Let me introduce myself and tell you about us. I’m Mike, the founder and owner of MCP Chimney and Masonry. MCP is a company I started in 1994 with only an old pickup, three hundred dollars, and a mission to treat all of my customers like family. Today, each MCP employee is trained to provide the highest quality chimney work. We want to be more than just your average contractor, we want to be the personal chimney and masonry company that you can trust and rely on for a lifetime. As you can imagine, trustworthiness in a chimney company is paramount. Customers cannot easily see chimney work that is recommended. MCP treats our customers the way we like to be treated as customers. I am so grateful that our customers’ trust in us over the years has spurred our growth despite minimal advertising. These word of mouth recommendations of our fiercely loyal customer base has pushed MCP from a single employee with a single truck to twenty-five year-round employees working in fully staffed offices. We hope you will give us a chance to be your trusted chimney company. We will work hard to keep you happy.
"On March 12th and 13th 2020 MCP Chimney installers were replaced an existing knee wall in my back yard. I discovered my AC was not working in May 2020 and contacted my Home Warranty company who sent a technician on June 2, 2020. The HVAC tech was unable to determine an issue with my outdoor AC Condenser and reported to me it would be $680 for a line test and approximately $1500 to replace the line if that was even the issue. My Home Warranty would of course not cover this charge. I decided to replace the system after spending an excess of $1200 on refurbishing the condenser in April of 2019. In June BGE Home came to my home to replace my system where the installer reported to me that the" intake line was the worse pinched line he had ever seen." I could not for the life of me understand how this happened and only could assume it was related to replacing the retaining wall but had no evidence. I was archiving my pictures in my cell phone November 23,2020 and found the pictures that I was taking as the work was being performed on my knee wall. When blowing the area up on my phone it was obvious that the intake line had been re-caulked between March 12th and 13th. I contacted the owner Michael Pentifallo on November 30th where he contacted me immediately, he said he would speak to his installer of 12 years and get back to me. Michael Pentifallo did contact me again on 12/1/20 were he acknowledged that he spoke to the installer Jamie, and of course he said he knew nothing about it. He also said he went to my property on November 30th 2020 without my consent or knowledge, chastised me for not reporting this sooner, acknowledged that the caulk did appear different in the photos, but it was not them it was not the way the conducted business & he would see me in small claims court sense I reported it so late and had no evidence for him to review on site. How would I have evidence if it was discovered as the unit was being replaced? If his installer had been honest this matter would have been quickly resolved."

Yes, a chimney cap is essential for keeping birds, squirrels, rain, and debris out of the flue. By stopping stray embers and blocking downdrafts, a chimney cap helps your fireplace run safely and efficiently. The cap also protects the chimney’s inner walls from moisture damage, saving you from costly repairs down the road.
Most chimney caps last anywhere from three to 25 years. Galvanized steel sits at the low end, while stainless steel, aluminum, and especially copper can exceed the 25-year mark. Annual inspections, quick repairs, and routine chimney cleanings all help the cap reach its full lifespan and keep the flue protected.
A good rule of thumb is to set the cap at least eight inches above the top of the flue. That clearance keeps the draft strong, lets smoke exit freely, and prevents back-puffing into your living room. Extra height also adds a little more protection from wind-driven rain and snow without hurting airflow.
The crown is the solid concrete or mortar slab that sits on top of the chimney stack and sheds water away from the masonry. The cap, mounted above the flue, adds the final layer of defense by blocking rain, animals, and embers while still letting smoke out. Working together, the crown guards the structure and the cap safeguards the flue.
