    I contacted Groundworks (formerly Clarke Basement Authority) as I was looking for a company to encapsulate my crawl space. Beginning with the initial meeting with Chris (quoted the job) to completion, the project ran smoothly. Lucio, Tai and Carter were the onsite crew that completed the work. They displayed a high level of organization, were professional, polite and had an excellent work ethic. I had several questions during the quote process and when the job was underway. The responses were always prompt and the time was taken to explain to me the project and how the work was being completed. Lucio, Tai and Carter kept the work area contained and were extremely tidy and respectful of my home. Throughout each day, Lucio provided me with regular updates that included pictures at various stages of the project. Lucio is an excellent project leader and that is reflected in the way the team worked together. I would recommend this team and Groundworks for crawl space work.

  • Floors Done Right Installations Wsib
    Rating: 5 out of 5
    General contractor in Oshawa

    Hi my name is Michael. I have been installing flooring for over 33 years in Durham Region . I install for all the big box stores and flooring stores in Durham Region. I install hardwood, laminate , carpet , vinyl click and vct tiles . My flooring boys and I , also install all new baseboards, quarter round and door stop. At a very affordable rate. My flooring crew and I , are the true professionals. We snap lines. We undercut all door casings . No top pinning the last rows in your wood flooring. We use wood glue and hardwood jacks to close your last few rows without any gapping . We treat ever install, as if we are doing our own house . We take great pride in our craftsmanship. Our workmanship is the best in the industry. In this trade, unfortunately you get a lot of wannabe flooring installers. And some store owners thinking they are installers. Giving you very poor advice. Please note. Most flooring store owners or box store employees , have never installed flooring. Have no clue where to start or how to finish your install. Wrong transition moldings and stair nosings. Over charging you on carpet and underpad.. Watchout for flee market deals . If the back of carpet , the latex peels off. It's defective carpet. On hardwood or laminate specials. Please check the lot numbers. You always want the same lot numbers. They only care about collecting your hard earn money. And not being very honest. Taking a lot of short cuts. Don't get mislead. Please don't let anyone install your new flooring. Without contacting me first. I know where to start my rows. And give you that professional install that you desire. I can give you advice on what products that will give you that wow factor. I take no short cuts and I have no excuses. My goal, is to make your vision into a reality. My crew and I can meet all all your flooring needs. I can recommend flooring stores with warehouse prices . No peer pressure salesman , on commission, who tries to up sale you. Or tries the switch and bait. You purchase a product and get something else at a lower grade. Some flooring stores have hidden restocking fees . No charge for under cutting your door casings charge. Or they make you sign a contract with Hidden costs. Please read the fine print. I am a certified installer. I take great pride in all my installations. Flooring is my passion. No cutting inside your house. I use a laminate cutter to reduce dust in your house. I use drop sheets. I vacuum all rooms before installing . I clean up all garbage. After all my hard suface installations, I use a swifter and a Bona cleaner . I don't accept any deposits or payment until your install is completely installed. I am fully insured. I do have WSIB . I offer free measures. I am available on short notice.
