Historic Home Maintenance Checklist

Preventive maintenance is the single most cost-effective preservation investment a historic homeowner can make. Most of the major deterioration problems that affect historic homes — structural rot, masonry failure, window deterioration — result from deferred maintenance that allowed small problems to become large ones. This checklist provides a framework for regular inspection and maintenance.

Disclaimer: This checklist is for general guidance only. Specific maintenance needs vary by building, material, and condition. Consult licensed professionals for any work beyond basic cleaning and inspection.

Twice-Yearly Inspection (Spring and Fall)

Roof and Drainage

  • Inspect roof surface for missing, cracked, or curling shingles or tiles
  • Check flashing at chimneys, dormers, valleys, and roof-wall intersections — these are the most common points of water entry
  • Clear gutters and downspouts of debris; ensure downspouts direct water away from the foundation
  • Check for signs of ice damming at eaves (in winter climates)
  • Inspect attic for evidence of water infiltration or condensation

Masonry (Brick, Stone, Mortar)

  • Inspect mortar joints for cracking, crumbling, or erosion — deteriorating mortar allows water entry and should be repointed with lime-based mortar matched to original
  • Check for efflorescence (white salt deposits on masonry surface) — indicates water moving through masonry
  • Inspect for spalling brick (surface breaking away) — often caused by hard modern mortar or freeze-thaw cycles
  • Check chimney caps and crowns; inspect chimney mortar

Exterior Woodwork and Paint

  • Inspect all painted wood surfaces for peeling, cracking, or bare areas — address promptly to prevent moisture entry
  • Check porch columns, balusters, and railings for rot at bases and joints (where water collects)
  • Inspect window sills and sill nosings — these are primary rot locations on wood windows
  • Check caulking at window and door frames; recaulk as needed with paintable caulk
  • Inspect exterior trim at eaves, rakes, and cornices

Foundation and Grading

  • Walk the perimeter and check that grade slopes away from the foundation on all sides
  • Inspect exposed foundation (if visible) for cracking, movement, or spalling
  • Check basement or crawl space for water infiltration, staining, or efflorescence
  • Ensure crawl space vents are clear and functioning (or sealed if the crawl space is conditioned)

Annual Tasks

Windows

  • Re-glaze any windows with failing glazing compound (the putty that holds the glass in the sash) — failing glazing allows moisture to enter the wood sash
  • Inspect and replace weatherstripping as needed
  • Lubricate window hardware (sash lifts, locks, pulleys)
  • Touch up or repaint window sash and sills as needed

Interior

  • Inspect plaster ceilings and walls for new cracking — hairline cracks are generally stable; wider or growing cracks may indicate movement
  • Check hardwood floors for gaps, cupping, or raised boards that may indicate moisture changes
  • Inspect accessible plumbing for corrosion or leaks
  • Test smoke and CO detectors; inspect the electrical panel for any tripping breakers or visible issues

Vegetation Management

  • Trim trees and shrubs away from the building — vegetation in contact with exterior surfaces traps moisture and accelerates deterioration
  • Remove any vines growing on exterior walls — they trap moisture and can damage mortar joints
  • Keep firewood and soil away from wood siding and porch bases

Five-Year and Long-Term Planning

Some maintenance items require periodic attention on a longer cycle:

  • Full exterior paint cycle: most historic homes with wood exteriors need a full repaint every 7–12 years depending on exposure and paint quality
  • Roof replacement: varies by material; have the roof professionally assessed as it approaches the typical replacement age for its material type
  • Repointing assessment: have masonry joints professionally assessed every 10–15 years
  • Chimney inspection: have working fireplaces inspected by a certified chimney sweep every 1–3 years
