Wilmette Masonry Is Not One Building Type
Wilmette was incorporated in 1872 and extends west from Lake Michigan through several established neighborhoods and commercial districts. The Village describes its character through its single-family residences, commercial areas, brick-paved streets, tree-lined streets and proximity to the lake.
That variety means a masonry repair should be planned for the individual property—not for a generalized Wilmette construction era.
Before defining the work, we may consider:
- Existing brick, stone or concrete masonry
- Original and later mortar repairs
- Wall and chimney construction
- Cracking, movement or corrosion
- Decorative masonry details
- Drainage around the affected area
- Prior patches or coatings
- Access and staging
- Permit or property-review requirements
- Availability of compatible replacement materials
The goal is to repair what has failed while preserving materials that remain serviceable.
Four Property Contexts That Can Change the Repair Plan
1. A single-family residence
Work on a house may involve tuckpointing, selective brick replacement, chimney repair, entrance masonry or exterior concrete.
Even within one neighborhood, walls may differ in brick, mortar, exposure and previous repairs. Construction year alone cannot determine the appropriate mortar or repair method.
2. A locally designated landmark
Wilmette currently has 38 local landmarks protected through its Historic Preservation Ordinance. The Historic Preservation Commission reviews proposals to alter or demolish local landmarks.
Visible masonry changes on a local landmark may require attention to:
- Existing brick or stone dimensions
- Mortar appearance
- Joint profiles
- Decorative masonry
- Replacement-material samples
- Earlier restoration work
- Proposed changes to the exterior
The property’s designation and proposed scope should be confirmed before materials are ordered.
3. A property in a National Register district
Wilmette has three National Register historic districts: Village Center, Oak Circle and Ouilmette North. The Village also lists nine individual National Register properties.
National Register listing is primarily honorific and does not provide the same local protection as Wilmette landmark designation. A property may therefore be historically significant without every repair following the local-landmark review process.
4. A commercial or multifamily property
Wilmette’s Appearance Review Commission reviews the appearance of commercial and multifamily buildings as well as commercial signage. It does not review every exterior repair on every single-family home.
Commercial or multifamily masonry planning may also need to address:
- Work around occupied entrances
- Property-management coordination
- Scaffolding or lift access
- Pedestrian routes
- Material samples
- Phased work
- Appearance Review
- Permit and inspection responsibilities

Is the Mortar Failing, or Is the Brick Damaged?
This distinction determines whether tuckpointing alone is likely to be appropriate.
Deteriorated mortar
Tuckpointing may be considered when mortar is cracked, loose, recessed or missing while the surrounding brick remains serviceable.
Before replacement mortar is selected, the existing brick, previous mortar, wall construction and joint appearance should be evaluated.
Damaged brick
Brick repair may be required when individual masonry units are cracked, loose or losing portions of their surface.
Depending on the condition, the work may include:
- Replacing selected bricks
- Resetting loose masonry
- Repairing adjacent joints
- Rebuilding a limited section
- Removing a failed patch
- Correcting damage around an opening
Replacement brick should be evaluated for size, color, texture and compatibility with the surrounding wall.
Mortar Compatibility Cannot Be Determined by Age Alone
An older Wilmette property does not automatically require one predefined mortar type.
Before selecting replacement mortar, the repair should consider:
- Brick condition and hardness
- Existing and previous mortar
- Wall construction
- Joint width, depth and profile
- Moisture exposure
- Earlier repointing
- Required appearance
- The purpose of the repair
Terms such as “historic mortar,” “lime mortar” and “Type N” should not be treated as interchangeable specifications.
The replacement material should be selected for the actual wall—not simply because the building was constructed before a particular year.
Cracking Around Windows and Doors
Cracking above or beside a window, door or garage opening may involve more than deteriorated mortar.
Possible conditions include:
- Failed joints
- Damaged brick
- Moisture entry
- Corrosion of embedded steel
- Movement around the opening
- Separation between different materials
A surface patch may conceal the crack temporarily without correcting the cause.
The estimate should explain whether the proposed work includes mortar repair, brick removal, steel-related work or selective rebuilding. Not every crack requires lintel replacement, and tuckpointing alone is not appropriate for every opening.

