Why stucco changes the job
Replacing a window means cutting into the wall and disturbing the existing measures that control air and water. BC Housing notes that the type of cladding, the style of replacement window and the rain exposure all affect how much wall work is needed. In a stucco home, the finish around each opening is part of the plan.
BC Housing adds that trim at the window perimeter can help integrate new windows with the existing wall and limit disruption to it. Ask what trim is proposed, how it will look against the stucco and who handles any stucco patching.
Insert or full-frame replacement
Natural Resources Canada describes two methods. An insert fits a new window into the existing frame. It is usually less expensive and disturbs less of the surrounding wall and trim, but should be done only if the old frame has not deteriorated and is properly sealed and insulated. A complete tear-out removes the old frame too, allowing an airtight, insulated seal to the rough opening.
Ask how water will be managed
NRCan calls exterior caulking the last and weakest defence against rain. Properly applied flashing and a properly detailed drainage plane are the best defence. BC Housing adds that openings exposed to rain need suitable products and installation methods.
Mention any leaks or staining you have seen. BC Housing notes that water appearing at a window may come from the adjacent wall, the roof or the joint between window and wall, and a replacement may not fix a source elsewhere.
Questions to ask each contractor
- Method: insert or tear-out at each opening, and why?
- Stucco and trim: what will be disturbed, and who finishes the wall?
- Water control: how will flashing be handled at the top, sides and bottom of each window?
- Hidden conditions: how will damage found after removal be documented and priced?
- Background: relevant experience, references, a WorkSafeBC clearance letter and proof of general liability insurance.
BC Housing notes that, depending on a home’s age, materials including stucco may contain asbestos. If you are unsure, have a specialist sample it before work begins rather than testing it yourself.
Compare quotes on the same scope
BC Housing notes that the extent of wall work is key to the scope and cost of a window replacement. Two prices can describe different jobs if one includes stucco finishing, trim and flashing and the other does not. Ask for the method, wall work and exclusions in writing, along with product and installation warranties.
