Glass Repair Danforth

Casement Windows – Hinged on the side and operated via a crank, these windows open outward for maximum ventilation. Ideal for hard-to-reach areas like above sinks, they create a seal when closed, enhancing energy efficiency. Common in modern homes, they often feature reinforced vinyl or aluminum frames. Issues may include hinge corrosion, crank mechanism failures, or sealant degradation leading to drafts.

Awning Windows – Top-hinged and opening outward, these windows allow airflow even during rain, making them perfect for bathrooms and coastal homes. Constructed with durable, weather-resistant materials like fiberglass, they can suffer from hydraulic arm malfunctions or hinge misalignment over time.

Hopper Windows – Bottom-hinged and tilting inward, these are commonly used in basements for ventilation and emergency egress. Their inward tilt prevents debris accumulation but may pose challenges in cleaning exterior surfaces. Issues include faulty latches or compromised seals leading to moisture intrusion.

Double-Hung/Single-Hung Windows – Double-hung windows feature two movable sashes for versatile airflow control, while single-hung only allow the bottom sash to move. Popular in traditional homes, they may use spring or weight-and-pulley systems. Common repairs involve replacing broken sash cords, rebalancing springs, or addressing paint-sealed sashes that hinder operation.

Sliding Windows (Gliders) – Horizontal sliding panels on tracks offer low-maintenance operation and sleek aesthetics for wide openings. Issues include track debris buildup, roller wear, or misalignment causing air leaks. Modern versions often include tilt-out sashes for easier cleaning.

Tilt-and-Turn Windows – A European staple, these dual-function windows tilt inward at the top for ventilation or swing fully inward for cleaning. Made with uPVC or thermally broken aluminum, they excel in energy efficiency but may face seal failure or hinge mechanism jams.

Fixed/Picture Windows – Non-operational and designed for unobstructed views, these are ideal for living rooms or as architectural focal points. Framed in vinyl, wood, or fiberglass, they risk condensation from failed insulated glass unit (IGU) seals or structural stress cracks.

Transom Windows – Mounted above doors or larger windows, these narrow units add light and style. Operable versions use hinges or pivots for airflow but may suffer from seal degradation or hinge squeak.

Jalousie Windows – Comprising horizontal glass louvers cranked open in unison, these are common in tropical climates for maximum airflow. However, poor insulation and vulnerability to louver mechanism breakdowns limit modern usage.

Bay Windows – Angled projections with three or more panels (often combining casement and fixed units) create interior nooks and panoramic views. Structural issues include frame sagging or seal failure at joints. Reinforced vinyl or wood frames are typical.

Bow Windows – Curved with four or more panels, these offer a softer aesthetic than bay windows. Installation challenges involve aligning curved tracks and maintaining thermal seals across multiple IGUs.

Arched Windows – Featuring a curved or semicircular top, these add Gothic or Roman elegance. Fixed or operable, they require precision sealing at the arch’s apex to prevent leaks.

Circle/Octagon Windows – Geometric designs serve as decorative accents. Installation demands custom glazing and specialized framing to prevent stress fractures in tempered glass.

Clerestory Windows – High-placed horizontal bands flood interiors with indirect light. Operable versions in modern homes may use remote-controlled motors, risking sensor or wiring issues.

Garden Windows – Projected glass boxes with shelves for plants, often found in kitchens. Vulnerable to leaks at the projection joints or condensation from humidity.

Corner Windows – Two windows meeting at 90° for panoramic views. Structural reinforcement is critical to prevent settling-induced cracks at the corner junction.

Ribbon Windows – Horizontal bands of multiple windows (mid-century modern) require precise alignment and uniform seals to maintain energy efficiency.

Palladian Windows – A grand arched center pane flanked by smaller rectangles. Structural support for the arch and sealant integrity are common maintenance items.

Egress Windows – Code-compliant emergency exits with minimum opening dimensions for basements/bedrooms. Steel or vinyl frames with tempered glass ensure safety but may face latch failures or water intrusion.

Skylights – Roof-installed for natural light; vented versions offer airflow. Risks include condensation buildup, seal failure, or flashing leaks. Tubular skylights use reflective ducts but require precise angle alignment.

Storm Windows – Secondary exterior panes for insulation or hurricane protection. Installation challenges include aligning with primary windows and maintaining airtight seals.

Soundproof Windows – Laminated glass with acoustic seals reduces urban noise. Degraded seals or frame gaps compromise performance.

Impact-Resistant Windows – Laminated glass and reinforced frames meet hurricane codes. Common in coastal areas, they require regular inspections for frame corrosion or sealant wear.

Fire-Rated Windows – Ceramic glass and steel frames compartmentalize fires. Maintenance focuses on intumescent seal integrity and hinge functionality.

Storefront Windows – Commercial-grade floor-to-ceiling glass with aluminum framing. Anti-graffiti coatings and laminated security glass are standard; repairs often address scratches or sensor alignment in automatic entries.

Pass-Through Windows – Openable kitchen or service windows (e.g., bars). Issues include hinge wear, seal degradation, or hygiene concerns in food-service settings.

Mirrored Windows – One-way reflective glass for privacy/solar control. Coatings degrade over time, requiring careful cleaning to avoid scratches.

Low-E Windows – Microscopic coatings reflect UV/IR rays, reducing energy costs. Over time, coating degradation or seal failure can diminish performance.

Triple-Pane Windows – Triple glazing with argon/krypton gas minimizes heat transfer. Thicker frames and gas retention are critical for longevity.

Gas-Filled Windows – Argon/krypton between panes enhances insulation. Gas leakage, detectable via fogging, necessitates IGU replacement.

Pivot Windows – Rotate on a central axis for unique ventilation. Balance adjustments and hinge lubrication are key maintenance tasks.

Automatic Windows – Motorized operation in smart buildings risks sensor malfunctions or power supply interruptions.
