This week as I drove through Chicago, parts of the North Shore, Oak Park & River Forest, I was amazed at how much low-quality restoration work was being performed by folks passing themselves off as "masons." In most cities and suburbs in Cook and Lake Counties, individuals do not need to be licensed in the sense that they have been certified as "competent" or "expert" in the trade. Often, these people need only submit proof of insurance and pay a modest fee for a business license to be able to claim they are qualified to perform what is, in effect, surgery on your brick home or building. That's unsettling.
Recently I drove by a service vehicle which caught my eye (see below). A few things I have learned about this industry in my 20 years running the family business and this photo seemed to capture them.
1. A fancy truck does not a restorationist make. Lots of new trucks are purchased by folks looking to make a nice first impression. Many of these trucks are re-possessed a year later because the skill set of the mason driving the car falls far short of expectations.
2. If the tradesman cannot spell his trade properly (or does not catch the misspelling of his trade on the side of his fancy new truck), then he's probably going to miss some details on your project...or worse.
3. Tradesman should focus on one trade only. We've seen concrete driveway repairmen pass themselves off as masonry restorationists. We've seen roofers try to pass themselves off as masonry restorationists. Heck, we've even seen painters try to pass themselves off as masonry restorationists — what does a paintbrush have in common with a trowel? Tradesmen should focus on one trade and one trade only. For 60 years we've been focused solely on masonry restoration work (grinding & tuckpointing mortar joints, restoring bricks and lintels, washing, caulking and sealing masonry). Every one of the foremen at this company has been in the field performing masonry restoration work (and only masonry restoration work) for 28 years or longer. We do not roof, we do not pour concrete driveways, and we sure do not paint homes.
If you have a masonry issue, we would like to help.

On almost a daily basis, AAA-1 Masonry & Tuckpointing receives calls from owners of newly constructed homes and buildings (i.e., structures built with concrete block or split-face block walls within the last 15 years) complaining of water leaks.
Because concrete blocks are mostly hollow and are so much more porous than bricks found in older structures, wind-driven rain usually blows right through the block walls and into the wall cavity. To limit the damage due to water infiltration through block walls, waterproof membranes are usually installed at each floor in a multi-story building and at the top of the parapet wall. Unfortunately, improperly installed flashings are very, very common in new construction dwellings and fail to stop water infiltration. That's why we see water marks on ceilings, and around balcony doors and windows in so many newer homes and apartments. Water infiltrations through concrete block walls short out electrical wiring, and burn out light switches and outlets, and are a real fire hazard. At a project in West Town (see photos), we pulled back a parapet wall's improperly installed flashing to discover water all over the underside of the material it was designed to repel. No wonder the block's hollow cells were soaked and the paint on the owners' bedroom walls were peeling!
Only when concrete block cells are grout-filled solid, and drip edges and membranes are sized properly and installed correctly can one be assured of a water-resistant flashing detail. All of AAA-1 Masonry's licensed masons know this. That's why after hundreds of parapet wall flashing installations we can boast a 99% success rate stopping water infiltration.

These are birds-eye photos of a client's concrete block parapet walls after we removed the metal capping. Last we checked, empty cigarette packages, Coke bottles, and cardboard were not approved by the Department of Buildings as wall-reinforcing materials. They also do little to keep wall cavities dry. We grout-filled all of the accessible hollow concrete block cells, and installed through-wall flashing and stainless steel drip edges before installing properly sized quarried limestone capstones with cut drip edges.

Flashing or Through-Wall Flashing is a waterproof membrane used to stop moisture from penetrating porous masonry or to re-direct water out of a masonry wall. High quality flashings are composed of copper, lead-coated asphalt or other durable materials which do not degrade from long-term exposure to moisture or ultraviolet rays. When installed properly, flashings should extend the full width of the wall (or beyond) and are often paired with stainless steel drip edges.
AAA-1 Masonry & Tuckpointing was called out to a Lincoln Park residence to determine how water was infiltrating the dwelling. After removing the parapet wall capstones we discovered that the builder had used an inexpensive plastic membrane—the black material laid across the top of the wall—and had failed to size it correctly (refer to photo at left). Membranes must extend the full width of the wall in order to function properly, and here the flashings stopped a good two inches inside the walls rendering it completely ineffective. After disposing of the inappropriate flashing and allowing the wall cavity to dry out, we installed the correct flashing detail and re-set the capstones.
In this photo, AAA-1 Masonry & Tuckpointing is in the process of replacing a severely deflected third-story window lintel in a loft building in downtown Chicago. To the horizontal leg of the new window lintel we secured stainless steel drip edges in a continuous bed of caulk, and installed self-adhering Grace "Perm-A-Barrier" through-wall flashing and fastened it to the brick back-up wall using termination bars, masonry screws and caulk. On the right end of the masonry opening, we are in the process of installing a field-constructed end dam designed to prevent water from migrating into the masonry jamb. (Note how the glass window has been protected with Visqueen and painter's tape.)

AAA-1 Masonry & Tuckpointing performed a gut-rehab of an industrial office space in the Edison Park neighborhood of Chicago.
Extensive demolition work was performed over the winter including removal of the drop-ceiling tiles, the damaged carpets, the drywall and most of the plumbing. (In fact, just about everything but the door to the 60-year-old safe was in terrible condition and unable to be salvaged.)
After demolition work, it was decided that the exposed steel beams, wood roof rafters and Chicago common brick walls lent themselves to a terrific century-old industrial look. After creating larger openings for new windows and building new masonry walls for conference rooms and work space (and, yes, the original safe), everything was sandblasted to give it a rich glow.
