Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in Valley Stream, NY
Alcott Chimney Sweep handles chimney cleaning, inspection, and gas fireplace repair for Valley Stream homeowners. The homes here, mostly built between the 1920s and 1960s, still carry the original masonry chimneys many cities have already torn down. That means the work we do in Valley Stream leans heavily on relining, mortar repair, and preparing older flues for gas appliances they were never designed for. Call (518) 719-4643 for a free estimate, and you’ll get a written price before any work starts.
Why Valley Stream Homes Are Different
Valley Stream’s housing stock is dense with pre-war and mid-century single-family homes: brick and stucco exteriors, traditional masonry chimneys, and clay tile liners that are now 60 to 100 years old. Many of those liners are cracked, spalled, or missing entirely. When oil-to-gas conversions happened across Nassau County, a lot of homeowners discovered their original flues could not pass inspection without a stainless steel liner. We see this weekly in Valley Stream, and it’s exactly the kind of job that needs a camera inspection first so you can see the condition with your own eyes before anyone quotes a liner.
Coastal humidity and freeze-thaw cycles work against these older chimneys year-round. Moisture gets into hairline cracks, freezes, expands, and widens the damage. By spring, joints that looked fine in November are crumbling. This is why annual chimney inspections matter more here than in drier inland towns. Valley Stream’s fire codes and insurance requirements are strict, and a failed inspection can hold up a home sale or a renovation permit. We know what inspectors in this area look for because we’re called in to fix it regularly.

Our Main Valley Stream Services
These are the three services Valley Stream homeowners call us about most. Each one has its own dedicated page with pricing, timelines, and what to expect.
Chimney Sweep in Valley Stream
A sweep in Valley Stream means more than brushing out soot. Older flues in this area carry creosote, the tar-like buildup that causes chimney fires, and often debris from deteriorating clay tile liners. We remove the buildup, check for blockages, and let you know if we see liner damage that needs attention. Coastal moisture makes creosote stick differently here than in dryer climates, so we pay extra attention to glazing in the flue. Learn more on our Chimney Sweep in Valley Stream page.
Chimney Inspection in Valley Stream
An inspection in Valley Stream should include a camera run every time, because the flues we’re looking at are old enough to hide cracks the naked eye can’t reach. We document everything with photos and show you exactly what we find. If you’re buying a 1940s colonial or preparing a rental for a new tenant, a documented inspection is what Nassau County permits and insurance companies want to see. Details are on the Chimney Inspection in Valley Stream page.
Gas Fireplace Repair in Valley Stream
Many Valley Stream homes converted from oil to gas decades ago, and the fireplaces that came with that conversion are now hitting the end of their service life. We repair thermocouples, valves, pilot assemblies, and ignition systems, and we work with the trade brands that hold up in this coastal climate. If your gas fireplace won’t stay lit or smells off when it runs, shut it down and call us. See the Gas Fireplace Repair in Valley Stream page for what we fix and how quickly.

FAQs About Chimney Company in Valley Stream
We schedule most Valley Stream visits within a few business days. If you smell smoke or suspect a chimney fire, call immediately and we’ll prioritize it. We coordinate dispatch from our New York City office, and a live person answers the phone around the clock.
Most routine sweeps and inspections don’t require a permit. Structural work like a full rebuild or liner replacement may, depending on the scope. Nassau County has specific requirements, and we’ll tell you before any work starts whether a permit applies to your job.
That’s what the inspection is for. We run a camera through the flue, show you the photos, and explain what’s urgent, what can wait, and what’s cosmetic. Nothing gets recommended without visual evidence you can see yourself. Call (518) 719-4643 for a free estimate.

What Valley Stream Customers Say
"Annual inspection and sweep. He used a camera to check the liner and found a cracked tile I had no idea about. Gave me a written estimate and did not push."
- Janet W."The report he wrote up had pictures and clear notes for the insurance. That alone was worth it."
- Garrett I."Good chimney cleaning. They found a small gap in the mortar and quoted the repair, which was a bit more than I wanted to spend. Did the sweep and left the repair for later without any pressure."
