"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."

"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. Zac was very knowledgeable and helpful and the service was affordable. The job was done quickly and efficiently. I highly recommend them for any insulation needs in the city."

"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.

"The BATH UPSTAIRS   had a window that needing bracing, a bath that had black mold behind the horrible VINYL wall, and had to be insulated with MOISTURE proof materials and RE-TILED - the walls, under the window and behind the tub and around the laundry chute opening.  The Downstairs Bath also needed the window braced and tiled as it was falling and splitting from the ceiling due to POOR WORKMANSHIP by someone NOT on Angies List back in 2003!!   SO, Siding Repair Systems -  They did it all, with their contractor Thomas Morton.  What a really fantastic job - on BOTH these Bathroom windows, Tiling and securing/supporting.  EXCELLENT WORK!!  Clean and neat - it looked like they had a MAID SERVICE come in and clean up after them.  Honestly.  So neat and clean they were.  Thanks for a Really good job.   "

Insulation questions, answered by experts

You should not use spray foam insulation in several specific areas. Avoid applying it in spaces exposed to high temperatures, such as near electrical boxes or recessed lighting, unless the foam is specifically rated for such use. Applying foam near electrical boxes can damage the wiring, and using it too close to lightboxes or recessed lights creates a potential fire hazard. Additionally, do not use spray foam in areas prone to shifting or movement, as this can lead to cracks and gaps in the insulation. Finally, open-cell foam is unsuitable for use below ground or in areas exposed to moisture because it can absorb water, which compromises its insulating effectiveness.

Water freezes at 32 degrees Fahrenheit, but the actual temperature that can cause frozen pipes can vary. Generally, it takes 12 hours for pipes to freeze at 32 degrees Fahrenheit.

Uninsulated pipes can freeze if it’s 20 degrees Fahrenheit or colder for over three hours. If your pipes are insulated, it can take six hours or longer for pipes to freeze. Note that some pipe types freeze more often than PEX pipes. Copper pipes freeze more often because the copper conducts energy and loses heat quickly.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

Your home's location, budget, and the type of insulation you’re using are just a few of the factors that can help you choose the right insulation. For example, blown-in insulation is typically used in attic spaces, while batts and rolls are ideal for floors and walls. Blown-in insulation is usually a good option if you're adding more insulation to an area that already has some, but not enough.

Yes, you can use too much bubble wrap. If you overdo it with the wrapping, it can strain the top of your box and break open the taped seal, risking the chance that the contents of the box could fall out or break. Use enough wrapping to fully cover your item without compromising the security of your box.
