Koi Pond Services in Ashburn

Overall they did a good job, price was higher than estimated because they did not actually come out to see the pond first, just gave them pics on-line. Wish the estimate was closer. Turned out to be an extra $200. The guys who cleaned the pond were nice and quite knowledgeable.

This was not the first time I had used Harmony Ponds. I had used them several years ago, but was not happy with the quality of their work. However, they now have in their employ someone who is knowledgeable about koi ponds. He was very prompt both times he came to work on my pond. Although their prices are very high (they do alot of corporate work), at least you can count on them to do the work both timely and professionally.

Backyard Ponds of Beltsville, MD., installed my koi pond 2 years ago, replacing one that was horribly installed by another local landscaping company. They were quick, cleaned up when done and gave me an exceptional deal. I called them back this year to clean the pond. They emptied the pond, contained the fish and scrubbed it squeaky clean. No more dangling algae or dirty water. When I came home from work, it was crystal clear, the waterfall was adjusted for settling and the fish appeared healthy and happy. I would clearly recommend them to anyone interested in putting in a fish pond!!

This is the second time I have used Pond Doctor. The first was in the Spring, when I also had a leak in my Koi Pond (which consists of three separate ponds connected by waterfalls). Mark and his men came out and cleaned all three ponds, and fixed the leak, which was in the lower pond, in one day. Total cost was $1600. This time I had another leak, about 17 gal. per hour, and Mark's men came out, diagnosed the problem being in one of the waterfalls, and fixed that one. Cost for this one was $400. I can't speak to whether the cost was in line with others doing the same type of work, but it was well worth it for me. The work was done quickly, competently, and everything was cleaned up after. And no fish were lost. I strongly recommend Pond Doctor if you're having trouble with your pond, or just for Spring cleaning if that's all you need.

James, the owner, is one of the most responsive and responsible professionals in the landscaping business. I call Vista Pro Landscaping whenever my koi pond requires service. James installed my pond nearly ten years ago and helps me troubleshoot any problems I'm experiencing over the phone at no charge. He offered me his cellphone number and made me feel at liberty to call anytime I needed help or advice. As it stands, other than a yearly spring cleaning, I think I have needed Vista Pro Landscaping to come over and repair something only twice in the ten years I have had the pond. They cleaned the accumulated gunk out of the bottom of the filter and topped off the filter beads on one occasion and replaced some light fixtures and installed a new valve on another. The pond never worked better or looked cleaner! Vista Pro Landscaping takes professional and personal pride in its work and aims to please. I made the mistake of trying another company when I had a problem and they were unable to resolve it, despite repeated and unannounced visits to my backyard, for which they attempted to charge me every single time. Never again. Vista Pro is the way to go.

Arrived on time for the estimate appointment and the work (and clean up) were completed in two days. I wasn't at home but the neighbors commented on how hard the crew worked. And I liked the effect!

We were having flooding issues and decided to install a French drain. We got estimates from several companies and decided to go with Xtra Care because we liked their ideas and found their prices to be very competitive and reasonable. We liked that we could get waterproofing, drainage, and lawn services all from one company. We also liked Cleber and felt he understands customer service. His crew worked very hard and in less than two weeks waterproofed the foundation along one side of our house, dug a French Drain, built up our window well wall, and re-leveled a patio. We later hired them to do yard clean-up and to dig an area for me to have a vegetable garden. We also had them draw up a plan to add a fountain to our Koi pond. We like the design very much and are saving up for that as a future project. In a project as big as ours, there are bound to be surprises or hiccups-- like when when we discovered a major tree route blocking the planned path of the French drain. Cleber's team was careful to consult with us on a solution that we all agreed on before proceeding ahead. Or when we decided not to do lawn re-seeding but the message failed to get back to the crew and they did it anyway, Cleber did not charge us for the mistake. In short, we feel Cleber runs a professional business and is eager to do a good job. He and his team are very responsive and understand customer service. It's been very easy to work with his team.

The property is located pretty far away from Michael, but he was one of the only landscapers who was responsive during this busy time of year...thank you! He gave me a couple recommendations of local companies that might have been cheaper which I appreciated, but none were available on the short time frame i was looking for. Michael had to re-schedule the start of the work because of a conflict with his schedule, but he was good about calling me early and letting me know. Michael was good about getting the job finished very quickly (in 1 day and another early morning) and was friendly and pleasant to work with. The back yard looks great and he warrantied the work for 1 year from any unexpected sinking of the soil. His specialty is in dealing with Ponds and it sounded like he had a lot of experience although I was having him remove one rather than install it.

