How it goes

From the first call to the handover

  1. Visit and measurements

    We check the subfloor, ventilation and existing plumbing before pricing anything.

  2. Material selection

    Tile, vanity, fixtures: we point you to local suppliers and order everything before demolition starts.

  3. Construction

    Demolition, plumbing, electrical, membrane, tile, finishing. Only one bathroom? We schedule to keep the days without a shower to a minimum.

  4. Final walkthrough

    We test every tap and drain with you, and clean up before we leave.

The bathrooms we redo here

Many of the bathrooms we redo date from when the house was built: 1980s and 1990s master bathrooms in Les Cèdres and Pincourt, original bathrooms in L’Île-Perrot bungalows, where the tub often gives way to a walk-in shower. In Hudson we also redo period bathrooms without losing the house’s charm.

In Saint-Lazare, a large share of homes are on wells and septic systems. Adding a bathroom may require checking the septic system’s capacity, and hard water marks tile and fixtures, so we choose finishes accordingly and rough in for a softener if you want one.

Permits, RBQ licence and warranty

What is worth checking before you sign with any bathroom renovation contractor.

  • Permits in Vaudreuil-Dorion and Saint-Lazare

    A permit is often required when plumbing moves or a wall is changed. We check with the City of Vaudreuil-Dorion, the Town of Saint-Lazare or your municipality, and prepare the paperwork with you. How long the permit takes is up to the town, not us; we file a complete application so it is not held up.

  • Schedule

    Plan for 2 to 4 weeks of work. Materials are ordered before demolition, the toilet is usually back in service each evening and the shower is out of use for about 10 days while the membrane and tile go in.

  • RBQ licence and licensed trades

    Construction 3 Lacs inc. has held general contractor licence RBQ 5788-4918-01 since 2020, bonded through the APCHQ. Plumbing and electrical are done by licensed masters that we coordinate and answer for.

  • Warranty

    At handover you get the manufacturer warranties (vanity, fixtures, heated floor) and our subcontractors’ invoices, so everything is on file if you ever need it.

Questions homeowners ask

Before starting a bathroom renovation project with us.

How long will I be without a bathroom?

Plan for 2 to 4 weeks of work. The toilet is usually put back in service each evening, and the shower is out of use for about 10 days while the membrane and tile go in.

Do I need a permit to renovate a bathroom?

If plumbing is moved or a wall is changed, most towns in Vaudreuil-Soulanges require a permit. We check with your municipality and prepare the paperwork with you.

Can I convert my tub into a walk-in shower?

Yes, it is our most common request. We keep the existing drain when possible, otherwise the plumber relocates it. Plan for a custom base and a full membrane.

Is a heated floor expensive to run?

No. A bathroom heated floor on a programmable thermostat draws very little, and it is the comfort feature clients least regret.

Do you renovate bathrooms in Saint-Lazare?

Yes, Saint-Lazare is about fifteen minutes from us. If the house is on a septic system, we check it at the visit before adding a bathroom, and we adapt the finishes to hard water if you are on a well.

How much does a bathroom renovation cost?

For a complete 50 sq ft bathroom, plan for $16,499 to $23,742 in the standard range, taxes included. Relocated plumbing and demolition are extra. The firm price is confirmed in writing after a free visit.
