A custom glass project touches multiple trades. Frameless shower enclosures, interior glass walls, storefront glass, and custom mirror installations all depend on work that happens before we arrive on site. When coordination breaks down between a glass contractor, a builder, and a designer, the results show up in delays, poor fit, and added cost. At Tim’s Glass & Mirror, we work closely with homeowners, builders, and designers throughout every project. Asking the right questions before work begins makes the difference between a smooth installation and a frustrating one.
Glass installation depends on finished surfaces. Tile must be set. Walls must be complete. Openings must be framed to final dimensions. When these conditions are not met before a glass contractor arrives, measurements are wrong and fabricated glass does not fit.
Early planning directly affects cost. Changes to glass layout or hardware selection after fabrication begins cost more than changes made on paper. Custom glass is cut to exact dimensions. It cannot be returned or resized once fabricated.
For homeowners in Arlington Heights managing bathroom renovations or commercial fit‑outs downtown, getting the sequencing right from the start protects both the timeline and the budget. Ask your glass contractor early what conditions need to be in place before they can measure.
Unclear scope creates problems. Before any glass fabrication begins, get clear answers on these points:
Get every design decision in writing before fabrication starts.
We measure after tile and finishes are complete. Every time. Custom glass is fabricated to exact field measurements. Measuring before surfaces are finished introduces error.
A wall that reads plumb before tile is set may read differently after. A shower curb that looks level during framing may slope after the floor is poured. These differences are small on a ruler and significant on a piece of custom‑cut glass.
Rushing measurements to keep a project moving is one of the most common and costly mistakes in custom glass projects. A door that does not fit correctly cannot be shimmed or adjusted into place. It needs to be remade. Waiting for final conditions before measuring protects your investment and keeps the project on track.
Glass installation sits near the end of most construction sequences. What happens before we arrive determines what we can do when we get there.
Three coordination points matter most:
A glass contractor with a collaborative mindset will flag these issues before they become problems. Ask your glass shop how they communicate with other trades during a project.
A detailed quote protects you. Before approving any glass project, confirm what the quote includes and what it does not.
Ask about:
A quote that does not address these points will likely change before the job is done.
Most problems in custom glass projects are preventable. Watch out for these:
Preventable problems are the most frustrating kind. Ask the hard questions early.

Our team communicates clearly at every stage, from design consultation through final installation. We coordinate with other trades, flag site conditions early, and measure only when surfaces are ready. Contact us to schedule a consultation and get guidance on layout, timing, and installation before your project begins.
Why does a glass contractor need to measure after tile is complete?
Custom glass is fabricated to exact field dimensions and cannot be resized after cutting. Measuring before tile and finishes are complete introduces errors that result in glass that does not fit correctly.
What should a custom glass quote include?
A complete quote covers materials, glass type, hardware, fabrication, delivery, and installation. Any site-specific conditions that could affect labor cost should be addressed in the quote before you approve it.
What glass types are used in custom residential and commercial projects?
Tempered glass and laminated glass are the two most common types. Tempered glass is used in shower enclosures and glass doors. Laminated glass is used where additional safety, noise reduction, or UV protection is needed.
How do I know if a glass contractor is reputable?
Look for written warranty terms, proof of liability insurance, and a clear process for handling post-installation issues. References from past projects and standing with organizations like the Better Business Bureau are good indicators of consistent quality of work.
