Patios, retaining walls and stone work are what Prevail Construction builds, according to its customers. The Abington hardscape and masonry company at 284 Oak St is run by Deni Da Silva, per its Angi and HomeAdvisor profiles; reviewers spell it Denny or Deni. It holds 5 stars from 11 ratings on Google and 5.0 from 19 on Angi and on HomeAdvisor. The largest job in the reviews is from June 2026: the crew custom-made a fire pit, built an outdoor kitchen, installed a 2,000+ square foot patio and a 75-foot walkway, and finished with a granite-covered deck. In a May 2023 Google review, a customer said the company built a 140 ft. front yard retaining wall in the two days promised, and when excessive concrete turned up under the old wall, Denny brought in extra heavy equipment on a Saturday to stay on schedule. A March 2023 customer had a crumbling retaining wall replaced and called the estimate fair, "with no surprises." A June 2024 reviewer had an outdoor chimney refaced with fieldstone. A customer who first hired the company in 2021 for a pool retaining wall and porcelain tile came back in 2023 to replace a raised wooden deck with interlocking pavers. The older Angi reviews, from 2016 to 2018, describe the same kind of work: a May 2016 customer had a collapsing wall torn down and three walls rebuilt.
Can’t thank Denny and his team enough for coming to my home and improving its quality and look. These guys were easy to work with, friendly and hardworking. I will hire again and refer to all.
I can’t say enough great things about Prevail Construction! From start to finish, they were absolutely top-notch. The quality of their work is outstanding, their communication is excellent, and everything was handled in such an organized and professional way. Denny and his team completely transformed our outdoor space. They custom-made a beautiful fire pit from scratch, built an incredible outdoor kitchen, installed a 2,000+ square foot patio, created a 75-foot walkway, and finished it all off with a beautiful granite-covered deck. Every detail came out amazing. They were easy to work with, reliable, and made the entire process smooth and stress-free. Denny, the owner, is truly one of the nicest guys around and clearly takes tremendous pride in his work and his customers. I would highly recommend Prevail Construction to anyone looking to support a reliable, honest, and high-quality small business!
Extremely happy with the work done refacing our outdoor chimney with fieldstone. Denny’s team was professional, punctual and did a very nice job cleaning up the work area. Would most definitely recommend.
