Clear Choice Window Cleaning would like to say that it has been a joy to work with property management companies in North San Diego County. During this rainy spell we have been sealing leaking windows on the buildings we maintain with clear silicon. This is a painstaking task that involves running a bead of waterproofing caulk around the window to make it watertight. I have found a few common reasons why windows leak around the edges: wood-frames have a tendency to breakdown in the moist sea-air and they are prone to termite activity, also the sun breaks down the rubber stripping that seals glass in metal-framed windows; large pains of glass often get so hot in the summer that the rubber encasement warps. Re-Sealing windows involves applying a bead of clear silicon around all four edges and is a specialized task inherent in the upkeep of old commercial buildings. Of course we are always glad to re-seal a leaking residential window too. When caulking a window-frame it is important to be neat and precise. There is a measure of skill involved in doing the job right. Experience is important as well as having the right equipment and skill to access windows that are high above the ground. Based in Carlsbad, Clear Choice is a company that specializes in accessing hard to reach places. In addition to window cleaning it is our pleasure to seal windows, along with power washing and screen repair.
