What's included

Drain & sewer work, done thoroughly.

A clogged drain is rarely just a clogged drain. The location of the blockage, how long it's been getting worse, what fixtures back up at the same time — all of those tell you whether it's a local trap, a branch line, a vent issue, or something deeper in the main. Kiley diagnoses first, then clears.

We carry sectional drain machines for sink and tub lines, larger main-line machines for sewers and floor drains, and we coordinate sewer-camera inspections when something deeper is suspected. Most residential drain calls are diagnosed and cleared on the first visit.

We see a lot of older Metrowest neighborhoods with original cast iron drain stacks and clay sewer mains. Both have failure patterns we know — cast iron rots from the bottom of the pipe, clay separates at joints and lets roots in. Where appropriate, we'll show you what the camera saw and explain whether long-term repair is the smarter spend.

Common signs you need drain service

Our process

Diagnose first, clear properly.

Step 01

Locate the blockage

We test fixtures and trace which line is affected. Often the wrong drain gets snaked because the symptom is downstream.

Step 02

Right tool for the pipe

Branch lines get sectional cable. Mains get a larger machine. Severe cases get camera and possible jetting.

Step 03

Clear & verify

We run the line clear past the blockage and verify with running water from upstream fixtures.

Step 04

Tell you what we saw

If the blockage is recurring or symptomatic of a bigger issue (roots, broken pipe), we explain options.

FAQ

Drain & sewer FAQ.

Should I use a chemical drain cleaner first?
We do not recommend it. Most over-the-counter drain cleaners are sodium hydroxide based and can damage older cast-iron pipe (common in Holliston, Sherborn, and Weston homes) and corrode metal traps. Mechanical cleaning is faster, safer, and more thorough.
What's causing my main drain to back up?
Most main-line backups in older Metrowest neighborhoods are tree-root intrusion, settled pipe sections, or grease buildup at fittings. We diagnose with a sewer camera when needed and clear with the right machine for the size of pipe.
Do you offer hydro jetting?
For commercial and severe residential blockages, yes — typically through a service partner with the right truck. For most residential calls a properly sized cable machine is the right tool.
Can roots really break through my pipe?
Yes, especially in older clay or cast-iron sewer mains. Tree roots seek moisture and exploit the smallest joint. We can root-cut, then recommend whether the section needs longer-term repair.
