How to Repoint a Chimney (User’s Guide)

A chimney is a necessary part of your home. It provides the essential function of venting smoke, heat, and other byproducts from your fireplace or stove to the outside world. The chimney also helps insulate your home against cold air in winter months. But what happens when there are problems with this crucial feature? For starters, you might notice that it’s not so easy for smoke to leave your house anymore. The result could be very unpleasant – including black soot stains on interior walls and an increased risk of fire hazards.

Repointing your chimney is an essential maintenance task. Without this, the cracks in the mortar joints will continue to grow and eventually break apart. This can lead to leaking, water damage, or worsea cracked brick that falls off of your roof! These are all signs that it is time for repointing services.chimney

What is repointing a Chimney and why should I do it?

Repointing a Chimney is simply filling in the gaps between bricks with mortar. This keeps water from seeping into your home, which can cause serious damage over time if left untreated.

Repointing your Chimney will also help keep it clean, which in turn can lengthen its life by years. The mortar fill helps prevent soot from being washed down the brick face of your home when there are heavy rains or snow melts. This keeps everything looking nice and neat. Repointing a chimney is an important part of routine maintenance that should be done every few decades to ensure you get the most out of this aspect of your home’s architecture for as long as possible!

How do I know if my Chimney needs repointed?

How to identify if your Chimney needs repointing?

A chimney is the most important part of any home. It keeps your house safe from fire and allows you to enjoy a nice fireplace or stove during those cold winter months. The only problem with this appliance, however, is that it can be damaged over time due to exposure and weather conditions. This damage mostly occurs at the top of the chimney where water seeps into its crevices and freezes when temperatures drop below freezing point – this causes expansion which damages mortar joints leading them to crumble away leaving behind gaps between bricks which allow for harsh winds inside your home as well as allowing smoke back out.

If such issues are not dealt with quickly they will eventually lead to further problems like carbon monoxide poisoning (due to lack of draft) and the house being filled with smoke.

How to Repoint a Chimney?

There are two main types of repointing methods which you can use: one is done by hand and other is done using an automated machine also called “pointing robot”. The later works like a human pointing mortar onto bricks but it does so much faster than any single person could ever do, making your chimney look good as new in no time! When doing this be sure to wear protective clothing (goggles and gloves) and mask over mouth and nose while working on the project – if not for yourself then at least for those who live inside that home or building where you will be doing your work. Make sure there are no children or pets around the project area as well – they might get hurt by falling bricks.

Tools needed for the job

In order to repoint a chimney, you will need the following tools:

  • A garden hose.
  • An iron stake.
  • A pointed trowel or grout knife – a long-handled pointed tool with a sharp edge on one side of its blade and a flat surface on the other for striking it with a hammer).
  • A bricklayer’s rubber mallet – this is different from your regular claw hammer as it has no claws; instead, it has two small projecting ears at either end of its head which are used to hold it in place while dismantling bricks). A stiff brush (a wire brush works best), some water, mortar mix and an old mixing bucket if possible. You can work without these but they make the job much easier.

Step-by-step instructions on how to repoint a Chimney

Clean your chimney and make sure it is dry. You can use a pressure washer or hose to clean the brick on the inside of the fireplace if needed.

  • Do not stand directly in front of an open fire while cleaning out your Chimney as you may inhale toxic gases from creosote deposits.
  • Remove any loose mortar from the joints around the base of your fireplace. You can use a wire brush or scraper to remove these deposits. Round off any sharp edges with sandpaper and wear gloves when doing this step as creosote is toxic if it comes in contact with skin. If you cannot find an area where there are no deposits, then do not worry about removing them all (the ones that are on top will be removed during repointing).
  • Use hydraulic cement mix to fill the gaps between bricks at the bottom of your Chimney before tuck pointing starts. Hydraulic cement does not shrink meaning that once it has dried out completely, there should be little movement allowing for greater strength over time so cracks on the Chimney do not reappear.
  • Lay a bed of mortar at the bottom of your Chimney to give yourself somewhere for repointing to start from. If you don’t have enough flat surface then lay bricks down on top of each other, side by side and make sure they are level with one another before laying any mortar in between them (this will create even more flat space). Make sure that there is about half an inch gap between the new layer and old brick work using a spirit level or straight edge tool if needed. You can use this same method when filling gaps around windowsills too as it creates a stronger structure over time which is less likely to show problems such as cracks again.
  • Do not stand directly in front of an open fire while cleaning out your Chimney as you may inhale toxic gases from creosote deposits.
  • Use hydraulic cement mix to fill the gaps between bricks at the bottom of your Chimney before tuck pointing starts. Hydraulic cement does not shrink meaning that once it has dried out completely, there should be little movement allowing for greater strength over time so cracks on the Chimney do not reappear.
  • Mix mortar and apply it with a trowel or spreader (think like spreading butter onto toast) in layers up against each brick which is about half an inch thick and repeat this step until all bricks are covered fully – make sure they stay wet during application by misting them with water every few minutes or you can also use a spray bottle. You will need to mix more mortar as the level of each layer goes up and it is best to do this in stages (mixing too much at once might dry out your mixture before you get chance to apply). Once completed, press down on all layers firmly with your trowel – but carefully – so that they bond together well over time which means greater strength overall.

