Do you work in Boise's historic districts?

Yes. Interior tile work in the North End and Warm Springs historic districts does not normally trigger historic design review, since review focuses on exterior-visible changes. We still work around original trim, baseboard heights and door clearances rather than through them.

Are permits required for tile work in Boise?

Tile itself is a finish and generally does not require a permit. Permits come into play when a project moves plumbing fixtures, alters framing, or adds an electrical circuit for heated floors. Where that applies we coordinate the permitting with the licensed trades doing that portion of the work.

My 1930s bathroom floor flexes. Can it still be tiled?

Usually, but only after the flex is addressed. That may mean adding a plywood layer, sistering or blocking joists, or in some cases a structural evaluation. Tiling over a floor that moves guarantees cracked grout within a year or two.

Boise is the most varied tile market in the Treasure Valley because the housing spans more than a century. A 1920s North End bungalow and a 2019 Harris Ranch build present opposite problems, and the prep that makes one floor last will be wrong for the other.

That is the whole reason we quote after looking at the substrate rather than off a square-foot number over the phone.

What we find under Boise floors

Pre-war bungalows: plank subfloors and deflection

North End, East End and Warm Springs homes from roughly 1910 to 1940 typically sit on dimensional fir joists with diagonal plank subfloors. Planks move independently and gap seasonally, so they get sheathed over and flattened before tile, and the joist span often needs checking against the L/360 deflection limit tile requires. These are also the houses where a bathroom floor has been rebuilt once or twice already, so what is under the vinyl is genuinely unknown until it is open.

Bench and Southeast ranches: slab and post-tension considerations

Mid-century ranches across the Bench and parts of Southeast Boise are frequently slab-on-grade. Slabs bring their own checklist: moisture testing before anything moisture-sensitive goes down, evaluating existing shrinkage cracks for crack-isolation membrane, and grinding off decades of old adhesive. Control joints in the slab must be honored through the tile as movement joints rather than grouted over.

Foothills and newer subdivisions: flat but not flat enough

Newer builds in the Foothills, Harris Ranch and Southeast Boise usually have engineered joists and OSB sheathing — predictable, but built to framing tolerance, not tile tolerance. For 12x24 and larger tile that gap between the two is what self-leveling underlayment closes.

Dry climate, big indoor humidity swing

Boise's high desert climate takes indoor relative humidity from very dry in winter to substantially higher in summer. Wood framing moves with it. That seasonal movement is exactly what uncoupling membrane over a wood subfloor is designed to absorb, and it is why we do not set tile directly to plywood.

What Boise homeowners ask us for most

Tile shower installation
Older Boise bathrooms are the most common shower rebuilds we see, usually because a mud pan or an early liner has reached the end of its life.
Tile floor installation
Entries, kitchens and mudrooms, where prep varies enormously between a plank subfloor downtown and a slab on the Bench.
Heated tile floors
Frequently added to bathroom remodels in older homes that have cold uninsulated crawlspaces underneath.
