Delta – Masonry and Tuckpointing provides natural-stone masonry repair and restoration for residential and commercial properties across Chicagoland.
We repair stone walls, veneers, steps, columns, pillars and exterior architectural features. Before recommending work, we evaluate the visible damage, existing mortar, stone condition and wall construction.
Stone walls may develop loose units, failed mortar joints, cracking, movement or moisture-related deterioration.
Depending on the condition, repairs may include:
The repair scope depends on whether deterioration is limited to the joints or affects the surrounding stone and supporting masonry.
Loose, bulging or separating stone veneer may indicate a problem with the mortar, supporting surface, attachment materials or moisture behind the stone.
Stone veneer repair may involve removing unstable sections, repairing the supporting area and resetting or replacing the affected stone.
A surface mortar patch may not correct a problem that begins behind the visible veneer.
Exterior stone steps are exposed to moisture, freezing temperatures, foot traffic and de-icing materials.
Stone-step work may include:
The supporting base, surrounding masonry and drainage should also be considered during the inspection.
Stone columns and pillars may need repair when joints open, individual stones loosen or sections begin to shift.
The proposed work depends on whether the deterioration is limited to exterior mortar or extends into the supporting masonry.
Stone repointing removes deteriorated mortar and replaces it with mortar selected for the existing stone and wall construction.
The replacement mortar should be compatible with the surrounding masonry in strength, appearance and moisture performance.
The National Park Service guidance on repointing historic masonry provides additional information about evaluating existing mortar and selecting compatible repair materials.
Consider scheduling an inspection when you notice:
Stone damage may be limited to one area, or it may be related to moisture, movement, drainage or deterioration behind the visible surface.
Not every damaged stone feature requires complete rebuilding.
The written estimate should identify whether the proposed work includes repointing, resetting, replacement or partial rebuilding.
We inspect the stone, mortar joints, wall construction and visible areas of deterioration.
We determine which areas may require repointing, resetting, replacement or rebuilding.
The existing stone and mortar are considered when replacement materials are selected.
Loose material and failed mortar are removed from the identified repair area.
The approved repairs are completed according to the written scope.
The completed area is reviewed, and applicable care or warranty information is provided.
Delta is headquartered in Libertyville and provides stone masonry repair throughout Lake County, Chicago’s North Shore, the northwest suburbs and northern Cook County.
Property conditions vary by building type, stone material, exposure and construction. These conditions are evaluated before the repair scope is prepared.
View All Service AreasStone damage may be related to other areas of the masonry assembly. Related services include:
Some loose stones can be removed and reset when the material remains suitable for reuse.
The surrounding mortar and supporting wall should also be evaluated.
Not necessarily.
When the stone remains stable and serviceable, repointing the surrounding joints may be sufficient.
It may be repairable depending on the cause and extent of the failure.
The supporting surface and attachment method may need repair before the stone is reset.
Matching may consider the stone type, color, texture, dimensions and surface finish.
An exact match may not always be available, particularly for older or weathered stone.
Not every stone surface needs a water-repellent treatment.
The stone, mortar, moisture source and wall construction should be evaluated first.
Qualifying projects include written workmanship warranty terms.
The signed estimate and completion documents identify the applicable coverage, duration and exclusions.
Review the Workmanship WarrantyLoose stone, deteriorated mortar and movement do not always require the same repair.
Delta evaluates the affected area and prepares a written estimate describing the proposed work.
