Your chimney liner is the only barrier between combustion gases and
your home's framing and living spaces.
your home's framing and living spaces.
A cracked, deteriorated, or absent liner is a fire and CO poisoning waiting to happen.

The liner contains combustion gases and channels them safely out of your home. Without an intact liner, CO and superheated gases have a direct path into your living space and combustible framing — both invisible killers.

NJ and national codes require a properly sized, intact liner for all fuel-burning appliances. A documented liner installation from a licensed NJ contractor satisfies inspectors, insurance reviewers, and home buyers.

A correctly sized stainless steel liner improves draft, reduces creosote buildup, and lets your furnace, boiler, or fireplace run at full efficiency — which shows up directly in your heating bills every month.

Stainless steel flexible liners are engineered for continuous thermal expansion and contraction through NJ freeze-thaw cycles. They outlast clay tile liners by decades — with no cracking, no spalling, no deterioration.

We call you back within 24 hours to schedule your free on-site estimate. No pressure, no commitment.

Most liner installations completed in 1 day. We pull the permit, schedule the required inspection, and handle all documentation.
Stainless steel flexible liner installation in NJ typically runs $1,500–$4,000 depending on flue height, flue diameter, liner gauge, and whether insulation wrap is required. More complex installations cost more. We provide free, detailed written estimates.
A chimney liner is a protective conduit inside your chimney flue that channels combustion gases safely out of your home, protects surrounding masonry from heat and corrosive combustion byproducts, and prevents fire and CO gases from entering your living space. NJ and federal code require a properly sized, intact liner for every fuel-burning appliance.
We install stainless steel flexible liners (most common and recommended for NJ homes — durable, code-compliant, handles all fuel types), rigid stainless for straight flues, and cast-in-place liners for severely damaged or irregularly shaped flues. We assess your flue and recommend the right system.
Most residential liner installations are completed in 1 day. More complex projects — insulated wrap required, large-diameter flues, flues with severe debris or tile collapse — may take 2 days. We give you a precise timeline in your written estimate.
Yes — in most NJ municipalities, a permit is required for chimney liner installation. A1 Apex handles all permit coordination and scheduling of the required final inspection at no additional charge. We don't skip this step.
Cheaper liner quotes often mean undersized diameter (creates poor draft and allows CO to back up), uncertified materials that don't meet NFPA 211 standards, no insulation wrap where required, or installation by someone without chimney-specific training. CO is odorless and colorless. A chimney liner is not the place to find the lowest bid.
