I'm Tom DiPhillipo. I’ve been a landscaper since I was a teen, first as an employee and then as an owner operator. My wife, Sharon and I began this business in 2001. After decades of experience and many hundreds of satisfied Lehigh Valley customers, I'm confident our experienced and diverse team can help make your landscaping dreams come true. At DiPhillipo's Landscaping & Hardscaping, we will cater to your needs, get the job done quickly, and professionally. We aren't happy until you're happy. We pride ourselves in how many of our customers are repeat and word of mouth referrals. They know we’re dependable, knowledgeable, competitively priced, and pleasant to work with. We are licensed and insured, and have always maintained an A+ rating with the Better Business Bureau. Call now to talk with me about your landscaping ideas and dreams.

"My parents have an in-ground pool and over the years new homes were built behind their house. The new houses changed how the rain runoff comes through their backyard. It actually caused mud to pour into the pool TWICE and costs $3000 each time to empty,clean,and refill the pool. I called multiple landscape/drainage pros for estimates and either they quoted a ridiculously high price or never called back. I found Tom on Angi and he came and looked right away. His quote was very reasonable and he didn’t seem too worried about it. He and his team showed up when they said they would and knocked the project out in 2 days! ( I work construction and thought it would be at least double the time.) They excavated the dirt around the edge of the pool and added a deep layer of river rock plus created a vertical paver wall to ensure the water wouldn’t get in the pool. They also used the removed dirt to create a berm in the backyard to further redirect water. They covered the berm in wildflower seed and straw. Overall, everybody is ecstatic with how they fixed our problem. 100% professional quality. His guys worked non stop and they cleaned up after the job was done. I highly recommend using Tom and his team."

"Chris and his team installed beautiful turf around our gazebo by the pool. Not only does it look great and is maintenance free, it’s like walking on a soft carpet. The dogs love it too! Chris was quick to come out in response to my request and quickly got our turf ordered and squeezed us in to get the job done before the pool is opened. The area on one side was tight so they did it all by hand rather than drive the skid loader over the concrete. They could not have been more accommodating, also working with us on raising an in ground electrical box. Excellent work done by the entire team. I would highly recommend!!"

Retaining Wall Installers questions, answered by experts

Most railroad tie retaining walls have a life span of 20 to 30 years, though you may need to replace your wall sooner if it’s repeatedly exposed to heavy rain, runoff, and excess moisture. Railroad ties are typically treated with creosote, which makes them much more durable than untreated wood. Though they last longer, they don’t last forever. For the most longevity, make sure your retaining wall has a sturdy base and steel reinforcements. You should also install drainage to direct water away from the wall.

Most retaining wall installations can be finished in one to three weeks, but the timeline varies based on factors like wall size and material. The local climate and major weather events, such as storms or flooding, can also extend the project's timeline, as can any holds ups in the permitting process.

A retaining wall can only function as a fence if it’s high enough on all sides to prevent someone from accidentally falling into the pool. However, most retaining walls retain dirt, which means their purpose is not related to safety. There would need to be nothing on the other side of the wall for it to be considered a fence, but in that case, it wouldn’t retain anything and would cease to be a retaining wall.  

Small retaining walls still require a foundation of some kind, typically a concrete footing. This helps to ensure the wall is structurally sound and prevents the ground from shifting over time, especially during those winter freeze/thaw cycles. The footing helps spread the weight of the wall and the load it carries over a larger area of the ground, thus assisting with stability. This is true of small retaining walls, larger rock garden walls, and the like. 

Yes, to build a retaining wall, a permit is required. Similarly, any repairs or modifications to an existing retaining wall require permits. If the planned wall measures higher than 4 feet, most municipalities require designs and permits come through a licensed engineer. In some locations, if the wall is shorter than 4 feet, a permit may not be required. For the requirements in your area, contact your local government.
