Browse Forums Renovation + Home Improvement 1 Jan 16, 2014 9:54 pm Hi All, I am looking at converting my two door garage into a single door. Below is the breakdown of the work i have been provided in a quote. All up for 7.2k. Removal of existing garage doors Removal of existing beam and cornice Removal of brickwork Supply and fit new hardwood beam Supply and fit new cornice Supply and fit new eaves sheet Supply and fit new panelift door in Classic Cream with operating motor. Given that this is my first quote, not sure if this amount is way too much. Appreciate your feedback. thanks John Re: Converting two door garage to single door 3Jan 17, 2014 7:15 am Quote: I can't see why you need new eave sheets and cornice. Just the front I'd say because the central brick pier would jut out into the eaves leaving a hole when you remove it. The guy has quoted hardwood because it is probably easier to use ( fixing to etc ) as long as it will span the distance OK Stewie Re: Converting two door garage to single door 6Jan 18, 2014 7:32 am Please find attached some images http://postimg.org/image/n6uygnkz9/ http://postimg.org/image/l3kj8zl6d/ http://s26.postimg.org/pqqlar8jd/Garage8.jpg Re: Converting two door garage to single door 7Jan 18, 2014 7:34 am [quote="JB1"]Can you post a.photo. Some photos can be found here.. thanks http://postimg.org/image/n6uygnkz9/ http://postimg.org/image/l3kj8zl6d/ http://s26.postimg.org/pqqlar8jd/Garage8.jpg Re: Converting two door garage to single door 8Jan 18, 2014 11:59 am As I thought but it is going to have to be a pretty substantial hardwood beam to support that tiled roof. I'd lean towards JB1's suggestion of a steel beam even though being a carpenter by trade my preference would have been to work with timber as well. Stewie Re: Converting two door garage to single door 9Jan 18, 2014 6:06 pm I think a hardwood beam is doable, but if Stewie, a carpenter said he would use a steel beam, I'd listen carefully. If the hardwood beam design has been approved by an engineer, then it should be suitable. But if it hasn't been professionally engineered calculating the loads, a steel beam gives much more room for error. What is interesting about the photo for me is- from outside the area above left and right garage door is identical but from inside is different. Re: Converting two door garage to single door 10Jan 18, 2014 7:53 pm Thanks JB1. Would you suggest i ask the builder if the the proposed used of a timber beam has been approved by an engineer in terms of the design and the load bearing capacity? thanks Re: Converting two door garage to single door 11Jan 18, 2014 8:35 pm JB1 I think a hardwood beam is doable, but if Stewie, a carpenter said he would use a steel beam, I'd listen carefully.

What is interesting about the photo for me is- from outside the area above left and right garage door is identical but from inside is different. It is just the photo that gives this illusion. When he photo is taken on the inside you will notice the door is tilted open blocking the view of the beam. A steel beam doesn't give room for error if it is also undersized Re: Converting two door garage to single door 12Jan 18, 2014 8:45 pm johndural Thanks JB1. Would you suggest i ask the builder if the the proposed used of a timber beam has been approved by an engineer in terms of the design and the load bearing capacity? thanks It would provide piece of mind I suppose to get an engineers stamp, but timber beams don't need such a signature as he will only reference span tables already written in the 1684 or supplier documents. I would suggest a laminated timber beam. If you want proof of its suitability just ask for the supplier documents. You should be able to tell by speaking to your builder if he is switched on or whether he is guessing it. Without knowing the exact specs of your job, the size of the beam should be around 300 x 65. Steel isn't very friendly above a garage door as the door installer needs to mount brackets to it, and then there is the open face of the channel that needs packing out on the eaves side. Eaves will need to come out because the frame work will be nailed to the existing beam, and it will also ease installation. It sounds like a fair description of the work to be carried out, where are you located?

So from what you are saying laminated timber beam would do. Note that end to end the span of the garage opening after the pier is removed will around 4400 mm. Do you see any issues with a timber beam supporting this wise span? i am located in Dural, NSW. Re: Converting two door garage to single door 15Jan 20, 2014 8:27 pm Hi all.. here is a breakdown i have been provided. Keen to hear your feedback. I am asked the builder to come back to me with the costs associated with a steel beam. The below quote is for a timber beam... Demolition - doors $ 200.00 - beam and cornice $ 358.00 - eaves sheet and trim $57.00 - brickwork $ 58.50 Subtotal for Demolition: $ 673.50 ------------------------------------------------------------------------------- Rubbish removal $ 523.00 ------------------------------------------------------------------------------- B&D Panelift door with motor $ 3,845.00 ------------------------------------------------------------------------------- Carpentry - Hardwood beams 2/240*45 – $ 1,225.00 - Cornice $ 126.55 - Eaves sheeting $ 148.00 - Trim $ 75.00 Subtotal for Carpentry: 1,574.55 ------------------------------------------------------------------------------- G.S.T [10% ] : 661.60 Total including G.S.T : 7,277.66 Total: 6,616.05 Re: Converting two door garage to single door 16Jan 20, 2014 9:54 pm Yeah, No probs getting a timber beam to do the job. Would be cheaper than a steel beam because there would be extra brackets of some sort because you cant just nail the steel back to the existing roof trusses etc. Steel will just cause too many headaches. And getting him to provide a quote on a steel beam which you wont go with is just wasting his time. 4400 is actually a small garage opening. Drive around a new housing estate and you will see new frames being built with timber garage beams Re: Converting two door garage to single door 17Jan 23, 2014 7:46 pm 33amc 4400 is actually a small garage opening. Drive around a new housing estate and you will see new frames being built with timber garage beams just checked and its a 5400 opening instead Re: Converting two door garage to single door 18Jan 24, 2014 9:46 pm 5400 opening? From my calculation 2/240x45's wont span that, and that's even if we say there isn't any girder point loads on it (which there more than likely is) I cant make all the specifics out from the photo, but even if I run a best case scenario its a fair way off. I would question this.....

As per what 33amc said before 300 x 65 F17 is probably the minimum and to be safe I'd look at either one 300 x 75 or two 300 x 50's nailed together. If in doubt we used to step up to the next bigger size just to be on the safe side whereas a lot of guys will just go for the minimum with long term consequences. The 300 x 75 will set you back $55 /m. Two 300 x 50's would work out to $64/m A 200UB22 would easily carry that load over that span and is $62/m. True there is a bit more work in attaching brackets etc but we've never had much of a problem doing this in the past. The best thing I like about steel is that it doesn't warp bow or twist nor does it creep under load with minimal long term deflection. Stewie Re: Converting two door garage to single door 20Jan 25, 2014 10:06 pm Hi Stewie, I was referring to a 17c or 18c beam not a run of the mill hardwood beam. A 17c is around $65/m. They are also cambered allowing for deflection. I doubt any timber other than engineered timber would span efficiently. A UB Would be a pain to work with. If you desperately were a steel fan than I would be looking at a PFC. Also, don't forget that with the steel you will need steel posts either side for mounting as well as the cost for fabricating with all the holes or tabs needed for connecting it to the timber roof structure. Plus timber would be about half the weight which reduces the need for a mechanical lift or an extra couple of hands. I cant see a steel beam being cheaper or more user friendly. Even if the timber beam cost $20/m more (like for an 18c) this only $120. It wold cost more than $120 for 2 steel posts Just my thoughts, but the bottom line is the specified beam is well under done Andrew If I hire a contractor to convert a window to a sliding door will I need to show them Council approval paperwork?
