A door closer has one job: close the door and latch it, without slamming. It fails at that job for a few reasons. The closer was undersized for the door, so it cannot overcome wind or stack pressure. The arm was installed in the wrong position for the frame depth. The valves were never set, so the door either slams or drifts. Or the closer leaked its fluid, which happens to cheap closers in cold vestibules. In Toronto, stack pressure in winter is the big one. Warm air rising inside a building pushes outward on lobby doors, and an undersized closer simply cannot latch the door. ## What Is Included in Door Closer Installation? A commercial closer from a commercial door contractor in Toronto [/ →](/) , sized to the door and exposure, with the right arm, mounted properly and adjusted so the door closes and latches every time. ![Technician adjusting door closer sweep and latch speed valves](https://placehold.co/1200x750/12151A/f8fafc?text=Technician+adjusting+door+closer+sweep+and+latch+speed+valves+with+screwdriver+on+ladder) The written CAD spec lists, per door: - Closer model: LCN 4040XP, Dorma 8900, Norton 7500 or concealed overhead - Size and spring power for the door weight and exposure - Arm: regular, parallel, hold-open or stop arm - Mounting: through-bolts, drop plate or reinforcement - Settings: sweep, latch, backcheck and delayed action - All-weather fluid on exterior doors - Rated closer on fire doors Technician confirms specs and price at your free on-site measure. ## Types of Closers We Install ### Surface-mounted closers The most common commercial closer, on steel and aluminum doors. ### Parallel arm closers Mounted on the push side for a cleaner look and better resistance to abuse. ### Hold-open closers For doors that need to stay open during business hours, never on fire doors unless alarm-released. ### Concealed overhead closers Hidden in the head of aluminum entrances for a clean storefront look. ## How Much Does Closer Installation Cost? | Scope | Typical range per door | Main cost drivers | | --- | --- | --- | | Surface closer, regular arm, interior | $450-$650 | Finish | | Heavy-duty parallel arm, exterior | $600-$900 | Size, arm, fluid | | Concealed overhead closer, aluminum entrance | $850-$1,200 | Header work | ## When Should a Closer Be Replaced? - The door slams or will not fully close - The closer is leaking oil - Doors blow open in wind or fail to latch in winter - A fire door does not self-close and latch - An accessibility review flags excessive opening force ## Adjust vs Replace If the closer is sized correctly and not leaking, adjustment may be enough. If it is undersized or leaking, adjusting just delays the next complaint. ## Codes and Standards Rated closers per NFPA 80 on fire doors, opening force considered under AODA on public doors, and closers meeting ANSI/BHMA Grade 1 for commercial use.

Prices are ranges; a technician confirms specs and price at your free on-site measure. How much does door closer installation cost in Toronto? Most commercial closer installs run $450-$1,200 per door. A standard surface closer with a regular arm on a steel interior door sits at the low end. A heavy-duty closer with a parallel or hold-open arm on an exterior aluminum entrance, or a concealed overhead closer, sits at the top. Through-bolting, drop plates and rated closers add to the range. A technician confirms specs and price at your free on-site measure. Why does my commercial door slam or not close? Usually the closer is the wrong size, the valves are out of adjustment, or the closer has leaked its fluid. Wind and stack pressure on Toronto entrances also fight undersized closers in winter. What arm type do I need? A regular arm mounts on the pull side and is the simplest. A parallel arm mounts on the push side and suits doors where the closer should be less visible or less exposed to vandalism. A hold-open arm keeps the door open at a set angle and is not allowed on fire doors unless it releases on alarm. What is backcheck? Backcheck slows the door as it is pushed open near its limit, so wind or a hard push does not slam it into the wall or stop. Which closers do you install? LCN 4040XP, Dorma 8900 and Norton 7500 are common surface closers, with concealed overhead closers on aluminum entrances. Most are sourced within 7 business days. Can you install closers on fire doors? Yes, with rated closers installed within the door label requirements. How long does it take? Typically 3-7 business days from sign-off, and about an hour per door on site. Do closers work on AODA doors? Closers on barrier-free doors must be set for low opening force, or the door should have an operator. See AODA door operator installation. Do you install closers in Newmarket? Yes. An Upper Canada Mall area plaza recently had two Dorma closers installed, sized for the door weight and set for winter wind. Still have a scope question? Our spec desk answers the phone.
