Windows & Doors in Dalkeith: Country Living in North Glengarry

Dalkeith is a hamlet that saved its own library, keeps its 1867 general store as a history centre, and still answers to the rhythm of the farms around it. It is also the kind of place where a window company from the city rarely bothers to send a truck. Unisson does. From our factory in Saint-Laurent, about 115 km away, we now measure, build, deliver and install windows and doors in Dalkeith and across the old Lochiel township, with our own crews and in both official languages.

Why Unisson now serves Dalkeith, and what factory-direct means on a concession road

Dalkeith sits on County Road 23 in the northeast corner of North Glengarry, roughly between Alexandria and Vankleek Hill, with Sainte-Anne-de-Prescott and the Quebec line a few minutes to the east. It began as Robertson's Mills on the little river the settlers called the De Graisse, was renamed Dalkeith in the 1860s, and has stayed a compact farming hamlet ever since. When the county library closed the Dalkeith branch in 2016, residents reopened it themselves as a volunteer library and community space; that tells you most of what you need to know about the place.

Unisson's expansion into eastern Ontario in 2026 was built around exactly this kind of community. Our service territory now runs the Ottawa River corridor from Hawkesbury to Ottawa and south through Glengarry to Lancaster, and Dalkeith is on the direct line between Hawkesbury and Alexandria that our trucks travel anyway. Being a manufacturer changes the economics of serving a hamlet: there is no showroom overhead to recover, no dealer margin, and no subcontracted installer. The windows are built in our Saint-Laurent factory to your measurements and installed by our own people.

For a Dalkeith homeowner that translates into a made-to-measure product for openings that were framed by hand in 1890, one company responsible for both the window and the installation under one written warranty, and an estimator who comes to the farm at no charge and speaks whichever language the household prefers. Lochiel has always been a mix of Highland Scots and French Canadians, and our crews are comfortable in both.

Dalkeith homes: farmhouses, hamlet lots and the wear of an open-country winter

Housing around Dalkeith is dominated by the farm. On the concessions and side roads you find the two-storey farmhouse in brick or clapboard, often with the centre gable and tall narrow windows of the Ontario pattern books, built between the 1870s and the 1920s. In the hamlet itself, along County Road 23 and Dalkeith Road, there are storey-and-a-half frame homes from the same era, a few post-war bungalows, and the odd converted schoolhouse or church. Since the 1980s, severed farm lots have added newer bungalows and two-storeys, many of which are now on their original, tired builder-grade windows.

The failures follow the age of the home. In the century farmhouses, the original wood double-hungs have rotted at the sill and the meeting rail, the sash cords are gone, and the storm windows that once made them bearable are stacked in the shed. Where a previous owner installed vinyl replacements in the 1990s, the sealed units have fogged and the corner welds have cracked from the thermal cycling. On the newer homes, builder-grade double-glazed sliders are approaching thirty years, which is past the design life of their seals. Entry doors on nearly all of them face open fields and leak at the threshold.

The climate is unforgiving. Dalkeith lies in flat, open farmland with long fetch for the wind, and winter nights in the minus twenties are ordinary; cold snaps flirt with minus 30. Freeze-thaw cycles in March and November push meltwater into every crack and freeze it overnight. Humidity is a quieter enemy: farm kitchens, wood stoves and older homes with limited ventilation put a lot of moisture on cold glass, and condensation on a single-pane or failed unit ends as mould on the sill.

• Century farmhouses: sill and rail rot, no flashing, storms in the shed
• 1990s vinyl replacements: fogged sealed units, cracked corners, drafts
• 1980s-2000s bungalows: builder-grade sliders at end of seal life

Which products fit Dalkeith homes

For an exposed farmhouse, our recommendation is triple-glazed UPVC windows in casement or awning form. Casements compress against the frame with a multi-point lock and give the tightest seal against wind; awnings suit the small openings over a kitchen sink or in a bathroom. UPVC never needs paint, does not rot, and keeps its seal through freeze-thaw, all of which matter on a property where the barn already takes the maintenance hours. For tall, narrow century openings we build to the exact dimensions rather than shrinking the glass with fillers.

