Dirt, sun, heat, pollution, moisture, cool weather — all affect how the metal on a building looks. Over time, these elements cause metal window frames and metal panels to look faded, aged, stained, pitted, corroded and oxidized.
To properly restore metal surfaces, including anodized or painted metal, HSG usually begins with a light “blocking.” Says HSG Field Estimator Oscar Sanchez, “For proper metal restoration, it’s important to have the right touch — to be careful not to remove any color that’s been applied to the surface, especially along the edges.” This light touch removes 95% of the oxidation and pollutants and exposes the finish’s natural luster beneath. If metal surfaces are extremely damaged, dented or scratched, HSG can provide services to remedy those issues.
Often, the first impression a customer or visitor has of your building is when they enter the parking lot or structure. Businesses that want to make a good impression provide a parking area that is in good, clean condition; free from oil, grease and gum. A Parking Lot Washdown is part of maintaining a safe and attractive facility.
HSG recommends an inspection, where we can walk to determine the following:
Is the floor surface rough or smooth?
Is the parking area indoors or outdoors?
Is there adequate ventilation?
Can the building’s security system be put on “test” while maintenance takes place?
What is the water source?
Is there adequate drainage?
Where will water reclamation barricades be placed?
If the floor has a rough surface, HSG will first sweep to pick up any loose dirt and debris. If the surface is smooth, the sweeper is probably not required. With rough surfaces, HSG frequently uses its commercial “Hurricane” cleaner. This device sprays water, agitates and vacuums up the water and dirt, all in one process. Since the Hurricane vacuums up water, it is also used in areas that are flat and have little or no drainage options.
A dirty building, or the area that surrounds it, is a building that may be visually unappealing. Cleaning a building using a high-pressure technique, and sometimes with cleaning agents, can remove dirt on walls and ledges, frames and mullions. It also gets rid of spider webs and bird droppings. Pressure washing your building can rejuvenate the building and many times prevents repainting.
Most concrete, stucco, or brick buildings should be cleaned at least once a year and parking structure floors once per year. Some buildings, like HSG’s client The Broad Museum’s “veil” are pressure cleaned twice a year. “They want their building to ‘sparkle,’” says Manny Delgado, an HSG field supervisor. Manny has 26 years with HSG.
HSG uses different methods depending on the conditions of the surfaces. Some projects may require only a simple low rinse (with water that includes an additive to help release dirt embedded in pores). Other projects require a hot water application that can include a proprietary chemical mix. This second method may be required if the building has not been washed in a long time. Special cleaning agents are used when white concrete surfaces need to be “whitened.” All chemicals used by HSG are environmentally safe and we comply with all Zero Water Discharge Laws. When the situation calls for it, we can clarify or recycle discharged water. HSG also has a Hazardous Water Disposal Permit issued by the City of Los Angeles.

Southern California property managers and owners have been experiencing a drought for the past six years. During that time, waterproofing may not have seemed so necessary. But when the rains begin or rivers flow, the need becomes obvious.
Leaking roofs, windows frames, joints between concrete panes, and decks on terraces, can become victims of rainfall. Over time, the original vinyl around windows shrinks, gaps form in structures, roofing membranes crack, peel and pull away from edges. Sometimes, the materials used in original construction may be beyond their live span.
Why waterproof your building?
Windows and roofs that leak can lead to mold problems, hazardous to occupants
Water and moisture can damage interior walls
Balconies and terraces are particularly prone to damage as water can sit on flat surfaces for long periods of time
Water that enters an office can not only damage drywall, carpeting and other materials but also tenant property like computers, office furniture, paperwork, etc.
Better tenant relations
Saves money – do repairs before serious damage occurs
When is a good time to waterproof your building?
Before serious damage is done.
Says Karim Lopez, HSG Waterproofing Project Manager, “I had one building owner whose tenant, a bank, rented two floors. Every year, the offices would leak and many documents and some electrical equipment were damaged. At each inspection, I recommended to the owner that she wet-seal the entire building but she held off. Finally, the tenant informed the landlord that they were going to leave. The building, six stories, was finally wet-sealed and the tenant decided to stay. Because the owner delayed the repairs, she ended up spending more money over the four years than if the entire building was remediated in the first place.”
What can property owners and managers do?
When it rains, observe and mark any leaks; leaks may “travel” so an area of up to 15’ around the leak needs to be examined
