Professional Repointing Services in Hemel Hempstead

Mortar is designed to sit between the bricks, helping to keep the wall stable and reducing the amount of moisture that enters the masonry. Over time it can deteriorate because of weather exposure, frost, persistent moisture, age, previous poor repairs, unsuitable hard cement mortar or movement in the wall.

When joints become weak or incomplete, the wall may lose protection. Water can enter more easily, and the face of the surrounding bricks may begin to break down. Repointing removes the failed outer mortar and replaces it with a suitable new joint. When completed properly, it can improve both the condition and appearance of the brickwork.

A proper repointing job involves more than placing new mortar over the surface. The process typically includes inspecting the brickwork and existing mortar, identifying the areas that require attention, removing failed mortar to a suitable depth, cleaning loose dust and debris from the joints, preparing the wall appropriately, applying compatible new mortar, finishing the joints in a profile suited to the property, cleaning the surrounding brick faces and protecting the new mortar while it cures.

Mortar should not simply be chosen because it is strong - it must be suitable for the bricks and the building. In some older properties, a mortar that is too hard can trap moisture or cause the softer brick faces to deteriorate. The correct choice depends on the age of the building, the type of bricks, the condition of the existing mortar, exposure to weather, the required joint finish and any previous repairs. Where specialist conservation advice is needed, this should be identified before work begins.

The quality of repointing depends heavily on preparation. If failed mortar is not removed properly, or if new mortar is applied only as a thin surface layer, the repair may not last. Our approach focuses on proper joint preparation, careful control of dust and debris, appropriate mortar, consistent joint depth, a suitable joint profile, clean brick faces and sensible protection during curing. We aim to leave the wall looking cared for, not heavily altered.
