drywall services in TorontoDrywall is the skin of a building, fastened over the bones of its framework; it can help conceal defects in the framing when well done, but a poor drywall job will not only reveal defects, but create the appearances of flaws on a perfect structure. Drywall, also known as sheetrock, took the place of plaster and lath in finishing walls and is used in the vast majority of homes today. For better property values and simple aesthetics, drywall needs to be installed with precision and planning.

Elements of a Good Drywall Job

Judging the quality of drywall installation can be difficult without experience, but a basic checklist will help ensure a thorough inspection. A good job will have used adhesive and enough screws. It will have tight joints, each placed even with its neighbors, with no gaps. Butt joints will be staggered and clean, with no sign of ragged edges. No gaping holes will be present, and outlets will be cut to the proper size, with only a few cut overly large. Outside corners will not have factory edges meeting, and corner bead will be placed with sufficient space for joint compound. Good planning will be in evidence, with large boards to provide minimal joints that are placed with efficiency and finishing in mind.

Testing the Quality of a Drywall Job

While most factors of excellence in drywall hanging can be judged with a simple visual examination, a complete inspection requires some tests. One is to check for use of adhesive. The only tool required for this test is a fist. Simply thump the drywall over the studs and listen for rattling or the impact of drywall against the studs, which indicate a gap. Glued-on panels will sound solid when this test is performed.

Another simple test can check for protruding screw heads. To do this, take a 15 centimeter joint knife, place it against the wall at a 45-degree angle, and drag it over the screws with just enough pressure to create a slight bend in the blade. Listen closely while doing this; a distinct clicking sound will indicate a screw that is not properly recessed.

Types of Drywall

Basic drywall, also known as sheetrock, wallboard, and gypsum board, is the most commonly used panel in the standard drywall job. Lesser thicknesses are especially common in ceilings, although they are also sufficient for most walls. Special circumstances call for special types of drywall, however, and several specialty types are available for extra benefits. One example is the most expensive type of drywall: fire resistant drywall. Also called fire board, it is extra thick and used where codes require fire resistance ratings. In addition to being non-combustible, it is also soundproof.

Moisture Resistant Drywall

Moisture resistant drywall, also known as greenboard, boasts special surface coatings to create that resistance. It is mainly used in utility rooms, bathrooms, and basements. This type will not warp in damp conditions like standard drywall will.

The right type of drywall is essential for a proper look and greater property values. With basic knowledge of the types of sheetrock, an eye for proper size and placement, and the indications of excellence in a drywall job, anyone can ensure successful results.
