Quick answer: Roughly half the detached garages in Kentwood, Big Spring don't have gutters — and every single one of them is quietly damaging a slab. Adding seamless gutters to a typical 2-car detached garage runs $650–$1,500 installed, or 15–25% less if bundled with a main-house install. It's the single cheapest slab-protection investment you can make.
Kentwood detached garages: the pattern we see
Kentwood is a 1960s Big Spring neighborhood right next door to Highland South. Most homes have a matching detached one- or two-car garage set back on the property. And in about half the visits we do here, the main house has gutters but the detached garage is bare — either because the original builder skipped them or because they were removed at some point and never replaced.
The reasoning is usually "it's just a garage." The problem is Howard County's expansive clay soil doesn't care whether it's under a garage or a house — it swells and shrinks the same way, and unmanaged roof runoff around a slab is a slab-cracking event every time it rains hard.
What happens when a Kentwood detached garage has no gutters
- Roof runoff hits the concrete apron at the garage entrance during every rain. Splash-back stains the door and side walls.
- Water pools against the slab for 12–48 hours before soaking in. That saturates the clay directly under the slab edge.
- Clay expands underneath the slab edge. Slab tilts, either at the entry corner or along a wall.
- Cracks appear — usually a diagonal crack from the corner, or a stress crack along the door threshold.
- Garage door binds as the header shifts. This is usually the point at which the homeowner calls us.
By that point, you're not just adding gutters — you're looking at a potential slab repair too. Slab repair on a detached garage in Big Spring routinely runs $3,000–$10,000. Gutters to prevent it: $650–$1,500. The math is not close.
What a Kentwood detached garage install looks like
- 60–80 linear feet of 5" seamless aluminum gutter
- 2 downspouts (one on each end)
- 4–6 foot foundation extensions on each downspout, routing water AWAY from the slab
- Hidden hangers at 24–30" spacing
- Color-matched to your main house (we keep the palette on file for Kentwood homes we've done before)
Install takes half a day for our crew of two. Bundled with a main-house install, we usually knock out both in one visit.
The one exception
If your Kentwood detached garage roof drains onto grass more than 4 feet from the slab, and you've been in the home 10+ years without any slab movement, you may not need gutters. That's a rare setup but it exists. We'll tell you honestly during the free measurement if you're one of the exceptions.
Bundle pricing worth asking about
Since we're already driving from Midland along I-20, we can offer meaningful bundled discounts when we do multiple structures on the same property or multiple Kentwood/Highland South homes in the same week. Ask about it during your quote.

Frequently Asked Questions
Do I really need gutters on my Kentwood detached garage?
If the detached garage sits on a slab (most Kentwood garages do) and the roof edge drips onto the driveway, sidewalk, or ground adjacent to the slab — yes. Howard County has expansive clay soil that swells and shrinks with moisture, and a slab without gutters gets hit with the full roof runoff during every rain. That's the fastest path to slab cracks and door misalignment.
How much does it cost to add gutters to a detached garage in Kentwood?
A typical Kentwood 2-car detached garage needs 60–80 linear feet of gutter, which runs $480–$1,200 installed at our standard $8–$15 per linear foot rate. Add $75–$150 per downspout (usually 2 per garage), and $25–$50 per foundation extension. Total: $650–$1,500 all-in for a garage-only install.
Can you bundle the garage gutter install with the main house?
Yes, and that's the most cost-effective way to do it. When we're already on-site with the roll-forming machine set up, adding the detached garage typically costs 15–25% less per linear foot than a standalone garage-only visit — since the setup and travel are already paid for.
What size gutter should I install on a detached garage in Kentwood?
5-inch is almost always sufficient for a detached garage roof. The catchment area is small enough that even in a heavy Big Spring thunderstorm, 5" handles the flow. Save the 6" upgrade for the main house where roof valleys converge on limited gutter sections.
