Should I remove baseboards before flooring installation in my NB home?

Yes, removing baseboards before flooring installation is the recommended approach for a clean, professional result in most NB homes. While it is possible to leave baseboards in place and cover the expansion gap with quarter-round or shoe moulding afterward, removing them first gives you a much better finished look and avoids the layered appearance that quarter-round creates.

When you remove baseboards before installation, you gain two important advantages. First, you can run the flooring right up to the wall framing (leaving the required 8-12mm expansion gap hidden behind the baseboard when it goes back on), which eliminates the need for additional trim pieces. Second, you get the chance to inspect the bottom of your walls for moisture damage, mould, or air leaks — something that matters in older NB homes where Maritime humidity can cause hidden problems behind trim.

To remove baseboards without damaging them, score the paint line along the top edge with a utility knife first, then use a thin pry bar and a putty knife behind it to protect the drywall. Number each piece on the back with a pencil so you know exactly where it goes when you reinstall. In many pre-1970s NB homes, baseboards may be painted or caulked heavily after decades of repainting — take your time and expect some touch-up work afterward.

If your baseboards are in poor condition or you are planning to replace them anyway, removal is a no-brainer. New baseboards installed over fresh flooring give the sharpest finished look. Budget $2-$4 per linear foot for new MDF or pine baseboards plus paint, or $4-$8 per linear foot for stained hardwood baseboard that matches your new floor.

If you choose to leave baseboards in place, you will need to install quarter-round or shoe moulding along the bottom edge to cover the expansion gap between the flooring and the baseboard. This is a perfectly acceptable approach and saves labour, but it does change the trim profile of the room. Quarter-round runs about $1-$2 per linear foot for materials. The key concern in NB is making sure the expansion gap behind the quarter-round is still a full 8-12mm — our Maritime humidity swings from winter lows of 20-30% to summer highs above 60% cause more expansion and contraction than most inland provinces, so undersized gaps lead to buckling during humid summer months.

For tile installations, baseboards should always come off because tile requires a rigid, precise edge that cannot be hidden with quarter-round. For floating floors like laminate, LVP, or engineered hardwood, either approach works, but removal produces the better result.

If you are hiring a professional installer, discuss baseboard removal upfront — some installers include it in their quote, while others charge $2-$4 per linear foot extra for removal and reinstallation. Getting this sorted before work begins avoids surprises on installation day.
