Stucco repair, caulking, refinishing and parging for Thornhill houses on both sides of Yonge Street, with our published prices and a fixed quote in writing after a free visit.
Thornhill is two cities, and Yonge Street is the line
Thornhill has no city hall of its own. Yonge Street is the boundary between Vaughan and Markham, and the area is usually taken to run from Steeles Avenue up to Highway 7, between Dufferin Street and Highway 404 (Thornhill, Ontario). For stucco work, the side of Yonge your house sits on decides which City you deal with.
Vaughan side
West of Yonge Street
Building permits and any heritage question go to the City of Vaughan. A crack repair or a refinish in the same colour rarely needs either, but taking a wall off and re-cladding it is a different job.
The rest of the city is on our Vaughan stucco page.
Markham side
East of Yonge Street
Thornhill is one of Markham's four heritage conservation districts. In a district, the City asks owners of every property to get approval for exterior alterations, and to keep original wall cladding (Markham heritage districts).
Permits go through Markham's ePLAN portal. The rest of the city is on our Markham stucco page.
Three things to check about your address before the visit
- Which side of YongeYour tax bill or the City's property lookup says Vaughan or Markham. A Thornhill postal code doesn't tell you.
- Inside the district or notA heritage district has a boundary on the City's map, and a Thornhill mailing address doesn't put you inside it. The City's heritage staff can tell you from the address.
- Repair or new wallFilling cracks and patching to match is upkeep. Taking stucco off, cladding over brick or adding foam changes the outside of the house, and that's when a City may want to see it first.
For a Markham address, Building Standards answer at 905.475.4858 or buildingstandards@markham.ca, Monday to Friday, 8:30 to 4:30 (Markham building permits).
What you can see on the wall, and what it costs
Find the line that looks like your wall. Each price is the one already published on our service pages, and the fixed price comes in writing after a free visit.
Per crack, opened up, filled and finished to match. More on the stucco repair page.
A typical repair, depending on what's behind the damage once it's open.
The wet section cut back to sound board and rebuilt. Water usually got in above the stain.
Old sealant cut out and replaced. Our caulking page puts a whole house at $800 to $2,500.
Refinishing a full elevation, so the repairs and the old wall end up one colour.
A small parging repair. A full foundation is $1,500 to $3,000 on the parging page.
Two finished walls from our photo file
Most of Thornhill grew after the 1960s, as Toronto spread north across Steeles. These two walls are from our own jobs elsewhere in the GTA, shown so you can see the finish.
Brick and stucco on the same house
Many Thornhill houses are mixed: brick on most of the wall, stucco on a gable or an upper storey. On those houses the stucco and the roofline are usually done together, because the top edge of the wall is where water gets in.
- Stucco on a gable end meets the soffit and the eavestrough, so we look at both before pricing. Our soffit and eavestrough work can go in the same visit.
- Where stucco meets brick there's a joint, and that joint is often the failure, not the stucco.
- Covering more of the brick is a bigger decision. The prep that decides whether it lasts is on our stucco over brick page, and on the Markham side the City may want to see it first.
