ABOUT OUR COMPANY
Your neighbors in
Longmont, building
yards that last
GM Outdoor Hardscape LLC is a family business. Giovanni and Marisol started out taking small landscaping jobs on evenings and weekends around Longmont. Neighbors kept recommending them to other neighbors, and eventually the side work outgrew the day jobs.
That's still how we operate. Every patio, wall, and yard we build is a job someone in this community will walk past and judge us on so we do it the way we'd want it done at our own house.
What we build
Everything outside
your back door,
handled by one crew
Hardscape, softscape, concrete, and water, we build the whole yard, so you're not chasing four different contractors around Boulder County.
Hardscaping
Paver patios, walkways, seat walls, and fire pits built on a base that survives Colorado
freeze-thaw.
Retaining Walls
Engineered block and boulder walls that hold back slopes, carve out usable yard, and stop erosion for good.
services
Concrete
Driveways, slabs, sidewalks, and steps poured and finished to hold up to Longmont winters.
Landscape Installation
Sod, grading, planting beds, mulch, rock, and edging a complete yard, installed start to finish.
Services
Irrigation
Sprinkler installation, repairs, and seasonal blowouts that keep your investment green without wasting water.

Seasonal Services
Spring and fall cleanups, aeration, and winter care that keep the yard sharp all twelve months.

The four marks in our logo
Built for all four Colorado seasons
The snowflake, blossom, sun, and leaf in our logo aren't decoration. They're the four seasons your yard has to survive and the four times a year we're thinking about your property.
Winter
Irrigation blown out, hardscape holding through freeze-thaw, walks and drives kept clear.
Spring
Cleanups, aeration, bed refresh, sod and planting, irrigation started and dialed in.
Summer
Patio season. Efficient watering, healthy turf, and the outdoor room you actually use.
Fall
Leaf removal, cutbacks, overseeding, and winterization before the first hard freeze.

We show up when we say
Punctuality is the number one thing our clients tell us set us apart. You get a start date, and we hit it.

Built for Colorado
Proper base prep, compaction, and drainage. Anyone can lay pavers that look good in June — ours still look good after four Front Range winters.

I reached out just looking for an estimate and was genuinely impressed by how quickly they responded. Professional, courteous, and incredibly prompt with communication. In a world where it's hard to even get companies to call you back, their responsiveness really stood out. Definitely made a great first impression.

They were great to work with and did a great job clearing an area where junipers had been removed and landscaping it with rocks.

GM outdoor hard scape responded exceptionally quickly and scheduled me same day for a sprinkler winterization. We will hire him every year! Highly recommend.
