Single-skin steel
One layer of steel, no insulation. Light, cheap, and genuinely right on an unheated detached garage holding a car and a mower. Dents more easily, and drums when the wind gets behind it.
01 Repair & installation
Garage door installation in Evanston, IL
A door is not a product you pick off a shelf and screw to a wall. It is sized to an opening, hung off framing that may be a hundred years old, and balanced against springs chosen for its weight — so we measure first and quote second.
- Headroom, backroom, side room and header condition measured before any number
- Low-headroom and narrow-opening work on pre-war detached garages
- Insulated, single-skin steel, wood and carriage-house overlay
- We flag village width rules and historic review before you order
02 Before anyone quotes
The eight measurements that decide what door you can actually have
Anyone quoting garage door installation in Evanston over the phone, without asking these questions, is quoting a standard door and hoping your garage is standard. On a building put up in 1924 it very often is not.
This is the survey. It takes about twenty minutes.
- Opening width and height at three points each — pre-war openings are rarely square, and the narrowest point governs
- Headroom: the gap between the top of the opening and the ceiling, joists, or whatever else is up there
- Backroom: depth into the garage, which needs the door height plus roughly 18 inches of horizontal track
- Side room: about 3¾ inches of clear jamb each side for standard vertical track
- Header condition — the timber the spring anchor bolts into, which on an old garage may be one sagging beam
- Jamb rot and floor level across the full opening — a settled slab changes the bottom seal spec
- Whether a grounded outlet is in reach of an opener head, or an electrician needs to come first
- How we reach the door on install day — alley width, overhead wires, and where the old one goes
If the header is soft or the jambs have gone, that is carpentry before it is door work, and we tell you at the survey rather than on install day. A door hung off rotten timber becomes a door off its track within two winters.
03 The pre-war problem
Your opening is eight feet wide and your car is not
Roughly four in ten Evanston homes were built before 1940. The garages behind them were built for a Model A, and the standard single opening of that era is eight feet wide — nine if you were doing well. A modern mid-size SUV is about six and a half feet across the mirrors. That leaves a hand's width each side, and it is why so many alley garages in south Evanston and around the Oakton bungalow blocks have paint scraped off both jambs.
People assume the fix is a wider door. Usually it is not, or not first. Widening means cutting out the header, sizing a new one, rebuilding both jambs and often re-siding the wall face — and on a garage sitting three feet off the rear lot line you cannot push the wall out to compensate. What we can often do instead:
- Fit a door with slimmer jamb hardware and reclaim an inch or two of usable width
- Replace bulky old steel rollers and brackets with a lower-profile set
- Move the opener rail and photo-eyes out of the swept path so the tight bit is only the opening itself
- Where the header genuinely allows it, take the opening from eight feet to nine — a real gain, and a much smaller job than going to sixteen
Sometimes structural widening really is the answer, and we will say so — but we would rather you spent that money knowing it is the only route. More detail in our piece on narrow 1920s openings.
Headroom is the other pre-war constraint
A standard torsion setup wants around twelve inches above the opening. Plenty of old detached garages have six, sometimes four, because the rafters sit on top of the header. Not a dead end. A low-headroom track kit changes how the door turns the corner so a torsion system fits in a fraction of the space, and on some garages a rear-mount shaft solves it outright. Routine work here, not exotic.
04 Clearances
What the space around your opening has to give you
Rough working figures for a standard residential sectional. Real numbers move with the hardware, the drum size and the opener, which is why the survey exists — but if your garage is a long way short of the left-hand column, you already know the conversation involves a track kit.
| Clearance | Standard lift | Low-headroom option | What it is for |
|---|---|---|---|
| Headroom above the opening | About 12 in | As little as 4½ in with the right kit | Room for the torsion shaft, drums and the door's first horizontal section |
| Side room each side | About 3¾ in | Similar | Vertical track, brackets and the end bearing plate |
| Backroom into the garage | Door height plus about 18 in | Same or slightly more | The horizontal track and the opener rail behind it |
| Ceiling structure | Something to hang the rail from | Often nothing usable | Rail hangers on an opener — the reason wall-mount units exist |
| Header depth | Sound timber, full width | Sound timber, full width | The spring anchor bracket and the whole door's lifting load |
| Floor across the opening | Level within about ½ in | Level within about ½ in | The bottom seal has to touch concrete everywhere or wind and water get in |
Trade-typical working figures. Manufacturer instructions govern the actual installation, and general residential guidance is published by DASMA.
