Look, if you have masonry on your Lexington home, you need to think about waterproofing. This includes brick foundations, stone patios, and chimneys. Waterproofing is not just about keeping things looking good. It is about protecting your biggest investment from serious water damage. Here in Massachusetts, we get all four seasons. The freeze-thaw cycles we experience can really do a number on brick and mortar. Water gets in, freezes, and then expands. After this, you have cracks, spalling, and bigger headaches later on.
Before You Start: Inspect and Prepare
Before you even think about grabbing a can of sealer, you must do some detective work and get things ready. This is where you can save some money by doing it yourself.
- Check for Damage: Walk around your property and really look at your masonry. Are there any cracks in the brick or mortar? Are pieces flaking off, chipping, or crumbling? That is called spalling. Spalling is a clear sign that moisture is getting in. Even hairline cracks can let water seep in. This only gets worse when it freezes. Look for loose bricks or mortar joints that are deteriorating.
- Spot the White Stuff (Efflorescence): Do you see any white, powdery, or fluffy deposits on your brick or concrete? That is efflorescence. It is basically salt that water has pulled out of your masonry. The salt is left behind when the water evaporates. Efflorescence is not harmful itself. However, it is a clear sign that water is moving through your masonry. This means you have a moisture problem that needs addressing in Lexington.
- Clean Everything Up: You cannot waterproof dirty masonry. Sweep or dust off any loose dirt and grit. For a deeper clean, you might need a stiff brush and some soapy water. You might even need a pressure washer for tougher grime. If you have algae or other growth, a mild bleach solution (half to one cup per gallon of water) can work. Always test it in an inconspicuous spot first. Make sure to remove any efflorescence with a stiff brush and plain water. Rinse thoroughly. If you leave those dissolved salts, they will just come back.
- Address Drainage: This is very important, especially in Lexington. We have our share of stormwater issues. Proper drainage is important. Make sure your gutters are clean. Make sure your downspouts are directing water away from your foundation. If water is pooling around your foundation, or you have consistently soggy spots, you might need to think about regrading your yard. You might even need to install a French drain. These are things you can often tackle yourself or with a good landscaper.
During the Project: DIY vs. Pro
Once your masonry is clean, dry, and repaired, you are ready to waterproof. This is where you need to decide if it is a DIY job or if it is time to call in All Star Masonry Inc. for your Lexington home.
What You Can Realistically DIY:
For minor issues or as preventative maintenance on solid, undamaged masonry, applying a breathable masonry sealer is a good DIY project.
- Choose the Right Product: You will want a breathable masonry water repellent. These products create a barrier against water. They still allow the masonry to
