Our Chimney Services in Long Island

Chimney Installation in Long Island

A chimney is your home’s lung. We make sure it breathes for life.


If you’re building or remodeling, don’t gamble with cookie-cutter installs. Chimneys on Long Island face salt air, wind load, freeze-thaw shifts, and your installer needs to account for all of it. Our certified team builds masonry and prefab chimneys that match your roof pitch, manage vapor, and seal like a vault.

Our Chimney Installation Process

Foundation-First Prep

Before anything goes up, our chimney specialists go under to inspect your roof slope, framing support, and moisture zones. Because no two homes breathe the same, we calculate structural load and placement to ensure stability that lasts decades.

Custom Drafting and Ventilation Sizing

Drafting isn’t guesswork. It’s precision airflow design from hearth to flue. Our installation team matches flue diameter, chimney height, and damper mechanics. Allowing smoke to rise naturally, fires to burn cleanly, and your living room to stay smoke-free.

Flashing and Counter Flashing

This is where 90% of chimney leaks begin and where our team gets surgical. Instead of tucking flashing under shingles, we interlock high-gauge aluminum into the underlayment and the brick mortar joints. Then we double-seal with counter flashing that drives water away. It’s a tight seal, Long Island storms can’t mess with.

Crown Pour and Weather Sealing

The chimney crown is your shield. Our masons hand-tool a sloped, fiber-reinforced concrete crown for perfect drainage. Yes, no puddles or pooling. We top it with a breathable water sealer that flexes with freeze-thaw cycles, a must in Long Island’s weather.

Cap and Spark Arrestor Fitment

Your fire stays in. Embers stay out. The finishing touch? A hurricane-rated, stainless steel cap with integrated spark arrestor. Our chimney installers torque it to code and anchor it for wind uplift because Long Island doesn’t play nice with loose metal.

Your fire stays where it belongs. So does your peace of mind. Call (631) 644-9411.

Chimney Repair in Long Island

It started as a hairline crack. Now it’s leaking water, smoke, and stress.


If your chimney’s failing, you unfortunately don’t always see it until it’s too late. Whether you notice stains on the ceiling, a musty smell, or your fireplace that doesn’t draw like it used to. These are signs, and we’ve seen them all.

Roof Problems That Start at the Chimney and How We Fix Them

  • Cracked Mortar Joints

    Crumbling lines between bricks? That’s decayed mortar. Our masons grind it out and repoint with a perfect match to restore strength without changing the look.

  • Leaking or Missing Flashing

    It is the #1 source of many chimney leaks. Our team installs full systems: base, step, and counter flashing sealed into both the roof and chimney, so water has nowhere to slip through.

  • Spalling Bricks

    Flaking, cracking bricks usually mean trapped moisture. Damaged units get replaced, then sealed with breathable protection that stands up to Long Island’s brutal winters.

  • Crown Cracks & Cap Gaps

    Pooling water on the crown? That’s a slope or seal failure. We resurface or recast with fiber-reinforced concrete and coat it to keep freeze damage out for good.

  • Smoke Backups

    If smoke’s coming in, not out, then there’s a draw issue. Chimney experts check for height, flue size, and blockages, then reline or resize to fix the flow.

Stop living with “almost safe.” Call Precision at (631) 644-9411 and make your chimney trustworthy again.

CLIENT SATISFACTION

HEAR FROM SATISFIED CLIENTS

Calvin just left and I cannot write this review fast enough! If I could give 10 stars, I would! He transformed my old, dilapidated shed into one that literally looks and feels brand new. He went above and beyond with his work. He also repaired the siding on my house that keeps blowing off whenever the wind gets a little gusty. He was extremely responsive, communicative, knowledgeable, open, and friendly. I think it's hard to find quality service people with integrity, but this guy's it!! Call him! You deserve his work and he deserves your business.

I had an incredible experience with this construction company! They did the siding on my house and truly went above and beyond. Every single person on the team was respectful, helpful, and extremely knowledgeable. They showed up on time every day, worked efficiently, and completed the job way faster than I expected—without ever cutting corners. Their attention to detail was spot on, and they left the place spotless when they were done. I couldn’t be happier with how everything turned out. Highly recommend! I have a brand new home 🥰

Calvin and his team did our roof today. They did an incredible job! They took pride in their workmanship and were meticulous in their clean up. I must've asked Calvin 100 questions throughout the day and each time he was patient, honest, and knowledgeable.Will 100% use in the future for any home renovation needs. Google wouldn't let me upload videos, but here are some pics as they were finishing up.

I cannot say enough about Calvin. He was kind, professional and very responsive. He also gave the most competitive pricing. I had full vinyl siding replaced all around the house. We went over color options and came out to me a second time to go over the job in detail. Did the entire job in less than two days. First two pictures are of the old siding.
