"Michael came by the house and gave me a recommendation and estimate on what it would take to guarantee that my basement wouldn't flood. He was very knowledgeable and professional with his quote. He had recommended widening my drain and installing a french drain as a surefire way to fix the problem. However, he did say that if I don't decide to install the additional french drain and only go with widening the drain, he recommended that I go with a plumber instead. That helped solidify that he was giving an honest opinion an estimate of the work to be done. I ended up deciding to do the work, at first, but after having a weekend to think about it, I was reconsidering my decision since in the past I also wanted a patio done and decided to kill two birds with one stone. I had put down a $1100 deposit and since I cancelled the job within three business days, they refunded me my deposit, no questions asked. It was relieving to see that I didn't have to jump through any hoops to cancel after I had changed my mind. I will definitely reach out to them in the future if I need other drainage solutions but at this point I decided to forego the drain solution and see if I can fix it with building a patio instead.

"Horizon Landscaping was outstanding. We needed to have brick and concrete removed and replaced with regular pavers. Horizon also made some repair to the base of a brick wall. I am very pleased with the final result. It was easy to get a quote, an initial contract and schedule the work. The team was punctual and performed the work quickly without any challenges. Their pricing is very competitive and reasonable. I hope to work with them again!"

"It looks beautiful. Brian's crew took out the old concrete slabs and put in beautiful red/grey pavers. The walk goes from our front steps to the driveway.

"Luis and his team did outstanding work. They were very neat and clean during the construction. They also are very honest about anything. They poured a large concrete patio with a retaining wall and helped fix a drainage issue we had. They also had to make sure the concrete could hold our swim spa. It looks great and I won't call anyone else in the future. Couldn't be happier with the results."

"Concrete looks good and after the first rain NO standing water on the area. Just what we wanted to accomplish with this concrete replacement job. The crew on-site worked very hard in the heat 90+ degrees. Being a small job 200 sq ft of tear out and replace they were the only company out of six calls that responded. Great Job"

"Provided a quote that was very competitive with another firm for some concrete and fence work we needed to keep rats out of our backyard. We ended up going with the other firm who was able to start sooner. I was very impressed with the estimator and his knowledge and professionalism, and the quote was very thorough. Would definitely contact them again for future work.

"Removed old concrete patio: This was an old 1963-era concrete slab. Massive. Mike & his team brought in jackhammers and made quick work of it. Waterproofing: Removing the old slab revealed a damaged (and possibly leaking) portion of the house wall, which Mike's team repaired well. Replaced with new patio: Mike's team poured a new cement layer, then installed a new flagstone patio surface on top of that. Also a new step (concrete with flagstone exterior) at the door threshold. They also re-installed an iron railing which had been part of the original patio configuration. The job went well in all respects. We're happy with the team's work and with the new patio. I've worked with Mike and Diversified Contractors several times now. Each time, Mike has had good ideas & suggestions. Each time, his team has demonstrated excellent skills. Again, I'm looking forward to our next project."

"Austin Wells handled our sinking concrete pad and cracks near my garage. He explained everything, neat, and very professional. My wife and I appreciated how he wore a uniform and conducted himself in as an expert in his field. I would definitely call JES again, in particular, Austin Wells to handle any other concrete leveling issues."

Figuring out how many bars you need isn’t a one-size-fits-all equation. A structural engineer or experienced concrete contractor will look at your slab’s thickness, the loads it must carry, and local code requirements, then run the numbers for you. That quick consultation protects your budget and keeps the finished slab safe, level, and up to code.
Match the metal to the job. For light, thin pours like a sidewalk, welded wire mesh often does the trick. Thicker slabs—driveways, garage floors, foundations—usually call for traditional steel bars. If your site sees salt, humidity, or coastal spray, spend the extra cash on galvanized or stainless steel to fend off rust and avoid future repairs. When in doubt, a concrete pro can confirm the best fit for your project and budget.
Stainless steel costs more up front, but the alloy can last 75 years or longer with little to no rust. That longevity means fewer repairs, less maintenance, and peace of mind for structures exposed to salt, moisture, or de-icing chemicals. If you’re pouring near the coast or in a humid climate, the extra dollars now can save you multiple replacements down the road.
An engineer will review the slab’s thickness, span, soil conditions, and expected loads, then specify bar size, spacing, and grade. Skipping that step or guessing can leave you with cracked concrete or a blown budget. For a modest consultation fee, a local engineer or contractor can do the math and hand you a rebar schedule that meets code and keeps your project on solid footing.
