If you are looking for a good price and professional service then look no further. Paulie, the service technician is a rock star when it comes to chimneys, he sucessfully restored my 100 year old fireplace 2 years ago and did it for a super affordable price explaining everything to me along the way. I can now enjoy my fireplace like I always wanted. Highly recommended.

Had a great experience with them! They called me up reminding me that I was overdue for a chimney cleaning, scheduled me the next day, arrived timely and were very polite and now I'm all set.

Warning Signs You Need to Schedule an Appointment with a Lake Grove, NY Chimney Repair Specialist

Signs You Need to Contact a Lake Grove, NY Chimney Repair Professional

A fireplace is a wonderful feature of your Suffolk County home. It provides reliable warmth, creates ambiance, and adds to the aesthetic appeal of your home’s interior. The chimney is a vital component of your fireplace, as it exhausts excess heat, smoke, and soot out of your house, and feeds fires with the oxygen they need to burn. Because it’s such an integral part of the fireplace, you know that yearly chimney cleaning and inspections are important; however, between routine chimney maintenance services, issues can arise that require immediate repair.

A damaged chimney is a serious fire hazard. To protect your Suffolk County home and your family, it’s important to be aware of the signs that indicate you’re in need of chimney repair services. Pay attention to the structure and if you notice any of the following, you’re going to want to schedule an appointment with a reputable Lake Grove, NY chimney sweep that specializes in repairs.

White Staining

Do you see white stains on your chimney? That’s efflorescence, and while the spots are fairly easy to remove, cleaning won’t resolve the issue that caused the residue buildup. Those white stains are a clear indication of a moisture problem. Efflorescence is a deposit of salt that forms when moisture is present in masonry materials, such as brick, concrete, or stone. As the moisture dries, the salt rises to the surface and leaves a white residue behind. If the moisture problem that’s causing the efflorescence is left unchecked, premature deterioration of the structure is likely to occur, on top of other moisture-related issues. At the first sign of white spots on your Suffolk County chimney, contact a chimney repair specialist.

Damaged Mortar Joints

Are the mortar joints between our chimney’s masonry damaged? If so, you’re going to want to call in a Lake Grove, NY chimney sweep that specializes in masonry repairs. Mortar is the glue that holds your chimney together. If it deteriorates, not only will the structure be weakened, but the masonry will be exposed to moisture, which will accelerate deterioration and cause a variety of other problems. Ultimately, the entire structure could fall. Keep an eye on your chimney’s mortar joints. If they’re cracking, crumbling, or pieces are missing, schedule an appointment with a Suffolk County chimney repair company.


Are you having a hard time opening and closing your damper? Is your firebox covered with discolored spots or specks? If so, rust is likely to blame, and rust is a clear indication of a moisture problem. Water could be seeping through cracks in the mortar joints, through the bricks, or bypassing the chimney cap. No matter the cause, rust is just one of the effects that moisture can have on a chimney; it can also crack the flue tiles, damage the mortar joints, and ultimately, it could weaken the entire structure. If you suspect you have rust in your fireplace, call a reputable Suffolk County chimney repair company.

Crumbing Flue Tile

Have you seen piles of chimney tiles collecting in the bottom of your fireplace? If so, chances are your flue is damaged. This issue is known as shaling, and it can occur for a number of reasons, including moisture damage, poor installation, or simply age. Whatever the cause, it’s imperative to call a Lake Grove, NY chimney sweep that offers repair services as soon as possible. A flue is a vital component of a chimney. If it’s damaged, the structure can become a serious fire hazard.

Some information about Lake Grove

Lake Grove is a village in the town of Brookhaven, Suffolk County, New York, United States. The population was 11,163 at the 2010 census. The village is officially known as the Incorporated Village of Lake Grove.

The area of Lake Grove was settled in the early 18th century along Middle Country Road, which was then part of the Old Kings Highway, originally a Native American footpath. The community’s first church building, built in 1818, was the First Congregational Church of New Village. Placed on the National Register of Historic Places in 2002, the building has been preserved and is depicted on the village seal. In 1870, Lake Grove established its first post office, which carried the mail to and from Lakeland station (discontinued in 1883) by horse and wagon. The area was variously called Lakeland, Lakeville, New Village, Ronkonkoma or West Middle Island until it settled on the name Lake Grove in mid-19th century, after the groves of trees near Lake Ronkonkoma.

During the early 20th century Lake Ronkonkoma became a popular area for recreation, which prompted many small summer houses built on private roads of Lake Grove. In 1921, a new post office was erected in the eastern part of the area and given the name of . The next significant housing development built in Lake Grove was called Brook Lawn and was located on Stony Brook Road, which later grew into Stony Brook. More developments followed and the population of Lake Grove increased rapidly. In 1954, newly built Nesconset Highway created a major commercial crossroad in Lake Grove, which prompted the construction of the Smith Haven Mall in 1968, which made the local residents become concerned about the impact of new businesses and increased traffic in their community. In order to gain local control of the zoning and planning, Lake Grove was incorporated by a vote of 552 to 332 on September 9, 1968.
