We are experts at leak detection and repairs

One of the most common problems with a large number of buildings is water leaks. Where seals degrade over time, it is worth having them professionally checked periodically. If leaks are not recognised and resolved within a timely matter, the leak can spread beyond the window, consequently meaning the structure of the building may become compromised.

As professionals, we are here to identify the exact nature of the problem. Over the years, we have re-sealed windows on a large number of residential and commercial buildings in Sydney, Wollongong and Newcastle.

Our procedure

  • Cut out faulty old seal
  • Clean the area to be sealed with appropriate surface cleaner or methylated spirits
  • Apply primer
  • Apply polyurethane sealant and smooth with spatula
