If you are comparing monthly lawn care cost in Seattle or Kirkland, you have probably discovered that nobody wants to give you a straight number. One company quotes $120 a month. Another says $350. A third will not commit to any price until they do a site visit next Tuesday. And none of them will tell you what is actually included until you sign something.
This article fixes that. We break down real monthly lawn care prices in the Seattle metro area for 2026, organized by what you actually receive at each common budget level: $150, $250, and $400 per month. Real local pricing. Real service inclusions. No vague ranges, no national averages, and no hidden line items.
How Much Does Monthly Lawn Care Cost in Seattle in 2026?
Monthly lawn care cost in Seattle ranges from $100 to $450 per month in 2026, depending on lawn size, service level, and location. Basic biweekly mowing costs $100 to $175 per month. Weekly mowing with seasonal treatments costs $200 to $300 per month — the sweet spot for most Seattle and Kirkland homeowners. Full-service plans with bed maintenance, leaf cleanup, and irrigation coordination cost $325 to $450+ per month. Prices reflect 2026 Seattle metro labor rates, which run 20 to 30 percent above national averages.

Ranges assume a standard residential lot with moderate access. Properties with larger lot sizes, heavy tree coverage, steep slopes, or restricted access fall at the upper end of each tier.
The Bottom Line
Most Seattle and Kirkland homeowners with a standard residential lot spend $200 to $300 per month for a plan that keeps the yard healthy year-round. That covers weekly mowing, seasonal aeration, lime application for pH correction, moss treatment, and overseeding. It is roughly the cost of two dinners out per month, in exchange for a lawn that does not turn into a moss field by February.
Is Lawn Care More Expensive in Kirkland Than Seattle?
Lawn care cost in Kirkland runs 5 to 15 percent higher than the Seattle city average. Two factors drive this: Kirkland lot sizes are generally larger than equivalent Seattle neighborhoods, and the Eastside market commands a modest labor premium. A $250 per month plan in Seattle might run $275 to $290 per month in Juanita, Rose Hill, Finn Hill, or Houghton for an equivalent service level.

What Does $150 per Month Lawn Care Include in Seattle?
At the $100 to $175 per month range, you are paying for basic lawn mowing service. This tier covers biweekly mowing during the Pacific Northwest growing season (typically April through October), string trimming around beds and fences, hard edging along walkways and driveways, and blowing clippings off all hard surfaces. During dormant months (November through March), visits drop to monthly or as-needed.
What this tier does NOT include: core aeration, dethatching, overseeding, moss treatment, lime application, fertilization, weed control, seasonal cleanups, leaf removal, irrigation management, or bed maintenance. None of the seasonal treatments that actually improve turf health are part of basic lawn care at this price.
The Biweekly Mowing Tradeoff
During peak growth in April, May, and June, Seattle and Kirkland lawns grow 2 to 3 inches per week. Biweekly service means the crew is cutting 4 to 6 inches of growth in one pass, which violates the one-third rule (never cut more than one-third of the blade height at once). This shocks the grass and weakens roots. If $150 per month is the hard ceiling, ask your provider to switch to weekly mowing in April through June and biweekly the rest of the season.
What Does $250 per Month Lawn Care Include in Seattle?
The $200 to $300 per month tier is where monthly lawn care actually improves your lawn instead of just maintaining its current condition. It combines consistent weekly mowing with the seasonal treatments that address the root causes of Pacific Northwest lawn problems: soil compaction, acidic pH, thin turf density, and moss.
Seasonal Treatment
Optimal Window
Purpose
Core aeration
September (primary) or March
Relieves Seattle glacial till clay compaction. Enables water, air, and nutrients to reach roots.
Overseeding
Immediately after aeration
Fills bare patches with perennial ryegrass and fine fescue seed adapted for Western Washington.
Lime application
March or October
Corrects acidic soil pH (most Seattle and Kirkland lawns sit at 5.0–5.5; grass prefers 6.0–7.0).
Moss treatment (iron-based)
February–March or October–November
Kills existing moss. Dead moss is removed before overseeding.
Spring cleanup
March–April
Debris removal, first mow of season, bed edge cleanup, hardscape blowoff.