It was/is an awful experience. It started out that the maintenance personnel sent out (two of them) stopped in the middle of work and advised that their hose to drain the pond was broken, and they needed to have it replaced before proceeding. They claimed they would be back the next day. Fair enough, these things happened. After repeated phone calls I finally had them return about 9 days later. The worst came after their work, as they probably punctured the rubber lining of our pond during the maintenance. We are losing literally 50 gallons of water per day, and Harmony Ponds still has not responded to my calls. I would use someone else right away, but I'm still hoping they have enough of a sense of professionalism to come back out and check our pond.

We had a great experience with Jesse and Tillerman Gardens. We loved the pavers he put in and the choices we had to choose from. Everything was done very quickly and the quality was superb. Almost a year on and everything still looks amazing. It vastly improved both the look and functionality of our yard, which was difficult to get around in/enjoy prior to the landscaping being done. We will probably be having Jesse back in the near future to do a koi pond as well.

Two employees arrived on time, were careful with our fish and respectful of our property. They did an excellent job cleaning the pond liner and making minor repairs. They completed the work in a reasonable amount of time. My lone suggested improvement is that they provide a couple of days notice on when they will perform the work.

We had three projects. It started out with just hard cleanup, but they were so good that we extended the first contract to include tearing down an extension to a stand alone garage. Then they worked on our deck - replacing rotted boards, resurfacing and sealing all three levels. Great job, so we asked them to rebuild a large old greenhouse that was unusuable. Fantastic job!! We just set it up for planting for spring now - first time we've used it in 10 years. That went so well that we asked them to address some foundation waterproofing issues, pour a new cement slab and install a new greenhouse kit that we bought from Home Depot. We're already enjoying it. What I really liked about this company is that they think things through before they start working; when they encounter problems, they discuss them with you; and they don't give up when they hit a snag. Just trying to save money so I can hire them back for more projects in the spring. Their prices are very reasonable for the high quality of work they perform.

Same-Day Service Saved the Day! Thank goodness for Bjorn Neumann, owner of Heidelberg Fountains and Ponds! The Rotational Ball Output part, a very key part, on my Aquascape pond pump broke the day after I had cleaned it. As such, the pump could no longer send water to the pond filter. I was worried about the impact on my numerous koi before the weekend. I contacted Bjorn this morning and asked if he could work me into his schedule today. He squeezed in this urgent repair and provided same-day service. More importantly, he was familiar with the pump, a good one, and knew the weakness of this particular connection. So, he provided a superior, more durable, replacement part that will allow me easy access to the pond pump for future cleaning. He also checked my waterfall pump’s connection and functioning while he was here. Great service, as always! I will hire him again for pond cleaning and/or repairs. Previous Review (3/6/2019) I highly recommend Heidelberg Fountains and Ponds owned by Bjorn Neumann who worked at Merrifield for 15 years before starting his own small business. I have been using his services for three years after trying many others. Bjorn offers reasonable rates and outstanding customer service. He just finished my pond’s spring cleaning and took good care of my koi and goldfish during the whole process. Most importantly, I always learn something new from him whether it is about my fish, the pond filter, tips on pond care or better aerators. He can be reached by text or phone at (703) 350-6237.

Bjorn Neumann has serviced my koi pond two years in a row. I have used other companies in the area, and he is by far the best! In addition to doing the cleaning, he reworked the water pump positions and piping to improve water circulation and make the pumps easier to access and clean. The parts that he used are much stronger than what I had. Bjorn recommended some pond care products that were new to me. I really like the barley pellets over certain chemicals or mini barley bales. I have learned new things from him on each visit. Other companies do not want to teach you how to care for your pond better. I highly recommend him based on his expertise, quality workmanship and his reasonable prices.

They did a wonderful job and were equally wonderful to work with. They arrived on time and finished the job in 2.5 days and charged us the exact amount of the estimate. The workmanship on the stone walls installed in the swale area to handle the erosion problem was excellent. The landscape design was perfect for our needs (natural, native plantings). The work was done in the Fall and we are just now seeing the effect of the beautiful sod and new spring flowers. We are already thinking about the next project we can hire them to do.

