What we do in Sainte-Thérèse

Altitude Services is an excavation and landscaping contractor based in Laval, serving Sainte-Thérèse and its sectors: downtown, the train station area, the streets around Boulevard Labelle and the older neighbourhoods toward Boisbriand. The owner, Jonathan, comes to see your property himself, writes the quote and runs the machine on the day of the work.

The ground in Sainte-Thérèse

Sainte-Thérèse is a town of 1960s and 70s bungalows on narrow lots. Access is usually the first question: a 6 foot gap between two houses, a fence, a cedar hedge. That is exactly why we work with a compact mini excavator and loader, and with ground protection mats so we leave no marks on the lawn or the neighbour's driveway. Foundation drains from that era are also reaching the end of their life.

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.

Frequently asked in Sainte-Thérèse

Do you really travel to Sainte-Thérèse?

Yes. Our base is in Sainte-Dorothée (Laval), about 15 minutes from Sainte-Thérèse. We go regularly and group our jobs by area to keep travel costs low. For a small half-day job, we try to pair it with another job nearby the same week.

Do I need a permit from the City of Sainte-Thérèse?

For grading, sod, a drain or pavers on your own property, usually not. A retaining wall, a connected dry well or work touching the street right-of-way may require one. We tell you in the quote, and we can point you to what to ask the Sainte-Thérèse planning department.

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, not a two-month window.

Also nearby

We also serve the neighbouring towns: Terrebonne, Mascouche, Blainville, Boisbriand, Repentigny, plus Laval and all its sectors. See every town in Greater Montreal.
