Can You Build Hardscaping and Retaining Walls During a Colorado Springs Winter?

If you have a steep lot, a failing slope, or a backyard you have been dreaming about for years, you may have assumed that every outdoor project stops when the first snow falls. It is one of the most common beliefs we hear from Colorado Springs homeowners, and it is only partly true.

Winter does change how we build. It does not shut the whole job site down. For the right projects, the cold months are some of the best times to do heavy site work on a Front Range property. Here is what actually works, what does not, and how to use the off-season to your advantage.

Yes, depending on the type of wall. Boulder retaining walls can be built through most of the winter because the stones are set by weight and placement, not by anything that has to dry or cure. Poured concrete elements can also be built in the cold when the crew protects them properly. What stops work is not a cold number on the thermometer. It is frozen ground that cannot be compacted, concrete that could freeze before it hardens, and snow or ice that makes heavy equipment unsafe.

Colorado Springs helps us here. Our winters are cold, but they are also dry and sunny, and many winter afternoons climb above freezing even after a hard freeze overnight. That pattern gives crews steady working windows that homeowners in snowier, wetter climates do not get.

Firm, dry ground is easier on your property than wet spring ground. Building a boulder retaining wall means bringing in excavators and loaders that weigh many tons, and when the soil is soft and saturated, those machines leave deep ruts, tear up the lawn, and churn mud. Colorado Springs clay is especially unforgiving when wet. It turns sticky and slick, and it compacts badly under heavy loads.

In late fall and winter, the ground is typically cold, firm, and dry. Machines sit on top of it instead of sinking into it. That means:

• Less damage to your existing lawn and landscaping. Firm ground carries the equipment without rutting, so there is less to repair afterward.
• Less erosion risk during construction. Spring thaw and spring storms put the most water on exposed, freshly disturbed slopes. Doing the earthwork before that season means the structure is in place before the water arrives.
• Better access. Dry, firm ground makes it easier to get large boulders and equipment onto steep or tight foothill lots.

Something to note: the ground in Colorado Springs does not stay frozen for months at a time. It freezes and thaws repeatedly, which is why crews watch conditions day by day and adjust the schedule instead of working to a fixed calendar.

Not every part of a project handles cold weather equally. This table shows how we think about it.

Dry-set boulder terracing is the most winter-friendly retaining wall there is, because the stones hold the hillside by their own weight. Each boulder is placed with heavy equipment, with roughly a third to a half of it buried into the slope. Nothing is glued, mortared, or poured, so there is nothing that has to dry or cure before the wall does its job.

Behind the boulders, crews place layers of drainage rock and, where needed, drain pipe to carry water away from the wall. This matters a great deal in our climate. Water that builds up behind a wall and then freezes is what pushes walls out of place, so good drainage is part of the wall, not an add-on. That drainage gravel is placed on thawed, unfrozen material, with any frost cleared away first.

Because the finished wall is flexible rather than rigid, it also moves with our freeze-and-thaw cycles instead of cracking against them. That is a big reason we like boulders for Front Range hillsides, in any season.

Concrete can be poured in winter, but only if it is protected while it hardens. Fresh concrete needs to stay warm for roughly the first couple of days. If it freezes before it gains strength, it can be permanently weakened. For a fireplace, outdoor kitchen, or covered structure, the footing under it is what keeps the whole thing stable for decades, so this is not a place to cut corners.

Cold-weather concrete work generally includes:
 

• Never pouring onto frozen ground. The soil is thawed first, or the frost is removed, so the footing sits on solid, stable material.
• Insulating blankets over the fresh concrete. These trap the heat the concrete naturally produces as it hardens.
• Watching the forecast closely. Pours are scheduled for the milder days and protected through the cold nights that follow.
• Setting footings below the frost line. In Colorado Springs, footings generally go about 36 inches deep so freezing soil does not lift them.

This is the one place where winter does limit us, and we would rather tell you that up front. The gravel base under a flagstone or paver patio has to be compacted to be solid, and it cannot be properly compacted if it is frozen or sitting on frozen soil. A base that is rushed in freezing conditions can settle unevenly later, and you will see it in the surface.

That does not mean patios are off the table. On the milder stretches we get through winter, with temperatures above freezing and unfrozen soil, base work can proceed. If conditions are not right, we would rather hold that step than risk it. In many cases, the smartest plan is to do the earthwork, walls, drainage, and footings now, and set the stone surface in spring.

The real advantage of winter is not only what can be built. It is what gets done before everyone else starts. Every spring, the same thing happens in Colorado Springs: as the weather warms, a wave of homeowners decides they want projects done by summer, and the best installation dates fill up quickly.

If you commit to a master plan in the fall, you move ahead of that line. Here is how the timeline typically works:

1. November: design and site assessment. We walk your property, evaluate the slope, soil, and drainage, and develop a master plan around how you want to live outdoors.
2. Winter: engineering and permits. Taller retaining walls and covered structures generally need engineered plans and permit review, and that takes time. Doing it in the off-season means approvals are in hand before the building season starts.
3. Winter, on workable days: early site work. Depending on your project, excavation, boulder work, drainage, and footings can begin when conditions allow.
4. Early spring: your project is first in line. Instead of starting the planning process in April, your design is finished, your permits are in place, and your crew is ready to go when the ground warms.

The result is a finished outdoor space earlier in the summer, which is when you actually want to use it.

A few things stay the same in any season. Any wall over about four feet, and most covered structures, need proper engineering and permits in El Paso County. Drainage has to be designed correctly, because water is the enemy of every retaining structure on the Front Range. And weather days are real. A heavy snowstorm or a deep cold snap will pause work, and a good contractor will tell you that honestly instead of promising a date the weather cannot keep.

If you have been waiting for spring to begin thinking about a hillside, a retaining wall, or an outdoor living space, November is a good time to start the conversation. You do not need to wait for the snow to melt to move forward.
