From dust, dirt and dander to debris and allergens, any number of potentially harmful particles can get trapped inside your duct system. A dirty duct system will continue to re-circulate this contaminated air and, in some cases, it can escape the system and be distributed inside your home. In other cases, it can stay in your ducts and continue to attract even more dust, increasing the amount of contamination day after day. Our professional air duct cleaning system features powerful vacuum equipment to reach deep into your air duct system, remove the contaminants and help get a dirty duct system working efficiently again.

"Everything went very well. Will use them in the future for preventative maintenance."

Their professionalism, attention to detail, and commitment to quality has created a deep trust in Robert. He is top of our list and we have recommended him and his team to all our family and friends.

His team was respectful of our home and ensured that the worksite was clean and organized at the end of each day. The quality of workmanship has proven to be outstanding and the custom work will last us for years to come. Another impressive aspect of working with Roberto and team was their ability to stay on schedule and within budget. They provided a clear timeline at the beginning of the project and adhered to it, completing the work on time without any unexpected costs. Even after the project was completed, Roberto continued to provide exceptional customer service and followed up to ensure we were satisfied with the work.

Mold Testing and Remediation questions, answered by experts

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

Eliminating mold from wood permanently poses a challenge as the mold spores have the ability to deeply penetrate the porous wood surface. While surface mold can be effectively eradicated with proper cleaning and preventative measures, it's difficult to guarantee its non-recurrence under favorable conditions. To prevent mold from reappearing, it is important to identify and resolve the root cause of the moisture that triggered mold growth initially.

Ensuring appropriate ventilation and a dry environment, or consider applying protective finishes such as sealant, varnish, or paint to prevent future moisture penetration and mold growth. Consistently inspect and maintain the area to keep the wood free from mold in the long term.

Asbestos fibers can stay airborne for 48 to 72 hours, depending on the home's ventilation. Fibers can linger longer in enclosed spaces with poor airflow. Because the fibers are microscopic, they can easily remain suspended, making them difficult to detect without professional equipment.

Yes. Over time, hidden moisture from a leak in your bathroom may lead to black mold, requiring a mold remediation company’s services and the removal of large wall sections, which can be costly. For example, 100 square feet of drywall can cost as much as $400 to replace, while mold remediation can run anywhere from $500 to $3,000.

Higher energy bills, ductwork over a decade old, poor airflow, and noisy ducts are a few common signs of bad ductwork. A moldy smell or musty odor, visual damage, increased allergies, and poor temperature control are other signs.
