Valenza Construction is well prepared and positioned for large or small jobs. They are intelligent contractors who think through solutions and offer options to homeowners. As an architect, the attention to detail is important to me, and I feel that the craftsmanship that Valenzano offers is superb.

THE BEST!! Valenzano Construction has done so many jobs for me and friends I have referred them to. Every one of Darrens workers and subs are equally as qualified and hard working. I cannot recommend Valenzano Construction enough.

We recently completed a full house remodel—including a completely gutted and reimagined kitchen—and we truly couldn’t be happier with the results. Working with Valenzano Construction was an absolute dream from start to finish. Not only was the craftsmanship top-notch, but the level of communication, professionalism, and attention to detail was beyond what we could have hoped for. They stayed on schedule, respected our budget, and offered creative solutions that made the most of our space without cutting corners. Our kitchen is now a total showstopper—functional, beautiful, and so thoughtfully designed. The entire house feels brand new and totally us. If you're looking for a contractor who is honest, skilled, and genuinely cares about the quality of their work, Darren is the one. We’d work with them again in a heartbeat!

Where this page comes from
Every figure above is Google’s, captured on 24 September 2026. The star average and the 5 ratings behind it are counted by Google across all of its reviews. The review text on this page is a sample — we hold 5, of which 5 have any text — and it is not everything Google shows.
Roof Warden does not verify licenses, bonds, insurance or workers’ compensation cover, and nothing on this page should be read as though we had. Confirm those directly with the contractor and with your state or provincial licensing body before you hire anyone.
There is not much data on Valenzano Construction. A short record here means our capture found little — not that there is nothing to find, and not that the business is new or inactive.
