Cornerstone IAQ Services LLC

⭐⭐⭐⭐⭐ I cannot recommend Jason Doyle and his team at Cornerstone IAQ highly enough. He has completed multiple mold remediation jobs and duct cleaning for me and my family, and every single experience has been exceptional. His professionalism, knowledge, honesty, and quality of work are truly second to none. Most recently, when we called, Jason told us he was booked about three weeks out. Despite his busy schedule, he made the time to fit us in and had the job completed within 24 hours. That level of customer service is almost impossible to find today. If you need mold remediation in Southern New Hampshire, Cornerstone IAQ is simply the best of the best. Jason genuinely cares about his customers, stands behind his work, and consistently goes above and beyond. They will make sure to get rid of all mold and that it will not be an issue going forward. You can trust Jason and his team. We will continue to use him for any future IAQ or mold remediation needs and recommend him to everyone we know.

Great service! Jason and his son accommodated us and fit us into their schedule for dryer vent cleaning. They were friendly, prompt, and very efficient. I would highly recommend them!

The Cornerstone team did an outstanding job cleaning and treating my basement after water damage. They are consummate professionals who approached the work with thoroughness and care, delivering a comprehensive solution. From the outset, they understood the urgency of the situation, were highly accommodating in scheduling, and completed both the initial and follow-up work promptly. They also coordinated closely with the inspector to ensure everything met the required standards. I highly recommend the Cornerstone team for any environmental remediation work, great value for the price, you’ll be in excellent hands.

Jason & Chris were fantastic. Very professional, efficient, & polite. Air Ducts were overdue to be cleaned, saw pictures throughout the process. Very impressed and pleased, HIGHLY recommend.

Jason and his Team have cleaned all of our 100 dryer vents at the community that I work at as well some duct cleaning. They are extremely through and always clean up after the job is complete. They are fairly priced and I would highly recommend them to anyone searching for a professional service. We will be using them in the future. Thank you for a great job Jason!
