Window Sash Restoration
window sashes to off-site shop facility for chemical dipping
in neutral PH stripper for the removal of paint and glazing
compounds in a controlled environment. 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 EPAs 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.
