Your stacks are failing. Replacement means opening walls, relocating residents, and a schedule nobody on your board wants to approve. Clear Pipe Solutions restores commercial drainage from the inside using cured-in-place pipe lining. The building stays occupied. The walls stay closed.
Every property manager who has replaced a cast iron stack knows the real cost, and it is not the pipe. It is the drywall. The flooring. The units taken offline. The residents who need somewhere else to sleep. The general contractor coordinating four trades around one plumber. By the time the line is back in service, the plumbing invoice is a fraction of what the project actually cost.
Cured-in-place pipe lining removes most of that. A resin-saturated liner is installed through existing access points, pressed against the interior wall of the failing pipe, and cured in place.
What remains is a jointless structural pipe inside the old one. The corrosion has nowhere to continue. The cracks and separated joints are sealed. Flow improves because the new interior surface is smooth where the old one was scaled and pitted.
The distinction that matters for commercial work is structural versus cosmetic. A brush-applied epoxy coating fills pits and slows corrosion. It does not carry load. A properly installed CIPP liner is designed to function as a standalone pipe, which is what a building needs when the host pipe has already lost significant wall thickness.
Clear Pipe Solutions does commercial work only. Not because residential work is beneath us, but because occupied commercial buildings, high-rise stacks, and Sovent systems require different equipment, different access planning, and different scheduling than a house does. Specializing is the reason we can line a stack in a fully occupied building without the property losing a floor for a month.

By the time backups become routine, the pipe wall has thinned, channeled along the invert, and lost the diameter it needs to carry the building’s load. Lining restores structural integrity and flow without opening the chase.
Stacks fail differently than horizontal lines. Constant flow, aggressive waste, and decades of scale attack the same surfaces. Replacing a stack means working floor by floor through occupied units. Lining is installed through existing access and cures in place, top to bottom.
Underground commercial laterals shift as the ground settles. Joints separate, roots enter, and every cleaning buys a few more months. A liner eliminates the joints entirely, which eliminates the entry points.
Sovent single-stack systems are engineered assemblies, not ordinary DWV. Most contractors have never worked on one. Clear Pipe Solutions specializes in Sovent, which means we can restore the stack without compromising the aerator and deaerator fittings the system depends on.
Every project begins with camera inspection. We locate the damage, measure remaining wall condition, map access points, and confirm whether the host pipe can support a liner. If it cannot, we say so before anyone signs anything.
A liner bonds to what it touches. Scale, tuberculation, grease, and root mass all come out first using mechanical cutting, specialized mechanical cleaning, or both depending on what the inspection found. This step is where most failed lining jobs actually fail.
The resin-saturated liner is installed through existing access points and pressed against the pipe wall under pressure. It cures in place, forming a jointless structural pipe inside the original. Curing method and duration are matched to the pipe, the system, and the building’s schedule.
We re-inspect the finished line on camera and deliver a documented record: pre-condition, work performed, and post-cure verification. Boards, insurers, and reserve study consultants get evidence, not a description.
Cast iron drainage was standard in commercial and multifamily construction for decades. Cast iron drainage was standard in commercial and multifamily construction for decades.
The failure pattern is consistent. Backups become more frequent. Cleanings that used to hold for a year hold for a quarter. A stack that was cleared last spring is clearing slowly again. Maintenance budgets absorb the recurring cost until someone runs the math and realizes the building has been paying to manage a failure rather than fix it.
There is also a timing problem specific to commercial property. Stack failures rarely announce themselves during business hours. They announce themselves at three in the morning, on a holiday weekend, through the ceiling of an occupied unit, and the conversation that follows is about liability rather than plumbing.
Lining changes the timeline. Because the work happens inside the existing pipe, a rehabilitation project can be scheduled around occupancy, seasonal patterns, and capital cycles instead of triggered by an emergency. That is the difference between a planned expenditure and an insurance claim.
Clear Pipe Solutions mobilizes to commercial properties nationwide. Ownership groups with buildings in multiple markets get one specification, one process, and one point of accountability across the portfolio.

Recurring backups are a symptom. Lining addresses the pipe.
When a line backs up again on a shortening cycle, cleaning is no longer maintenance. It is a subscription to a problem. Camera inspection determines whether the pipe has lost enough wall to justify lining.
Boards and ownership groups need defensible numbers for infrastructure that has not failed yet. A documented condition assessment lets you put pipe rehabilitation in a reserve schedule instead of an emergency line item.
Drainage condition is one of the least examined and most expensive variables in a commercial transaction. Documented pipe condition supports the valuation conversation in either direction.
Carriers are increasingly attentive to buildings with repeat water loss claims. A documented rehabilitation of the failing system is a concrete answer to underwriting questions about recurrence.
A liner needs a host pipe stable enough to hold it. Not every failing line qualifies, and recommending lining for a pipe that cannot support one is how buildings end up paying twice.
In those cases we recommend spot repair, partial replacement, or full replacement, and we explain what the camera showed to support the recommendation. A proposal built on an inspection you can watch is worth more than a proposal built on a symptom description over the phone.

CIPP stands for cured-in-place pipe. A resin-saturated liner is installed inside an existing damaged pipe and cured, forming a new jointless pipe within the old one. The result is a structural repair that does not require excavating or demolishing to reach the original line.
Commercial systems carry more volume, run through occupied vertical space, and often include engineered assemblies like Sovent single-stack drainage. The equipment, access planning, and scheduling all differ. Clear Pipe Solutions works exclusively on commercial properties.
Yes. Vertical stack lining is installed through existing access points, which is the reason it can be completed without floor-by-floor demolition. Occupancy planning is part of the pre-project scope.
Liner material warranties and expected service life depend on the product, the host pipe condition, and the system being restored. We provide the specific warranty terms for your project in the proposal rather than a general figure.
The affected line is taken out of service during installation and curing. Duration depends on the pipe and the curing method. Sequencing to minimize disruption is planned before mobilization, and for most commercial projects the building continues operating throughout.
Cast iron, clay, concrete, PVC, and other common commercial drainage materials are frequently candidates. Condition matters more than material. A camera inspection determines whether a specific line qualifies.
Yes. Sovent is a core specialization for Clear Pipe Solutions. Sovent systems depend on aerator and deaerator fittings functioning as designed, which is why restoration requires a contractor who understands the system rather than one treating it as conventional DWV.
A project record including pre-condition camera footage, work performed, and post-cure verification video. It is built to be usable in board packages, reserve studies, insurance files, and transaction due diligence.
Nationwide. We mobilize to commercial properties anywhere in the country.
No. Clear Pipe Solutions serves commercial and multifamily properties only.
Commercial pipe lining rehabilitates failing drainage without the demolition, displacement, and downtime that replacement requires. It starts with a camera inspection that tells you what is actually happening inside the line, and a recommendation you can put in front of a board.
