Lawn Installation and Site Grading for Platteville Properties
Four Seasons Landscaping installs sod and seeded lawns, performs site grading, and prepares new construction and renovation sites for proper drainage and a healthy lawn in Platteville, WI and southwest Wisconsin.
Lawn Installation Done Right the First Time
A new lawn installation — whether via sod or seeding — is largely determined by two factors: proper grading and quality soil preparation. Skip these steps and you're fighting drainage problems and bare spots for years. Four Seasons approaches lawn installation as a grading and soil project first, and a seeding or sodding project second.
We handle the full scope from rough grading (moving significant amounts of topsoil to establish proper drainage grades) through finish grading (final smoothing and top-dressing) to sod or seed installation. For new construction sites, we coordinate lawn installation with the builder's schedule to get quality topsoil back on the site after heavy equipment is done and the grade is set correctly.
We use grass species appropriate for Wisconsin — primarily Kentucky bluegrass, tall fescue, and perennial ryegrass blends suited to our full sun and partial shade conditions. For sod, we source locally grown product when possible to ensure the grass is acclimated to our growing conditions.

Our Process
Site Assessment
We evaluate existing grades, drainage patterns, soil quality, and sun exposure to determine the right approach for your lawn installation.
Grading & Prep
We establish proper drainage grades, import or redistribute topsoil as needed, and prepare the seedbed or sod bed with appropriate tillage and soil amendment.
Installation
Sod is laid in staggered rows with tight seams and rolled for good soil contact. Seeded areas are overseeded, raked, and starter fertilizer applied.
Establishment Care
We review watering requirements for the establishment period — critical for both sod and seed — and provide guidance on mowing timing and first-season care.
FAQ — Sod, Seeding & Grading
Sod gives you an instant lawn — you can walk on it within a few weeks and it looks established from day one. It's better for high-visibility areas, slopes (where seed would wash), and situations where you want usable lawn quickly. Seeding is more economical, gives the grass time to develop a deeper root system before establishment, and allows for more flexible species selection. For most residential lawns in Wisconsin, sod is the preferred choice for front yards and high-visibility areas; seed or hydroseeding works well for large rear yard areas where cost and time are the priorities.
The ideal windows are late spring (mid-May through June) and early fall (mid-August through September). Fall seeding is often the best option for Wisconsin — cooler temperatures and fall rains help germination without summer heat stress, and newly seeded grass establishes well before winter. Sod can be installed spring through early fall as long as watering is consistent. Avoid late-fall installation after mid-October when soil temperatures drop below the germination threshold.
New sod needs 2–3 weeks before it's rooted enough to walk on lightly, and 4–6 weeks before it's fully established and ready for regular mowing and use. During the first 2 weeks, watering is critical — the sod needs to stay consistently moist (not saturated) to encourage root development into the prepared soil below. We'll give you a detailed watering schedule based on the time of year your sod is installed.
Minor low spots can be corrected by topdressing with topsoil and overseeding. More significant drainage issues — areas that stay wet for days after rain, downspout discharge areas, low corners of the yard — often require regrading and sometimes a French drain or surface swale to move water off the problem area. We assess drainage issues during the site consultation and recommend the most effective solution for the specific situation.
Yes — grading is a standalone service. If you have a drainage problem, a slope that needs correction, or a new construction site that needs rough grading before any lawn work, we can provide grading services independently. Grading projects are estimated based on the scope of earthwork involved — volume of soil to be moved, access for equipment, and whether imported topsoil is needed.
