Tim Lee has gone so far above and beyond; he is extraordinary.  I highly recommend this excellent company.

Our travertine floors were showing their age. Tim did an excellent job on 2 baths and 4 rooms. They are beautiful. He suggested grinding a shower floor to a rougher finish so we could do away with a shower mat. His idea has been very effective. He knows his stuff.

I am giving North Bay Restoration a 5-star review and I haven't even officially hired them yet! I contacted Tim about a brand-new limestone floor that was installed in my bathrooms both wet and dry areas. The wet areas were growing black mold after just a couple months. The contractor told me was because sandblasted limestone is not suitable for showers. I called Tim to restore these areas and in the course of our lengthy conversations and review of photos, Tim concluded that this was an installation issue not a limestone material choice problem or superficial topical issue. He pointed me to the only forensic tile expert in all of NoCal who came and determined that indeed the shower pan was not sloped properly and the weep holes not protected, thus trapping water in the mortar bed. My contractor fixed the issue only after experts were able to convince him it was his fault. Never would have happened without Tim's expertise and referral (all given freely). Now I find that the dry areas of the limestone that have shown dirt from day one is also an installation issue thanks to Tim's expertise again! Grout haze was spread on limestone before it was sealed and now that grout haze over time is producing "picture framing" dirt patterns. Again, I would never have known this if not for Tim. Again, Tim spent hours on phone with me and reviewed situation in depth with photos, etc. All without his ever being hired. All very promptly and compassionately. He has also given me tons of advice on how to fix the issue and how to maintain the floors going forward. Amazing!

We had an issue with some tile in our shower after a cleaning company sprayed it with a solution that caused it to discolor. Tim Lee was great. He returned messages and phone calls promptly, gave great customer service and was very knowledgeable and professional. I highly recommend his services. He will walk you through the process, answer any questions you have, and talk to you about how to keep your tile/stone looking great for years to come.

Called yesterday for damage done to marble countertop in master bath. Left a rag soaked with cleanser on top of countertop all night. Etched it. North bay came out today and it looks like new. They also got rid of all the deposits from shower looks fantastic as well. Could not be happier. Will definitely use again.

John R. San Francisco, CA


The stone at the entry to our home was very dirty and scratched. Tim did a great job cleaning the stone, buffing out the scratches and applying an enhancer/sealer. It looks terrific now and the most obvious scratches are no longer visible. I would definitely recommend Tim for any stone work you have.



I had some issues with cement floor tiles laid down by another contractor. Even though I was out of Tim's service area, it looked like he had relevant experience to speak to the issue and the possible fixes. Tim offers free consulting so I reached out for a neutral, unbiased assessment of my flooring situation. I uploaded several pictures through Tim's consulting portal and he promptly responded the next day. We discussed possible causes and solutions and Tim provided contact info for a couple of contractors in my area with specific experience dealing with cement floor tiles. All in all, a very positive experience. Service: Tile work replacement.



Clear, friendly, expert help provided efficiently.

Doug F. San Francisco, CA


Though we elected to go a different route with new tile (instead of restoring the existing floors), I just had to give Tim high marks for his responsiveness, follow-through, and professionalism. I was particularly impressed with Tim's knowledge about treatment as he helped get us to a place where we could make an informed decision.

Glyneth S. Napa, CA


They were timely and kept the bathroom clean during the job. The grout was removed on the pan and up the walls. They were very careful not to chip or scratch the tiles. New grout matched original perfectly.  A job most tile setters will not do because it so tedious. My very large shower is like new! John and Glyneth

I had some problems with the tile in a home I recently purchased. I didn't know what to do about it so I reached out to Tim at North Bay Restoration. I am very glad I did. Tim was extremely knowledgeable and provided a lot of useful advice over the phone. He took his time explaining things and obviously put a lot of thought into my situation. He made a recommendation about an approach and didn't push me to make any drastic decisions which saved a lot of money, showing honesty and building trust that continued throughout the job. He and Marci were polite, helpful and reasonable in every conversation and email. Because I was away from the house, I had to rely on Tim's word that he would do what I requested without me being there- and he did, on budget and on schedule. The tile looks fantastic and there wasn't a trace of dust in the house- he and his team worked diligently and expertly just as he promised. Not only am I happy with his work and how the floor looks, I am very grateful to have worked with someone so true to his word that I could trust with something important to me. I feel like he went out of his way to help me, almost doing me a favor. I would trust him with any job and would work with him again without a moment's hesitation.

