Visual Chimney Inspection — Exterior and Interior
Walk the roof or use binoculars to check: cap presence and condition, crown cracking, mortar joint recession on visible courses, flashing condition at roofline, and any efflorescence on exterior brick. Inside: check firebox for water staining, debris, or tile fragments. Document with photos. This turnover inspection catches problems before the next tenant moves in.
Professional Chimney Inspection (If Fireplace in Active Use)
NFPA 211 recommends annual inspection for chimneys in use. For rental fireplaces that tenants actively use, annual professional inspection confirms the chimney is safe and identifies any maintenance needs while they are still minor. The inspection report creates a dated record of chimney condition — important documentation if a condition is ever disputed.
Chimney Cleaning (If Wood-Burning Fireplace in Active Use)
Creosote and debris accumulation in a wood-burning chimney should be professionally cleaned every 1–2 years of active use. For a rental property where fireplace use is unknown or moderate, every-other-year cleaning is a practical interval. Combined with inspection at the same visit, this is efficient scheduling.
Chimney Waterproofing Sealant Re-Treatment
Professional-grade penetrating sealant applied to all masonry faces and crown. Water-drop absorption test at inspection will indicate when sealant has depleted — if the masonry absorbs a water drop within 2–3 seconds, re-treatment is due. Treatment on schedule prevents mortar joint erosion from accelerating between cycles.
Tuckpointing, Crown Repair, Cap Replacement
Performed when inspection identifies the condition — not on a fixed schedule, but addressed before the next waterproofing cycle. Tuckpointing eroded joints, sealing crown cracks, and replacing a failed or missing cap at the time of identification prevents these conditions from progressing into more costly structural issues by the next inspection interval.
