    How long will it take to repair my window or door?

    The duration of the repair process depends on the complexity of the issue. For minor repairs, we strive to complete the job in a single visit. However, some repairs may require additional time if specialised parts or materials need to be sourced. Rest assured, we will provide you with an estimate and keep you informed throughout the repair process.

    Can you repair any type of window or door?

    Our expertise lies primarily in repairing UPVC windows and doors. While we excel in addressing issues with UPVC products, including mechanisms, seals, and glass replacement, we regret that we are unable to extend our repair services to timber or Aluminium windows and doors. Our specialized focus ensures that we deliver the highest quality repairs within our area of expertise.

    Yes, we proudly serve the entirety of the South West region, including Devon and Cornwall. No matter where you're located in the area, you can rely on DNA Window Solutions to provide efficient and reliable repair services for your windows and doors.

    Absolutely! Our sealed unit replacement service is specifically designed to address misted, cracked, or broken glass units in windows and doors. We supply and fit high-quality sealed units that match the existing frames and styles, ensuring a seamless replacement that enhances the appearance and efficiency of your glazing products. However, please note that our services are tailored specifically for either UPVC or Aluminium frames. Regrettably, we are unable to replace faulty glass in timber frames at this time.
