"I contacted Osvaldo to repair drywall in my ceiling after water damage, and I couldn’t be more pleased with the results. From the start, they were professional, responsive, and punctual. They quickly assessed the damage, explained the repair process clearly, and gave me a fair and transparent estimate. The quality of the work was outstanding. The ceiling looks like new—seamless and perfectly blended with the surrounding area.They were meticulous with cleanup too, leaving the space spotless when they finished. It’s clear they take pride in their work and care about customer satisfaction. I highly recommend Osvaldo to anyone in need of drywall repair. I’ll definitely be calling them again for future projects!"

"The professionalism and quality that the Insulation Labs team demonstrated from beginning to end should serve as a Master Class for any other service oriented company. Scheduling the estimate was effortless with clear, helpful and efficient communication from Diana, their first line of contact. Abraham arrived to do the estimate visit with kind patience and knowledge. He took the time to help us figure out how best to approach the insulation and was more than willing to answer all of our many questions. When we received the estimate we were appreciative of how easy it was to read and understand what the plan was. We knew exactly what to expect and how much it would cost. Today was the day of the insulation. Chris, Tzoc, and Moises spent a long full day doing the entire job. Throughout they were kind, professional, and did an outstanding, neat job. At all times, they cared for our space as if it were their's. We are so glad we chose Insulation Lab. There is no question we would recommend them to anybody."

Drywall Insulation questions, answered by experts

Both plaster and drywall are durable wall finishes, but they differ significantly in installation, cost, performance, and aesthetics.

Installation & Cost: Drywall installation is faster and more affordable, typically costing $1.50 to $3 per square foot. It uses premade sheets, making it a more accessible DIY project. Plastering is a labor-intensive craft that requires specialized skills, pushing costs to $2 to $10 per square foot. It involves applying a wet paste over a lath framework.

Durability & Performance: Plaster is generally more durable, longer-lasting, and provides superior soundproofing. It is also a better insulator, which can help reduce energy costs. Drywall is easier to remove for future renovations.

Aesthetics: Drywall provides a smooth, uniform surface ready for paint or texture. Plaster offers a high-end, naturally textured look that can hide imperfections and is often preferred for achieving a classic or historic aesthetic.

Which is better? The choice depends on your priorities. Drywall is ideal for those prioritizing a lower upfront cost, faster installation, and DIY potential. Plaster is the better option for a higher-end project where durability, soundproofing, and a unique, premium finish are more important than the initial cost.

Costs depend on damage size, labor rates, and whether additional services like painting are required.

Yes, it is possible to rewire a house without removing the drywall, but this doesn’t work in all homes. You can pull out old wires and insert new ones if you have access to the wiring system via the ceiling or through a crawl space. Some pros can also use a magnetic kit to fish the old wire out of the wall through a hole cavity and install the new wires. Just keep in mind that doing this is less stable than removing drywall, as you won’t be able to staple the wires into the framing.

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.

There are several things you should not do when installing drywall. Common mistakes include: adding too many screws, over-sanding, not adding backing support, and installing drywall unevenly. You also should avoid screwing into the same place twice, installing Sheetrock with tapered edges on the outside, and making too many joints.
