"I really liked CT Basement systems. The sales rep walked me through the process of the basement SaniDry I had installed. When the installer came it turned out that I didn’t need all of the duct work and I was able to save a few hundred bucks. The installer was very professional, neat and helpful . I definitely will hire this company again. Customer service even followed up with me a few days later and had to remind me to register the system (good thing because I had forgotten)."

Insulation questions, answered by experts

No, 55 degrees Fahrenheit is not too cold for a house, as it’s a temperature that will keep your pipes and appliances from freezing. Well-insulated homes can even go to 50 degrees, but check with an HVAC pro before opting for such a low temperature. Stick to 55 degrees to be on the safe side.

Yes, cold walls are a common indicator of poor or inadequate insulation, especially if the walls feel significantly colder than the air in the room. This suggests that heat from your furnace is escaping rather than being retained. The issue could be that the walls have no insulation, or that the existing insulation is old or has been damaged by water, moisture, or pests. Your best course of action is to hire a professional to investigate. An insulation contractor can determine if you need to add or replace insulation and can often perform the work without creating large holes in your drywall. If you suspect the problem might also be related to your heating system's performance, an HVAC technician can take a closer look.

The most energy-efficient windows are double—or triple-pane windows with low-emissivity (Low-E) coatings and gas fills between the panes. These windows reduce heat transfer, prevent drafts, and help maintain a consistent indoor temperature. But if replacing windows isn’t in your budget, pairing your existing windows with insulating window treatments can still make a noticeable difference in home comfort and monthly bills. 

For a DIY solution to protect an outdoor faucet from freezing, you can craft a cover using spare rags, a durable plastic bag, and duct tape. However, be aware that this method may not be as effective as a store-bought cover. Fabric like rags or old towels can absorb water, which could freeze and cause problems. While a DIY cover can work as a temporary stopgap, a proper outdoor faucet cover is inexpensive (often $5 or less), easy to install, and readily available, making it the recommended long-term solution.

Closed-cell spray foam insulation itself serves as a vapor barrier (or vapor retarder). However, you may need to install a vapor barrier if you have open-cell spray foam insulation. When in doubt, work with a professional insulation contractor, as they can provide more detail about the specific needs of your home in your climate.
