"Edgar listened to my request to perform the tasks of insulating the HVAC ductwork and hotwater lines before installing the R30 batts in the joists. He did a good job in cleaning up the fallen insulation pieces from the floor, but there was still residual insulation dust on the floor and on my storage boxes. The tape he used to secure the ductwork insulation batts kept coming undone after he left, which I later re-taped myself. Overall, the quality of the work was great, but the cleanup could only be rated as 'Good'."

"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

"They are a very professional organization. Their workmen do a very good job and an excellent job of cleaning the area before they departed the job site. I can tell immediately that the extra insulation they placed in the attic is doing its job by reducing our utility bills."

Drywall Insulation FAQs, answered by experts

Plaster walls typically last between 30 and 70 years, but depending on the quality of the materials and the moisture levels in the building, they can last for over 100 years. With expert application and consistent maintenance, plaster can even last for centuries. To extend its lifespan, it is important to have the plaster professionally installed, address any water damage promptly, and repair small cracks as they appear. Regular inspections by a professional can help identify and address concerning cracks before they become significant issues.

Applying plaster to a wall will usually cost between $2 and $10 per square foot for both the material and labor. The cost will vary based on the quality of the plaster you’re using and whether or not prep work is required before the work begins. Wall prep can add up to about 10% to your total costs. Plastering exterior walls can be more expensive in many cases because they are taller and require scaffolding and safety equipment.

Drywall can be toxic to the environment and to humans in some cases. As drywall breaks down in a landfill and comes in contact with other organic chemicals, it can create hydrogen sulfide gas or leach into the groundwater. Additionally, the CDC recommends methods for controlling the inhalation of drywall dust when handled. While the common ingredients of drywall—gypsum, silica, and mica—are naturally occurring, they can cause irritation in some humans.

You can take a few steps to save money on drywall installation, even when hiring a professional to do the bulk of the work for you. These ideas include the following:

  • Buy the drywall and other materials yourself to avoid product markup and delivery fees

  • Ask about discounts if you use the same company to tape, spackle, and paint

  • Hire drywall professionals in the winter when demand is the lowest

  • DIY as many parts of the project as possible, like replacing insulation and painting

There are a few ways to figure out if your walls are plaster or drywall, but the pushpin method is probably the easiest option. To try it, choose a part of your wall where you can insert a pushpin or thumbtack without leaving an obvious mark. If it goes in easily, you have drywall. But if the wall is tough to penetrate, that’s plaster.
