In general, masonry work that has been properly constructed requires only very minimal maintenance or repairs to hold it's good condition. On older structure it will be much more likely that the joints between the brickwork and stone will be degraded and be showing signs of deterioration which can be attributed to any estimate of problems.

Problems that can cause your brickwork or masonry to deteriorate include moister damage from leaking roofs, damaged guttering and drain pipes or leaking plumbing. Ingress of moister at ground floor level due to inadequate damp proofing is a major cause of masonry damage, other problems may even affect sills, lintels, eves and parapets. Structural settling can also be devastating to brickwork.

Sometimes it can be the case that problems with masonry and brickwork arise due to poor workmanship of the primary Mason. Poor mixing of incorrect proportions can lead to frost damage and sulphate strike by soluble salts contained within the bricks themselves.

Sometimes issues of damp are hard to avoid. The normal evaporation of moister from the bricks and mortar can be affected restricting the normal evaporation process due to extreme shading by overhangs and close presence of adjacent buildings.

Before attempting to take on any heal or rehabilitation of your damaged brickwork or masonry, the basic causes of your single problems should be addressed. The estimate of the heal will be governed by the degree to which the decay has penetrated. In the worst circumstances partial rebuilding of the structure may be the only remedy. considered probing in to the bed joints of the building will be the best indication of the health of the brickwork. Where the mortar has wholly degraded it is a waste of time naturally to re-point and is often important to rebuild the whole structure.

Preparation of the mortar is preponderant as it may vary in aggregate widely agreeing to requirements, but the normal rule is that the strength of the mortar should never exceed the strength of the actual bricks themselves. Over strength mixing can lead to serious degradation of softer bricks and stone, this being attributed to the hard mortar resisting and restricting evaporation through its dense exterior prominent to saturated bricks, the affected brick work is then subjected to a hard frost and it will crack and break down the structure of the bricks.

There are many dissimilar types and styles of pointing. Flush pointing is a base finish on all fair faced work, both internal and external. Joints are filled flush to the masonry exterior forming no recess to accumulate dust. Struck and Cut style pointing is ordinarily internal and used to pick out the bricks in a feature, which is done by running a trowel along the bed joint and pressing in at the lower edge of the joint. Rounded or pail handle and weather struck pointing, recessed pointing and tucked pointing are just a few more examples of jointing methods used by builders over the last 2000 years, luckily most property in need of maintenance today was only built in the last 300 years. If you need to carry out re-pointing or replacing of brickwork or stone to a listed building in Nottingham you should be aware that all repairs must dry to a shade that is consistent to that of the primary property or you will be made to remove or color it until it does.
