Hiring a professional is a smart decision on many levels. A trained eye and skillful hand will clearly show in the beautiful installation, indoor comfort and thermal efficiency of your home. A professional will also be able to make design suggestions to help in the decision process. You’ll want to make sure the contractor you hire is licensed, bonded and experienced. While you may be tempted to install the windows yourself, you may not be prepared for the difficult installation challenges or structural damage to your home that could occur, along with the risk of voiding the window warranty. A professional installer will also be up to date on codes relating to lead, energy, and more.
