Whatcom County Flooring for Older Bellingham Homes

Pull up the carpet in an older house in Bellingham, WA and you rarely find just one floor. In the Lettered Streets, Columbia or South Hill you might find original fir boards, a layer of sheet vinyl from decades ago, a plywood patch from a long-forgotten repair and, in the kitchen, something nobody can identify. Whatcom County flooring projects in houses like these succeed or fail on what happens before the new floor arrives.

This guide is for the owner of an older home on joists and a crawlspace, trying to decide what to put down and what to do with what is already there.

First, find out what you have

Lift a floor register or pull a threshold and look at the edge of the floor. You are looking for:

• The layers. Count them. Each one adds height, and height affects door clearance, transitions and stairs.
• The subfloor type. Older houses often have straight or diagonal board subfloors rather than plywood sheets. Boards can move and cup independently, which matters for thin floors.
• Old sheet flooring and adhesive. Older vinyl and the adhesive under it can contain asbestos. Do not sand, scrape or break it up until it has been tested. Covering it is often an option; disturbing it without knowing is not.
• Original fir or hardwood. If you find old fir boards in decent condition, they may be worth refinishing rather than covering.

Keep the fir or cover it

Old fir floors are softer than oak and they dent, but they have a colour and grain that is hard to find new. If they are sound and have enough thickness left to sand, refinishing is often the right call for living rooms and bedrooms.

Cover them when they are badly damaged, when they have been patched with mismatched boards, or in rooms that get wet. A kitchen or entry is a poor place for a soft fir floor through a Bellingham winter.

Whatcom County flooring over board subfloors

If you are covering old boards, the new product has to cope with a subfloor that is less flat and less stable than modern plywood.

Rigid-core waterproof vinyl is forgiving. It bridges small gaps and minor unevenness better than flexible vinyl, which telegraphs every board edge. Ask us which CALI vinyl lines are rigid-core.

Engineered hardwood works well on a flat, sound board subfloor and suits the character of an older house. Its cross-layered core makes it more stable than solid hardwood through the swing between damp winters and drier summers.

Porcelain tile needs the stiffest base of all. Over old boards, that usually means adding a layer of plywood or a suitable tile underlayment and checking that the joists are stiff enough to prevent cracked tile and grout. Your installer should check the floor for bounce before you commit to tile in an upstairs bathroom of an old house.

Laminate needs a flat base and is sensitive to moisture from below. Over a crawlspace, it is the option to be most careful with.

Often the best answer is to add a new layer of plywood over the old boards, screwed down properly. It gives any product a flat, predictable base, at the cost of some height.

The crawlspace matters

A crawlspace that is damp, poorly vented or missing a ground cover will push moisture up into whatever floor sits above it. In older Bellingham houses near creeks or at the bottom of a slope, this is common. Before a new floor goes in, have someone look at the crawlspace. A vapour barrier on the ground and adequate ventilation do more for your floor than any product feature, and they protect the framing too.

Height and transitions

Every layer you keep adds height. Stack new flooring on old sheet vinyl on old boards and you can end up with doors that drag, a dishwasher that no longer slides out under the counter and a trip edge at the hallway. Measure the finished height before ordering. Sometimes removing one old layer, safely and after testing, solves more problems than it creates.

Older houses also have floors that are simply not level. That is different from not being flat. A floor can slope gently from one side of the house to the other and still take new flooring well, as long as it is flat over short distances. Your installer can tell you which problem you have.

Respecting the house

An older Bellingham house often looks best with materials that suit its age: wood or wood-look floors in the main rooms, a simple tile in the bathroom. A modern grey vinyl can look out of place against original trim and doors. Choose a tone that works with the existing woodwork, especially any fir stair treads or door casings you are keeping.

Bring photos of the layers, the approximate age of the house, a note about the crawlspace and your room measurements. Those four things narrow the choice quickly. Browse our flooring category, see our Bellingham service area page for how to reach us, or call (360) 255-8377 to talk it through.
