Choosing Between Custom Windows Vs. Standard Replacement Window Sizes

After earning their Harvard MBAs, two women had a vision to create a service that would allow shoppers to rent designer clothing and accessories, and ultimately founded an app called Rent the Runway.  In less than 15 years, Rent the Runway is now valued at over $800 million.  A primary reason for this is that each outfit comes with a backup size.  This stops the renter’s regret, as manufacturers differ on which dimensions correspond with a size.

In many industries, standard manufacturing sizes are not always the universal norm.  This is particularly true in the home improvement sector for window replacement.  Here’s what you need to know about custom windows vs. standard windows.

Differences Between Custom & Stock Windows

When comparing stock vs. custom windows, the major thing you need to know is that standard windows are created in most sizes that are common across the majority of homes, and they are mass produced.  Custom-built window sizes, on the other hand, are made for the specific space they are installed.

One prevalent myth is that stock windows will fit into a stock-sized opening.  Depending on your home, this may or may not be true.  There are significant fluctuations in the way walls are built.  Some contractors follow house plans to a tee, while others use them as a general guideline and adjust during new construction builds to make residential windows fit as they should.

Additionally, as a house progresses in age, its foundation can shift slightly.  This, in turn, can alter a window’s opening so that a stock size is no longer a perfect fit. Custom-built windows can cost more upfront, but they often perform better.

Methods Of Installing Standard Window Replacements

Because house windows are typically not replaced very often, it’s important to note that current installation techniques are likely different from when the home was initially built.

For example, during new construction, residential windows are put in before siding is installed.  But when you need new windows after your home is built, it may require some siding to be torn off if they are not custom fit.  Depending on the existing type of siding installation you have, it can be difficult to match with the siding repair.  This is because the original siding has been weathered by Mother Nature and is oftentimes not the same hue it was when it was installed.

During stock window installation, it’s common to end up damaging the immediate interior wall surrounding the window as a result of adjustments made for it to fit.  Alternatively, homeowners that choose have replacement windows made for each rough opening will likely experience fewer headaches as a result.

Standard Replacement Windows Can Save Time & Money

Stock windows aren’t all bad.  They can be acquired much quicker than custom made windows, if you’re in a situation where time is of the essence, they can be the way to go.  Just bear in mind that the installation costs associated with stock windows may be higher than custom made windows, since modifications are likely needed for the stock window to accommodate openings properly.


How Window Inserts & Full Frame Installation Vary

How much new windows cost often depends on the installation technique used.  While full frame window installation costs more upfront, it often is the best option.  Unlike inserts, full frame windows allow for the inspection of the rough opening. This ensures that air and water infiltration, along with dry rot can be corrected.

Window inserts only allow for the replacement of the sash.  This replacement window often lowers the amount of natural light in a home. This is particularly unappealing when replacement specialty windows are being installed.
