Doorbell Installation questions, answered by experts

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.

If you feel your energy bills are too high or your HVAC system is working harder than necessary to maintain the correct temperature in your home, you may have an under-insulated home. If you’re unsure, consider having your system’s efficiency assessed by a local independent energy auditor.

DIY insulation installation is feasible, particularly for basic rolls or batts, if you have the right protective gear and knowledge. However, hiring a professional ensures even, full coverage for maximum efficiency.

If you’re a savvy DIYer around the house, own the basic tools, and have enough time on your hands, you can definitely install fiberglass insulation yourself. Doing the work yourself will certainly keep overall insulation costs down. However, if you’re not confident in your handy skills around the house, call in a professional.

Insulating your home's exterior walls can realize up to a 20% reduction in your monthly energy bills. This means that regardless of how much the project costs, it can begin to pay you back immediately. Additionally, adding spray foam and other high-end materials can increase the selling value of the property.
