Google shows 4.8 stars from 199 ratings, with 129 written reviews since 2015 and 14 in the last six months. The praise is specific and repetitive in a good way: showroom and sales staff named again and again — Adriana, Lucy, Rosana, Leslie, Julia, Fabiana — for walking customers from slab selection through templating to install; fast turnaround, with one April 2026 customer templated within a week and installed within two; and install crews (Tony's team, Marcus and Lucas) praised for precision and cleanup. Several reviewers are repeat customers, one with two kitchens done, another an interior designer and realtor who uses them for client work, and one who chose them despite a higher quote on the strength of referrals. A November 2025 reviewer described the shop finishing on time and fixing sizing issues by hand while its CNC machine was down. Two customers said the company came back the same day to trim a counter or answer a question after the stove went in.
Houzz tells a rougher story at 3.5 stars from 17 ratings, and the complaints across both platforms cluster on what happens after installation. In October 2025 a customer described a visibly sloped quartz backsplash shelf and being told that was normal. In January 2026 a reviewer posted photos of failed grout and caulking less than a year after install and called the installation a nightmare. An August 2025 reviewer said there was no help with anything after installation. A March 2023 customer got dull rings and etching on a countertop and questioned whether sealant had been applied. A September 2025 three-star review rated selection and templating five stars but rated the later stages lower. Older Houzz reviews from 2016 through 2020 describe counters that did not fit, a slot cut into a wall and scratched surfaces, late arrivals and disputes over quotes and final billing.
One government action is on record: Good Jobs First's Violation Tracker lists a $17,225 federal Fair Labor Standards Act wage-and-hour penalty against Granite Plus of America Corp. dated October 2015. The listing gives the category and amount only.
For a kitchen or bath countertop, this is a large, well-stocked fabricator whose selection, templating and speed draw consistent praise. Nail down in writing what the post-install warranty covers for seams, caulking, sealing and fit, and ask who to call if something is off after the crew leaves.