Claire S. Healdsburg, CA


We installed a large concrete patio area within the last two years and the color had just leached out of it. It also gave off a lot of dust. Tim recommended a sealing product that brought back some of the original color and completely took away all the dust. It's beautiful and feels clean underfoot! He did such a meticulous job ensuring to tape off any vertical surfaces and plants. He also recommended a cleaning specialist who did a great job prepping the site. Thank you so much Tim. We highly recommend you.

Lynne L. Belvedere Tiburon, CA


Tim was fantastic. He cleaned and sealed a huge quartzite kitchen (island and counters), 3 moderate bathrooms with marble countertops plus stone tub/showers, and in the master shower, white quartz counter tops, and a large walk-in shower. He was fast but thorough, very tidy and careful and cleaned up all his work surfaces as he progressed through the job. I highly recommend this company; I was very impressed with the service.

Michael M. Sonoma, CA


Tim took the time to give the best advice for a sealer for my limestone balcony. Cares about his customers and not simply focused on maximizing financial reward. Highly recommended.

Dee R. Providence, RI


Tim Lee is a true professional. His primary goal is to assist the homeowner in finding solutions. I would highly recommend him.

Indi Y. San Rafael, CA


Tim is a super well-organized person, and that saved me! I have a Jerusalem Gold countertop in the kitchen that got etched by lemon juice and baking soda. Years went by and my engineer for an unrelated roof project suggested Tim Lee. I contacted him, but then my roof project was about to start. Tim was patient and called me back four times over the course of two years until magically the timing was perfect! I was about to finally move back into my house. He refinished the counter and also did the bathroom counters (same type of stone) because he saw a few small blemishes. All fabulous now! I'll definitely rely on Tim for future projects, like the stone patio refurbishing after the stucco guys are finally finished throwing concrete at it. Hah.

Audrey S. Larkfield-Wikiup, CA


Tim was very helpful and his Customer Service outstanding! Him and Marci we're professional, quick, knowledgeable, and friendly. We needed our tile to be cleaned and sealed due to smoke damage and the entire process was painless and our floors never looked better! They were able to patch some dents - can't even locate them now! Thank you, Tim and Marci for a wonderful job!

Carolyn M. Lakeport, CA


I called North Bay Restoration (Tim Lee) to restore the grout on my tile floor. He did a beautiful job and also told me what products to use to keep it in perfect condition. I was pleased to see that he was careful to keep my home free of debris from the job he was working on. I felt that he was knowledgeable about the products that he was using and was professional and polite. I would be confident to call him again if I should need his services.

Tim Lee, owner of North Bay Restoration, and his wonderful assistant restored what was once a beautiful 600 sq ft. stone floor in my guest cottage. Over the years I had been advised to apply a sealant to protect the surface. I did so every couple of years. Unfortunately, the floor was no longer a welcoming sight. There were dark stains from coffee spills, olive oil and who knows what else. I could not clean the stains. I was so disappointed. Luckily, I found the North Bay Restoration website and after reading about Tim decided to call them. Tim came as promised after he finished a huge job he was doing. My job was so small I was glad he was willing to take it on.

Tim listened carefully to my concerns and gave me some options to consider. I decided I wanted the best I could get so the floor would be enjoyed for years to come. First, the floor was deeply and thoroughly cleaned- including carefully scratching off a spill of some kind of unsightly acidic liquid with a razor blade removing just the superficial layer of stone. That task alone took several hours for his assistant so as not to do damage. I had been sure the stone would need to be replaced which would mean a big project if I could even match the stone! I was not charged extra for the unexpected time to do this one task. Tim then coated a small corner piece of stone with several sealants and a urethane so I would see what the floor would like.

