### All 5 reviews

**★ — HU-522911331, March 2026**

> I cannot recommend working with Charles Malafaia. We had a negative and emotionally exhausting experience dealing with him. I realize everyone has different experiences, ours was not good.

**★★★★★ — HU-695615466, Aug. 2025**

> International Builders and specifically Marcel Malafaia have done a fantastic job on several projects for our family’s home, including a full kitchen gut and remodel when we first moved in plus new floors, interior painting, and exterior improvements. Marcel is highly knowledgeable, responsive, and collaborative, and his team delivers the highest quality craftsmanship consistently. Each time working with Marcel and IB we felt we were looked after attentively and honestly, with no efforts spared to give us the very best result possible.

**★★★★★ — lino532, Sept. 2024**

> International Builders has done 3 projects for us in the last 5 years. Their craftsmanship is top knot as is their commitment to your project. If you are looking to renovate, remodel or build new give them a call you won’t regret it. Thanks for everything Charlie and Marcel!

**★ — HU-560925686, Jan. 2024**
