Window trim, sills and banding: where stucco leaks, and where it looks best
Windows are where a stucco wall leaks and where it looks finished. A sloped sill with a drip edge, a sealed jamb and a flashed head keep water out; a surround and a band give the elevation proportion. We do both at once, on new work or as an upgrade to a house that already has stucco.
Owners with leaks or stains at windows, and owners who want a plain stucco house to look designed. What you get
Every opening sealed and flashed properly, with surrounds, sills and bands in the profile you chose. Where

What goes around a window
Each opening is five details done by hand. Missing any one of them is how a wall gets wet.
- Head flashing
A metal or membrane flashing over the window that sends water out over the face of the wall, not behind it.
- Jambs
The sides of the opening finished and sealed to the window frame with a backer rod and a compatible sealant.
- Sloped sill
A sill that falls away from the window, with a drip edge underneath so water drops clear instead of running down the wall.
- Surround
The decorative frame around the opening, in EPS, meshed into the wall.
- Bands
Horizontal bands between floors and under eaves, sloped on top and dripped underneath like a sill.
How a window tells you it is leaking
Dark marks at the bottom corners of a window mean the sill or the jamb joint is passing water.
Sealant that has shrunk, split or pulled off the frame has stopped working.
A sill with no slope holds water against the window. Snow sits on it all winter.
The finish lifting below an opening is water that came in at the window and ran down.
Why a plain wall looks unfinished
A stucco elevation with bare openings reads as a box. The same wall with sills, surrounds and a band between floors reads as a house someone designed. The profiles are small, the effect is not, and because they are EPS meshed into the wall they add almost no weight and no maintenance.
On an existing house this is one of the best-value upgrades we do: a day or two of work, every opening resealed while we are there, and the house looks new from the street. On new work we set the profiles out with you from the elevations so the lines land where the architect meant them to.
What moves the number on window work
Every job is quoted after we see the wall. These are the things that move the number.
- Number and size of openings
Priced per opening, with large or arched windows taking longer.
- Repair or upgrade
Resealing and resloping existing sills, or new surrounds on top.
- Profiles
Stock or custom EPS, and the size of the surround and band.
- Height and access
Upper floors from scaffold or a lift.
- Finish
Matching the wall, or a contrasting trim colour.

What our customers say
Window trim, sills and banding questions
Can you fix leaking windows without redoing the wall?
Often, yes. Resealing, reflashing and resloping the sills solves most window leaks. If water has already damaged the wall below, that section is repaired too.
Will new surrounds look added on?
Not when they are meshed into the wall and finished with it. They look like they were always there.
Do bands need slopes?
Yes. A flat-topped band is a shelf for water and snow. Ours are sloped on top with a drip underneath.
Can you do this on a brick house?
Surrounds and bands can be added to brick, and we seal the openings the same way.
Is the work insured and warrantied?
Yes. Stucco & Co carries $5 million liability insurance and WSIB coverage, and every job comes with a one-year warranty on our work.
