As a consequence, SBC cannot vouch for the validity of any facts, claims or opinions made in the article. Q: After noticing some bubbled paint inside my home under a few windows, I did an inspection of the outside of my home and discovered holes in the mortar of my brick window sills.

Too often, people ignore warning signs until they develop into serious problems. One could easily write a book about the topic. I find that people tend to believe brick structures are waterproof. The truth is that water enters into brick walls with relative ease.

Many modern brick homes and some commercial buildings are built with a brick veneer. This means the brick is just one wythe thick. The brick is just a facade and offers no structural support whatsoever.

We are constructing 2 x 4 walls on the interior, parallel to the brick, but not touching or attached. We expecting to run our electric in those walls and insulate. That hopefully will allow the brick to continue to breathe. And you say the bricks have been done the job of bricks since and that they are in good enough condition to reuse today? Ignore the mason - he's trying to line you up for his next job repairing bricks that fail: Thank your lucky stars that sealing products weren't around in We reused bricks on our home and there is no way we would seal them - not 5 years ago when the work was done and not today.

If the sealer holds moisture in the brick and it than freezes it will spall the face of the brick. If the insulation is poor and the brick face never reaches freezing from heat escaping nothing might happen. Thanks to all that have responded.

Yes, most of the bricks on the home are still in great shape years after they were made We were fortunate to have bricks available from an internal chimney that had to be removed. Those were used to make the few repairs needed.

We'll be following your kind advice and leaving our home unsealed. To begin with, it is important to understand that waterproof coatings and water-repellent coatings are not the same. Although these terms are frequently interchanged and commonly confused with one another, they are completely different materials.

Water-repellent coatings--often referred to incorrectly as "sealers", but which do not or should not "seal"--are intended to keep liquid water from penetrating the surface but to allow water vapor to enter and leave, or pass through, the surface of the masonry. Water-repellent coatings are generally transparent, or clear, although once applied some may darken or discolor certain types of masonry while others may give it a glossy or shiny appearance.

Waterproof coatings seal the surface from liquid water and from water vapor. They are usually opaque, or pigmented, and include bituminous coatings and some elastomeric paints and coatings.

If porous brick can't dry in areas with frequent and severe freeze-thaw weather cycles, it will cause the brick face to spall. Therefore, a waterproof "sealer" would increase the risk of damage.

In order to show the structure at its best, the contractor should take the following three steps before sealing the masonry:. Weathering and age take their toll on masonry. The most common damage is deterioration of the mortar joints. Repointing mortar that is missing or damaged will improve the appearance and structural integrity of the wall.

Similarly, cracked or missing brick or stone pieces should be replaced at this time. Finding brick to match the existing masonry can be difficult, so this issue should be addressed as soon as possible. When an exact match cannot be found, or is impractical for a particular job, the contractor should find a substitute of the same size and texture, and as close as possible to the original wall in color.

Exact coloring can be adjusted later in the process. Both of these resources can be accessed through the online version of this article at www. In cleaning brick and stone, the contractor should use the gentlest method that will still get the job done. Sometimes a bucket and brush are the only tools needed. Algae and other growth can be removed from masonry, and should be prior to the application of sealant. One approach that is often successful is a mild bleach solution: half to one cup bleach per gallon of water.

As with any cleaning solution, this should be tested ona small area first for success before doing a large area. Efflorescence and other staining can be treated using specialty cleaners.

However, these solutions are best if they are specifically manufactured for the brick or other masonry utilized. The brick dealer or manufacturer will usually be able to provide specific advice. You desire brick because it is durable, maintenance-free, good-looking, provides texture and it is waterproof. Not bad, you got four out of five. Brick is not waterproof. In fact, many, many brick veneer houses built today leak and leak badly.

Fortunately, there are simple ways to redirect this water back outside. Virtually every brick wall will allow water to penetrate. The water has three possible paths. The primary path of water into brick walls is the contact zone between brick and mortar and mortar joints. The vertical joints between individual brick are rarely solid. This is water's entry place. The quality, type, and moisture content of the mortar is a critical factor in preventing brick veneer wall leaks.
