KSP Construction provides disciplined restoration of stained glass assemblies and historic steel windows for architecturally significant buildings throughout Connecticut and New York. Their work begins with careful assessment of original frames, glazing, and masonry to determine appropriate conservation, repair, or selective replacement strategies. Stained glass panels are documented, releaded where required, repaired with compatible glass, and reinstalled with proper structural support and weather protection. Steel sash are dismantled, cleaned, stabilized, and re-glazed to correct air and water infiltration while preserving original sightlines and profiles. Window lintels and adjacent substrates are addressed where deterioration has compromised performance. Fabrication, inspection, and installation are executed with measured craftsmanship, returning aging windows to service without sacrificing authenticity, proportion, or material integrity.
