Welcome to Hollow Oak Landscaping
A local landscape contractor, not a franchise
We design and build landscapes for homeowners in Sandwich and the surrounding Fox Valley communities. Full service means one contractor for all of it: design, hardscape construction, planting, irrigation, lighting and the seasonal maintenance that keeps it looking right.
The person who walks your property and prices the job stays with it through construction. No handoff in the middle, no guessing about who is responsible for what.
We work almost entirely within about a 30-mile radius of Sandwich, which means we know the clay, the drainage problems and the freeze-thaw cycle you are actually dealing with.

Questions
Frequently Asked
What areas do you serve?
When is the best time of year to start a landscape project?
Do you do maintenance as well as installation?
Do you charge for an estimate?
No. We come out, walk the property with you and talk through the options. If the project needs a design, we will explain what that involves and what it costs before any work begins.
Hardscape construction runs from spring through late fall, and the schedule fills up early. Planting is best in spring and fall. Winter is a good time to plan and design so the work is ready to start when the ground opens up.
Yes. Spring and fall cleanups, core aeration, fertilization and yearly maintenance programs are all in-house, and many of our clients have us on the property year-round.
