Some Of The Many Chimney Repair And Masonry Services We Can Help With

Firebox Repair
If years of use have taken their toll on the mortar joints or firebrick in your firebox, Guaranteed Chimney Service can bring it back to its former glory. Tuckpointing work and firebox rebuilds are two of our specialties!

Chimney Crowns
The chimney crown is an important part of your system’s protection against water, so a cracked or spalling crown can quickly lead to water damage. If your crown has seen better days, call Guaranteed Chimney Service – we can assess the damage to your crown and suggest the best repair approach, from a crown coat sealant to a full crown rebuild.

Chimneys Relined
Your chimney’s liner is protecting your masonry and your home from dangerous gases and high heat. The liner is also an important part of your chimney’s function — for adequate draft, a properly-sized liner is a must. If your liner is damaged, missing, or incompatibly-sized for your appliance, Guaranteed Chimney Service can help. We install all kinds of liners, from stainless steel to cast-in-place.

Oil & Gas Relining
Your oil and gas appliances need a proper flue liner just as much as wood-burning appliances do, and checking for proper flue sizing when replacing an old boiler or water heater with a new one is of particular importance. If you’re unsure of the condition of your oil or gas flue liner, give us a call today!

Chimney Leaks
Guaranteed Chimney Service technicians know chimneys inside and out — we can inspect your chimney to find the issues contributing to leaks, and make the necessary repairs so that you can enjoy a safe chimney and a dry home.

Waterproofing
Having a waterproofing sealant applied to your masonry can help you avoid leaks and protect your masonry to give it a longer service life. Talk to our technicians about the benefits!

Flashing
Damaged flashing is a common cause of chimney leaks, since flashing is protecting the chimney at one of its most vulnerable areas (the place where the chimney and roofline meet). Guaranteed Chimney Service’s technicians do the detailed, custom work of installing and repairing chimney flashing every day — if your flashing is damaged, we can help!

For all your chimney and masonry repair needs, call Guaranteed Chimney Service. Our experienced technicians can help!

 

Since you can’t see its inside surface, you may not know whether your chimney needs to be relined. That’s just one of the issues that can be uncovered with regular chimney inspections and service.
