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."

Retaining Wall Installers questions, answered by experts

To maintain the integrity of your landscape, a retaining wall must be installed if the slope of the angle exceeds 35 degrees. The lean of the wall must be 1 inch per 12 inches in height to disperse the weight of the soil uniformly and guarantee the correct drainage of the soil.

Generally, a railroad tie retaining wall consisting of a single line of ties should be between 3 and 4 feet tall—and the height often tops out at around 6 feet. You can go taller, but you may need additional footings and reinforcements, including a second layer of railroad ties to support the added weight of the soil it’s holding back.

Through proper drainage solutions and compacting the foundation soil.

Poured concrete is likely the cheapest way to build a retaining wall, as this material costs anywhere from $6 to $8 per square foot. The next best budget-friendly option is to use landscaping timbers. These timbers are great for DIY projects, as they don’t require tools to successfully build a retaining wall. Landscape timber costs around $10 to $14 per square foot. Depending on your chosen garden style, you can also go with natural stones or concrete blocks. Natural stones can be expensive if you buy them, but they’re a lot less costly if you can source them from your property. 

Sand and gravel are two suitable options for filling behind a retaining wall. If you’re building your own retaining wall, you’ll complete this part of the process—known as backfilling—after you finish laying the blocks. Make sure not to skip it—otherwise, you could wind up with drainage issues, which can cause your retaining wall to collapse.
