A masonry repair estimate tells you exactly what a contractor intends to do, in what way, with what materials, and under what conditions. A complete estimate gives you enough information to hold the contractor to a specific standard of work. An incomplete one gives them room to do less.
The difference between a $2,200 tuckpointing job and a $2,800 job is often not skill or quality. It is scope definition. One contractor removed mortar to 1/2-inch depth. The other removed to 3/4 inch. One used Type S mortar on soft historic brick. The other specified lime-based mortar matched to the original. Identical-looking estimates from two contractors can represent entirely different work. Reading an estimate correctly lets you compare what is actually being proposed, not just the number at the bottom.
This is a step-by-step guide to reading every section of a masonry repair estimate before you sign anything.
What a Complete Masonry Repair Estimate Must Contain
A written masonry repair estimate should cover eight elements. If any are missing, ask for them in writing before signing. A contractor who cannot or will not provide this information is telling you something about how they work.
Itemized scope by elevation or section. The estimate should break down the work by location: front facade, north wall, chimney (all four sides), attached garage. A single lump-sum line for all masonry does not constitute scope. You cannot compare bids that are not broken down the same way, and you cannot verify completion if the scope was never defined.
Linear footage or area measurement. Tuckpointing is priced per linear foot in the Chicagoland market, ranging from $8 to $25 per linear foot depending on access, mortar specification, and joint condition. The estimate should name the total linear footage per elevation or section. Without footage, a low per-foot rate can produce a high total if the contractor measured more generously.
Mortar type, explicitly named. Not “matching mortar” or “appropriate mortar.” The specific ASTM C270 designation: Type N (minimum compressive strength of 750 PSI), Type S (minimum 1,800 PSI), or a lime-based specification for historic brick. This is the single most technically important item on the estimate. Using the wrong mortar type on the wrong brick produces damage more expensive to correct than the original deterioration. For more on why this matters, see Lime vs. Portland Cement Mortar: Which Does Your Home Need.
Joint removal depth. BIA Technical Note 7B specifies a minimum joint removal depth of 3/4 inch for tuckpointing. This should appear on the estimate. Shallow removal, typically anything under 1/2 inch, does not provide the mechanical bond depth new mortar needs to perform.
Brick count if replacement is included. If the scope includes brick replacement, an approximate brick count and a statement about sourcing (salvage brick matched to original, or new brick matched by manufacturer record) should appear. In the Chicagoland market, a single brick replacement runs $50 to $150; a section of 10 to 30 bricks runs $500 to $2,000.
Access method. Ladder access on a two-story front facade produces different work quality than scaffolding. The estimate should state how upper elevations will be accessed. Scaffolding is required on tall walls, wide facades, and any surface where precise joint work from a ladder would compromise quality.
Timeline. Start date, estimated duration, and weather contingencies. Tuckpointing requires temperatures above 40 degrees Fahrenheit for 48 hours after application. A project starting in late October in Chicagoland carries different completion certainty than one starting in July.
Payment schedule and warranty. What is due at signing, what is due at completion, and what the warranty covers. Standard terms are discussed below.
Verify a contractor’s Illinois license through the IDFPR license lookup before signing. The Mason Contractors Association of America maintains the industry standards professional contractors reference when structuring their scopes.
How Scope Differs by Housing Stock: Historic Winnetka vs. Builder-Grade Northbrook
The itemized scope on a legitimate estimate varies significantly based on the age and construction type of your home. A historic Winnetka home from the 1920s through 1940s and a builder-grade Northbrook home from the 1960s through 1980s are fundamentally different repair scenarios.
Winnetka, 1920s to 1940s. Winnetka’s median home was built in 1942. The common brick type is soft Chicago common brick, and the original mortar is Type N lime-based. These homes were built with mortar intentionally softer than the brick so seasonal movement travels through the joint rather than the brick face. NPS Preservation Brief 2 governs the standard of care for soft historic masonry: lime mortar or mortar softer than the brick is the required specification, not a preference.
A complete estimate for a Winnetka home of this era includes additional line items that a standard estimate would not:
- Mortar analysis to determine original lime-to-Portland ratio and aggregate composition
- Custom lime mortar batch specification (color, texture, and compressive strength matched to original)
- Joint profile matching notation (Winnetka homes often used V-joint or grapevine tooling that standard concave tooling destroys)
- Portland cement mortar removal if previous incorrect repairs are present, noted as a separate scope item with its own footage
- Scaffolding almost certainly required for tall Georgian, Colonial Revival, or Tudor facades
Multiple Winnetka properties appear on the National Register of Historic Places. Work on contributing structures may require custom lime mortar formulations, additional testing, and lead time that appears in the estimate’s timeline section. If an estimate for a 1930s Winnetka home has the same structure as one for a 1975 Northbrook ranch, one of them is wrong. For a full look at preservation-compliant work, see historic masonry restoration: preserving Chicagoland heritage.
