Other projects undertaken and financed by the Priestley Chapel Associates included replastering, reglazing, repainting, replacing of old wiring, and repointing brickwork. However, problems remained and in 1991 the PCA hired architect Richard Williams of Wilkes Barre to make a comprehensive review of what was needed to finish the rejuvenation. The review was completed in 1992 and a multi-phased program projected to cost $36,000 was adopted. Stimulus was provided with the rebirth of a Unitarian congregation in Northumberland, the Unitarian Universalist Congregation of the Susquehanna Valley (UUCSV),  which came about chiefly as the result  of efforts by Rev. John Morgan, who, in 1990, was engaged by the Joseph Priestley District of the UUA to revive Unitarianism and Universalism in northeast Pennsylvania.

By the end of the summer of 1995 the rejuvenation program was successfully completed, under budget by about $1000. With the aid of a $10,000 grant from the Joseph Priestley District Chalice Lighters (through the UUCSV) sufficient funds had been raised. A low brick wall, which appeared to be the original curbing, was removed, new walks and railings were placed, and the property landscaped. The exterior trim was painted and the bricks sealed.  Inside was more dramatic.

The entire building was cleaned out of the accumulation of 160 years. In the cellar a gas furnace replaced the coal furnace and the coal bin removed.  Concealed cold-air returns improved the warm air flow and the chimney was equipped with a stainless steel flu liner.  In the attic the ceiling supports were reinforced to retard the perennial cracking of the plaster down the center, and additional circulation was provided. The stained glass windows were removed for cleaning and refurbishing. All cracks in the plaster were repaired, the entire interior, including the pews, was repainted, and the floor was refinished and recarpeted.  An unobtrusive ceiling fan was installed to provide cooling on warm days and to distribute heat on cool days.  Later the building was air-conditioned.

When the shutters were removed to facilitate painting, it was virtually unanimous that the chapel was dramatically brighter and more cheerful, so they were stored in the cellar and not put back up.  When all else was done, as with the 1910-1912 remodeling, the stained glass windows were put back in with protective Plexiglas sashes on the outside. The event was celebrated with a large, full-color photo on page 1 of The Daily Item for June 9, 1995.
