  • Very Professional

    Thank you for the outstanding Job! Karel came on time, and finished everything very professionally. Karel later answered questions over the phone. I would recommend DE KONING for anyone with electrical needs.

    - Stefan from Newmarket
  • Reasonable Pricing

    Karel did a wonderful job at installing our chandelier electrical and under cabinet lighting. He was responsive and timely. Pricing was very reasonable. Our inspections passed with flying colors. Would recommend.

    - Sandie from Toronto
  • Honest

    I needed a broken "pull-chain" light fixture replaced and immediately thought of Karel. Despite it being a minor job, Karel happily accepted the work and came the following day and right on time. He is an extremely conscientious, professional and honest individual. I find it hard to find reliable and prompt service these days but Karel stands out. I wouldn't think of anyone else.

    - James from Toronto
  • Definitely Recommended

    Extremely pleased with the service provided by Karel. He arrived on time, provided his quote after reviewing the requirements and completed the job to my satisfaction. I will definitely recommend him for any electrical work, big or small.

    - Ram from Brampton
