Losing your older home's charm can be difficult, especially if you have to replace its plaster ceiling. Most homeowners hold the belief that tearing down a plaster ceiling makes a house lose its character. However, since a plaster ceiling wears over time, repairs or replacement are necessary. Unfortunately, some homeowners do not know when to stop repairs and simply replace their plaster ceiling. This article highlights signs that you need a total plaster ceiling replacement.
Sagging Ceiling — When your plaster ceiling begins to sag, it can be hard to notice the change first. Ceilings often look perfectly flat and level when looked at from below. That is why you need to stand close to a plaster ceiling when inspecting it for sagging. The first thing you should do is stand on a ladder or chair at one corner of the house. Ensure that your head is almost touching one point of the ceiling for a thorough inspection. Once you are comfortable, sweep your eyes across a ceiling's surface and look for signs of unevenness. Do the same from opposite corners to get a good idea of the ceiling's condition. Notably, sagging spots could mean that the plaster has detached from the lath, increasing the cracking and disintegrating chances. If this is the case, you need to replace your ceiling.
Discoloured Plaster Ceiling — Another early sign that you need to replace your plaster ceiling is discolouring and eventual bubbling. Discolouring usually occurs when water begins to leak through a roof and settle on plasterboard and lath. A common mistake that homeowners make when they first notice the discolouration is applying a stain-blocking primer. While it hides discoloured spots, it does not address a leakage problem. As a leak gets worse, the discolouration gets bigger, accelerates a ceiling's deterioration. Notably, the bigger the discoloured patch, the sooner you need to replace a ceiling.
Delaminating Cracks — The appearance of hairline cracks on a plaster ceiling are not usually a cause for worry because they are too small to warrant structural worry. However, you should be worried about delaminating cracks because they indicate that plasterboard is pulling away from the lath. It is dangerous to occupants because a plaster ceiling can easily come crashing down as it separates from the lath. Luckily, delaminating cracks are easy to spot because they run parallel or lengthwise on a ceiling. Therefore, immediately you spot delaminating cracks, hire a roofer immediately to replace the boards and prevent possible accidents.
