DIY do it yourself? “FREE ESTIMATES”

There are numerous blogs on the internet that explain how to do DIY expansion joint replacement. We have rarely read one that was accurate. Often, the author misses the details crucial to longevity of the sealant. Preparation is the key which bloggers rarely touch on. We have found that bloggers seem more interested in providing a compelling story to drive website traffic than they are in telling “the entire story”. Bloggers claim it is simple to insert backer rod and apply sealant with a caulking gun without any real experience performing this task. Each project we do is unique and requires its own set of obstacles to overcome. Just bending over or working down on your knees on concrete is hard work, not to mention bloody knuckles from scraping the concrete while trying to remove old sealant or wood.

Grinding or power washing the interior joint wall is critical for sealant longevity. Dust must then be removed from the joint by compressed air and the joint must be completely dry. Backer rod is next to impossible to find at your local hardware store and when you find it, it is generally found to be too small. An average expansion joint ranges from ¾” to 1” in width and 4” deep. Mastic Masters carries 9 different backer rod sizes to accommodate the variety of joint sizes due to movement. This is also why prefabricated expansion joint products don’t work. If they do go in snug, they soon will settle down when the expansion joint contracts.  Prefabricated expansion joints are required by the ACI (American Concrete Institute) to use a lubricant sealant to hold the filler in place and provide 100% water tight seal. See TrimGasket for more details as to the deficiency of pre-fabricated expansion joint fillers.

A consumer can buy a 29oz Tube of Sikaflex SL concrete grey sealant, with no other options in colors, at Home Depot, Lowes or Wal-Mart for about $12.98 a Tube. The package claims you get 12ft at 3/8 bead, meaning you get 3/8 width and 3/8 depth per Tube @ 12ft.  As such, if you had a 1” joint, you would need ½” depth of sealant.
Therefore, you would need 3 Tubes to cover 12 ft of 1×1/2 expansion joint costing you $38.94 plus tax for just 12ft  or  $3.25 a ft. plus tax. This does not even cover the cost of backer rod or any other tools required to complete this project. Mastic Masters charges far less for the same work (taxes included) with a two year warranty and we come to you. We offer 80 color choices to match your concrete. What are you waiting for?

Joint Sealing is a necessity, not a luxury! Joint sealing is specified in every commercial expansion joint in every major city world wide. Your home and property should not be the exception. Sealing joints protect people and property from erosion, staining, trip hazards, pest invasions, splinters and it simply just looks better.
