Drain cleaning in Milford, MA

Cornerstone Plumbing clears clogged and slow drains for homes and rental properties in and around Milford, Massachusetts, and looks for the cause so the clog doesn't come straight back. Call (508) 361-9450 and tell us which drains are affected. One drain or several makes a big difference.

What we handle

Why does my drain keep clogging?

A drain that keeps clogging usually has buildup further down the line than a plunger reaches, such as grease, hair, soap or tree roots, or a pipe with a sag or damage that catches debris. Cornerstone Plumbing clears the line and looks for the underlying cause, so you aren't calling a plumber for the same clog every few months.

How do I know if it's my main line?

If several fixtures back up at once, the lowest drain (often a basement floor drain or shower) overflows, or toilets gurgle when the washer drains, the clog is probably in the main line, not one fixture. Stop using water and call Cornerstone Plumbing at (508) 361-9450. Main line clogs need professional equipment.

What should I do if the sewer backs up into my basement?

Stop using all water in the building, keep people and pets away from the sewage, and don't touch it without gloves. Turn off electricity to the area if you can do it safely. Photograph the damage for insurance, then call Cornerstone Plumbing at (508) 361-9450 to clear the line and find the cause.

Are chemical drain cleaners safe for my pipes?

Chemical drain cleaners can damage older pipes and fittings, rarely clear a clog that's deep in the line, and make the job hazardous for whoever opens the drain next. For a stubborn or recurring clog, Cornerstone Plumbing recommends calling a plumber instead. Tell us if you've already used a chemical cleaner.

Does Cornerstone Plumbing do sewer camera inspections?

Yes. Cornerstone Plumbing has a sewer camera and runs it through main and sewer lines to see what's causing a clog or backup, such as tree roots, a sag, or a broken or separated pipe. Seeing inside the line means the fix matches the actual problem instead of a guess. Call (508) 361-9450 to book one.

How much does it cost to unclog a drain?

It depends on which drain is clogged, how far down the clog is, and whether the main line is involved. Cornerstone Plumbing charges a flat rate by the task, not by the hour, plus a diagnostic and dispatch fee. The price also depends on how far the property is from Milford, and you hear it before work starts.

How soon can Cornerstone Plumbing come out?

Cornerstone Plumbing can usually come out the next day. A same-day visit is sometimes possible when the schedule allows, with an added fee for moving other jobs. For a true emergency outside Monday–Friday, 8:00 AM–5:00 PM, Cornerstone offers 24-hour emergency service with an after-hours fee. Call (508) 361-9450 to check the schedule.
