Woodglen is the neighborhood around 120th Avenue and Colorado Boulevard in Thornton. The median home there was built in about 1974, mostly single-family houses in subdivisions, plus townhomes such as Woodglen Square. Owners of houses that age usually call about a drain that keeps slowing down, a sewer smell in the basement, blue-green stains or pinhole leaks on copper, and water heaters that have been replaced once or twice already.
The causes tend to be age. Sewer laterals of that era were commonly clay or cast iron, and roots get into clay joints or the line settles and holds water. Copper supply pipe can wear through in small pinholes, especially where water is hard and the pipe is old. Thornton water averages about 200 mg/L hardness, so scale builds on heating elements and tank bottoms as well.
For a slow or backed-up drain, stop running water and skip the chemical opener. We run a camera through the sewer line before recommending digging, and the answer is sometimes just drain cleaning and sometimes sewer line repair. If you see a wet spot, a stain spreading on a ceiling, or a hissing sound in a wall, shut the main water valve and see water leak repair.
Front Range cold snaps hit hose bibs, garage water heaters and any pipe along an unheated exterior wall. Disconnect hoses in the fall and know where the main shutoff is. Call when water will not stop, when sewage shows at a floor drain, or when hot water is gone. We explain what we find and put a written scope and price in front of you to approve before work begins. Call (720) 856-5811, Monday to Saturday, 9am to 6pm.

Plumber in Woodglen · Local Notes
- •Woodglen sits around 120th Avenue and Colorado Boulevard. Homes.com puts the median build year near 1974, with single-family subdivisions, split-levels and townhomes.
- •Homes of that era often combine copper supply with clay or cast iron drain and sewer pipe. Pinhole leaks and root entry at joints are the usual age-related failures.
- •Thornton water averages about 200 mg/L hardness (roughly 11.7 grains per gallon) and the city does not soften it, so scale collects in water heaters.
- •Front Range clay soils move with moisture, and the Colorado Geological Survey lists sewer lines among what expansive soil can disrupt. Cold snaps stress hose bibs and garage plumbing.
