Both of these Connecticut businesses score well against our methodology and come up as real options for new construction window installation, but they're built for different jobs. Best Glass LLC is a small, owner-run glass shop known for fast turnaround and custom work, while Renewal by Andersen is a national window replacement brand running large crews on a proprietary material system. The right pick depends on the size and standardization of the build.

Verdict

Renewal by Andersen fits better for larger new-construction jobs that need a standardized, warrantied window system installed by multiple crews without disturbing new trim work. Best Glass LLC is the stronger call for smaller builds or jobs with custom window and glass shapes, where an owner-run team can move fast and keep pricing straightforward. Neither score should override which one matches the scale and shape of the actual build.

Which should you pick?

Pick Best Glass LLC if

  • The build has custom or irregular window openings that need a glass shop's flexibility
  • You want the owner directly overseeing the job and fast scheduling
  • You'd rather keep costs down with a smaller, fair-priced local team

Pick Renewal by Andersen if

  • The project involves many standard window openings across a new build and needs crew capacity to match
  • Matching new trim and finish work precisely is a priority
  • You want a warrantied, engineered window system rather than a mix of standard units

The differences that matter

  • Crew scale for volume. Best Glass is managed personally by owner Fernando with a small team, while Renewal by Andersen fields multiple named installation crews (Ryan, Greg, Janek, Reg, George) built for higher-volume jobs.
  • Window system and material. Renewal by Andersen installs its own engineered Fibrex windows with a backed warranty, while Best Glass works with glass and standard window units rather than a proprietary system.
  • Trim and finish integration. Andersen crews are specifically praised for precise measuring and preserving existing trim and finishes, a detail that matters when windows have to match new-construction millwork.
  • Handling non-standard shapes. Best Glass is called out for tackling custom requests like angled shower doors without hesitation, suggesting more comfort with unusual window geometries than a standardized brand line.
  • Pricing approach. Best Glass is repeatedly described as fair-priced with extra work done at no added cost, while Andersen runs a structured sales consultation around premium materials and warranties.
