"I was stressed to the max thinking the home I just purchased had a foundation issue after being told so many things from different companies I turned to Angi’s list and I had totally forgot about my appointment with Rainpros Joel ended up doing the inspection and literally saving me from a stress stroke. He was patient and explained everything as clear as he could over the phone. I have a busy life so it’s not easy to work with me and Joel did just that.

"The Job: Work was satisfactorily completed except this vendor should be supervised. -Gate panels replaced were well done and shaped like previous, but were not sanded on top, leaving a 'rip cut' finish. -Fencing Repair completed, post replaced, sagging addressed, BUT dislodged two panels further down the fence...basically, dno ue diligence in checking their work and unintentional impacts. -Minor debris left behind, did not impress. NO SHOW for original estimate request... insisted they had provided an estimate already! They wrongly a**-u-med the address they went to coincidentally on same day was mine (different project)! Attention to customer care missing... Rule #1: NEVER argue with customer / client, specially when you the contractor are wrong! Would not process through Angi Pay, because they are afraid of fraud? Why are they here?"

Cervantes Maintenance - Your Trusted Lawn and Yard Work Experts in Seattle. With over 10 years of experience, we deliver top-notch solutions to transform your outdoor spaces. Contact us today!

"Cervantes Maintenance came highly recommended by my real estate agent to give my neglected yard a makeover. The first items were functional, trim and shape a giant rose bush and laurel (hedge row) inside the yard along with overgrown vines and lavender sprawl along an extensive retaining wall. Next came the magic. The north and east (front) sides of the house get little sun. Grass was patchy, soil uneven and steep, and moss was destroyed by crows eating the grub infestation. Cervantes treated the soil for grubs and came up with a dramatic landscape design replacing the grass with a flat stone walk way and level patio, gravel and mulch, with a drainage system. They also pressure washed the walkways and front steps, making my entire yard welcoming and brand new. The whole project took two days. Crews worked tirelessly in the rain. Friendly service, on the spot problem solving. Competitive price. Sarah has an instinctive design eye and came up with the solutions and design for me."

Lawn care fertilize or treatment services FAQs

How often you need to fertilize your lawn depends on its health. A healthy lawn might only need fertilizing once a year, while one in poor condition could benefit from fertilization every six weeks. Look for signs like poor growth or discoloration to determine if your lawn needs more nutrients.

You can fertilize your lawn right after mowing, and professionals often recommend it. Fertilizing right after a fresh cut gives the fertilizer time to absorb before the next cut or watering. Just make sure to collect any grass clippings before you begin so they don't block the fertilizer from reaching the soil.

Over-fertilizing your lawn can put it at risk of “fertilizer burn.” Too much fertilizer can cause brown or yellow patches to develop, scorch grass blades, and damage the roots. It's important to follow the recommended application rates to keep your lawn healthy. If you’re unsure, contact a local lawn care professional to determine the right amount of fertilizer for your property.

You can use compost instead of fertilizer. Compost adds natural nutrients to your soil and can be used alongside or instead of traditional fertilizers. While fertilizers provide a quick nutrient boost, compost helps build long-term soil health and fertility. Using compost in your lawn is a great way to improve soil health and support strong root growth.
