Window Treatments for Older Seattle Homes: How to Handle Non Standard Windows Without the Headache

If you live in an older Seattle home, you probably love the charm. The trim has character. The windows feel tall and classic. The whole place has that lived in warmth you just cannot fake.
But when it comes to window treatments, that charm can turn into a very specific kind of frustration.
You measure the window. You buy something you think will fit. You install it. Then you step back and realize something is off. There is a gap on one side. The top sits slightly crooked. The shade rubs on the trim. Or the blinds look straight until you notice the window itself is not perfectly square.
If you have ever felt personally attacked by a Seattle Craftsman window, welcome. You are in the right place.
This guide walks through the real reasons older windows are tricky, what types of window treatments work best, and how to avoid the most common mistakes. It is written for actual Seattle homes, not perfect showroom windows.
If you want help measuring and choosing a custom option that fits cleanly, Ultimate Shutters and Blinds can help. You can start here.
Why Older Seattle Windows Are So Often Non Standard
Most older Seattle homes were built long before everything was mass produced to standard sizes. Add decades of settling, paint layers, and small renovations, and you end up with windows that are slightly different from what you expect.
Common things we see in older homes.
Window openings that are not perfectly square
Trim that is thicker on one side than the other
Frames that have shifted slightly over time
Multiple paint layers that affect how tight an inside mount can fit
Beautiful woodwork that you do not want to cover up
None of this means your windows are bad. It just means the solution needs to fit the house, not fight it.
The Number One Decision: Inside Mount vs Outside Mount
This is where most people get stuck. It sounds like a small detail, but it changes everything, especially in older homes.
Inside mount
Inside mount sits inside the window frame. It looks clean and built in, and it is a popular choice when you have deep enough frames.
But in older homes, inside mount can be tricky because the frame is not always perfectly even. If the opening is slightly off, the treatment can sit crooked or rub.
Inside mount works best when
The window frame is deep enough
The opening is reasonably even
You want a clean tailored look
You are okay with small light gaps around edges
Outside mount
Outside mount sits on or above the trim and extends past the window opening.
In older Seattle homes, outside mount is often the easiest way to solve fit problems. It can help cover uneven edges, reduce light gaps, and avoid rubbing on old trim.
Outside mount works best when
The window opening is not even
You want to reduce light gaps
You need more coverage for privacy
You want to avoid tight fitting issues
A lot of people assume inside mount is always the better option because it looks cleaner. In older homes, outside mount can actually look better because it sits straight even when the window is slightly off.
Best Window Treatment Types for Older Seattle Homes
Now let’s talk about what actually works.
Cellular shades for comfort and weird windows
Cellular shades are one of the most forgiving options for older homes. They work well in slightly uneven openings, they help reduce drafts, and they give you great light control options.
They also look clean without covering your trim in a bulky way, which matters in Craftsman style homes.
Best for
Drafty rooms
Bedrooms where comfort matters
Older windows that are not perfectly square
Homeowners who want a simple finished look
Roller shades for a modern look without fighting the trim
Older homes can absolutely handle modern design, especially when you choose something clean like roller shades.
Roller shades are also a great option when you do not want slats, cords, or a busy look.
If you choose the right fabric, you can keep the room feeling bright while controlling glare or privacy.
Best for
Living rooms and dining rooms
Home offices
Homes that want a cleaner look
Windows where you want the trim to stay the star
Wood and faux wood blinds for classic style
Blinds can look great in older homes, especially when you want something traditional that matches wood trim.
Faux wood is often chosen in kitchens and bathrooms because it handles moisture better.
The biggest thing with blinds in older homes is fit. Slightly uneven windows can create small gaps or make the blind sit a little off if it is not measured and installed carefully.
Best for
Homes with wood trim
Guest rooms
Spaces where adjustable light control matters

Plantation shutters for a built in upgrade
Shutters are popular in older Seattle homes because they look like they belong. They feel permanent, they add value, and they handle privacy and light control well.
Shutters can also be a great solution when you have slightly uneven openings because they are custom built to fit.
Best for
Street facing windows
Homes with close neighbors
Homeowners who want a timeless built in look
Rooms where privacy is a big deal

How to Avoid the Most Common Older Home Window Treatment Mistakes
You can save yourself so much frustration by knowing what usually goes wrong.
Measuring once and assuming all windows match
In older homes, two windows that look identical often are not. Always measure each window separately. Even if they are side by side.
Ignoring the trim and hardware details
Older homes have beautiful trim and sometimes older window hardware. The treatment needs to clear those details.
If a shade rubs on trim or hits a latch, you will hate it every day.
Choosing style before solving the real problem
A lot of people start with, I want this look. But the smarter first question is, what problem am I solving.
Is it glare
Is it privacy
Is it drafts
Is it sleep
Is it making the room look finished
Once you know that, the style becomes easier.
Buying off the shelf and hoping it works
It can work sometimes. But in older Seattle homes, off the shelf options often lead to gaps, uneven fits, and that slightly awkward look that makes the room feel unfinished.
Custom is not about being fancy. It is about fit.
Seattle Older Homes and Drafty Windows
Seattle homes often deal with drafts, especially in bedrooms and living rooms with older window frames.
Window treatments cannot replace insulation, but they can help reduce that cold feeling near windows.
Cellular shades are popular here because they create an insulating layer of air. Shutters can also help because they add a solid barrier at the window.

What to Do If You Want Privacy Without Losing the Look of Your Home
Older homes often have windows that face sidewalks or neighbors. You want privacy, but you do not want to cover up the charm.
Here are a few approaches that work well.
Shutters for adjustable privacy
Top down bottom up shades for flexible coverage
Layered treatments where a shade handles privacy and a curtain adds softness
The goal is to keep the room feeling bright and welcoming while still giving you privacy when you need it.
Why Custom Makes a Bigger Difference in Older Seattle Homes
This is the simple truth. Older homes do not play nice with one size fits all solutions.
Custom window treatments are measured to your window opening and trim. That is why they sit straighter, look cleaner, and work better.
They also help protect the look of the home because you are not forcing a modern standard size product onto a unique older frame.

Final Thoughts: You Can Keep the Charm and Still Make Life Easier
Older Seattle homes are worth the effort. They have style, warmth, and personality.
The right window treatments should support that, not fight it.
If your current coverings are gapping, rubbing, or just not sitting straight, it is not you. It is the window. And it is fixable.
