TL;DR — Real Waterproofing Numbers

Waterproofing a chimney in DFW in 2026 runs $389 to $889, fully applied:

• **$389-$-+** — standard single-story chimney, 80-150 sq ft of brick face
• **$549-$-+** — two-story chimney or premium product spec
• **$729-$-+** — three-story / oversized / premium ChimneySaver Cream-grade product

DFW median PCE waterproofing job in 2025: $489.

Every PCE waterproofing carries a 10-year manufacturer warranty from the chemistry vendor (ChimneySaver / Saver Systems / equivalent) and our PCE workmanship warranty.

Why Waterproofing — The Numbers

A typical DFW masonry chimney absorbs water through its brick face. Brick is porous; mortar joints are even more so. Across 38-42 inches of annual rain, plus 15-25 freeze-thaw cycles, that absorbed water:

• Causes **brick spalling** (face pops off) — $589-$-+ to repair per occurrence
• Accelerates **mortar joint failure** — $389-$-+ in tuckpointing within 5-10 years
• Damages the **crown** from below — $349-$-+ to rebuild
• Rusts the **damper and firebox** — $400-$-+ in damage
• Stains interior walls and ceilings near the chimney chase — variable cost

A $489 waterproofing application creates a vapor-permeable barrier that stops 95%+ of water absorption while still allowing the chimney to breathe (release internal moisture from the firebox combustion). The application doubles the life of any tuckpointing or crown rebuild done before it.

5 Cost Factors

1. Square footage of chimney face

Standard 1-story chimney: 80-150 sq ft. 2-story: 200-300 sq ft. 3-story Highland Park / Preston Hollow estate: 400-700 sq ft.

2. Product grade

ChimneySaver Water Repellent (standard): included at base pricing. ChimneySaver Cream (premium, deeper penetration, 10-year warranty): +$100-$-+.

3. Access and roof pitch

1-story easy access: included. Multi-story with steep pitch: +$100-$-+.

4. Pre-treatment requirements

If the masonry is mossy, dirty, or efflorescence-stained, pressure cleaning before sealer adds $89-$-+.

5. Bundle pricing

Bundling waterproofing with tuckpointing or crown rebuild typically saves 8-15% vs. waterproofing alone later.

Tier-by-Tier Pricing — DFW 2026

| Tier | Description | DFW price |

|—|—|—|

| Standard 1-story | 80-150 sq ft, ChimneySaver Water Repellent | $389-$-+ |

| 2-story standard | 200-300 sq ft | $549-$-+ |

| 3-story or premium product | 400+ sq ft or ChimneySaver Cream | $729-$-+ |

| Pre-treatment cleaning | Pressure clean before sealer | +$89-$-+ |

| Premium product upgrade | ChimneySaver Cream w/ 10-yr warranty | +$100-$-+ |

| Bundle w/ tuckpoint or crown | Discount applied | 8-15% off |

Common Add-Ons / Bundles

• **Tuckpointing first** — required if mortar joints are open; sealing un-pointed joints traps water inside
• **Crown sealant or rebuild** — bundle for combined water-defense system
• **Cap upgrade** — caps + waterproofing together = top-down water defense
• **Annual re-inspection** — included free for 24 months post-application
• **Bundle: tuckpoint + crown + waterproof + cap** — 12-18% off itemized

What “Vapor-Permeable” Actually Means

Old-style waterproofing products were silicone-based “paint-on” sealers that trapped moisture inside the brick — accelerating spalling. Modern vapor-permeable products (silane/siloxane chemistry) penetrate the brick pores and form a hydrophobic layer inside the brick, while still allowing internal moisture vapor to escape. This is the only acceptable waterproofing for a chimney; anything else causes more damage than it prevents.

We use ChimneySaver Water Repellent (silane/siloxane) as standard and ChimneySaver Cream for premium / 10-year warranty applications. Never silicone, never elastomeric paint.

DFW Climate Context

DFW chimneys take the worst of three climate stressors:

1. High summer heat (100°F+ for 30-60 days) drives any absorbed water deep into the masonry

2. Heavy rain events (38-42 inches annually, often in concentrated storms) saturate brick repeatedly

3. Freeze-thaw cycles (15-25 events per year) expand and contract the absorbed water, fracturing brick from the inside

Waterproofing is not a luxury upgrade in DFW — it’s the highest-ROI maintenance investment a chimney owner can make.

What’s Included in Our Quote

• Onsite inspection of masonry condition
• Pre-treatment cleaning if needed (separate line item)
• Two-coat saturation application of vapor-permeable sealer
• Wall, roof, and surrounding-area protection during application
• Cleanup
• Photo before/during/after
• 10-year manufacturer warranty (ChimneySaver)
• 5-year PCE workmanship warranty
• Free re-inspection at 24 months

Watch Out For

• **”Sealing” with elastomeric paint or silicone** — traps moisture, causes spalling. Never accept this.
• **Single-coat applications** — proper waterproofing requires two-coat saturation. Single-coat is half-spec.
• **Sealing un-pointed mortar** — if joints are open, sealing without tuckpointing first traps water in the joint.
• **No manufacturer warranty** — real ChimneySaver applications come with a registered warranty.

A real DFW waterproofing application starts at $389 and uses vapor-permeable chemistry only.

FAQ

ChimneySaver Water Repellent: 7-10 years. ChimneySaver Cream: 10+ years (with 10-yr warranty).

3-5 hours onsite for a standard chimney. Brick is dry to the touch in 4-8 hours; full cure 7 days.

No — vapor-permeable sealers are clear and don’t darken or shine the brick.

After. Tuckpoint first (so water can’t get into open joints), then waterproof to lock the system out.

Yes — best ROI is on chimneys 5-15 years old, before water damage starts. Prevention is 10x cheaper than repair.

No — it’s preventative maintenance, not damage repair. Insurance covers the damage that waterproofing prevents.
