Connecticut's Contractor of Choice

Custom Built is a family-owned window and door replacement contractor founded in 1961 that has been providing quality services for 57 years. We are the only company in the entirety of New England that still manufactures its own products. When you work with us you can count on a personalized touch and no middleman, aspects that we have always found important for providing quality services.

We like to let our customers customize their product and so we offer a variety of customization options ranging from color to material to glass insert and hardware options. We also offer free estimates and our skilled and certified installation technicians will help guide you through the whole process. Contact us to schedule your free estimate!

  • Organization: Good organization allows us to effectively use our time, provides clarity on our mission/purpose, and achieve our goals. This is what allows us to have some control over circumstances and events so that we can deliver quality regardless of challenges that may arise.
  • Wisdom: Over 57 years we have never stopped learning despite already having learned much since 1961. A constant desire to learn and the experience and knowledge that this provides have been key to our company’s success.
