"We have an extremely small crawl space in the attic and they were able to spray in the insulation in the full attic (except the garageâ ¦donâ t know why garages arenâ t included). Love that they installed air vents prior to blowing in the insulation so thereâ s plenty of ventilation in the attic. They worked quickly and only took a few hours. We definitely can feel the difference and canâ t wait to see the difference in our electric bill."

Drywall Insulation questions, answered by experts

The two most common drywall thicknesses for ceilings are 1/2-inch and 5/8-inch. For most standard residential applications, 1/2-inch drywall is sufficient and widely used. It provides adequate support and is lighter and easier to handle during installation compared to thicker sheets. However, 5/8-inch drywall is often used for specific cases where additional benefits are needed. It is heavier but provides superior sound dampening and fire resistance. You should consider using 5/8-inch drywall for ceilings in commercial buildings, between a garage and a living space, or above a finished basement to meet building codes or for enhanced soundproofing.

To hide drywall edges, you need to properly apply drywall tape and multiple layers of joint compound. These materials hide the seams between drywall sheets and fill the holes from drywall screws, leaving behind a smooth, flat finish to paint over. Apply joint compound smoothly, and finish the job by sanding the walls to make sure you fully hide drywall edges and other imperfections.

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.

You can usually tell if you have plaster or drywall by touch (plaster is harder, colder, and smoother than drywall) or by tapping on it (drywall sounds hollow, plaster does not). If you still cannot tell, peek under an outlet cover and check the cut edges. The rough edges show the composition of the wall. You will see either drywall (two paper sheets sandwiching gypsum material) or only plaster material (no paper sheets).

You should wait at least 24 hours for drywall mud to dry before sanding or applying another coat. However, the exact drying time depends on several factors, including the thickness of the application, room temperature, humidity, and the type of compound used. Thicker layers, or projects in high humidity, may require 48 hours or more. Lightweight compounds tend to dry faster than heavier, all-purpose ones. You'll know the mud is ready when it feels completely dry and firm to the touch and has changed to a consistent light color. Sanding too early can cause smudging or gouges, so patience is essential for a smooth finish.
