Best drywall pros near Greenwood, DE

While not always necessary, you can glue a drywall ceiling in addition to using screws or nails. Drywall is typically secured to ceiling joists with fasteners, which is often sufficient. However, adding construction adhesive can offer benefits like preventing sagging, bridging gaps, and reducing air leaks for better energy efficiency. It may also be used for specific acoustic or insulation needs. On the other hand, many professionals advise against it because properly placed screws make the drywall structural, glue doesn't add strength, and it makes future repairs or replacements significantly more difficult. Ultimately, it's best to follow local building codes and project-specific requirements to decide if adhesive is right for your ceiling.

Whether you need a drywall anchor depends on the specifics of your project, particularly what you're hanging and where. You do not need a drywall anchor if you can screw or nail the object directly into a wooden stud, as the wood provides sufficient support and stability. However, if there are no studs in the location where you plan to hang the item, you should use drywall anchors to ensure it is securely supported. For very lightweight objects, like small pictures, adhesive picture hanging strips can be a suitable alternative to anchors.

There shouldn’t be any gaps between your walls and ceiling. These can be fixed with joint compound but that is only a fix, and it’s much better if your drywall fits correctly in the first place. Sometimes gaps can appear if your foundation shifts significantly but if this is the case, you have a much bigger problem than patching drywall.

While a normal moisture level for drywall is between 5% and 12%, replacement is recommended if you get consistent readings above 17%. At this level, the drywall is likely too compromised by extensive moisture damage to be considered safe. You can replace either the entire sheet or just the affected section. If you are unsure after a visual inspection, it is best to have a contractor or water restoration provider use a professional moisture meter to get an accurate reading.
