New England weather is brutal on brick and mortar, and if you live around here long enough, you already know what a hard winter does to masonry. Every year around February, All Star Masonry Inc receives calls from homeowners off Marrett Road or down near the Battle Green staring at piles of red dust and crumbling mortar joints on their front steps. Here is the straight truth about how our local climate impacts bricklaying, when you should actually schedule your projects, and what you can do right now to keep your masonry standing strong for 15 to 20 years or more.
Why Lexington Weather Punishes Brickwork
Our local climate in Lexington, MA is basically a giant sponge followed by a massive freezer. We get heavy nor'easters, soaking spring rains, and relentless humidity in July. Brick is naturally porous, meaning it drinks up that moisture like a dry sponge. When autumn turns into winter, all that trapped water freezes and expands. That expansion exerts massive pressure on the surrounding mortar. Something has to give, and usually, it is the mortar joints popping right out. All Star Masonry Inc also deals with heavy clay soil throughout most of Lexington, which shifts dramatically during the freeze-thaw cycles and puts extra stress on foundational brick and stone walls.
Timing Your Masonry Projects
You cannot lay brick just any old time of year up here. Mortar needs specific temperature ranges to cure properly, and the local climate does not always cooperate. Summer is great, but the scorching July heat can dry out mortar too fast, making it weak and crumbly. That is why professional masons prefer late spring and early autumn. During these windows, the air is crisp, the humidity is manageable, and the mortar cures at a steady, ideal pace. If you are planning a patio, a new chimney rebuild, or a brick walkway, aim for May or September. Trying to pour concrete or lay brick when temperatures drop below 40 degrees Fahrenheit without heavy tarping and heated additives is a recipe for disaster.
All Star Masonry Inc constantly turns down late November requests for exterior bricklaying because the freezing nights will destroy the work before the cement even sets. If you missed the fall window, wait until the spring thaw rather than rushing it.
Year-Round Protection Strategies
Protecting your property does not require a degree in engineering, just a little proactive maintenance. Start by checking your gutters every single October. When a gutter overflows right above a brick wall, it dumps gallons of water directly onto your masonry day after day, accelerating decay faster than normal weather ever could.
Next, look closely at your mortar joints. If you see cracks or gaps thinner than a credit card, you might just need some minor tuckpointing. If chunks are missing entirely, water is getting behind the brick face. Applying a breathable siloxane-based water repellent every few years helps keep moisture out while still letting the brick release internal vapor. Never use cheap hardware store silicone sealants that trap moisture inside the brick, because that guarantees winter spalling when the deep freeze hits.
Keep an eye on your chimney crown, too. That concrete cap takes the brunt of every storm rolling across Middlesex County. If it cracks, water leaks straight down into the flue and freezes from the inside out. Fixing a small crack in May is much cheaper than rebuilding a collapsed chimney stack in November.
