  • Great as a living room focal point

Casement Window

  • Compresses shut for a tight seal
  • Strong fit for a main window

Awning Window

  • Top-hinged, opens from the bottom
  • Ventilates even in light rain
  • Popular above sinks & in bathrooms
  • Pairs well below a picture window

Slider Window

  • Opens horizontally on a track
  • Simple, budget-friendly
  • Common in SoCal tract homes

Single & Double Hung

Patio Doors: French vs. Folding vs. Sliding

  • Sliding: the most opening width for the least cost — the most popular choice
  • Folding: opens nearly the entire wall — the most dramatic indoor-outdoor connection, ideal for entertaining spaces
  • French: swings open on hinges for a classic look — open just one panel for airflow, best for older or character homes

FAQ

Buying Guide Questions, Answered

What's the difference between a bay window and a bow window?

A bay window has 3 panels — a fixed center pane flanked by two angled operable windows. A bow window uses 4 to 6 panels in a gentler curve, projecting out further and adding more usable interior floor space. Bow windows read as bigger and more dramatic; bay windows are a bit more compact and typically cost less.

Should I choose casement or awning windows?

Both crank open and seal tightly. Casement windows hinge on the side and open like a door, giving the widest possible ventilation opening — a strong fit for a main window. Awning windows hinge at the top and open outward from the bottom, so you can ventilate even during light rain, which makes them popular above sinks, in bathrooms, or paired below a picture window.

What's the difference between slider windows and single/double hung windows?

Slider windows open horizontally, sliding side to side — simple, budget-friendly, and common in Southern California tract homes. Single and double hung windows slide vertically instead; in a double hung both sashes move, which also makes them easier to clean from inside. Hung windows suit traditional or Craftsman-style homes, while sliders fit a wider range of modern openings.

Should I get French patio doors, folding patio doors, or sliding patio doors?

Sliding patio doors give the most opening width for the least cost and are the most popular choice. Folding patio doors open up nearly the entire wall for the most dramatic indoor-outdoor connection, which suits entertaining spaces. French patio doors swing open on hinges for a classic look and let you open just one panel for airflow, which fits older or character homes best.

Which window style is the most energy efficient?

Picture windows are typically the most energy efficient because they're fixed and have no moving hardware to seal, so there's less opportunity for air leaks. Casement and awning windows seal tightly too because they compress shut like a door. Slider and hung windows rely on a track seal, which can loosen over time.

How do I know which window style is right for my home?

It comes down to the room, the view, and how much ventilation you want — a kitchen sink often calls for a garden or casement window, a living room benefits from a bay or bow, and bathrooms do well with awning windows. Guy and Adam walk every homeowner through the options in person during the free on-site consultation and help you pick the style that fits the opening and your budget.
