• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

Cutting a side door into garage?

Hi all,

I'm after some advice on cutting a door opening into a single brick wall in the garage. It's a very standard build garage, large 440 x 320 brick pillars in the corners of the garage and a smaller 440 x 200mm pillar in the middle of the wall running front to back. It'd be nice to have a side door as illustrated below. My question is, I just need building regs to check it? Should the process be to put in props above, cut out and fit lintel, fit door. Fairly straight forward?



TIA!
 
Forget building regs, just do what you suggest and that should be fine.

You might not need the props. Use a disc cutter to cut out a slot of the lintel. DONT belt it with bolster and hammers. Use a masonry drill though the vertical mortar joints to get the bricks loose Allow 150mm min at each end for the lintel to bear on. Cut out the course below just to the width of the door frame. this should give you working space to insert the lintel, mortar it in etc.

In the very unlikely event that the bricks above the door way start loosening, you can build them up again once the lintel is in place.
Once the lintel is in place, temp fix on a batten to act as a guide for the disc cutter and cut out the rest of the doorway.
Fit door lining etc etc

Thanks Bob, good to know it is straight forward. Don't think my grinder has enough depth for cutting right through so thought I'd hire sawsall as they seem to be pretty good. Also heard of people using reciprocating saws.
 
Yes I'd go for a disc cutter and if you are hiring one go for a dust suppressed one - if not be prepared for lots of it.
Face mask is an essential.

Years ago I made a plastic sheet "tent" to confine the dust and nearly choked to death on the dust kicked out!

I use a reciprocating saw with a masonry blade if the mortar isn't rock hard you get a lot less dust from it compared to a grinder.
Personally I'd install the lintel first, I'd then cut out the bricks with the saw leaving a toothed edge of bricks on both sides of the opening, I'd then build 9" pillars on both sides of the opening inside the garage interlocking the bricks into the toothed out brickwork.
You can reuse the bricks that have been removed for the pillars, doing this will give far more strength than just fitting a door to a single brick wall, it will also give greater security