Northbrook, 1960s to 1980s. Northbrook’s median home was built in 1968. The common brick type is hard machine-pressed brick, and the mortar recommendation is Type S for standard applications. These homes were built during the post-war building boom when production speed was prioritized and production-grade mortar was standard. After 40 to 60 years, that builder-grade mortar is reaching the end of its service life.
A Northbrook estimate in this era is structurally simpler:
- Standard Type S mortar, no custom blending required
- Removal to BIA TN-7B minimum (3/4 inch) throughout
- Access typically by ladder for single-story sections; scaffolding may be required for chimney work or full-facade tuckpointing on two-story homes
- Chimney line item if included, separate from wall tuckpointing
One Northbrook-specific item that should appear if relevant: garage wall crack repair. Northbrook’s split-levels and ranches commonly develop structural cracks in attached garage walls from foundation settlement. The estimate should distinguish between cosmetic mortar joint repointing and structural crack repair, which requires different technique and may need an engineer’s sign-off on the crack’s origin.
For a full cost framework relevant to both home types, see tuckpointing cost in Illinois 2026 and brick repair cost in Chicagoland 2026.
Joint Removal Depth: The Single Most Important Technical Item
BIA Technical Note 7B requires a minimum removal depth of 3/4 inch. This exists for a mechanical reason: mortar packed into a shallow groove cannot develop adequate bond surface area to hold against freeze-thaw cycling. The Chicagoland area experiences roughly 50 to 70 freeze-thaw cycles per winter. Each cycle exerts expansion pressure in the joint. Mortar held in by a 1/4-inch groove does not resist that pressure.
The practical consequence: shallow tuckpointing fails visibly within two to five seasons. Mortar pops out in rectangular plugs or crumbles at the edges. A new contractor removes the failed mortar and discovers the underlying joint was never removed to depth. The original mortar, still deteriorated, sits at the back of the joint. The problem was never addressed.
Your estimate should contain a sentence such as: “Mortar will be removed to a minimum depth of 3/4 inch per BIA Technical Note 7B using angle grinder with diamond blade and hand chisels. Dust and debris removed prior to mortar application.”
If it does not, ask the contractor to add it. If they say their method does not use that standard, ask why. A legitimate answer is that NPS Preservation Brief 2 governs the approach on historic soft-brick masonry, where hand chisels rather than angle grinders are used to avoid vibration damage. The 3/4-inch depth requirement does not change; only the removal method does.
Do not accept “we go deep enough” as an answer. Depth is a measurable specification. It belongs in the estimate. For a detailed walkthrough of what actually happens during a tuckpointing job, including how joint removal is staged and monitored, see what happens during a tuckpointing job.
Mortar Type: Why the Specification Must Be Explicit
Every masonry repair estimate should name the mortar type in ASTM C270 terms.
Type N has a minimum compressive strength of 750 PSI. It is appropriate for most above-grade residential brick work, pre-1970 homes with softer brick, and soft common brick from the historic Chicagoland inventory. It is the correct specification for most North Shore homes from the first half of the twentieth century.
Type S has a minimum compressive strength of 1,800 PSI. It is appropriate for below-grade work, retaining walls, foundation walls, and hard machine-pressed brick from the post-war building era. Northbrook, Deerfield, and Glenview homes from the 1960s through 1980s typically receive Type S. Type S is too hard for soft historic brick and will cause brick spalling if applied to pre-1920 masonry.
Type M has a minimum compressive strength of 2,500 PSI. It is appropriate for heavy structural applications and below-grade work under high lateral load. It is almost never appropriate for above-grade residential tuckpointing.
Lime-based or lime putty mortar is the correct specification for masonry built before 1920 and for any home where the original mortar analysis shows a high lime-to-Portland ratio. Evanston homes from the 1890s through 1920s, Kenilworth estate homes from the early 1900s, and any home where previous Portland cement repairs have caused spalling require lime-compatible mortar. Type O (minimum compressive strength of 350 PSI) is a standard lime-rich option for very soft historic brick.
An estimate that says “we match the existing mortar” without specifying the type is not an assurance. Matching the appearance is not the same as matching the compressive strength. For a full explanation of why this distinction matters structurally, see understanding tuckpointing: the complete guide.
Reading the Payment Schedule and Warranty
Payment schedule. Standard residential masonry in the Chicagoland market runs on a deposit-at-signing, balance-on-completion structure. Reputable contractors typically request 25 to 35 percent at signing to cover materials procurement. Amounts above 50 percent remove the contractor’s financial incentive to complete work to specification. Full payment before work begins is a significant risk.
