Why Choose a Professional Tile Contractor vs. DIY or Handyman
Key Takeaways
- Improper tile installation is the leading cause of tile failure in residential settings — and most failures trace back to subfloor prep, waterproofing, or inadequate technique
- Professional tile contractors bring specialized tools, materials, knowledge, and installation experience that produce floors lasting 20 to 30 years
- DIY tile installation is possible in simple, low-moisture applications but carries real risk in bathrooms, particularly in shower enclosures where waterproofing is critical
- Handymen who do tile occasionally are not the same as dedicated flooring installers who do it daily
- Leicester Flooring’s installers have worked with the company for years, back every job with a lifetime workmanship warranty, and treat your home with genuine care
When a bathroom renovation comes up, the question of who should do the tile work comes up right alongside it. YouTube makes it look achievable. A neighbor recommends a handyman who does everything. And the professional tile contractor option feels like the most expensive path.
Here’s the honest picture: tile installation done correctly lasts 20 to 30 years. Tile installation done poorly fails in 3 to 5 — and when bathroom tile fails, the damage behind it is often worse than the tile itself. The decision about who installs your tile is really a decision about how long you want to be doing this again.
This guide covers what actually separates professional tile installation from DIY and handyman work, where each option makes sense, and what to look for when you decide to hire.
What Can Go Wrong with Tile Installation
Understanding the failure points in tile installation makes the case for professional work more concretely than any general argument about expertise.
Subfloor Preparation
Tile is rigid. The surface it’s bonded to has to be equally rigid and flat. Any flex in the subfloor transfers stress to the tile and grout. Over time, that stress cracks grout joints first, then can loosen or crack tiles themselves.
The standard in professional tile installation is that the subfloor must deflect no more than L/360 (length of span in inches divided by 360) under load before tile is installed. Achieving that standard in older homes with wood subfloor construction often requires additional substrate support, cement backer board, or both.
DIY installers and generalist handymen frequently skip or underestimate the subfloor assessment. Professional tile contractors — particularly those who’ve done it for decades in WNC homes — check for this specifically because they’ve seen what happens when it’s ignored.
Waterproofing in Wet Areas
A properly installed shower tile assembly is waterproof at the tile surface. The cement backer board behind it is moisture-resistant but not waterproof. The waterproofing membrane applied over the backer board is what actually prevents water from getting into the wall cavity.
Skipping or improperly applying the waterproofing membrane is one of the most consequential mistakes in bathroom tile installation. Water that gets behind the tile doesn’t cause immediate problems. It sits. It promotes mold growth. It degrades wall materials slowly. Homeowners often don’t discover the damage until they’re looking at a full shower gut and rebuild — a $5,000 to $15,000 repair that a properly installed shower would have prevented entirely.
According to the National Tile Contractors Association, improper waterproofing is among the leading causes of costly bathroom renovation failures.
Tile Layout and Pattern Planning
Tile layout isn’t just about aesthetics — it’s about minimizing waste, ensuring cuts at walls are balanced, and making sure the most visible areas of the room have whole tiles or nearly-whole tiles rather than slivers.
Professional tile setters lay out tile dry before any mortar is applied. They identify where the cut lines fall, adjust the starting point as needed, and plan around obstacles like drains, thresholds, and fixture penetrations. Skipping this step produces a finished floor where the last row at the wall is a quarter tile next to the door — a sign of amateur installation that’s impossible to miss once you notice it.
Proper Adhesive and Grout Selection
Not all thin-set mortar is appropriate for all tile types and applications. Large-format tile requires a larger-notch trowel and a modified mortar to achieve back-butter coverage above 80%. Porcelain tile requires a mortar formulated for low-absorption surfaces. Shower installations in wet areas benefit from polymer-modified mortars.
Using the wrong mortar leads to hollow spots behind tiles — areas where the tile isn’t fully bonded to the substrate. Over time, hollow-backed tile is prone to cracking and loosening, particularly in wet areas where thermal cycling and moisture expansion add stress.
DIY Tile Installation: Where It Can Work
DIY tile installation isn’t universally inadvisable. There are applications where a careful, patient homeowner can produce acceptable results.
Good DIY candidates:
- A small, low-moisture area, like a laundry room floor or an entryway with a simple layout
- Backsplash tile on kitchen walls where moisture requirements are lower
- Replacing a few broken tiles in an existing installation
Poor DIY candidates:
- Shower floors and walls — the waterproofing requirements are too consequential for inexperienced installation
- Large-format tile — the subfloor prep and leveling requirements are more demanding
- Any wet area with complex cuts around fixtures, drains, or recessed niches
- Bathrooms in older homes where subfloor conditions are uncertain
The honest assessment: bathrooms are specifically where DIY tile installation carries the highest risk of failure and the highest cost when it fails. The surfaces that matter most in a bathroom renovation — shower floors and walls — are the surfaces that require the most technical precision. That’s where professional installation earns its value most clearly.
Handyman vs. Professional Tile Contractor
This distinction matters more than many homeowners realize. “Handyman” covers a wide range of capabilities. Some handymen have genuine tile installation experience and do good work. Others do tile occasionally alongside dozens of other home services and don’t have the depth of technique that comes from specialization.