After the floor was thoroughly cleaned and left to dry Tim returned to apply a urethane on the floor. I decided on the urethane as I did not want any more staining. I wanted to be able to enjoy having people over and not need to worry about every spill!

I am so delighted with the outcome. I can enjoy my guests which have included children and big dogs. The stone is protected and looks great. I am so pleased that I found this company and highly recommend them.

I had hard water deposits (whitish cloudy areas) ruin an area of my dark granite countertop and I just let it go, 'cause I didn't know what to do.  A friend of mine said that the damage was superficial and only on the surface.  She said it could be repaired and recommended Tim Lee.  I waited months then finally got him here and he restored it perfectly, sealed 2 large areas and one small area of granite in my house, and found/filled a few cracks.  Everything is so smooth and like new now.  I hope nothing ever happens to the counters again, but if it does, I'll call Tim back.  He also told me how to maintain them and which cleaners were good, so I'm all set now!

Kathy W. San Francisco, CA


Tim and his wife came to my house in Marin to look at my limestone fireplace which had been damaged and was badly stained from smoke over a period of several years.  I was not hopeful that it could be restored.  They did a fabulous job and my fireplace looks beautiful.  They also explained how to protect the limestone and what products to use in the future. I found both Tim and his wife to be knowledgeable, friendly and efficient.  Their price was slightly below another estimate I received from a larger company.  I would definitely use their services again.



I had an appointment today for granite repair. Tim was on time (actually a few minutes early), explained process. He gave me a quote & stuck with it. I am very satisfied with the craftsmanship as he left me with a once again gorgeous granite counter top.

Tom M. Napa, CA


I called Tim of North Bay Restoration to caulk questionable grout joints after having two bathrooms remodeled by others. My schedule was immediate while Tim already had commitments. He suggested that I self-perform. I told him that my caulk work looked like I applied it with a mop. He then took the time to walk me through putting down two strips of painter’s tape before caulking. In addition, he helped me identify the stone type and pattern so I could source the correct sealer. Both the expert 'how to' and the stone identification via pictures were free gratis. I know who my next contractor will be!!!! Thanks, Tim



The owners are very helpful, knowledgeable, and professional. I recommend them for any of your tile and concrete flooring needs.

Shalimar V. Santa Rosa, CA


Absolutely the only people to call for marble refinishing. Tim and his wife brought my marble countertops, floor and shower from badly stained and damaged to pristine 'new' condition. Professional, courteous, on time, reasonably priced, and local.

Victor J. Sebastopol, CA


Wow excellent! The folks at North Bay Restoration showed up quickly, and did a great job with the entryway. The stone had become dull from years of heavy traffic. But they really brought back the luster, and the whole thing, looks like new. Plus, they told me the rest of the tile in the house did NOT have to be expensively cleaned and sealed, as other stone and tile people told me. Tim and Marci are honest and knowledgeable about restoring stone. Highly recommended.

Anita H. Santa Rosa, CA


I was referred to North Bay Restoration by a tile guy who was unable to take on the job at the time. The project was grout restoration in my tile shower.  I had the shower rebuilt after some extensive damage and the person who did the rebuilding really screwed up the grout work.  All of the existing grout needed to be removed, the tile cleaned and the entire area regrouted. I emailed photos of the work to be done, and after speaking to Tim on the phone, was quoted a price.  Several days later, Tim came to look at the project in person and we decided that the adjoining tub surround also needed to be done.

Tim and Marci did an excellent job. I took quite a bit longer than they had initially anticipated because of the messed-up job the previous guy did, but they persevered and did a great job.
I would highly recommend North Bay Restoration.

