"I spent a lot of time trying to find someone that could replace my front steps. Getting someone to actually call back was the first challenge. Then, trying to find someone who does everything we wanted: granite steps, faux stone facing and sides, white railings, and the ability to tear up and lower my walkway then redo it to make the first step 7” was an even bigger challenge. We finally found the right guy/company and we are very happy with the results. Walter Santos of W. Santos Construction did it all for us. He started within days of us accepting his proposal. He was kind, communicated the next steps with us well, and the quality was fantastic. I was outside tonight taking photos and a family was taking a walk stopped me to ask who did the steps because “they make the house.” I took some dry and wet pics after the dust was washed off and I’m very happy with the results. He even came out to finish on Memorial Day."

"Jose came out initially for the quote. Which was very timely ( within a day or 2). Upon meeting him, i was impressed, very polite, attentive, and he asked questions. Some of the questions were repeated, which i appreciated. He was making sure we didn't miss anything. We walked my property, and he listened to everything i said. He was very down to earth, easy to talk to. The next day, he sent me photos of some of the jobs he had finished, before & after. I was impressed. That weekend, he sent me a reasonable quote, which i accepted, happily because i had a previous landscaper that was lazy and left a bit behind. Jose had his work cut out for him. He called me very quickly after and said he had a cancelation and asked if i minded that he came out, i believe that same weekend?. I said ABSOLUTELY!! He came with 3 workers, including his father ( i thought that was sweet). What a job!!! They were here all day long, sometimes on their hands & knees picking grass and weeds. Hard workers, WOW! The experience & technique in trimming my bushes and smaller shrubbery were impeccable. My hydrangea looked so bad, but after they performed their art, she looked beautiful and alive. The edging came out immaculate so much so that my neighbor walked over and asked them how they did that and also complemented them and myself later on. They laid mulch so nicely within the lines and growth. I took before and after pictures. I continue to get compliments by strangers just walking by, and my neighbors asked for their information. I highly recommend Jose and his respectful crew. He has agreed to help with some other things on the days my health isn't at its best. Digging holes, pulling weeds, etc. With notice and some compensation, of course. I am so pleased. I was very excited that day because my beautiful yard had NEVER looked better. What a great bunch. I can't wait to see them for my mow. I gave them a nice tip because they earned it. THANK YOU, GUYS SO MUCH! SEE YOU SOON! ?"

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.

Costs range from $5,000 to $15,000, depending on size, material, and design complexity.

The longevity of flood walls depends on how they were constructed, but most wood, gravel, and cement flood walls last 10 years. While aluminum flood walls may cost far more initially, they can be a good investment as they can last decades and will not be damaged by exposure to the elements.

Generally speaking, a retaining wall should be between 3 and 4 feet high, depending on variables such as the wall-building material, the purpose of the retaining wall, and more. If you want your retaining wall to be taller than 4 feet, check with your local building ordinance office for the maximum allotment. You may also need a special permit for retaining walls over 4 feet tall.

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.
