Do you need to buy hardware?
Prices for door hardware starts off at less than $50 for a simple, low-end knob set but can run up to several hundred dollars -- especially if you want a high quality lockset. You'll also want to make sure you're buying the right hardware for an exterior door, since not all interior door knobs come with locks, and may not be as sturdy as you'd like for the entrance to your home.
There's also a chance your door already comes with the hardware you need to fully install it. Make sure you know what the door comes with before you buy it, so the installer can quote you an accurate estimate of materials and labor for the job.
Will you replace an existing door?
Installation cost is also affected by whether the door is part of new construction or is a replacement as part or a home remodel. With new construction, it'll likely be wrapped up in the total cost. If you want to replace an old door, you may be able to repurpose existing parts, like hinges and frame, therefore bringing down the overall cost.
Regardless, you'll have to pay attention to building regulations. Be aware of any building code requirements or historic preservation rules that may limit your choices when picking out a new door. Even if you had your eye on that cheaper steel door, regulations may require you to purchase a wood one to fit in stylistically with the neighborhood or building.
Other codes might require you to get a fire rated door. This type of door also adds to your overall cost.
Is it a sliding door?
Sliding doors and bi-fold doors are a little more complicated to install and will cost more. For sliding doors, your cost will go up if you have more than two panels.
Is your door and frame standard or custom dimensions?
The standard and popular door sizes are widths of 30, 32, and 36 inches with a height of 80 inches. The standard thickness is 1 3/4 of an inch. If the measurements of your existing door or opening do not match these numbers, your door and frame may be a custom size. This will raise costs.
Installing a custom door will raise the cost of your replacement door, since it could be difficult to find the right size or you may need to have one custom made. It can also increase labor costs, since it might be more complex and time-consuming for your contractor to install.
What's included in an exterior door installation cost?
A contractor should quote you for both the material and labor costs for your door replacement. If you want your contractor to purchase a door for you, they can include the price of the door and hardware (hinges and knobs) in their total cost. The total cost will also include the labor cost to:
Most contractors who do door installation are also locksmiths. Installing or replacing your door involves several steps, all of which are included in the overall rate.
How can I save money on the cost of an exterior door installation?
The most inexpensive way to replace an exterior door is to use the existing frame and buy a replacement door that fits it. Ideally the existing hardware is in good repair and can also be used.
For instance, Second Wind Consulting & Contracting, a contracting firm in La Jolla, California, charges about $300 in labor to replace a door and use the existing door frame. They charge about $400 in labor to change both the door and its frame. What should you ask before hiring a contractor?
Before you hire someone to install your door, ask the following questions:
Can I have a free estimate?Ask for an estimate before commissioning any work. Be prepared to tell the prospective contractor what the new door will be made from, what kind of building the door is being attached to, and whether you prefer pre-hung, slab, or if you would like to use the existing frame. The builder may also want to know the size of the door and the entryway to the house to provide the most accurate estimate.
What are your previous experiences with installing doors?When trying to find somebody to help you with a door replacement, keep in mind that tasks like window and door replacements are not considered a specialty skill like plumbing or electrical work. The labor to replace a door requires the installer to have the basic carpentry skills of sawing, measuring, drilling and securing fasteners.
At the same time, a door must be centered, shimmed and correctly suspended in its frame or you will have problems with opening, closing and locking the door. A search for door contractors should take you to general contractors, carpenters, and handymen.
