I am extending our hallway using some laundry space, and there is a chunk of chipboard in part of it so I have to buy some timber floorboards to continue the wooden floor from the existing hallway.

 

I don't know what the timber is, but guess it's Matai or Rimu.  We have recently taken a wall out, and the timber from that has very red sawdust.

It looks like polished Rimu to me.

A Timber Yard will be able to identify that easily

What age is the house? Tawa was another common flooring timber.

Red sawdust is often a good sign of matai, but be aware different timber was often used for floors and walls so it's not conclusive.

Don't believe a word I say, not an expert or anything, but my instinct would be totara. Your pictures have the same grain but different colous. While this could be due to the finish, totara heartwood and sapwood are different colours.

Where are you? If Wellington, City Timber on Thorndon Quay will sort you out. Ideally take a sample with you, but other wise they will probably let you take some samples away to compare to the original.

Agreed - and "heart" rimu.

 

It may not be easy to get a match to either the timber or the profile, as well as there being variation from supplier to supplier in overall thickness and width back when this was commonly used, the tongues and grooves may be different depths and thickness and position relative to the timber face, which may be an issue if you're wanting to extend or patch a continuous floor area without it looking patched.  Best bet may be to cut a small piece of an end of one of the existing boards and take it with you around recycled timber yards.  I removed a fireplace at our place with similar floors, and needed to patch the hole in the floor where the concrete base had been,  Searching through the racks at the timber yard (Musgroves Chch) I eventually found some with the same t&g profile, but still needed to run it through a thicknesser. It was quite a lot of faffing around to get it right. I could have had the profile made with new timber, but new heart rimu even if available would have cost a fortune, plus there'd have been a fixed set-up cost for the supplier to do a run of that profile.  With luck you may find some recycled timber of the same profile, but also where the joist spacing where it came from was the same, so that most of the nail holes may be reusable.

 

 

 

Edit to add, that when you do get the timber, then consider whether to cut back some of the existing boards to the next joist back, to "stagger" where the new boards are fitted so that you disguise the join.  This may require some extra faffing around and removal of some sections of tongues on boards in order to get them to slot in.  If the chipboard is there because some flooring had to be cut out to gaiun sub-floor access at some time in the past, and that might be needed again, then another idea may be to make a proper trap door with hinges and recessed brass ring handle etc.  In some ways that might be easier than trying to patch it, and the result might look like it was always there and a feature rather than a flaw.

Great, I work on Thorndon Quay and will head down there later in the day. Some shelving we pulled out were made of leftover floorboards

+1 for rimu - heart rimu also makes red sawdust.

The guy @ City Timber took about 3 seconds to tell me it was Matai (had the samples with me) and he has brand new stuff in stock.

 

 

 

 

 

The framing may well have been Rimu. Now Ill be trying my hand at making some chopping boards / pot stands out of the recycled timber.

Plenty of us wrong about that then - but I'm sure he's right.  

 

You've even got me wondering now if my floors are matai - not rimu  - but I don't think so.  Grain, colour etc on your first photo looks just like our floors.

Is there any way you can lift the carpet in a bedroom take out some floorboards, replace with the new ones and use the old 'matching' ones in the hallway?

Not sure whether to pat myself on the back for the City Timber recommendation or hang my head in shame at the wood guess.

Seriously tempted at 1984-ing my post and claim I was right all along though.

I don't want to muck  about with pulling T&G floorboards up and potentally breaking them. Plus one of the bedroms has a different proilfe (135mm wide vs 85mm - was added a few yeasrs later)

A lot of the colour you have in the boards will be from the coating that was applied at the time, combined with years of exposure to daylight. Any boards taken from underneath carpets will still look brand new in comparison. 

 

I've just been through the process of sanding and polyurethaning our bathrooms heart rimu floors... it's not a very nice job to do and can highly recommend just paying someone to do it if you are even the faintest bit unsure about the process. You will probably want to sand some of the older boards at least to help fade the new boards into the existing. You may also want to look at tinting of the coating. tl;dr talk to a timber flooring expert before you consider attempting this on your own. If that was something you had thought about.

Apparently we have really nice timber floors in our lounge, but the house was carpeted a few years ago before we bought, so I'm loathe to pull any of it up to have a look...... wife loves timber flooring but we dont want to risk pulling up the "new" carpet to find pine/bickyboard ;)
