Masonry Cleaning and Sealing in East Syracuse

Three municipalities in this metro authorized no new single-family housing units at all in 2022, 2023 or 2024: Camillus village, East Syracuse village and North Syracuse village. Liverpool village authorized one over the three years, and Baldwinsville village and Fayetteville village two each. Read alongside the housing age data, East Syracuse village and Solvay village both report 0.0 percent of their housing built in 2000 or later.

Ranked by the share of housing units built in 2000 or later, the era in which adhered stone veneer and segmental paver hardscape became the dominant new masonry products, the places of this metro spread very widely. Radisson, the census place inside the Town of Clay, leads at 32.4 percent, followed by the Town of Lysander at 25.8 percent, the Town of Van Buren at 21.9 percent, Baldwinsville village at 20.1 percent, the Town of Cicero at 19.1 percent, the Town of Clay at 15.4 percent, the Town of Camillus at 15.2 percent, the Town of Manlius at 11.6 percent, the Town of Marcellus at 11.3 percent, the Town of Skaneateles at 11.2 percent, Marcellus village at 9.9 percent, the Town of DeWitt at 8.7 percent, Skaneateles village at 8.4 percent, Fayetteville village at 8.1 percent, the Town of Salina at 7.0 percent, the City of Syracuse at 6.4 percent, Camillus village at 6.4 percent, Liverpool village at 6.1 percent, North Syracuse village at 4.7 percent, Manlius village at 4.5 percent, and both East Syracuse village and Solvay village at 0.0 percent. The county figure is 11.6 percent.

The county hazard mitigation plan describes the Bear Trap and Ley Creek Drainage District, which runs through North Syracuse, East Syracuse and the built-up ground between them, as flat and heavily urbanized, making the lowest areas extremely vulnerable to flood events that approach or exceed the five year storm, and states that this occurs about three times a year. The Village of East Syracuse annex records that it has no jurisdiction or oversight over the district, and its own action to study the most at-risk properties was discontinued for that reason.

National Flood Insurance Program figures in the county hazard mitigation plan annexes show how differently water behaves across the northern towns. The Town of Cicero has 180 active policies and 153 claims paid totalling about 1.44 million dollars. The Town of Clay has 93 policies and 49 claims paid totalling 455,606 dollars, and no repetitive loss or severe repetitive loss properties. North Syracuse village has 4 policies and has had no claims paid at all, a total of zero dollars. Solvay village has 3 policies and 6 claims paid totalling 10,957 dollars, and East Syracuse village has 9 policies and 12 claims paid totalling 223,722 dollars.

Efflorescence needs three things at once. Technical Note 23A states that soluble salts must be present within or in contact with the masonry, that a source of water must be in contact with the salts long enough to dissolve them, and that a pore structure must be present that allows the salt solution to migrate to a surface where the water can evaporate, driven by a temperature or humidity gradient. It adds that the assumption that the brick causes efflorescence is usually incorrect, because the soluble compounds most commonly originate in the materials in contact with the brick, such as mortar, grout, concrete masonry, concrete or soil.

The hardscape equivalent of the same problem has a named failure mode. The sealing guidance lists the conditions under which a sealer or liquid stabilizer will whiten on a paver surface: the surface and joints are not dry, the pavers have not had an adequate period of exposure to moisture, there is a source of efflorescence under the pavers in the sand, base or soil moving up through the joint sand or the pavers, or the sealer is not breathable, meaning it does not allow moisture to move through to the surface of the paver and evaporate. It adds that if the base under the pavers drains poorly, the sealer is applied to saturated joint sand, or it is applied too thick, the sealer can become cloudy and diminish the appearance of the pavers, and in that situation the sealer must be removed or re-dissolved.

Sealing is a recurring appearance choice, not a one-time structural upgrade. The guidance states that sealers are applied to add further protection from stains, oils, dirt or water, that most sealers change the appearance of the paver surface by darkening it and enhancing the surface color, and that sealers normally require reapplication after a period of wear and weather, with the interval depending on use, climate and the quality of the sealer. It separately notes that joint sand stabilizers and sealers are two distinct products with overlapping functions, the stabilizer's primary job being to keep joint sand in place against flowing water, wind, aggressive cleaning, tire action and the intrusion of organic matter, seeds and insects.

A sealer can make the problem worse in a specific, documented way. Technical Note 23A states that applying a coating to brickwork that has a tendency to effloresce, without stopping the mechanisms causing that efflorescence, may lead to degradation of the masonry, and that applying a coating that inhibits evaporation may also lead to degradation. As water and dissolved salts travel toward a coated surface they may be stopped at the inner margin of the coating, usually 1/8 to 1/4 inch below the surface, where the water evaporates through the treated zone as vapor and the salts crystallize inside the masonry. That is called cryptoflorescence or subflorescence, and the Technical Note states these salts can develop tremendous pressures which may result in brick spalling. For that reason, coatings are not recommended as the sole treatment for efflorescence problems.

Masonry should not be cleaned during freezing weather or when freezing weather is expected, because most cleaning methods saturate the wall with water and that water can freeze on or inside the masonry and damage it. Technical Note 1 recommends that water-based cleaning methods be used only if the ambient temperature will be 40 degrees Fahrenheit or above and will remain so until the brickwork is dry.
