Chimney Repair & Repointing Northampton

A chimney stack takes more weather than almost any other part of a roof, standing exposed above the roofline and bearing the brunt of wind, rain and frost. Mortar joints and brickwork that would last decades elsewhere on a house tend to fail here first, and a chimney in poor condition is one of the more common sources of leaks lower down the roof too.

We repair and repoint chimneys across Northampton and Milton Keynes, whether that's routine maintenance on an ageing stack or addressing a chimney that's actively causing a leak.

Common Chimney Problems

Because a chimney stack sits above the roofline, problems here can go unnoticed from ground level for a long time, which is one of the reasons we'd recommend having a stack checked as part of any wider roof inspection, not just when there's an obvious problem.

  • Perished or missing mortar joints, known as repointing being needed, which lets water into the brickwork itself

  • Cracked, leaning or unstable stacks, often a sign of long-term water damage to the internal structure

  • Damaged or missing chimney pots and cracked flaunching (the mortar bed around the base of the pots)

  • Failed flashing where the chimney meets the roof, a very common source of leaks lower down

What Repointing Involves

  1. Raking out failed or perished mortar joints to a proper depth, rather than simply skimming over the surface

  2. Repointing with a mortar mix suited to the age and type of the brickwork, since the wrong mix can cause further damage over time

  3. Checking and repairing flaunching around chimney pots

  4. Checking the surrounding flashing and roof tiles while access is in place, since chimney and leadwork problems often go together

When Repair Isn't Enough

A stack that's significantly leaning, cracked through the brickwork rather than just the joints, or showing signs of internal structural damage may need partial or full rebuilding rather than repointing alone. We'll assess this honestly during an inspection and explain what's involved before recommending the more significant work.

Why Choose Bridgework

  • Proper assessment of whether repointing is sufficient or a rebuild is genuinely needed

  • Mortar mixes matched to the age and type of brickwork rather than a one-size-fits-all approach

  • Checking surrounding flashing and tiles as part of any chimney work, since the two are closely linked

  • A clear quote before work starts

Chimney Repair FAQs

Visible gaps or crumbling in the mortar joints, mortar debris in the guttering below, or damp patches appearing near the chimney breast internally are all signs worth having checked.

It can be, since a significantly leaning stack may indicate structural damage that could eventually lead to instability. If you notice a visible lean, it's worth having it inspected promptly rather than waiting.

Most domestic chimney repointing can be completed within a day once scaffolding or access equipment is in place, though this varies with the size of the stack and extent of the work needed.

Yes, since chimney flashing and brickwork issues are closely related, we'll check the surrounding lead and tiles while access is already in place and flag anything else that needs attention.
