"They are supposed to come tomorrow, they agreed on that. They called and told me that the job is too small and they refused to do the job. Meanwhile I described the job to the woman, the dimensions and the specifics and she agreed but still cancelled it."

Insulation questions, answered by experts

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.

Yes, cold walls could indicate that your home has poor insulation, especially if the walls are significantly colder than the air or other areas in the home. In most cases, cold walls are a sign that the heat produced by your furnace isn’t hanging around long enough to make the walls warm. If that’s the case, hire a local HVAC technician to take a closer look at your heating system.

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.

Homeowners insurance covers some damage caused by ice dams, but it depends on the type of damage. Insurance policies will often cover things like interior water damage, roof collapse, and actual shingle damage resulting from ice formation, but it depends on your policy. Check your coverage information or contact your insurer to find out what your plan covers. Keep in mind that any damage caused by implementing a DIY solution to remove ice dams likely won’t be covered.

The average cost to install insulation is around $1,800, but you could pay anywhere between $500 and $4,500, depending on various factors. Some of the things that have a significant influence on your pricing include the following:

  • Size of the area 

  • Type and R-value of the insulation 

  • Whether your space is finished or unfinished

  • Accessibility of the area

  • Your geographical location

  • Amount of site preparation, especially for blown-in insulation

  • Whether or not you need old insulation removed
