The total solution for window and door waterproofing and installation

Industry Problems

  • Human Error

    Let’s face it, window & door openings are rarely square. This causes issues with the window installation process and makes it difficult to meet proper installation requirements put fourth by the manufacturer and/or local building codes.

  • Material Expense & Waste

    Are you tired of constantly seeing unusable trim and lumber accumulating after each install? It’s frustrating to have to pay for material that you don’t use and pay a fee just to trash it in a dumpster. Imagine a fresh install with no material waste to have to deal with.

  • Schedule Restraints

    We know the difficulties of having to set aside progress on one part of a project in order to give priority to another part. Unfortunately, not everything can be done simultaneously, unless you’re using Deco-Flash.

  • High Labor Costs

    Window & Door installations can be tedious in many ways. It’s not an easy job to unload heavy units and carry them to their corresponding rough openings, and it usually takes many laborers. When it comes time to actually dry fit the units, you’re never guaranteed a perfect fit. It usually takes several attempts and adjustments to get it right. These problems both incur higher labor costs. Thankfully, Deco-Flash has developed a solution.
