Aircraft
During the initial climb as we were climbing to 9;000 feet as directed by ATC it was noticed that the aircraft was not pressurizing. Our Delta P was at 0.2 and Cabin Pressure at 8;500 feet. We immediately agreed we shouldn't climb any higher than 9;000 feet and I then delegated tasks to ensure our safety as we ran a QRH and associated checks. ATC was more than accommodating with us at a lower altitude direct ZZZ. We ran fuel numbers and saw we would land with well above our standard divert should we remain at 9;000 feet the entire way. The cabin reported that there was no unusual activity and I briefed the FA on the situation. Company was contacted via ZZZ Radio via PRESTO Radio after attempts to contact Dispatch as outlined in our guidebooks yielded no results. Dispatch was appraised and Maintenance had me attempt manual pressurization which failed. It was learned the following day that the seal around the cargo door had failed. After discussing all available option and considering the pros and cons of the options as a crew; along with the support of Dispatch and Maintenance we then continued to our destination as the cost of a longer flight duration. There were no further abnormalities or incidents during this flight.
EMB-145 Captain reported a pressurization problem that caused the flight to continue to destination at a low altitude.
