Trusted Somerville Chimney Company

We Know Somerville's Chimney Challenges

We’ve been fixing chimney leaks in Somerville and the greater Boston area for over 30 years. We understand how brutal Massachusetts winters are on your chimney—the freeze-thaw cycles that crack mortar, the ice dams that force water into places it shouldn’t go, and the constant exposure that wears down even the best materials.

We’re a family-owned company, which means we actually live here too. We see the same weather patterns you do. We deal with the same old housing stock, the same building codes, and the same contractors who cut corners.

That’s why we don’t just patch the obvious problem and walk away. We dig deeper to find the real cause of your leak, fix it right the first time, and make sure it stays fixed.

Our Chimney Leak Repair Process

Here's Exactly What We Do

First, we thoroughly inspect your entire chimney system—not just the obvious wet spots. We check the crown, flashing, mortar joints, and interior components to identify every entry point where water is getting in.

Then we explain what we found in plain English. No technical jargon, no scare tactics. Just the facts about what’s broken, why it’s leaking, and what it’ll take to fix it permanently.

The actual repair depends on what’s causing your leak, but most jobs involve replacing damaged flashing, resealing the chimney crown, or repointing deteriorated mortar joints. We use materials specifically designed for New England weather—stuff that won’t crack, shrink, or fail when the temperature drops.

We clean up completely when we’re done, and we’ll walk you through what we did so you understand exactly what you’re getting for your investment.

What's Included in Our Leak Repairs

Every chimney leak repair includes a complete system evaluation, not just a quick fix of the obvious problem. We address flashing issues, crown damage, mortar deterioration, and any other water entry points we discover.

In Somerville, we see a lot of chimney problems caused by the area’s older housing stock and harsh winter conditions. Many homes built in the early 1900s have original mortar that’s finally giving way after decades of freeze-thaw cycles. Others have had amateur repairs over the years that actually made the water intrusion worse.

We fix these problems using modern materials and techniques that are designed specifically for Massachusetts weather. Our repairs come with warranties because we stand behind our work, and we use only licensed, insured professionals who understand local building codes.

You’ll also get a clear explanation of what caused your leak and practical advice on preventing future problems.

How much does chimney leak repair cost in Somerville, MA?

Most chimney leak repairs in Somerville cost between $150 and $1,200, depending on what’s causing the leak and how extensive the damage is. Simple flashing repairs or crown sealing typically run $200-$500, while more complex issues involving structural damage can cost $1,000-$3,000. The key is catching problems early. A $300 flashing repair today can prevent thousands in water damage repairs later. We always provide upfront pricing before starting any work, so you’ll know exactly what you’re paying for. Keep in mind that ignoring a chimney leak usually makes it much more expensive to fix. Water damage spreads, and what starts as a minor repair can quickly become a major reconstruction project.

What causes chimney leaks in Somerville homes?

The most common causes we see in Somerville are damaged flashing, cracked chimney crowns, and deteriorated mortar joints. Massachusetts winters are particularly hard on chimneys because water gets into small cracks and then expands when it freezes, making the cracks bigger. Flashing problems are especially common in older homes where the original installation wasn’t done properly or has simply worn out over time. The flashing is the metal barrier that seals the gap between your chimney and roof, and when it fails, water pours right into your house. Crown damage happens when the concrete cap at the top of your chimney develops cracks. Once water gets in, it can cause serious structural problems throughout the entire chimney system. We also see a lot of mortar joint failures in Somerville’s older brick chimneys, where decades of weather exposure have finally taken their toll.

How do I know if my chimney leak is serious?

Any chimney leak is potentially serious, but there are some warning signs that mean you need immediate attention. Water stains on walls or ceilings near your chimney, white chalky deposits on the outside bricks, or a musty smell in rooms adjacent to the chimney all indicate ongoing water intrusion. If you see actual water dripping or pooling inside your fireplace, that’s a clear sign of a significant leak that’s probably been going on for a while. Rust on your damper or firebox, peeling paint near the chimney, or wallpaper coming loose on chimney walls also indicate moisture problems. The tricky thing about chimney leaks is that by the time you see obvious signs inside your house, there’s usually already extensive hidden damage. Water can travel along beams and through wall cavities before you actually see it, which is why professional inspection is so important when you suspect a leak.

Can I use my fireplace if my chimney is leaking?

You shouldn’t use your fireplace if you know your chimney is leaking. Water intrusion can damage the flue liner, which is what protects your house from dangerous gases like carbon monoxide. A compromised liner can allow these toxic fumes to leak into your home instead of being safely vented outside. Water damage can also affect the structural integrity of your chimney, creating fire hazards or even the risk of collapse. Plus, using your fireplace while there’s active water intrusion will likely make the damage worse and more expensive to repair. The safest approach is to have the leak properly diagnosed and repaired before using your fireplace again. Most chimney leak repairs can be completed quickly, especially if you catch the problem early, so you won’t be without your fireplace for long.

How long do chimney leak repairs last in Massachusetts weather?

When done properly with quality materials, chimney leak repairs should last 15-20 years or more, even in Massachusetts weather. The key is using materials specifically designed for freeze-thaw cycles and making sure the underlying cause of the leak is completely addressed, not just the symptoms. We use high-grade sealants, properly installed flashing, and mortar mixes that are formulated for New England conditions. Cheap materials or amateur repairs often fail within a few years because they can’t handle the expansion and contraction that happens during our winter-to-summer temperature swings. Regular maintenance also extends the life of repairs. Annual chimney inspections can catch small problems before they become big ones, and simple preventive measures like keeping your chimney cap in good condition can prevent most water intrusion issues. We provide specific maintenance recommendations based on your chimney’s age, condition, and exposure to help you get the maximum life from our repairs.

Should I repair or rebuild my leaking chimney?

This depends on the extent of the water damage and the overall condition of your chimney. If the leak is caught early and the structural components are still sound, repair is usually the most cost-effective option. Simple flashing replacement or crown sealing can solve most leak problems for a fraction of the cost of rebuilding. However, if water has been getting in for years and has caused extensive mortar deterioration, brick spalling, or structural damage, rebuilding might actually be more economical in the long run. A partial rebuild of just the damaged sections typically costs $2,000-$4,000, while a complete rebuild runs $8,000-$15,000. We’ll give you an honest assessment of your chimney’s condition and explain all your options with realistic cost estimates. Sometimes what looks like a major problem can be fixed with targeted repairs, and other times what seems like a small leak indicates much more serious underlying damage that requires extensive work.
