FAQs

  • Introduction

    Properly caring for doors and windows is a big part of keeping a home looking its best. However, finding the right approach to maintenance, repairs, and replacement isn't always easy. These frequently asked questions can provide insight into how to best care for doors and windows, including how to purchase, install, replace, paint, and clean windows and doors throughout a home.

  • How do you paint a front door?

    To paint a front door, all hardware should first be removed. Then, the door should be sanded and cleaned before a coat of paint can be applied. For best results, use an exterior-grade paint-primer combination. Place a drop cloth before painting to prevent damage to flooring.

  • How can you paint a front door without brush marks?

    The best way to paint a door without brush marks is to avoid using a brush. A paint roller can be used to paint most surfaces on a door. A small brush may be required to touch up small areas that a paint roller can't reach.

  • What are some ways to pick an excellent front door color?

    Picking a paint color is largely about aesthetics and preferences. Consider factors like the exterior of a home, landscaping, and colors that are used elsewhere in the home. Reds, blues, and greens can be lovely accent colors, and white and gray go with almost anything.

  • What paint do you use to paint a front door?

    Always use an exterior-grade paint on front doors. Paints used for interior walls aren't designed to withstand heat, rain, snow, sleet, or hail and will likely peel or fade quickly if used outdoors. Using a paint-primer combination can minimize the amount of coats required to fully paint a front door. 

  • How do you keep mosquitoes away from the front door?

    Installing a screen door is among the most effective ways to keep mosquitoes away. Homeowners can also remove any standing water near the door, keep grass cut short, plant mosquito-repellent plants, and use mosquito lights to prevent unwanted invaders.

  • How do you install a front door?

    First, slide the pins out of the hinges to free the old door. Use the old door as a pattern for where to place hinges on the new door. Create mortises with a sharp wood chisel and install the hinges. Then, put the door in place and replace the pins.
