"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."

"Tim and Jeff were very fastidious in setting up, cleaning, and making sure the house was in good order when they left . We also had an Aeroseal treatment which followed with James and Connor. It did take some time to set up after the vents were cleaned and blown out, but the application of this polymer to close gaps in lthe galvinized steel ducts was remarkable."

"Had contacted another company to plow in the insulation in early December 2021 and for 3 months got the run-around from them. I contacted Ozark's Mountain Insulation and they immediately contacted me, gave me a bid and I accepted. Work done today."

"I took a while to get back to Chris and she stuck with me which I appreciate! She sent out the same rep to do the job that had come and quoted the work and he was very knowledgeable! We have noticed a big difference in the feeling of the house. Even though our house is brick they were able to provide some sort of comfort which multiple other companies refused to provide any help with. Some wouldn’t even come look."

"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 FAQs, answered by experts

While certain types of textured walls can seem dated (looking at you, popcorn), textured walls are a common sight in both older and more modern homes. The main reason textured walls may be here to stay is that they are an excellent way to hide minor imperfections on a wall and give it a finished appearance. Some homeowners think a coat of paint on drywall is a bit industrial-looking. However, that look works perfectly in modern home design. 

Whether you apply the drywall mesh before or after drywall mud depends on the type of patch it is. For self-adhesive patches, you’ll put the patch down first and then coat it with mud. Mesh patches that are not self-adhesive will require you to put mud down first and then press the mesh into it, followed by additional coats of mud.

On average, drywall installation costs around $2,000, with a typical range of $400 to $6,000, including materials and labor. The final price depends on several factors. The most significant is the size of the area, as many contractors charge per square foot. Other cost factors include the complexity of the job (e.g., cutting around multiple windows and doors, corners, or curved walls), accessibility, location, the thickness of the drywall, the height of the room, and the desired level of finish. The level of finish can range from simply hanging the drywall to taping and mudding the seams and painting the walls.

Venetian plaster is a highly durable wall finish that becomes a rock-like substance once dried, making it last longer than most other wall finishes. Its lifespan can range from decades to centuries, potentially lasting a lifetime. Key factors influencing its longevity include the quality of the initial application, whether it's properly sealed against moisture, and how the wall is maintained and treated (e.g., how often it is touched or bumped). Due to its mineral content, it can also develop a patina over time.

While fumigation chemicals cannot pass through solid objects, they will seep into any openings in walls, doors, or other closed spaces. This allows them to get into tight places where pests may be hiding and causing damage, like termites ruining the foundation of your home. It also means that your home needs to ventilate for 48 hours before returning to ensure that no harmful chemicals remain in your space.
