Glass and thermos repair in Terrebonne
On the North Shore, people tend to search for the job rather than the town: a thermos on the Rive-Nord, a patio door on the Rive-Nord. Terrebonne is off the island, with its own city rules and outside Montréal's RénoPlex program, so this page sticks to what applies here. We're a free referral service. Tell us the job and your address, and we'll check whether an independent pro who works in Terrebonne can take it. If no one covers it, we'll say so rather than leave you waiting.

On the North Shore, the search starts with the thermos
'Thermos Rive-Nord' is a common search on the North Shore: the fog comes first, the town second. A thermos is the sealed glass unit in the window, two or more panes sealed together around a spacer. When the seal lets moist air in, a haze forms between the panes that can't be wiped from either side.
Condensation you can wipe off the room side, usually on cold winter mornings, is a different matter. That is indoor humidity meeting cold glass, and the fix is less moisture in the house, not new glass. If your fog is between the panes, our thermos page explains each option.
Fix the glass before changing the window
When one thermos fogs, the frame around it is often still in good shape. In that case the pro measures the glass, a new unit is made to size, and it goes into the existing window. The house looks the same afterwards, and nothing else is disturbed.
Replacing the window is the better decision when the frame is rotten or warped, when the window leaks air all the way round, or when so many units have failed that glass alone no longer makes sense. The same logic applies to a cracked or broken pane: in most frames that's a glass job, not a window job. A good pro will tell you which case you're in, and why.
Patio doors and screens
- Patio door repair: a door that won't lock, drags on its track or lets cold in at the sill usually needs rollers, a lock or weatherstripping.
- Patio door glass: a fogged or cracked panel is replaced as a thermos, and the door stays in its frame.
- Screens: torn mesh on a window or patio-door screen is rescreened in the existing frame.
- A new patio door: when the frame is damaged or out of square, after checking with the City.
Rénoclimat: what qualifies outside Montréal
RénoPlex, the Ville de Montréal's renovation program, is limited to buildings on Montréal's territory, so it doesn't reach Terrebonne, Laval or other off-island cities. Rénoclimat is provincial and does. To qualify, the new door or window has to be ENERGY STAR certified and installed in the existing rough opening, the home needs an energy evaluation before the work and another after, and its EnerGuide rating must improve.
Replacing only the glass, a sash, or a door without its frame doesn't qualify, so a thermos repair isn't covered. A complete replacement may be. Read our subsidy guide before booking the first evaluation, since its timing matters.
Permits: ask the Ville de Terrebonne
Terrebonne issues its own permits, and we haven't verified its rules for replacing windows or doors. Before you sign for new windows or a new patio door, ask the City what it needs. A thermos swap or a roller repair is a much smaller job, but if you're unsure, one question to the City settles it.
When the pro quotes, ask for their RBQ licence number. Window and door contractors in Quebec need one, and licensed contractors must show it on their quotes and promotion.
Terrebonne questions
Do you find pros in Terrebonne?
Often, but we check each request rather than promise it. Terrebonne is off the island, and coverage depends on which independent pros take North Shore work for your kind of job. Send your address, a photo and a line on what's wrong. If a pro can take it, we pass it on and follow up; if not, we tell you plainly. The service areas page shows where pros work regularly.
Is a thermos replacement subsidized in Terrebonne?
No. Rénoclimat, the provincial program that applies in Terrebonne, covers complete ENERGY STAR windows and doors installed in the existing openings, with energy evaluations before and after. Replacing only the glass or a sash doesn't qualify. Montréal's RénoPlex doesn't apply off the island at all. A thermos swap is still often the less disruptive fix; our thermos page explains when it fits.
Do I need a permit in Terrebonne to change windows?
Ask the Ville de Terrebonne before you order. The City sets its own rules, and we haven't verified them for window or door replacement. Patio doors and any change to the size of an opening deserve extra care, since those always need a permit on the island. A detailed written quote from the pro gives the City what it needs to answer.
Thermos repair on the North Shore: how does it work?
Usually in two visits. The pro measures the fogged glass, orders a thermos made to those measurements, and returns to fit it in your existing frame. Because each unit is made to order, it isn't same-day work, so ask how long the order takes. Photos of the whole window and the fogged area, with rough measurements, help the first quote.
Patio door repair on the North Shore?
Yes, and it's often a repair rather than a new door. Rollers wear, tracks bend, locks stop catching and weatherstripping flattens, and each can be replaced on its own. A new door makes sense when the frame is damaged or out of square. Mention whether it's a sliding or hinged door, and attach a photo of the track or lock.
