Frequently Asked Questions

Published consumer guides span about $0.07 to $0.35 a square foot for a home lawn, and HomeGuide's figure for 5,000 square feet of lawn is $1,000 to $1,750. Most hydroseeding companies also have a minimum job fee, which HomeGuide puts at $300 to $500 or more. Soil prep, grading, slope and access change the number, so we price your Phoenix lawn after seeing it and put that price in writing before any work starts.

For a bermuda lawn larger than a small patch, usually yes. It costs a fraction of sod, and the mulch layer holds moisture and resists wind far better than dry seed on bare desert ground. If you need the lawn usable within a week, sod is the better buy.

You wait. A seeded bermuda lawn takes about a month to establish, it needs several short waterings a day at first, and it should stay off-limits to heavy play until it fills in. It also only works in the right season: bermuda seed sown in winter will sit dormant.

Small rental and bagged hydroseed kits exist, and they can work on a patch. On a full yard the hard parts are the prep, getting an even application rate, and the watering in Phoenix heat. New seedings here usually fail from compacted soil or a missed watering on a hot afternoon, not from the spray itself.

For a permanent bermuda lawn, plant from May through August, when University of Arizona Extension lists seeding. For a green winter lawn of ryegrass, the extension window for Phoenix is October 10 to November 10. Spring and early fall are transition periods when neither grass establishes well from seed.

Extension advises against overseeding a new bermuda lawn in its first winter. The young bermuda has to green up and regrow in spring while competing with vigorous ryegrass. Let it go dormant and blonde the first winter.

Under good conditions seed sprouts within about a week, and cost guides put the first mow at roughly four to six weeks. In Phoenix summer heat bermuda moves quickly once it is up; we tell you what height to look for.

Seeding itself, no. The grading before it can need one: Phoenix requires a grading permit for most grading and filling beyond shallow work, and any site disturbing an acre or more needs state construction stormwater coverage. A typical backyard lawn is under both thresholds.

Consumer guides range from about $0.07 to $0.35 a square foot for a home lawn, so a 2,000 square foot yard lands around $500 to $700 in HomeGuide's figures, and many jobs hit a $300 to $500 minimum. Prep work like ripping, grading and topsoil is added on top. Once we have measured the yard, the written quote sets your price.

You can spray it, but it will not grow until the soil warms. Extension lists May through August for seeding bermuda. For winter green, overseed ryegrass into an established bermuda lawn in October or early November instead.

Sod is instant and costs the most. Hydroseed takes about a month to establish and costs much less. If the yard needs to take dogs or play within a week, or the job is in winter, go with sod; otherwise a summer hydroseed lawn saves money.

Several short cycles a day at first so the mulch never dries out, then fewer and longer cycles once the grass is up. We leave a written schedule based on your controller and zones.

No. Hybrid bermudas are sterile and Extension notes they cannot establish a lawn from seed. They go in as sod or sprigs; hydroseed lawns use common bermuda.

Arizona requires construction general permit coverage, which includes a SWPPP, for sites disturbing one acre or more, or smaller sites in a larger common plan of development. Your engineer or general contractor prepares the plan; we install the seeding and controls it calls for.

Consumer cost guides land between about $2,000 and $4,900 an acre, with HomeAdvisor's one-acre range up to $8,700. Seed mix, mulch rate, water and access move the price. We bid each site.

Yes, for bermuda that is the right season, as long as irrigation is running. Unirrigated areas usually get hydromulch now and native seed in the fall.

It depends on the site. We price hauling water when there is no meter or hydrant access, and say so on the bid.

On gentle slopes, often yes. On steeper cut slopes or where water runs over the top, bonded fiber matrix or erosion control blankets hold much better. We decide by slope, soil and drainage area.

Before the monsoon, which the National Weather Service dates from June 15. Anything graded in spring should be covered by then.

In Phoenix, grading in or over a natural watercourse, drainageway or arroyo requires a grading permit. Check with the city before regrading near a wash; we can install the treatment shown on an approved plan.

Not bermuda. Unirrigated desert slopes do better with a native seed mix sown in fall, with hydromulch or blankets for cover until it establishes.

If the job disturbs at least an acre, or belongs to a bigger planned development, Arizona's construction general permit and your SWPPP will call for sediment controls. Smaller jobs may still need them if runoff heads to a street or neighbor.

A transportation agency 2025 rate list for erosion work puts silt fence at $378 per 100 feet for the unstabilized kind and $748 for stabilized. Phoenix pricing depends on footage, ground and access; we quote per site.

No. Silt fence is for sheet flow. Concentrated flow needs check dams, rock or a different control.

After every significant storm and on the schedule your SWPPP sets. Sediment should be removed before it builds up about a third of the fence height.

Once the site is stabilized, controls are removed and the trench lines smoothed. We can seed or hydromulch the disturbed strip.

Often not, if the work is shallow: the city exempts excavation under two feet and fill under one foot on flatter ground, up to 100 cubic yards, as long as total disturbance stays at an acre or less and no drainage course is blocked. Work near a wash, on hillside-zoned land or beyond those limits needs a permit.

Only where the surface is subsoil, rock or fill. Intact native sandy loam usually just needs ripping and amendment.

HomeAdvisor's figures run $1 to $2 a square foot to level a lawn and about $2,176 for an average reslope. Your price depends on how much dirt moves and how easy the access is.

Yes. Our grading crews handle excavation and trenching for drainage, including French drains and buried downspout lines.

October through mid-December. The seed lies dormant until fall and winter rains, then grows through January and blooms in February and March.

Only to get started if rain does not come: two to three times a week until sprouting, then about once every three to four weeks. Established stands rely on rainfall.

Over time, yes, as roots take hold. Until then, hydromulch or a blanket provides the cover. We usually combine them.

Many generic mixes contain non-native species that fail in desert heat or spread aggressively. A Sonoran native mix costs more but suits the site.