If the farmhouse is brick or has a painted exterior worth respecting, our hybrid windows put an aluminum-clad exterior in your chosen colour over a UPVC core, keeping the look of painted wood without the upkeep. Every window we produce is ENERGY STAR certified under Canada's single national specification, in force since 2020: a U-factor of 1.22 W/m²·K or lower, or an Energy Rating of 34 or higher. Our triple-glazed units with argon fill and low-E coatings exceed those numbers comfortably, which on a farm heated with propane or oil is money you notice.

Doors are the other half of the job. Our insulated steel and fibreglass entry doors have a thermal break, multi-point locking and an adjustable threshold that actually seals against a field wind. Patio doors, whether sliding or swing, are built as single factory assemblies with triple glazing and a low-profile drained sill. All of them are ENERGY STAR certified, and all are measured by the same estimator who measures your windows.

• Triple-glazed UPVC casements and awnings: tightest seal for open farmland
• Hybrid aluminum-UPVC: colour-matched exteriors for brick and painted farmhouses
• Entry and patio doors: insulated, multi-point locks, sealed thresholds

Ontario specifics: building code, rebates and permits in North Glengarry

Dalkeith is in the Township of North Glengarry, which applies the Ontario Building Code; the 2024 edition has been in force since January 2025. For replacement windows the code questions are limited: a bedroom window that serves as an emergency exit must retain the required clear opening after replacement, and any new or enlarged opening must meet structural and energy rules. Our units are specified above the SB-12 energy requirements Ontario sets for new houses, so a Unisson replacement leaves the home ahead of the code rather than merely compliant.

As of late summer 2026, the rebate picture is this: the federal Greener Homes grant and loan are closed to new applications, and Ontario has not yet joined the federal Greener Homes Affordability Program. Ontario's active program is the Home Renovation Savings Program from Save on Energy and Enbridge Gas, which has been offering a fixed rebate per eligible ENERGY STAR window or door opening, typically with a minimum number of openings and, on some paths, alongside another upgrade such as attic insulation. Homes heated with propane, oil, wood or electricity have qualified as well as gas customers, which is relevant in a hamlet without gas service. Terms change, so confirm on the program site; we supply the ENERGY STAR documentation.

Permits in North Glengarry are simple: the township's guidance is that a same-size replacement of a window or door needs no building permit, while changing the size of an opening does. Farmhouse projects often involve enlarging a kitchen window or adding a patio door; we flag those at the estimate so you can confirm with the township office in Alexandria before anything is built.

• Same-size replacement: no permit per North Glengarry guidance; enlarged or new openings need one
• Egress: bedroom exit windows keep their clear opening
• Rebates: propane, oil, wood and electric heat have qualified; verify current terms

How it works from Montréal: measure, build, deliver, install

It starts with a free in-home estimate: our estimator drives to Dalkeith, measures every opening, checks sills and framing, and leaves a written, itemized quote with no obligation. Many rural clients phase a farmhouse over two seasons, starting with the north and west sides; that is fine with us. Once approved, your windows are built at our Saint-Laurent factory to the measured dimensions. Typical lead time is four to eight weeks, longer at the spring peak, so ordering in early autumn generally means installation before hard frost.

Delivery and installation are done by Unisson crews, not a subcontractor. Dalkeith is about an hour and a quarter from the factory by Highway 40 and the 417 through Hawkesbury, so the crew arrives with your units in the morning. A typical farmhouse of ten to fourteen windows takes two to three days; we remove the old units, repair minor sill damage, insulate every perimeter with low-expansion foam, flash and seal, trim and clean up. Winter installations proceed one opening at a time so the house is never open to the wind.

Unisson backs its installations for 10 years, in addition to the manufacturer's warranty we provide on the windows and doors themselves, and because one company did both, a claim is one phone call. Financing is available for Ontario clients, which lets a whole-farmhouse project happen in one season instead of being spread over several.

• Free estimate: in-home measurement and written quote, English or French
• Factory build: Saint-Laurent, typically 4 to 8 weeks
• Unisson crews: delivery, installation and cleanup, year-round
• Warranty and financing: 10-year installation warranty; monthly plans available
