Will I need to modify my windowsills?
No. Only our WindowCandles can be installed on any windowsill. Many builders only use our low voltage window candles because only our product easly installs without costly trim work. Our system doesn't require building out the windowsill or any other trim modifications. DO YOUR HOMEWORK. Other line voltage or 110VAC candles can be done, but the trim work required usually costs twice what the candle costs! If it's a retro fit, forget it, trim work, drywall patching, what a nightmare. Our system only recesses 1/4" in the windowsill and the sill only needs to be 2" wide. EASY, EASY, EASY!!!
