We received a call to fix a leaky chimney in Potomac, Maryland. The customer informed us that they hired another company for chimney repairs but their chimney still leaks. As a result, he thought it was a roofing issue. A roofer came out to evaluate the situation and assured the customer that it was the chimney. The customer was pretty upset with the other company. The customer started looking for a chimney repair company in Montgomery County that had a reputation for qualtiy work. They decided to call us, All Pro Chimney Service. After performing a chimney inspection we discovered that the only thing the other company did right was a chimney sweep. There were still serious problems with the chimney cover and chimney cap.
(*The chase cover is the big rectangular piece on top.)
Here we have a picture of the chimney. The chase cover has been replaced with a stainless steel chase cover and the cap replaced as well with an aftermarket cap.
If you look closely you can see the neighbors chase cover is rusted and will need to have theirs replaced as well. A rusted chase cover will not only cause leaks but also leave unsightly rust stains on the chimney.
So with the chase cover having been replaced what else could the problem be? Well there are two issues’ here that were causing this chimney to leak.
First, the cap that was installed is not the correct cap for this fireplace/chimney. This fireplace uses a double wall ventilated chimney. This cap that was installed is designed for solid packed chimney which means that the cap does not have the air space build in to it to allow the chimney to ventilate properly and could cause it to overheat. The other issue with the cap is that it doesn’t completely cover the pipe so when it rains really hard and on windy days the rain can get in.
The second issue is that the storm collar is too small for the collar of the chase cover and is allowing rain to come right in. This storm collar looks to be the original one and was reused. The problem is that when they measured the chase cover they made the collar of the opening bigger than what was there initially so they should have replaced the storm collar with one that has a larger span to insure that water cannot leak in.
Here is a picture of the new cap and storm collar. This cap was made by the manufacturer for this fireplace/chimney system. It has the air space underneath the lid of the cap to allow chimney to ventilate properly. We installed a new stainless steel storm collar that completely covers the collar of the chase cover.
After picture- The chimney repair in Potomac, MD is now complete. We installed 2 of these at this house.
The sad part of this story is that this customer had to pay twice to get their chimney repaired. It is always better to hire a dependable professional chimney repair company the first time. All Pro Chimney Service is the best choice for chimney repair.

There is nothing quite as cozy and comfortable to snuggle up to on a cold winter’s night as a roaring fire in the fireplace. There is also nothing more disastrous than lighting that fire only to realize (too late) that your chimney is not in good working order. Getting a chimney sweep is the best way to prevent this problem. As a result many smart home owners in Silver Spring and all over the state of Maryland hire chimney repair companies for annual chimney sweeps.
That leads to an important question. What exactly is a chimney sweep?
The National Fire Protection Association Standard 211 (NFPA 211) recommends that chimneys, fireplaces, and vents should be inspected at least once a year so that the chimneys, fireplaces, and vents are sound, free from deposits, and that all clearances are met. That is one of the many reasons homeowners should get a chimney sweep every year. With such an important job at hand, it is vital that chimney sweeps only be performed by a certified expert that knows exactly what to look for and how to sweep that chimney in the safest, easiest and most efficient way possible. Hiring a professional chimney sweep is the best way to ensure that your fireplace and chimney are in tip-top shape and ready for the season ahead.
What a Chimney Sweep Does
A professional chimney sweep does more than simply clean out the flue. Although an important part of the job, a licensed / certified chimney expert will also inspect the chimney structure and fireplace to ensure that both are structurally sound and free of obstructions and combustible deposits. This may include dangerous creosote deposits as well as soot and dust. A good inspection also ensures that your fireplace and chimney meets all local fire and building codes.
The flue will also be checked for damage during the annual inspection. Once the initial inspection is completed, the chimney sweep will clean the chimney and flue of all dust, soot and creosote found.
How to clean a chimney
The primary purpose of a chimney sweep is to identify potential problems and remove dust, soot, ash from the chimney. A chimney sweep can work from either inside (going in through the base of the fireplace), or from the top of the chimney. In some cases the sweep may utilize both entrances. Either way is acceptable and usually depends on the size and condition of the chimney, access availability, and weather conditions.
When cleaning the chimney, expect your sweep to follow these basic steps:
- Setting drop clothes in the area to lay equipment on and catch any dust or soot that may escape during the cleaning process
- Setting a vacuum to the contain the dust and soot in the fireplace
- Inserting a fitted brush inside the interior flue with flexible rod system to the brush to allow the sweep to make its way through the entire system
- Cleaning the interior of the flue and chimney, getting rid of all hazardous build-up
- Giving you a complete inspection report for your records
- Completing any small repairs to the system which may have been found during the initial inspection
- Scheduling your next inspection

Chimney fires cause over 14,000 fires every year in the U.S. and nearly $35 million in property damage, according to the National Fire Protection Association. What’s even more startling is that most of these chimney fires burn and extinguish themselves and initially are unnoticed by homeowners. Damage produced by an undetected chimney fire is only discovered later when the homeowner has a chimney sweep company come to their home and provide a chimney sweep and inspection service. The NFPA recommends that chimneys be swept every year. It is important to hire a professional company that knows how to sweep a chimney. Homes in Silver Spring, MD need chimney sweeps in the same manner that every other home requires.
Here are some reasons why homes need a chimney sweep every year
1. Creosote buildup in the chimney
Creosote buildup is responsible for the majority of chimney fires. Smoke emitted by burning fossil fuel or wood rises into your chimney where it cools and produces volatiles, carbon, and water condensation. Unless removed, this condensation quickly converts into an oily, black residue chimney sweeps call creosote.
Creosote develops in three stages: 1) crunchy or porous soot; 2) a sticky, tar-like substance; 3) a hard glaze that is real creosote. Be aware that creosote remains highly combustible in any stage and can almost instantly produce a dangerous, volcanic-like chimney fire.
Conditions that promote creosote buildup include:
- Flues too large for unlined inserts (wood-burning appliance)
- Restricted or reduced air supply
- Burning rain-saturated or unseasoned wood
- A surface flue temperature that is cooler than normal
2. Animals nest can clog the chimney flue
Even if you only use your chimney occasionally, Birds, bats, squirrels and raccoons may clog the flue their nests. In fact, chimneys with the least amount of use of the most common targets of animals seeking a place to build nests.
3. Chemicals alone won’t do the job
The Chimney Safety Institute of America (CSIA) does not recommend relying on chemicals to clean your chimney. Commercial chimney cleaning products claim to remove creosote from chimneys via fire-supported catalytic action. However, the CSIA states that these chemicals should not be used to replace a thorough cleaning and inspection performed by a professional chimney sweeper.
4. Unseen mortar and/or flue tiles problems
Broken or cracked flue tiles, deteriorated mortar and missing bricks may be inconspicuous to homeowners. Chimney sweepers are trained to detect the smallest hairline cracks and other minor damage that, when exposed to fiery heat, could cause a fast-moving fire.
5. Industry standards require an annual chimney sweep
The National Fire Protection Association’s standard recommends that chimneys be inspected every year. This requirement is detailed in NFPA standard 211.
Tips for Preventing Chimney Fires
Only burn seasoned wood. The ideal moisture content of seasoned wood should be between 15%-20%. The best way to find out the moisture content is by using a moisture meter.
Use only dry kindling or clean newspaper when starting a fire. Never use kerosene, gasoline, wrapping paper, cardboard boxes and especially, your Christmas tree!
Finally, the Chimney Safety Institute of America strongly urges homeowners to have their fireplaces, vents and chimneys inspected at least one a year by an experienced chimney sweeper for “correct clearances, freedom from deposits and soundness“.
