Window trim and interior window sill installation in Ottawa — FixItAll Handyman Services
Bare drywall edges, gaps around the window frame, or an unfinished opening can make the room look incomplete.
These issues often show up after a new window install, basement finishing, or drywall work.
I install interior window trim and wooden window sills neatly and accurately.
That includes fitting jamb extensions, leveling the sill, and casing the window for clean lines.
Nail holes are filled and seams are smoothly caulked so the finish looks tight and consistent.
I provide window trim and sill installation across Ottawa and nearby areas.
What’s included (scope): installing a solid wooden sill, fitting jamb boards/jamb extensions on all sides, adding clean casing, securing everything tightly, filling nail holes, and neat caulking.
When this service is needed: after new windows (including basement/egress), when drywall returns are exposed, when existing trim is damaged, or when you want a more finished, modern interior look.
How the work runs: I check the opening and reveal, confirm the trim profile and layout, level and fasten the sill, fit and secure jamb pieces, install casing, then finish with filling and caulking for a durable, paint-ready result.
• This service is for interior trim, jamb extensions, and interior sills. Window replacement, exterior flashing, and water-leak diagnostics are not included unless agreed separately.
• If the window opening is out of square or walls are significantly uneven, small visual gaps can remain; I aim for the cleanest practical fit and confirm expectations before finishing.
• If there is active water intrusion, soft framing, or structural damage, that should be addressed first (repairs can be quoted separately).
