 Trustindex verifies that the original source of the review is Google. I had an exceptional experience with AAA Stone Age, and I couldn’t be more pleased with the results. They recently replaced the deteriorating tile around my spa spillover—an issue that had been a constant frustration since I purchased my home four years ago. While I initially considered tackling the project myself, I quickly realized that the level of precision and craftsmanship required was beyond my abilities. From the start, the team at AAA Stone Age demonstrated professionalism, expertise, and a genuine commitment to quality. Anastasia was prompt, informative, and incredibly courteous throughout all of our communications, making the process smooth and stress-free. Konstantin brought a high level of technical knowledge and attention to detail, particularly with the complex templating needed for the custom cap stones. The installer—whose name I unfortunately didn’t catch—was a true artisan. His meticulous workmanship and eye for detail brought the entire project to life beautifully. I’m thoroughly impressed by the skill, care, and customer service exhibited by everyone involved. I’m already looking forward to working with AAA Stone Age again on some upcoming EIFS/stucco repairs later this year. Thank you once again for an outstanding job!

 Trustindex verifies that the original source of the review is Google. Thank you for the fabulous stonework done by Andrew.  We've had severe peeling of our foundations causing us a heartache of scraping, priming and constant painting.  Now AAA Stone Age came and solved our 30 yr persistent problem.  It looks amazing.  We got the idea from a previous neighbor's home which we contacted and she gave us the referral.  She loved the pictures we sent her and she also told us about the conscientious work and expertise of AAA Stone Age that was done for her in in 2017, on her previous home.  Everyone made this experience easy from estimates thru installation thru payment.  I would very highly recommend this company and give them 100 out of 100!

 Trustindex verifies that the original source of the review is Google. AAA Stone Age did a fabulous job for me in refacing a small fireplace in our study. I needed it done on short notice and needed to find someone that could do the job and called AAA on a Saturday and they were there Monday morning. Not the norm I’m sure, but certainly we’re very accommodating to my situation. Alex did a great job was precise and attentive to detail in his work and I couldn’t have been more pleased with the outcome. I will be calling them again to do another project at some point in the future of a much larger fireplace.

Frequently Asked Questions

Q: How long does a typical stone veneer installation take?

A: Most residential veneer projects (1,500–2,000 sq ft) finish in 3–5 business days, weather permitting. Smaller accent walls or fireplace surrounds can complete in 1–2 days.

Patios & Walkways: Sweep or rinse periodically. Reseal joints every 2–3 years to prevent weed growth.
Facades & Fireplaces: Inspect mortar joints annually; tuckpoint as needed. Clean with mild detergent and soft brush to remove surface grime.

Q: Can you match existing stone if I only need a repair?

A: Yes—we maintain relationships with local quarries and salvage yards to source matching stone. If the original is unavailable, we blend similar shades and textures to achieve a seamless look.

Q: Is stone masonry more expensive than brick or vinyl siding?

A: Stone typically has higher material and labor costs upfront, but it offers unparalleled longevity, minimal maintenance, and significant aesthetic value, resulting in a strong long-term ROI.
