What Suffolk County homeowners say.

They told us our chimney didn't need anything done. Just a sweep and a new cap. No upsell. Rosa in the office scheduled us fast and called the night before. Easy five stars.

Kevin P.
Commack, NY · Google · 2025-12-10

Annual inspection and sweep for our wood-burning fireplace in Smithtown. Chris was on time, wore booties inside, cleaned up completely. Explained creosote stages in a way I actually understood. We'll use them every fall.

Sarah T.
Smithtown, NY · BBB · 2025-11-30

Called for a chimney cap replacement after a storm took ours off. They had one installed within 48 hours. Quality stainless with a lifetime warranty. Fair pricing and honest work.

David K.
Hauppauge, NY · Google · 2025-11-08

Tuckpointing on our old brick chimney — they were the only company that actually knew what tuckpointing IS versus just repointing. Paul is a real mason, not a guy with a trowel. The work is beautiful.

Lisa B.
Huntington, NY · Angi · 2025-10-21

Waterproofing service on our brick chimney and the crown coat — Frank explained why our chimney was leaking and exactly what to do. Six months later, no more stains on the ceiling. Problem solved.
