A: You have three problems that may or may not be related. Condensation is a sign of excess moisture in the house. The first thing is to try to determine the cause. It may be a washer or dryer not properly vented to the outside, or it may be standing water under the house.

Other reasons may be indoor plants or an aquarium that's adding moisture to the home. If you can eliminate an obvious cause, you may solve your problem.

Sometimes the cause is not so obvious, in which case installing new vinyl or wood frame dual pane windows with spectrally selective glass may end the problem of condensation showing up on your windows.

As far as the water spots, it sounds like you have a roof leak or flashing problem. To solve the sparse insulation around the perimeter of your attic, you need to add baffling blocks to the vents and insulate. You can definitely benefit from a professional inspection of all these problems.

To locate some window, insulation and roofing professionals to come inspect your home and make recommendations, visit Home Advisor, submit service requests for the appropriate repairs, explain the related problems, and be matched with the ideal service professional in your area.
