Crack assessment is the inspection and evaluation of cracks in a swimming pool to determine cause, severity and the most appropriate repair or renovation approach. We inspect the crack, check surrounding finishes and equipment, and recommend a course of action that protects the pool structure and the investment in the outdoor living space.
What a crack assessment covers
A crack assessment is a systematic check of the pool shell, finish and adjacent elements. We look for visible cracks in plaster or concrete, separation at coping or tiles, stains that follow a hairline, and any signs that the crack is changing over time. The assessment includes a review of equipment, water level history and any landscape or grading issues that could affect the shell.
We do not replace a structural engineer on every job, but we do record measurements, photo documentation and a risk rating. For cracks that show movement, leaks, or signs of structural distress we recommend engineered analysis before permanent resurfacing.
Why crack assessment matters in Lewisville and the Dallas Fort Worth area
Pools in Lewisville and across the Dallas Fort Worth area face the same stresses that affect many local properties. Soil movement, seasonal moisture changes and older plaster finishes can all contribute to cracking. Early assessment helps prevent small defects from turning into larger repairs, and it helps homeowners, HOAs and property managers budget a renovation or resurfacing project with fewer surprises.
When we assess cracks we consider local factors like yard grading, nearby trees and irrigation, and the age of the existing finish. That local context shapes whether the right treatment is a focused repair, a full resurface, or a broader renovation that includes coping and equipment work.
Key concepts every property owner should know
- Hairline cracks. Thin surface cracks in plaster that often do not indicate structural failure but can allow staining and will usually require resurfacing to fully correct.
- Shrinkage cracks. Small fissures that occur as plaster cures. They are common in some finishes and sometimes stable, but they can widen with time.
- Structural cracks. Wider cracks that cross the shell or run through coping. These suggest movement or settlement and need more investigation.
- Coping and bond beam separation. Gaps where coping meets the shell can let water and soil move against the structure, which accelerates damage.
- Delamination and plaster loss. Areas where the finish detaches from the substrate often appear as irregular flakes or exposed aggregate and usually require resurfacing.
- Leak indicators. Rapid changes in the water level, persistent damp spots near the pool, or new cracks after heavy rain may indicate an active leak that needs prompt assessment.
How we evaluate cracks step by step
- Visual inspection. We document crack location, length and width with photos and notes. We check finishes, tile and coping.
- Movement test. We mark the ends of the crack and return to compare measurements. If the crack is changing, that raises the urgency.
- Water test. If a leak is suspected we use bucket tests, dye testing and water level monitoring to see whether the pool is losing water from the shell or from evaporation and splash out.
- Context review. We evaluate site grading, irrigation, nearby trees and historical repairs. That helps determine whether soil or loading has stressed the shell.
- Repair plan and options. We outline repair options from cosmetic patching and relining to resurfacing or structural repair. When structural issues are suspected we advise bringing a structural engineer into the process.
Documentation tip: take photos from multiple angles and note when you first observed the crack and any events like heavy storms or construction nearby.
Comparing common crack types and typical responses
| Crack type | Typical sign | Usual response |
|---|---|---|
| Hairline surface crack | Thin line in plaster without separation | Monitor and schedule resurfacing when finish shows wear |
| Shrinkage crack | Short, irregular fissure near finish transitions | Often cosmetic repair or patching during resurfacing |
| Structural crack | Wide crack that crosses shell or moves over time | Engineer review, structural repair, then resurfacing |
| Coping separation | Gap between coping and shell, loose tiles | Address coping and bond beam, correct drainage, then refinish |
Checklist for when to call a professional
Signs that need professional assessment
- Cracks longer than a few inches or wider than a hairline
- Persistent or accelerating water loss
- Separation at coping, tiles falling loose, or visible settlement
- Cracks that appear after grading, tree removal or nearby construction
- Cracks that expose aggregate or leave the substrate bare
Pro tip: Keep a dated photo timeline. Photos taken monthly during dry and wet seasons make it easier to show whether a crack is stable or changing.
Common homeowner questions about pool cracks
We answer the most frequent questions we see from homeowners, HOAs and property managers.
- Can I patch a crack myself? Small cosmetic patches are possible, but they rarely address underlying causes. DIY patching can hide a growing issue and complicate later repairs. We recommend a professional assessment to choose the right long term solution.
- Will resurfacing hide cracks? Resurfacing can correct surface cracks and restore a watertight finish, but if the crack is structural resurfacing alone is a short term fix. Structural problems should be stabilized first.
- How long before a crack becomes serious? That depends on cause and site conditions. Some hairline cracks remain stable for years. Cracks that change shape, leak or coincide with coping separation need prompt attention.
- Do we always need an engineer? Not always. Many cracks are cosmetic. We recommend an engineer when cracks show movement, when there is significant settlement, or when repairs would affect structural elements like the bond beam or coping.

Key takeaway
A crack assessment identifies cause and risk, and it guides whether a repair, resurfacing, structural work or a full renovation is the proper next step. In Lewisville and the Dallas Fort Worth area local site conditions matter, so documented inspection and measured recommendations reduce surprises and protect your pool investment.
Frequently asked questions
What causes cracks in pool plaster and concrete?
Common causes include normal cure shrinkage in finishes, ground movement, tree roots, poor drainage, freeze thaw cycles in some climates, and structural settlement. The pool age and quality of the original installation also affect risk.
How quickly should I act on a new crack?
If the crack is hairline and the finish is otherwise sound you can monitor it, but document it. If the crack widens, leaks, or appears with coping separation you should arrange a professional assessment promptly.
Will resurfacing fix every crack?
Resurfacing fixes surface and finish related cracks and restores a watertight interior. If the crack reflects structural movement resurfacing alone will not be a long term solution. Structural issues need to be addressed first.
Do you always need to drain the pool to assess or repair a crack?
Not always. Many inspections and some repairs are performed with the pool partially full. Full drainage is avoided when possible because it can change shell stresses. We evaluate on a case by case basis and follow best practices for safety and finish work.
When is an engineer necessary?
An engineer is advisable when cracks show active movement, when there is obvious settlement or rotation of the shell, or when repairs would affect bond beams and other structural elements. We coordinate with engineers when their reports are appropriate to the scope of work.
