On the roof, some repairs were needed to restore the slate shingles. In the cupola, wooden louvres were repaired, the cupola was painted, and a weathervane restored to the top. An existing galvanized sheet metal roof was allowed to remain unchanged.

For the inside of the building there were no photographs or drawings of the earlier periods, and reconstruction was influenced largely by physical evidence disclosed as the interior was systematically dismantled down to the building's outer shell. When woodwork, hardware, plaster and flooring were removed, it was found that much of the framing timber was infested by termites, and had to be replaced. In this process numerous signs of earlier workmanship were revealed.

Beneath the existing tin-plate ceiling was a plastered ceiling and remnants of a painted frieze of red, yellow, blue and green. Behind this ceiling were laths laid over hand-hewn oak rafters. A few of the original hand-split laths and hand-made nails remained in this ceiling. In its reconstruction, the ceiling was furred and replastered without any decoration. No lathwork was found on the side walls, and in the reconstruction fresh plaster was applied directly to the bricks.[165]

The flooring which was removed from the central section of the courtroom sloped from the back (east end) of the room toward the judge's bench (at the west end). Beneath this floor was an older floor of brick. It was not determined whether this brick work had been the original floor of the courtroom or whether another wooden floor had overlaid it prior to the one just removed. In its reconstruction, however, the architect specified that a flat floor of polished pine should be laid over the bricks.[166]

In one part of the main floor the older brick work was allowed to remain exposed. This was in the vicinity of the fireplaces in the two corners of the open area at the rear (east end) of the courtroom. These two fireplaces were reopened and restored and their brickwork was extended to form spacious hearthstones.

The corner fireplaces showed signs of a three-stage evolution. They were originally used as open fireplaces. Holes in the brickwork above them suggested, however, that at some later time the open fireplaces were replaced by wood-burning or coal-burning stoves standing on the brick hearths with their stovepipes fitted into the chimneys. Finally, when the stoves were replaced by central heating and hot water radiators, the entire fireplace wall was sealed with brick and plastered over. In their restoration the corner fireplaces were reopened and refurbished as they were thought to have appeared in their original condition.

As the side walls were cleared of plaster, they showed signs of staircases from the ground level to the balcony along the north as well as the south side of the courtroom. Thus when the stairs along the south wall were replaced, a similar set of stairs was built and installed on the north side of the courtroom. No dates for the original installation or removal of these staircases were determined, and it was presumed that the dual staircases were part of the original design of the courthouse.

A more difficult puzzle was presented by a series of holes in the outer wall aligned at the level of the balcony and about the size used for beams. Speculation by the architect suggested that these holes might have been intended for use in extending the balcony along three sides of the courtroom instead of merely along the back end, or in covering the entire room and creating a full second story for the courthouse. No determination of their use was made, and they were disregarded in the reconstruction of the courtroom.
