The removal consists of unhanging the old door, removing old hardware and if the old frame is filled with concrete or mortar, then a hammer drill will be used to break the frame away from the wall.


Installation consists of cleaning the debris from the removal process, and installing the frame to be level, plumb, and square. Then using a hammer drill, we drill holes in behind the frame, and use structural anchors to secure the new frame to the building. All exterior frames will be insulated for frost protection.

      PRODUCTS &                     HARDWARE.

Domar Doors uses only the highest quality products and hardware in the industry. We proudly provide all of our hardware with a one year warranty on manufacturer  defects. All of our material for installation are top of the line materials. Such as the caulking, insulation, spray foam anchors, wood backing and bracing, as well as the highest quality steel products for your door and frame.


- How much does a door installation cost?

There are door options for every budget and timeline. Typically, replacing an existing, standard commercial man door costs between $500 AND $8,000 including materials and labour.


Yes, that's a HUGE range, but each job is unique. Some of the things that increase the cost of the job are:

  • type of door,

  • type of frame,

  • thickness of steel for both door and frame

  • the type of core in the door( polystyrene, polyurethane or honeycomb core)

  • the hardware that is chosen


Another cost factor is the labor it takes to remove the old door and frame. Costs increase if the old frame is embedded in concrete, as we will have to "chip" the frame with a rotary hammer drill to separate the old frame away from the concrete structure.


Another added cost can result once the frame has been removed and there is a hollow cavity behind the frame on the structure, as we will have to "build up" the cavity with material to anchor the new frame.


- What are the differences between the different types of commercial doors?

The standard commercial door is non-fire rated 20ga steel thickness with honeycomb core.


A popular upgrade is to a polystyrene fire rated 16ga or 18ga door, which can  resist fires from 20 minutes up to 3 hours and the thicker steel will withstand harsh traffic such as carts, garbage bins, containers of all sizes and much more.


There are also Dutch doors, storage doors, exit doors stairwell doors, and security doors. That all have different benefits and challenges depending on the application. 


- What door should I get if I want to reduce my energy costs?

For commercial establishments with normal foot traffic, we recommend a polystyrene or a polyurethane door, for all exterior doors with weather strip and thresholds and brush-sweeps as it provides an insulation value of roughly R-6.5 for polystyrene and roughly R-11 for polyurethane, which can save you hundreds of dollars per year on your utility bill.


There are many other building envelope factors to consider, but a polystyrene and polyurethane door is one way to reduce energy consumption. 


- How long does it take to do the job?

Typically, the day of the job, replacing an existing, standard commercial man door takes 8 to 12 hours and can be done either during business hours, or after hours.


Some of the things that increase the installation time are:


  • the frame being embedded in concrete, in this case we use a rotary hammer drill to separate the frame from the structure.

  • if the opening is no longer square from the building settling and shifting we may have to make modifications of the frame onsite to account for the opening to fit the frame so it is level, plumb, and square

  • more time consuming issues are the building structure itself, if there is a air cavity between the exterior walls and interior walls then we will need to "build up" the cavity to anchor material so the frame can be secured to the building.

- What parts of the region do you service?

Anywhere in the 613 or 343 area code, though a fuel surcharge may apply outside the city of Ottawa.


At this time we are unable to service clients located in Quebec, but we're working on it, and can recommend other quality firms!


- What do I have to do to prepare?

We'll cover that during the initial consultation, but in general, please ensure that 8 feet around the door is free of debris and clutter, any employees or customers are kept away from the construction area, and that there is space adjacent to the door opening to keep materials and supplies. stored as the work ensues. 


- Can I supply my own materials?

There is no definitive answer and it varies on a case by case basis and can be discussed during the consultation.


We stand behind our work, so we insist on using new hardware and doors rather than reusing components, as the manufacturer provides a warranty and we're assured the products are straight, true, and free from defects. 


- Is there a break in period, or anything I should be aware of after installation?

Most doors are ready to be used immediately after installation. All care and maintenance instructions will be shared with the owner.


Some installations, such as poured grout for the threshold (door sill), may require 24 hours until they are serviceable, giving the components time to adjust. 


- Can I modify my existing doorway to make it taller or wider?

Typically we want to keep the same size of the opening to keep the integrity of the building and opening.


Any and all modifications of the opening will need to be made through another contractor and Domar must be informed of opening modifications for ordering purposes.


Generally, door openings CAN be widened or lengthened, but it depends entirely on the architecture of the building, and may need engineer approval to modify. 


- Can I close up an existing doorway and relocate the opening to a new location?

You can close an opening but you may need engineer approval and Fire Marshall approval as well, as most exit doors are fire rated .


Closing up an existing doorway is fairly straightforward. Creating a new door opening has numerous variables that need to be considered, such as: engineering specs size of opening material to build up or widen the opening, and most importantly, getting permits for certain projects such as load bearing walls.
