EIFS vs. Traditional Stucco: Differences and General Cost Notes
EIFS stands for exterior insulation and finish system, often called synthetic stucco. It looks like stucco but is built differently, and that affects how it is repaired. This guide explains the difference in plain terms and gives general cost notes. For traditional stucco repair prices see the stucco repair cost guide.
How they differ
| Traditional cement stucco | EIFS | |
|---|---|---|
| Structure | Cement plaster applied in coats over metal lath and paper | Foam insulation board covered by a mesh-reinforced base coat and a thin finish coat |
| Weight and surface | Hard, heavy cement surface | Lighter, often softer surface that dents more easily |
| Insulation | Not insulating on its own | The foam board adds some insulation |
| Common repair issue | Cracks, water behind the wall | Water getting in at joints, windows and damaged spots |
Both systems depend on good flashing around windows, doors and rooflines. In either case, water that gets behind the surface can cause damage that is not visible until the wall is opened.
Cost notes
Exact prices vary widely, and few California stucco contractors publish them. As a rough planning idea only:
- Small EIFS patches and sealing work can fall in a range similar to a stucco patch, roughly the same few hundred to few thousand dollars.
- Repairing EIFS that has moisture damage behind it can cost much more, because the foam, base coat and sometimes the sheathing under it must be opened up and rebuilt.
- Replacing a whole wall or house with new EIFS or new cement stucco is a large job priced per square foot. See the re-stucco cost guide for general ranges.
None of these are quotes. Ask for a written scope that says what will be opened up and how it will be sealed.
How to tell which you have
Tap the wall. Cement stucco sounds hard and solid. EIFS often sounds hollow and can feel slightly soft. A contractor can identify it, and they can also take a small test cut. If you are not sure, ask before comparing quotes, because a company that works only on cement stucco may not be the right one for an EIFS wall.
Questions to ask
- Do you work on EIFS as well as cement stucco, and can you describe a recent EIFS repair?
- How will you check for moisture behind the wall?
- How will windows, joints and flashing be sealed?
- Is the contractor licensed? Check at cslb.ca.gov.
