  • "We had The Small Sash Window Company come to service our timber sash windows. We also had their window locks fitted. We had never seen these before, but we were very impressed with the functionality. We were lucky to find this company and they continue to work with us."

    Facilities Manager, MLC School Burwood.

  • "We needed window locks fitted for safety and to enable ventilation for the wellbeing of our students. The Small Sash Window Company installed their window locks, and we were very happy with the outcome. They look great and are simple to use."

  • "Keith did a great job installing our sash window locks. Keith was personable and really great to work with. He was passionate, polished and very professional. I would recommend his service to others."

    Simon - Mosman

  • "Keith Colthart, proved to be an excellent choice to undertake the precision installation of two arched doors at our historic church. Keith is a craftsman who takes pride in his work, not content unless everything fits and operates perfectly. Old deep hardwood jambs had to be removed, new ones installed and the doors needed to be hung. Keith attended to the detail required to get the hinged arched doors to swing smoothly and precisely: a complex procedure. Keith returned to do final adjustments to ensure a perfect fit. I am very pleased to recommend him."

    Ken - St Luke's Anglican Church Burwood

  • "Thanks very much for repairing our 1964 sash windows. I was impressed, that you provided a quote right away, that you arrived on site when you said you would, you repaired the windows efficiently, and cleaned up afterwards. These days that is a rare trait of "tradies". I won't hesitate in contacting you next time we need some work done. Thanks again."

    Michael - Forestville

  • “Keith Colthart Carpentry completed a fantastic job repairing broken window fittings for our school. Keith kindly rearranged his work schedule to complete this urgent job due to weather and security concerns and not being able to operate the classroom windows. Keith was very helpful and professional in his dealings with us. I would thoroughly recommend Keith Colthart Carpentry for window repairs."

    Paul - Randwick

  • “Great customer service - honest and thorough along with a great product - sash window locks. A definite recommendation from me. Thanks Keith.”

    Nick - Roseville

  • “We just wanted to say thank you for the great job you did yesterday. We came home to find beautifully installed locks that function exactly as you said they would, with no damage to any of the existing windows and no mess! And as simple as this sounds it's not something that gets done right by tradespeople very often. I know you have the top floor apartments to complete in the coming weeks and I'm sure our neighbours will be just as happy as we are when it's all done. Apologies again for taking so long to get organised on our side, but it was well worth the wait."

    Julia & Luke - Mosman

  • “Keith serviced our sash windows and installed child safety locks. He was friendly, thorough and took great care to respect the heritage nature of our building and help us select discreet locks. Love your work Keith!"
