Filled-in Arch, An Inappropriate Repair.
An original arched window and decorative stone lintel have
been removed, the arch filled, and a modern window installed.
Not just inappropriate, but boring!

o Use care not to damage the profiles of the moldings with
scraping tools .
o
Sand carefully so as not to blunt the edges of the
moldings.
o
If a heat gun is used, either remove the glass from the
sash or protect it from sudden temperature changes with
gypsum board covered with aluminum foil.
o
If the damaged areas are large, have replica frames or
sashes custom made to match original the sashes and/or
frames.

4.10.3 Metal Windows. If steel windows are basically sound,
it is often more economical to repair and retrofit them than to
replace them. Remove light rust, flaking, and excessive paint;
then prime the exposed metal with a rust-inhibiting primer.
Replace cracked or broken glass and glazing compound, replace
missing screws or fasteners, and clean and lubricate hinges.
(See Figure 4-21.)
