Full removal: Complete stack and breast removal through loft or entire property (in coordination with builders).
Stack reduction: Lowering unsafe or leaning chimneys for safety while retaining part of the structure.

Chimney Removal FAQs

Do I need planning permission to remove a chimney?

Usually not for partial removals above the roofline, but full removals may require building regulation approval. We’ll guide you through it.

Can you remove just the top part of my chimney?

Yes, partial removals are common and cost-effective for redundant flues that still support internal walls.

Will removing a chimney cause leaks?

No — we fully re-tile, felt, and seal the roof to make sure it’s watertight and neat.

What happens to the debris?

All bricks and rubble are cleared from site responsibly and recycled where possible.

Can you remove a shared chimney between two houses?

Yes, but it must be done carefully and agreed with the neighbour. We handle party-wall arrangements if needed.

How long does chimney removal take?

Typically 1–2 days for a small stack, up to a week for full internal and external removal jobs.

Will chimney removal lower my insurance premiums?

It can — insurers often see it as a reduced fire and leak risk, but you should check with your provider.

Chimney Cowl & Cap Installation in Dartford

Chimney Cowl & Cap Installation in Dartford – Protect Your Chimney from Rain and Pests

If your chimney is letting in rainwater, draughts, or nesting birds, it’s time to fit a proper cowl or cap. S Harris Roofing supplies and installs quality chimney cowls and caps across Dartford to stop leaks, improve safety, and extend the life of your chimney stack.

Why Fit a Chimney Cowl or Cap?

A chimney cowl or cap sits at the top of your chimney pot to keep out rain, birds, and debris while allowing proper ventilation. Without one, you’re exposed to water ingress, downdraughts, and blockages that can cause smoke blowback or damp issues indoors.

Prevents rain and moisture entering your flue
Stops birds, squirrels, and debris from nesting
Improves ventilation and prevents smoke blowback
Reduces heating loss from open flues
Helps prolong chimney lifespan

Types of Chimney Cowls & Caps We Fit

Rain cowls: Prevent rain entry and downdraughts while maintaining airflow.
Bird guards: Stop birds and small animals from nesting inside the flue.
Anti-downdraught cowls: Ideal for windy or exposed properties in Dartford.
Solid caps: Seal off unused chimneys to prevent heat loss and moisture.
Custom stainless steel cowls: Durable, long-life options for coastal or high-exposure homes.

How Much Does Chimney Cowl Installation Cost in Dartford?

Prices depend on the number of pots, access height, and cowl type. Here’s a quick guide:

Service	Typical Cost	Notes
Standard rain cowl supply & fit	£120 – £180	Galvanised or aluminium cowl installed securely
Stainless steel anti-downdraught cowl	£180 – £260	Ideal for windy areas or coastal exposure
Solid cap for unused flue	£100 – £160	Includes vent holes for moisture control
Multiple pot installation (2–4 pots)	£200 – £400	Includes safety access and fitting per pot

Free quotes available: Book your survey for a fixed written price with photos of the finished work.

Our Chimney Cowl Fitting Process

Inspection: Check pot condition and ensure correct cowl type for your flue.
Recommendation: Advise on the best model for ventilation and weather exposure.
Safe fitting: Secure ladder or scaffold access for safe installation.
Installation: Fit cowl or cap using stainless steel fixings or strap banding.
Final check: Test for stability and airflow, take before/after photos.

If your chimney also needs repointing or flashing repairs, we can carry out all works in one visit for cost efficiency.

Experienced installers: Hundreds of cowls fitted on homes across Dartford and Kent.
Quality materials: Stainless steel and weather-resistant designs only — no cheap imports.
Fully insured: Work at height carried out safely and responsibly.
Fair prices: Up-front written quotes, no hidden extras.

Chimney Cowl & Cap FAQs

Can a cowl stop rain from getting in?

Yes. A properly fitted rain cowl stops most water ingress while still allowing your chimney to breathe.

Do you fit cowls on tall or difficult-to-access chimneys?

Yes. We have the equipment and experience to work safely on all property types, including tall or steep roofs.

