Farmhouse in Manchester before Lime Pointing

Lime Pointing Farmhouse Gable & Rear Stone Walls in Bury, Manchester.

Lime Pointing a stone build farmhouse in Manchester. This Period Property situated on the hill above Manchester had been like so many others, pointed with a cement based mortar & painted with a modern masonry paint. The internal stone walls of this property were some of the wettest I have seen. After scraping out some of the original lime mortar, when squeezed water dripped out.

Gable Wall before Lime Pointing In this Restoration project we applied Lime Pointing to the rear & gable stone walls. The first task was to erect a access scaffold around the job. This proved difficult as the access lane is about 1 mile long & rough. The sub contracted scaffolding company had to bring 5 transit loads up rather that 1 lorry. The building required the cement based pointing removing. Our specialist contractors working on this heritage building in Manchester used hand tools to remove the existing pointing mortar. This is not a Listed Building in Manchester but our Building Contractors used all the necessary skilled traditional techniques. Listed buildings in Manchester requires Specialist experts to Restore them. At UK Restoration Services we use a highly skilled work force to Preserve historic buildings.
Removing Cement Pointing from Stone Wall We started by removing the cement based mortar for the rear stone elevation. We used small air tools to do this. Once we started to remove the cement we discovered that the wall had large sections of loose masonry. There loose stones had to be removed and re-bedded using a Lime Mortar. Our Specialist Restoration Contractors used small raking tools to remove the remaining cement mortar from the joints. The stone wall on this Manchester building required hours of work to remove the mortar. Loose masonry had to be re-built with lime mortar. Our Stone Masons in Manchester used Traditional Lime Mortar, this was a Hydraulic lime mortar. The Masonry was in a very poor state and required carefully Restoration by our Stone Masons.
Loose Masonry Stone Wall

This is one of the many areas that need to be rebuilt. The original Lime Mortar joints had decayed so much the stones (masonry units) had become loose. Most of the internal rubble fill to the stone wall had been lost via previous alterations.

Our Restoration team replaced the internal rubble fill, using a lime mortar to secure the rubble. We then re-fit the original stones bedded in lime mortar. The Stone Replacement work added a additional 2 weeks to the project.

Stone wall ready for lime pointing The small hole in the centre of the wall ended up being around 2 sqm, we had to install additional structural props to the wall. The Structural work involved on this farm house in Manchester took 2 additional weeks. We did not require the use of resin anchor ties system like Helifix or Helical. The Stone Masons working on this building in Manchester replaced loose stones with lime mortar. Our Masonry Contractors working this none Listed Building in Manchester also replaced damaged sections of Masonry with like for like replacements. Specialist Masonry Contractors working on this Manchester Heritage building had to protect the lime mortar for the weather elements.
Sandblasting Stone Wall in Manchester

We a low pressure sandblaster to remove the masonry paint from the wall. Sand blasting is not a process we would normally use, but due to site conditions & client requirements we had only this option. We used a local Manchester based Sandblasting company for the sandblasting work. One of our Restoration Team was acting as bankman to ensure minimal damage to the Stonework. We now have a Low Pressure Wet Blasting machine which we would use now on any similar work. Sandblasting in Manchester this stone wall had to have the paint layers removed.

Picture showing void in the stone wall, these void were filled with a Lime Mortar and packing stones. Lime Mortar is ideal for use on this kind of traditional period building, the property is not a listed building but still needs to breathe. The Hydraulic Lime Pointing Mortar allows moisture to pass through, allowing any dampness in the building to evaporate.

Dampness in old buildings around the Manchester area, tend to be because the exterior of the building has been pointed with a cement mortar. The Damp can lead to mould growth on internal walls. This will normally for as black mould. It is the warm moist air internally settling on the colder internal walls.

Lime Pointing

The Lime Pointing on this period building will allow any moisture in the building to escape. More people now are aware of the advantages of using Lime Mortar. Rising Damp is often related to old period traditional building, but Rising Damp can often be overcome with the use of Lime Mortar. Many of the Traditional buildings in Manchester are built from stone using Lime Mortar, these buildings need to be repaired with Lime Mortar too.

With the moisture content in this wall it would take about 1 year to full dry out.

Lime Pointing Stonework in Manchester Here one of our Restoration Team is using a Hydraulic Lime Pointing Mortar on the rear elevation. Our Specialist team of Restoration Contractors working on this Heritage project in Manchester used a NHL Hydraulic lime mortar for the Lime pointing work. The Damp walls have now dried out, damp in old building is normally due to the external stone work being pointed with a cement mortar. Damp in Manchester requires a Specialist to diagnose the problems related to Damp problems. Damp problems can cause internal plasterwork to "blow" and salts from the gypsum plaster to be deposited on the internal plaster face. Now that the external stone walls have been lime pointed the dampness in the old building will dry out.
Lime Mortar Pointing This area of Lime Pointing had been done the day before this photo. Our restoration team have to finish the lime pointing with a brush.

Most Restoration Contractors use a brush to finish the lime mortar pointing. On this photo you can see the lime pointing our Specialist Contractors have applied to this stone wall. The Lime Pointing is left slightly proud of the stonework, this enables the lime pointing to be brushed back. This will then leave the lime pointing level with the stone wall.

Lime Pointing old house in Manchester Lime Pointing nearly complete. Our Building Contractors working on this project in Manchester worked hard to complete the works within the time allowed. Lime mortar pointing is not a job that can be rushed. When lime mortar is used on old building this enables the Manchester buildings to breathe. We did not install any Helical or Helifix Stainless Steel reinforcing bars to this project as the stone masonry was tied together by re-building section of the wall. Re-building stonework is far better than installing Helical tie bars. It will give a much stronger building. We also undertook Lime Plastering to the internal of the building. The ground floor wall had suffered from damp issues and with the new Lime Plaster the Damp problems were solved. The Lime Plaster was applied in 3 coats, 1 base coat of lime plaster 1 float coat of lime plaster and then top coat lime plaster.
