Cornerstone Home Surface Renewal

Just had my floors done and they look awesome!!! James you are the best! And such a killer deal. Thank you so much

5 stars across the board! James is one of the most professional people I’ve ever dealt with! Shows up early and stays until the job is PERFECT!!! This is the 3^rd time we’ve had him clean our stone /​tiles and carpet! Everything looks EXCELLENT!!!
A+++++++++++++++++++++++++++++++++++++++

They offer a deal on Unilocal and they don’t honor it. he just hung up on me when I asked him for the deal.

We had James come out again 18 months later, and again… Just. Beautiful. It looks like a brand new floor, I couldn’t be happier! Thanks James!

I am with BJ. James seems to be a nice guy. And I was hoping I would not have to write this review. The floor got mainly clean, except some corners that his big machine could not get (it would have been nice if he worked on those, too). But the problem was his machine broke the threshold between my tile floor and pergo floor. He agreed to get my handyman to fix it and he would pick up the cost. He never paid to this day, even though iIt ended up costing half as much as the original quote I gave him. He simply quit responding to my emails. I am quite disappointed.

Couldn’t even get a call back.

I called cornerstone about doing the bathrooms in my whole house and left a message on their voicemail a while after James called back and immediately you can sense his enthusiasm for what he does and very good customer service relations skill. He did 5 bathrooms for my house and even throw in the countertops in my laundry room. Overall wife is happy me happy we now have surfaces that’s non-​porous and also looks great. Being a veteran myself I know that attention to detail is always administered and James lived up to it. Call him now he’s always booked!

:-(I like James. He is a nice guy. I am so sad that I have to write this review. I hired James a couple of years ago to clean/​seal my limestone floors, walls, and counter tops. he did a so so job. So when I needed service again a few years later I decided to give him another shot. Limestone is a finicky and sensitive stone so I hired James again to hone, repair, remove etching and re seal. I am so sorry I did. He ended up sealing my stone with a product that actually damaged my limestone. It states clearly on the label «not for honed or polished limestone». So my stone is damaged not only with a great variance of sheen between dull and shiny, the stone crack he «repaired» is gone. The substance used wasn’t even adhered to the stones completely and came out the next day. Worse yet, I have sent several emails to him with no response. Price I paid for the job $ 950. Cost to strip and re do $ 1500-​$ 2500. And they are not even sure they can restore it! I am beyond disappointed. It is going to cost me double what he charged due to his inexperience. He took a beautiful custom honed surface and turned it into a sticky shiny disaster. Not to mention the grout haze left on my cabinets, and the sealer that covered my chrome faucets. You will not want to hire Cornerstone to care for specialty surfaces.

I’ve never written a review for a service that I did not receive. However, our experience just TRYING TO GET A QUOTE from Cornerstone was so bizarre and frustrating that we have to share it.
We sent an e-​mail describing our job and asking to arrange for a walk thru in our house. Nothing. So we left a voicemail with the same info. Nothing.
Called again and after a few days we got a response from a voicemail we left. From there, a couple of the workmen came to our house to look at our bathroom. They were late to the appointment (which we overlooked) but when they arrived they were efficient and professional. They left here promising that a quote would be on its way «shortly».
We waited. And waited. After a couple of weeks we sent another email as for the status of the quote. Nothing. So we called and left several voicemails. Again… nothing.
Waiting another week and another … rinse and repeat … finally someone called us in response to one of our e-​mails. To their defense, the person that called us seemed genuinely apologetic about dropping the ball and promised to get us a quote «by the end of the day».
Shockingly, since our first contact with Cornerstone in August, we never received a quote or an explanation as to why they ignored us.
As consumers we always strive first to target our local businesses and especially those «mom & pop» shops with artisan skills. However, Cornerstone demonstrated a complete lack of administrative competence and blatant disregard for a potential customer. If they didn’t want to do our job or couldn’t do our job they should have stated so. Unbelievable.

All our stone looks brand new now. James was easy to work with, and gave accurate written quotes for work. Price was a bit higher than some other quotes I received, but I think it was worth it.
James was attentive to my pickey needs as well. When I did not like the color of some caulk, he came back and changed it.
Well done cornerstone.