Environmental Protection

Repointing a chimney is not an easy task. However, the environmental consequences of doing nothing are even worse. If you have cracks or gaps around your fireplace flue and damper, unwanted heat will escape through those openings instead of going up the chimney as it should. This means more fuel must be burned to make up for this lost heat which leads to increased pollution (CO) emissions (carbon monoxide). Not only that but air leaks can also contribute to deterioration in indoor comfort since warmer outside air enters your home thus increasing energy costs while simultaneously reducing humidity levels within your living space; leading to dry skin, nosebleeds and other undesired effects.

As you can see it is in everyone’s best interest to repoint a chimney. It will help the environment while simultaneously increasing energy efficiency and comfort within your living space. So before winter rolls around, check out these easy steps on how to repoint a chimney yourself!

Use a stiff putty knife to remove loose and flaking mortar from between bricks.

Clean the chimney using water, cleaning solution and scrub brush; rinse clean with garden hose or power washer (if available). This is to ensure you do not leave any debris in your new mortar bed which could interfere with bonding of the new repointing material. Make sure that all dust is cleaned away before applying fresh mortar!

Safety Tips

  • Always wear protective gear when repointing a chimney. Work gloves, eye protection and ear muffs are all necessary to prevent injuries while working with the brick mortar.chimney
  • When you’re not wearing your safety equipment, make sure to take care of yourself so that you don’t fall sick from breathing in toxic dust or other things found around a fireplace area.
  • Keep pets away from the area. Pets can cause accidents if they are not kept safe. Keep them in another room at all times when you’re repointing a chimney for this reason or tie up your pet so that is doesn’t get hurt.
  • Chimney repointing can be done with a few basic tools. A bucket, gloves and some sort of protective eyewear are the bare minimum items to have when you begin your project.

FAQs

What is a chimney?

A chimney is a metal or stone structure that goes from the exterior of your home up into the sky to allow smoke and fumes to escape. Chimes are an important part of any building’s design as they create natural ventilation for your fireplace, stove, furnace, water heater and more. Chimneys must be cleaned regularly as soot can build up inside which increases flammability risk. When this happens you should contact one of our professional repointing companies in New Hampshire immediately!

What is chimney repointing?

Repointing a chimney can be done through several different methods. When new mortar or caulk is applied to the brickwork of a masonry structure you are essentially “repointing” it. This results in an incredibly strong and durable seal which keeps water from entering your home, increasing fire risk and decreasing energy efficiency. The process of applying this mortar involves removing old material before new materials are installed with proper spacing around joints for expansion and contraction due to temperature variation between seasons. If not properly maintained improperly sealed joints will lead to damage over time such as cracks, spalling, delamination or even holes that allow insects into buildings!

How often should I have my chimney cleaned?

It’s important to clean the inside and outside of your home, especially when you use it regularly. Chimneys can be safely used for cooking fires, heating appliances and keeping our homes warm but they need to be properly maintained in order to operate at their top efficiency levels. For fuel-burning appliance cleaning we recommend using a professional repointing company every two years or so depending on factors such as usage frequency and type of fuels burned with them. If you notice that smoke is not exiting easily from the building then contact us right away since this may indicate there are serious problems with how solid your structure is!

How do I know if my chimney is structurally sound and safe for use?

There are a number of ways to tell whether or not your masonry structure is in good condition. The most important thing you can do when considering repairing any part of it yourself or hiring someone to complete the work on your behalf is inspecting the visible areas with expertise. This includes checking brickwork, mortar joints, flue lining and components such as flashing and crowns that extend over roofs. If these appear damaged then we recommend contacting one of our repointing companies right away! You should also check out how much space exists between bricks since this will help determine structural safety too – try removing some mortar from an area near where you’re standing and see if the bricks are held up by some other material underneath.

Why does it matter that I hire a repointing company?

Hiring one of our repointing companies in New Hampshire ensures that all work performed on your chimney meets local code requirements for safety, quality assurance and good practice standards. Our teams at Chimney Repair NH have years of experience providing re-pointing services so you can rest assured knowing they will be able to address any issues quickly before more serious problems start occurring with your structure. We also offer free inspections which allow us to inspect your building thoroughly without charging you anything upfront! We can also provide you with information regarding costs associated with various services to give you the best value for your investment.

Conclusion

Chimneys are an important part of any house, but if they’re not maintained properly or don’t have the right protection, they can become less effective. The bricks around your chimney will begin to crack and crumble after years of being exposed to weather conditions so it is recommended that you repoint them every two decades. This will also give you access to inspect for damage in areas where water may be leaking into your home.
