Restore historic steel or hollow metal window sashes and frames in place, unless sashes or frames are to receive new components pieces because of damage, delamination, or severe rusting. Remove existing finish paint coatings, glazing compounds, and exterior sealants to bare metal using neutral PH based chemical paint stripper.

As of April 22, 2010, a new law governing renovations that contain lead paint became effective. Aimed at protecting against lead-based paint hazards, the EPA’s new rule applies anytime a lead paint surface is disturbed by renovation or painting projects, including repairs, maintenance, electrical, plumbing, carpentry, demolition, and window restoration / replacement. The rule also requires renovation firms to be certified by the EPA, and that they assign at least one EPA Certified Renovator to the job to ensure that lead-safe work practice standards are observed. Leeds Clark Inc. is an "EPA Certified Firm", and both Tom & Chris Clark are "EPA Certified Renovators". Go to www.epa.gov/lead for additional information about the new EPA rule and other Lead Programs. Leeds Clark is not a licensed or insured asbestos abatement contractor.
