Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterMortar Repointing in Downers Grove, IL
Mortar repointing in Downers Grove typically runs between $400 and $1,800 depending on how much joint surface needs attention, chimney height, and whether the existing mortar has to be ground out or can be hand-chased. Most jobs on a standard two-story home are completed in a single visit. If you’re seeing crumbling joints, white mineral streaks on the brick face, or gaps you can poke a finger into, repointing is almost certainly the right fix – and doing it before the freeze-thaw cycle gets another shot at those cracks will save you from a much larger repair bill.
At Emberly Chimney Cleaners Downers Grove, we’ve worked on chimneys across DuPage County since 2009, and repointing is one of the most common chimney repairs we find after a camera-scan inspection. Corrine Halstead built this company around one idea: you get a written price, a written scope, and a written warranty before anyone touches a single joint. That’s Haven Standard Clause 1, and it applies to every repointing job we do. Call us at (331) 253-4980 – a live person picks up, any time of day.
Mortar repointing is part of our broader Chimney Repair in Downers Grove service, and it’s often the first thing we recommend when a Level 2 inspection turns up joint erosion before structural damage has had time to set in.
When You Need Mortar Repointing
- Crumbling or absent mortar joints: If you can see daylight between courses of brick, or the mortar crumbles when you press a finger against it, the bond is gone. In Downers Grove, the clay-heavy soil and our hard freeze-thaw cycles – we routinely see 20 or more freeze-thaw events between November and March – accelerate joint erosion faster than in warmer climates.
- White staining (efflorescence) on the chimney face: That chalky white residue is mineral salt being carried to the surface by water that’s getting in through failed joints. It’s not cosmetic – it’s a sign water is moving through the masonry.
- Gaps or voids along the crown-to-brick transition: Where the chimney crown meets the first course of brick is one of the first places mortar opens up. Water gets in there, freezes, and widens the gap every winter. We see this on a large share of chimneys in the George Street and Fairview neighborhoods, particularly on homes built in the 1960s and 1970s.
- Brick faces spalling or flaking: Spalling – where the face of a brick pops off or flakes – is almost always caused by water that entered through failed mortar joints, froze inside the brick, and expanded. By the time bricks are spalling, the mortar has typically been failing for years.
- Interior water staining near the firebox or on ceilings: Water that enters through open joints doesn’t always run straight down the outside of the chimney. Sometimes it tracks inward, staining ceilings or the smoke chamber walls. If your inspector finds wet masonry inside the firebox, deteriorated joints on the exterior are the first place to look.
- A recent Level 2 inspection flagged joint erosion: Our camera scans have flagged mortar erosion on chimneys that looked perfectly fine from the ground. If a written inspection report calls out joint deterioration – from us or any other inspector – don’t leave it until next season. Downers Grove winters are hard on open joints.
Our Mortar Repointing Process
- Camera-scan inspection and photo documentation first: Before we quote a single linear foot of repointing, we run a Level 2 NFPA 211 camera inspection and photograph every course of joints we’re recommending for work. You see what we see. The photos become part of your permanent file under Haven Standard Clause 4. This isn’t an optional add-on – it’s how every visit works.
- Written price, scope, and warranty delivered before work starts: Once we know exactly what we’re dealing with, we put the price in writing – which joints, how deep, what mortar mix, and how long the work is guaranteed. That document comes to you before any tool comes off the truck. Haven Standard Clause 1. No revisions after the fact.
- Joint removal to sound depth: Repointing over failing mortar is not repointing – it’s cosmetic work that fails again in a season. We cut or grind failed mortar to a minimum depth of three-quarters of an inch (and often deeper where the erosion has undercut the brick). On historic masonry, where the original mortar is softer lime-based mix, we hand-chisel rather than grind to avoid cracking the brick face.
- Mortar matching and application: The replacement mortar has to match the original mix’s compressive strength – if it’s harder than the surrounding brick, it transmits stress back into the masonry and causes more cracking. We specify the correct Type N, Type S, or lime-based mortar for your chimney’s age and construction, and we pack each joint in lifts to prevent shrinkage voids. On older homes in Downers Grove, particularly those in the Ellsworth neighborhood, we frequently encounter original lime mortar that requires a matched mix rather than modern Portland-heavy compounds.
- Tooling and final inspection: Once the mortar reaches the right set, we tool each joint to match the original profile – concave, flat, or weathered – so the finished surface sheds water rather than catching it. We photograph the completed work and add it to your documented photo record.
- Written completion record delivered to you: You receive the before-and-after photo set, the written scope of work completed, and your warranty documentation. If anything isn’t right within 365 days, the 365-Day Done Right Promise covers it – we make it right, no argument.
BeforeAfterMortar Repointing Pricing in Downers Grove
Mortar repointing costs in Downers Grove depend on four main variables: how many linear feet of joint need replacement, how deep the removal needs to go, the chimney’s height and accessibility, and whether any scaffolding is required to reach the work safely. Here’s a straightforward breakdown of what we typically see in this market:
| Scope of Work | Typical Price Range |
|---|---|
| Spot repointing – isolated joint failure, 1 to 2 linear feet | $400 – $650 |
| Partial repointing – one or two exposed faces of the chimney stack | $650 – $1,100 |
| Full chimney repointing – all four faces, full stack above roofline | $1,100 – $1,800 |
| Historic lime mortar matching (hand-chased, matched mix) | Add $150 – $300 to applicable range |
| Scaffolding for chimneys over two stories or steep-pitch roofs | Add $200 – $400 to applicable range |
These are honest ranges based on what we’ve actually quoted in Downers Grove over the past several years. The number on your written estimate before work starts is the number you pay – no fuel surcharges, no “materials cost more than expected” surprises after the fact.
