What to expect when you deal with KOTT

  • We’ll work from your plans to provide you with a quote on the type and style of windows that your Architect or Designer has specified.
  • Our comprehensive quote will give you detailed specifications on each window and door, including the exact dimensions and your choices for glass, hardware, screens and finishes, along with a thumbnail visual representation.
  • When you sign the contract, we’ll ask you for a deposit, payable by cheque, Visa, or Master Card.
  • Once we have your signed contract and deposit, we will order your custom windows and doors from the factory. Expect 4-6 weeks for them to be made-to-order and shipped. Once they arrive, we’ll call you to schedule delivery.
