Slow drains, sewage backups, clogged main lines, and recurring blockages can turn into a major problem fast. Tandem Mechanical provides fast professional drain and sewer service for homes, businesses, apartments, and commercial properties.
Stop using fixtures connected to the affected drain or sewer line when possible.
Keep people and pets away from sewage or contaminated wastewater.
Do not keep flushing toilets or running water to “test” an active backup.
Call 413-667-4998 and tell us which fixtures are affected, when it started, and whether wastewater is overflowing.

We do not treat every clog the same. Access, pipe condition, blockage type, recurring history, and whether the issue is a fixture drain, branch line, or main sewer all affect the recommended approach.
Mechanical cable equipment can open many common fixture, branch-line, and main-line blockages when the obstruction can be reached and cleared safely.
High-pressure water can remove heavy grease, sludge, scale, and recurring buildup when the piping condition and access make jetting appropriate.
Video inspection can help identify recurring blockage locations, roots, damaged piping, offsets, buildup, or other conditions inside an accessible sewer line.
Restaurants, multifamily buildings, facilities, retail, offices, and managed properties can require larger equipment, access coordination, and preventive drain planning.
The symptoms help narrow down whether the problem is likely at one fixture, a branch drain, or farther downstream in the building sewer. These guides can help you understand the likely next step before service.
When toilets, tubs, showers, or floor drains are affected together, the problem may be farther downstream in a branch or main sewer line.
See Problem GuideA localized clog can build from soap, hair, grease, food debris, or other material inside a fixture or branch drain.
See Problem GuideA toilet blockage may be isolated to the fixture or may be a symptom of a larger drain-line problem if other fixtures are affected too.
See Problem GuideOdors and gurgling can point to drainage, venting, trap, buildup, or sewer-line conditions that should be evaluated instead of masked.
See Problem GuideRecurring kitchen clogs are commonly related to grease, food debris, scale, or buildup in the branch line.
See Problem GuideHair, soap residue, scale, and local branch-line buildup are common causes of shower and tub drainage problems.
See Problem GuideWe respond to backups and urgent drainage problems affecting kitchens, bathrooms, basements, laundry areas, floor drains, main sewers, and residential properties.
Restaurants, multifamily properties, offices, retail, facilities, and managed buildings can require larger equipment, faster coordination, and careful planning around tenants or operations.
Tell us what is backing up, overflowing, draining slowly, or affected. We assess urgency and current dispatch availability.
We help identify immediate steps such as stopping fixture use or isolating the affected area when appropriate.
We evaluate the affected fixtures and drain path, then use cable equipment, camera inspection, hydro jetting, or other appropriate methods based on the condition.
After approved work is completed, we verify drainage or flow and explain what we found, what was done, and any recommended follow-up.
Not every slow drain requires emergency dispatch. These guidelines help customers decide whether to call now or schedule regular drain service.
The right price depends on the actual blockage and the work required to access, diagnose, clear, and test the line. Tandem does not present one generic price as if every drain emergency is the same.
A fixture clog, branch drain, building drain, and main sewer can require different access points, equipment, and time.
A simple obstruction is different from heavy grease, roots, scale, repeated backups, or a line that will not stay open.
Cable cleaning, camera inspection, hydro jetting, root-cutting equipment, cleanout access, and other diagnostic work can affect the approved scope.
Cleanout location, finished spaces, basements, commercial access, multiple units, and site conditions can change how the work must be performed.
After-hours and emergency dispatch can be priced differently from standard scheduled service. We explain the applicable service rate and approved scope before work proceeds.
If inspection identifies damaged, collapsed, offset, deteriorated, or otherwise failed piping, repair or replacement is a separate scope from clearing the blockage.
Before approved work begins: we explain the applicable service rate, what we found, and the recommended scope. Additional repair or replacement work is not treated as part of a basic drain-clearing visit unless separately discussed and approved.
Tandem Mechanical provides drain and sewer service throughout our active Massachusetts and Connecticut coverage areas. We operate as a service-area company and do not claim a physical office in every municipality.