05 North Shore rules
In some villages the code decides how wide your door can be
This surprises people who have moved up from the city, and it is worth knowing before you fall for a wide single door.
Winnetka. The village code limits individual front-facing garage doors to nine feet wide, caps front-facing attached garages at twenty-two feet of total width on interior lots, and restricts front garage doors to a third of the lot width or eighteen feet, whichever is less. In practice that means a front-facing two-car garage in Winnetka is nearly always two separate doors, not one sixteen-foot double.
Kenilworth. The code caps the sum of door openings facing an abutting street at twenty feet, and a garage may not sit closer to the front lot line than the principal building setback. Kenilworth was platted deliberately without alleys, so essentially every garage there is street-facing.
Neither village is unreasonable about it, but both will hold you to it, and a door ordered to the wrong width is a door you own. Codes change, so confirm the current requirement with the village before you order — Winnetka's code is published online and so is Kenilworth's. We can tell you what we have seen approved; only the village can tell you what will be.
- Winnetka: front-facing doors capped at 9 ft each
- Kenilworth: 20 ft total street-facing opening
- Both: confirm current rules with the village first
- Evanston has no equivalent width cap — the constraint here is the existing opening
06 What to actually buy
Door types, and where each one earns its money around here
No brand names, because the brand matters far less than the construction, the gauge of the steel, and whether the thing was sized to your opening.
Insulated sandwich steel
Steel, foam core, steel back. Stiffer, quieter, far less prone to denting, and the only sensible choice on an attached garage or one with a room above. Also the door that makes a belt-drive or wall-mount opener worth the money.
When insulation is not worth it
On a detached garage with gaps under the eaves and a single-glazed window, an insulated door raises the R-value of one wall of a building you do not heat. Spend it on weather sealing instead — the Department of Energy guidance on where insulation pays is worth ten minutes.
Wood and wood-composite
Beautiful, heavy, and it moves. July here pushes dew points past 70°F for a dozen days, so wood swells and sticks; midwinter dries it back. Worth it on a coach house or a landmark property where appearance is the point.
Carriage-house overlay
A steel or composite sectional with an applied overlay that reads as a hinged carriage door from the alley. The look of a 1920s garage with the balance and safety of a modern sectional. Common in Northeast Evanston and Kenilworth.
Hardware, not just panels
Track gauge, hinge thickness, struts across the top section, nylon versus steel rollers, galvanised versus plain brackets. This is where a cheap installation is cheap, and where it fails first in a salt winter.
07 Install day
What actually happens when we fit the door
Most single-door installations are a morning. A double, or anything involving jamb repair or a track conversion, is a day.
The old door comes out
Springs de-tensioned safely first, then panels, track and hardware stripped back to bare jambs. We take the old door away and recycle the steel rather than leaving it stacked in your alley.
Jambs and header made good
Rot cut out, new jamb timber where needed, header checked and reinforced if the spring anchor is going into something tired. This part decides whether the door is still square in ten years.
Track, sections, springs
Vertical track plumbed to the opening, sections stacked and hinged, horizontal track levelled and hung, then springs wound to a count calculated from the finished door's weight.
Balance, seal, safety test
Hand balance checked with the opener off, bottom seal set against the actual floor line, opener force and travel limits reset, both photo-eyes tested against an obstruction while you watch.
Your existing opener usually carries over if it is sound and matched to the new door's weight. An insulated door is heavier, and we will say whether the opener is up to it rather than let it grind itself out.
08 Paperwork and timing
Permits, historic review, and how long the door takes to arrive
Two things catch people out on an Evanston installation, and both are easier to handle before you order than after.
Historic review can reach an alley garage
Evanston has five National Register districts and more than 850 individual local landmarks. On landmark properties and in the local landmark districts, a Certificate of Appropriateness is required for permitted exterior work visible from a public way — and the City's definition of a public way includes alleys. An alley-facing door in the Lakeshore, Ridge or Northeast Evanston districts is, by that definition, visible. Whether a straight swap triggers review depends on specifics, so call the City before you commit to a style. Start with the preservation pages and the permit information, and confirm the current requirement rather than trusting any page, this one included. We have written up how the review runs.
Doors are made to your opening
A garage door is not stock. Width, height, panel design, colour, glazing and hardware get specified and then built, which means lead time. Plain steel in common sizes moves quickly; overlays, odd widths, custom colours and wood take substantially longer, and longer again in spring when the whole North Shore decides at once. If your door is unusable meanwhile, we would rather do a holding repair than have you without a garage for weeks.
