"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."

"Chris with St. Louis Insulation went above and beyond, he dispatched Brian out to inspect our insulation as we thought it was getting wet on the same day we called. Ultimately it was determined we did not have an issue. If an issue ever does come up we will be calling Chris with St. Louis Insulation. Thanks, Russ"

"He was very knowledgeable and professional. After the audit we received an estimate to correct any areas that were discovered. Unlike what we originally thought our issues were not the windows and doors. The estimate was for $4000 to add insulation to the attic, increase airflow in the attic, install foam insulation around our fireplace and throughout the basement as well as removing the attic fan and adding drywall. 
The price is the estimated price for projects to be completed.

"I’m a land lord of 72 residential properties and the biggest head ache other than common upkeep was the constant battle with roaches and insects inside the units, I had Triple B come out and put their pest control infused insulation at 10 of my properties and within 3 weeks the tenants were in shock at how affective it was, they went from seeing them everyday to hardly ever, I ended up getting them to do all my units and also my own house, this will be a must at any property I ever purchase, highly suggested for new home owners/buyers"

Drywall Insulation questions, answered by experts

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.

Yes, any parts of drywall that are wet or overly moist will need to be replaced. Drywall is intended to be dry (it’s in the name, after all.), as excess moisture can lead to mold and mildew and eventually corrode your home’s foundational building pieces. Do regular inspections in your home to make sure all your plumbing is intact and in good condition—this will go a long way toward preventing leaks.

The easiest way to cut holes in drywall for electrical boxes is to use a spiral saw with a drywall router bit. Hang the drywall without cutting out a hole for the box, but make sure you measure and mark where the box is located on the wall. Once you screw in the drywall sheet, drill a small hole into the box void, insert the spiral saw bit, and move it around the edge of the box using the inside wall as a guide. You can also use an oscillating multi-tool with an electrical box cutout for fast, professional results.

Whether to repair or replace water-damaged plaster depends on the scale of the damage. For small, limited areas, you can often perform a repair yourself. If you choose to paint over small patches, ensure the surface is completely dry and apply a coat of antifungal primer first to prevent mold growth. However, simply painting or plastering over the damage is only a temporary solution that doesn't address the core problem. For more extensive or long-term damage, the plaster may be compromised, and there is a risk of mold. In these cases, it is recommended to remove the damaged section of plasterboard and replace it. You may consider hiring a professional for the repair, and it's worth noting that water damage is often covered by home insurance.
