Chimney Restoration & Relining

We Proudly Use Guardian Chimney Liners®

The revolutionary Guardian Chimney Liner® is the safest and most effective way of relining masonry chimneys. Using the “cast-in-place” technique, the Guardian system actually eliminates the need to tear down and rebuild an existing chimney, resulting in substantial savings.

How Guardian Chimney Liners Work

Poured into place within an existing chimney, the Guardian mixture hardens to form an extremely durable seal between hot flue gases and the masonry walls. The Guardian Chimney Liner® is designed to withstand extremely high temperatures without cracking or breaking down. It is an excellent insulator against excessive and dangerous heat transfer from the chimney to the surrounding structure.

 

In fact, test results prove that the Guardian system is a better insulator than any other kind of flue liner of its kind. This system also retards the absorption of condensation and the buildup of dangerous and flammable creosote within the chimney flue.

Additional Benefits

As the Guardian mixture is poured into place, it fills in all cracks, crevices, and pores in the existing flue area. This tight, virtually perfect seal helps prevent the leakage of any toxic flue gases into the living area. This seal also fills and reinforces brick joints in the chimney structure, locking them into place and strengthening the entire chimney.

 

Additionally, this lining material is highly resistant to damage caused by the natural “freeze-thaw” cycle which is responsible for much of the damage to highways, bridges, and similar structures. In fact, laboratory tests revealed no evidence of surface deterioration when subjected to these extremes.

Versatile and Durable

The Guardian Chimney Liner® is ideal for use with almost every form of heating appliance, whether it burns wood, coal, gas, or oil. The liner is poured to precise specifications so that the actual finished flue is properly sized for the individual heating appliance. A Guardian liner makes your chimney safer, more efficient, and extremely resistant to corrosion and deterioration. You simply cannot buy anything better to safeguard your chimney.

 

The Guardian System also allows you to safely create two or more flues within one large chimney space, eliminating the need to vent two heating appliances into the same flue. This revolutionary system is the safest and most effective way of relining masonry chimneys. Using the “cast-in-place” technique, the Guardian system actually eliminates the need to tear down and rebuild an existing chimney, resulting in substantial savings.

Installation Procedure

The chimney is first inspected and cleaned using standard chimney sweep procedures and equipment. Chimneys that have suffered fire damage often have cracked or broken tiles. All lower openings in the chimney structure are closed off and any weak areas in the chimney are braced. All of the existing tiles are then removed from the chimney, ensuring a large cavity in which to size and pour the new liner.

 

Next, an inflatable rubber former is inserted into the chimney cavity, centered with spacers to ensure proper flue wall thickness, even along offsets or bends with the flue path. The Guardian mixture is prepared on site by simply adding water. The mixture is then poured into the chimney from the top so that it flows around the form, between it and the chimney wall, filling the entire cavity.

 

When the Guardian mixture hardens, the former is deflated and removed, leaving a smooth, round, efficient flue passage. The new Guardian liner even shields the walls of the chimney’s smoke chamber. With proper maintenance, your Guardian Chimney Liner® will provide many years of service. Finally, the top of the chimney is finished off with a crown.

Had the Mad Hatter clean out our dyer vent today. They were on time! The technician, Josh & Dennis were very professional and knowledgeable about doing the job correctly in a timely manner and answering my questions too. They were very considerate of making sure they did not bring in or leave any dryers lint anywhere. They lay down a mat at the inside of it home and made sure they wore shoe covers when entering the home. I will certainly be using them again. Also, I would recommend The Mad Hatter to my family, friends, neighbors any anyone else needing their services.

I am 150% satisfied with the work done by The Mad Hatter to restore my fireplace & chimney to working condition. The initial estimate and restoration work were done by Juan Carlos and his team (Juan Carlos Jr, Oscar and Tino). The estimate accurately reflected the time and effort needed to fix the numerous problems due to almost 50 years of use, neglect and sub-standard original construction that did not meet the fire code. From day one, the crew was extremely careful not to create a mess in my house by wearing plastic booties, laying carpet runners & blankets, covering all the furniture with plastic and erecting a temporary plastic enclosure around the fireplace to contain the dust & debris. An exhaust fan ducted out a window minimized any dust getting into the house. They removed all the damaged fire bricks in the fire box, the rusted-out damper, and the deteriorated terra cotta flue. Then, they replaced the fire brick in the firebox, parged the smoke box, and installed a new stainless-steel flue. On the exterior, they removed & replaced all the missing/deteriorated brick & mortar on the chimney chase, raised the height of the chimney chase to meet the fire code 10-2 requirement, fixed the old flashing, installed a top damper and custom-built hip cap. The entire chimney chase was sprayed with a sealant. What warrants the extra 50% was all the extra things done over and above the contracted work to ensure I was completely satisfied like providing daily status updates with photos, installing a new gas log starter and fire grate, adding hardy plank between the studs in the attic adjacent to the chimney chase to replace gypsum siding deteriorated by water leaking around the old chimney flashing, adding metal caps to the shoulders of the chimney chase to repel water, thoroughly raking and sweeping the yard of brick debris, adding new mulch to the flower bed at the base of the chimney, and even screwing a piece of metal over a hole that a squirrel had chewed into my attic at the corner of the eave that I could not reach with my extension ladder. Thank you for a superb job done by an extremely professional and courteous crew. I highly recommend them for any fireplace/chimney inspection and/or repair needed.
