What we do in Saint-Eustache
Altitude Services is an excavation and landscaping contractor based in Laval, serving Saint-Eustache and its sectors: Old Saint-Eustache, the streets near the Rivière du Chêne and the neighbourhoods north of Highway 640. The owner, Jonathan, comes to see your property himself, writes the quote and runs the machine on the day of the work.
- Drainage and French drains: grade correction, French drain down to the footing, surface drains, dry wells where the soil allows.
- Excavation and grading: trenching, compacted backfill and fill, stump removal, site preparation.
- Pavers: new installation and relevelling of sunken pavers.
- Site preparation with the Harley Rake: crust broken, rocks removed, finish ready for seed or sod.
- Mechanized sweeping for business and condo parking lots.
The ground in Saint-Eustache
Saint-Eustache is 15 minutes from our base. The city borders the Rivière des Mille Îles and the Lac des Deux Montagnes, and several streets lie in a flood zone.
Whatever the sector, the method is the same: we first look at where the water can exit, we measure the yard (3D survey when the slope is at stake), and we give you a line-by-line quote. No vague package, no surprise at the end.



How it works
- You text us photos at 514 775-1988, or request a callback below. Often we can already tell you whether it is worth a visit.
- Jonathan comes to your place in Saint-Eustache, looks at the yard with you and sends a written quote, normally within 24 hours.
- We do the work with our own machinery, ground protection mats, and leave you a clean yard. Work guaranteed 1 year in writing.

Frequently asked in Saint-Eustache
Do you really travel to Saint-Eustache?
Yes. Our base is in Sainte-Dorothée (Laval), about 15 minutes from Saint-Eustache. We go regularly and group our jobs by area to keep travel costs low.
Do I need a permit from the City of Saint-Eustache?
For grading, sod, a drain or pavers on your own property, usually not. A retaining wall, a driveway widening or work touching the street right-of-way may require one. We tell you in the quote.
How soon can you come?
An assessment visit normally happens within the week. For the work itself it depends on the season: a few days in spring and fall for urgent drainage, two to three weeks in mid summer. We give you a real date.
