When You’re Installing (Not Replacing) a Cap

This page is for homeowners who:

• Have a chimney with **no cap at all** (common in homes built pre-1985)
• Are **adding a cap as a preventative upgrade** (animal entry, water intrusion, debris)
• Just had a **prefab chase cover fail** and need a full new top
• Want to **upgrade from a builder-grade cap** to a real-spec cap

If you’re replacing an existing damaged cap, see our Cap Replacement Cost page.

5 Cost Factors

1. Whether you have a cap currently

Adding a first-ever cap to an open flue requires accurate measurement and sometimes a small mounting bracket. Same price as replacement.

2. Material grade

304 stainless: $189-$-+. 316 stainless: $269-$-+. Copper: $449-$-+.

3. Number of flues

Single-flue is the cheapest. Multi-flue requires a fabricated cover spanning all flues — adds $100-$-+.

4. Chase type — masonry vs. prefab

Masonry chimneys (brick) take a slip-on or mortared cap. Prefab chimneys (Heatilator, Majestic, Superior — about 31% of DFW homes) often need a full chase cover, which is the most expensive option ($449-$-+).

5. Roof access

2-story DFW chases with 9/12+ pitches need harness setup — adds $40-$-+.

Tier-by-Tier Pricing

| Tier | Description | DFW price |

|—|—|—|

| Single-flue 304 stainless | Standard, 1-story | $189-$-+ |

| Single-flue 316 stainless | Premium grade | $269-$-+ |

| Multi-flue stainless | 2-flue fabricated | $329-$-+ |

| Full prefab chase cover | Sheet-metal top replacement | $449-$-+ |

| Copper cap | Premium aesthetic | $449-$-+ |

| 2-story access | Add to any tier | +$40-$-+ |

| Animal cleanout (if uncapped) | Required pre-install | +$89-$-+ |

Common Add-Ons

• **Damper top-seal install** instead of standard cap — $329-$-+ (combines cap + damper function in one piece, eliminates cold-air drop)
• **Spark arrestor screen upgrade** — included free on all stainless caps
• **Crown sealant** — $89-$-+ (recommended if hairline cracks present)
• **Crown rebuild** — $349-$-+ (required if crown is fully failed; new cap won’t seal otherwise)
• **5-year extended workmanship warranty** — included free

Why Cap Installation Matters in DFW

Three reasons DFW homes need caps more than the U.S. average:

1. Storm activity — high wind and hail mean uncapped flues take in debris and damage.

2. Wildlife — chimney swifts (federally protected May-Aug), raccoons, squirrels, and birds will nest in any uncapped flue. We extract 60+ animal nests per spring season.

3. Rain volume — DFW gets 38-42 inches/year of rain; uncapped flues let water down the entire chimney, accelerating crown and firebox damage.

A $249 cap installed today prevents $1,500-$-+ in water damage repairs over the next decade.

FAQ

DFW homes built pre-1985 frequently were built without caps — code didn’t require them. Modern best practice is to cap every flue.

60-90 minutes onsite for a single-flue. 2-3 hours for a full prefab chase cover.

We don’t install in active rain or in winds over 25 mph for safety. Install gets rescheduled to next dry day.

We measure onsite. Single-flue caps are typically 8×8, 8×13, or 13×13. Custom sizes available.

A standard cap doesn’t fully seal — for that, upgrade to a damper top-seal ($329-$-+).

No — if the chimney is uncapped and animals are present, removal is a separate $89-$-+ add-on per visit.