Chimney Repair in Wilmette
Because a chimney extends above the roofline, its brick, mortar, crown and flashing area receive direct weather exposure.
An exterior inspection may identify:
- Open mortar joints
- Cracked or spalling brick
- Loose upper courses
- Crown deterioration
- Moisture near the flashing
- Earlier patches separating
- Leaning or visible displacement
The written scope should explain whether the repair is limited to the crown or upper masonry, or whether a larger portion of the exterior chimney requires work.
Permit requirements depend on the proposed repair. Wilmette states that its residential permit list is not all-inclusive and advises property owners and contractors to contact Community Development when the requirement is unclear.

Stone, Limestone and Masonry Details
Wilmette properties may include natural stone, limestone, cast-stone elements or masonry veneer around entrances, windows, columns and exterior walls.
Repair may involve:
- Repointing stone joints
- Resetting loose units
- Replacing selected pieces
- Repairing supporting masonry
- Addressing movement between materials
- Reviewing flashing and drainage
- Cleaning with a surface-appropriate method
Loose stone or veneer may indicate a problem behind the visible surface. The supporting masonry, attachment and moisture-management details should be considered before a cosmetic repair is proposed.

Village Center and Other Commercial Properties
Village Center is Wilmette’s central business district and is intended to retain the community’s historic, small-town character while supporting retail, dining, housing and transportation needs. Wilmette also has several other established commercial districts.
Masonry work on a storefront, mixed-use building or multifamily property may involve:
- Facade tuckpointing
- Brick replacement
- Lintel-related work
- Limestone or stone repair
- Parapet masonry
- Work around public entrances
- Access and pedestrian protection
- Coordination with owners or tenants
Appearance Review and permit requirements should be confirmed according to the property and proposed exterior changes.
Concrete, Patios and Site Drainage
Wilmette requires residential permits for patios, sidewalks, grading, drain tile and basement-waterproofing work. The Village notes that its permit list is not exhaustive.
Concrete repair or replacement should be based on visible condition and stability rather than age alone.
Reasons to request an evaluation may include:
- Settlement
- Widespread cracking
- Uneven walking surfaces
- Surface deterioration
- Separation from adjoining materials
- Water collecting near the building
- Repeated patch failure
Wilmette also requires stormwater management when a project creates a net increase in impervious surface coverage. Site conditions—including available space, soil and seasonal water-table height—can affect the required stormwater approach.
A proposal involving a new or enlarged patio, walkway or other impervious surface should identify whether grading, drainage plans or stormwater measures are included.
Moisture Signs Should Be Traced to Their Source
White mineral deposits, dark staining, lower-wall deterioration and repeated patch failure can be associated with moisture moving through or around masonry.
The visible symptom does not identify the source by itself.
An inspection may need to consider:
- Roof and downspout discharge
- Grading
- Patios and other impervious surfaces
- Open masonry joints
- Cracks near grade
- Previous waterproofing
- Drainage around entrances
- Seasonal site conditions
Wilmette notes that intense rain can exceed soil absorption and contribute to yard flooding or basement seepage, especially where runoff from roofs, patios and driveways adds to the water load.
The masonry repair and any separate drainage work should be clearly distinguished in the estimate.
Historic Preservation and Appearance Review Are Different
Wilmette’s Historic Preservation Commission and Appearance Review Commission have different responsibilities.
The Historic Preservation Commission identifies landmarks, recommends official designation and reviews proposals to alter or demolish local landmarks.
The Appearance Review Commission reviews commercial and multifamily buildings and commercial signage.
Not every private home or exterior masonry repair follows either process.
The property status and proposed changes should be confirmed before assuming which Village review applies.

Wilmette Permit Planning
Wilmette requires permits for many construction, remodeling and property-improvement projects. Its published residential list includes patios, sidewalks, grading, waterproofing and other work, but the Village notes that the list is not all-inclusive.
Permit requirements for tuckpointing, brick repair, chimney work, concrete and drainage-related improvements depend on the proposed scope.
Property owners and contractors should confirm current requirements with the Community Development Department before work begins.
The written estimate should state whether permit fees, drawings, engineering, Village review and inspections are included.