What this tier does NOT include: multiple leaf cleanup visits in fall (heavy tree coverage typically requires 2 to 4 additional cleanups at $50 to $100 per visit), garden bed maintenance beyond basic edging, irrigation system startup or repair, or commercial fertilization and herbicide application, which requires a Washington State Department of Agriculture Commercial Pesticide Applicator license.
For why Seattle's acidic glacial till soil creates these specific problems, see our Seattle Lawn Aeration Guide.

Weekly mowing plus seasonal treatments. Free property assessment for Kirkland, Seattle, and the Eastside.
What Does $400 per Month Lawn Care Include in Seattle?
At $325 to $450+ per month, you are paying for full-service lawn care that requires zero thought from you. The crew shows up on the same day every week, handles the lawn, beds, edges, leaves, and every seasonal treatment on the correct calendar month.
What is included at this price — everything in the $250 tier, plus: year-round weekly mowing with priority same-day scheduling, full seasonal treatment calendar (aeration 1 to 2 times per year, dethatching, overseeding, lime, iron-based moss treatment, grub monitoring, and soil amendment applications), garden bed maintenance including periodic weed pulling and mulch top-off coordination, fall leaf management with multiple cleanup visits during peak leaf drop (October through December), irrigation coordination including spring startup, fall winterization, and smart controller seasonal reprogramming, and priority communication with direct contact for storm damage response.
Complete Property Care. Same Crew, Same Day, Every Week.
Serving Kirkland, Bellevue, Seattle, and the Eastside.
Two properties on the same Kirkland street can have a $150 per month difference in lawn care cost. Here is what moves the number:
Property size and lawn square footage: The largest factor. A 3,000 square foot lawn takes 20 to 30 minutes to mow. A 10,000 square foot lawn takes 60 to 90 minutes. Most companies price mowing by square footage, and treatment costs scale proportionally.
Mowing frequency: Weekly mowing costs 60 to 80 percent more per month than biweekly, but produces a significantly healthier lawn. During peak spring growth (April through June), the difference in turf quality is dramatic and visible.
Tree coverage and shade: Properties under mature deciduous trees generate massive leaf volume in fall and promote moss growth, increasing the need for frequent treatment. Shade-heavy lots tend to fall at the upper end of each pricing tier.
Terrain and slope: Seattle and Kirkland are cities of hills. Mowing a sloped lawn takes longer, requires different equipment, and increases crew fatigue. Flat, accessible lots are the least expensive to maintain.
Current lawn condition: A lawn being rescued from years of neglect costs more in year one because it requires catch-up work. Year two and beyond typically cost less because the turf is healthier and needs less intervention.
What Is Not Included in a Monthly Lawn Care Plan in Seattle?
Tree pruning or removal: Tree work in Washington State requires a Registered Tree Service Provider (RTSP). Lawn care companies that trim hedges and shrubs are not qualified for tree work. LandscapingFactory handles shrub and hedge trimming. For actual tree work, we refer to qualified ISA-certified arborists.
Fertilizer and herbicide application: Commercial application of fertilizer, herbicides, fungicides, or pesticides requires a WSDA Commercial Pesticide Applicator license. Soil amendments like lime, gypsum, and compost do not require this license. If a lawn care company quotes you for fertilizer application, ask to see their WSDA license number.
Irrigation system installation: Monthly plans may include seasonal startup and winterization of an existing system, but installing a new system is a separate project ($3,000 to $10,000 depending on zone count and property size).
Hardscape work: Paver repair, retaining wall maintenance, fence work, and pressure washing are quoted as separate services.
⚠️ The License Check
Before signing any lawn care contract in Seattle or Kirkland, ask two questions: (1) Are you licensed and insured for the services you are quoting? (2) If your quote includes fertilizer or weed control, what is your WSDA Commercial Pesticide Applicator license number? A company that cannot answer question two should not be applying chemicals to your property.
Is a Monthly Lawn Care Plan Worth It vs DIY?
For most Seattle and Kirkland homeowners, a monthly lawn care plan is cheaper long-term than DIY when you account for equipment costs, time value, and the renovation bill that typically follows years of skipped treatments.
