Crown sealing, patching and rebuilding

Preparing the crown surface before a coating

A coating bonds only as well as the surface beneath it. Loose particles, dirt and old flaking material are brushed off first. Debris and organic growth are removed so the membrane sits on concrete, not on dust.

Tell us if anyone has painted or sealed the crown before. An earlier layer that is peeling may have to come off, because a new coat cannot hold a failing one in place. We explain what the preparation involves so the scope is clear before work begins.

Layers of old patches on a crown

Some crowns carry several patches from different visits. Each layer may be a different material, and they do not always bond to each other. Water can travel between layers and appear somewhere unexpected.

Tell us what you know about earlier crown work, even if it is only a rough idea. We assess whether the layers can stay or need to come off. A new product applied over a stack of failing patches can only perform as well as the weakest layer underneath it.

Crown work and a damaged flue liner

The crown surrounds the top of the flue liner, but it does not repair the liner. A cracked tile, a gap between tiles or a liner that has broken at the top are flue problems. They need their own assessment.

When we see liner damage during crown work, we describe it and explain its effect on the crown plan. Sometimes the liner top must be dealt with before the new crown can be sealed to it. That work is priced separately so you can see how the two jobs relate.

Planning access to the chimney top

Every crown job starts with safe access. Roof pitch, the roof covering and the chimney's position all shape how we reach the top and where material is staged. A chimney on a steep or fragile roof may need more protection.

We look at access during the free inspection and explain it in the estimate. If ladders need to stand in a garden bed or over a walkway, we tell you in advance. Mention anything fragile near the chimney, such as solar panels or skylights, so the plan accounts for it.

Answers about chimney crown work

Is a mortar wash on top of my chimney the same as a crown?

It sits in the same place, but a thin sloped mortar topping is not built like a formed crown. Brick industry guidance warns that thin, feathered edges are more prone to deterioration. We check whether yours can be coated or should be replaced.

What does the free inspection include for a chimney crown?

We look at the crown surface, edges, slope, overhang and the seal at every flue, plus the cap fixings and the brick just below. You hear the findings on site and receive a free written estimate that keeps each item separate.

What should I tell you when I call about the crown?

Mention what you have seen, such as concrete pieces on the roof, a stain inside or cracks visible from the yard. Tell us about earlier patches or coatings and any appliance that vents through the chimney.
