Made-to-match wood windows, doors, sash, and mouldings for Los Angeles historic properties
Original wood windows and doors give an older home its proportions, character, and architectural identity. When an original unit is beyond repair—or when a missing component must be recreated—a stock replacement is rarely a suitable answer.
Custom Mouldings, Sash & Doors manufactures made-to-order wood windows, doors, replacement sash, and mouldings from our Van Nuys shop. Bring us an existing sample, drawings, dimensions, or clear photographs. We can build a new unit to match the details that make your property distinctive.
Historic details we can reproduce
Every property is different. We build custom wood products around the existing opening, architectural style, and details of the original work.

A practical approach to historic matching
Our work begins with the original details. A close-up photo or physical sample can reveal the profile, proportions, joinery, glazing arrangement, and trim details needed to recreate the piece accurately.
- Send photographs, dimensions, drawings, or a sample. Include full views plus close-ups of the sash, muntins, casing, sill, or door profile.
- We review the existing details and project requirements. This includes operation, opening size, wood species, glass, finish, and any special conditions.
- CMSD prepares the custom product for your approval. For detailed work, this may include a shop drawing or profile confirmation before production.
- Your unit is manufactured to order in Van Nuys. We produce the custom woodwork for the actual job—not a closest-available stock substitute.
Built for historic character and current project needs
Historic projects often require careful coordination between the original appearance, present-day building requirements, and the practical needs of the home. We work with homeowners, architects, contractors, and designers to manufacture the custom wood components specified for the project.
CMSD can match key visual features such as window proportions, sash layout, muntin patterns, profiles, rail and stile dimensions, door panel layout, casing, and moulding details. For appropriate projects, we can manufacture units for insulated glass and prepare prehung door assemblies to the required specifications.
For properties subject to historic-district or landmark review, we provide the custom manufactured product and project information needed by your team. Final design review, permitting, and approval remain with the property owner and the applicable jurisdiction.
Historic properties and special projects throughout greater Los Angeles
We serve customers throughout the San Fernando Valley and greater Los Angeles, including historic homes and renovation projects in Van Nuys, Sherman Oaks, Studio City, Encino, Pasadena, Larchmont, Hancock Park, Beverly Hills, Los Angeles, and surrounding communities.
Whether the project is a single replacement sash, an original entry door, a matched casing profile, or a complete set of custom wood windows, CMSD builds to the dimensions and details of your property.
Recent made-to-match work
Larchmont wood sash replacement
CMSD replicated original wood sash profiles for a Larchmont residence near Hancock Park and manufactured replacement sash to match the existing frames. The project incorporated new insulated glass units while retaining the appearance and character of the original wood windows.
These completed exterior views show the matched double-hung and bay-window work on the residence.
