DoorNtriM: doors, moldings, and finishing, installed straight and precise

DoorNtriM is our division dedicated to interior finishing: installing and replacing interior doors, putting up moldings, baseboards, and door/window casings. It's everything that dresses up a room and gives it character — the details we notice every day without always realizing it, but that we spot right away when they're poorly done.

Finishing is a craft of precision. A door that drags, a molding with mitre joints that gape, a baseboard that waves along a crooked wall: it shows, and it takes value away from a nice room. Our finishers install straight and precise, set the gaps just right, and take care with the corners. The result is flawless, ready to paint, with that clean finish that makes it look like everything was always there.

As everywhere at Beau-frère à louer, you get guaranteed work, an insured and RBQ-licensed team, and a firm project price confirmed before we start. No hourly billing that keeps stretching: you know what it'll cost before the first nail goes in. Request your quote and we'll get back to you with a clear price for your project.

Frequently asked questions

What people often ask us

Do you install interior doors?

Yes. We install all kinds of interior doors: pre-hung doors in their frame, closet doors, sliding or French doors. We take care of the casing, adjusting the gaps, and installing the hardware so the door opens and closes perfectly. The result is straight, plumb, and ready to paint.

Do you replace an existing door?

Yes, it's a very common request. We remove the old door, check the condition of the frame, and install the new one while adjusting the gaps and hardware. If the frame is still good, we can often just change the door; if it's damaged or out of square, we'll tell you and suggest redoing the casing if needed.

Do you put up moldings and baseboards?

Yes, that's the heart of our finishing division. We install moldings, baseboards, quarter-round, and decorative trim, with tight mitre joints and precise cuts. We follow the movements of the wall and floor for a clean result, with no visible gaps, ready to paint.

What about door and window casings?

Yes. We install and replace casings (the framing trim) around doors and windows. It's often what makes the difference between a finish that's just okay and one that has character. We adjust the mitres, shim the trim straight, and take care with every corner.

How does a quote work?

You describe your project to us — number of doors, length of moldings and baseboards, casings to redo — by phone or through the online form. We assess the scope of the work and the materials, then get back to you with a firm project price, confirmed before the work begins. No surprises on the bill.

How long does it take to install a door?

It depends on the type of door and the condition of the frame, but a standard interior door is usually installed in a few hours. If we have to redo the casing or adjust an opening that's out of square, it takes a little longer. We give you an idea of the timeline in your quote.

Do I have to supply the door and materials?

Whatever you prefer. We can supply the doors, moldings, baseboards, and casings based on your choices, or install the ones you've already bought. For doors, it's often a matter of style and budget; we talk it over beforehand to make sure everything's compatible and to avoid back-and-forth trips. It's spelled out in the quote.

Are you insured and RBQ-licensed?

Yes. Beau-frère à louer is insured and holds a licence from the Régie du bâtiment du Québec (RBQ). Our finishers work in uniform and every job is guaranteed. You get professional service, with a firm project price announced before we start.
