  6. Get an Exact Fit – When your new windows are replaced, it is absolutely necessary that there is just a tiny little room around the perimeter of your window to allow for insulation and shimming.  Our installers fill every crevice with either foam that expands to fill the extra space or fiberglass.  To make sure that every and each crevice is insulated, we usually hold a candle to the new window to check for even the smallest drafts and see if the candle flickers.

  7. Use the Right Flashing –  Your new windows can be very quickly ruined if time is not taken to properly flash them with a drip cap.  We install those drip caps and then fit your window siding over it.   Years ago, drip caps were made out of wood and if they did not have metal above (usually copper or aluminum ), they would rot.  Nowadays, there are products like AZEK Integrated Drip Edge which does not need metal protection, and is designed to assist with water management efforts around windows.drip-cap-window-replacement
