Insert or full-frame replacement?
Use existing-frame condition, water-management details and surrounding finishes to guide the installation approach.
At a glance
Full frame
Exposes the rough opening so interfaces and hidden conditions can be addressed.
Decision
Existing frame condition and water management matter more than convenience alone.
The useful decision
Use existing-frame condition, water-management details and surrounding finishes to guide the installation approach.
What an insert preserves
An insert generally retains more of the existing frame and surrounding finishes, but reduces the clear opening and depends on sound existing conditions.
When full-frame deserves consideration
A full-frame approach exposes more of the opening and can better address concealed deterioration or water-management details, but usually involves more finish work.
What to document
Photograph interior and exterior conditions, measure the opening, note cladding and trim, and have the installer confirm the appropriate method on site.
Bring this to the conversation
Project checklist
- Photograph exterior cladding, trim and sill conditions.
- Look for staining, softness, movement or previous sealant repairs.
- Record whether interior finishes must remain undisturbed.
- Have the installer confirm the final method after site review.
Avoid assumptions
Questions worth answering
- Is the retained frame sound, square and dry?
- How will the new unit connect to the drainage plane?
- What interior and exterior finishing is included?
Before final selection
Discuss your opening
Confirm the exact product, current documentation, applicable codes and project conditions with the appropriate project professionals and Morrison team.
