        ![]() Figure 4-19. 
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.)
