Water Damage in Northglenn: What We Actually See Here

Northglenn began as one idea on a 280-acre field. In the spring of 1959 the Perl-Mack Company laid out what was then Colorado’s largest pre-planned community, near what is now I-25 and 104th Avenue. More than 15,000 people came through the first five model homes that June; by October 1962 the development had 3,000 homes and 10,000 residents, and in 1961 Life magazine and the National Association of Home Builders called it the most perfectly planned community in America. That history is the most useful thing to know about water damage here: a huge share of Northglenn’s houses went up inside one narrow window, so their plumbing, water heaters and sewer laterals are all reaching the end of their service lives at once.

That shows up as brittle galvanized and early copper branch lines, original clay-tile sewer laterals whose mortar joints have separated after five decades of freeze-thaw, and mature street trees whose roots found those joints long ago. Plumbing contractors working here describe the same pattern: 1959–1980 housing on expansive clay soil, with root intrusion near universal in lines never replaced. When a lateral backs up in a slab-on-grade ranch off Huron Street, the water comes up the lowest fixture and spreads under carpet and cabinet toe-kicks.

Northglenn also has a documented cloudburst problem. On September 15, 2013, the closing day of the Front Range flood, the National Weather Service reported that flash flooding was most significant in the northern Denver metro from Northglenn to around Broomfield. That was rain landing on Northglenn, not a river arriving from elsewhere, and homes near Croke Reservoir and the Big Dry Creek corridor already sit where groundwater runs higher.

End-of-life plumbing in a city built all at once

Most of our Northglenn calls are undramatic: a toilet supply line that lets go while the family is at work, a water heater rusting through in an interior closet, a pinhole in copper behind a mid-century tiled bathroom wall. In houses this age water travels farther through wall cavities than in new construction, so we meter behind and beneath the visible damage before deciding what has to come out.

Slab and low-basement homes on shifting clay

The expansive clay under this part of Adams County swells when wet and shrinks when dry, working on the soil under your foundation and around your sewer line at the same time. On the ranch plans that dominate the original Perl-Mack neighborhoods, a slow slab leak can run for months with no sign but a warm patch of floor or a water bill that crept up.

How Fast We Can Reach Northglenn

We work out of 3787 Ronald Reagan Blvd, Unit 1 in Johnstown, about 30 miles north of you and a direct run down I-25 to the 104th or 120th Avenue exits. Outside of rush hour or bad weather that is typically under an hour, and someone answers our phone 24 hours a day.

Frequently Asked Questions About Water Damage in Northglenn

My Northglenn home is from the original 1960s build — what fails first?

Usually the small stuff: toilet and faucet supply lines, angle stops that no longer seat, water heaters past fifteen years. After that, the sewer lateral. Homes from the 1959 to 1970 era often still have clay-tile lines with mortar joints, where root intrusion and separated joints are common. A backup in one of those is a contaminated-water job, not a mop job.

Why does water spread so far in these mid-century houses?

Because the cavities are continuous and the finishes are absorbent. Plaster and old hardwood wick moisture, mid-century walls rarely have modern blocking, and many Northglenn ranches run ducts through the floor system, carrying damp air into rooms nowhere near the leak. We map it with moisture meters and thermal imaging instead of cutting a guess.

Does the 2013 flooding still matter for my house?

It matters as a warning about mechanism. The National Weather Service singled out Northglenn as a focus of flash flooding on September 15, 2013 — intense local rain, not river flooding. Ground that took water then can do it again, especially near Croke Reservoir and Big Dry Creek, so we look at grading, window wells and where your sump discharges.

Can you dry a Northglenn basement without gutting the whole thing?

Often, yes. Early enough, we dry many finished basements in place with directed airflow, controlled dehumidification and cavity drying, removing only the wet lower band of drywall and saturated insulation. What forces bigger demolition is time and contamination, which is why calling at hour two beats calling on day three.

Should I call my insurance company first?

Call Revive first. Documenting the source, moisture readings and affected materials before anything is disturbed gives your carrier the evidence a claim needs. We are family operated and locally owned by Levi, born and raised in Northern Colorado, and we work with all insurance carriers. The inspection is free.

If you have water where it should not be, shut the supply off if you can safely reach it and call us at (720) 340-3499 — day, night, weekend or holiday, and we have been at this since 2016. Our full service area list includes neighboring Broomfield and Brighton, and you can read how we handle a loss start to finish on our water damage restoration page.
