"This Mom & Pop business Needs Work. The Wife is easy to talk to very nice customer service skills. The Husband is a No Mannered Brute. He comes to do the work always in a hurry, for 2 seasons I have complained about a leak in my system, he Never took the time to find it. He sent me several Nasty texts, which I will never post, all because his wife is very nice and I will Not try to hurt the business. Just want customers to be aware. As this season is winding down maybe the husband can take some customer service Classes, First How to respect your customers. Second, Take time to listen to your customers. There are plenty more classes you should take but I Don?t have that Kind of Time. I should have written this review months ago, but I never write a review when I am angry.. I got a Great Company who Fixed All of my Problems and the customer service is Fantastic (Water Workz) The Best around.. Good Luck Drew Harp.. "

Lotus LLC offers, Irrigation, water features, and pond maintenance and installation. We also offer aquarium service and design of fresh water tanks and plants. We also offer dryer vent cleaning. Irrigation service calls are $70 Start ups for irrigation systems are $125 for 1-4 zones. Additional zones are $20 per zone. During start ups, we turn the water on, make sure the main is holding and not leaking. We then run through the zones via the controller, checking each head for proper precipitation rates and coverage. We will make any recommendations to keep the system working to its peak performance. We will make any necessary repairs, replacements and adjustments. Should the system be in disrepair. We will give an estimate of the repair cost. Should it be greater or near the cost of a new system, we will design and give an estimate to install a new system. Irrigation winterizations are $100 for 1-4 zones and $10 for each additional zone. Estimates for new systems or zone additions(add on) are free. For estimates, we come by to discuss the areas that are in need of irrigation. We design on the spot and give a rough estimate. If interested, we then will email you a formal estimate along with a contract. Sign and return the contract with contract guidelines fulfilled. Landscaping is general. Ie weeding, mulching, edging, leaf clean up, sod and seed, ground clearing. We love to make pea gravel pathways and walkways. As well as build natural stone steps. Prices on these services are based upon the scope of the work. Ie how large an area can greatly effect the price. Contact us to set up a meeting so we can give the best price possible based on the work needed. We can do this much easier by coming to you and looking at the job before we give a number. Pond and water feature service and installations. Service calls for ponds are $70. We offer full pond cleaning, filter cleaning, stream cleaning and grounds clean ups. We will test the water and see whats lacking and whats bountiful. After testing we will recommend a dosing schedule and the proper bacteria, or chemical to get the water on point for your plants and fish and for your enjoyment. Estimates for new ponds or water features are free and we love to chat about what you want! Aquariums, We love fresh water aquariums!!!, Service calls for tanks are $70, and service are based on time and materials. Hourly time is $50 and materials can vary. We offer de-ionized water for tanks at $20 per gallon. This water is pure, and a good trick to keep tanks happy, Fresh water plants we have to offer for plantings, only after a full service is done to the aquarium, Full service includes water change, filter cleaning, glass scrubbing, water testing, and dosing of bacteria and fertilizers to ad plants. Dryer vent cleaning,$90. Upon calling you will be asked were the vent comes out. Should it involve a ladder to crawling under a deck the price will 40% higher do to the safety risks involved. We will use a shop vac and a vent brush to clear the vent piping. We will replace any clamps or pipe that is no longer optimal.

"This company is dishonest, and refuses to honor their work. After giving John Ujvery of Lotus LLC a $925 deposit for the installation of an outdoor water feature last November 2018 (he has cashed the check and no work has been performed as of yet). He also installed faulty pond lights, (that stopped working after only one month) costing over $1000. It has been one year and John Ujvery has still failed to come out to complete projects as promised or repair defective products that were under a manufacture’s warranty. He would give dates for the work to be completed, and then cancel without notice. We have emailed and called several times trying to work with him and his company to come to a resolution to the issues mentioned above. More insulting, his company has written accusatory emails stating that we are at fault for the defective equipment. Only after multiple excuses and now not hearing back, we have asked for a refund for the deposit as no work has been performed to date for this water feature and either a refund for the lights or replacement. Lotus LLC is not only dishonest, but lacks any integrity to stand by their work. As of this review we have not gotten a reply in regards to our request for a refund or replacement lights."

Lawn Irrigation questions, answered by experts

Many factors can cause your yard to have lawn depressions. Here are the most common reasons: 

  • Heavy rainfall 

  • Wild animals such as moles, voles, and groundhogs that burrow and tunnel

  • Poor drainage

  • Buried items such as pipes that break down

  • Decaying tree roots or stumps

  • Soil that has compacted

  • Improper mowing techniques

  • Driving heavy equipment and vehicles through the yard

Yes, it's usually necessary to water the lawn after liquid aeration. Water helps activate the aeration product and distribute it evenly into the soil. Proper watering also aids in breaking down soil compaction and enhances the overall effectiveness of the treatment. Follow the recommended watering guidelines provided by the product manufacturer to ensure that your lawn receives the full benefits of liquid aeration and achieves the desired results.

No, grass pavers don’t require a lot of maintenance. However, you’ll need to keep the grass in between the pavers trimmed down just like you would with your lawn.

Whether or not grass will fill in bare spots itself depends on the type of grass you have. For example, grass with rhizomes (e.g., Bermuda grass) and stolons (e.g., Saint Augustine grass) will naturally fill in bald spots as it spreads laterally. However, clump-forming grasses will not spread. 

Mowing is one of the most important ways to maintain your lawn because it encourages grass to grow horizontally, creating a fuller, more uniform yard. On top of mowing your lawn, you’ll want to routinely fertilize your lawn, water it regularly, and take care of pests the moment they arise.
