Baseboard size

I just laid a new vinyl plank floor in the basement. Existing doors have 3/8 thick casing.

The old baseboards were 3/8 thick. Some of the spacing for the new floor is a little more than 3/8.

For the new baseboards can I use a 5/8 thick baseboard? Is there a good way to blend it in with the existing casing? Or is it better to get new 3/8 baseboards and quarter round?

You can either get new door casing that would match the thicker baseboard or get a quarter round. Or just go with a thicker baseboard. It's all about preference. I prefer a seem less look where all trim intersect at similar depths.

If you go with 5/8s then cut it on a 22 degree angle so that it lines up with your casing. If you doing 3/8s i wouldnt use quarter round as it is out of style. Use shoe mold.

Shave the wood part way through so it meets flush with casing.

Hi Mark

There are basically two things you could do.

depending on the style ( colonial ? ) of your existing baseboard. If your able to add a "pre

- painted" shoe mould. This would solve your problem. When you come up to the casings just cut it back at 22 or 30 degree angle, you'll just have to touch up the cut end with paint.

If you don't want shoe mould , go with the thicker base and do the same when you come up to the casings. On this part, you should leave 3/8 of the end still flat and then cut back the facing 1/4"

Thanks for all the help. Didn't want to use qtr round. I'll decide between shoe moulding or using 5/8's and cut at the angle.

First of all spacing in any floating type of floor should be 1/4" to max 3/8" but anyway happen what happen.I think using quarter round does not look professional but that is just me.If you can not move the whole row of planks to adjust spacing?

there are tools to do that.But if you want use thicker baseboard you can beveled high point just by casing and paint it.However I would try to adjust spacing- even remove short pieces and replace by longer ones.

The best way to blend is to use the same thickness of baseboard and add a shoe molding or quarter round molding on both the new and old sections of baseboard. This will serve the double purpose of covering new edges on the newly laid flooring and making it look uniform throughout.

Hope this helps. Good luck and happy renovating!!

Hi Mark

You can look at adding a backband to your door casings that will bring it out to meet the 5/8 and instead of quarter round use the shoe mold trim as it gives a clean look.

You can go online and look at Brenlo supply or Central Fairbank lumber or Trim depot. These are all good resources to help you decide.

Have fun

I would recommend using a 5/8 baseboard and when it meets the 3/8 casing back cut it around 20 degrees or so. This would be the easiest and less money for your solution to your issue. If money is not a big issue I would replace the casings only if they are older and out of date. Another trick would be to add a 5/8 or 3/4 inch smaller trim piece all around the existing casings so that it's equal or the casings a little bigger. Hope this helps you

I would recommend using a 5/8 baseboard and cut 20 degrees when it meets the casing, big baseboard will make your floor looks bigger.

Also you should using quarter around to make baseboard look stronger, nicer and modeler

You have to paint baseboard after install because it comes with primer only.
