Chimney Repair & Rebuilding Services
We fix and rebuild chimneys to keep your home safe from leaks, drafts, and dangerous carbon monoxide hazards.
Common Chimney Problems We Fix
Chimneys take a beating from weather, temperature changes, and years of use. Water is the main culprit behind most chimney damage. When water gets into cracks in the masonry or through damaged flashing, it causes all sorts of problems. In winter, that water freezes and expands, making cracks bigger. Over time, this cycle breaks down the mortar and can even crack the bricks themselves. You might notice water stains on your ceiling near the chimney or smell dampness in your home.
Another common issue is deteriorating chimney crowns. The crown is the concrete cap at the top of your chimney that keeps water out. When it cracks, water runs down inside the chimney and damages the flue liner, mortar, and interior walls. We also see a lot of problems with damaged flashing where the chimney meets your roof. This metal seal needs to be watertight, and when it fails, water leaks into your home. At VJM Vallejo Masonry, we inspect every part of your chimney to find all the problems before we start repairs.
Warning Signs Your Chimney Needs Attention
- White staining or efflorescence on exterior chimney bricks
- Crumbling mortar joints between bricks or stones
- Damaged or missing chimney crown at the top
- Rust stains on the firebox or damper
- Pieces of brick or tile falling into your fireplace
- Visible cracks in the chimney structure
- Chimney leaning or tilting away from the house
- Water leaks in your home near the chimney
Do not ignore these signs. A damaged chimney is not just an eyesore. It creates serious safety risks including fire hazards and carbon monoxide leaks. Early repairs cost far less than waiting until the chimney needs complete rebuilding.
Should You Repair or Rebuild Your Chimney?
This is the first question we answer during your consultation. The decision depends on how much damage exists and where it is located. If the damage is limited to the crown, flashing, or a few bricks, repairs are usually the best option. These fixes restore function and prevent further damage without the expense of a complete rebuild. We can replace sections of damaged masonry, install new flashing, rebuild the crown, and reline the flue if needed.
When Rebuilding Makes Sense
Sometimes a chimney is too far gone for repairs to be practical or safe. If your chimney is leaning more than a few inches, has major structural cracks throughout, or shows extensive deterioration in multiple areas, rebuilding is the better choice. A leaning chimney indicates foundation problems that need to be corrected. We rebuild from the roofline up in most cases, which costs less than tearing down to the foundation. However, if there are foundation issues, we address those first to prevent the new chimney from failing.
Our rebuilds use modern materials and techniques that exceed building code requirements. We install proper flue liners, build solid crowns with drip edges, and use high-quality mortar that resists water penetration. The result is a chimney that looks great and will last for decades. We also handle all the necessary permits and inspections, so you do not have to worry about compliance issues.
The Inspection Process
Every chimney project starts with a thorough inspection. We climb on your roof to examine the crown, flashing, and cap. We check the exterior masonry for cracks, spalling, and deteriorated mortar. Inside, we inspect the flue liner, damper, and firebox. We look for structural movement, water damage, and safety issues. You get a detailed written assessment that explains what we found and what needs to be done. This gives you the information to make an informed decision about repairs versus rebuilding. Our brick repair services can often save chimneys that seem too damaged to fix.
Safety First: Code Compliance and Best Practices
Chimney work is not something you want to trust to just anyone. Poor workmanship can create serious hazards including house fires and carbon monoxide poisoning. We follow all local building codes and National Fire Protection Association guidelines for chimney construction. This means using proper clearances from combustible materials, installing appropriate flue liners, and building solid structures that can withstand decades of use.
Carbon monoxide is especially dangerous because you cannot see or smell it. A damaged flue liner or cracked chimney can allow these deadly gases to leak into your home. We make sure your chimney vents properly and has no cracks or gaps that could let gases escape. Regular inspections and maintenance keep your chimney safe. We recommend having your chimney inspected at least once a year, especially if you use your fireplace regularly.
Premium Materials for Lasting Results
We use the best materials available for chimney work. Flue liners are typically stainless steel or clay tile, depending on your heating system and local codes. Crowns are built with reinforced concrete and proper slopes for water runoff. Flashing is heavy-gauge copper or lead-coated copper that will not rust or deteriorate. For the masonry itself, we use bricks and mortar that match your existing chimney and can withstand temperature extremes. Quality materials cost more upfront but save money over time by lasting longer and requiring less maintenance. Our work on tuckpointing and repointing ensures your chimney mortar stays strong for years.
We also make sure your chimney has proper ventilation and a cap to keep out rain, animals, and debris. A good chimney cap pays for itself by preventing water damage and blockages that cause dangerous backdrafts.
