Q&A
My fence near the Meramec River in Arnold keeps leaning after heavy rain. What could be wrong?
That's a common issue here. The soil near the river is often sandy or has a high clay content, which can shift or erode with heavy rain. This can cause fence posts to loosen or rot, leading to that leaning look. At Jnm Home Improvement, we assess both the soil condition and the post footing depth. A simple fix might involve re-setting the posts with gravel and concrete for better drainage. If the wood is rotted, we can replace the affected posts and sections with pressure-treated lumber or even recommend a more durable material like vinyl, which holds up better in our local climate.
I see a diagonal crack in my drywall that runs from a corner of a window. Is this just a cosmetic issue or a bigger problem?
A diagonal crack from a window corner actually sounds like a structural concern, not a simple drywall issue. In the Arnold area, homes built on clay soil often experience foundation movement as the ground expands and contracts. That stress usually shows up in drywall, especially around doors and windows. Our team at Jnm Home Improvement can diagnose the cause. We'll first check the foundation level and the soil around your home. If it's just minor settling, we can repair the drywall and reinforce the corner with tape and mesh. But if there's significant foundation movement, we'll recommend structural repairs first, like piering or grading, before we patch the drywall. This way, the fix lasts instead of coming back.
Our gate on our automatic gate system won't open, and we live on a sloped lot off Old Highway 61. Any idea why?
That's a frustrating one, especially on a slope. The most common cause on sloped drives is a misaligned gate track or an obstruction from mud or debris that washes down the slope. First, check the photo eyes to make sure they're clean and aligned. If the gate moves a few inches then stops, the motor's safety function is likely kicking in. For a more permanent solution, Jnm Home Improvement can inspect the gate's hinges and track to see if they've shifted due to ground movement—very common in Arnold with our freeze-thaw cycles. We can realign the track, adjust the gate arm, or install a stronger motor designed for slopes. If the soil has eroded under the gate post, we'll fix that foundation first to prevent future issues.
