Hydro jetting
Clears roots and grease
You have tried the plunger. You have poured chemicals down the drain. Maybe you even rented a drain snake from the hardware store. Nothing worked, and now the problem is worse. You are in the right place. Castle Rock Plumbing specializes in drainage problems that other methods cannot fix. When you need a drain cleared today - not next week - call us at (970) 703-0305.
Drain problems look different in every home. Your kitchen sink might fill up with dirty water when the dishwasher runs. Your shower might drain so slow you end up standing in a puddle. You might hear a weird gurgling sound from the toilet when you run the bathroom sink. All of these are signs something is wrong.
Castle Rock has some things that make drain problems more common here. The soil has a lot of clay in it. Clay swells when it gets wet and shrinks when it dries out. That puts a lot of pressure on pipes underground. Tree roots are another big one - they find their way into pipes and grow until the pipe cracks or gets blocked. Older homes in Castle Rock still have the original clay or cast iron pipes, and those break down over time. Spring snowmelt and summer storms can also push a lot of water through drain systems all at once.
A lot of people try to fix drains themselves first. The problem is that store bought drain cleaners only poke a small hole through a clog. They do not get rid of it. That is why the drain clogs again a few weeks later. A real fix means finding out what caused it and taking care of that.
We handle all kinds of drain jobs. For regular clogs in kitchen sinks, bathroom drains, and floor drains, our Drain Cleaning service gets things moving again fast. For tougher clogs that basic methods cannot clear, our Clogged Drain Repair crew brings the heavy equipment.
Before we recommend any big repairs, we use a Sewer Camera Inspection to look inside your pipes. We can see exactly what is going on before we do anything. No guessing. No paying for work you do not need. We show you the video so you can see it yourself.
For roots and built up grease, Hydro Jetting is the best option. It uses high pressure water to blast everything out and clean the pipe walls. When a sewer line is cracked or broken, our Sewer Line Repair service fixes it. If the pipe is too far gone, we do full Sewer Line Replacement and can often do it without tearing up your whole yard using Trenchless Sewer Repair. We also do Backflow Testing to make sure your system is safe and up to code.

Drainage solutions in Castle Rock cost: French drains $2,000-$4,000, foundation drainage systems $3,000-$6,000, and downspout extensions $500-$1,200. Castle Rock's expansive clay soils require proper drainage to prevent foundation damage. Price depends on length, depth, and site conditions. Free estimates include soil analysis and drainage plan.
Castle Rock's expansive clay soils swell when wet and shrink when dry, causing foundation movement. Combined with spring snowmelt and summer monsoons, poor drainage leads to: foundation cracks, basement flooding, landscaping erosion, and structural damage. Proper drainage protects your home's foundation and can save tens of thousands in repairs.
Warning signs include: water pooling near foundation after rain, basement moisture or flooding, foundation cracks, doors/windows sticking, gutters overflowing, erosion in yard, or muddy areas that never dry. Castle Rock's 14-inch annual precipitation concentrated in spring/summer makes proper drainage essential. Early intervention prevents costly foundation repairs.
Best drainage depends on your property: French drains work for subsurface water, surface drains handle runoff, and foundation drains protect basements. Many Castle Rock homes benefit from combined systems. Proper grading directs water away from foundations. We assess soil type, slope, and water sources to design effective drainage solutions.
Yes, drainage systems need annual maintenance to function properly. Clean gutters seasonally, check downspout connections, remove debris from surface drains, and inspect for settling or damage. French drains may need flushing every 3-5 years. Castle Rock's cottonwood seeds and pine needles commonly clog drains. Regular maintenance prevents system failure.
