## The honest read

Tatra Building Company is a South Yarmouth general contractor run by Jan Kvietok, working on Cape Cod for over two decades according to its own website, with a state-verified active Massachusetts home improvement contractor registration. The company keeps HVAC and electrical specialists on staff — Kenneth Brown as electrical director and Jan himself NATE- and EPA-certified — and its project list runs from kitchen and bathroom remodels to additions, decks, HVAC installs, plumbing repairs and custom new construction.

The most detailed reviews are from 2024. One from October described using Tatra for 'a number of projects — big and small,' including central AC installs, boiler replacements, appliance installs in an old house's tight spaces, an outdoor shower and stone deck build, and routine plumbing fixes. Another from May described a heat pump install running across two floors of an occupied home, with the reviewer calling the crew clean, quiet and punctual throughout — notable for a job of that size.

The written record runs back to 2008 and is mostly positive across that span too. A 2015 review described a full kitchen-and-two-bath remodel with structural beam work as excellent, if 'somewhat expensive.' A 2013 review recalled Jan building a four-season room addition, foundation and framing included. The clear exception is a 2020 review describing a home rebuild that took more than two years, with unmet promises, added charges along the way, and work that had to be redone because it wasn't well supervised — a serious complaint worth asking about directly, even though nothing like it shows up in the reviews before or after it.

For a kitchen or bath remodel, an HVAC job, or a broader renovation on the Cape, Tatra has a long history of well-reviewed work and a currently active license behind it; the 2020 account is the one thing worth raising directly before signing on for anything large or long-term.

**Strengths:**
- Multi-trade shop — handles HVAC, plumbing and electrical under one roof
- Clean, punctual crews — 2024 reviews cite quiet, on-time HVAC installs
- Full remodels done well — a 2015 review praised a kitchen-and-bath project
- Active state license — Massachusetts registry verifies the HIC registration as active

**Concerns:**
- Years-long rebuild — a 2020 review described repeated delays and rework
