    Build pergola, gazebo or garden house-
    They were fantastic to work with from start to finish. They installed a gazebo in our backyard. They arrived on time, were professional and left the area clean and tidy. What stood out most was their friendly attitude and professionalism. I would highly recommend Barradas Carpentry.

    Tao came to my house to give me a free quote to fix some holes in drywall and paint the areas. He was very respectful and provided me a quote quickly with a fair price. When he and his partner showed up to do the work, they took off their boots and were as quiet as possible while working. They finished the job and left the area cleaner than when they arrived. I am very satisfied with their work.

    Drywall-
    Deniz just finished his job for me and I couldn't be happier. He did everything we asked and threw in a couple of extra jobs that he noticed needed to be done at the agreed upon price. Drywall fixing with no mess, baseboards updated, vinyl flooring, with full painting of walls, ceilings, and even fixed some broken porcelain tiles from a previous plumbing mishap. Him and his crew worked long days until the job was one. I will be calling him again for other jobs. Sterling in Lorne Park, Mississauga.

    Install or replace garage door-
    I had to have a tension spring changed on the garage door. The change went smooth. He showed up early and got the job done quickly. I wasn’t tied down, waiting hours for them to come. He also saw some deficient rollers and changed them without asking. The advice he gave on how to keep the garage working smoothly was much appreciated. He then left me with a new remote to better operate the doors, no charge! I will be using Global Improvements again if needed!