One thing worth knowing: repointing is almost always more cost-effective than waiting. A chimney where joints are failing but the brick is still intact is a $400 to $1,800 repair. A chimney where the water has been getting in long enough to cause spalling bricks, rot the wood frame behind the masonry, or saturate the smoke chamber is a different project entirely. We’ve given second opinions on written estimates from other contractors in the Downers Grove area, and in several cases the customer brought us a quote for a partial rebuild that was actually a repointing job in better lighting.
If you’ve already got a written estimate from another contractor, bring it to us. Our Free Second Opinion is exactly that – we look at the same chimney, give you our written assessment, and tell you what we’d charge. No obligation.

Why Downers Grove Chimneys Need Repointing More Often Than Homeowners Expect
Downers Grove sits in USDA Hardiness Zone 5b, which means sustained cold – lows that regularly drop below 0 degrees Fahrenheit in January and February. The real damage to mortar joints isn’t cold itself; it’s the repeated cycling between freezing and thawing. Water gets into a hairline crack in the mortar, freezes and expands, opens the crack slightly, then thaws. The next freeze pushes a little further. Over five or ten winters, what started as a hairline becomes a visible gap.
The problem is more pronounced on the north and east faces of a chimney, which get less direct sun and stay wet longer after rain or snow. If your chimney faces the Belmont Road corridor or sits in a lot with mature tree cover – common in the older sections of Downers Grove near the Main Street Metra station – the shading extends the wet period and speeds up the cycle.
Mortar mix also matters. Homes built in Downers Grove before 1970 typically used softer lime-based mortar, which is actually more flexible and self-healing than modern Portland cement mixes. The problem comes when someone repoints with hard Portland over soft lime – the harder mix doesn’t flex with the masonry, stress concentrates at the old-joint boundaries, and the bricks themselves can crack. Our technicians identify the original mix before specifying the replacement, and we source materials through our supply relationships – including Copperfield and Gelco product lines – specifically to get the right mix at a price that doesn’t get passed on with a markup.
What You Walk Away With After a Repointing Job
Documentation isn’t an afterthought here. Under Haven Standard Clause 4, every visit generates a photo record – before the work, during joint removal, and after tooling. That archive matters because:
- It’s your record if you sell the house and a buyer’s inspector asks about chimney maintenance history.
- It documents the condition of the masonry before we touched it, which protects both of us if there’s ever a question.
- It gives us a baseline for the next inspection – we can see exactly what was done and when, rather than starting fresh every time.
- Your homeowner’s insurance carrier may ask for documentation of chimney maintenance. A photo record is more useful than a verbal claim.
You also receive the written warranty for the repointing work specifically. The 365-Day Done Right Promise means that if joints we repointed fail – mortar falls out, bond fails, anything that points back to workmanship – we come back and make it right. That’s in writing, on your paperwork, before the job starts.
A Note on Safety and Who Should Do This Work
Chimney repointing requires working at height, on or near a roof surface. A significant portion of repointing work on two-story homes in Downers Grove requires roof access or scaffolding – neither is a casual DIY project. The fall risk is real, and working on an angled roof surface near a chimney stack is a different situation from cleaning gutters from a ladder. We don’t say this to scare anyone; we say it because it’s what a straight answer looks like. If you’re comfortable on a low-pitch roof and the affected joints are accessible and limited, a handy homeowner can handle spot repointing. For anything involving height, a steep pitch, or more than a few square feet of joint surface, call a trained crew with the right equipment and the right insurance.
FAQs – Mortar Repointing in Downers Grove
How much does mortar repointing cost in Downers Grove?
Mortar repointing in Downers Grove typically costs between $400 and $1,800 for a standard residential chimney, depending on how many faces need work, chimney height, and whether scaffolding is required. Spot repointing on one or two joints runs $400 to $650; a full stack repoint on all four faces runs $1,100 to $1,800. Your written estimate from Emberly Chimney Cleaners Downers Grove will show you the exact number before any work begins, so you know how much chimney repair costs upfront. Call (331) 253-4980 to schedule a free on-site estimate.
Can you just repoint over old mortar, or does the old mortar have to come out?
The old mortar has to come out to a sound depth – at least three-quarters of an inch – before new mortar can be packed in. Applying new mortar over degraded mortar gives the new material nothing solid to bond to, and it typically fails within one or two winters. Proper repointing means cutting or grinding the joint until you reach sound material, then filling in lifts. It’s more work than a surface coat, but it’s the only approach that holds.
How do I know if my chimney needs repointing or a full rebuild?
Repointing is the right call when the mortar joints are failing but the brick units themselves are still sound – no spalling, no structural shift in the stack. A rebuild becomes necessary when bricks are cracked through or spalling badly, when the stack has moved or leaned, or when water infiltration has been going on long enough to damage the structural courses. The line between the two isn’t always obvious from ground level, which is exactly why we run a camera-scan inspection before quoting anything. If you have a written estimate from another company that recommends a rebuild, bring it in – our Free Second Opinion will tell you whether that’s actually what the chimney needs.
How long does mortar repointing last?
Properly specified and installed mortar repointing on a Downers Grove chimney should last 20 to 30 years under normal conditions. The two biggest factors that shorten that lifespan are using a mortar mix that’s too hard for the surrounding brick (which transfers stress into the brick face rather than the joint) and leaving a chimney cap or crown in poor condition, so water continues to enter from the top. We address both during every repointing job – if the crown needs attention, we’ll put it in the written scope rather than let the repointing fail early from above.
