What we do

Landscaping services for Cornwall & SD&G properties

Most landscapers in Cornwall lead with grass cutting. We lead with the grade, because a yard that drains is the only thing everything else sits on.

Grading & Drainage Correction

If water sits against the house, pools in the middle of the lawn or runs into the garage, the grade is wrong. We re-shape the yard with the laser, build swales, install drain lines and catch basins, and extend downspouts past the new work. Cornwall clay does not absorb water, so it has to be given somewhere to go.

Sod Installation & Lawn Renewal

Fresh sod lawn over prepared topsoil, not laid on top of whatever was already there. We strip the old lawn, correct the grade, screen and place quality topsoil, then lay tight-jointed rolls and roll them in. Includes a watering schedule so it roots instead of going brown in six weeks.

Garden & Flower Bed Design and Planting

Flower bed planting laid out for how the front of your house actually reads from the street: trees, shrubs and perennials sized for their mature spread, crisp paver or steel edging, and clean soil depth. Built to look intentional in year one and better in year five.

Seasonal Cleanups (spring & fall)

Spring and fall yard cleanup: leaves, winter sand and debris off the lawn and beds, cut-backs, edge redefinition, gutters clear of the roofline debris and everything hauled away. The fastest way to make a tired property look maintained again.

Not sure where to start? We'll walk the property and tell you what to do first.

The part nobody quotes on

Why your yard floods every spring

If there is standing water on the lawn in April, no amount of sod, mulch or river rock will fix it. Here is what is actually happening.

The grade, not the grass, is the problem

Ground should fall roughly 2% away from the foundation for the first two metres, then keep running to somewhere it can leave. Most Cornwall yards that flood are close to flat, or they slope back toward the house after years of settling and added topsoil. Sod laid over that grade floats on the same puddle it did last spring.

Eastern Ontario clay does not drain

Our soil holds water instead of absorbing it, and in March it is holding water on top of ground that is still frozen. That is why the yard is a pond for three weeks even though nobody has watered it. Water has to be moved by shape and by pipe, not left to soak in.

Where the water goes

Depending on the lot: a shallow swale to carry surface water around the house, a catch basin tied to a solid line running to daylight, weeping tile and clear stone in the wet corner, downspouts extended past the beds, and window wells kept above grade. We set all of it with a laser level before any topsoil or sod goes down.

We check the grade at every estimate, even if you called about a flower bed. If it is fine, we say so.

Hiring the wrong contractor costs more than hiring the right one.

A redo on landscaping costs more than doing it right the first time. Here is the difference.

What usually goes wrong

  • Sod that greens up for a month, then thins and dies by mid-summer because it was rolled out over compacted clay with no topsoil
  • Beds that look sharp on handover and are overrun with weeds and outgrown plants by year two
  • Drainage that never actually got fixed, so the yard floods again the next spring
  • Equipment ruts and a torn-up lawn along the access route, left for you to repair
  • A crew that finishes, cashes the cheque and stops answering the phone

How we work on landscaping

  • Grade corrected and quality screened topsoil placed to depth before a single roll of sod goes down, with a written watering schedule so it roots
  • Plants specified by mature size with proper soil depth, edging and mulch, so beds stay readable instead of closing in
  • Drainage designed with a laser level: swales, catch basins, drain lines and downspout extensions, shown on your written quote
  • Our own machines and access mats, and lawn repair along the access route is part of the scope, not an extra
  • Written workmanship warranty ([WARRANTY TERM]) and a real local number: Tristan answers it

What you get in writing

  • Workmanship warranty in writing
