"Victor got in contact with me straight away and quickly coordinated a time to visit. He listened to all our needs and we worked out a plan for him to return when the weather permitted it (less than a week.) All the work was done to our satisfaction in regards to both time and quality. Victor is a genial fellow, communicative, and a hard-worker. Couldn't have asked for a more pleasant experience."

At Toolbox Dispatch, we understand the importance of a well-maintained home or workplace, and we are here to ensure that every project, big or small, is completed to your utmost satisfaction. Whether it’s a repair, installation, minor renovation, or general maintenance task, you can trust our experienced team to handle it with expertise and efficiency.

"The refurbishing of a master bathroom has been a nightmare. The project was rather simple: remove and replace fiberglass shower/tub enclosure, remove sheetrock and re-install new sheetrock, remove existing vanity sink and replace, install shower faucet and shower head, vanity faucet. They provided an estimate of 8 days to complete the job. It has taken many weeks and not even done adequately. It is so bad that I have to hire another contractor to pull out the shower walls and re-install new ones. They ruined it with their sloppy installation and not following instructions. When they apparently tried to fix it – it just looked worse and worse. Their plumbing sub-contractor made a big blunder and did not seal the pipe for the new tub faucet. This caused water to come through the ceiling onto the first floor and they had to replace a bunch of sheetrock in the kitchen. They removed all the towel bars in the bathroom for the new sheet rock but somehow managed to lose one…and came up with a BS story that there was only one in there. That didn’t fly so the story changed to that it had to be destroyed when the sheetrock was removed. Another BS story as we were in the house when this happened and would have seen it being carried out. The mudding of the bathroom was sloppy, see photo of the light switch. The caulking is even worse – much of it is missing or just very poorly applied. That all had to be removed and re-done. There are too many other issues to list but we’ll be spending another $4,400 to fix the mess they left. I urge you to learn from our encounter and avoid them – it was NOT a professional job, the staff were mostly untruthful and often rude."

"They have now done two separate jobs on different occasions. Jobs consisted of preparing a floor for carpeting after a animal had ruined the previous carpet and wood. Also fixed my front door which was a little crooked so it stuck. I then called them back for drywall work after I had redid my plumbing. Excellent, professional work for both jobs. Well priced. Went above and beyond. Was also very nice and great to talk to. All around great work that I recommend. And I know we will have other projects for this company."

"Excellent company. Jack is amazing, he is nice and friendly and he has a keen eye for design. He is a master craftsman and a perfectionist. Arrives every day on time and always show up, has a wonderful crew that he brings onto the project. I would highly recommend Jack of All Trades for any project, not just bathroom remodel. I was pleased with his work and the price and how quickly he got the project done!"

Jack of All Trades at this time has 2 employees and there may be a need to add more the future. I do not use sub contractors at this time. All estimates are free.

"Steve was recommended by a neighbor who is also in the trades. I called, left a message, he called me back within an hour. After discussing the broken torsion spring and what it would take to replace it - including me sending pictures, he quoted me a very fair price and said he would be able to come do the repair the next day at 10 AM. Next day at 10 AM, there he was on my doorstep. About 40 minutes later the replacement was complete, including some minor adjustments that were also needed, all included in the original quoted price.
