I’ve got a window replacement job coming up on my own house. I’m weighing the pros & cons of sash replacements, ie Marvin TiltPacs versus complete window replacements with Andersen TiltWash units.
The details of the job are about 26 units involved, all standard sizes, most of which are in aluminum siding. The siding is getting replaced but that’s another project. The rest of the units are in brick. The originals are Morgan Red Seals which was basically a shop window from about 30 years ago. Their frames are in very good shape but installation wasn’t always square. Storm windows were added. Screens are long gone so I’ll need to measure & have a whole house worth made. At first glance, the TiltPacs are a much easier install. The work is done from the inside with minimal disruption. The sash can be ordered primed but not prefinished. The Andersens require outside work but include screens. The also have a white prefinish option, which I’d use. They have no brick mould, unlike the Morgans. The Andersen’s nailing flange would lie under where the brick mould on the old units was. The old siding is butted & caulked to the trim with no J-mould used. Outside trim is TBD. I can either add brick mould or temporary 5/4×2 until the new siding goes in. I’ll most likely go Hardi & then I might upgrade to 5/4×4. All jambs are standard so no extensions would be needed if I go full replacement.
