Most homeowners think about window wells in the fall or after a spring flood scare. Summer tends to get overlooked. But Colorado summers bring their own set of threats: intense UV exposure, sudden hailstorms, afternoon thunderstorms that drop significant rainfall in minutes, and wildlife looking for shelter. A quick inspection and a few targeted maintenance steps in early summer can keep your basement dry and your window wells functioning properly through the hottest months of the year.

What Colorado Summer Actually Does to Your Window Wells?

The Front Range does not have a gentle summer. Temperatures swing dramatically, UV radiation at elevation degrades plastic and rubber materials faster than in lower-altitude climates, and the afternoon thunderstorm season brings short, intense rainfall events that can overwhelm drainage systems that seemed fine all spring. Add in the insects, small animals, and plant growth that peak during summer months, and your window wells face a different set of challenges than they do the rest of the year.

The good news is that summer preparation is straightforward. You are mostly inspecting, clearing, and correcting small issues before they compound.

Step One: Clear Debris and Check the Drainage Bed

Winter and spring leave a residue. Twigs, leaves, dirt, and decomposing organic matter accumulate at the bottom of window wells over the colder months, and that material does not just look bad. It blocks drainage, invites pests, and holds moisture against the well structure.

Start by removing everything from the bottom of the well by hand or with a shop vacuum. Once the base is clear, look at the condition of the drainage gravel. You should have between 6 and 12 inches of clean pea gravel or washed stone at the bottom. If you are looking at compacted dirt, mud, or debris-contaminated gravel that is no longer draining properly, scoop out the compromised material and replace it. This gravel layer is what allows water to move away from your foundation during a rainstorm, and it cannot do that job when it is clogged.

While you are at the bottom of the well, inspect the shell itself. Look for rust, cracks, or any visible shifting away from the foundation wall. Small issues caught now are far less expensive to address than the same issues after a summer of heavy rain events.

Step Two: Inspect and Upgrade Your Cover

Window well covers take a beating during Colorado summers. UV exposure causes polycarbonate and bubble-style covers to yellow, become brittle, and eventually crack. Hail can damage structurally sound covers just a season ago. A cover that looks intact from a distance may have stress fractures or a compromised fit that lets water and debris in during a storm.

Pull the cover off and examine it closely. Look for cracks, UV discoloration, and any warping that would prevent it from seating tightly against the well rim. A cover that does not fit snugly is not doing its job. Summer thunderstorms on the Front Range can drop a significant amount of rain in a very short window, and a loose or cracked cover allows that rain to funnel directly into the well.

If your cover is damaged or missing, summer is the right time to replace it. A properly fitted cover keeps out rain, debris, and the birds, mice, and insects that see an uncovered window well as ideal summer real estate.

Step Three: Check Your Window Seals and Egress Operation

Summer is the season when basement windows actually get used. Homeowners open them to ventilate the space, which means any failure in the window seal becomes immediately apparent as warm, humid air pours in around the frame.

Walk around the exterior and check the caulking and weatherstripping on each basement window. Look for gaps, cracking, or areas where the sealant has pulled away from the frame. These gaps allow moisture and conditioned air to move freely in both directions and provide entry points for insects.

If you have an egress window, test it. Open it fully and make sure it operates smoothly without binding. Check that any built-in ladder or steps in the well are clear of debris and accessible. An egress window that cannot be opened quickly in an emergency defeats its entire purpose, and summer inspections are a good time to confirm everything works before you need it.

Step Four: Address Landscaping Around the Wells

Summer plant growth is aggressive along the Front Range. Shrubs, perennials, and ground cover that were well-behaved in May can be crowding your window wells by July. Overgrown vegetation around window wells reduces airflow, traps moisture against the structure, and can redirect surface water runoff directly into the well during a rainstorm.

Trim back any bushes, ornamental grasses, or plants that are growing over or against the well. You want clear airflow around the perimeter and no plant material hanging into the well space itself.

While you are outside, check your downspouts. The standard recommendation is that downspouts discharge at least 3 to 5 feet away from the foundation. If yours are dropping water closer than that, an extension is an inexpensive fix that meaningfully reduces how much water your window well drainage system has to manage during a heavy rain event.

Frequently Asked Questions

How often should I clean out my window wells?

Twice a year is the minimum: once in spring after snowmelt and once in fall before winter sets in. A quick midsummer check is worthwhile if you are in an area with heavy tree coverage or if you have had significant storm activity. The goal is to make sure the drainage gravel is clear before the peak thunderstorm season hits.

What kind of gravel should be at the bottom of my window well?

Pea gravel or three-quarter-inch washed stone works best. Avoid fine sand, bark mulch, or decorative stone with fine particles, all of which compact easily and migrate into the drain. You want clean, coarse material that water can move through freely.

How do I know if my window well cover needs to be replaced?

Look for visible cracks, significant UV yellowing or clouding, warping that prevents a tight fit, or any damage from hail impact. A cover that no longer seats snugly against the well rim is not providing meaningful protection, regardless of how it looks from a distance.

Can I do window well maintenance myself?

Most routine maintenance, clearing debris, checking gravel, inspecting covers, trimming vegetation, and testing window operation, is well within reach for a homeowner with basic tools. Where professional help makes sense is when you find structural issues: rust, shifting, cracks in the well shell, or drainage that is not clearing properly, even after the gravel has been cleaned.

Do window wells need to be inspected even if I have not had any basement water problems?

Yes. Many window well issues develop on the exterior side of the structure, hidden against the soil, before any symptoms appear inside the basement. Catching rust, gaps, or drainage problems during a routine inspection is significantly less expensive than addressing them after a flooding event.
