James G Staat Tuckpoointing and Waterproofing


James G. Staat Tuckpointing & Waterproofing Inc. is dedicated to bringing its clients the highest quality work in the fields of tuckpointing, masonry restoration, brick cleaning, joint sealants, water-proofing, stain and graffiti removal.

Joint sealants are your building's first defense in thermal and moisture protection and are found in almost every part of building construction.  From masonry control joints to window frames, from concrete expansion joints to EIFS; each substrate requires special attention when it comes tocaulking these joints.  The choice between using a polyurethane sealant or a silicone could mean the difference between a job well done and a leaky building. 

 Equally important is the shape of the joint and the avoidance of three-way adhesion.  Depending upon the type of substrate and the shape of the joint, different techniques must be applied while installing the sealant to give it the proper profile, insuring it can withstand the compression that results from joint movement.  While reinstalling damaged joint sealants, it is important to completely remove the old caulk to ensure proper adhesion of the new.  But the importance of caulking extends to more than just a defense against the weather. A quality joint sealant project must be seamless and aesthetically pleasing as well. 


  • All of our men are specialized in the process of dry-tooling joints. This process results in better adhesion and increased longevity of the joint sealant
    Close relationships with material manufacturers and a reputation for excellence allows us to be one of few companies able to offer up to a twenty-year warranty on joint sealants
  • Our highly effective inventory system ensures we have the product when you need it and that all our products are kept up to date.
  • Our staff and tradesmen attend training programs given by joint sealant manufacturers to ensure they well versed in all products and all aspects of joint sealants
