"Nasir did a great job! The service was very easy and quick to schedule and they communicated with us throughout. The fireplace had never been cleaned before and is now spotless with no residual smokey smell. Nasir was very friendly and even fixed and issue with our flume that was causing it not to open all the way. We are very pleased with the service!"

"Good job but overcharged for putting a standard chimney cap. They also gave me a quote to get my chimney cleaned for $500. I got my entire house deep cleaned for $150 and they expect me to pay $500 for getting the chimney cleaned."

"We recently remodeled our bathroom with McCormick, and it was a fantastic experience. Khaled was informative, patient, and genuinely helpful, guiding us through choices for a perfect design. The team’s professionalism showed in their punctuality and quality. Every aspect was done with care, from tile placement to lighting. The transformation is truly impressive; the bathroom now feels open and luxurious. We’re beyond pleased with the result and look forward to more projects with them."

Fireplaces questions, answered by experts

Regular inspections, using dry wood, and installing chimney caps help maintain efficiency and safety.

The damper, located just above the firebox, can open or close the chimney flue. The damper should remain closed unless there’s a fire burning in the fireplace. Closing the damper prevents energy loss through the chimney and cold air from seeping into the home during the winter. Opening the damper helps maintain airflow when there is a fire and prevents smoke and gases from venting into the house.

A chimney cap costs about $300 on average to install, with prices ranging from $75 to $1,000. The final cost depends on several factors, including the professional you hire, the accessibility of your chimney, the cap's material and size, whether any repairs are needed, and if it requires custom fabrication. Chimney caps are usually made from galvanized steel, stainless steel, or copper. Copper caps are the most expensive, followed by stainless steel and then galvanized steel. Excluding labor, average material costs are around $100 for galvanized steel, $250 for stainless steel, and $600 for copper. You may also face additional costs, such as hiring a chimney sweep to clean the chimney before the cap is installed.

The time it takes for creosote to build up in a chimney can vary depending on how often you use your fireplace and the wood you burn. Creosote can start accumulating after just a few fires, especially if you burn unseasoned wood or allow fires to smolder. Regularly using the fireplace without proper maintenance can lead to significant creosote buildup within a few months. To prevent hazardous buildup, have your chimney inspected and cleaned at least once a year.

If your gas fireplace is vented through a chimney, a chimney cap is highly recommended. While not all gas fireplaces require a traditional chimney, for those that use one, a cap provides several key benefits. It prevents rain, debris, and animals from entering the chimney, which can cause blockages or damage. A cap also helps prevent downdrafts that could push harmful gases like carbon monoxide back into your home. When installing a cap, ensure it is appropriate for a gas fireplace and does not restrict proper ventilation.
