Part 1: Simple Door and Window Tasks You Can Do Yourself

With a screwdriver, a utility knife, and a little bit of patience, you can easily conquer these common household nuisances.

How to Fix a Sticking Interior Door: Before you grab a sander or a plane to shave down your door, check the hinges. Most sticking doors are simply sagging from loose hardware.

Open the door and lift up on the handle. If you feel movement at the hinges, the screws are loose.
Tighten the screws on the top hinge using a manual screwdriver (drills can easily strip the wood).
If the screws spin infinitely and won't bite into the wood, remove them.
Dip a few wooden toothpicks in wood glue and tap them into the stripped screw hole. Break off the ends so they are flush with the door frame.
Once the glue dries, drive the screws back in. The toothpicks give the threads new wood to grip, pulling the door back into alignment.

How to Replace Window or Door Weatherstripping: If you can feel a draft or see daylight around the edges of a closed door or window, it is time for new weatherstripping.

Peel off the old, worn-out foam or rubber weatherstripping.
Thoroughly clean the door jamb or window track with rubbing alcohol to remove any old adhesive and dirt. The new adhesive will not stick to a dirty surface.
Measure the length of the frame and cut your new self-adhesive foam or V-seal weatherstripping to size.
Peel back the protective paper a few inches at a time, pressing the weatherstripping firmly into the corner of the jamb or track as you work your way down.

How to Replace a Torn Window Screen: A ripped screen lets bugs in and looks terrible, but replacing the mesh is a highly satisfying DIY project.

Remove the screen frame from the window and lay it flat on a large work surface.
Use a flathead screwdriver or a utility knife to pry up the rubber "spline" (the black cord pressing the mesh into the frame's groove) and pull it completely out. Remove the old mesh.
Lay a piece of new fiberglass screen mesh over the frame, leaving a couple of inches of overhang on all sides.
Starting at one corner, use a spline roller tool to press the new spline (or the old one if it is still flexible) over the mesh and down into the groove.
Pull the mesh taut as you work your way around the frame. Once finished, use a utility knife to carefully trim the excess mesh along the outside edge of the spline.

Part 2: When to Call a Door and Window Expert

While fixing a draft or a sag is a great weekend project, the structural and weatherproofing elements of doors and windows are complex. If you experience any of the following, it is time to contact a professional through the United Handyman Network.

You Have Broken Double-Pane Glass: Modern windows use two panes of glass filled with an insulating gas (like argon) and sealed tightly. If the glass breaks, or if you see condensation between the panes, the seal has failed. This cannot be patched; the glass unit or the entire window must be custom-ordered and professionally replaced.

The Frames or Sills are Rotted: If the wood at the bottom of your window sill or the base of your exterior door frame is soft, spongy, or crumbling, it means water is getting in. Slapping wood filler over structural rot won't stop the leak. A professional needs to find the source of the moisture and rebuild the frame.

You Are Replacing the Entire Unit: Installing a brand new "new construction" window or a pre-hung exterior door requires removing the exterior siding, installing custom drip caps, and applying complex waterproofing tape (flashing). If this isn't done perfectly, water will rot the framing inside your walls.

Your Garage Door Springs are Broken: If your heavy garage door won't open, look at the large coil springs above the door. If one is snapped, do not touch it. Garage door springs hold an immense amount of tension and can cause severe, life-threatening injuries if handled without specialized tools and training. Always hire a pro for garage doors.

The Door is Severely Out of Square: If your door is suddenly scraping the floor heavily, won't latch at all, and you notice diagonal cracks in the drywall above the door frame, your house's foundation may have settled. This requires a structural assessment, not just a hinge adjustment.

The Golden Rule of DIY Door and Window Repair

Never compromise the "envelope" of your home. If a repair involves the exterior siding, custom glass glazing, or the primary lock on your front door, leaving it to a professional ensures your home stays warm, dry, and secure.
