When your chimney’s mortar joints fail, water finds its way in. That’s when small problems turn into expensive headaches—cracked bricks, interior water damage, even structural collapse.
Professional chimney repointing stops this cycle cold. We remove the deteriorated mortar and replace it with properly matched materials that seal out moisture for decades. Your chimney becomes weatherproof again, your home stays dry, and you avoid the thousands of dollars that major repairs can cost.
The difference is immediate and lasting. No more worrying about water stains on your walls or wondering if that next storm will cause serious damage.
SkyLuxe Construction has been serving Suffolk County families for years, and we understand what Long Island weather does to chimneys. The freeze-thaw cycles, coastal moisture, and seasonal storms that make Stony Brook beautiful also take a toll on masonry.
We’re not just another contractor. We’re your neighbors who know that when mortar starts cracking around here, you need it fixed right the first time. Our family-run business brings that personal touch to every job, whether it’s a small repointing project or comprehensive chimney restoration.
Stony Brook homeowners trust us because we show up when we say we will, we explain what we’re doing and why, and we stand behind our work with real guarantees.
First, we inspect your entire chimney to assess the extent of mortar deterioration and identify any underlying issues that need attention. You’ll know exactly what needs fixing and why before we start any work.
Next, we carefully remove the damaged mortar to the proper depth—typically about half an inch—without disturbing the surrounding bricks. This step requires precision because removing too much or too little affects the repair’s longevity.
Then we mix new mortar that matches your existing material in both strength and appearance. We use Type N mortar for most Long Island chimneys because it provides the right balance of flexibility and durability for our climate. The new mortar is applied in layers, properly tooled, and allowed to cure slowly for maximum strength.
Finally, we clean up completely and walk you through the finished work. You’ll see exactly what we’ve repaired and understand how to maintain your chimney going forward.

Our chimney repointing service covers everything needed to restore your masonry properly. We start with a thorough inspection to identify all problem areas, not just the obvious ones you can see from the ground.
The work includes complete removal of deteriorated mortar, proper surface preparation, and installation of new mortar mixed specifically for your chimney’s age and construction. We also seal any minor cracks in the bricks themselves and apply weatherproofing where appropriate.
In Stony Brook, we see a lot of chimneys that were built in the 1960s and 70s when the area was developing rapidly. These homes often have specific mortar types that need to be matched exactly for the repair to last. We keep detailed records of what works best for different construction eras in our area.
You’ll also get a clear timeline—most repointing jobs take one to two days depending on the chimney’s size and condition—and a detailed explanation of what to expect as the mortar cures over the following weeks.
Chimney repointing in Stony Brook typically costs between $800 and $2,500, depending on your chimney’s size, height, and the extent of mortar damage. Most homeowners in our area spend around $1,200 to $1,800 for a complete repointing job.
The cost varies because every chimney is different. A small, single-story ranch chimney with minor mortar issues costs less than a tall, two-story colonial chimney with extensive deterioration. Access also matters—chimneys that require scaffolding or special equipment cost more than those easily reached from a standard ladder.
We always provide a detailed written estimate that breaks down exactly what you’re paying for, so there are no surprises. The investment is worth it when you consider that proper repointing can extend your chimney’s life by 20-30 years and prevent water damage that could cost thousands to repair.
Repointing completely removes old, deteriorated mortar and replaces it with new material—it’s the comprehensive repair most chimneys need. Tuckpointing fills minor cracks and gaps in existing mortar that’s still structurally sound, often with contrasting colors for a decorative appearance.
For most Stony Brook chimneys, repointing is the right choice because our climate is tough on mortar. The freeze-thaw cycles we get here cause mortar to crack and crumble, not just develop surface issues. When mortar fails in Long Island’s weather, it usually needs complete replacement, not just patching.
Tuckpointing might work for newer chimneys with minor cosmetic issues, but if you’re seeing chunks of mortar falling out or water problems, repointing is what will actually solve the problem long-term. We’ll assess your specific situation and recommend the approach that makes the most sense for your chimney and budget.
Most chimney repointing projects take one to two days to complete, though larger or more complex jobs can take up to three days. The timeline depends on your chimney’s size, the extent of damage, and weather conditions during the work.
Day one typically involves setting up equipment, removing old mortar, and beginning the repointing process. Day two focuses on completing the mortar installation, tooling the joints for proper water shedding, and cleanup. If your chimney is particularly tall or has extensive damage, we might need an additional day to ensure everything is done properly.
Weather plays a role too—we can’t do quality mortar work in freezing temperatures or during rain, so winter projects sometimes take longer due to scheduling around suitable conditions. We’ll give you a realistic timeline upfront and keep you updated if anything changes during the work.
Look for mortar that’s cracking, crumbling, or falling out of the joints between bricks. If you can easily scrape mortar out with a key or coin, or if you see white powdery residue on the bricks, your chimney likely needs repointing.
Water problems are another clear sign—if you’re getting leaks around your chimney during rainstorms, or if you see water stains on walls or ceilings near the chimney, deteriorated mortar is often the culprit. In Stony Brook’s climate, mortar typically lasts 20-30 years before needing replacement, so if your chimney is approaching that age, it’s worth having it inspected.
You might also notice bricks that seem loose or shifting, or joints where you can see deeper into the chimney than you should. Don’t wait until chunks of mortar are falling into your yard—early repointing is much less expensive than waiting until the damage spreads to the bricks themselves.
We typically use Type N mortar for most chimney repointing in Stony Brook because it provides the right balance of strength and flexibility for Long Island’s climate. Type N mortar consists of one part cement, one part lime, and six parts sand, making it durable enough to last decades while flexible enough to handle our freeze-thaw cycles.
The key is matching the mortar to what was originally used in your chimney. Using mortar that’s too hard can actually crack softer, older bricks, while mortar that’s too soft won’t provide adequate protection. We analyze your existing mortar and choose the appropriate replacement that will bond properly with your specific bricks.
We also color-match the new mortar to your existing chimney so the repair looks natural, not like an obvious patch job. The mortar is mixed on-site in small batches to ensure consistency and proper curing, which is crucial for a repair that will last 20-30 years.
Chimney repointing requires specialized skills, proper tools, and safety equipment that most homeowners don’t have. Working at height, handling masonry tools, and mixing mortar to the correct consistency are all skills that take experience to do safely and effectively.
The bigger issue is that improper repointing can actually make problems worse. Using the wrong mortar type, removing too much or too little old mortar, or not properly curing the new mortar can lead to premature failure and more expensive repairs later. We’ve seen many DIY attempts that ended up costing homeowners more than hiring professionals would have originally.
Professional repointing also comes with warranties and insurance coverage that protect you if something goes wrong. When you consider the cost of scaffolding rental, specialized tools, materials, and the time involved, professional service often costs less than doing it yourself—and you get results that will last decades instead of just a few years.
