"H&F Exteriors was awarded a contract in July 2023 to replace porches of my daughter's house (front - partial and back - complete) in St Louis. When initially meeting with H&F's Project Manager, Phillip Raphael, I was impressed with his understanding of what we wanted done. It was clearly reflected in the scope of their bid (compared to other contractors) as well as the schematics which used existing pictures of the porch areas with overlays of planned construction. Less than a week after contract award, he set up a group text with himself, me, my daughter and his Production Team. I have dealt with many contractors - both personally and professionally - and must say the communication throughout the entire project was as good as anything I have experienced. Within a month, the Production Team assumed the lead and provided regular updates on material delivery and construction timing. Phillip continued to touch base periodically as well to ensure things were moving forward satisfactorily. Since I live out-of-town from where the work was being done, he and his Team coordinated everything with my daughter and kept me in the loop on progress. During construction, there were a couple issues my daughter brought to their attention and they were quickly addressed to her satisfaction. At the end of the job, a punch list of a few remaining items was completed, all extra materials were removed and the jobsite was cleaned up without any follow-up needed by my daughter. Needless to say, we were extremely pleased with H&F and will definitely be including them on bids for any future exterior improvements."