Will a cowl stop birds from nesting?

Absolutely. Bird-guard cowls are designed specifically to keep out pigeons, jackdaws, and other nuisance birds.

How long do chimney cowls last?

Galvanised models typically last 8–10 years; stainless steel versions can exceed 20 years with no maintenance.

Do I need planning permission?

No — chimney cowls and caps are classed as minor alterations. We just ensure they comply with ventilation and flue type requirements.

Can you remove or replace old cowls?

Yes. We safely remove old rusted or damaged cowls and replace them with modern, secure versions.

What’s the best type of cowl for solid-fuel fires?

Anti-downdraught or rotating cowls work best, as they improve draw and prevent smoke blowback in windy conditions.

Chimney Lead Flashing Repairs in Dartford

Chimney Lead Flashing Repairs in Dartford – Stop Roof Leaks at the Source

Noticing water marks near your chimney breast or in the loft? Nine times out of ten, it’s failed lead flashing. S Harris Roofing provides professional chimney lead flashing repairs across Dartford to seal out the weather and protect your home.

What Is Lead Flashing & Why It Fails

Lead flashing is the protective sheet that bridges the gap where your chimney meets the roof. Over time, flashing can split, lift, or pull away if it was poorly detailed, fixed with the wrong sealant, or stressed by movement and weather.

Common failures: split lead, loose step flashing, missing soakers, dried/cracked mortar chases, failed sealants.
Typical symptoms: damp patches on ceilings/walls, musty loft insulation, staining around the chimney breast.

Chimney Lead Flashing Repair Costs in Dartford

Exact pricing depends on access, stack height, and the extent of damage. Here are straightforward ballparks:

Lead Flashing Task	Typical Price Range	Notes
Re-seal mortar chase & minor re-dress	£180 – £350	For small lifts/splits with good base lead
Replace apron or step flashing (single face)	£300 – £550	Includes cutting chases and fixing correctly
Full chimney re-flash (apron, steps & soakers)	£650 – £1,100	Best for recurring leaks / worn-out lead
Re-flash + repointing to chimney faces	£800 – £1,400	Bundle to solve both causes of ingress

Next step: Book a free inspection and fixed quote. Request a visit and we’ll confirm the exact price after a safe survey.

How We Repair Chimney Lead Flashing (Properly)

Survey & photos: Identify split/loose lead, check soakers and mortar chases.
Preparation: Lift tiles as required, remove failed sealants, rake out chases cleanly.
New leadwork: Fit correctly sized code 4/5 lead (as appropriate), with stepped flashing and individual soakers.
Fixing & sealing: Secure with appropriate fixings and chase seal (lead-compatible), then neatly dress for water runoff.
Finishing: Re-bed tiles, tidy the work area, provide before/after photos.

If the brick joints are also failing, we’ll recommend repointing to stop the problem returning.

Why Choose S Harris Roofing in Dartford

Leadwork specialists: Proper step flashing, soakers and apron detailing — no shortcuts.
Local & reliable: We know Dartford’s property styles and typical weak points.
Transparent pricing: Clear written quotes, no hidden extras.
Quality materials: Correct lead codes and compatible sealants for long-term performance.
Guaranteed repairs: Workmanship backed by our guarantee and photo evidence.

Lead Flashing Repair FAQs

Can you repair flashing without scaffolding?

For low, accessible stacks, yes — we can often work safely from ladders/towers. Taller stacks or complex roofs may require scaffold for a proper job.

Do you use lead or alternatives?

We primarily use lead due to its longevity and malleability. Where specified, we can fit lead-alternative systems — we’ll advise what’s best for your roof.

Will new flashing stop my leak completely?

If flashing is the cause, yes. If mortar joints or chimney caps are also failing, we’ll address those in the same visit to guarantee a watertight result.

How long does a re-flash take?

Minor re-dress/re-seal: a few hours. Full re-flash with soakers: typically 1 day, depending on access and weather.

What lead code should be used?

Usually code 4 or 5 depending on span and exposure. We follow best practice so your flashing lasts.

