When you are fastening two pieces of wood with screws, keep the pilot hole through the top piece slightly larger than the diameter of the shank of the screw. This will allow the wood screw to pull the two pieces of material tightly together. If the pilot hole is too small, the top piece can climb the threads of the screw and leave a gap between the two pieces.
Spring is the perfect time to inspect door and window screens for tears. You can often repair small tears using a kit from your local hardware store. This will prevent insects from getting into your home, and keep you comfortable on the screened porch.
