"White Garden Designs is the Best!! I have used him for at least 10 years now and nobody cares more or is more detail oriented than Charlie. I have recommended him and his company to dozens of friends and everyone was as pleased as I am. They always show up on time and if there is ever a problem (which I haven't had) they will always make it right. He takes pride in his work and it shows. He also is a Koi pond specialist, designing and maintenance. This man does it all. He is the go to guy for all your landscaping and pond needs."

"Marino's has always been incredibly responsive and customer satisfaction oriented.  The workers are very nice to deal with and they know what they're doing.  I've had many emergency water outages and a couple of basement floods caused by rain, and the Marino's folks are always there to help whether it's Sunday night or some other odd time.  I've never had to wait when I've had an emergency.  I highly recommend them.

"We hired Northwind Designs to install a crushed stone driveway and to incorporate some intricate masonry to better connect the driveway to our garage and a nearby patio. The team was fast and efficient, and they have a keen eye for aesthetics. Look no further than the portfolio on their websiteâ itâ s outstanding work. We have since rehired Northwind Designs to help install an outdoor shower (with attendant masonry/landscaping) and a fence. Highly recommended."

Fountains FAQs, answered by experts

Most pond installations take 3-10 days, depending on excavation, liner placement, and filtration setup.

Yes, your fish should stay alive in a frozen pond if you winterize it properly. By ensuring your pond has enough oxygen, good water quality, and a hole to release harmful gases, your pond and fish have the best chance of staying alive and healthy. However, if you have tropical fish, they should be overwintered indoors.

Seeps and springs form when groundwater reaches the earth’s surface. The main differences between them are the amount of water and the flow rate. Seeps are smaller than springs and consist of water that’s stagnant or flows slowly. Springs contain more water and flow more quickly.

Backyard water features can add serenity to your property, drown out neighborhood noise, and serve as a focal point to a stunning landscape design. In some cases, a properly installed and maintained water feature can add to your home’s value. Just be sure to check with your insurance company before installation since some features may affect your premiums.

A koi pond may add value to your home if it’s a feature sellers are looking for. Like pools, ponds can affect your property value depending on their condition, whether they’re a popular selling point, and how well they’re incorporated into your home’s landscape.