Do you provide photos and a guarantee?

Yes — you’ll get before/after photos and a written guarantee on our workmanship.

Chimney Re-pointing in Dartford

Chimney Repointing in Dartford – Stop Leaks Before They Worsen

If your chimney mortar is cracking or crumbling, it’s time to act. Weather and age can wear down the joints that hold your chimney together, letting water in and weakening the structure. S Harris Roofing offers professional chimney repointing in Dartford to restore strength, prevent leaks, and extend the life of your roofline.

Why Chimney Repointing Matters

Mortar joints protect the brickwork from water penetration. When they fail, moisture seeps in, leading to internal damp, frost damage, and even chimney instability. Repointing replaces the old, damaged mortar with fresh, properly mixed material to keep your chimney weatherproof and structurally sound.

How Much Does Chimney Repointing Cost in Dartford?

Most chimney repointing jobs in Dartford fall between £350 and £1,100, depending on size, height, and condition. Small patch repairs are cheaper, while full four-face repointing on a tall stack can reach the upper end of that range.

Minor repointing (1–2 faces): £350 – £500
Full stack repointing: £600 – £1,100
Repointing with new lead flashing: £800 – £1,400

All quotes are confirmed after a free roof inspection — no guesswork, no hidden extras. Request your free quote today.

Benefits of Professional Chimney Repointing

Restores your home’s external appearance
Maintains property value and safety

Our Chimney Repointing Process

Inspection: Assess the condition of joints, bricks, and leadwork.
Preparation: Rake out loose mortar to the correct depth without damaging bricks.
Repointing: Apply a matching mortar mix suited to the brick and age of the property.
Finishing: Brush and clean joints for a neat, weather-sealed finish.
Final check: Ensure all flashing, pots, and cowls are secure.

Local to Dartford: We know the typical property types and what mortar mix works best.
Quality materials: Proper sand/cement or lime-based mortars as appropriate.

Chimney Repointing FAQs

How do I know if my chimney needs repointing?

Look for crumbling mortar, visible gaps between bricks, or vegetation growing out of joints. These are signs the mortar has failed and needs replacing.

Can you repoint just one side of a chimney?

Yes. We can target only the weathered faces if the rest is still sound. It’s a cost-effective solution when damage is localised.

How long does chimney repointing take?

Most repointing jobs are completed in one to two days, depending on the size and height of the stack.

Does repointing stop chimney leaks?

It often does, but if lead flashing or haunching is also failing, we’ll repair those at the same time to guarantee a watertight result.

What type of mortar do you use?

We match the original mortar as closely as possible — using lime mortar for older properties and modern mixes where appropriate.

Do you provide a warranty on chimney repointing?

Yes, all repointing and associated repairs come with a written workmanship guarantee for your peace of mind.

Can you repoint during winter?

Yes, as long as the temperature stays above freezing and conditions are dry. We plan around weather for proper curing.

Chimney Repair FAQs

How quickly can you attend a chimney leak in Dartford?

For active leaks, we aim to survey within a few working days. If water ingress is severe, we can arrange temporary weatherproofing while we book the repair.

Do I always need scaffolding for chimney repairs?

Not always. Minor lead or pointing work can sometimes be completed from ladders with proper safety measures. Taller stacks or full rebuilds usually require scaffold.

Will repointing stop my leak?

If the leak is caused by failed mortar, repointing helps. If the issue is split lead flashing or a missing cowl, we’ll address those specifically. We fix the cause, not just the symptom.

What mortar do you use for repointing?

We match the correct mortar type to your brick and age of property, avoiding overly hard mixes that can damage old brickwork.

Can you replace damaged chimney pots and add a cowl?

Yes. We can replace pots, re-bed them securely, and fit the correct cowl or cap to prevent rain ingress and bird nesting.

How long do chimney repairs take?

Small lead or pointing jobs can often be completed in half a day to a day. Rebuilds and removals take longer depending on scope and access.

Do you provide photos of the work?

Yes. We supply before and after photos so you can see exactly what was done.