What we will talk you out of
Insulation on a garage you do not heat. A sixteen-foot opening cut into a header that does not want it. A heavy wood door on a settled slab with a marginal opener. And a new door where the real problem was the track or the cables all along — that one costs us a sale about once a month and it is still the right call.
Weighing a new door against fixing the one you have? The replacement page lays out the arithmetic. We survey across west Evanston, the Central Street blocks, Skokie and Wilmette from the shop on Brown Ave. Call (224) 505-2236 to book one, or see everything we do.
06 Questions we get asked
Installation questions from Evanston homeowners
What people ask at the survey, and what we tell them.
Can you widen my eight-foot garage opening to fit a bigger car?
<p>Sometimes, and it depends entirely on what is above the opening. Widening means removing the existing header, sizing and fitting a new one across the wider span, rebuilding both jambs and usually repairing the wall face. On a detached garage sitting three feet off the rear lot line you cannot push the wall out to compensate, so all the gain has to come from inside the existing footprint. Before we go there we will look at whether slimmer hardware and a lower-profile roller set buys you enough. Often it buys an inch or two each side, which is the difference between scraping and not.</p>
My garage has almost no headroom. Do I have to keep the old extension springs?
<p>No. Low-headroom track kits exist precisely for this, and old Evanston detached garages are where they get used. The kit changes how the door turns the corner from vertical to horizontal, letting a torsion setup work in as little as four and a half inches above the opening instead of the usual twelve. On some garages a rear-mounted torsion shaft solves it instead. Either way you get the better balance and the containment behaviour of a torsion system on a garage that was built assuming you would never have one.</p>
Is an insulated door worth it on a detached garage?
<p>Usually not, if the garage is unheated. Insulating one wall of a building with gaps under the eaves, a single-glazed window and an uninsulated slab does very little for the temperature inside, and the payback argument does not hold up. What an insulated door does give you is stiffness and quiet — the panels are far more resistant to denting and the door runs noticeably quieter, which matters if there is a bedroom above. On an attached garage, or a garage with an ADU over it, insulation is the obvious choice. On a plain detached garage, spend the difference on weather sealing and better hardware.</p>
How long does a new garage door take to arrive?
<p>Longer than most people expect, because the door is built to your opening rather than pulled off a shelf. Common widths in plain steel move reasonably quickly. Carriage-house overlays, custom colours, unusual widths and wood doors take considerably longer, and spring is the busiest ordering season on the North Shore. We give you a realistic window at the point of order and tell you if it slips. If your current door is unusable in the meantime we will do a temporary repair to keep the garage working rather than have you go without one.</p>
Do I need a permit to replace a garage door in Evanston?
<p>Requirements differ between a like-for-like door swap and work that alters the opening or the structure, and they change over time, so the honest answer is to confirm with the City rather than take a contractor's word for it. The bigger flag is historic review: on landmark properties and in Evanston's local landmark districts, permitted exterior work visible from a public way needs a Certificate of Appropriateness, and the City counts an alley as a public way. Ask before you order the door, because a style decision is much cheaper to change on paper.</p>
Can I keep my existing opener with a new door?
<p>Often, yes, and we will tell you honestly if the answer is no. Two things decide it. First, condition — a unit with a worn trolley or a tired drive gear is not going to improve because the door in front of it is new. Second, weight: if you are going from a single-skin steel door to an insulated one you have added real mass, and an opener that was already at its limit will strip its gear inside a year or two. If it does need replacing, <a href="/services/garage-door-opener-installation/">the opener page</a> covers what suits a low-headroom garage.</p>
What happens to my old door?
<p>We take it with us. The springs get de-tensioned before anything is dismantled, the panels and track come out, and the steel goes for recycling rather than into your alley or a skip you are paying for. On wood doors we ask first, because occasionally a homeowner wants to keep an original for a workshop wall or because the door is genuinely period. If your garage backs onto one of the unpaved alleys the City grades each spring, it also matters that we are not leaving a pile of panels where the grader has to go around it.</p>
Two narrow doors or one wide one for a two-car garage?
<p>If you are in Winnetka or Kenilworth, the code may make that decision for you — Winnetka caps front-facing doors at nine feet each and Kenilworth caps street-facing openings at twenty feet in total. Confirm current requirements with the village. Where you have a free choice, a single wide door is easier to drive through and cheaper to automate with one opener; two separate doors keep more structure between them, look right on older architecture, and mean one failure does not lock in both cars. On a pre-war garage with a centre post already there, two doors is usually the cheaper build.</p>
