Weather stripping is an effective and affordable way to keep your home cool in the summer and warm in the winter. Use this guide to outline the costs, materials and other important factors.
Number of Windows & Doors
Before you purchase weather stripping materials, take note of the number of drafty windows and doors in your home. Once you have estimated the size of your project, it’s time to look at costs. Here’s what you can expect to pay per window and door:
Per interior door: $94
Per exterior door: $64
Per window: $103
According to HomeAdvisor’s True Cost Guide, most homeowners spend $243 on weather stripping their home. This is because homeowners tend to do more than one project at a time -- one door and window, two doors, two windows, etc. Check all of your windows and doors for leaks before you begin your project. Sealing multiple locations in your home at once will save you money.
