Very nice, was on time. Work was done well. Two exhaust fan replacements hook up new doorbell & one light in utility room took the most time. Replacement of one socket & one two way switch & two replacement lights in garage. We thought for the work done price was a little excessive.

Doorbell Installation questions, answered by experts

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house.

Yes, including recycled denim and cellulose from natural fibers.

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.
