Fresh Pond! Mark came out and cleaned our pond, took out all kinds of hunk, and now we can actually 👀 SEE the fish! It’s so beautiful, the fish are having parties every day! He accomplished it under 2 hours and at an extremely reasonable rate. Mark is also a very nice guy.

Great expertise on all things koi and mechanical Mark is outstanding. He is the go to expert on fish health, water quality, and keeping pond systems (pump, filter, UV, lights, etc.) working efficiently. My water is crystal clear and my fish are beautiful. He is also a master at detecting and repairing cement pond leaks. Thank you Mark!!

Pump Replacment My experience with Koi Depot of San Diego/Inland Empire was excellent. I needed a pump replaced for a waterfall and pond. This was a small project, however there was an urgency to complete the project within a week. Mark Lawson met with me after hours to go over the job and found a way to fit it into their schedule. I am very satisfied with the work performed by Koi Depot of San Diego/Inland Empire and will gladly use them in the future.

Pond Cleanout Mark was tremendous to work with. He communicated extremely well initially through Thumbtack, and then through texts and calls (with our permission). He was punctual, thorough, and trustworthy. He asked good questions to determine our wants and needs as it related to our pond, and then provided thoughtful guidance based on his decades of experience in this field. He also didn't try to upsell us or convince us we needed products and services that we didn't really need. In fact, he offered us a kind of tiered solution approach, installing a product that he designed personally, with the option to add another in the future if needed. Mark also went above and beyond in helping to decorate our pond, sourcing plants from a nearby seller and even picking them up an installing them himself. I can't recommend Mark enough, and will absolutely use him in the future for all my pond-related needs.

Water Feature Repair and Maintenance Mark is very friendly and knowledgeable. He was very generous with his time, answered all of my questions and provided me with a wealth of information that will help me to insure against future catastrophic events, when I'm ready to add new fish to my pond.

Great "Good hearted and honest man"

Fantastic Job for a Very Fair Price! "My very dirty pond was cleaned to appear brand new. All of the pond scum and overgrown plants were thinned or removed, the waterfall and rocks were power washed and the autofill system was replaced since the parts were beyond repair. The extremely fair price for the job was the "frosting on the cake". I will definitely use them again."
Frank S.
Mark at Koi Depot "Mark from Koi Depot of San Diego did a wonderful job repairing my waterfall / pond leaks ! It was great doing business with him . He is familiar with all the aspects of the workings and operation of a typical pond and waterfall . His repair quote was more than fair and though he came back within a day or two to take care of a very minor (unforeseen) leak , there was no extra charges !! He also emailed an appointment reminder , which is refreshing , considering the way some contractors treat customers these days !! He is a very pleasant and down to earth person to deal with . I highly recommend Mark for any pond or waterfall repairs. You'll be glad you did .

Pond Repair done right "Mark was courteous and competed the work professionally."

Prompt and service delivered as stated "Awesome job. Cleaned a few other easy things with a power washer free of charge."
Gunnar M.
Pond/waterfall improvement "Mark analyzed my pond and waterfall for potential leaks, and the need for a filter system and a better chlorine and pH control program. He was able to start and complete his work within two days from the initial consult, cleaning out the pond and stream, sealing some cracks, and hooking up a filter. He also explained maintenance and chemical testing and control of the water, and included a test kit. I'm sure this will greatly improve the quality of the water in the stream and pond. I've been very happy with his work."

Amazing Mark has made me fall in love with my pond. We pretty much inherited our Koi pond with no instructions; when we purchased our home and there was already so much muck in the top portion of our pond. Mark responded quick to my online consult form and came out to look at my pond in 2 days. He was polite and very knowledgeable showing me things about my pond My husband and I never even knew. The next day he came to service the pond while we were at work so I didn't have to stress about taking time off. My pond flows way better and the way he positioned the rocks; it looks like a way better then before; my whole yard looks better!! I will definitely be calling Mark for future work. Great customer service, quick, accommodating, great prices
Michelle M.
Pump "Mark was great!!! Instead of replacing the whole pump which would have cost me more money, Mark took the pump from my waterfall apart and only replace a small broken parts and save me some money. Just like many other reviews before mine. They have said it all. Mark was prompt, courteous, professional and reliable. He exceeded my expectation. I will use Mark again in the future when time to replace the other old pump. I definitely recommend Mark. You won't be sorry."

Urn-type Fountain We have a small outdoor, urn-type fountain which needed to have the motor replaced. Mark came out and took a look at the fountain, emailed an estimate within a few days, and we set up a time for him to come. He came out, did the job quickly and we paid exactly what the estimate was. We appreciated his work and attitude and would recommend him.
Tom C
Excellent Service I highly recommend Koi Depot to anyone. They fixed my outdoor water fountain efficiently and at a reasonable price. They did everything they said. Very good to work with. I'd work with them again.

Crack Repairs "We needed to have the cracks in a 40 year old 1500 gallon concrete koi pond repaired and also have the pond made deeper. We needed the job done very speedily as the pond was losing water fast and putting our fish at real risk. Mark and his assistant came promptly to inspect, gave us a very good quote and was able to quickly schedule the work on a date to suit us. They came on time and did the work efficiently, carefully and to our complete satisfaction. The disturbance to the koi was minimal. The pond is no longer leaking and looks 100% better with the walls increased in height. I would definitely use Mark again anytime for pond work with complete confidence.

