Window types
Casement Windows
Casement windows are hinged at the side and open outward, offering a clear view and ventilation from an operable sash.
Awning Windows
Awning windows hinge at the top and open outward from the bottom, making them a useful option for ventilation in a range of rooms.
Slider Windows
Slider windows open horizontally along a track, providing ventilation without a sash swinging into the room or outdoors.
Bay Windows
Bay windows combine angled window sections that project beyond the exterior wall, creating a distinct focal point and bringing light into the room.
Bow Windows
Bow windows bring several window sections together in a gentle outward curve, creating a broad view and an architectural feature.
Door types
Entry Doors
An entry door helps shape the appearance and function of your home’s entrance. Choose a design, glass and hardware suited to the opening.
Sliding Patio Doors
Sliding patio doors connect indoor and outdoor spaces with glass panels that move along a track rather than swinging into the room.
Hinged Patio Doors
Hinged patio doors swing open to connect a room to a patio or garden and can be considered in single- or paired-door configurations.

|---|---|---|
| Casement and awning windows | Open outward on side or top hinges. | Allow exterior clearance for the sash. |
| Slider windows | Move horizontally along a track. | Consider the available opening for ventilation. |
| Bay and bow windows | Window sections project beyond the wall. | Check exterior space and structural support. |
| Entry doors | A hinged exterior door gives access to the home. | Review the frame, swing, threshold and hardware. |
| Sliding patio doors | Glass panels move on a track. | Consider access, track and threshold. |
| Hinged patio doors | One or more panels swing open. | Leave room for the full swing. |

Drafts and gaps
We can check seals and fit and discuss where unwanted air movement may be coming from.

Worn parts, alignment or damage can affect operation; the cause needs to be assessed first.

Condensation and water around a frame can have different causes. Tell us where and when you notice it.
