Zach did a great job cleaning, pointing and sealing my cultured stone chimney. He was also very careful around the plants and shrubs which was much appreciated!
Flex Masonry replaced my old, wooden basement steps with solid, cement steps designed on-site with cemented blocks and concrete. They look great and are super sturdy. I found this company to be a pleasure to work with and I would use them again for any masonry work needed. Highly recommended.
Zach did an excellent job repointing my foundation. He is talented and knowledgeable. He matched the mortar of the existing work perfectly. We will definitely have him back to rebuild our chimney!
Flex Masonry did an awesome job with stone veneer work to give my house a facelift! My house went from drab to beautiful! We also had the front walkway renovated and just love how everything came out. Zach has great ideas and can see the final picture like an artist with his canvas. I highly recommend!
Flex Masonry has come to my house multiple times for various masonry work and has always exceeded my expectations. He’s timely and finishes the job in the timeframe he gives. One of the best masonry companies in this area and a true value to our community.
