You don’t have to be a construction expert in order to realize that doors and windows are some of the most complex elements of a building’s exterior and that is why they need to be properly inspected as following:
Exterior Doors Inspection
When it comes to examining exterior doors, they need to be checked for their hardware functionality, overall fit and operation, but also their condition. There are many types of doors including glazed and non-glazed doors, aluminum, doors, steel doors, double and single wooden doors, but also hinged doors.
When checking the plastic and wooden doors, make sure that they are properly protected from the elements. They should also be rated for external use.
In warmer climates, most people will choose to use jalousie doors which need to be checked carefully to ensure that the louvers not only close in unison, but also able to offer adequate weather protection.
There are many buildings that can also use glass framed doors of operable and fixed panels that feature aluminum, vinyl covered wood, but also wood frames. In this case, you need to carefully inspect the track of the siding doors and make sure they are straight and that they’re free from breaks and dents. Take note of the doors’ locksets and degree of physical security and carefully inspect pairs of sliding and hinged doors.
The doors need also have the condition of their sills and frames inspected in order to ensure that they are protected against the elements and that there is no risk of flashing. In a hurricane region, make sure to check the double doors and exterior doors and make sure they have dead bolt locks with a throw length of minimum 1′.
When examining windows, you need to inspect the condition of the sashes, sills, frames and their overall fit and operation. The interior inspection is when the windows’ hardware and overall condition will be properly assessed.
In residential buildings, inspectors may come across up to six kinds of frame materials and 8 types of windows. To name the type of materials used for the frames, they are metal clad wood, plastic clad wood, wood, but also steel, aluminum and of course, plastic.
The variety of windows to be inspected can range a lot and it includes fixed windows, outer awning windows, horizontal sliding windows, casement windows, but also single hung and double hung windows. On top of these types, there are also jalousies which are basically louvers made of glass on either a steel or aluminum frame.
The most vulnerable part of a window is the glazing around the glass panels and that is why it needs to be inspected very carefully, since repairing it is very time consuming.
Glazing strips and tapes around glass panels in aluminum or steel sashes should be patiently examined since they may indicate deterioration such as poor fit or hardened sealant. The metal sashes should be checked for weep holes which have been blocked by dirt, sealant or paint. The good news is that if they’re clogged, cleaning them is very simple.
Windows that aren’t protected against the elements should be checked for the presence of essential flashing at the head. If the windows are accessible from flat roofs or close to the ground, the inspector should take note of how secure they are, including their locks.
If inspecting the windows in a hurricane area, the inspector should take note of the ones that aren’t protected by shutters.
Geographical location also plays important role, maybe not in a way the windows should be inspected, everything above still applies, but in overall expectations of the window condition. You should expect the condition of a 10 year old wood window in Florida where the temperatures are staying above freezing (well, almost always) to be much better than the condition of an identical window in Northern parts of US. For a 10, maybe 15 years old unit without proper maintenance window replacement might be necessary.
Door weather and window stripping fall into 3 types, including plastic, foam plastic or metal stripping and each of them should be checked for fit. Plastic stripping needs to be checked for cracks and brittleness, foam plastic should be checked for resiliency and metal needs to be inspected for straightness, bends and dents. Also, the weather stripping should be held in place securely.
There are 2 types of shutters, including functional and decorative shutters. Make sure to check the shutters’ mounting to the wall and their condition.
Next, you need to assess how accurately the shutters meet their purpose, including protection against the elements, security, light control and privacy. Try to operate them and see if they work properly.
In a hurricane region, make sure the shutter are certified for hurricane use. If they also provide protection to glass doors and windows, make sure they were tested for windborne debris and impact resistance.
Sometimes, glazed exterior doors and windows feature awnings over them to control the amount of sun entering the property, but also for decoration purpose. In terms of materials, awnings are generally made of plastic, metal or fabric on a plastic or metal frame.
While some of them can be easily folded against the external wall, others are fixed in place. Carefully check their condition and try to operate them to see if they work properly.
Storm Doors & Windows
When it comes to storm doors and windows, they need to be assessed for their overall fit, condition, weather tightness and operation. Carefully check the condition of the glass and screen inserts. Take a good look at the weep hole as well and see if they’ve been blocked by dirt, sealant, paint or other types of debris.
Check the overall condition of the garage doors, but don’t forget to check for weather tightness, fit and operation as well. Doors with motors should be operated using the provided remote control while motorless garage doors need to be operated manually. The operation in both cases needs to be safe, swift, quiet and smooth. Check the door safety reversing device and take note of damaged or bent pieces, rust or loose connections.
Hardboard or wooden garage doors should be checked for rotting, splitting and cracking, steel doors need to be checked for rust, aluminum doors for bents and glass fiber doors for UV light deterioration.
In a hurricane area, make sure the assembly was reinforced or tested for wind loads or hurricanes.
Glazed entrance doors, such as sliding glass patio doors, storm doors, excluding jalousie doors need to be adequately wired, completely tempered or laminated glass or any other type of approved material. On top of that, glazing adjacent to any other surface that is generally used for walking needs to be safety glazing.
