With the advent of wireless technology, computer users can install cables throughout a building. However, there are cases where cables are required. You can call a professional to route the cable from room to room, but this is often expensive. This article will use some of the techniques and tools you need to get a general idea of how to run cable from basement to second floor.

How to Run Cable from Basement to Second Floor

How to Run Cable from Basement to Second Floor

Certain phases are involved in cable running from the basement to the second floor. Whatever the floor, the processes remain the same. They are explained below.

Step 1: Check the building code

According to the safety standards of some regions, any cable can be dangerous. Although it allows you to install low-voltage cables, such as speaker cables, telephone lines, and network cables, check the building codes for certain cables.

Step 2: Assemble the instruments and perform the measurement

You will need a few tools to run the cable from the basement to the second floor. They contain a 3/4″ drill, cable holder, cables, measuring tape, cordless drill, hammer, etc.

Choose the right cables with higher fire resistance to suit your walls. Next, measure the distance to the devices on which the cables will be used. The cable will have to be laid between the floors and along the skirting boards and walls.

Therefore, you will also need to consider these calculations. It is best to use a longer cable than necessary. Later, this will provide more room for adaptation.

Step 3: Identify the access point and turn off all power supplies.

Find the access point in the middle of the second floor. The cable will lead from the upper floor to the basement. It is best to choose a location near the wall in the basement.

Locations for wiring should be avoided. Then disconnect all power supplies to prevent damage to living wires.

Step 4: drilling

Take a cordless drill because your home is without power. Insert 3/4 bit into the drill and start drilling, holding the machine at a 90 ° angle to the floor. After drilling the base and the floorboard, remove the drill.

Replace the 3/4-inch drill with a 12-16-inch extension. Then insert the 3/4-inch drill bit into the drill bit. Start drilling again in the same hole, keeping the same drilling angle. Stop drilling as the drill passes through the ceiling of the lower room.

Step 5: installation

The next step is to install the cables. Start at the highest levels and use cable ties. Then guide the wires along the skirting boards. The cable holder holds the cable in place with a clamp.

In addition, the built-in nail fixes the fastening itself to the surface of the skirting board. Place the binding every four feet. Now insert the cablesinto the holders and insert them into the wall. You must continue until you reach the opening of each floor.

Step 6: Complete the connection.

Then pass the riser through the hole. Next, extend the hanger and glue the cable along the length of the hinge. Then you have to thread the cable and the curtain through the hole in the first and second-floor ceiling.

Continue to pull the cable out of the hole and lower to the lower level. You don’t have to deal with tangling problems when running cables along walls. Connect the cables to the basement walls.

As before, use cables to secure cables to walls and skirting boards. Place the links 4 feet apart. Now connect the cable to the predefined devices and then turn on the power. 

How to Run Basement to the Top Level with an Ethernet Cable

  • Measure the distance between the Ethernet cable-connected devices. An Ethernet cable connects one device to another, such as a computer. The Ethernet connection goes between floors and along the walls and plinths. 
  • Measure the length of any walls and skirting boards where the cable will be exposed. To accommodate for inaccuracies in the overall measurement, add extra 10 feet to the entire measurement.
  • Locate the floor-to-floor access point. The cable runs from the second story to the basement, passing via the location on the lower level closest to the gadget. Locate a location in the upper room’s corner or near the upper room’s motherboard. 
  • Choose a spot that is as near to the basement wall as possible. Ideally, this location should be directly above the installation site in the basement. Avoid places with wirings, such as ceiling lights or light switches. If the drill comes into contact with live wires, disconnect all power to avoid problems.
  • Drill the floor with a drill. Keep the drill at a 90-degree angle with the floor. Pull the drill out of the hole and remove it after drilling the floor and the substrate. 
  • Reattach the drill bit 34″ to the end of the extension to connect the 12-16 “bit to it. Using the bit, drill into the hole. Drill the lower ceiling while holding the drill at a 90-degree angle. When the drill pierces the bottom room’s ceiling, it comes to a halt.


  • Make sure the Ethernet cable is connected to the PC. Starting at the topmost level, use cable ties to route the cable down the skirting boards.
  • The cable holders contain a clip that clamps the cable and a built-in nail that secures the holder to the skirting board’s surface. Then, every 4 feet, place the binding. 
  • Connect the Ethernet cable to the wall by inserting it into the holder. Continue walking until you reach the gap in the floors.
  • Insert the cable into the hole. Fold the wire hinge in half. Wrap the Ethernet cable with tape along the hinge’s length. 
  • Take the cable down to the lower level and feed it through the hole.
  • Run the cable through the basement walls and secure it. Use cable ties to connect the cable to the system board along the wall. 
  • The brackets should be spaced 4 feet apart. The project is complete once the Ethernet wire is connected to the devices.

Frequently Asked Questions

How to lay the cable from one floor to another?

Drill a hole in the floor. Pass the wire through the hole. Next, route the wire through the back of the junction box, insert the box into the wall and reinstall it.

Is it possible to lay an electrical wire under the house?

The building authority may want to check the electrical panel to ensure it is large enough to handle the new circuits. If you do not have an electricity license, you may not connect the wires, but you can run the cable under the floor and hire an electrician to make the connection.

How to lay an Ethernet cable in a finished household?

You can use the inside of the toilet as a wire pen. Pull the cable to the cabinet that corresponds to the wall. If you want to install closet doors, measure the distance between doorways on either side of your cabinet and draw lines along these dimensions. On the second floor or in any other area where there are no windows that may be visible from outside this building, then mark out an 8ft x 4 ft. square using tarps/tarp stains (whatever is available) as borders around each room’s designated space.” The door is cut on the inner wall, so you can’t see the wire even if you look in the cabinet.

How do I run a coaxial cable through walls?

Coaxial cables are connected from the center near the TV signal source, be it a cable TV or satellite dish, to any room where the TV’s internal connections must be available. This configuration forms a star topology. The multiport distributor is located in the center of the star.

How to run a cable from one room to another?

Insert the coaxial cable from the manifold location into each additional room. To reduce signal loss, use the shortest cable possible in each room and avoid severe curves and bends. Drill the holes on the floor, walls, and ceiling with a drill.

How do I lay an Ethernet cable in a two-story house?

Use a 3/4-inch bit to drill through the substrate and make sure the drill bit is perpendicular to the floor. Next, remove the drill bit and then use the 16″ drill bit extension to drill the entire ceiling. Finally, route the Ethernet cable through the hole.


The routing of cables from the basement to the floors above requires systematic steps. Procedures are risky and should involve an experienced electrician or someone with a basic knowledge of them. This means that inexperienced homeowners should never decide for themselves. Hope you have learned how to run cable from basement to second floor.
