Factors Affecting the Cost of Door Addition to a Room
Trim
The trims, also known as casing, give your newly installed door a complete and finished look. It sheaths the gap between the frame and the drywall. Each linear foot of trim installation may cost between $0.50 and $1.50. But if you choose a decorative and custom trim to match the rest of the house, the cost may go higher (somewhere around $5 per linear foot).
Door Framing
The door needs a frame to sit in. If the existing door is in good condition, you don’t have to invest in framing. But if your door is not functional at all and requires major repair, it is better to replace it. Also, if you are opting for a door size that is too big for the frame, the door frame must be changed as well. A new frame can cost you around $250, depending on the size and the area you live in.
Labor Cost
Labour costs will make up approximately 50% of the total cost of interior door installation. The labour cost of removing the old door and installing a new one may cost you around $350. However, if you need additional services, such as wall opening adjustments or custom trims, glass, and accent installation, the cost may rise to $1,500 or more.
Painting the Frame and the Door
Depending on the size of the door, the type of material, and the number of coats used, the cost of painting the frame and the door may be anywhere from $75 to $150. If you want to change the colour of the door, it may cost you more because of the number of coats needed. However, if you want to save some extra dollars, you can consider DIY paint.
Old Door Removal
The old door must be removed when replacing an existing door. Some door installation companies may charge you an additional fee for removing the door, while some include the fee in the cost of replacing the door itself. The cost usually depends on the size of the door and the challenge it poses when removing it. Moreover, removing the door and frame raises the price. Door removal may cost around $20 to $50, and if some installers charge you dumping fees, it may raise the cost.
