" I have been doing business with the owners of Stone United for approximately twenty years and have had them install granite countertops in my kitchen of homes I have owned in the past and the outcome has always been an amazing transformation. The knowledge and professional work done by Stone United has always kept me loyal to them and I would not consider anyone else to work on my kitchen and bathroom granite projects. "

Had granite put in our kitchen and the installers did alot of damage to our wood work, dishwasher doesn't set in right, and they neglected to tell us to get an electrician to pull out the outlets before granite was installed. I tried to communicate with the workers and none spoke English.. They said they'd come out to see the damage, but never did. And so far won't return our call.. Please don't use this company.. Very frustrating the time and money they've cost us... Bad company.

I just got our countertops installed today and I can't say enough about how punctual & professional each person that worked on our project was. First Edison who stayed in touch over the phone with me through the process. Then Cassie the owner who came on time, gave us a great price and showed up on the day of install to oversee. Also, the two young men who came to install worked well together with the install,, showed up on time and were pleasant. We are so thankful that we went with Stone United. Thank you!!!

However, like most companies in our rating, Stone United may offer personalized terms and discounts on countertop fabrication — especially during national holidays, seasonal promotions, or for large-scale projects.

It’s important to note that the time required to prepare an estimate may vary depending on the company’s current workload, the complexity of the project, and the chosen material. We recommend submitting a request, calling, or messaging the company through our website to get a personalized quote and clarify the current turnaround time.
Does Stone United offer cutouts for sinks, cooktops, or other elements?
Yes, like most professional contractors in the market, Stone United performs cutouts and countertop preparation for various components — both standard and modern. According to our findings, these services are typically included in the overall project estimate. The standard scope usually covers cutouts for sinks (undermount, drop-in, or farmhouse) and holes for faucets or other plumbing fixtures. Additional cutouts — such as for cooktops, hidden or pop-up outlets, built-in wireless chargers, or other accessories — are discussed individually at the project planning and estimating stage.
It’s important to note that while the cutouts and countertop preparation are usually performed by the company, the installation of electrical and plumbing fixtures (such as faucets, outlets, or appliances) may not be included in their scope of work and could require licensed professionals. We recommend clarifying this point when placing your order.
To avoid misunderstandings, ask for a detailed estimate with a breakdown of all services: cutout pricing, installation, and any add-on options. This will ensure project transparency and help you clearly understand what you're paying for.
What guarantees does Stone United provide for its work?
According to our information and industry practice, Stone United, like most participants in the ranking, provides a workmanship warranty valid for 1 year from the date of countertop installation. This period is usually specified in the contract. We do not rule out that the company may have extended warranty terms (2 years or more), however, during our research, we did not receive confirmed data from the contractor regarding the duration and scope of its warranty.
The contractor’s warranty covers defects in fabrication and installation, such as uneven or separating seams, leveling and fastening issues, detachment or sagging of an undermount sink, flaws in edge finishing and cutouts, premature failure of seam materials, and cutouts that do not match the approved design. Warranty coverage does not include damage from use (thermal shock/burn marks from hot cookware, chips or cracks caused by impacts), stains and acid etching (for marble), wear due to insufficient maintenance or lack of sealing, natural characteristics of stone (veins, micro-pores, variations in shade/pattern within tolerances), shifts caused by base deformation, or any modifications performed by third parties.
The material warranty is provided by the manufacturer or the official stone supplier. Engineered quartz brands often offer a limited “lifetime” warranty for residential properties (subject to registration and compliance with care guidelines). For sintered surfaces, typical warranty periods range from 10 to 25 years. Natural stone usually does not come with a factory warranty — its quality of fabrication and installation is covered by the contractor’s warranty. The term and scope of the warranty depend on the project and materials — contact Stone United in any convenient way on this page to get the current terms.
