Garage doors in St. Marys

The approval comes before the order

St. Marys is a single-tier municipality, inside Perth County for census purposes and outside its government, so a door here answers to the Town's own rules, and for two sets of properties the Town has written those rules down. The Heritage Conservation District Plan puts repair or replacement of windows and doors on the list of work needing a heritage permit, alongside new construction, structural alterations, alterations to downtown storefronts and demolition. And the Plan is blunt about sequence. Without heritage compliance, the building permit cannot be issued. Where a proposal is straightforward and needs no building permit, the Plan promises a consultation with the district advisory committee inside five business days and allows an expedited permit. Applications go through the Town's Heritage Permit Application.

Which side of the street the district stops on

The boundary runs down the middle of streets rather than around blocks, so two neighbours facing each other can sit under different rules. Trout Creek and the Thames close it off to the north and west. To the east it follows the west side of Peel Street as far as Elgin, and to the south the north side of Elgin Street from Peel to the river. Properties on the eastern side of Peel and the southern side of Elgin are outside it. The district is not the whole of it: the Town counts 48 individually designated properties, some inside the district and the rest spread through the town. More than a hundred others sit on the Municipal Register as non-designated, which means no heritage permit and no committee review, but sixty days of written notice before any building on the property comes down.

A door cut to the opening, not the opening cut to the door

Of 3,130 occupied dwellings in a town of 7,386 people, 1,175 date from 1960 or before. That is 37.5 per cent of the stock. On houses that old the garage is often younger than the house and narrower than a catalogue expects, and where the walls are quarried limestone the opening is a stone one. The Plan is explicit about what not to do with it: a replacement should be made to fit the original opening, changing the size of an opening to accommodate a standard door should be avoided, and the trim, sill, lintel and cap around the frame should be retained.

So the sequence is measure, approve, order. Give the rough opening width and height when you send the form, and say whether the garage is attached, detached or a rural outbuilding. The door range and the Build Your Door designer come after that measurement, and installation into an opening like this is fitting work rather than a swap.

The district is mostly commercial, and so are its doors

The Plan's inventory of the 152 district properties counts 102 commercial and 27 purely residential, with the rest split between apartments, churches, municipal buildings, green space and three large service buildings visible from the street. The rule bites hardest on the overhead door at the back of a Queen Street or Water Street business and on the service buildings behind them, rather than on a suburban attached double. Commercial doors and commercial openers are a different order of hardware from a residential pair of springs, and on a storefront the Plan has a second say, because alterations to downtown storefronts are permit work in their own right.

The limestone outside the core belongs to a different industry now. Building stone is no longer quarried here, and the St. Marys Cement plant still takes limestone out of the ground and ships cement across North America.

The floodwall, and the one rule that names openings

A floodwall 550 metres long, built in 1990 where Trout Creek meets the North Thames, protects the downtown up to its designed 100 year level. The business area sits in the floodplain even so, and two provincial ministers approved a Special Policy Area allowing development there to a lower standard of flood protection than the regulatory flood would demand. One of its criteria reaches a garage directly: living spaces and building or window openings may not sit below the 1:100 year flood elevation. Cutting a new opening low in a downtown wall runs into that elevation before it reaches the heritage question. Hanging a door in an opening that already exists is not new development and is a separate matter.

Beyond the policy area the Town splits the valley into floodway and flood fringe, and a new detached garage on land near the river needs the Upper Thames River Conservation Authority as well as the Town, under Ontario Regulation 41/24. The Authority maps the regulated areas and asks that exceptions be checked with its planning staff.

Eighty-one days a year of freeze and thaw

No weather station in St. Marys carries published normals. The nearest that does is the wastewater plant at Stratford, 17 km northeast, on the 1981 to 2010 period: 218.5 cm of snow a year and 4.8 days of freezing rain or freezing drizzle. Set its 149.6 nights a year at or below zero against its 296.8 days that climb above it and about 81 days land on both sides of freezing, below overnight and above by afternoon. That is arithmetic from two normals rather than a normal itself, and it is what tires a door: a bottom seal perished and refrozen to the slab, springs asked to lift the weight of ice.

Winter turns that into a short list of calls. A door shoved off its rollers on a hard morning is an off-track job, a spring that let go while the door was frozen to the slab is spring repair, a unit that hums without shifting the extra weight is opener repair, and a door that starts down then reverses is usually the safety sensors, whose lenses fog in the cold. The rest is ordinary repair. Say the street, whether the property is designated or in the district if you already know, and what the door is doing, on the contact form or at info@protechgarage.ca.
