Drive up Main Street in Lemont, then drive fifteen minutes west into the newer subdivisions, and you have effectively visited two different towns.
Roofline lighting styles in Lemont have to account for that split, because a plan that flatters a century-old limestone-and-frame house on the bluff will look undersized on a 4,000-square-foot brick two-storey — and the reverse looks worse.
The old village climbs the bluff above the Des Plaines valley and the canal corridor: smaller homes, steeper and simpler roof pitches, front porches, narrow lots, limestone foundations and trim. West of there, the 1990s and 2000s subdivisions brought large brick and stone houses with multi-gable elevations, attached three-car garages and generous setbacks.
Here is what actually suits each, and why.
Bulb Size Is the First Decision, Not the Last
Most homeowners pick a colour and never think about bulb size. It is backwards — size is the decision that determines whether a display looks proportionate.
C9 is the large, traditional strawberry-shaped bulb. High visual mass, reads from a distance, classic. Right for big elevations and houses set well back.
C7 is the same shape one size down. Cleaner, more restrained, better on smaller or more detailed homes where C9 looks heavy and crowds the trim.
Mini lights are for wrapping — porch columns, spindles, trees, shrubs. They do not belong on a roofline.
Get this wrong and no amount of good installation rescues it. An oversized bulb on a delicate older porch makes fine trim look clumsy; an undersized bulb on a wide suburban elevation simply disappears.
The Bluff Homes: Restraint and Following the Detail
On Lemont's older stock, the architecture is already doing work. The lighting's job is to trace it, not to add a second design on top.
C7, generally. Proportionate to smaller elevations and shorter setbacks, and it does not overwhelm original trim.
Follow the porch. On homes with a real front porch, outlining the porch roof edge and wrapping the columns is usually more effective than concentrating everything on the main roofline. It frames the front door, which is where the eye goes anyway, and it reads beautifully at the close viewing distances these narrow lots produce.
Follow every jog. Older rooflines step, return and change pitch. Cutting the corner across a bay or skipping a short return is instantly visible when someone is standing fifteen feet away on the sidewalk.
Warm white, always. Around 2700K. Lemont's limestone and painted wood both go cold and slightly grey under cooler white. Warm white keeps stone looking like stone.
Nothing driven into the house. On older painted woodwork this is not a preference, it is the whole reason to hire someone. A staple through original trim breaks the paint film and water gets into the hole. Everything should ride on clips that grip the shingle edge or gutter lip by tension alone.
The Subdivision Homes: Scale and Completeness
West of the village the problem inverts. These elevations are big, complicated and set back — and they punish incompleteness rather than excess.
C9, usually. Visual mass that survives a deep front lawn. C7 on a wide two-storey set back sixty feet tends to look thin.
Every plane, no exceptions. A typical elevation here has a main gable, a secondary gable over the garage, a bump-out or two, sometimes a dormer, and a covered entry — all at different heights. The standard shortcut is running the easy lower eave and skipping the high peaks. From the street the house then reads as half-lit, and the eye goes straight to the dark gable.
Spacing consistency over a long run. Wide elevations expose drift. Bulbs spaced by feel wander, and sections end up visibly tighter or looser.
Warm white on warm masonry. These homes lean on brick and stone in tans, reds and earth tones. Cool white reads blue against all of it.
If you want to see how this gets scoped for a specific elevation, our professional christmas light installation starts from photos rather than an appointment.
Where Both Kinds of House Agree
Three things are non-negotiable regardless of which Lemont you live in:
Hidden wiring. No orange cord over a porch rail, no visible run down a brick face. Wiring goes down downspouts and along trim lines.
No sag. Clips seated properly so the line stays taut between attachment points. One drooping bay undoes an otherwise perfect run.
Commercial-grade LED. Illinois winters cross 32°F dozens of times in a season. Water works into a retail-grade socket, freezes, expands, and the bulb fails — which is why a store-bought display that looked sharp on December 1st has dark sections by New Year's.
A Quick Comparison
| Bluff / historic homes | Newer subdivisions | |
|---|---|---|
| Bulb | C7 | C9 |
| Hero element | Porch and entry | Full roofline, every plane |
| Viewing distance | ~15 ft, on foot | 60+ ft, from a car |
| Biggest risk | Overdoing it | Skipping the high gable |
| Attachment | Critical — original trim | Standard clips |
| Colour | Warm white on stone | Warm white on brick |
Frequently Asked Questions
Should I use C9 or C7 on my Lemont home?
C7 generally suits the smaller, closer-set homes in the older village, where C9 can look heavy against fine trim. C9 suits the larger subdivision elevations set back behind a front lawn, where smaller bulbs lose definition.
Can holiday lights damage an older home?
They can if they are attached with nails, screws, staples or adhesive, all of which break the paint film on original woodwork. Clip-mounted systems that grip the shingle or gutter edge avoid the problem entirely.
Is warm white or multicolour better?
Warm white at roughly 2700K flatters limestone, painted wood and warm brick, which is why it suits both Lemont housing types. Multicolour is a legitimate family preference but tends to flatten architectural detail on a highly detailed elevation.
When should I book in the Chicago suburbs?
October. Installs across Lemont and neighbouring Homer Glen run mid-October through mid-November, and pre-Thanksgiving dates fill first.
The Takeaway
Lemont's split housing stock is not a complication — it is just two different briefs. On the bluff, pick one hero element and light it properly with C7. In the subdivisions, go C9 and finish every plane.
Both fail the same way: somebody skips the awkward part.
