What is synthetic stucco?
Synthetic stucco homes are common in Gainesville. In fact, when you see stucco homes throughout Florida and other parts of the United States, there’s a good chance they are not traditional stucco homes but are synthetic stucco homes, also known as EIFS. If you would like to be informed about the latest news regarding interior design and architecture we recommend you to visit this website archute.com you will find a lot of great information there.
The simplest explanation I could find about synthetic stucco, also known as EIFS, comes from an article about synthetic stucco on about.com:
“EIFS stands for Exterior Insulation and Finish Systems. The product is also called synthetic stucco, and refers to a multi-layered exterior finish that’s been used in European construction since shortly after World War II, when contractors found it to be a good repair choice for buildings damaged during the war. The majority of repairs to European buildings were to structures constructed of stone, concrete, brick, or other similar, durable materials.”
According to the article, EIFS was introduced to the United States in 1969 by Dryvit Systems. Prized for its superior insulating properties, cost-effectiveness, and its ability to be designed into a variety of architectural styles, EIFS was primarily used on commercial buildings in the United States until the early 1980’s, when it was introduced into the residential building market. Arriving at the decision to move means you have asked yourself and answered a lot of questions. Choosing the new place you want to move to is primary, but it involves many other queries like how close it is to a school or how it will affect your work. The questions do not stop coming until you have actually settled into your new home. There are still many details you have to sort out before and during moving day, you can visit this website to make from moving to a new house a nice experience.
In addition to Dryvit, EIFS manufacturers include Acrocrete (BASF), Parex, and Sto.
Synthetic stucco/EIFS was designed as a “barrier system,” meaning that its success is dependent upon no moisture ever getting into the building envelope. To remain completely moisture free, all construction steps have to be followed, all flashings have to be properly installed, all windows and aluminium bifold doors have to be properly caulked, etc.
“the properties of the product that make it a good insulator (designed to keep air from moving from the inside to the outside) also make it a poor drainer/ventilator (does not allow water that gets in to get back out).”
Problems with EIFS and Synthetic Stucco
Problems surfaced in the residential market with synthetic stucco/EIFS because, unlike commercial buildings, residential homes are not framed out with concrete or steel. Instead the synthetic stucco/EIFS cladding is generally applied over plywood framing, and moisture intrusion combined with plywood do not a very healthy pair make. Adverse effects of moisture intrusion into an EIFS home can include accumulation of moisture in the wall cavity, structural damage, mold growth, and termite or carpenter ant infestation. According to the International Risk Management Institute Inc. (IRMI),
In the mid-1990’s, 209 EIFS homes in Wilmington, NC were discovered to have chronic moisture problems, resulting in serious mold and structural issues. According to an article on EIFS by Florida Master Home Inspectors,
Lawsuits were filed and the EIFS manufacturer, Dryvit Systems, settled with the homeowners. Similar problems with synthetic stucco/EIFS have been reported in Canada as well as throughout the United States including Alabama, Colorado, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Mississippi, Missouri, New Jersey, New York, North Dakota, Ohio, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Utah, Virginia, and Washington.
EIFS homes – insurance issues
“From an insurance standpoint, finding coverage for homes built using EIFS can be quite difficult. The product is highly susceptible to moisture and if not properly maintained, homeowners could find themselves with mold issues, which is the primary area of concern for insurance providers,” says Bryan Williams, an insurance advisor with McGriff-Williams Insurance in Gainesville.
Drainable EIFS and industry turnaround
Several states outlawed non-drainable EIFS for home building, including North Carolina, New Jersey, and Oregon.
In 1997 drainable EIFS was introduced into the market by EIFS manufacturers. Drainable EIFS systems give moisture that gets behind the cladding a way to escape, greatly lessening the potential for structural and mold problems in synthetic stucco homes.
When synthetic stucco manufacturers created drainable EIFS systems, the industry began to make a turnaround.
Joseph Lstiburek, a forensic engineer, was one of the first people to sound the alarm over the problems created by the non-drainable EIFS cladding. Since the product’s redesign into a drainable system, Lstiburek is one of the biggest proponents of using EIFS in residential construction.
Synthetic stucco homes – tips for homeowners
A thorough inspection of the home’s exterior by a structural engineer or certified EIFS inspector will help the homeowner to determine whether the EIFS system is drainable or not drainable, whether there are currently water intrusion problems, and what steps homeowners should take to maintain their home.
The Exterior Design Institute maintains a list of qualified EIFS inspectors by state. According to its website,
“The Exterior Design Institute is a non-profit organization founded for the purpose of training and certifying Building Envelope and EIFS Inspectors and Moisture Analysts to promote quality control within the construction industry.”
Repairs to synthetic stucco homes should be performed by contractors well-versed in the use, maintenance, and application of EIFS.
“Reliable contractors have training certificates or qualification certificates from major EIFS manufacturers. Reliable contractors may also hold an EIFSmart certification from AWCI,” says Dennis Rose, a certified EIFS inspector from Ocala and an EIFS Instructor with the Exterior Design Institute.
The EIFSmart contractors national registry is another resource you can use to find EIFS contractors listed by state.
Synthetic stucco homes – tips for homebuyers
Gary W. Jackson, a North Carolina attorney who deals with cases involving construction defects, suggested the following tips for homebuyers considering the purchase of a synthetic stucco home in a 2004 article in REALTOR ® Magazine:
Insist on obtaining all relevant, available information about a stucco home from the seller:
- Is the system traditional stucco or is it EIFS?
- Have repairs been performed?
- Have moisture readings or other inspections been conducted? Obtain an EIFS inspection on the home (in addition to a regular home inspection).
- Obtain an EIFS inspection on the home (in addition to a regular home inspection).

Synthetic stucco and EIFS – Note to Readers
I am not an expert in construction or synthetic stucco or EIFS. This article is a review of industry literature on the topic of synthetic stucco/EIFS homes. Questions about synthetic stucco/EIFS homes should be directed to an industry professional, who is, I repeat, not me.
