Granite & Quartz Countertops · Portsmouth, Ohio
Stone Surfaces
Crafted Locally.
Installed Right.
You don't have to drive to Columbus for quality stone countertops. Portsmouth Monument Co. is the only Cambria Certified Installer and Retailer in the greater Scioto area — with granite, quartz, and quartzite fabricated in-house and installed by our own craftsmen since 1914.
Quality Stone Countertops — Right Here in Scioto County
For years, homeowners in Portsmouth and Scioto County assumed they had to drive to Columbus, Lexington, or Cincinnati to get premium granite or quartz countertops. That assumption costs time, creates coordination headaches, and often means your installation is handled by someone who's never even seen your kitchen.
Portsmouth Monument Co. changes that. We fabricate and install everything locally — in our Portsmouth shop, by our own team — at the same caliber you'd find anywhere in the state.
Driving hours for a quote Big-city stone shops require multiple trips for consultation, measurement, approval, and installation. We handle it all from one local location.
Out-of-town installers who don't know your home Contractors sent from distant fabrication shops often rush the job. Our craftsmen measured your space — they know every dimension before they arrive.
Warranty risk from uncertified installation Cambria's lifetime warranty requires certified installation. Using an uncertified installer can void it entirely. We're the only certified option in this area.
"The kitchen you've been picturing — measured precisely, fabricated locally, and installed by people who've been working stone in Portsmouth for over a century."

Cambria is family-owned and manufactured in the United States — one of the only domestic quartz surface producers. You're getting a domestic product with rigorous standards, not an import.
Full Lifetime Warranty
Cambria backs its products with a full lifetime warranty — but only when installed by a certified installer. Our certification means your investment is protected by the manufacturer, not just our word.

Three Premium Surfaces.
One Local Source.
We offer three distinct stone types — each with its own character, durability profile, and price range. Our team will help you choose the right material for your project, lifestyle, and budget.
Granite
A natural stone quarried from the earth — no two slabs are identical. Granite offers lasting durability, heat resistance, and a genuinely unique character in every kitchen.
- Natural stone — each slab is one-of-a-kind
- Extremely durable and heat resistant
- Wide range of colors and patterns
- Requires periodic sealing for best longevity
Cambria Certified
Cambria Quartz
Engineered quartz with the look of natural stone and the advantage of non-porous performance. Backed by a full lifetime warranty when installed by a certified installer — that's us.
- Non-porous — never needs sealing
- Full lifetime warranty (certified installation required)
- Hundreds of colors and designs available
- American-made, family-owned brand
Quartzite
A natural metamorphic stone prized for its elegant marble-like veining without marble's high maintenance demands. Quartzite delivers a premium, luminous look for upscale kitchens and baths.
- Natural stone with dramatic veining patterns
- Harder and more durable than marble
- Lower maintenance than traditional marble
- Premium option for distinctive design

From Your Kitchen to Your Kitchen.
Four Steps. No Surprises.
We don't quote countertops over the phone — because we won't give you a number that isn't accurate. Here's exactly how our process works.
Call or Visit
Start by calling us at (740) 353-4055 or visiting our showroom at 1617 Offnere St. We'll discuss your project, show you material samples, and schedule a measurement appointment.
Laser Measurement
We visit your home and measure your space using laser measurement technology. Every dimension is captured precisely — no guesswork, no "we'll figure it out when we get there."
Design & Quote
With accurate measurements in hand, we provide a detailed quote and create a design layout. You review and approve everything before we cut a single stone. No surprises at installation.
Fabricate & Install
We fabricate your countertops in our Portsmouth shop, then our team installs them in your home. Same craftsmen, start to finish — not a subcontractor seeing your kitchen for the first time.
Ready to Schedule Your Measurement?
Laser measurement is the first step — and there's no obligation until you approve the quote.
The Only Certified Cambria Installer in the Region — and We've Been Here Since 1914

From the Families
Whose Kitchens We've Transformed
"We had our kitchen countertops replaced with Cambria quartz and the result is stunning. The team measured everything precisely, fabricated locally, and installed without a single issue. Knowing they're the only certified Cambria installer in our area made the decision easy."
Wheelersburg, OH
"I was tired of driving to Columbus every time I needed stone work done. Couldn't believe quality like this was right here in Portsmouth. The team measured our bathroom, fabricated exactly what we discussed, and the installation was clean and professional."
Portsmouth, OH
"They came out to measure, gave us an honest quote, and showed us granite options in person at their showroom. When installation day came, it was the same people who measured. They knew every inch of our kitchen. The stone fits like it was grown there."

Answers Before You Ask
The questions we hear most from countertop customers — answered plainly.
Can I get a countertop quote over the phone or by email?
We don't provide countertop quotes over the phone — and here's why: countertops are cut to the exact measurements of your space. Quoting without measuring risks errors that cost you time and money. All quotes begin with a laser measurement visit to your home at no obligation. Once we have accurate dimensions, we can give you a precise number you can actually count on.
What is a laser measurement and why is it necessary?
A laser measurement is a precision digital measurement of your kitchen, bathroom, or shower space. We use it to capture every dimension — including angles, cutouts for sinks and appliances, and any irregular features — before fabricating your stone. This means the countertops we cut in our shop will fit your space perfectly when our team arrives to install.
What makes Cambria different from other quartz brands?
Cambria is American-made and family-owned — one of the only domestic quartz producers. It offers an extensive design range, a non-porous surface that never needs sealing, and a full lifetime warranty. That warranty is backed only when installed by a Cambria Certified Installer. We are the only certified installer and retailer in the greater Scioto area, which means we're the only local option where that warranty applies.
How long does countertop installation typically take?
Most countertop installations are completed in a single day. The timeline from your initial call to completed installation depends on the scope of your project and our current schedule — we'll give you a clear timeline during your measurement appointment. Because we fabricate in our Portsmouth shop, we have direct control over the production schedule.
Which stone is best for my kitchen — granite, quartz, or quartzite?
It depends on your lifestyle and aesthetic preferences. Cambria quartz is non-porous, never needs sealing, and is ideal for busy kitchens — plus it carries a lifetime warranty. Granite is a natural stone with unique character in every slab, is extremely durable, and requires periodic sealing. Quartzite is a premium natural stone with marble-like beauty and more durability than true marble. When you visit our showroom, we'll walk you through all three with real samples.
Do you also install countertops in bathrooms and showers?
Yes — we fabricate and install stone surfaces for kitchen countertops, bathroom vanity tops (with custom sink cutouts), and shower surrounds. The same precision measurement and in-house fabrication process applies to all three. Call us to discuss your specific project.
What areas do you serve for countertop installation?
We serve Portsmouth and the surrounding communities throughout Scioto, Pike, Lawrence, and Adams counties in southern Ohio, as well as parts of northern Kentucky including Ashland, South Shore, Vanceburg, and Greenup. Not sure if we serve your area? Call us at (740) 353-4055 and we'll confirm.
What forms of payment do you accept?
We accept cash, Visa, Mastercard, American Express, Discover, personal check, and invoice. Full payment is required prior to installation.
