DIY seamless flooring transition between a 100 year old house and new extension

How to transition new and old flooring

 

Tips for laying flooring, avoiding a transition

Let me caveat this post by saying we are not flooring specialists, just DIYing our own home.

 

I hate a funky floor transition or a strip telling you this was added. I look at a renovation with rose-coloured glasses; any change you make to a floorplan should look like it was part of the original house. A wierd floor transition is one of those tells.

 

We recently opened up access from the original house to the extension (original house is 1915 Queenslander) The top floor extension will include the bedrooms and bathroom for the kids and access to our master suite. You will access it via a hallway from the original house; I’m currently designing a floor-to-ceiling pocket door so we can close off the bedrooms if desired.

 

I’m so excited to share this post as we have been working sooooo hard behind the scenes; laying flooring in the extension means we are one step closer to finishing the kid’s rooms!

So for the last week or two, Derek and I have been sweating like crazy getting the floor laid in the kid’s rooms and in the hallway. 

 

The trickiest part of the whole project was tying the new floors into the old house. There will always be variation in the wood, you can’t fake 100 year old wood. We bought hoop pine the same size and I have chosen a stain that will help miminise the variation – but that’s a post for another day.

Prepare the floor

We had tiles over our floors, we knew there was wood underneath the tiles, but we had no idea what condition they were in. We spent the better part of a day removing the tiles, which had been installed over concrete boards, allowing us to remove them in sections and save the wood. Once removed and cleaned up we used a pry bar to remove the remaining nails in the floor. And it was beautiful so we did a happy dance and then planned for the next day. 

There was a slight height difference between the original house and the extension, so we needed to build up the floor to level it out, there will be a slight slope, it’s so slight you wouldn’t notice it but if you don’t build it up, then you’d have different heights.

Stagger the original flooring

Using a multi-tool Derek cut into the original wood, on the joist. We need to ensure the new wood and old wood are able to be fixed to the joist so cut at the midpoint.

Clean out the old joins of the wood, there was over 100 years of dirt in ours, and you want the new wood to slide in nicely. It needs to fit tightly but you don’t want to split the wood.

Install new wood

Spread liquid nails evenly along the floor where your piece of flooring will go. Using some offcut to protect the wood we carefully drove the newpiece of flooring into the gap of the old flooring. By holding a piece of offcut to the end of the wood we could hammer the wood inplace without damaging the board. 

One of us hammered the wood into place; The other person guided the wood in place.

Once in place we used a nailer to nail the wood to the floor.

We predrilled holes in the wood where it meets the old wood, you can’t get the flooring nailer into place. We added screws to reduce movement and lifting. These will be filled when the floor is stained.

And that’s it, we repeated this process until the hallway was finished.

 

I know it doesn’t look like much now but once the floor has been sanded the variation in colour will be less obvious. And as we have chosen a darker stain this will help minimise the difference.

Part Two

 

We still need to finish the rest of the hall into the master and the master closet then we will sand and stain.

But before we do any of that we need to finish the trim, fill and paint.

I’ll be sharing an update on this is part two.

 

We have just finished the floors in our sunroom so this will give you an idea of what to expect.

Re: DIY seamless flooring transition between a 100 year old house and new extension

Such a seamless job @Renowayoflife!

 

You should be absolutely proud of the progress you have made so far. That dark stain is going to be so gorgeous throughout your home. For the height difference, how did you build up the floors to match? Also, I'm kind of digging your seafoam green sink, do you think you'll re-use it somewhere? 

 

Can't wait to see the full transformation!

Thank you @KatieC Thank you!

 

I love dark floors and light walls so I am so excited to see it all come together.

 

We used different sized plywood to match the heights we started with 12mm, 2 x 4 for 8mm and 4 mm and 2mm - this created a gradual slope. The distance and amount really depends on your height difference. We opted for a more gradual slope over a longer length so it's barely noticed, if you didn't pack it in then you would definitely notice the difference.

 

Isn't it amazing! I am going to reuse it in the toilet downstairs, it's off the pool. I'm not sure yet if I will re enamel it or leave it.

Hi @Renowayoflife 

 

That dark floor stain looks amazing, and the seamless transition looks great. My vote is to leave the sink in its original finish, unless it totally clashes with your bathroom design downstairs. It's a nice classic design and will provide many more years of service.

Thank you @EricL , I appreciate you saying so. 

 

Th'ts a good point, I haven't designed the downstairs toilet so maybe I will make the sink the feature piece. I'll keep you posted once we get there. We have a whole house to renovate before that toilet.

Re: DIY seamless flooring transition between a 100 year old house and new extension

That sink will make an awesome feature as a poolside toilet @Renowayoflife. It has good vibes about it. 

 

Thank you for sharing your sloping floor solution, a great tip I am sure our members appreciate.