The difference between someone who tiles occasionally and someone who tiles every day for decades is real and shows up in the finished product. Consider:
Daily practice: A professional tile setter installs tile regularly. Their mortar consistency, trowel technique, cut precision, and grout application are refined by repetition. These are physical skills that improve with practice.
Material knowledge: Professional tile contractors know which mortars work with which tile types, which grout formulations perform in wet areas, and which waterproofing systems are appropriate for different substrate conditions. This knowledge comes from training and experience, not occasional exposure.
Accountability: A dedicated flooring company with a named installer team has reputation and accountability on the line with every job. A general handyman has less riding on any single project in their broad service portfolio.
Warranty terms: Professional tile contractors at established companies back their work with defined warranty coverage. Leicester Flooring backs every installation with a lifetime workmanship warranty — if the installation work itself develops a problem, we make it right. That kind of warranty isn’t available from a generalist handyman.
What Professional Tile Installation Actually Includes
When you hire Leicester Flooring for bathroom tile installation, here’s what you’re getting beyond just someone laying tile.
Free in-home measure: We come to your home before any commitment, assess the space, check subfloor conditions, identify anything that could affect the project, and provide an accurate written estimate. You know exactly what you’re paying for before work begins.
Subfloor assessment and preparation: We check for flatness, structural adequacy, and moisture conditions. If cement backer board is needed, we install it. If subfloor repair is required, we address it and tell you upfront.
Proper waterproofing in wet areas: Shower installations include the application of a waterproofing membrane. We don’t skip it, abbreviate it, or treat it as an optional upgrade.
Tile layout planning: We lay out the installation dry before any mortar is applied, optimizing placement to minimize waste and ensure the finished floor looks planned and balanced.
Correct mortar and adhesive for the tile and application: We use the appropriate mortar formulation for the tile type, format, and moisture conditions of the installation area.
Precision cutting: Our installers make clean, accurate cuts around fixtures, drains, door thresholds, and other penetrations. The quality of cuts at details defines the quality of a tile installation.
Professional grouting and sealing: Grout is applied consistently, cleaned from tile faces before it hardens, and sealed appropriately before we leave.
Cleanup: We leave your home clean and walkable. Installation generates a mess; we take responsibility for removing it.
Lifetime installation warranty: Our workmanship is guaranteed. If something goes wrong with how the tile was installed, we come back and fix it.

Questions to Ask Any Tile Contractor
If you’re evaluating tile contractors beyond Leicester Flooring, here are the questions that matter most.
Are your installers direct employees or subcontractors? Direct employees mean the company has ongoing accountability for their work. Subcontractors change job to job and may have less stake in any particular project.
What waterproofing system do you use in shower installations? A professional should be able to name the product and explain the application process. “We use cement board” is not an answer — cement board is not waterproofing.
What mortar do you use for large-format tile? The answer should reference the back-buttering technique and a modified mortar appropriate for low-absorption surfaces. Vague answers here suggest limited technical depth.
Do you lay tile out dry before setting? This should be standard practice. Any contractor who doesn’t do this is skipping a critical quality step.
What does your warranty cover? Get specifics. “We stand behind our work” is not a warranty.
Can I see examples of recent work? Established local contractors have references and examples available.

Frequently Asked Questions
How much does professional tile installation cost compared to DIY?
Professional installation costs more upfront than doing it yourself, primarily in labor. The gap narrows when you account for the tools required for DIY tile work (wet saw, notched trowels, backer board scoring tools, grout float), the cost of mistakes and material waste from inexperience, and the value of a lifetime installation warranty. For bathroom tile specifically, where failures are expensive to fix, the professional installation premium is usually worth it.
What if I want to tile my own entryway or backsplash?
For lower-stakes applications without wet area requirements, DIY tile work is more reasonable. If you want to discuss whether a specific project is a good DIY candidate, our showroom team is happy to talk it through honestly. We’d rather help you make the right decision than oversell professional installation where it’s not needed.
How do I know if a previous DIY tile installation in my bathroom has problems?
Common signs of improperly installed tile include: grout that crumbles or falls out, tiles that sound hollow when tapped, grout lines that crack consistently in the same locations, tiles that have shifted or feel loose, and any evidence of moisture staining on walls or ceilings adjacent to the shower. If you’re seeing any of these, a professional assessment is worthwhile before the damage gets worse.
Does Leicester Flooring offer warranties on the tile products themselves?
Yes. In addition to our lifetime installation workmanship warranty, the American-made tile products we carry come with manufacturer warranties. Our flooring services page covers what’s included when you work with us.
What’s included in Leicester’s lifetime installation warranty?
Our lifetime warranty covers the workmanship of our installation team — the installation work itself. If tile lifts, grout fails due to installation error, or another installation-related issue develops, we return and address it at no cost. The warranty is on the labor and technique, not on normal wear of the tile or grout over time.
Summary
Professional tile installation and DIY tile installation are different categories of outcome, not just different categories of cost. The technical requirements of bathroom tile — subfloor preparation, waterproofing in wet areas, mortar selection, layout planning, and precision cuts — reward dedicated expertise and daily practice. Failures in bathroom tile installation cost far more to fix than the installation itself.
Leicester Flooring has been doing this work for over 50 years in WNC homes. Our experienced installers, American-made products, and lifetime workmanship warranty are the most concrete evidence we can offer that professional installation is worth the investment.
