Moreland Courts Condominiums

It’s upscale as it is historic.

Moreland Courts luxury condominiums feature swanky amenities like complimentary valet parking, and conference-calling capability in every suite.

Cleveland architect Alfred W. Harris designed the luxury building apartment complex in 1922 with the stated intention of writing “the entire history of English architecture” on the exterior. The result was a campus of 13 six-to-eight-story masonry buildings lavishly decorated with details from the late Gothic and Tudor to the Jacobean and Georgian.*

As the decades passed, many of Cleveland’s leading citizens made their homes in the 147 six-to-nine-room apartments at Moreland Courts. The complex went condo in 1979.

Though always a desirable address, age and deferred maintenance took a toll on the elegant complex. In 2005, after years of planning, the Moreland Courts Condo Association undertook a $12 million effort to restore and update the building for the 21st century.

M-A Building & Maintenance Company, Cleveland, got the job of cleaning and repairing the red brick, sandstone and limestone exterior. It would be the building’s first cleaning since Moreland Courts opened its doors in 1929.

“There was a lot of black,” commented Pete Wamelink, M-A Building & Maintenance Company’s president and project manager. Moreland Courts lived through the heyday of Cleveland’s steel mills, he explained. It had the carbon stains to prove it.

Knocking it off took one of the most powerful products in PROSOCO’s arsenal – Sure Klean® Heavy Duty Restoration Cleaner NE. The “NE” stands for Northeast.

PROSOCO created this cleaner specifically to break the grip of the heaviest atmospheric soiling the big Northeastern industrial cities offered.

The M-A Building & Maintenance Company crews went after the soiling two buildings at a time starting in March 2005.

Their procedure began by thoroughly wetting down 20 by 20 square-foot areas of masonry. This “pre-wetting” keeps the cleaner on the surface, where it attacks the contaminants.

Next, the crews hit the dark, wetted film with Heavy Duty Restoration Cleaner NE from airless sprayers.

They let the cleaner chew up the contaminants 5 -10 minutes, based on severity of stains and tests conducted before the cleaning began, Mr. Wamelink said.

Then the crews pressure-washed away the spent cleaner and solubulized soiling, leaving – in most areas – pristine brick. Some parts of the wall were so profoundly stained that it took up to three applications of the powerful cleaner.

Behind the cleaners came the tuckpointers. Beneath the soiling, bricks had weathered and many mortar joints had failed, letting water into the walls. By project’s end the M-A crews had tuckpointed 100,000 square feet of masonry, and replaced 90,000 bricks.

The onset of wintry weather in November brought the exterior work to a temporary halt with six buildings cleaned and repaired. The crews returned in March 2006 and started again.

Though the brick soiling was tough to remove, stains on Moreland Courts’ limestone and sandstone trim, sills, quoins, entryways and other natural stone details was even more entrenched.

Since the limestone was too sensitive for the aggressive Heavy Duty Restoration Cleaner NE, Mr. Wamelink turned to Sure Klean® 766 Limestone & Masonry Prewash, followed by Sure Klean® Limestone & Masonry Afterwash.

Applications of the alkaline 766 debonded most of the stains built up on the stone surface. Follow-up cleaning with mildly acidic Limestone & Masonry Afterwash neutralized any lingering alkalinity, and added a further cleaning/brightening effect. Though about 10 percent of the staining had penetrated deeply over the decades and couldn’t be reached, the difference in the stone, was, Mr. Wamelink said, “night and day.”

Overall, the difference added up to gold – the company’s work on Moreland Courts garnered an International Masonry Institute 2006 Golden Trowel Award, as well as awards from the Builders Exchange of Cleveland and The Cleveland Restoration Society.
