Frequently Asked Questions

For the cool-season grasses that grow here, late summer to early fall is the main window, roughly late August through September, with some October work in warm spots. Spring is the second choice; it works, but weeds compete harder and summer heat arrives quickly.

Yes, if the lawn is thin rather than solid. We mow it short, rake or core-aerate so the slurry reaches soil, and spray over it. Where the lawn is mostly weeds or dead patches, we usually recommend a full renovation with grading and new topsoil first.

You do not get an instant lawn the way you do with sod, and the area needs steady watering for about three weeks while seed germinates. The slurry can also stain siding or concrete if it is not masked or rinsed, which is why we protect edges as we spray.

National cost guides put residential hydroseeding somewhere between $0.07 and $0.35 per sq ft, and HomeGuide adds that most outfits set a job minimum, typically $300 to $500 or higher. Grading and topsoil are billed on top. Once we have walked the yard we write down one figure, and that signed figure is your bill.

In warm soil, hydroseeded grass generally shows in five to seven days; Angi's figure is that most hydroseeded lawns are up within 7 to 14 days. Plan on the first cut roughly four to six weeks out, when the blades reach about 4 inches.

Most short banks hold well with a heavier mulch rate and tackifier. On very steep or long slopes we add a blanket, or spray a bonded fiber matrix, to keep seed and soil on the hill through heavy rain.

Usually. The hose runs from the truck parked on the street, so we can spray behind a house or down a narrow side yard without driving equipment over the lawn.

HomeGuide's figures are roughly $1,000 to $1,750 for a 5,000-square-foot lawn and $1,900 to $2,800 for a quarter acre. Loam, grading and stone removal come on top. The number on your signed quote is the real price.

Once it fills in, it holds up just as well, and it is often rooted deeper because it grew in your own soil. Sod gives an instant look; hydroseed takes about six weeks to fill in but costs a fraction as much.

Keep off it except to move hoses until after the first or second mow. Early foot traffic crushes seedlings and leaves bare paths.

The dye shows where the slurry landed, so coverage is even. It fades within a few days of sun and rain.

The tackifier and fiber mulch are made to hold through normal rain. A severe downpour on a slope can move some slurry; we check and touch up thin spots.

Yes. Most of our commercial seeding is done for builders, site contractors and property managers, scheduled around their grading.

Yes. If the plan names a mix and rate, we source that mix and apply it at the specified rate.

We apply a heavier mulch layer, often with a cover crop, to hold the soil over winter, then overseed with the permanent mix in spring.

A single tank load covers thousands of square feet, so a few acres is typically a one- or two-day job once grade is ready, depending on access and water supply.

Short, moderate banks usually hold with a heavier hydromulch rate. Steep or long slopes, and anywhere water flows across the surface, generally need a blanket or bonded fiber matrix.

No. Straw and coir blankets rot away on the slope as the grass grows up through them. Some contain plastic netting; we can use natural-netting products near areas where wildlife or mowing are a concern.

It is sprayed mulch with a much stronger binder, so it cures into a single porous crust over the soil. It protects seed on steep ground where a blanket is hard to install.

Yes. We fill the gullies, regrade the face, deal with the water source, and then seed and cover it.

If soil could wash onto the street, a neighbor's yard or a storm drain, a short run of fence and inlet protection is cheap insurance. Larger projects usually have controls required by their approved plan.

Until the disturbed area is stabilized, which usually means grass is established or a permanent cover is in place. Then it comes out.

Where a trench is not possible, we use weighted or staked alternatives such as fiber socks so there is no gap.

Yes, as a scheduled maintenance visit. We remove built-up sediment, re-set stakes and replace damaged sections.

Most lawns do well with several inches of good topsoil. We probe the yard and calculate the yardage needed to bring thin areas up to that depth, then list it on the estimate.

Usually. We reshape the yard so it pitches away from the walls, and where that is not enough we add a trench drain or carry the downspouts farther out.

Yes. Stones, brick and construction debris raked out of the yard are hauled off as part of the job.

We use compact equipment where it fits and hand work where it does not. Access affects the price, so we look at it during the visit.

Yes, for thin lawns. We mow short and aerate so the slurry reaches soil. If the lawn is mostly weeds, a renovation works better.

Late August through September is best for cool-season grass. Spring works for small repairs, but seedlings have less time before summer heat.

A thicker lawn crowds weeds out over time, but it does not kill them. Heavy weed cover usually calls for a renovation.

Wait until new grass reaches about four inches, typically several weeks after seeding, and mow with a sharp blade.
