Tuff jobs is a proud family business owner that specializes in deck building, land clearing, landscaping, and pretty much your local jack-of-all-trades. I pride myself in delivering quality work...exactly what the client needs and asks for. My 5 star reviews and business name is just one example of that. I'm new to Angi, so most of my reviews are in a different place. If you want the link, just ask! Will you be the next person to give me 5 stars? Reach out and let's tackle that project together.
"I have been in my house for 15 years. Every year the "clean the green" season comes up. I have to admit I am used to being disappointed by the companies I have hired. This year I based my decision on who to hire from past reviews. Stryker was on time and did an amazing job. The roofs look new. Did he actually WASH the gutters after cleaning out the debris?? He did an amazing job on some old brick walkways. Stryker is a different breed. I communicated my issue with plants and birds and the chemicals used. He did the majority of the job with no chemicals. No bleach smell when he was gone. I am having him back for a third time...This is a quality guy."

FAQs for lawn fertilization and treatment projects in Sammamish, WA
The cost to reseed or overseed a lawn is about $1,050 on average, ranging from $450 to $1,700, depending on lawn size, seed type, and location. Popular seed types for residential lawns include bahia, fescue, and Bermuda. Keep in mind that it costs $0.10 to $0.20 per square foot to seed or overseed a lawn. Additional cost factors may include:
Fertilization: $80–$400
Soil testing: $700–$2,100
Yard cleanup and leaf removal: $200–$560
Treating weeds: $110–$325
Mowing: $50–$210
On average, the cost of lawn fertilization is $250, ranging from $80 to $400, depending on the size of the lawn, its current condition, additional treatments, number of applications, fertilizer type, and location. Keep in mind that labor, tools, and equipment make up 80% to 90% of the total cost of lawn fertilization. Additional lawn treatment options include:
Lime treatment: $100–$150 per 1,000 square feet
Crabgrass treatment: $30–$80
Grub treatment: $30–$80
Mulching: $150–$400
Dethatching: $265–$295
The frequency with which you should fertilize your lawn depends on its overall health. Healthy lawns with healthy soil may only need to be fertilized annually. On the other hand, you may need to fertilize lawns with shallow roots, poor soil, or neglected or over-fertilized every six weeks. To determine the best fertilizing schedule for your lawn, consider hiring a professional lawn fertilizing service and consult them about recommended frequency based on your lawn’s health.
Lawn aeration costs between $75 and $350 on average, depending on the size of the lawn, aeration type, slope of the lawn, soil type, lawn prep, and location. Keep in mind that it costs an average of $0.10 to $0.35 per square foot to aerate a lawn that’s less than 1,000 square feet. Different types of lawn aeration include:
Spike aeration: $85
Core aeration: $200
Liquid aeration: $75
Whether organic or synthetic fertilizers are better for your lawn depends on your goals, budget, and plans for other lawn treatments. Organic fertilizer costs more but is likely to benefit your lawn more in the long run by improving the soil as well as feeding your grass. Synthetic fertilizers get faster results but don’t enrich the soil and may contaminate nearby bodies of water if you live on a shoreline. A hybrid fertilizer may be an option to give you the benefits found in both organic and synthetic fertilizers.
