Grass Master Hydroseeding in Woodinville

Great work! I Had about 4500 sq ft of erosion control on a hill side that needed to get done, they came out and did a fantastic job getting it in May. Unfortunately a few days later we had a monsoon rain storm non stop for 2 days here in mill creek. It washed away a good portion of the hydro seed. I waited to see what was gonna happen and surprisingly pretty good amount grew just fine, but some washed away. The guys came back out and resprayed the washed out areas and were fantastic to work with. So thankful for their help and will use again!!

Jason at Grassmaster has an incredible team! Quality over quantity should be their tagline. They built a large wall area to level off a decline in my wife's dream garden. They have the skills, knowledge, and know-how to get your job done right. You cannot go wrong with Jason and Brandon at Grassmaster. Earlier this spring, they performed an aeration and top-dressed my lawn. They are my go-to for any landscape work, and I will use them again.

30ish days away from more grass! What was once a field of blackberries covering 30 years of garbage is now going to be more eye catching. Nicole in the office was super informative and easy to work with. Chris came out and set the expectation and got to work. Now we wait. We wait for the temperature to rise so I can mow that new lawn! Approximately a month from now. What an improvement. Thanks Grassmasters.

Quick service, great crew. The guys are just leaving my property. I appreciate that they were on time, and efficient. They answered all my questions and provided information and advice. If I ever need seeding again I'll definitely be a returning customer. 2 month update: Very impressed with how the grass is growing in. Just followed the handbook they provided and things are going great! Thanks again for the service!

Happy with this service. They covered all the parts we wanted and offered simple caring instructions. Hydroseeding process was quick and easy

Grass Master did an awesome job! Clean work, professional and friendly crew that kindly answered all of my questions - I am new to hydroseed and had many!! From start to finish they were a pleasure to work with and we already love our new yard, so excited to watch the grass grow! Also loved to find out they are a small, family business with two sisters running the office - love to support local families in our community! Highly recommend!

Really surprised by the negative review? I heard great things about this company so decided to give them a try and my experience was wonderful! Nicole, Amanda, and Hugo were timely, professional, personable, and communicated details completely. You have to give the lawn some time, a few days isn't enough, but following the manual and watering instructions, after about a week things were happening! My lawn really looks beautiful, highly, highly recommend.

Terrible value - We had Grass Master hydroseed our lawn two weeks ago. After they left we noted some areas where the mulch coverage was missing, with about 50% of the soil uncovered/unseeded. We informed Amanda and Nicole at Grass Master (GM) by phone and emailed pictures, but the owner refused to come back and check the areas. With Grass Master you'll be ask to pay more for no quality guarantee, and could receive a sparse hydroseeding application, which means you'll wait twice as long and spend twice as much time and money watering! See the brochure picture. You are really paying a lot for hand seeding. The service which is supposed to be guaranteed and includes a follow-up hand seeding and fertilizer, was sold to us as an extra for $100. After reading GM's BBB response to our complaint, we realize that GM's lost money because we previously cancelled appointments due to property flooding, which was not our fault (see flooding pic). So to make up for their loss, GM applied a very light hydroseeding and asked for an extra $100. We don't want them to hand seed in 1.5 months where weeds will have grown, when it should been hydroseeded the first time. We could have hand seeded ourselves for a fraction of the cost.
