Porter Chimney LLC IN Westwood, MA








Annual Care
Soot & Creosote
Rotary Mechanical Sweeping
High-torque nylon whipping chains remove combustible Stage 3 creosote while HEPA containment vacuums trap microscopic particulate, guaranteeing pristine living room carpets throughout the sweep.
Diagnostic Scoping
Level-Two Video Flue Scoping
Our articulating 360-degree cameras travel the entire vertical run of your chimney flue to spot hidden terra cotta fractures, missing mortar joints, and internal smoke chamber voids.
Weather Shielding
Crown Sealing & Mortar Wash
Elastomeric waterproof membranes protect concrete chimney crowns from winter water absorption, stopping expanding ice crystals from cracking your top exterior brick courses.
Draft Control
Top-Mount Damper Installation
Cast-aluminum silicone-gasket dampers seal the flue rim directly at roof height, preventing costly conditioned room heat loss and halting downdrafts when the firebox sits idle.


Structural Craft
Hearth Restoration & Masonry
Stainless Steel Flue Relining
Continuous titanium-stabilized stainless liners replace decayed clay tiles, creating a perfectly sealed exhaust pathway with custom-parged insulation blankets.
Custom Lead Counter-Flashing
Hand-folded step flashing interlocked into saw-cut brick mortar joints stops chronic roof leaks where siding meets external chimney masonry.
Historic Brick Repointing & Rebuilds
We rake back deteriorated sand-lime mortar joints and hand-tool fresh, breathable mortar formulated to match historic Westwood architecture. Rebuilding weathered chimney shoulders ensures long-term structural integrity through severe seasonal storms.

Itemized Diagnostic Report
Every homeowner receives an NFPA 211 evaluation report containing captured video stills, clear code observations, and prioritized repair recommendations.
We inspect flashing seals, spark arrestors, brick spalling, and crown integrity to detect moisture penetration before beginning internal diagnostics.
Triple-layer protective canvas drop cloths and commercial HEPA negative-air collectors isolate your hearth area to prevent airborne soot distribution.
We pass high-output optical cameras through the full flue passage to check draft performance, creosote deposits, and clearance to combustible framing.
Same-week appointments available across Westwood, Dedham, Norwood, and Walpole.