For larger projects, a three-stage schedule is standard: deposit at contract signing, payment after substantial completion, and final payment after walkthrough. Each stage should be defined by a completion milestone, not by a calendar date.
Warranty. The warranty should state clearly:
- Duration: one to five years is typical for tuckpointing warranties in this market
- Scope: labor and materials, or labor only
- Exclusions: seasonal movement, freeze-thaw, and normal weathering are standard exclusions; these are not defects in the installation
- What is not an acceptable exclusion: installation errors, mortar failure from incorrect type specification, joint adhesion failure from inadequate removal depth
A warranty that is only verbal is not a warranty. Courts do not enforce verbal warranties for construction work. If the contractor will not put the warranty terms in writing, do not sign the contract.

The Deerfield Case: Lintel Replacement Line Items
Deerfield homes from the 1960s through 1980s have a documented problem that requires specific attention in any masonry estimate: steel lintel rust above windows and doors. Deerfield’s median home was built in 1970. Steel lintels above window and door openings on these homes are corroding after decades of moisture exposure. Rusting steel expands, pushing the brick above it outward and cracking the surrounding mortar.
An estimate for a Deerfield home showing horizontal cracks above window openings, rust staining on the brick face below a window, or a slight outward bulge in brick courses above an opening must include a separate line item for lintel assessment and potential replacement. The scope for this work differs from tuckpointing:
- Lintel replacement with brick reset: $2,000 to $5,000 per opening depending on size and access
- This scope requires removing the brick above the lintel, extracting and replacing the corroded steel, resetting the displaced brick, and repointing the entire section
- Simply repointing the mortar around displaced brick does not address the expanding steel causing the displacement
If you have a Deerfield home and the estimate does not address lintels while your walls show the above symptoms, ask the contractor directly whether lintel condition was checked during the site visit. For more on how to identify crack patterns that indicate structural causes versus surface deterioration, see how to read cracks in a brick wall.
How to Compare Two Bids Accurately
You have two estimates in front of you. One is $2,400. The other is $3,100. Before assuming the lower bid is the better deal, check each of the following on both documents.
Is the scope identical? Compare the elevations listed. If one estimate covers the front facade and chimney and the other covers front, north, and chimney, they are not the same scope.
Is the mortar type the same? If one specifies Type N and the other specifies Type S on the same historic brick, only one of them is correct. If the cheaper estimate specifies the wrong mortar type, it is not cheaper. It is a project that will damage your brick.
Is the removal depth the same? If one specifies 3/4 inch per BIA TN-7B and the other specifies “full removal of deteriorated mortar” without a depth measurement, they are not comparable. Ask the second contractor what depth that phrase represents in practice.
Is the access method the same? If one contractor prices scaffolding and the other prices ladder access for the same tall facade, the quality outcomes will differ. Precise joint work at height requires stable staging.
What does each warranty cover? A one-year warranty and a three-year warranty on identical scopes produce different long-term risk to you as the homeowner.
Once these variables are equalized, price differences reflect overhead structure, crew composition, and company reputation. A premium for a contractor who has been doing this work across Chicagoland since 1987 and provides a documented warranty is a different calculation than the same premium from a contractor you cannot verify.

Red Flags in a Masonry Repair Estimate
Six specific problems in an estimate should make you pause before signing.
No itemized scope. A single line item such as “tuckpointing per your home” without elevations, footage, or mortar specification is not a contract. It is a number with no basis for dispute.
No mortar type named. Mortar type is the most technically consequential item on the estimate. A contractor who will not name the type either does not know what they will use or does not want to be held to a specification.
No joint removal depth. BIA Technical Note 7B is the industry standard. A contractor who will not cite it is either unaware of it or plans to skip compliance.
Full payment requested before work begins. This is outside market norms and removes the homeowner’s primary financial leverage.
Bid substantially below others without explanation. A 40 percent lower bid is more often a signal of shallower joint removal, cheaper mortar, or ladder-only access where scaffolding is needed.
No written warranty. Verbal promises are not enforceable. If it is not on paper, it does not exist.
What a Final Review of the Estimate Should Confirm
Before signing any masonry repair estimate, run through this list. Every item should have a clear answer from the written document.
Do I know which walls or sections are being worked on? If not, ask for itemization by elevation.
Do I know the mortar type for each section? If not, ask in writing.
Does the estimate reference 3/4-inch minimum removal depth? If not, ask the contractor to confirm the depth in writing.
If brick replacement is included, do I know approximately how many bricks and how they will be sourced? If not, ask.
Do I know how the contractor will access upper floors or the chimney? If not, ask.
Do I know the payment schedule and what each payment is tied to? If not, ask for a milestone-based schedule.
Do I have a written warranty with defined terms, duration, and exclusions? If not, require one before signing.
