The final cost is primarily determined by whether the project is an isolated threshold structural repair or part of a comprehensive master suite remodel. Key pricing factors include the length of the curb, the selected finish materials, such as a seamless quartz slab versus individual porcelain tiles, and the underlying structural requirements. If we discover hidden dry rot in the subfloor joists during demolition, or if your design requires complex modifications like tying the curb into a custom built-in pony wall or frameless glass channel system, the structural scope changes. Levite Construction Co. provides clear, upfront line-item estimates so you can visualize exactly how your budget is put to work.

A standard shower curb modification and pan waterproofing phase generally takes between 5 to 10 working days to execute properly. The initial demolition, structural wood replacement, and framing rough-in require 2 to 3 days. Installing the specialized composite or mortar bed core along with the advanced waterproofing membranes takes another 2 days, which includes the mandatory 24-hour municipal water flood test to verify an absolute seal. Precision stone fabrication, tile setting, grouting, and the mounting of frameless glass track anchors consume the remaining 3 to 5 days. Timelines can expand if structural joist alterations require specialized city inspections, but our dashboard keeps you informed daily.

If you are performing a simple cosmetic replacement of cracked surface tiles on an existing, intact curb without altering the pan or drain, a permit is typically not required. However, if you are tearing down to the structural framing, replacing a leaking pan liner, relocating the drain line, or lowering the joists for a modern curbless transition, you must secure building and plumbing permits. Our dedicated project management team completely handles this administrative phase, drafting code-compliant submittals and coordinating all formal site inspections with the Seattle Department of Construction & Inspections (SDCI) to guarantee compliance.

Yes, you can certainly remain in the home, provided you have access to an operational alternative bathroom. The immediate workspace will be a tightly contained clean-site zone, sealed off with heavy dust barriers to protect your indoor air quality. There will be noticeable demolition noise, structural tool usage, and brief, localized water shut-offs when connecting the new drain assemblies. Because the shower pan must remain completely undisturbed during the multi-day waterproofing cures and mandatory flood testing phases, the primary shower will be completely offline for the duration of the installation phase.

The design-build framework combines structural carpentry, specialized waterproofing, and finish stone masonry under a single point of management. In traditional remodeling, a standalone designer might select a beautiful threshold finish stone without calculating the weight load or checking the framing requirements for heavy frameless glass doors, leading to structural sag or leaks down the road. With Levite Construction Co., our construction crew works alongside the design phase from day one. This guarantees that your curb's internal structure is perfectly engineered to match your finish tiles, prevents expensive communication errors, and ensures a lifetime waterproof seal.

Given the significant atmospheric moisture and seasonal shifting in the Pacific Northwest, avoiding wood framing inside the curb core is a smart strategy. We utilize high-density, pre-fabricated structural composite curb cores or solid reinforced mortar matrices that cannot rot, warp, or expand when exposed to moisture. For the top cap, we strongly recommend a single, solid piece of non-porous engineered quartz or natural stone slab rather than tiled grout joints. This eliminates the vulnerable seam lines directly underneath the shower door sweep where water hits continuously, ensuring a low-maintenance, leak-proof threshold.

Hidden moisture leaks are the most common issue uncovered when tearing down old shower entries in historic Seattle homes. If our team exposes rotted subfloors, structural insect damage, or decaying floor joists caused by a failed legacy pan liner, we pause the structural phase immediately. We document the discovery with clear, high-resolution photography and draft a transparent line-item change order. This document outlines the exact structural lumber, specialized anti-microbial treatments, and labor required to rebuild your floor infrastructure safely according to modern building codes before any new tile finishes are applied.

A standard handyman or low-tier subcontractor will often simply build a curb out of cheap dimensional 2x4 lumber, wrap it in a loose PVC liner, and tile over it. Wood twists naturally over time, and puncturing the liner with glass anchor screws causes slow, hidden subfloor rot that can cost thousands to fix later. Levite Construction Co. brings comprehensive general contracting expertise to the job. We manage the entire process, from structural joist reinforcement and advanced liquid-applied liquid membranes to precision slab fabrication and city permit sign-offs, delivering an architecturally sound threshold built to remain dry for generations.
