At Century Restoration, we take pride in our knowledge of the latest technology and our experience in the industry. We are constantly learning new ways to improve the quality of our work so that we can better serve our customers, to safely and efficiently help to preserve the buildings in which they have invested.
  Metal & Curtain Wall Restoration

When exterior aluminum mullions and panels start to weather, they lose color and luster and buildings look aged and worn.  Oxidation causes pits and crevices to appear and grow.  Metal restoration stops corrosion and renews the appearance of the aluminum.  Since meticulous preparation and application are required to achieve good results, servicing aluminum demands the kind of high-quality workmanship and expertise that Century Restoration, Inc. has built its reputation upon.

Our professionally trained and experience technicians utilize special cleaners and protective coatings to restore the luster to anodized and natural Aluminum.  First, we block the surface to render it smooth and free of oxidation and airborne contaminates.  We then wash it with brighteners to restore the color.  Finally, we apply a sealer to prevent further oxidation and to preserve the restored color & luster.  Regular maintenance is recommended to minimize any future metal restoration requirements.

Building curtain walls typically go for long periods of time before they are cleaned and restored.  Over time they are subjected to many different types of atmospheric pollutants and weather.  Restoring curtain walls is a very time consuming, and labor intensive process.

Curtain walls are constructed out of a variety of materials including: concrete, masonry, stone, natural, anodized & coated aluminum, steel and glass.  The restoration process requires the use of materials and equipment that should only be used by trained professionals.  Aluminum can usually be re-surfaced and sealed, however, we have had to use paint to achieve the desired appearance.  Concrete, masonry and stone surfaces are treated with specialized cleaners to remove stains (nearby metal and glass surfaces are protected), and then the surfaces are high/low pressure cleaned and are ready to be sealed.

Once the restoration is completed, the building can look like new.  Century Restoration, Inc. technicians are ready to perform your curtain wall cleaning, restoration and maintenance projects — call us and schedule a free test.

Caulking & Waterproofing

As original building sealants weather and age, urethane sealants will “revert” (liquefy and ooze out of joints) or become dry and brittle, and vinyl gaskets and seals will shrink and expose air gaps.  Joint sealants are further damaged by movement due to wind loads, thermal cycling and even earthquakes.  Birds have even been known to peck at and eat caulking on parapet cap joints.   As sealants and joints begin to fail, water enters through the cracks and holes, causing up to thousands of dollars in damage.

The amount and severity of damage can increase dramatically if remedial caulking & waterproofing is deferred — minor drywall and ceiling tile damage can lead to concerns about corrosion and degradation of structural steel frames and fasteners, and concrete reinforcing rods (rebar). 

The solution is often to remove the failing sealant, clean, the joint surfaces, prime, if necessary, and finally apply, then tool the new sealant.  Proper joint specifications, training, experience, and good supervision are all needed in order to properly caulk and waterproof.  At Century Restoration, Inc., our project team will ensure that our skilled technicians achieve consistently excellent results.

Once water enters a building through any opening, it can reach structural beams, ductwork and/or ceiling grids, then migrate further inside the building, making it difficult to find leak sources.  Failed parapet cap joints are notorious for causing damage to interior office spaces.  It is not unusual for a client to contact us regarding water damage on a certain floor and upon investigation, we find that the water is entering through a failed joint many floors above the damaged area.  Our ability to find, then properly address leak sources will be a key factor in successfully completing your caulking & waterproofing projects.

Our Project Manager & Field Specialist can help you with inspections, water penetration tests, recommendations, reports & specifications.  We can also bring product manufacturers' experts (GE, Dow Corning, Sika, Vulkem, etc.) to your project to support leak source investigation, identification, and material specification.

We can perform field tests in conjunction with manufacturers' lab tests in order to assist in development of remediation specifications for various joint types, dimensions and materials. Then, we can provide you with a detailed scope of work and cost.  Finally, our experience crews can complete any remedial caulking or waterproofing project according to your budget and schedule.