Fountain Mark cleaned my fountain and moved the scrubs away as promised. I plan to use him again--mine was not a huge job, but the rock fountain on top of the basin can't be moved so Mark sucked out all of the basin and replaced with clean water.
Pamela F.
Fountain Koi Depot was great! They fixed our water fountain and cleaned out the water filter in no time at all. Very nice and personable. I would recommend them highly for your project!
Bridget Capraro
I've been using Koi Depot for the past 8 years I've been using Koi Depot for the past 8 years. They do great work and have high quality equipment. My pump is so quiet, I really love it. Mark is very personable, creative and really listens to what your needs are.

Pond knowledge Mark is so helpful to me in his pond knowledge.  I have great admiration for him and his business.  I think if you are deciding whether to use him for your water feature...you'd be silly not to!

Valuable assistance if you're a pond owner Mark came to my house to rescue me from a pond leak puzzle that he solved. I appreciate that afterwards I had some follow up questions via the phone that he generously took time to discuss in detail. This man is "the Pond King"
Ron L.
Great service in Santee! Great service! We just got the new house and needed help in understanding the pond that came with it. They were booked out over 2 weeks, but the owner came over in the evening and walked us through it. Gave some great idea's and gave us information on local Koi club.

Shirley W.
Best in San Diego Mark is extremely knowledgable. His rates are very reasonable and in a crisis he is there pronto. It doesn't get any better. He is the only one to call in this area. He fixes messes that others leave you with. So call him first and avoid the headache and added cost
A. Fechner
Koi Service Mark has taken care of my Koi pond for over 5 years now. Both his big service (emptying the pond, cleaning filters, thinning plants, removing dirt from rocks etc.) and the small service (cleaning filters, trimming plants) are done thorougly and efficiently. His knowledge of Koi and ponds has been very helpful to me and his friendly and accomodating personality makes pond service a pleasure!
Shirley W.
Used his services for about 5 years now
12/13/2012

Mark is complex!  I have known and used his services for about 5 years now, after being jacked around over and over by others in this business and left with a disaster of a pond and very sick fish, and a ton of money down the drain.  We don't always agree, but Mark knows Koi and ponds and sources like no other.  He is a likable guy and has vast experience in all aspects of this hobby.  He does not charge an arm and a leg like all the others.  He tries to save you money. 
When you have sick Koi and no one, and I mean no one including our local vets, and our local Koi club will give you the time of day, he will come running.  He may not be perfect, as some others have pointed out,  but he knows his stuff like very few others, and he is there when you desperately need him.  His prices are more than reasonable and really, what else do you want? 

Bridget Capraro
My Pond Just because I belong to the Koi Club, doesn't mean I know about pond plumbing. Thank goodness for KDSD. They're super! They constructed my pond for me and gave me a lot of cost saving ideas. I can dig a hole and I clean fish poop, but when it comes to plumbing, I'll always call them. My pond runs beautifully and my Artesian Pump is so quiet. Only 1 washer has needed changing in the past 6 years. I just moved this summer and had to build a "new" pond. Thanks to KDSD we were able to transfer all the equipment, keeping the cost down.

The Best If you want to hire someone you can trust. KDSD Koi Depot of San Diego is the place. Mark is fair, honest and reliable. Believe me we called several people to help us with our pond and Mark was the only one that was able & willing to help us. I am very glad we found him.
Otto Dobre
Excellent service for my pond Mark is a professional. He's been doing a great job with my pond for the last 5 or so years. One time my pump stopped working on a Sunday afternoon. I left him a message in the hope that he'll respond first thing Monday morning. To my suprise, he called me back later that Sunday, then he stopped by and fixed the pump. So, yes I highly recemmend his services. Thanks, Otto
Teri S
Pleased in Point Loma Mark really knows water chemistry, pond equipment, and koi health. He fixed a leak in my pond which vexed many other pond services. I have always found him extremely dependable and reasonably priced. I will continue to use him for regular maintenance, equipment upgrades, and whenever strange problems arise.

Semi retired designer/filmmaker Mark (KDSD) has made my life so much easier and rewarding , he is a genius in solving pond problems and other building choices, and a very nice person.

The best of them all... Mark Lawson is the professional-when you have tried the rest (and please believe I have done so-I am amazed one of them is still in business considering the caliber of work they do)Anyway, when all is said and done there is no one like Mark Lawson and KDSD-experienced,patient, fair and always the best...what more can I say but do yourself a favor and call-don't even try the others-I have...
Richard W
Thank you! Have had other pond services out to work on my pond in the past. Koi Depot I have to say has surpassed all the rest! Pond looks great thank you!
Rebecca T
Great Service We just bought house that had a Koi pond, we needed help in understanding the whole system. Mark was great in taking the time to walk us through the system. Well worth the consultation fee....went above and beyond helping us!

Superior to others in the same field The work done by Mark of Koi Depot of SD is superior to others in the same field.  I've tried three other business and Koi Depot is the best. They do not gouge you with miscellaneous fees like others.  I've had emergency work done on a holiday and there was no extra charge.   Marks is always willing to work with you to get both the wife approval factor and still stay within budget--not an easy task given the costly nature of anything pond related. He will do what it takes to get your pond working and keep your koi safe.

Outstandingly Great Outstandingly great! KDSD kept in touch as I added to my order before it was shipped. The order was shipped on a Thursday as promised, and arrived Saturday morning. I was very happy. Highly recommended.
Jason Rivers
Long-time customer of Koi Depot I have been a long-time customer of Koi Depot, and have always received the attention I required, and my orders. I would like to thank Mark for the tireless hours he has spent helping us get our filtration system up and running just fine. Your service after the sale was great, and I can honestly say that we have absolutely no problems with our pond filtration what so ever.

Again thanks, always a pleasure...
