The answer is no. New construction, also known as nail fin and retrofit, are just different ways of approaching the same issue—replacement of windows or doors.
In retrofit, the existing framing, flashing, water-resistant sheathing and other components are deemed to be in good shape. Only the window or door unit is removed and replaced with a new one. In the case of windows, the new product comes with an external nail fin (a metal sheath) secured to the building. Precise measurements are taken to ensure that the new windows or doors fit into the space allotted.
New construction is usually used when a home, apartment or condominium complex is being built. However, in circumstances such as when an opening has to be expanded or there is wood rot or other conditions, a contractor may suggest using the nail fin method. As this procedure requires cutting way the framework and rebuilding it, there can be external damage if it is not performed by a licensed professional. As Bel-Air Exteriors, we are experts in doing this type of work and have a contractor’s license to back it up.
After speaking with the homeowner or multi-family housing manager, our technicians at Bel-Air Exteriors can help you determine which choice best fits your job. Before making this determination, we'll consider several factors, including the condition of the existing window or door frame, project timing and budget.
