Chimney Repair and Service

If your chimney needs repair, you can trust Dayco General to get the job done right. Our company has been helping homeowners with safer chimneys. Our technicians are consistently up to speed on the latest technologies and practices.

We believe only brick and stonemasons that know building code and chimney physics should fix chimneys. We not only have a state license, but we have two certifications for chimney repair.

We offer chimney repair and service, which includes any type of repair such as replacing the top of your chimney or a complete chimney rebuild – whatever is needed, we can do it for you! We’re small enough to give personal service but big enough to tackle the largest jobs.

Brick Chimney Replacement

The owner of this home said he had trouble finding a chimney builder that would replace this 50+ year old chimney with the same style as the existing. We were very pleased to take-on this fancy brickwork and it turned out very nice.

Soft Lime Brick Covered With Stucco

Every time we see a brick and stucco chimney in a state of failure, we know that the brick under the stucco has most likely exceeded their useful life expectancy. The best approach that we have found is to plan a complete rebuild from the beginning.

It is not wise to repair these types of stucco and brick chimneys. Our staff will get you the quote for the best repair option.

NY Bluestone Chimney & Chilton Stone Chimney

This chimney beautifully combines NY Bluestone and Chilton stone. On this job, we removed the existing concrete cap (or what is left of it) and the top few layers of stone. We relayed the stone in the new mortar and installed a new stone top. We also fully pointed the rest of the chimney to the roofline. We caulked the flashing perimeter; the owner opted to reject our recommendation to replace the flashing.

Chimney Repair Minneapolis Dayco General

Chimneys can develop cracks and other damage because of many factors with weather being an enormous factor here in the Minneapolis area, over time bricks strain, and mortar joints show wear, time itself also wears on masonry. Our technicians can reverse time and fix all sort of chimney damage. We can replace an eroded throat damper or seal a cracked crown. We also offer annual chimney inspections that will ensure your chimney stays in its best possible condition.

Masonry is highly durable, but it wears down with constant exposure to weather. Masonry joints can deteriorate from cracking to eroding. Bricks have their own life expectancy. Even prefabricated chimney systems will deteriorate with time. We offer a specialty tuckpointing service just for these cases to renew those deteriorated mortar joints. This can extend the life of your chimney substantially.

A properly functioning lining is the most important aspect of your chimney. The liner keeps the high heat away from your home and your home safe from fire hazards. The lining is also what keeps chimney gasses from entering your home. We can help you with any situation regarding the lining of your chimney with a certified lining installed by the most certified professionals.

We Offer A High Level Of Expertise

Having spent over $5,000 for our people to learn about chimney physics and engineering, our certifications include Master Cement Finisher & Master of Masonry, (Minneapolis registry, #M127), and two certifications from the Ahrens School of Masonry Restoration and Chimney repair. We are certified by The Chimney Safety Institute of America.

We offer a full range of chimney repair services including complete rebuilds, rebuilding from the roof up, chimney lined replacement, tuck pointing, installing flue top dampers, and minor repairs.

Attention To Detail

The little things we do make a big difference. For example, we use a comprehensive guide to match our mortar colors to the existing mortar on your chimney.

Prevent Water Leaks

We inspect the flashing around your chimney to make sure it’s code compliant. If it’s not, we strip down all remnants of the old flashing down to the roofing underlayment and then do a proper “build-back” with a complete, three-part system that is guaranteed not to leak.
We put a drip ledge on your chimney cap so that water doesn’t run straight down the side.

Increased Protection Against Chimney Fires

We always use fire-resistant refractory mortar when installing clay tile flue liners.
We isolate chimney flues from the cap so that they have room to expand without creating cracks that could lead to chimney fires.

Extend The Life Of Your Chimney:

We build your chimney cap out of specially modified concrete. This makes our caps far superior to the concrete chimney caps that are typically installed.
As a result of our continuing education in the latest concrete techniques, we also use a special additive to further strengthen our concrete caps.

“The repairs look great, Dave. You have some genuine craftsmen on your team. … We thought the cost very reasonable, as well.”
