Grading is one of the most essential parts of landscaping hence it needs to be done correctly from the very start. With our qualified crews, we will ensure your grading is done to code and that it will protect your home.

We can accommodate all yards, from small ones – with nearly no access – to large ones, like acreages. Whether your property is new or infill, we have the skills and the equipment to properly grade your yard the first time around.


In some cases, it can be difficult to ensure proper drainage through grading alone. A weeping tile, trench drain or other component may be useful to ensure the water ends up in the right places!


  • Downspouts are connected, in good shape and discharged to the ground surface past the excavation zone and within the property.
  • Positive slopes exist away from foundation walls.
  • Drainage swales convey surface drainage off the lot without impacting adjacent properties.
  • Settlement under steps or decks is properly backfilled.
  • Window wells are debris-free to ensure effective drainage.
  • Ensure that your sump pump discharge and downspouts direct water away from the house.
  • Keep material from building up in swales creating dams.

Frequently Asked Questions

  • Q: What is rough grade?
    A: On a new home, the rough grade is a soil elevation achieved by the homebuilder to return the clay to a level compliant with the developments grading plan; it also includes correctly installed downspouts, eaves troughs and window wells among many other things. On an existing home, the rough grade includes removing current materials to approximately 4” below the final grade elevation.
  • Q: What is final grade?
    A: On a new home, final grade involves increasing the elevation of your property through the addition of soil to comply with the development’s drainage plan. This typically means adding 4” to 6” of soil to the rough grade. Most building authorities require an inspection and approval of final grade elevations.
    A: On an existing home, final grade is the addition of 4” to 6” of soil while ensuring the elevation along the property line is returned to its pre-existing elevation and that positive drainage is maintained throughout the property.
  • Q: How do I get final grade approval on a new home?
    A: Greentree will have an engineer survey the site and provide a final grade certificate to the local building authority for approval. Some municipalities may charge an inspection fee that is not covered by Greentree.
  • Q: How long does it take to receive final grade approval?
    A: There can be quite a variance in the timeline: less than a month would considered quick, and rarely would it take more than 3 months from when we arrive on your site! Unfortunately, it is mostly a matter of waiting for approval once we leave so there will be little activity on your property.
  • Q: What is expected from me while we wait for final grade approval?
    A: The grading has a tolerance of 4 cm. Therefore, we request that no major activities occur within your yard that may change the grading elevations (fence, deck, shed, or other construction). Do not drive or tow anything across the soil as it will leave ruts. As well, fresh topsoil proficiently grows weeds: we ask that you remove any weeds larger than 3 cm.
  • Q: What happens if my final grade approval fails?
    A: It is not uncommon for the approval to fail the first time. Greentree will correct deficiencies related to our workmanship and re-apply as soon as possible at no extra charge. However, some deficiencies may not be related to our workmanship and would form an extra charge or may be covered by your builder (i.e. eavestroughs, sheds and window wells). Most municipalities will notify us by email but some may leave a report at the home; if this is the case for you, please send us a copy!
  • Q: Does my infill home need final grade approval?
    A: Yes, on top of final grade approval you’ll also require a Drainage Plan to be submitted and approved by the city. The drainage plan will look at the drainage of your lot, but also ensure that your water won’t affect your neighbors drainage.
