  • We recently used Malcolm Carpentry to renovate our bathroom and to do some work in the kitchen. We would offer that if you wish to turn your project into a dream come true rather than a true nightmare, then you want to work with Derek. His professionalism, his creativity, his sense of ethics and his consistency at exceeding expectations, are some of the outstanding qualities we truly appreciated. A contractor who ALWAYS shows up on time, who updates you throughout the project and someone who works with quality subcontractors is what Derek brings to the work - not to mention his consistently pleasant attitude.  Thank you so much Derek!

    Madeleine and Guy,
  • We first met Derek when we needed a tile backsplash installed in our kitchen.  His attention to detail, helpful suggestions and professional service completely won us over and when it was time to find someone to finish our basement, he was our first choice.  His attention to detail, which has been mentioned by previous clients, was true down to the last detail (even going so far as to make sure the door hinges matched the ones upstairs!) and we never came home to a mess.  He handled all the subcontractors needed for the job and we were not only impressed with the quality of their work as well, but felt comfortable having them in our home – which means a lot when you work during the day and can’t be there when there are relative strangers in your home.  He kept us up to date on the progress all through the project and always let us know if there was something we were thinking about changing/adding that would affect the price of the job.  We couldn’t be happier with our basement and the quality of the work!  We have received tons of compliments on it and know we will enjoy it for a long time to come.  We would recommend Derek to anyone who is looking for a job excellently executed for a competitive price, and we will definitely be requesting his services on any other projects that come up!


    Amanda and Patrick,
  • "Derek is a true professional and an absolute pleasure to work with.  He showed up on-site on time every day, and I was always amazed at how quickly the job progressed.  Aside from being professional and courteous, he also finished the job on the day he said he would finish for the price in the original quote.  The job itself (full bathroom reno, remove a wall, refinish old hardwood floors, plus extras) turned out beautifully; Derek truly transformed our 1950's bungalow into our warm, inviting home.  We did a great deal of research, took quotes from a few different contractors and choosing Derek was an excellent decision.  I highly recommend Derek to anyone; I have already done so with a few of my friends."

  • "I was introduced to Malcolm Carpentry through a friend I work with.  Derek has completed several jobs for me including giving my master bathroom a facelift; you would never know it was the same bathroom.  He also installed ceramic tile in another bathroom and hardwood floors in the bedroom and landing, he did a beautiful job.   I was impressed with his honesty, integrity and his attention to detail.  He has a very good work ethic and I would only hire Derek for any future jobs in my house, as I was so pleased with all the work."

    Lesley Ferguson-Blow, Recurring client
  • "I would like to thank Derek of Malcolm Carpentry for the superb work he has done in my home!  Both the main bathroom and my ensuite now look like they belong in a brand new house!  Derek's work is meticulous and everything is very professionally done.  I was particularly impressed with how clean he was throughout the job.  When everything was complete, the only sign of him having been here was my beautiful new bathrooms.  He has been reliable and honest and I wouldn't hesitate to recommend Malcolm Carpentry to anyone who is looking to have work done."

    Kim Carlsson, Bathroom renovations client
  • "We have hired Malcolm Carpentry for 2 separate jobs now and were very pleased with the outcomes of both.  His price is very competitive and the work he does is first rate.  The sub-contractors he used/recommended were all fair priced and also did good work.  I would not hesitate to recommend Malcolm Carpentry to anyone looking at getting work done on their house."

    Jon Zywicki, Recurring client
  • "We always hear about the terrible ones, but here is one that I would recommend in a second.   His name is Derek Malcolm and he was recommended to me by a third party as being "the" guy to get to do my suspended ceiling for finishing my basement.  I had to wait for him to be available to do my work which I actually took as a good sign because only good people have steady work...  those fly by the seat of the their pants guys do just enough to get by day to day.  It was well worth the wait! Derek is polite, motivated, works well with minimal direction and no supervision.   He is very clean (something that is important to me).   Not only is he clean at the end of the job, but he works clean and does not leave you with a big mess to stare at between the time he leaves for the day.  His work is not only excellent, but it is absolutely meticulous.  I would not hesitate to give the highest of recommendations for Derek to do your project and I have every confidence that you will be just as enthralled as I was with the work done."

    John Hebert, Basement renovations client
  • "Malcolm Carpentry created exactly what we were hoping for.  I gave Derek our vision and he brought it to life.  He transformed our old dingy space into an elegant studio that we are now proud of!  His attention to detail made all the difference.   I have already recommended Malcolm Carpentry and will continue to do so.  I look forward to working on more projects with Derek in the future."
