Window Sills
Cast stone sill profiles for windows, openings, veneer transitions, and coordinated façade surrounds.

Lines that define architecture
Precisely cast window surrounds, sills, bands, cornices, crowns, and custom profiles.
Architectural
Precast mouldings and window sills give openings, rooflines, and façades durable definition. Controlled casting produces repeatable shapes and detailed profiles before components arrive on site.
Landmark Stone fabricates decorative and functional elements for traditional, transitional, and contemporary architecture, with custom sizes, textures, and finishes coordinated to the project.
Why it works
Applications
A starting point for design conversations. Project conditions, engineering, attachment, and local requirements should be reviewed for the final assembly.
Interactive catalogue
Choose a family, search model references, study the form from multiple angles, test digital finishes, and hold up to three options for comparison. Final geometry and dimensions remain tied to the official catalogue and project review.
14 catalogue references · 1 family · four digital finish studies
Real-time 3D geometry for design review—not a dimensional shop drawing. Procedural forms, screen color, and texture are approximate; confirm final geometry and finish with catalogue details, drawings, and a physical sample.
Selected reference
Select two or three references above to compare them in 3D.

13 project images
This product-focused library brings together installed work, close details, scale, junctions, and finish character. Select any image to study it at a larger size.
From reference to release
A catalogue code is a useful starting point, not the whole specification. Send the available project information and the team can help close the gaps before fabrication.
Start a Mouldings & Sills reviewPlans, elevations, sections, field measurements, or a marked-up sketch.
A catalogue model, inspiration image, or profile that establishes the desired character.
Piece counts, linear footage, corners, radii, returns, openings, and repeated conditions.
Target color, texture, adjacent materials, and the light conditions used for sample approval.
Substrate, attachment assumptions, delivery sequence, site access, and required milestone dates.
Common planning questions
Yes. Catalogue families establish proportion and design direction. Final size, length, returns, radius conditions, color, texture, and project interfaces can be reviewed for the selected application.
Send the model or design reference, dimensioned drawings when available, quantities, project location, desired finish, and schedule. Early sketches are also welcome when details are still being developed.
Digital finish studies help narrow the direction, but physical samples should be reviewed beside adjacent materials and in the project’s actual light before final approval.
The final assembly depends on piece geometry, substrate, loading, access, and local requirements. These conditions should be coordinated with the project team before release.
Technical review
Use these values for early material evaluation. Confirm final dimensions, tolerances, engineering, finish samples, and installation requirements with the Landmark Stone team.