Harry W. Saint Helena, CA


My wife, Gayle, and I were fortunate to get a referral to North Bay Restoration to work on the tile floors and granite counter tops in our home and restore them to a beautiful and "like new" condition.

The project was completed over a three-day period. The owner, Tim Lee, and his wife Marci did an outstanding job… I can't say enough good things about how they handled the job; very professional.

We were so pleased with the results that several months later we contracted for another, smaller job with them. Again, they did an outstanding job. They restored our slate patio to a lovely condition and etched and sealed our tiled front porch.

Gayle and I have only the highest recommendation for North Bay Restoration and the work of Tim and Marci . . . good people doing a great job! Harry and Gayle Willett

Carolyn M. Kelseyville, CA


Tim Lee installed tile in my kitchen and bathroom. Tim did a fabulous job! He’s very professional, got the job done quickly, & it looks absolutely perfect! He left my home spotless! I would recommend Tim for any tile job.

Julee W. Ukiah, CA


Our floors look great; we get so many compliments, especially from people who know what they looked like before!

Bealey N. Sebastopol, CA


Tim & Marci went waaaaaay beyond the call of duty to restore my messed up bathroom grout! I'm absolutely shocked at how good it looks now. Never thought it possible to have such a beautiful bathroom for such a great price. Couldn't be happier with the service of North Bay Restoration!

Matthews LB.  Cotati, CA


We feel much safer knowing that our beautiful natural-stone investment is protected with superior products. By having Mr. Lee seal our stone professionally, we know the job is done right.

Davis C. Oakmont, CA


I highly recommend Tim Lee for stone restoration in Northern California..... Tim is personable and has the experience and proper equipment to do his work meticulously!

A.H. Santa Rosa, CA


Tim and Marci did an excellent job. It took quite a bit longer than they had initially anticipated because of the horrible job the previous guy did, but they persevered and did a great job…. I would highly recommend North Bay Restoration.

Davis D. Napa, CA


Our restoration was successful! Thank you for working with us to make the solution possible. It is refreshing to work with an honorable individual as yourself; who will rectify a material problem and reduce unneeded stress in a major renovation....I am glad to recommend your company as a fine stone resource for your business ethics.

Nancy Adams. Sonoma, CA


Tim Lee is definitely a master in his trade. Our bathroom was terribly etched & chemically burnt from using the wrong cleaners over the years. We tried everything possible to repair the damage ourselves. Tim made the job look easy. Good as new! Best yet, it’s properly sealed & we now know how to take care if it!

Pieri K. Santa Rosa, CA


My husband and I recently purchased a home and the master bathroom needed extensive tile and grout work. Tim did an excellent job- the bathroom looks new again! I would recommend Tim for all your tile work. Thanks again Tim for doing such a great job!

Beckwith J. Forestville, CA


If you're considering adding or maintaining stone in your environment, I urge you to contact North Bay Restoration.

John Helms. Petaluma, CA


We called several contractors before we found North Bay Restoration to grind smooth and polish our entry floors. Everyone we spoke with seemed reluctant to do the work. To our amazement, Tim Lee had all the equipment necessary to do the job quickly and at a fair price. We are very happy with the results and now recommend NBR to everyone who compliments our floors.

Larson P. San Rafael, CA


My downtown office front walkway was extremely slippery. I knew I had to do something fast when a client fell on a rainy day. Fearing a lawsuit, I called North Bay Restoration & Tim Lee came right out to give me an estimate; even agreed to do the work the following week. The dangerous slip issue was resolved quickly. What a relief!

Smity M. Mendocino County, CA


Concrete is such an incredible surface. You never know for sure exactly what it will look like when the color stained and finishes are applied. That's the beauty of it! We love our floors! They have a unique leather look to them. Everyone tells us they've never seen anything like our floors. To us, they're worth millions!

Paulson P.  Napa Valley, CA


Tim’s routine maintenance prices are very reasonable; he actually saves us money over the long term and definitely saves us the hassle. My house keepers absolutely love him!
