    Ultimate Mold Crew helped remediate mold in the attic of one of my properties and I found them to be very professional, responsive, and helpful. They provided before & after pictures along with a certificate of remediation. They were easy to book, accommodating to my schedule, and left the place spotless afterwards. Highly recommend!

    I spoke with Priya when I called to inquire about my concern about possible mould in my basement. Priya was extremely helpful- patient and knowledgeable. All the information she provided convinced me that not only was UMC an expert in this field, but they truly cared about their customers. They exemplify a well run family-owned company!

    Really pleased with the service—everyone was friendly, quick to respond, and did a great job. They came out fast, got everything sorted properly, and worked in a very professional way. Fair pricing too. Hopefully we won’t need them again, but we’d definitely use them if we do. Thanks again!

    I called them for basement waterproofing in Mississauga after noticing moisture on the walls. They did exterior waterproofing and sealed everything properly. Super clean job and very reliable team.

    Had a great experience with these guys doing a mold removal at my home. I'm not posting any pictures cuz it's my home for privacy reasons Please note I had a small job in comparison to some of the other jobs out there. This company was quick to respond to me and and my questions. My contact gave me great advice over the phone and reassured me that the job would be simple and easy which it was. These guys came in at half the price of some of their competitors. These guys also came in at a fair price for the amount of work that they're doing. The quotes were detailed and well set up and not half-assed like some of their competitors. The person that came to my home was professional, honest and awesome. He walked me through every step that he took to deal with the mold. He showed me photos outlining the issues I had the steps she took more or less to fix it and the before and after. You cleaned up after himself left nothing behind. Took everything with him. This company is just awesome. The experience was awesome as well.

    I usually don’t write big reviews, but I had to for these guys. We recently had a major leak coming in from outside into our home and contacted Ultimate Mold Crew. They came the very next day and started right away. They did an amazing job removing all the mold and made sure proper containment and barriers were in place to protect the rest of our home and family. They also walked us through every step, which we really appreciated. During the process, once the walls were opened, we discovered cracks and leaking around our windows that we didn’t even know about. We’re very grateful they were able to identify the root issues and even provide a trusted contact to help fix them. You have an amazing team—very professional. You guys are awesome. Highly recommended!

    We had a substantial amount of mold in our basement, and Ultimate Mold Crew did an amazing job. From start to finish, they made safety their top priority — taking every precaution to protect our family, our home, and the air quality throughout the process. Their professionalism and genuine care really stood out. You can tell they follow proper protocols and don’t cut corners when it comes to safety. We are extremely satisfied with their work and couldn’t be happier with the results. Highly recommend!

    Ultimate Mold Crew did an amazing job with our interior demolition. There was mold everywhere and we were honestly really scared about the situation. From the moment we called, they answered right away, reassured us, and gave us a fair price. Their team worked quickly but still kept everything extremely professional and thorough. You can tell they really know what they’re doing and actually care about doing the job right. If I could give more than 5 stars, I absolutely would. Highly recommend them to anyone dealing with mold issues!

    Easy to book and competitive prices. Johnny was prompt to answer all questions. Dio arrived on time and gave me a comprehensive review of the clean. He also diagnosed and resolved the cause of the mold. Would definitely hire again.

    Helping Toronto Homeowners & Businesses

    Mold Removal As Per Property Type & Location

    Mold problems are not the same in every property. Older basements in Midtown, finished basements in Etobicoke, high-rise condos downtown Toronto and Brampton, attic ventilation issues in North York, and humidity problems near the waterfront can all require a different inspection and remediation plan. In high-density condos and apartments, mold frequently appears around windows, fan coils, bathrooms, and laundry closets. Whether mold appears after basement leaks, foundation seepage, plumbing failures, or condensation behind finished walls, our team can inspect the area and recommend the right next step.

    End To End Attic Mold Removal

    Attic mold often comes from bathroom fans venting into the attic, roof leaks, blocked soffits, poor insulation, or weak ventilation. We inspect sheathing, rafters, insulation, and ventilation before recommending removal. Our attic mold removal services safely eliminate mold while addressing the root cause. We identify ventilation issues, correct moisture buildup, and ensure your attic remains mold-free long-term.

    For Commercial and Rental Properties

    For offices, retail units, rental homes, multi-unit buildings, and managed properties, we provide clear documentation, scope of work, containment planning, and remediation support.

    Questions We Often Hear

    Most smaller mold remediation jobs take 1 to 2 days. Larger jobs involving containment, demolition, drying, cleaning, disposal, or testing may take longer.

    Yes. While our primary hub serves the Greater Toronto Area (GTA), we provide full-service mold inspections and certified remediation across Brampton, Etobicoke, Mississauga, Vaughan, and surrounding municipalities. Our local teams are strategically positioned to handle residential and commercial emergencies quickly.

    Most residential mold removal projects in Toronto take between 1 to 3 days to complete. The timeline depends on the containment size, the depth of material penetration, and the drying time required for structural drying. We do not pull down containment barriers until air quality tests confirm that spore counts have returned to safe, normal levels. 

    To save you time, we offer a Free Video Call Mold Inspection. You connect live with one of our certified mold technicians via your smartphone. You show us the problem areas, and our expert will analyze the visible growth, discuss potential moisture sources, and determine if an on-site physical inspection or air quality testing is required.

    Detect mold by identifying musty odors, dark spots, water stains, and humidity above 60%. Mold often hides behind walls and ceilings. Professional inspection confirms hidden growth using moisture meters and air testing.”

     

    Ask yourself:

    1. Do symptoms ease when you leave a certain room?
    2. Do you feel better while at work or outdoors?
    3. Do symptoms return within minutes of re-entering your home?

    If the pattern repeats, hidden mold could be the cause. Quick mold remediation helps restore indoor air quality and reduces ongoing health problems.

    Yes. We handle mold in condo bathrooms, fan coil areas, window frames, laundry closets, kitchens, storage spaces, and exterior wall areas.

    Mold testing is not required in most cases. Visual inspection identifies contamination and determines removal methods. Testing helps in complex cases to confirm mold type and spread, especially in hidden or large-scale infestations.

    Yes, if the moisture source is not fixed. Good remediation includes removal, cleaning, and moisture-source correction.
