  • Basements older than a century

    The city dates South Street homes to 1841 to 1915, and the Stuart district grew in the late 1800s. Many of those basements are brick or fieldstone laid in soft lime mortar.

  • Lots of old housing

    About 3 in 10 homes in the city were built before 1940, so worn masonry basements are common across the older neighborhoods.

  • Freeze and thaw

    Michigan's code rates weathering as severe. Water that soaks into mortar and brick freezes and expands each winter, breaking off a little more each year.

What you will notice

Crumbling walls wear down slowly, so it is easy to miss until a lot is gone. Look for:

Sand on the floor

A small pile of grit along the base of the wall.

Mortar you can scrape out

A key or screwdriver digs into the joint easily.

Deep, empty joints

The mortar has worn back far behind the face of the brick.

Flaking brick faces

Brick surfaces peel or pop off in thin layers.

Loose bricks or stones

A unit wiggles or has fallen out.

White, fuzzy powder

Salts left behind by water moving through the wall.

Damp, dark patches

Wet areas that stay after rain or melt.

Bulging or leaning sections

Part of the wall pushes out of line.

Why Kalamazoo basement walls crumble

They are old. About 3 in 10 homes in the city were built before 1940. In the Stuart, Vine and South Street areas, many homes date to the late 1800s. Their basements were built from brick, fieldstone or early block.

The mortar was made soft. Mortar from that era was mostly lime and sand. The National Park Service notes that repair mortar should be softer than the brick or stone, so the joint wears instead of the brick. That softness is good for the wall, but after a century of water and frost, the joints give out.

Water moves through them. Old basements were not built with modern drains or coatings. The common Kalamazoo soil is loam and clay loam on top, and it holds water against the upper wall. Water soaks through the mortar, carries salts out and leaves white powder behind.

Frost works on wet mortar. Michigan's code rates weathering here as severe. Wet mortar and brick freeze and expand each winter, and a bit more breaks loose every year.

When it is wear and when it is urgent

Normal wear. A little sand on the floor. Joints worn back slightly. The wall is straight and solid.

Plan a repair. Joints are worn back deep enough that you can see shadows in them. Brick faces flake. Water comes through after storms.

Have it checked soon. Bricks or stones are loose or missing. Part of the wall bulges or leans. There are cracks through the bricks, not just the mortar. Floors above that wall have started to sag.

How it is usually fixed

The contractor we connect you with should match the repair to an old wall, not treat it like a new one.

  1. Fix the water first. Gutters, downspouts, grading, and sometimes a drain. The National Park Service says repointing will not last if the water problem stays.
  2. Repoint the joints. The crew removes loose mortar to a sound depth and packs in new mortar. For old brick, the new mortar should be softer than the brick.
  3. Reset loose units. Loose or missing bricks and stones are taken out and relaid.
  4. Brace or rebuild bad sections. A section that bulges or leans may need bracing, or may be taken down and rebuilt.
  5. Coat with care. Some walls get a breathable coating or parging after repair. Hard, sealed coatings can trap water in old masonry.

Ask what mortar mix will be used and why. That one choice makes a big difference in how long the repair lasts.

What it costs

The cost table on this page shows typical ranges from Fixr cost guides, not a quote. Most of the price is labor, so it depends on how many square feet of wall need work and how deep the joints are worn.

What to do before the inspection

  1. Sweep the base of the wall so new sand is easy to spot.
  2. Take photos of the worst joints with a ruler for depth.
  3. Note any loose bricks, but do not pull them out.
  4. Check gutters and downspouts on that side of the house.
  5. Note when the wall gets damp: rain, melt or all spring.
  6. Move storage away from the wall so the crew can see it.

Frequently asked questions

Is it normal for an old basement wall to have sandy, crumbling mortar?

Some wear is normal in a wall that is 80 to 150 years old. Old mortar was made soft on purpose. But mortar that falls out when you touch it, deep open joints, or loose bricks mean the wall needs repointing soon.

Can I just patch it with regular concrete or mortar mix?

Be careful. The National Park Service warns that straight portland cement mortar is very hard. In an old brick or stone wall, mortar that is harder than the brick can make the brick crack and flake. Repair mortar should be softer than the brick.

What is the white powder on my basement wall?

It is called efflorescence. Water moving through the wall carries salts out and leaves them on the face when it dries. It shows where water is getting in. Brush it off and watch where it comes back.

Should I paint or seal the crumbling wall?

Paint over a wet, crumbling wall usually peels. It can also trap water in old brick. Fix the water and the mortar first. Ask the crew what coating, if any, suits your wall.

Do I need to fix the water before repointing?

Yes. The National Park Service says the cause, like a leaking gutter or water in the soil, should be fixed first. If not, the new mortar will wear out the same way.
