"FoamCo recently insulated our basement walls. Before, we couldn’t use the basement in the winter time. We noticed an immediate difference once the insulation went in, and now our basement is our favorite cozy hangout spot in the house. They were great at explaining exactly what kind of insulation I needed and were actually the best priced bid we got."

"Why West County Insulation is the Best Choice for Your Insulation Needs When it comes to insulation, quality and professionalism matter—and that's exactly what I received from West County Insulation. Fast and Knowledgeable Service Brandon, who provided the initial quote, was timely, knowledgeable, and thorough. He explained all my options and made sure I understood everything clearly, giving me confidence in my decision. Professional and Efficient Installation The installation team, led by Andrew and Isaac, was efficient and professional. They used drop cloths to protect my home and completed the job quickly without sacrificing quality. The owner even took the time to check in after hearing about a fall I had during the job—demonstrating the company’s commitment to customer care. Great Quality at a Fair Price The insulation quality is excellent, and my home is already feeling more comfortable. With competitive pricing and outstanding service, West County Insulation offers great value for your investment. If you’re looking for reliable, professional insulation services, I highly recommend West County Insulation."

"St. Louis Insulation did a great job with insulating and ventilating both the attic and basement of our 123-year-old house in STL city.

Drywall Insulation FAQs, answered by experts

The cost to skim coat drywall is $1.15 to $1.35 per square foot. Most of the cost is labor, for the necessary skills to apply the skim coat with precision using high-quality tools. This is a job better left to the professionals for the best outcomes.

Yes, you can install drywall over plaster, but there are important factors to consider. While it can create a smooth, flat surface, it is often not the best approach. Installing drywall over plaster will increase the wall's thickness, which can cause issues with existing window and door frames that may no longer fit. You might also need to adjust power outlets to keep them accessible. A better, though more expensive, option is to remove the old plaster and lath entirely before installing new drywall. Drywalling directly over plaster seals in the old material, and if any problems arise later, you will need to remove both layers down to the structural beams for repairs. Given the potential complications, this job is best handled by professionals.

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.

There is no way to cut drywall without making dust, but you can reduce the amount of dust and especially the dangerous airborne particles by using manual cutting tools. Using a utility knife to score and snap your drywall will minimize dust production, and a jab saw for cutting cutouts for boxes and fixtures will generate almost no airborne dust. Even if you use these methods, you should still wear a respirator and safety goggles to avoid damage to your lungs and eyes.

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