Door Maintenance
Keep them rolling and looking good
By Teresa Sedmak
Storage doorsare considered a trademark of the self-storage industry. They are its most recognizablefeature--when people see a series of doors, they normally think storage. That beingthe case, the condition of your self-storage doors makes a huge difference in the overallappeal of your facility. If the doors don't look well cared for, are chalky or dirty, arenot maintained or don't work properly, you may be losing business. As most of us know,customers relate well-maintained, clean properties to safer and more secure facilities.
Maintenance Challenges
Sun, salt air, acid rain and other damaging elements take their toll on the paint onmetal doors and buildings. Ultraviolet rays will eventually fade and chalk even the bestpaint. Salt air can oxidize and pit the metal, causing ugly corrosion. Dirt and dust willsettle and stick on the chalky or oxidized doors. Even when the metal doors or buildingsare cleaned, they can remain dull and dingy.
Dirt or grit in the guides of the doors can gum up the mechanisms. More commercialcustomers are renting storage units and the doors may get more wear. If the doors do nothave bearings, the steel-on-steel friction may cause excessive wear if not maintained.
The original paint on metal buildings and doors, such as aluminum or steel, is baked onin the factory. Many times, when your doors are put up, touch-up paint that matches thecolor of your doors is used by the contractor to cover any scratches. At the time it istouched up it matches very well, but the non-baked paint will oxidize more easily, andblotches can appear where the touch-up paint fades faster than the original.
While roll-up doors generally require little or low maintenance, there are someperiodic preservation procedures you can use to ensure better-looking, longer-lasting andwell-working doors and buildings.
Maintenance Solutions
Fading and Chalking
Doormanufacturers are constantly working to offer better paint finishes. Even though metaldoors and buildings will eventually fade and chalk from sun exposure, the good news isthere is still good paint under the chalk that can be refinished to look new. But if youclean the doors or metal buildings and don't seal or protect the surface, they will soonfade or chalk again.
Some owners repaint their metal doors or buildings to brighten them up. There are,however, problems with repainting the metal. Moisture can get inbetween the originalbaked-on paint and the new, softer layer of paint, causing bubbling and peeling. Paintthat is not baked on will also oxidize much faster than original paint, bringing back thechalking and fading problem the owner attempted to solve in the first place.
Instead ofpainting to brighten up faded metal doors and buildings, refinishing with a high-quality,protective coating is a good alternative. Once the surface is cleaned from chalk and othersoiling agents, a good clearcoat can restore the doors' former appearance. Make sure thecoating will bring back the original color, be easy to work with, will not crack, peel ordiscolor with exposure to the elements, and will protect from sun, salt air, acid rain,moisture and other damaging elements. A good protective coating will also make the doorsmuch easier to keep clean by repelling dust and dirt.
If your metal doors and buildings are already peeling, or if you need a color change,repainting is the only option. Make sure you have the surface properly prepared, and usequality materials. If you are planning to slurry coat your property, have the refinishingor painting done first. In either case, the chalky oxidation will have to be removed andcan cause stains if not washed off the slurry immediately.
Salt-Air Oxidation
In areasclose to the ocean or even by Salt Lake City, pay particular attention to the tops ofdoors, especially on the sides of the building that don't dry as quickly because of lackof sun exposure, such as the north side. Even if you are miles from salt water, you canget oxidation from the fog. Rub your hand along the doors. If they are rough, that issalt-air oxidation, and it can cause extreme corrosion and damage to your doors andbuildings.
Similarly, if you use salt for snow and ice control, keep an eye out at the bottom ofyour doors and metal buildings for corrosion. This corrosion needs to be stopped before itcauses major damage. Paint alone cannot stop rust or corrosion. Paint breathes and willallow moisture to penetrate, and rust can travel underneath or quickly penetrate backthrough. In areas where salt air is a problem, check your interior doors for corrosion aswell, especially if your hallways are open. The moist salt air can settle and corrode theinterior doors as well. A protective coating formulated to stop salt oxidation willprevent additional damage.
Door Numbers
Door numbers will eventually fade and crack, creating a poor impression forpotential tenants. When replacing numbers, use the highest-quality vinyl numbers possiblein an easy-to-read, block style. Otherwise, you will be replacing your numbers more often.
Periodic Maintenance
When aunit is vacated, there are several procedures to ensure your doors remain in good workingorder:
When you sweep out the unit, sweep any cobwebs and dirt out of the guides on the door. You may want to wipe them down with a rag to remove dirt that will interfere with the smooth operations of the door. Do not use grease or WD-40 on the guides as it will attract dirt and grime and gum up the rollers.
Check to make sure the door is securely screwed into the wall. The screws may have backed out after excessive use. Sometimes none of the screws are in place.
Oil or lubricate the springs with a very light coat of oil to reduce friction and prevent rust. Check the tension and adjust according to the manufacturer's directions. Maintaining the spring tension and making sure they are balanced is critical. People who hurt their backs trying to raise doors that stick or open unevenly can file lawsuits.
Check the pull cords, especially if they are on the outside, as they wear very quickly. Frayed cords do not give a well-maintained image. Tom Berlin, vice president of operations for Pogoda Management Co. in Michigan, says nylon rope is very durable when used for pull cords, particularly in colder areas where routine winter maintenance (i.e., snowblowing) can damage them. Make sure you melt or singe the cord ends so they won't fray.
Inspect the unit for signs of leakage, and replace worn weather seals as necessary.
If your doors are dented, Roll Right Industries of Anaheim, Calif., offers dent tool kits that fit the doors of several manufacturers. Terry Rider, the company's national sales manager, also advises that if you must paint older doors, make sure to readjust the springs to compensate for the extra weight of the paint.
In conclusion, since the appearance and smooth operations of your doors project yourimage to the public, maintenance does not cost you money. It makes you money and keepsyour customers and employees happy.
