Tile Floors in Older Bellingham, WA Homes Over a Crawlspace

A lot of the tile we talk through goes into houses that were built long before anyone expected a porcelain floor in the bathroom. If you are shopping for tile in Bellingham, WA and your house sits on joists over a crawlspace, the floor structure matters as much as the tile you pick. Tile is rigid. Wood framing flexes. When the two disagree, grout cracks first and tiles crack next.

This is not a reason to avoid tile in an older house. It is a reason to ask a few questions before you fall for a particular product.

Why older framed floors are different

Many houses in Columbia, Sehome, the Lettered Streets and South Hill have original joists, board or plank subfloors, and decades of settling. A floor like that can feel perfectly solid to walk on and still deflect enough under load to crack a stiff tile over time.

Common problems your installer will look for:

• Joists that are undersized for their span by modern standards, or that were notched for old plumbing.
• Plank subflooring with gaps between boards, which is not a suitable base for tile on its own.
• Old vinyl or sheet goods that need to come up before anything goes down.
• A floor that is out of level or out of flat, especially near an old exterior wall.

A crawlspace that stays damp through the wet season adds another variable. Moisture from below can keep framing moving seasonally. Getting the crawlspace dry and ventilated is a house problem, not a tile problem, but it affects how the tile performs.

Choosing tile in Bellingham, WA for a floor that moves

Once the structure has been checked and stiffened where needed, the tile choice still matters. Some materials tolerate a little movement better than others.

• Porcelain over natural stone. Natural stone, especially marble, needs a stiffer floor than porcelain does. If your floor is borderline, porcelain is the safer pick.
• Moderate formats over very large ones. Large-format tile needs a very flat substrate and shows every dip as lippage. On an old floor, mid-sized tile or a mosaic is often more forgiving.
• Mosaics for small, uneven rooms. A hexagon or small square mosaic on a sheet follows minor undulations better than a big tile does, and the many grout joints add slip resistance. We carry around a hundred hexagon mosaics, which suits the classic look of an older bathroom.
• Cement tile with care. Cement tile looks right at home in a period house, but it is thick, heavy and wants a solid, flat base.

What goes between the joists and the tile

Your installer decides the assembly, but it helps to know the vocabulary so you can follow the conversation:

1. Structural repairs: sistering or blocking joists, fixing notches.
2. A proper plywood subfloor, sometimes with an added layer.
3. An underlayment such as cement board or an uncoupling membrane, which helps separate the tile from small movements in the wood.
4. The tile, set in the thinset your installer specifies, with movement joints at the perimeter.

Skipping perimeter movement joints is a classic cause of tented or cracked floors. Tile needs a little room at the walls, hidden under the baseboard or finished with a flexible sealant.

Matching the style of an older house

Period houses often look best with tile that respects their age. A few directions that work well:

• Small white or black-and-white hexagon mosaics in a bathroom.
• Encaustic-style patterns in a kitchen or entry, either real cement tile or a porcelain version.
• Warm terracotta tones or muted greens in a Craftsman bungalow.
• Simple, matte porcelain in a neutral stone look where you want the woodwork to lead.

Questions to answer before you order

• Has someone actually looked at the joists and subfloor from the crawlspace?
• Will the finished floor height work with the adjacent rooms and doors?
• Is the tile rated for floors, and is the finish suitable for a bathroom that gets wet?
• Does your installer have a preference for format given the condition of the floor?

If you can answer those, choosing the tile itself becomes the easy part. Call (360) 255-8377 or email [email protected] with a photo of the room and a note on the floor structure, and we will help you narrow down tile for your Bellingham house that suits both the look and the framing underneath it.
