James Hardie Fiber Cement Siding in Bath, Maine

Census estimates put Bath's median home built around 1938, with about 58 percent of the housing predating 1940 and roughly 67 percent predating 1960, the oldest housing profile of any town in this service area. Bath's sea-captains' houses and worker cottages from the height of the Bath Iron Works and wooden shipbuilding era make up a large share of the city's stock, many carrying original wood clapboard behind one or more later layers of siding. Outside the historic core, Bath's newer neighborhoods, built through the mid-to-late 20th century, hold a smaller share of more ordinary capes and ranches.

The tidal Kennebec River runs directly past downtown Bath, and river weather, wind, fog and occasional storm surge, affects houses close to the water more than those set back on higher ground. Winters bring the usual Maine freeze-thaw cycling and a real snow load, and Bath's older, less-insulated 19th-century housing is especially prone to ice damming at the eaves during a hard winter. Bath sits a few miles up the Kennebec from open water, so it takes less direct ocean salt spray than a town right on the Atlantic, but river humidity and wind still matter for exterior materials, especially near the waterfront and Bath Iron Works.

Building permits in Bath go through the Code Enforcement Office at 55 Front Street, covering siding, roofing, window and deck work for the whole city. Because so much of Bath's core falls within the Bath Historic District, exterior modifications to buildings inside the district require Planning Board review, though the city notes that review is often completed administratively within about three days rather than requiring a full public hearing. Part of Bath's sewer system uses combined sewers that can overflow during heavy rain, a factor mainly relevant to site and drainage work rather than siding, roofing, window or deck permitting directly, but it does mean the city pays close attention to stormwater management on any project that changes how water sheds off a property.

Fiber cement is a mix of cement, sand and cellulose fiber pressed into planks, shingles and panels. It does not rot, insects do not eat it, it will not burn, and factory-applied finishes hold color far longer than site-painted wood. It is heavier and more exacting to install than vinyl, which is exactly why installation quality shows. The Back Cove home on this site was re-sided with a complete James Hardie package of wood-grain plank.

• Walls are stripped, repaired and wrapped, with flashing at every opening and roof-to-wall joint.
• Boards are cut with dust-controlled tools and fastened to the manufacturer's nailing schedule.
• Required clearances are held above roofs, decks and grade so the ends never sit in water or snow.
• Butt joints get flashing behind them, and cut ends are sealed or primed as the manufacturer specifies.
• Trim, caulk lines and touch-up are finished so the pre-finished color stays uniform.
