Chimney service quotes are particularly prone to two problems: a low initial price for an “inspection” that’s used as a foot-in-the-door to sell expensive repairs, and quotes for significant repairs (particularly relining) that are provided without adequate documentation of what the inspection actually found. Getting a written quote that specifies the exact work, the exact materials, and the documented basis for the recommendation is the foundation of a fair comparison.

“A chimney quote without an inspection report behind it is a guess. I can’t give a meaningful quote for relining without knowing the chimney dimensions, the liner condition, the appliance specifications, and the access constraints. Any company that quotes a full reline without completing a camera inspection first is either doing it sight unseen or they’ve already decided what they’re going to sell you before they’ve looked.”

Has an inspection been completed before any repair quote is accepted?

Never accept a repair quote — particularly for relining or significant masonry work — without a documented inspection basis. The quote should reference specific findings from a camera inspection. If the company is quoting significant repairs without documentation of what the inspection found, ask why.

Are you getting at least two quotes for significant work?

For any chimney repair costing more than $1,000 — and relining, masonry rebuilding, and significant repair work easily exceed this — getting a second quote from a different WETT-certified company is worth the time. The first thing to compare is whether both companies find the same problem in the camera footage.

Questions About What’s Included

For cleaning: what does the sweep include?

A chimney sweep (cleaning) typically includes removing creosote from the flue, cleaning the smoke shelf and smoke chamber, brushing the firebox, and disposing of the debris. Ask specifically what’s included and whether a Level 1 visual inspection is included alongside the cleaning.

For inspection: what level is included, and what does it cover?

Ask whether the inspection is Level 1 (visual only) or Level 2 (camera). For any inspection you’re using to make a maintenance or repair decision, Level 2 is required. Ask whether footage or a report is included.

For relining: is the liner only, or does the scope include accessories?

A complete relining includes more than the liner itself — the top plate, the chimney cap, insulation (for wood-burning applications), and the connection at the appliance. Ask for a line-item quote that specifies each component.

Ask specifically:
– What liner diameter and gauge is included?
– What stainless steel alloy? (316L for gas/wood; 904L for oil)
– Is a new chimney cap included?
– Is a top plate included?
– Is liner insulation included?
– Who connects the liner to the appliance?

For masonry work: what is the scope in detail?

Masonry repair quotes should specify:
– What mortar type for each area
– What areas are being tuckpointed (linear feet of joints)
– Whether the chimney crown is being patched or replaced
– Whether the chimney cap is being replaced
– Whether flashing is being replaced or repaired

Ask for a line-item breakdown.

Questions About Timing and Disruption

How long will this work take, and when can I use the fireplace afterward?

Ask specifically:
– For cleaning: same-day service, typically 1–2 hours
– For inspection: typically 1–2 hours
– For relining: typically one full day
– For masonry work: depends on scope; mortar joints need cure time before the fireplace can be used

Ask specifically when the fireplace can be safely used after any repair is complete.

Questions About Payment

What is the payment schedule?

For cleaning and inspection: payment at time of service is standard.

For significant repairs (relining, masonry): a deposit of 25–30% at signing to secure materials ordering, with the balance at satisfactory completion. For smaller repairs, payment at completion is standard.

Avoid companies that require full payment upfront for significant repair work.

Questions About Warranty

What warranty do you provide on your work?

For cleaning: no warranty applicable.

For relining: ask what warranty the company provides on the installation workmanship, and what manufacturer warranty the liner itself carries. Stainless steel flexible liners from reputable manufacturers typically carry lifetime limited warranties on the liner material.

For masonry repairs: 1–2 years on tuckpointing workmanship is reasonable; chimney crown replacement should carry at least a 1-year warranty.
