But, what is some red flags we can look at with regard to interior doors, that could lead to a valid concern in a house? Well to start off, you should look, not at the doors of the house but the foundation. If there has been movement in the house or the floor are uneven this usually means that the door frames will not be square or even, which means the doors will have a challenging time closing or opening.
It is also important to take notice of the quality of the doors and the installation. If installed improperly, it could affect the energy costs and the sound containment. Other aspects that will be affected without proper installation would be the shape of the door, it could be warped, or the hardware is not functioning properly.
Another concern to be aware of is to ensure that all areas of the door are properly finished. If one of the edges is not painted or varnished (which happens often with the top of the door) this would affect the moisture intake and could warp the door over time. Another factor that raises a red flag with interior doors are the safety issues that could arise. Especially if you have kids, it would be a good idea to have pinch protection hardware installed on some of the doors in order to prevent accidents. It is also important to ensure that all doors can be easily opened and walked through, in case of an emergency.
These are some red flags that are often overlooked with interior doors.
