# Titans Building **Trade:** General Contractor / Remodeling · **Phone:** (603) 300-3380 · **Website:** http://www.titansbuilding.com/ · **Languages:** English **Rating: 4.3/5** (medium confidence) — from 24 reviews across 5 sources. 96% of sentiment-scored reviews read net-positive. Last 6 months: 3 reviews, 0 negative. ## The honest read Titans Building is the kind of contractor homeowners call for projects that cross several trades: kitchen and bathroom renovations, additions, decks, framing, painting, flooring, and broader home construction. The company says it handles ADUs, home building, and residential and commercial construction, with more than 20 years of experience; it identifies Diogo Queiroz as CEO, alongside a project manager and an administrative manager. Older Google reviews describe the work in concrete terms. Homeowners hired the team to rebuild a 12-by-25-foot deck, remodel kitchens and bathrooms, rework a first-floor layout, frame a house, build an addition with a four-season room, and complete a third-floor buildout. They repeatedly mention coordination across specialists, attention to detail, communication, and finished work that matched the plan. A 2026 review also describes a completed construction project and praises the team's process. There is one substantive counterexample to ask about. In an April 2023 Google review, a homeowner described poor communication, missed follow-through, and difficulty locating workers during a large addition; that account is specific and should be discussed before booking. The rest of the written reviews are strongly positive, but most detailed project accounts are from 2022–2023, so confirm who will supervise the work, which subcontractors will be involved, and how schedule changes will be handled. Titans appears best suited to homeowners planning a substantial remodel, addition, or custom build who want one team coordinating several scopes. Ask for a written scope, schedule, and responsibility map before work begins, especially on a multi-trade project. **Strengths:** - Multi-trade builds — reviews describe additions, framing, remodeling, and project coordination - Detailed finishes — homeowners cite attention to detail and finished results - Project communication — many reviews praise responsiveness and clear coordination **Concerns:** - Communication follow-through — one 2023 addition review described missed callbacks and worker-location confusion ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - The company says it offers kitchen and bathroom renovations, ADUs, home building, and residential and commercial construction. _(confidence: high)_ - [Official Website](http://www.titansbuilding.com) — “Titans Building offers kitchen and bathroom renovations, ADU and home building, and residential and commercial construction, with more than …” - The company identifies Diogo Queiroz as CEO and names project and administrative managers. _(confidence: high)_ - [Official Website](http://www.titansbuilding.com) — “Ownership (self-reported): Diogo Queiroz is CEO; Fillip Queiroz is Project Manager and Kelly Queiroz is Administrative Manager.” - Homeowners describe deck replacement, kitchen and bathroom remodeling, framing, additions, and multi-trade renovation work. _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT20wMVQyeERaall3VlRaTk5IVTBNR1I2Y0RneVdXYxAB!2m1!1s0x0:0x18ce4e9292d27720!3m1!1s2@1:CAIQACodChtycF9oOm01T2xDZjYwVTZNNHU0MGR6cDgyWWc%7C%7C?hl=en) — “5★ Upon recommendation of a relative we contracted with Diogo to replace our 12’x25’ deck.
