I called Tony and not only did they guarantee to complete the quartz counters by the deadline but they beat the competitors prices. He picked up the slabs from the warehouse and made all the cuts perfectly. Great job guys. Highly recommended.

I was looking for someone to help me with countertops. Gustavo did a great job. Within a couple of days he installed the plywood, bought the prefabs I picked and installed everything. Very clean job. Try to find the seam in the photo. The price is very pleasant too. I will recommend him to all my friends.

Does Harbor Stones have its own countertop fabrication facility?
As part of our independent research, we attempted to determine whether Harbor Stones has its own natural stone countertop fabrication facility. Our analyst contacted the company as a mystery shopper, but unfortunately, we were unable to obtain a clear answer — the calls and messages either went unanswered or did not provide the necessary information.
The absence of confirmed data about fabrication should not be seen as a negative sign. In our experience, it is not uncommon for companies to miss some incoming inquiries or choose not to disclose such details during initial contact.
Does Harbor Stones offer any discounts on countertop fabrication in Gardena, CA?
Unfortunately, during our independent research, we were unable to reach representatives of Harbor Stones to clarify information about possible discounts. The company did not respond to calls or messages sent by our mystery shopper. However, in our experience, most companies featured in our rating are open to discussing personalized terms.
We recommend checking the details directly: submit a request, call, or message the company through our website — and be sure to ask about any available discounts. In many cases, contractors are willing to discuss individual terms.
What is the price category of Harbor Stones in Gardena, CA?
Unfortunately, as part of our independent research, we were unable to obtain pricing information from Harbor Stones. Our mystery shopper attempted to contact company representatives to request a quote for the fabrication and installation of a stone countertop measuring 83.4 square feet. However, they were either unable to reach anyone by phone, or never received the promised estimate after the initial conversation.
We want to emphasize that the lack of response or data does not necessarily reflect the quality of the company's work. In our experience, some contractors are simply unable to respond to all inquiries in time or prefer to discuss pricing only in person. To get accurate and up-to-date pricing for your project, we recommend reaching out to the company directly through our website — submit a request, call, or message them — and ask for a personalized quote.
Can I get a free consultation and a free estimate for the fabrication and installation of a countertop from Harbor Stones?
Yes, according to our research, Harbor Stones offers free consultations and project estimates — this is standard practice across the industry. Like most contractors in our ranking, the company provides free on-site measurements, advises on material selection and configuration, and prepares a detailed quote for the fabrication and installation of your stone countertop.
To receive a consultation and a free estimate for your new countertop, submit a request on our website, call the company, or send a message via messenger.
What is the fabrication and installation timeline for a countertop at Harbor Stones?
Unfortunately, as part of our independent research, we were unable to obtain information about the turnaround time for countertop fabrication and installation from Harbor Stones in Gardena, CA. Acting as a mystery shopper, our analyst attempted to contact company representatives to clarify the timeframe for a standard 83.4 sq. ft. countertop project — however, either the calls and messages went unanswered, or the staff were unable or unwilling to provide an estimated completion time. It’s important to note that situations like this are not uncommon: contractors may be overwhelmed with work, prefer to discuss project details in person, or choose not to disclose information during the initial contact.
To get up-to-date information about the turnaround time for your project, we recommend reaching out to the company directly through our website — submit a request, call, or send a message via messenger to receive a personalized estimate and confirm the actual timeframe.
How long does it take Harbor Stones to prepare a quote for countertop fabrication and installation?
Unfortunately, in the course of our mystery shopper research, we were unable to obtain information about the quote preparation time from Harbor Stones in Gardena, CA. Our analyst may not have been able to reach a company representative, or the quote was never provided after initial contact. As a result, we are unable to objectively evaluate the company’s quote turnaround speed. This situation is rare and usually related to temporary workload or internal processing specifics. It does not necessarily indicate a low level of service — it simply means that we didn’t receive a response within the research timeframe.
To get up-to-date information, we recommend contacting the company directly through our website — submit a request, call, or message them to receive a personalized quote and clarify current pricing.
Does Harbor Stones offer cutouts for sinks, cooktops, or other elements?
Yes, like most professional contractors in the market, Harbor Stones 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 Harbor Stones provide for its work?
According to our information and industry practice, Harbor Stones, 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 Harbor Stones in any convenient way on this page to get the current terms.
