MaxSeal LLC

We called MaxSeal because we weren’t getting enough heat through the vent in our master bedroom. They are so professional and accommodating. We got an appointment almost immediately and when they arrived, they did a thorough investigation and testing of our heater and all the vent flows.
They actually suggested a minor solution that would not cost us anything. They gave us an estimate for providing their full Maxseal service. The estimate looked good, but we had to put off doing the full service until we can work it into our budget.
Nevertheless, their suggestions worked as a temporary solution, and we look forward to hiring them for the full service in the future.
I commend Alex and his staff for managing a business with integrity and honest professional service, which is becoming harder to find. Often, companies practice a marketing approach where they trick customers into buying or paying for services that are not needed. This is not the case with Maxseal. I completely trust them. They have gone above and beyond to prove themselves reliable, honest, and dependable.

Our utility bills had increased and the indoor air quality decreased over the past few years. I had our mechanical contractor inspect and clean the ductwork and he recommended MaxSeal as a follow up because the ductwork appeared to be in relatively good condition but the duct joints were suspect. MaxSeal responded quickly, tested and sealed the ductwork in one day. Initial test indicated significant air loss into the crawl space. Sealing the ductwork greatly reduced the losses to insignificant amounts. The indoor air quality is great and we expect the utility bill reduction to provide a one year payback. MaxSeal is highly recommended.

MaxSeal LLC did an outstanding job improving my home air conditioning system. From start to finish, they were extremely professional, efficient, and easy to work with. The owner was honest and straightforward, taking the time to explain everything clearly without any pressure.

Their crew was equally impressive—skilled, respectful, and committed to getting the job done right. On top of that, the pricing was very reasonable for the quality of work they delivered. Their company’s solution to improving the ducting system is the best value proposition hands down. To boot, I have medical quality air systems at my home now provides the best peace of mind.

If you’re looking for a reliable company that truly stands behind their work, I highly recommend MaxSeal LLC. They treated my house with respect and made sure the house was clean after the job was done. Best part - you have engineering data that their job was done right as you have pre- and post project results.