I had used Sean before to do repairs on my koi pond, but the last two times (once late last fall) I made arrangements to have him do repairs he has never appeared. This last time I needed him to remove a malfunctioning pump and replace with one I had recently repaired...a very small job. When I spoke with him, after leaving several messages, he said he was starting a new job but would try to stop by on the following week. I never heard from him, and since the pump was sounding much worse, I called another firm, who responded the following day. I think Sean does not have the capacity to do repairs, unless it is in between pond building jobs.

I contacted Sean and he came to my house on a Sunday afternoon to look at the koi pond. We talked about how he could install the ledges and then he told me what else he could do to just make the whole thing a lot nicer. He called me with a bid a few days later. He started on the day he said he would. He was very efficient. The work place was kept clean and then everything was cleared away cleaned up afterwards. The pond is inside the yard that is fenced for my dogs and he was conscientious about keeping the gate closed. He had great design ideas and really improved the look of the pond without it costing me any more. The project cost exactly what he said it would. One part of the back wash piping was misdirected and he came back and fixed that the day after I called him. Months later the bulb on the UV filter had gone out and he came right out and replaced it. Sean always answers his phone or returns the call in a few hours. He is the most pleasant person to work with, extremely sincere and decent. All in all, a great experience.

These guys did a fantastic job for me. Matt and Noah (the owner's brother and son, respectively, I believe) were incredibly careful and thorough. They got the fish out, patiently mucked out the muck, pressure-washed the stones and sides. They replaced the filtration medium and patiently re-positioned the plants, air-stones, and lights according to my nitpicking instructions. They were beyond patient with me: at one point, I asked if the muck from the pond smelled bad. They said "no", so I said, "good, how about scattering it around the roots of my roses?". And they did. They also erected the pyramid-net that sits over the pond to keep out leaves and herons in the fall in winter. The next day, the pond was crystal clear and the fish were swimming around energetically -- even trying to spawn, I think! I could not be more pleased with the job Matt and Noah did. The cost was a bit pricey, including the $120 for travel time. Because of that, I will probably do the spring start-up myself. But I think Knee Deep will be my go-to guys for fall pond maintenance from now on.

First, the entire experience was positive. I started with a blank canvas and the water garden and patio with swing turned out more beautiful than I ever imagined. The stonemasons were very professional and courteous and kept the work area immaculate throughout the entire process. While this work was performed close to nine months ago, it is because of a recent experience that I feel more compelled than ever to provide a rating. I’m a firm believer in seeking the knowledge and lessons learned from reviews such as these on Angie’s List; however, I’m one of those folks that gets distracted and forgets to add a rating. Last weekend I did the “spring” clean on the pond and since the pump was off for a while, it did not start up immediately and I panicked [my two koi and four goldfish have become family!]. I called Maxsell’s number and wasn’t surprised as it was Sunday that I didn’t get an answer. I didn’t leave a message, however, within minutes Mike Dowling, the owner was calling me back! He was at my house within 15 minutes. Luckily, as Mike explained, the pump was simply not primed since it had been turned off for a while and all ended well. While Mike was there, he offered to install a recently purchased UV clarifier. Maxsell’s motto is “Friendship Through Service” and it was certainly demonstrated.

We have had a lot of work done on our house since we moved in this past July. Simpson Company was by far the best of all the workers and contractors that we have used. Steve Simpson came by with his border collies to give me an estimate on replacing an existing flagstone terrace and removing a Koi pond. He also addressed some drainage issues and gave me some ideas on how to beautify a dirt side yard that had previously been a dog run. Steve was very prompt in emailing the proposals to me. (Don't let his laid-back demeanor fool you!) They are busy and were not able to begin the work for a few weeks after we accepted their proposal, but Steve Simpson kept me informed of the status via email and phone. Due to rainy weather the agreed upon start date was delayed for a few days, but I was informed and agreed to the new start date. Once the crew arrived, they worked hard and fast to create a beautiful terrace with buried drain pipes and proper grade to drain water away from my house. One thing that was especially nice is that they cleaned up and stored their tools at the end of each day. The plan for the terrace sort of evolved during the process and my input was considered in the design but in the end Simpson's "experts" created a very pleasant terrace with curved edges and a small curved planting bed. My neighbors keep stopping by to admire it. The only problem we had was when a separate fence company (Simpson Co. does not install fences) did not arrive at the agreed upon date to install the fence. By the time they finally showed up, the landscaping had been completed and the fence guys made a mess of the yard during the fence installation. The good guys from Simpson company came back out as soon as I called, cut some of the pavers to fit around the fence and tidied up the area. I highly recommend Simpson Company.
