will eventually wear out and lose its effectiveness.

There are some older EIFS projects dating back to the 1950s in Europe and to the late 1960s in North America that remain in very good condition today, occasionally requiring just a fresh coat of paint to freshen their appearance.

16. Is there a difference in quality between EIFS brands?

Since each EIFS manufacturer has its own formulation/composition, there will definitely be a difference in quality between the various brands.  Within the product line of a given brand manufacturer, there are often various grades of EIFS as well, with the higher quality grades usually sold at higher price points.  However, the quality of an installed EIFS system is just as dependent, if not more so, on the installer.

17. If I am buying an existing EIFS home should I have an EIFS inspection done?

Yes, it is always a good idea to have an existing EIFS inspected by a professional when you may have concerns about the condition/state of repair of a particular installation.  While an EIFS installation may look fine, most problems are hidden below the surface.  A professional inspection will assess the present value of the installation as it relates to the overall value of the home, and also give the buyer and the seller, as well as realtors and insurance agents, a good level of comfort.

18. We are building a new EIFS home.

What are the most important points that we should consider?

• Have complete drawings and specifications of the EIFS proposed by the home designer
• Carefully follow the EIFS manufacturer’s published design and installation instructions
• Follow the specifications for an EIFS outlined within the local building code requirements
• Hire a qualified and certified EIFS contractor
• Enlist the input/customer service support of the EIFS manufacturer whenever there is any doubt regarding the installation
• Have professional inspections done on the EIFS while it is being installed and again after words

19. Our home is stucco with some EIFS foam shapes on it.

Our insurance agent is appraising the property as if it were an EIFS home. Is this an acceptable practice?

Looking at it From a functional standpoint is considered to be a stucco house if the base walls have a stucco finish. Regardless of any EIFS applied over them as a decorative trim.  In such cases, the EIFS is used simply to enhance the aesthetics of the home and has little effect on the performance of the wall.

20. When is the use of drainage EIFS required?

The use of a drainage-type EIFS is dependent on the local building requirements and is also heavily reliant on the local climate.  It is at the discretion of each homeowner to determine if drainage is a necessary feature in the particular EIFS installation for their home.  Consult with the EIFS manufacturer or local homebuilder for advice pertinent to your specific region.

What are “Toronto” Exterior Insulation Finish Systems (EIFS)?

PUCC, exterior insulation finish systems are both insulation and siding. This definition might bring to mind a home exterior coated in bright pink fiberglass insulation made to look like a cotton candy house you might find at the local fair. However, homes with EIFS can benefit from an unlimited spectrum of colors, textures, and designs.

The exterior insulation finish systems comprise some rigid insulation boards placed on the wall sheathing’s exterior. Exterior insulation finish systems work with several substrates.

Installers covered that rigid polystyrene insulation board with a thin coating of a changed cement base coat, fiberglass reinforcement, and a textured, colored finish coat chosen by the homeowner.

Today, architects and builders looking to offer continuous insulation for homes built in areas with strict energy codes or homes looking to attain specific green building certifications. Some of them are LEED preferred the “Toronto” EIFS Exterior Insulated Finish System in action in 2021.

Exterior Insulated Finish Systems are non-load-bearing and exterior wall cladding systems made up of an insulation board fastened either or to the substrate. They then applied a reinforced base coat over the insulation board before a textured protective finish coat is applied. We know the vast majority of exterior insulation finish systems used by home builders as “EIFS with Drainage.” As we will discuss below, the traditional EIFS Exterior Insulated Finish System had problems with moisture accumulation and leakage. EIFS with drainage, which is the predominant method used by builders and architects today, incorporates specific safeguards to reduce moisture before it enters the wall cavity. See the plan flexibility and aesthetics of EIFS in real life.

EIFS are sustainable, durable, and resilient. Impact-resistant EIFS Exterior Insulation Finish Systems are achievable using industry-standard application practices and products that are very effective and economical. The keys to high impact resistant Exterior Insulation Finish Systems are the same as for any quality construction: good design, firm and definitive specifications, use of the proper products, and proper construction.

Flexibility and efficiency

How Do Flexibility and aesthetic of “Toronto” Exterior Insulation Finish Systems (EIFS) Save Energy in action in 2021?

EIFS are unique because they are the best exterior cladding system for offering thermal control and improved energy efficiency to the home. EIFS is a fundamental aspect of continuous insulation systems. Insulation offers constant protection across all structural members of the house. This insulation alternative aims to eliminate all thermal bridges in the structure, except for fasteners and service openings.

EIFS is the best performing cladding to provide thermal and moisture protection. EIFS with drainage allows homeowners to maximize their energy savings, reducing their household carbon footprint and the home’s environmental impact. Besides offering continuous insulation around the exterior of the house, these exterior cladding systems can also improve the airtightness of the building envelope – one of the most critical elements of energy-efficient home construction. Take a look through the exhaustive best list of EIFS benefits.

EIFS offers a pathway to improve your home’s energy efficiency and thermal performance with no negative health consequences when installed. However, improper installation techniques and older variations of EIFS that did not include specific drainage systems have been shown to lead to serious mold growth. As water and moisture accumulate against the sheathing of your home, mold growth is likely, especially for wood sheathing.

Besides leaching allergens into your home, this mold growth can also decay your structure leading to expensive repairs. Homes with barrier Exterior insulation finish systems in action in 2021 are “prone to moisture intrusion problems even when constructed according to industry standards.

Unlike other cladding types, the design of barrier EIFS does not allow the draining of water that gets behind the system, either through building components (openings in the building envelope for doors, windows, etc.) Or when sealants break down or crack. Depending upon the climate and the wall assembly’s overall make-up, the wall may not dry out. Sustained elevated levels of moisture without adequate drying will cause rot or decay to sheathe and framing. To be presice In addition to the fact that EIFS come in boundless shadings and a wide assortment of surfaces, however, they can likewise be formed into basically any shape or design. If it’s not too much trouble, spend some time in this Project Galleries and investigate some fantastic EIFS Projects!

Benefits Of “Toronto” Exterior Insulation Finish Systems
