Custom and renovated homes in areas like Cachet, Devil's Elbow, Unionville and the Markham side of Thornhill often mix stone, brick and a smooth stucco look. That finish is not always what it seems. Our Kaizen Real Estate Team is one of the teams Markham luxury buyers trust with due diligence, so here is how to look at it calmly.

Three Finishes That Look Alike

Why Face Sealed EIFS Can Cause Trouble

As Building Science Corporation explains, face sealed EIFS has no drainage path. It depends on perfect sealant joints, and in practice water gets in at joints and penetrations, especially around windows. Wood framing and sheathing are sensitive to moisture, and when wetting outpaces drying, mould and rot can follow.

Drainable EIFS was developed to fix this, with a drainage space, a drainage plane, flashings and weep openings. A well detailed drainable system can perform well.

Where Problems Usually Start

• Around windows and sliding doors, especially at the bottom corners.
• Where decks, balconies and railings attach to the wall.
• Where the roof meets the wall, and at parapets.
• At vents, lights, hose bibs and other penetrations.
• At cracks that start at window corners and reveals.
• Near the ground, where the finish should stop above grade.

Woodpeckers sometimes peck holes in foam based finishes, especially near trees and green space. Small holes still let water in, so note them during a showing.

How to Inspect a Stucco Look Home

1. Ask the seller what the system is, who installed it, and for any warranty or invoices.
2. Tap the wall. Hard coat stucco sounds solid; EIFS sounds and feels hollower and softer.
3. Look for weep openings or a starter track at the bottom of the wall, a sign of a drainable system.
4. Hire an inspector who offers moisture testing for EIFS, not only a general inspection.
5. Check inside under windows for stains, soft drywall or musty smells.
6. Make your offer conditional on that specialist inspection.

Resale: Brick and Stone vs Stucco

Many Markham buyers are comfortable with brick and stone because they know how these materials age. A stucco look home can sell well when the owner can show what system it is, its condition and its history. Uncertainty is what hurts value. If you are selling, a recent moisture inspection and repair records give buyers confidence. Our pre market repairs guide explains what to fix first.

If Repairs Are Needed

Small issues, such as failed sealant or a few damaged areas, can often be repaired. Widespread moisture damage behind face sealed EIFS can mean removing sections, repairing the sheathing and framing, and installing a drainable system. Get written quotes from cladding specialists during your condition period and use them in negotiation. For other common issues in older homes, see our guide on aluminum wiring, Poly B and ice dams.
