High quality brickwork repairs and authentic air vents

October 28, 2012

The brick corner after repairs

The back of my house has been neglected for many years. My recent restoration projects have focused on the large more complex work such as the windows and roof coverings.

My latest project has been the cast iron soil and vent pipe and since some bricks were damaged during its installation, I thought it might be a good idea to get a really good brick restoration specialist in for a couple of days.

I was made aware of a company called Mathias Restoration who undertook brickwork repairs to some very good quality and high value property in North London. Lynn Mathias came down with a young colleague and started work. To say I was impressed was an understatement. Their work was exceptional and of the highest quality.

They started worked on areas that had either become worn or weathered or had been damaged by drill holes or opened up for ventilation purposes. The after works photo speaks for itself.

However, one problem with getting the bricks repaired by Mathias Restoration is that it makes other areas of brickwork look shabby! I’m sure they’ll be back in the New Year for some more repair work.

Choosing air vents…

Having started to look at the brickwork on my house, I’ve also started thinking about the air vents used for sub-floor ventilation. Most of the air vents around the house are the clay brick type which are completely serviceable but not authentic.

As a bit of background, the air vents are used to remove water vapour under the suspended timber ground floors. The through ventilation created by having air vents at the front and rear of the house allow moisture from the ground under the house to escape. If the timber floor joists have a moisture content above 18%, wood boring insects become active and if the moisture content rises above 20%, timber decay becomes an issue.

Now fortunately, I’ve still got two original cast iron air vents on the house, so the other night I did a bit of digging on the internet for suppliers.

To my great surprise I came across the Cast Iron Air Brick Company and to my even greater surprise found exactly the right match. Although they’re more expensive than the standard air bricks, for the restoration junky who can’t compromise, they’re a must have accessory to a fully restored brick wall.
