Window Replacement Standards

(San Francisco)


The San Francisco Planning Department implemented the Residential Design Guide in 2003.   The document states that replacement windows in San Francisco, facing the street/ public walk-way, must be “in kind.”  That is, the original wood windows should be replaced with like-for-like wood sash window replicas, to keep in tune with the architectural integrity of building's time period of when it was built.


“If replacement windows are required due to deterioration, those that are visible from the street or other public rights-of-way should be replaced with windows that are appropriate to the time period your building was originally constructed.  Replacement windows should match the HISTORIC windows in size, glazing, operation, material, finish, exterior profiles and arrangement.”

The Anatomy of a Window

Wooden Sash Windows are Elegant and Versatile

Wooden sash windows  are very much part of the history of houses, because they maintain the architectural integrity and value of home.  It is actually rather hard to imagine homes of various styles throughout the years without sash windows.

Sash windows became popular in the 1800s and 1900s as status symbol.  This style of window was very popular until the 1950s, when homeowners began removing this style of window in an attempt to modernize their homes.  This continued through the end of the century, when finally some folks, concerned with the historical appearance of their homes, began to reinstate and again use the sash windows.



The Advantages of Wooden Sash Windows

Aside from the historical and traditional beauty, and the style of installing or owning wooden sash windows, there are some other distinct advantages that this type of window offers outside of its appearance.  That is, they can be planed and retrofitted over the years for proper functionality if necessary.  For example, if your foundation gives over the years, the sides of sash can be shaved to fit and work as they once did.  Because our well crafted windows will acclimate over time in response to level of humidity that they are exposed to, they can expand and contract within frame without  losing its true geometrical plane.  In addition, proper weatherstripping and/or sealant will maximize the U-value of any fenestration.  With proper care wooden windows can be made to last a lifetime for years of enjoyment.  


The Style

The style and tradition of wooden sash windows has been lost in so many homes today.  If you walk down a Victorian or Edwardian street, you are very likely to see many modern windows, this of course completely detracts from the overall appearance of the period home.  These  wooden sash windows are not only gorgeous to look at but excellent for insulating.  Their beauty and functionality make them great for homes.  Being both versatile and economically friendly, these windows are great for any home.



Practical and Economical

Wooden sash windows are also beneficial since wood is a good insulator, protecting the interior of the home from the elements and keeping the temperatures consistent.  Wooden window products are also designed in a number of shapes and sizes to meet just about any need you may have for your home, whether more standard or very unique.  Another really important factor to consider is that wood windows are environmentally friendly.  Other non-natural materials and aluminum can’t say the same thing. In today’s increasingly eco-friendly world, many people are opting for natural products where it meets their needs.

FSC Certified Timber

(Douglas Fir)


Most  of our products are made of FSC Certified Douglas Fir Wood, which is the Pacific North West dominant tree, and more importantly an environmentally responsible specie of wood to use for any project.  However, we will use any available wood specie per customer's request.  

"The logging practices of the last 200 years created artificial disturbances that caused Douglas-firs to thrive.  The Douglas-fir's useful wood and its quick growth make it the crop of choice for many timber companies, which typically replant a clear-cut area with Douglas-fir saplings.  The low-moisture conditions that exist within a clear-cut also naturally favor the regeneration of Douglas-fir.  Because of clear-cut logging, almost all the Pacific Northwest forests not strictly set aside for protection are today dominated by Douglas-fir, while the normally dominant climax species, such as Western Hemlock and Western Redcedar are relatively rare."
