Chimney with a ladder set up for service, similar to homes throughout North St. Paul, MN

ASH Chimney has worked in North St. Paul since 2014, and it's one of the neighborhoods where our experience with older masonry really matters. Built up around its old rail depot and shoe-factory history, North St. Paul has a lot of early-1900s housing stock with original brick chimneys that have been standing for the better part of a century. We know these homes, and we know how to work on them without cutting corners.

North St. Paul's older, working-class housing stock means original masonry chimneys are the norm here, not the exception, and they've taken on more punishment than most. Minnesota's deep freeze-thaw winters mean a steady load of moisture working its way into brick and mortar every single year. That freeze-thaw cycle is what causes spalling brick, crumbling mortar joints, and failing crowns, and after 80 or 100 years, a lot of North St. Paul chimneys are due for a relining or a partial rebuild rather than a simple patch.

We start every job with an honest inspection, following NFPA 211 guidelines, performed by professionally trained technicians who know what decades of Minnesota winters do to a masonry chimney. If repair work is needed, you get a written estimate first, and the price is flat-fee, no surprises once we're up on the roof looking at what the weather has actually done to your chimney.

FAQs

North St. Paul's older, close-set housing stock means original masonry chimneys are still the norm rather than the exception, and decades of Minnesota's deep freeze-thaw cycling have worked on them longer than on most newer-built suburbs. That combination is why spalling brick, crumbling mortar, and failing crowns show up here more often than elsewhere in the metro.

That's spalling brick, and it's caused by water getting into the masonry, freezing, and expanding until it pushes the surface of the brick off. It's extremely common on North St. Paul's older homes given decades of Minnesota winters. Depending on how far it's progressed, the fix ranges from repointing the mortar to a partial rebuild, and we'll give you a written estimate before doing either.

Yes, relining is one of the more common repairs we do in North St. Paul, since a lot of the original flue liners in century-old homes have deteriorated or were never up to current standards. We'll inspect the liner, explain what we find, and give you a flat-fee written estimate before any work starts.
