Gutters do quiet, unglamorous work in Boulder, and when they fail you find out the expensive way. Sitting right against the foothills, Boulder catches heavy summer downpours and hail that can dent and clog a gutter in a single afternoon, then hands those same channels a winter of freeze-thaw that loads ice into every seam and sag. Undersized or poorly pitched gutters overflow against fascia and siding, and on the older homes near the mountains that water finds aging wood trim fast. The point of a gutter is simple but unforgiving: move every gallon off the roof and away from the foundation before it can do damage.

That job looks different across Boulder's housing stock. The century-old Victorians of Mapleton Hill and the brick bungalows of Whittier and Newlands often have original wood fascia and tight historic detailing that demands careful flashing, while the 1960s ranches that fill Table Mesa and the newer builds out in Gunbarrel and North Boulder (NoBo) each drain differently. CR Custom Exteriors is a family-owned, licensed and insured contractor based just down the road in Erie with 10+ years on the Front Range. We fabricate seamless aluminum gutters on site, set the correct pitch and downspout placement for your roof, and integrate the gutters with your roofing and siding so the whole exterior sheds water as one system.

Sized for Boulder's storms and ice

Common questions

What gutter material holds up best for Boulder's weather?
We install seamless aluminum gutters, which we fabricate on site so there are no mid-run joints to leak or pull apart under freeze-thaw ice loading. Aluminum resists corrosion, takes Front Range hail well, and pairs with oversized downspouts and hail-ready gutter guards so heavy Boulder downpours drain fast instead of overflowing onto your fascia and siding.
Why do gutters matter so much on older Boulder homes?
On the century-old Victorians in Mapleton Hill and the brick bungalows of Whittier and Newlands, the fascia and trim are often aging wood that rots quickly once water spills over a clogged or sagging gutter. Correct pitch, properly placed downspouts, and guards keep that water moving away from the foundation and off the woodwork, which protects exactly the materials that are hardest and most expensive to replace on an older home.
What affects the cost of new gutters in Boulder?
Cost depends on the linear footage of gutter, how many stories and how steep your roofline is, the number and size of downspouts needed for proper drainage, and whether you add gutter guards or need fascia repair behind old runs. A Gunbarrel ranch and a multi-story home near the foothills price out very differently, so we give every Boulder homeowner a free, detailed estimate with no surprises.
