Frequently asked questions

Everything you need to know to start your project.

Who needs single hung window replacement and why?

Single hung windows are a timeless choice for many Toronto homeowners, but over time, their mechanisms and seals can deteriorate. If your home still has older single hung windows, replacement may be necessary for both comfort and efficiency.

When replacement is needed:

  • Drafts or condensation appear between panes.

     

  • Difficulty opening or closing the bottom sash.

     

  • Visible frame rot or water infiltration.

     

  • Increased noise or heat loss from weakened seals.

     

Modern TotalSeal single hung windows eliminate these issues with new-generation sealing systems, fusion-welded frames, and multi-chamber insulation.

What are the structural features of modern single hung windows?

Modern single hung windows feature a fixed upper sash and a movable lower sash, offering vertical ventilation and compact functionality.

Key structural elements:

  • Reinforced frame with fusion-welded corners for maximum rigidity.

     

  • Vertical sliding sash that moves smoothly on metal or vinyl tracks.

     

  • Balancing mechanism (spring or block-and-tackle) for effortless lifting.

     

  • Tilt-in cleaning option for easy maintenance.

     

  • Weatherstripping and interlocks for superior sealing and noise reduction.

     

TotalSeal’s single hung systems are engineered for durability, combining simplicity with advanced insulation.

How does replacing single hung windows affect thermal insulation and comfort?

Replacing outdated single hung windows significantly improves thermal performance and reduces air leakage.

Replacing old single hung windows leads to better heat retention, fewer drafts, quieter interiors, and lower energy bills.

What should be included in a full-service single hung window replacement project?

A complete replacement service includes everything from removal to finishing — ensuring no air leaks, no moisture intrusion, and a clean aesthetic.

Full project breakdown:

  1. On-site measurement for custom-fit fabrication.

     

  2. Safe removal of existing frames and glass.

     

  3. Opening prep – leveling, cleaning, insulation.

     

  4. Installation of new frame and sash using precision anchors.

     

  5. Perimeter sealing with foam and silicone caulking.

     

  6. Interior & exterior finishing – trims, caps, paint-ready joints.

     

  7. Final quality inspection for air-tightness and balance.

     

TotalSeal guarantees every stage is completed to factory-level precision.

What are the pros and cons of single hung windows compared to double hung?

Both styles share similar aesthetics, but differ in operation and maintenance. Single hung windows are ideal for those prioritizing cost, simplicity, and energy savings.

If ventilation from both ends isn’t critical, single hung models deliver better sealing and lower cost while maintaining a sleek look.

How often do single hung windows require maintenance and adjustment?

Single hung windows require very little maintenance — but periodic care ensures long-term performance.

Recommended schedule:

  • Clean tracks and sashes every 3–6 months.

     

  • Lubricate pulleys or balance springs once per year.

     

  • Check and replace seals every 5–7 years if needed.

     

  • Inspect locking mechanisms for tight closure annually.

     

Simple upkeep helps maintain smooth operation and energy efficiency for decades.
