After what seemed like multiple proposals from different companies I felt overwhelmed. My neighbor suggested I call Gary because she had used him multiple times over the last 20 years and only had amazing things to say. I immediately went home and submitted an inquiry on his website. Gary responded back within 24 hours and came to our house that week to walk the property. He put us at ease right away by telling us the "major issue" could easily be fixed and then outlined other designs that could truly enhance things. Any questions we had he answered. Once the work started his guys were on it. The week was blistering hot and these men worked so hard! They were also incredibly nice and anytime I had questions they would walk me through it. The end product surpassed our expectations. I highly recommend Gary Duff Designs. **★★★★★ — Colleen Stanley, June 2022** > Gary is professional and easy to work with. He and his team completed our project beautifully, and quickly. Our expanded patio and fire pit are a joy. **★★★★★ — HU-892547398, Aug. 2021** > I can’t say enough great things about Gary and his company. He has always provided unbelievable customer service and on many occasions has gone above and beyond. Gary’s landscaping designs are first class. The quality of work on my greenhouse and backyard landscaping is impeccable, as well as breathtaking. My neighbors are constantly complimenting the workmanship and attention to detail. Thank you Gary for always listening to my vision and making it a reality! **★★★★★ — Marc Horowitz, April 2020** > Gary's insight into how to make the most of your property amazes me. He made a few immediate observations about what we/guests see or don't see upon approaching our home, and guided us through a process on how to dramatically improve it. With no direct access to our street from our front door, Gary redesigned our front lawn, carving a serpentine path of unique pavers, and added stone steps to our newly covered front porch and walkway to the curb. He ripped out all of the 40 year old overgrown shrubs from the front lawn and driveway, and replaced them with young and healthy plantings sprinked with lots of colorful trees and flowers. Further, with any visitors formerly only seeing our home from the bottom end of our driveway and the original only point of access, Gary ripped out the deteriorated drive and replaced it with a continuation of the serpentine flow of pavers that now frame the drive and connect to both the new front walkway and a path to our back lawn and pool. > We could not recommend anyone or any company more highly! ## Selected projects - [Wall of Wars](https://www.houzz.com/hznb/projects/wall-of-wars-pj-vj~2525417) - Location: Northport, NY - Photos: 7 - Description: A commemorative space provides the opportunity for quiet contemplation, as well as education and understanding.

They can also stroll along the stone walkway to pay tribute to the loving memorials built into the patio stones. - [Princess Make-A-Wish](https://www.houzz.com/hznb/projects/princess-make-a-wish-pj-vj~2525428) - Location: Not specified - Photos: 5 - Description: For the past 17 years, Gary Duff Designs has collaborated with the creative team at the Make-A-Wish Foundation to design and construct the fantastical ideas of children across the country.

A: Hi Erika, We recessed the unit down into a concrete block vault. We disconnected the pumps and ran them away from the spa. The unit itself had the control on it. --- *Source: Houzz professional profile. Reflects the profile as of 2026-11-09.*
