  • Put up TV on wall

  • wall hang tv

    Fabulous job. Would certainly recommend Kelvin to anyone.

    Lovely chap did everything we wanted and more. I had thought about tackling it myself. But so glad I did not. Quite tricky with a big 60 inch TV if you dont know what you are doing. And the wires a nicely hidden. Tidy job. Lots of helpful advice and quite reasonably prices.

    Many thanks, Kelvin.

  • Install Projector and Projector Screen

  • Install receiver & speaker system and ceiling speakers

    Kelvin did an excellent job in setting up all of my AV equipment in two rooms. He was very tidy and polite and completed the job efficiently in about half a day.

    I would recommend Kelvin for AV installation services.

  • Surround sound and projector install - Dalston

    Job left incompleted. Speaker wires left hanging bare out of wall which shorted out the AV receiver. Speaker bracket filled with plaster and paint leading to bad electrical contact. I've had to fix these issues myself and been advised the extra work on light fitting carried out is in violation of building regulations as its on a 5amp circuit. Will now have to find someone else to replace those sockets and check circuit. Kelvin has not been able to contact via phone, email or here since.

    I couldn't be happier with Kelvins work or recommend him more. He even managed to put the TV in the wall (an incredibly thick wall!!). It looks amazing and was not an easy job at all.
    He's done such a great job and a pleasure to have in the house he's coming back to sort out our internet.

  • Multi-room TV set-up

    Would recommend Kelvin without hesitation. Helpful advice during his visit to discuss the works required for the quote; competent and up-to-date product and technological knowledge.

Pricing very reasonable - great value for money.