A quality self-propelled mower costs $400 to $800. An edger runs $100 to $300. A broadcast spreader is $50 to $150. A leaf blower is $150 to $400. Total equipment investment: $700 to $1,650. Add fuel, blade sharpening, and replacement parts at roughly $100 to $200 per year. Time investment: 100 to 150 hours per year during the growing season. And most DIY homeowners skip the seasonal treatments (aeration, lime, overseeding, moss control) because they do not own the specialized equipment, which leads to a full renovation bill of $2,000 to $5,000 within 3 to 4 years.

How to Compare Lawn Care Quotes in Seattle Without Getting Burned
Getting three lawn care quotes is the minimum. Here are the seven questions that separate a real quote from a sales pitch:
1. What is the mowing frequency? Weekly and biweekly are dramatically different services. Always confirm.
2. What seasonal treatments are included? Ask for a specific written list. 'Seasonal treatments included' is not an answer. 'Core aeration in September, lime in October, moss treatment in February, overseeding with aeration' is an answer.
3. How many fall leaf cleanup visits are included? One pass in November and unlimited visits throughout October through December are completely different service levels. Properties with heavy tree coverage need 4 to 8 cleanups per season.
4. Is debris hauling included? Some companies charge separately for hauling after cleanups. Confirm before signing.
5. What happens during winter months? Does the plan pause entirely from November to February, or does it include light maintenance visits?
6. Is the crew consistent? Will the same people show up each week, or does the company rotate random crews?
7. Are they licensed and insured for Washington State? Ask for the Washington contractor license number, proof of insurance, and (if fertilizer or herbicide is quoted) the WSDA applicator license number. Hesitation on any of these is a red flag.
Frequently Asked Questions About Lawn Care Cost in Seattle and Kirkland
How much does monthly lawn care cost in Seattle? +
Monthly lawn care in the Seattle metro area costs $100 to $450+ per month in 2026, depending on service level and property size. Basic biweekly mowing runs $100 to $175 per month. Weekly mowing plus seasonal treatments (the most common plan) runs $200 to $300 per month. Full-service plans with bed maintenance, multiple leaf cleanups, and irrigation coordination run $325 to $450+ per month.
How much does lawn care cost in Kirkland WA? +
Lawn care cost in Kirkland runs 5 to 15 percent higher than the Seattle city average due to larger typical lot sizes and Eastside labor rates. A standard monthly lawn care plan in Kirkland neighborhoods like Juanita, Rose Hill, Finn Hill, or Houghton typically costs $220 to $360 per month for a 5,000 to 10,000 square foot residential lot in 2026.
What is included in a monthly lawn care plan in Seattle? +
A standard Seattle monthly lawn care plan ($200 to $300 per month) typically includes weekly mowing, edging, string trimming, and hardscape blowoff, plus 3 to 5 seasonal treatments per year: core aeration, overseeding, lime application, iron-based moss treatment, and spring cleanup. Exact inclusions vary by provider, so always request a written service list.
Is weekly mowing necessary in Seattle and Kirkland? +
During peak Pacific Northwest growth (April through June), yes. Seattle and Kirkland cool-season grass grows 2 to 3 inches per week in spring. Biweekly mowing during this period violates the one-third rule and damages the turf. Weekly mowing from April through October with biweekly service in shoulder months is the most effective schedule for this climate.
Why is lawn care more expensive in Seattle than national averages? +
Seattle's climate creates specific challenges that increase labor and treatment needs: nine months of rain promote moss and compaction, acidic glacial till soil requires annual lime correction, heavy shade from mature conifers limits grass growth, and the explosive spring growing season demands weekly mowing for six months. Seattle metro labor costs also run 20 to 30 percent above national averages.
Is LawnStarter or TruGreen cheaper than local lawn care companies in Seattle? +
LawnStarter and LawnGuru typically offer lower per-mow pricing ($36 to $68 per cut in Seattle) than most local companies, but they provide mowing-only service with rotating crews and no seasonal treatments. TruGreen offers lawn treatments ($65 to $225 per application) but no mowing. Local Seattle and Kirkland lawn care companies typically cost more per visit but include treatments, consistent crews, and local expertise. Total annual cost is often similar.
