Why Final Grade Matters
Final grading in Grande Prairie directs water away from the foundation and creates a smooth, level surface for sod installation.
Poor grading leads to water pooling against foundations, uneven lawns, and failed sod installations. In Grande Prairie, water pooling against a foundation through freeze-thaw cycles can contribute to cracking, heaving and basement leaks. Getting the grade right from the start prevents all of this.
Laser-guided grading ensures consistent drainage slopes away from the foundation: critical for preventing water damage in freeze-thaw climates.
Don't Lose Your Deposit
Many builders hold a landscaping deposit that's released after you complete final grading and landscaping. Missing the deadline means forfeiting your deposit. Book early: the spring rush fills fast and late bookings risk not completing before fall freeze-up.
Our Grading Process
We use laser-guided compact track loaders to achieve precise, consistent grade across your entire lot. The minimum standard is 2% slope away from the foundation on all sides, but we also consider neighbouring lot drainage, easements, and any low spots identified during our initial survey. Every lot is different: cookie-cutter grading doesn't work in variable soil conditions.

Common Grading Problems We Fix
Many homes, even relatively new ones, have grading issues. Builders often leave rough grades that settle unevenly after the first winter. Clay soils common expand and contract with moisture, causing grade to shift over time. We see these problems repeatedly:
- Water pooling against foundation walls: visible after rain or spring melt
- Negative grade (sloping toward house) on one or more sides
- Settlement depressions along foundation where backfill has compacted
- Neighbour drainage flowing onto your lot through poorly planned swales
- Failed sod from previous poor grading: dead spots, pooling, and uneven lawn
New Build Packages
We offer combined final grade + sod installation packages for new builds in subdivisions. One contractor, one timeline, one invoice, and your deposit released faster.
Re-Grade Service
Existing property with drainage issues? We re-grade established yards to fix pooling, correct settlement, and restore proper drainage, without tearing out more lawn than necessary. Targeted fixes save money vs. full re-grade.

Frequently asked questions
What is a final grade and why do I need one?
A final grade by PWW Services in Grande Prairie ensures proper drainage away from your home's foundation and meets municipal grading requirements. PWW Services corrects rough grades in Grande Prairie before landscaping is installed.
When is the best time to do final grading?
PWW Services schedules final grading in Grande Prairie from May through September when the ground is thawed and workable. In cold-climate, frost can return as early as September, so earlier is better to allow time for sod installation before freeze-up.

Do I need a grading certificate from the city?
