cracked walls

Horizontal cracking, vertical cracking, angular cracking, crazing, blown render, stone wall, stone house wall, damaged wall, damaged render, render replacement.

I was asked to look at a Portuguese house recently which had suffered with the external walls cracking. The couple were about to buy the property but wanted to make sure that the cracking wasn’t recent and that is was not going to get worse. Obviously they didn’t want to put their hard earned money into a money pit.

 We don’t have a crystal ball so you have to research the property and look for evidence.

Here are a few things we look for. New building close by, land slippage, flooding, property extensions, part demolitions of connected out buildings or adjoining properties. Cellar excavations or new drainage installations.

Then we start to look at the overall structure. How is the property built, with what materials and methods. Is the roof old, is it straight or sagging, what is the condition of the main roof timbers. Do they have splits, cracks or breakages are they suffering from bad woodworm infestation.

Then we look inside the property to see if there are cracks matching those outside on the inside. Is there evidence of rain water entering the cracks and passing to the inside of the property.

Once we have established that there are no obvious and serious external factors causing the cracks we can look at the types of cracks Horizontal cracking, vertical cracking, angular cracking, crazing, blown render, stone wall, stone house wall, damaged wall, damaged render individually.

It is not often appreciated that most old Properties in Portugal do hot have what we would call foundations in northern Europe.

They relied upon building flexible walled houses that would move slightly over time and settle into the ground. Ground frost is not usually a problem here so the houses stay viable for a couple of hundred years.

It takes many years of construction experience and many years of Portuguese building method experience to be able to read property problems.

how long Removing render from stone houses

How long

 How long does it take to remove the cement render from a house wall and re-point between the stones with lime mortar.

Many people ask is it possible to remove the cement render from a house wall and re-point between the stones with lime mortar for a DIY enthusiast.

Cement render on stone house

We are asked these questions a lot. So here are the answers.

It obviously depends on the size of the stone house wall. This one is eight meters wide by 6.5 meters high.

Looking at it from the DIY perspective. Do you have enough scaffolding available to carry out the work safely? Are you confident standing and working on scaffolding at this height?.

Do you have all the tools for the job.  Renting tools in Portugal is very difficult you will need a large SDS hammer drill, scaffolding, chipping hammer, Very high-pressure jet wash (not one that you wash your car with) and re-pointing equipment.

How long? It all depends upon how fit you are as to how long it will take. A reasonable estimate would be 3 times the man hours that it takes us.

Our guys are professionals and work on this type of thing day in day out so they don’t need a lie down in the afternoon. Make no mistake you will hardly be able to raise your arms after the first day if you are doing this for the first time  I don’t care how fit you think you are.

The repetitive and very dusty work really is hard. Dust in your eyes constantly and large amounts of fine dust to breath in.

Cleaned and ready for pointing

How long does it take to remove the cement render from a house wall

We had a team of two people working on this gable it took them two days to take off the old cement render which was on a south facing wall and baked on. The erecting of the scaffolding and high-pressure jet wash took another day. That’s 6 man days or you could say a week’s work for two people to get everything ready for pointing. There was also some stone to be replaced before the pointing.

If my reckoning is correct then it will take a DIYer 12 to 18 days of hard graft to make just the gable wall ready for pointing.

Doors through stone house walls

Doors through stone house walls

You have found the ideal property in Portugal; perhaps it’s a traditional stone built house with lots of character but not much interior light.

It could be for instance that you want to gain access a nice area of the garden without going around the house or your plans for remodeling the interior space require a new entrance door through stone house walls.

How do you do it, can it actually be done, what are the potential problems.

Castelo Construction has been carrying out this type of structural work for many years and with very good results. You can have a normal width door or even patio style doors knocked through your brick or stone walls even if they are over a meter thick.

 

How do you do it?

With a great deal of care and experience. This may sound obvious but taking a section out of the structural walls of a building can be very dangerous because of falling stones and debris. The work is usually done with three people.

Can it actually be done?

Because you are altering the structure of a home it is very important to make sure in advance that it can be achieved. It is not a case of trying a location and seeing what happens next. Our craftsmen understand the stresses and building methods that they have to deal with which requires years of experience.

What are the potential problems?

If the stone walls of house have an uneven amount of stress they can buckle and collapse if a hole is cut in the side of them.

Remember the stones in old houses are only held together with mud. You can experience the effect of cutting a large hole in a house by cutting a hole in a cardboard box.  You will see that it immediately becomes unstable.

Which is why we use our many years of experience a great deal of care and tried a trusted techniques to support the house while the work is being carried out.

It is important to understand how dangerous this kind of work can be. In the UK last year  11% of workers suffered serious injury from falling objects.
