I had an excellent experience working with Luca from Mold Busters. He was extremely practical, knowledgeable, and diligent throughout the inspection. He approached the inspection in a very professional and thorough manner, taking the time to explain his findings clearly and provide valuable insights along the way. What I particularly appreciated was Luca’s practical approach. His advice was thoughtful, realistic, and focused on helping me understand the situation and the appropriate next steps, rather than simply identifying problems. He was also very attentive to detail and clearly took pride in doing a comprehensive job. Luca brought a high level of professionalism and expertise to the inspection, and his guidance was extremely valuable. I would have no hesitation recommending Luca and Mold Busters to anyone looking for a knowledgeable, thorough, and trustworthy professional.

They they were fantastic. Everyone involved was professional, respectful, and efficient. Just don’t speak to the automated service, wait until you can speak to someone directly. But after that’s in place, the rest of the service is excellent.. very happy and will use them again soon. ( I’m in real estate and my clients need this phone number). Valerie

Excellent experience working with Mold Busters following flooding in the basement of one of our rental properties Even though there were literally thousands of homes affected in the Ottawa area following the historic rain fall on Canada Day, we were able to book Mold Busters in a timely manner for the inspection. Once the inspection was completed, we were given photos and a very detailed description of what would be involved in the remediation process. Once our insurance company gave their approval, a date was set The company arrived on time and proceeded to accomplish everything that had been previously outlined. The job was completed on time and again a detailed description accompanied by photos confirming exactly what had been done as required by our insurance company. . A very professional company with great communication from start to finish. I highly recommended this company and they would be first on my list to call should we be in a similar situation again. Thank you Mold Busters for the excellent work that will help our tenants feel confident in moving back in to their home.

We highly recommend Mold Busters! Luka and Jovan were my contacts. They truly responded lightening fast and above and beyond my expectations. It was much appreciated how their team was able to accommodate us in our urgent situation. It was a challenging time for us, but it was clear that we were in good hands from the beginning. The team (sorry I don't remember their names) were punctual (despite a long drive to our rural location), professional, personable, communicated well, were respectful of our property. They did a great job of containing the area and discreetly removing the mold and affected items. A helpful family member of ours found Mold Busters online and they were the first to respond among all the places we called, (who all had long waiting lists). Luka and Jovan honoured the estimate they gave us. Thank you Luka and Jovan. Please pass along our compliments to the team you sent. They worked hard for hours in a confined space on a hot day in those hazmat suits, and they had a long ride home, but they left with smiles on their faces. They represented the company well. Wishing you all the best.

I cannot praise this team enough. I found a really bad mold infestation behind one of my walls and was worried about the safety, how to remove, cost, and the whole process. Mold Busters responded right away, provided a super easy free app based video consultation and reassured me every step of the way. Every step of the way I was updated with personal text messages and give multiple ways to contact someone if I had any questions or concerns throughout the entire process. Their technicians were super friendly and professional. They minimized any structure removal and left really clean cuts in the drywall to make repairs much easier. Everything was cleaned and they even called me when they decided the baseboard on the wall should be removed just so I would be updated on the process and their findings. This is an absolute 5 star service from start to finish and I’m so happy I chose Mold Busters.

🛠️ Mold Removal Services

At Mold Busters, we offer a comprehensive range of mold removal services tailored to the unique needs of Longueuil residents. Whether it’s a hidden mold problem in the attic or a recurring issue in the basement, we have the expertise and advanced equipment to handle it all. Here’s a closer look at our specialized services:

Basement Mold Removal
🏠 Attic Mold Removal

Attics are often prone to mold growth due to poor ventilation and roof leaks, making them ideal breeding grounds for mold spores. Mold in the attic can go unnoticed for years, leading to extensive structural damage and poor indoor air quality.

Our Approach:

  • Comprehensive Inspection: We perform a thorough inspection to identify mold presence and its root cause, such as ventilation issues or leaks.
  • Targeted Remediation: Our team uses specialized equipment and eco-friendly products to remove mold from all affected areas, including rafters, insulation, and sheathing.
  • Preventive Measures: We provide solutions like improved ventilation and moisture control to prevent future mold growth.

Why It’s Important: Attic mold can quickly spread to other parts of your home, compromising air quality and structural integrity. Prompt removal is crucial to protect your home and health.

Basement Mold Removal
🏚️ Basement Mold Removal

Basements are particularly susceptible to mold due to their below-ground location, which often results in high humidity levels and moisture intrusion. Mold in the basement can cause unpleasant odors, damage to stored items, and health issues like allergies and asthma.

Our Approach:

  • Detailed Assessment: We conduct a detailed assessment to identify moisture sources, such as foundation cracks or poor drainage.
  • Safe Mold Removal: Using HEPA vacuums, air scrubbers, and non-toxic cleaning agents, we remove all traces of mold from your basement walls, floors, and ceilings.
  • Waterproofing Solutions: To prevent future problems, we offer waterproofing solutions such as sealants and sump pump installations.

Why It’s Important: Mold in the basement can easily spread to upper levels, contaminating the air and affecting your family's health. Addressing basement mold issues early is key to maintaining a healthy living environment.

Crawlspace Mold Removal
🛠️ Crawlspace Mold Removal

Crawlspaces are often overlooked but can be a significant source of mold due to damp conditions and limited airflow. Mold in crawlspaces can cause structural damage and elevate indoor humidity, promoting mold growth in other areas.

Our Approach:

  • Thorough Inspection: We inspect the crawlspace for mold, moisture, and potential entry points for water.
  • Effective Remediation: We use advanced techniques to remove mold from joists, beams, and subfloors. This includes applying antimicrobial treatments to prevent regrowth.
  • Encapsulation and Ventilation: To protect your crawlspace from future mold issues, we offer encapsulation services and install proper ventilation systems.

Why It’s Important: Mold in the crawlspace can go unnoticed but may lead to significant structural damage and poor indoor air quality. Regular inspections and professional mold removal are essential to safeguard your home.

What You Walk Away With in Longueuil

On the South Shore, where river humidity meets a housing stock that ranges from postwar Greenfield Park bungalows to Vieux-Longueuil buildings with original ventilation, the real question is not whether the mold looks gone. It is whether you have proof, and whether the fix holds.

Documented clearance before we sign off

Saint-Hubert homes built decades ago hold moisture behind finished basement walls where a quick look finds nothing, so once remediation is complete we do not rely on one. Instead the treated area is tested, with lab air sampling where clean air results are realistic and on-site swabs where they are not, and clearance testing is included in your quote. Photos of the work travel with your clearance confirmation. A formal clearance report is available on request. If drainage against a low-lying foundation or an unresolved leak is still feeding the problem, we say so instead of closing the file early.

Backed by a transferable work warranty

On qualifying Longueuil projects, our work can be backed by a conditional work warranty of up to 5 years, and it transfers if you sell, which matters across a South Shore market where duplexes and condos change hands often. The condition is straightforward: it applies when the full recommended scope is completed. In a home near the river, treating a surface without correcting what is feeding the moisture is exactly what brings mold back, so we map the source during the inspection rather than working around it.
