Single & Double Hung Windows Toronto
Keep the familiar look of vertically sliding windows while planning a practical replacement. Compare single and double hung operation, cleaning access and glass options for your GTA home.
How hung windows work
A hung window opens vertically. In a single hung design, the lower sash moves and the upper sash remains fixed. In a double hung design, both sashes can move. Tilt-in cleaning is a separate product feature to confirm, rather than something to assume from the name.
Keep a traditional window rhythm
The horizontal meeting rail and tall proportions can suit many established neighbourhoods. Match the grille layout, frame width and exterior trim to the home.
Choose how the sashes open
Double hung operation allows openings at the top or bottom. Actual airflow depends on the room and weather. Screens are for insects and do not provide fall protection.
Plan cleaning access
Tilt-in sashes can make some cleaning tasks easier when used according to the manufacturer’s instructions. Ask which sashes tilt and how they must be supported.
Choose the right fit for your room
Hung windows can suit bedrooms, living rooms, kitchens and home offices, especially where exterior swing clearance is limited. Make sure the sash can be lifted comfortably from its installed position. Heritage properties and condominium buildings may have approval requirements for appearance or replacement work.
Single hung vs. double hung windows
| Configuration | How it works | What to check |
|---|---|---|
| Moving sashes | Single hung: lower sash only | Double hung: upper and lower sashes can move. |
| Cleaning features | Confirm access to the fixed upper glass | Confirm which sashes tilt and the cleaning procedure. |
| Look and performance | Compare frame lines, grilles and tested ratings | Two moving sashes do not automatically mean a different exterior appearance or better efficiency. |
Hung window sizes & custom options
Start with the opening’s proportions and the height of the sill. The operating sash weight, glass selection and balance system affect the available sizes and ease of use. Do not order from the glass dimensions alone; the installer should verify the opening and installation method.
Share photos of the opening, inside and outside, along with any plans for counters, furniture, blinds or exterior access. Confirm frame colour, glass, hardware and finishing on the final order.
Compare glass and whole-window performance
Ask for the ratings of the exact size and configuration in your quote, including the frame and glass package. Compare U-factor, Energy Rating, solar heat gain and air leakage on the same basis. A centre-of-glass value is not the rating of the complete window.
Double or triple pane?
Compare the available glass packages for your opening, budget and comfort priorities. Pane count alone does not establish performance. Read the glass comparison.
Certification and written terms
Confirm current ENERGY STAR certification for the selected product. Request the written product and installation warranty, including periods, exclusions and transfer conditions. Check rebate eligibility before ordering or starting work.

What affects hung window replacement cost?
Your installed price depends on the opening size, product configuration, glass, colour, access and replacement method. Repairing framing, changing an opening or adding specialty finishing changes the scope. Compare an itemized proposal for your home rather than relying on an old starting price.
Ask for an itemized quote
- Product, glass package and dimensions for each opening
- Removal, installation method, insulation and sealing
- Interior and exterior trim, cleanup and disposal
- Repairs, permits, taxes and other inclusions or exclusions
- Payment terms, estimated schedule and written warranty
Start with a planning estimate
Use the window cost calculator to explore a budget, then confirm the final price through a measured assessment. Use the quote comparison checklist to compare the same scope between proposals.
Plan your replacement with Optima
- Review the opening. Discuss how you use the room, access, existing frame condition and any changes to the opening.
- Confirm the specification. Choose the operating configuration, glass, finish and installation scope in a written proposal.
- Prepare for installation. Agree on access, protection of the work area, expected timing and responsibility for related work.
- Review operation and care. Ask for a demonstration of locks, screens and cleaning features, and retain the warranty documents.
Window style alone does not establish egress compliance. Review the actual unobstructed opening, operation and surrounding conditions with your installer and municipal building department. Read our Ontario egress planning guide.
Operation, cleaning & maintenance
Keep tracks and weatherstripping clean, check locks and follow the instructions for balances and tilt latches. Never force a sash that will not stay in position. Keep furniture away from windows and discuss appropriate window safety measures for the household.
Hung window FAQs
What is the difference between single hung and double hung windows?
Single hung windows normally have a movable lower sash and fixed upper sash. Double hung windows allow both sashes to move vertically. Confirm the cleaning and locking features separately.
Can I clean double hung windows from inside?
Some models have tilt-in sashes. Ask which sashes tilt, how they are released and supported, and whether all outside glass can be reached safely. Follow the supplied cleaning instructions.
Are hung windows suitable for a heritage home?
Their proportions may suit an older home, but approval depends on the property and local requirements. Check any heritage or condominium restrictions before ordering. A product’s appearance is not proof of heritage approval.
Can a hung window satisfy bedroom egress requirements?
Only if the actual unobstructed opening and operation meet the applicable rules. A meeting rail and sash position reduce the usable opening. Have the selected dimensions and product assessed.
Are triple-pane hung windows available?
Ask which glass packages are available for the selected model and size. Compare whole-window ratings and operating effort as well as pane count, and confirm the final specification in writing.
