Signs to watch
Is this you?
You want the familiar, budget-friendly window
These three are the everyday styles for good reason — simple operation and the lowest cost of the operable windows we install. The trick is matching the style to how each room actually gets used.
A window that's hard to reach to open
Over a counter or behind a sofa, a side-sliding window you push sideways is often easier to work than a hung window you lift — a real consideration for kitchens and low, wide openings.
Cleaning the outside from inside
If you've got second-story windows you dread cleaning, a double-hung whose sashes tilt in solves exactly that. Single-hungs and sliders are harder to clean from inside up high.
Drafts around an old hung or sliding window
These styles seal along tracks that must stay loose enough to move, so worn weatherstripping shows up as drafts. Modern units with good seals close that gap — though they'll never seal quite as tight as a crank-out casement.
Your options
The three styles, compared straight
A single-hung window has two sashes stacked vertically, but only the bottom one moves up; the top is fixed. A double-hung looks the same but both sashes move, and better ones tilt inward for cleaning — which is the big practical advantage upstairs. A slider (or sliding window) has sashes that glide side to side on a track, which suits wide openings and spots where reaching up to lift a sash is awkward, like over a kitchen sink. On ventilation: a slider opens up to half its width; a single-hung vents from the bottom only; a double-hung can open top and bottom together to let warm air out the top and cooler air in the bottom. On cost, single-hung is typically the least expensive because it has one less moving sash, slider is close behind, and double-hung costs a bit more for that second operating sash and the tilt feature. On sealing, all three seal along tracks and are very good with modern weatherstripping, but none seal quite as tight as a crank-out casement — a fair trade for their simplicity and price. We'll match the style to each room rather than default the whole house to one.
The method
How we do it
- 01
Match style to each room
We look at reach, cleaning access, ventilation needs, and egress for each opening, then recommend slider, single-hung, or double-hung by room — not one style for the whole house.
- 02
Install square, sealed, and flashed
Old units out, openings checked for rot, new units set square, insulated, flashed, and sealed — tracks aligned true so the sashes glide and seal as designed.

Function walkthrough
Every window opened, locked, and — on double-hungs — tilted in with you watching, so you know how to clean and operate them before we sign off.
Straight numbers
Cost, by style
These three are the value styles among operable windows. Single-hung is usually the least expensive because only one sash moves; sliders sit close behind; double-hung costs a bit more for the second operating sash and tilt-in cleaning. All three come in below crank-out casements. The right choice per room is rarely about squeezing the last dollar — it's putting the tilt-in double-hung where you'll clean it and the easy-reach slider where you'll open it daily. Frame material, size, and glass package move the number, and whole-home projects get volume pricing in writing.
Where we do this work
Sliding, Single-Hung & Double-Hung Windows: straight answers
What's the difference between single-hung and double-hung?
On a single-hung, only the bottom sash moves and the top is fixed. On a double-hung, both sashes move, and most tilt inward so you can clean the outside glass from inside — a real advantage on upper floors. Double-hung costs a bit more for that second operating sash and the tilt feature; single-hung is the value pick where cleaning access isn't an issue.
Which ventilates better, a slider or a hung window?
A slider opens up to about half its width and suits wide openings. A double-hung can open at the top and bottom at once, which vents warm air out the top while drawing cooler air in the bottom — the best natural airflow of the three. A single-hung vents from the bottom only. We match the style to how you'll actually use the room's air.
Do these seal as well as a casement?
Honestly, no — sliders and hung windows seal along tracks that have to stay loose enough to move, while a casement cranks tight against the frame. With modern weatherstripping these three seal very well and are more than adequate for most homes; if a specific opening demands the tightest possible seal against wind and rain, that's where we'd point you to a casement instead.
Which style is easiest to clean upstairs?
A double-hung, clearly — both sashes tilt inward so you clean the exterior glass from inside the room, no ladder. Single-hungs and sliders are harder to clean from inside on upper floors. If dread of cleaning second-story windows is driving your choice, double-hung is the answer worth its small premium.
