David J. Frank Landscape Contracting has worked throughout Lake Country for decades. Our crews handle properties in Chenequa, Delafield, Hartland, Merton, Nashotah, Oconomowoc, Okauchee, and Pewaukee—everything from residential estates to lakefront homes to commercial sites. We know Lake Country’s soil, its lakefront challenges, and what actually grows well.

What Makes Lake Country Properties Different

Glacial activity shaped Lake Country’s terrain—rolling hills, numerous lakes, and soil that changes from one property to the next. A lakefront home in Oconomowoc faces completely different conditions than a property two miles inland in Hartland. Estates in Chenequa have different needs than compact lots elsewhere.

The lakes create their own weather patterns. Properties close to Pewaukee Lake, Nagawicka Lake, or Okauchee Lake get different wind, different humidity levels, and different frost patterns than areas farther away. After decades of working throughout the region, we’ve learned how these factors shape plant selection, watering needs, and maintenance timing.

Residential Landscaping Throughout Lake Country

Design-Build Projects for Lake Country Homes

Our residential design-build services cover complete property transformations. Renovating a lakefront estate in Oconomowoc? Building outdoor living areas in Delafield? One team handles everything: design, planning, and construction.

Hardscape projects make up much of our Lake Country work—paver patios that handle Wisconsin’s brutal freeze-thaw cycles, outdoor kitchens with everything needed for cooking and eating outside, fire pits that let you stay out when it gets chilly, retaining walls for hillside properties, walkways made from natural stone or pavers, water features that fit lakefront settings.

Base work matters more than most people realize. Proper excavation, solid base layers, good drainage—skip any of this and the project fails within a few seasons. We don’t cut corners on the unglamorous stuff that nobody sees.

Special Landscaping Needs for Lakefront Homes

Lakefront sites usually need solutions for slopes, preventing erosion, and making the most of water views. Properties away from lakes might prioritize privacy screens, spaces for entertaining, or creating distinct outdoor zones. Our landscape architects build plans around your actual site conditions and how you’ll use the space.

We also install and renovate:

• Walkways to and from the lake 

• Retaining walls 

• Shoreline riprap

Professional Lawn Care for Lake Country Properties

Lawns across Lake Country vary dramatically. Sandy soil near lakes drains quickly and requires a different approach. Heavier clay further inland requires a different approach. Our lawn care programs get adjusted based on what your property actually has:

• Fertilization: Timing matches when grass actually grows, and rates depend on what’s in your soil
• Weed Control: Barriers go down in spring to stop seeds from sprouting; spot treatments knock out anything that gets through
• Core Aeration: Punches through compacted ground so roots can push deeper
• Overseeding: Brings in better grass types that fill in bare spots and handle dry weather

A sunny Hartland lawn with loose soil needs completely different care than a shaded Merton yard with clay.

Tree Care From Certified Arborists

Mature trees show up throughout Lake Country—oaks, maples, and others worth significant money that define how neighborhoods look. Our certified arborists keep them healthy through winter pruning (best for most trees), spotting disease early, treating pest problems, and removing trees safely when needed.

Planting new trees requires picking species that match your conditions—how much sun the spot gets, what kind of soil you have, how much space exists, and how big the tree will eventually get. We plant them right and get them established so they actually thrive instead of barely hanging on.

Maintenance and Seasonal Services

Regular maintenance keeps Lake Country properties looking good—cutting grass, trimming, edging, mulching, pruning, spring and fall cleanups. We stick to consistent schedules throughout Delafield, Pewaukee, Oconomowoc, and the surrounding areas.

Seasonal color changes with the calendar—bulbs and pansies when spring arrives, petunias and geraniums through summer heat, mums and kale when fall comes. We prep soil, keep everything looking good while it’s growing, and pull plants out when it’s time to switch.

Automated irrigation systems take guesswork out of watering. We figure out proper coverage, put in complete systems with smart controllers, turn them on each spring, fix problems through summer, and drain everything before winter. The controllers respond to actual weather and soil moisture instead of just running on a timer.

Outdoor lighting lets you use outdoor spaces longer while making things safer. Path lights show the way. Uplights show off lovely trees and building features. Downlights create softer overall lighting.

Our holiday decorating service runs throughout the year. Popular holidays include Easter, Fourth of July, Halloween, and Christmas. We design displays that fit your home, install everything safely, maintain it all season, take it all down, and can store decorations if you want.

Commercial Landscaping in Lake Country

Commercial Property Maintenance

Commercial sites throughout Lake Country need maintenance that keeps them looking professional:

• Mowing and Trimming: Regular cuts keep turf neat
• Bed Maintenance: New mulch, pulling weeds, pruning plants
• Seasonal Cleanups: Thorough spring and fall work
• Quality Checks: We walk properties regularly to spot problems

Most contracts run April through November. Construction work happens all year.

Design-Build and Snow Removal

We do both design-build work and bid-build projects across Lake Country. Outdoor spaces we create—courtyards, employee areas—get used because we design them thinking about real conditions.

Wisconsin winters need dependable snow management. We run crews 24/7 when storms hit, keeping businesses in Oconomowoc, Hartland, Nashotah, and everywhere else accessible.

Commercial Irrigation and Holiday Displays

Commercial irrigation needs smart design to cover ground efficiently. We install full systems with controllers that respond to weather, handle spring startup and fall shutdown, and fix problems all season.

Holiday decorations for businesses need to look inviting while fitting your brand. We install, check regularly, and remove everything when the holidays end. Storage available if you want it.

Specialty Services

Our interiorscape work puts plants in Lake Country offices and commercial buildings. Research shows that indoor plants reduce stress, improve air quality, and help people get more done. We evaluate spaces, pick plants that’ll work, install them, maintain them, rotate seasonally, and replace any that struggle.
