Can you always get an exact brick match on an old home?

Not always. Older brick changes color and texture as it weathers, and many older runs are no longer made. The goal is a match that reads naturally from a normal viewing distance, not a perfect lab match.

Why does the type of mortar matter so much on older homes?

Older homes were typically built with softer, lime-based mortar. Using a harder modern mortar on those walls can shift stress onto the brick and lead to spalling. The mortar should match the original in both look and behavior.

What is the difference between a brick match and a mortar match?

A brick match means choosing replacement brick that blends with the existing wall in color, size, and texture. A mortar match means tuning the new mortar's color and joint profile so the new joints look like the old ones. Most restoration projects need both.

Do you do test patches before doing the full repair?

Yes. On almost any older home, a small test patch in a low-visibility spot is the only honest way to know how the mortar and brick will look after they cure and weather a bit.

Matching Brick and Mortar on Older Homes

Older brick homes around Metro Detroit have a look that is hard to fake. The brick has weathered for decades. The mortar has softened. The joints have aged into the wall. When part of that wall needs repair, the job is not just about making it strong again. It is about making the repair disappear.

We do a lot of this kind of work in older neighborhoods around Birmingham, Royal Oak, Rochester, Huntington Woods, Ferndale, parts of Detroit, and similar areas. This article walks through what brick and mortar matching actually involves and why exact matches are not always possible.

Why older brick is hard to match

Bricks made 80 or 100 years ago were often local. Color and texture varied based on the clay, the kiln, and the run. Two pallets from the same plant could look noticeably different. On top of that, a brick wall that has been outside in Michigan weather since the 1920s does not look anything like new brick from the same recipe.

Common challenges include:

The original run is no longer made
The brick has weathered into a color that fresh brick does not match
The size is slightly different from modern standards
The face texture is rougher, smoother, or sand-faced in a way that is hard to source today
The original brick may have come from more than one batch and varies across the wall

How we approach a brick match

Look at the whole wall, not one brick. Older walls usually have a range of brick tones. A good match picks up the mid-range of that range, not the lightest or darkest brick in the field.
Pull a sample if possible. A spare brick from an attic, basement, garage, or hidden run gives us the cleanest reference. Without a sample, we work from photos and on-site comparison.
Check local salvage and reclaimed sources. Reclaimed brick from a similar era often blends better than new brick, especially on pre-war homes.
Match size, texture, and face direction. Even when the color is close, the wrong size joint or the wrong face can make a repair stand out.

Why mortar color matters as much as brick color

Most of what the eye reads on a brick wall is actually the mortar. The lines between bricks are a major part of the visual pattern. A small color mismatch in the mortar can make a perfect brick match look obviously patched.

Mortar color comes from three things:

The sand used in the mix
The binder (lime, cement, or a blend)
Any pigments added for color tuning

We sample the original mortar by pulling a small piece from a hidden joint and breaking it open. The inside color is the true color, not the weathered outside. From there we adjust sand and pigment, then run a test patch.

Joint profile matters too

Two walls with the same brick and the same mortar color can still look different if the joint profile does not match. Concave joints catch shadow differently than struck or flush joints. On older homes, the joint may also be raked, weathered, or slightly recessed. We match the joint profile to the rest of the wall so the new mortar reads as part of the original pattern.

Why exact matches are not always possible

Sometimes the original brick simply is not available, and the closest reclaimed option is still off by a shade or two. Sometimes the original mortar contained materials that are no longer common. When that happens, we tell the homeowner directly. The goal becomes a careful blend that looks natural from a normal viewing distance, rather than a perfect lab match.

On a well-matched restoration, you can stand across the street and see a clean, continuous wall. Up close you may still see a slight difference. That is a normal trade-off on older brick.

Why we run test patches

Mortar dries lighter than it looks when wet. New brick deepens slightly as it weathers. The only way to know what a repair will actually look like is to do a small test patch in a low-visibility spot and let it cure for a few days. We almost always do this on an older home before committing to the full repair. It saves frustration on both sides.