I am amazed at how great our floor looks. I made an appointment for my business about a week ago as it was a last minute tile chance for me and I was glad that they had an appointment within a couple days for an estimate. James got started on our floor the following day and I was impressed with the finished work. I asked a bunch of questions as I did not know exactly what color tint I wanted. We went from having a spanish tile floor to refinishing the concrete. It really added value to our location and I’m happy because I won’t be staring at the other tile all day when working. Hiring cornerstone was one of the best decisions I’ve made for our brick and mortar store. I’m adding a picture of the finished work.

James just stopped by to take care of my bathroom limestone or quartz countertop which was heavily stained by some previous tenants, including rust stains. To my surprise, the countertop looks good as new! I would definitely recommend James to anyone.

Cornerstone provided a true 5-​star customer experience for me and I utilized a whole bunch of the offered services.
I had a bit of a schedule crunch as I was trying to get a whole bunch of home improvement and maintenance projects done as a surprise for my wife when she returned from an overseas trip. This included some serious tile and grout cleaning/​sealing in our bathrooms and kitchen, full house carpet cleaning and cleaning and sealing of a lot of external aggregate concrete and slate for our driveway, patios and pathways.
I was seriously concerned that I might have a lot of trouble scheduling someone to get the work done in the short time I had available due to a mountain of other projects I was also completing at the same time.
I called James at Cornerstone and described my predicament and the schedule constraints and his first response was that it might be hard to get it all done on schedule due to other jobs… followed very quickly by a «let me check with my wife about doing it on Saturdays». Very quickly after, James called me back and gave the thumbs up. He (and his wife) literally made time on his weekends to get all these jobs done for me in my schedule. Best customer service ever. Great friendly guy to talk to as well.
For the first day of work, he showed up on time and got straight to work on cleaning and sealing the the internal tiles in the bathrooms, followed by the kitchen and then went straight on to cleaning all the carpets. I was very impressed with his attention to detail, thoroughness and quality of all his work.
The next weekend he again arrived on time and went right to power washing all of my external stone and concrete surfaces. Again he was thorough, efficient and did not rush any of the work. He recommended applying a base sealer and then a «wet look» sealer on our slate and aggregate. He went ahead and did this and the results were spectacular. All the surfaces now look great… better than the day we has it all installed over 10 years ago.
He only missed one small area of sealing on a seat wall and he immediately agreed to come and take care of it when notified. This clearly shows James’ commitment to after-​the-​fact customer service and satisfaction. The fact that I have been lazy in giving him a time window to actually come over and do it is my problem :-)
I cannot recommend Cornerstone Home Renewal highly enough. A professionally run, highly knowledgable, reliable and customer focused business run with a high level of integrity.

James is a real professional! Our bathroom marble floors look amazing. He took special care to work on areas that were damaged from an acid spill. He even offered to come back and put in a few more hours at no cost to do the best he possible could. He gave a reasonable quote too. Great service, we would not hesitate to call him again.
Thanks James!

One word… AMAZING!!! My marble looks brand new… I thought I was going to have to replace it…
I can now see my reflection in the marble tiles.
James did a wonderful job. He is very professional, friendly and really cares about his work…
I have already started passing out his name to all my real estate friends…
Thank you James…

James did a great job on our countertops in our kitchen and bathrooms. He gave us honest feedback, quoted us a reasonable price and the work exceeded our expectations. I highly recommend him.

James came out to clean my granite, travertine and marble and reseal everything. Looks as good as new and they were considerably less than their competition.

Only positive things to say about James as he went above and beyond my expectations. He did a great job on my old terrazzo type stairs in san francisco, but more importantly, he excelled in cleaning my shower. Even things we didn’t discuss prior to him coming out wasn’t an issue for James. He didn’t nickel and dime me for any extra work, he just wanted to make sure I was satisfied, which I was.
So after a few days of the initial visit, I had some calcium buildup in my shower. I called James and only in a matter of days he was back to fix the problem. And of course no extra charge.
James is also very knowledgeable when it comes to his scope of work, and was great at answering all of my questions/​concerns.
Thank you James.

James is such an expert at what he does. He refinished my granite counter tops and they look absolutely amazing. He is an absolute professional and offers impeccable service.
I have a long list of items that need to be done so I will definitely call him again!

We’ve been wanting to clean the our limestone entryway for years! With 2 kids, 2 dogs, and many parties over the past 10 years… it’s taken a beating. So when I saw the Groupon for Cornerstone, I took that as a sign.
James at Cornerstone was great to deal with. He is very professional and knowledgable. He gave me options: clean & seal… clean, resurface, seal… And he explained what he he was doing. I’m a happy camper!
My entryway looks bright and new! Ready for the next party!
