We hired Samir to replace our existing kitchen sink with a larger one. The granite counter had to be cut on all sides to support the new sink. Samir and team also handled redoing the plumbing, including installing a new faucet and garbage disposal. The whole process took only a few hours. Reasonable price, good communication, and quality result. Would definitely hire Samir again.

Okay. I just want to say that it's really hard to find good, honest service these days, but I think I just found it with Complex Granite & Marble. I called Samir for an estimate to repair some major etching on a polished marble table I thought was going to require a major fix. He responded immediately and came out the following day. He took a look at the table, determined it was an easy fix and went right to work. The table is back to looking beautiful and it was all done for free!!! And this was from someone who drove all the way out from Kent to Sammamish!!! How about that? Needless to say, I'd highly recommend Complex Granite & Marble for your next job.

Samir and his team did an amazing job with the installation and were instrumental in getting the countertops installed on Sunday so we could keep the schedule for the remaining steps of the process to have the kitchen remodel finished. They did an excellent job of installing our new countertops, removal, and post cleanup as well. I will definitely recommend them without any hesitation. They are totally worth the price quoted.

We had such a great experience with this company! Sam is meticulous! I am a perfectionist… so I really appreciate his attention to detail. He is the best price around, but either way that no corners are being skipped. We own several investment properties but this was for our own home and now every time we need anything for countertops we are only going to Sam. Customers for life!

Does Complex Granite & Marble offer cutouts for sinks, cooktops, or other elements?
Yes, like most professional contractors in the market, Complex Granite & Marble 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 Complex Granite & Marble provide for its work?
According to our information and industry practice, Complex Granite & Marble, 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 Complex Granite & Marble in any convenient way on this page to get the current terms.
