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.

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.

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

Aerate during the growing season, typically in spring or fall, when grass can quickly recover.

If your grass is stressed from being over-trimmed, try watering it heavily and then allowing it to recover for at least two weeks before mowing again. If you notice brown patches where the grass has died off because it’s too short, you should remove the dead grass and overseed the area. Leaving dead patches can invite weeds and other problems, so if you want a totally green lawn, getting rid of dead patches should include removing the dead sections before reseeding the area.

Try the tool test first. A screwdriver or a similarly long, thin tool will work best, as spades and shovels are too big. If something still seems off despite the screwdriver smoothly going into the soil, look for other signs that you need aeration, like thinning grass, discolored areas, and puddles forming on your lawn after light rain. This indicates poor drainage because of too many areas being compacted.

Before you put down grass seed, you should cultivate your soil or add two inches of topsoil. You should also put down fertilizer at the same time as your seed to prompt healthy growth. Be sure to water after you put down grass seed, especially for the first two weeks.

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.
