"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"

"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"

"The fellows did a great job with this house.  The work is really quite excellent, and they kept us informed with how long it would take, how it was going, and could speak in understandable sentences.  They were polite and they worked very quickly.  
We were amazed and how quickly they did this job, as it was perfect and not at all sloppy, which you easily see in others who are quick and sloppy.  They were anything but.   They cut around several outlets and exterior items on the house and that was done well.  I would definitely recommend to anyone.  We also cannot believe how much WARMER THE BACK OF THE HOUSE is now - especially as it faces NORTH and was quite cold for the last 15 years.  We hope to be able to have them do the rest of the house as we like the insulation put in and the type and quality of siding that was used.  We would recommend most definitely."

Insulation questions, answered by experts

If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install blown-in insulation. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than $100. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.

Winterizing your outdoor plumbing keeps your outdoor spigot from freezing and potentially bursting. This includes draining residual water out of the pipe and spigot after turning the valve off, then removing garden hoses and other attachments from the spigot before winter comes. Insulating the pipe that leads to the spigot and installing a freeze-proof faucet also help, as does installing an outdoor faucet protector.

Reduces energy costs, improves comfort, and prevents ice dams in winter.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

The most insulative type of insulation for behind drywall is spray foam insulation, but this is the most expensive insulation available. The most common insulation—sometimes considered the best for the value you get for the money—is fiberglass roll or fiberglass batt insulation, which is significantly more affordable but also far less insulative. The best kind of insulation for your house will also vary based on the climate in your area, your budget, and more. A professional insulation company can help you decide which type is best for your home.