Can I bundle lawn care with pressure washing or gutter cleaning in Seattle? +
Yes. Most local Seattle and Kirkland lawn care companies, including LandscapingFactory, offer bundled property care plans that combine monthly lawn service with pressure washing, gutter cleaning, pruning, and seasonal cleanups. Bundled pricing typically saves 10 to 20 percent compared to booking each service separately because the crew is already on site with equipment.
How do I know if my Seattle lawn needs the $250 tier or the $150 tier? +
If your lawn has visible moss, bare patches, compacted soil, or a spongy feel underfoot, it needs treatments beyond mowing. The $150 tier maintains appearance but does not address these conditions. The $250 tier corrects them. If you are unsure, most reputable Seattle lawn care companies provide a free lawn assessment and recommend the appropriate tier based on actual turf condition.
Do lawn care plans in Seattle run year-round or only during the growing season? +
Most monthly lawn care plans in Seattle run 10 to 12 months. The growing season (March through November) includes active mowing and seasonal treatments. December through February is typically light or no-visit months, but some plans include winter monitoring, light cleanup, and early February moss treatment. Monthly pricing is usually averaged across the year for consistent billing.
What is a realistic lawn care budget for a standard Kirkland or Seattle lot? +
For a typical 5,000 to 8,000 square foot residential lot in Kirkland, Seattle, Bellevue, or Redmond, budget $200 to $300 per month for a plan that includes weekly mowing and seasonal treatments. This is the range where most homeowners see meaningful improvement in lawn health within the first year.
Is a monthly lawn care plan worth it compared to DIY in Seattle? +
For most Seattle and Kirkland homeowners, yes. DIY lawn care requires $700 to $1,650 in equipment, plus 100 to 150 hours of yearly labor. Most DIY homeowners skip seasonal treatments (aeration, lime, overseeding) because they do not own the equipment, which leads to lawn degradation and a $2,000 to $5,000 renovation within 3 to 4 years. A professional monthly plan at $250 avoids this cycle.
Do lawn care prices change throughout the year in Seattle? +
Most monthly lawn care plans average the annual cost across 12 months for consistent billing. You pay the same amount in July (active weekly mowing plus irrigation coordination) as you do in January (minimal or no visits). Some Seattle companies offer seasonal billing that charges more in summer and less in winter, which can work if your household budget fluctuates seasonally.
How long before I see results from a Seattle monthly lawn care plan? +
Mowing improvements are visible immediately. Soil and turf health improvements from core aeration, overseeding, and lime take one to two full Pacific Northwest growing seasons to show significant results. Moss reduction is visible within the first year. Full lawn density and weed suppression from thick turf typically develop by the end of year two.
What if I only need lawn care during part of the year in Seattle? +
Some Seattle companies offer seasonal-only plans (April through November). These typically cost 10 to 15 percent more per month than annual plans because the company cannot distribute revenue evenly across the year. If you only need mowing during the growing season and plan to handle winter yourself, a seasonal plan may work, but skipping February moss treatment and March lime application often means the lawn enters spring in worse condition.
Does LandscapingFactory serve Kirkland, Bellevue, Redmond, and the Eastside? +
Yes. LandscapingFactory is a Seattle-based lawn care and landscaping company with Kirkland as our primary service area. We serve all Kirkland neighborhoods (Juanita, Rose Hill, Finn Hill, Houghton, Totem Lake, Bridle Trails, downtown Market area), Seattle (all neighborhoods), Bellevue, Redmond, Sammamish, Issaquah, Renton, Bothell, Woodinville, Mercer Island, Shoreline, Lake Forest Park, and surrounding King County communities. Free on-site lawn care quotes for all service areas.
The Right Monthly Lawn Care Plan for Your Property
A $150 per month basic plan keeps the lawn cut but does not move the needle on turf health. A $250 per month standard plan with seasonal treatments actively corrects the conditions that cause Seattle lawns to fail. A $400 per month full-service plan handles everything so you never think about it.
